Money-making machines

A new small-mechanization pilot initiative launched in July is equipping farmers with the business and technical skills they need to provide mechanization services to communities in six wards of Masvingo district, Zimbabwe.

With funding from the Swiss Agency for Development and Cooperation (SDC) managed by the United Nations World Food Program (WFP), the International Maize and Wheat Improvement Center (CIMMYT) is leading implementation of the pilot in collaboration with Kurima Machinery and the Zimbabwe Agriculture Development Trust (ZADT), who are supporting the technical training and financial management, respectively.

Anchored on a strong business model, 15 farmers have signed up to become service providers and invested an initial deposit of $500 to access the mechanization package comprising a two-wheel tractor and trailer, a direct planter and a maize cob sheller. Through a “lease-to-own” credit facility, eligible service providers will have 24 months to pay the remaining balance for the set of equipment.

“This approach addresses re-payment challenges in past interventions, where equipment was distributed without a firm commitment from the service providers and without putting in enough effort to establish a viable business,” says Christian Thierfelder, a cropping systems agronomist at CIMMYT. “An advantage of this new form of financial commitment by the service providers is that it guarantees full participation and a change in their perception towards farming as a business.

Since 2013, smallholder farmers in Zimbabwe have been exposed to the benefits of combining small-mechanization with conservation farming systems to improve productivity — land preparation, planting and harvesting to achieve higher yields while reducing production costs. Besides making farming tasks more efficient for individuals, this set of equipment can be used to provide critical services to other farmers in their wards.

The two-wheel tractor can have various implements attached to it for services such as planting, transportation and shelling. It can also be used to run other important implements such as water pumps, mills or threshers.

This mechanization pilot therefore presents an additional pathway out of poverty and into sustainable production and income generation at household level, while boosting the local economy and rural employment in Masvingo district.

Training for local service provision

Eligible service providers were recently invited to attend a one-week specialized business and technical training course at Gwebi Agricultural College, just outside of Harare. The training package consisted of two main components: business management; and two-wheel tractor operation, maintenance and repair.

Elliot Zvovovo, a participating service provider, explains how the balanced training approach equipped him fully with all the knowledge and skills he needs to run his business. “I learned different ways of record keeping, managing income and treating my clients professionally,” he says.

“On the machinery side, I learned about of all the parts of a two-wheel tractor and practiced assembling the engine so that maintenance and repair will be easy for me.”

Julius Shava, another participating service provider, agrees, adding that knowing how to maintain the two-wheel tractor and troubleshooting will also minimize costs of hiring external mechanics to attend to faults. “I realized the importance of routine checks for oil and water levels, how to crank-start the tractor and hitch the planter all by myself.”

Supporting agricultural extension in line with service providers is critical to mainstreaming transformational change in rural areas. As such, seven local extension officers — key partners in the implementation of small-mechanization activities — were also invited to participate in the training.

“The training proved to be very effective, particularly the emphasis on mastering business principles and on the technical side, integrating service providers’ existing knowledge of conservation farming with small-mechanization,” says Canaan Zhakata, an extension officer for Ward 15.

Through the practical sessions, all service providers have now learned how to operate a two-wheel tractor, calibrate the direct planter for seed and fertilizer rates and use the sheller — giving them full technical skills and knowledge,” explains Dorcas Matangi, a research associate at CIMMYT.

The certification they have received will increase farmers’ confidence as they return to Masvingo to commence service delivery, with continued on-site support from their local extension officers. “Once we return to Masvingo, we can assist the new service providers by monitoring their service delivery to ensure full compliance with the technical requirements for operating the machinery,” says Tsvakai Dumbu, an extension officer for Ward 17.

A profitable business for the local economy

This mechanization pilot is poised for success as it draws on existing positive results gained by the women and youth service providers in western Zimbabwe, who are running successful mechanized enterprises following the recently completed Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project.

“During a recent seed fair, we heard of a youth group in Makonde that is making up to $7,000 just from maize shelling services,” says Zvovovo. “Knowing that it takes just one day to shell up to three tons of maize with the sheller, I now know that reaching such an income is achievable.”

This pilot will prove that there is scope for small-mechanization to expand on productivity through the two-wheel tractor, trailer and sheller, as shown in other parts of eastern and southern Africa. It will explore leverages on the opportunities and demand for services in Masvingo.

Molecular breeding speeds development of better seeds

To adequately confront rapidly changing plant pests and diseases and safeguard food security for a growing population, breeders — in collaboration with their partners — have to keep testing and applying new breeding methods to deliver resilient seed varieties at a much faster rate using minimal resources. Molecular markers are essential in this regard and are helping to accelerate genetic gains and deliver better seed to smallholders across sub-Saharan Africa in a much shorter timeframe.

Progress made so far in molecular plant breeding, genetics, genomic selection and genome editing has contributed to a deeper understanding on the role of molecular markers and greatly complemented breeding strategies. However, phenotyping remains the single most costly process in plant breeding, thus limiting options to increase the size of breeding programs.

Application of molecular markers increases the ability to predict and select the best performing lines and hybrids, prior to selection in the field. “This enables breeders to expand the size of a breeding program or the populations they work on using the same amount of resources,” says Manje Gowda, a maize molecular breeder at the International Maize and Wheat Improvement Center (CIMMYT).

“There are three stages in the use of molecular markers: discovery, validation and deployment,” he explains. “At the discovery phase, the objective is to find molecular markers associated or tightly linked with the trait of interest, while also assessing whether the trait is more complex or easier to handle with few markers for selection.”

The molecular markers identified at the discovery stage are validated in independent bi-parental or backcross populations, and the marker trait associations — which are consistent across different genetic backgrounds and diverse environments — are then moved to the deployment stage. Here, they are considered for use in breeding either as part of marker assisted selection or forward breeding, marker assisted back crossing and marker assisted recurrent selection.

Screening for resistance markers

CIMMYT scientists have discovered several marker trait associations for crop diseases including maize lethal necrosis (MLN), maize streak virus (MSV), corn rust and turcicum leaf blight. All these trait-associated markers have been validated in biparental populations.

For MLN, after screening several thousands of lines, researchers identified a few with resistance against the viral disease, namely KS23-5 and KS23-6. These lines were obtained from synthetic populations developed by Kasetsart University in Thailand and serve as trait donors. Researchers were able to use these as part of forward breeding, producing doubled haploid (DH) lines by using KS23-6 as one parent and screening for the presence of MLN resistance genes.

“This screening helps eliminate the lines that may carry susceptible genes, without having to phenotype them under artificial inoculation,” says Gowda. “These markers are also available to all partners to screen for MLN resistance, thereby saving on costs related to phenotyping.”

Scientists also used these MLN resistance markers to introgress the MLN resistance into several elite lines that are highly susceptible to the disease but have other desirable traits such as high grain yield and drought tolerance. The marker-assisted backcrossing technique was used to obtain MLN resistance from the KS23-5 and KS23-6 donor lines. This process involves crossing an elite, commercial line — as a recurrent parent in the case of CIMMYT elite lines — with a donor parent line (KS23) with MLN resistance. These were then backcrossed over two to three cycles to improve the elite line carrying MLN resistance genes. In the past three years, more than 50 lines have been introgressed with the MLN resistance gene from KS23-6 donor line.

An impetus to breeding programs

“The work Manje Gowda has been carrying out is particularly important in that it has successfully moved from discovery of valuable markers and proof-of-concept experiments to scalable breeding methods which are being used effectively,” says CIMMYT Trait Pipeline and Upstream Research Coordinator Mike Olsen. “Enabling routine implementation of molecular markers to increase selection efficiency of breeding programs in the context of African maize improvement is quite impactful.”

At CIMMYT, Gowda’s team applied genomic selection at the early stage of testing the breeding pipeline for different product profiles. “The objective was to testcross and phenotype 50% of the Stage One hybrids and predict the performance of remaining 50% of the hybrids using molecular markers,” Gowda explains.

The team have applied this strategy successfully each year since 2017, and the results of this experiment show that selection efficiency is the same as when using phenotypic selection, but using only 32% of the resources. From 2021 onwards, the aim is to use the previous year’s Stage One phenotypic and genotypic data to predict 100% of the lines. This will not only save the time but improve efficiency and resource use. The previous three-year Stage One historical data is helping to reduce the phenotyping of lines from 50% to 15%, with an increase in saving resources of up to 50%.

For the commercial seed sector, integrating molecular marker-based quality control measures can help deploy high-quality seeds, an important factor for increasing crop yields. In sub-Saharan Africa, awareness on marker-based quality has improved due to increased scientist and breeder trainings at national agricultural research systems (NARS), seed companies and national plant protection organizations, as well as regulators and policymakers.

Currently, many NARS and private sector partners are making it mandatory to apply marker-based quality control to maintain high-quality seeds. Since NARS and small- and medium-sized seed companies’ breeding programs are smaller, CIMMYT is coordinating the collection of samples from different partners for submission to service providers for quality control purposes. CIMMYT staff are also helping to analyze quality control data and interpret results to sharing with partners for decision-making. For the sustainability of this process, CIMMYT is training NARS partners on quality control, from sample collection to data analyses and interpretation, and this will support them to work independently and produce high-quality seed.

Such breeding improvements have become indispensable in supporting maize breeding programs in the public and private sectors to develop and deliver improved maize varieties to smallholder farmers across sub-Saharan Africa.

Q&A: CGIAR investment has generated returns of 10 times the amount invested

Disclaimer: The views and opinions expressed in this article are those of Philip Pardey and do not necessarily reflect the official views or position of the International Maize and Wheat Improvement Center (CIMMYT).

Working with national agricultural research centers (NARS), CGIAR centers, including the International Maize and Wheat Improvement Center (CIMMYT), have played a pivotal role in staving off the last global food crisis, mainly through enhancing the yields of staple food crops like cereals.

A new report, commissioned by the Supporters of Agricultural Research (SoAR) Foundation and authored by experts from the University of California, Davis, the University of Minnesota and North Dakota State University shows that over the past five decades, CGIAR investment has generated returns of 10 times the amount invested.

We caught up with co-author Philip Pardey, a professor at the University of Minnesota and Director of the university’s GEMS Informatics Center, to discuss the report’s implications, the importance of collaboration between NARS and CGIAR, and why investment in agricultural research and development (R&D) is needed now more than ever.

According to the report, CGIAR investment has returned a benefit-cost ratio of 10:1. How does this compare to other government investments?

A benefit-cost ratio of 10:1 means that on average, a dollar invested today brings a future return equivalent to $10 in present-day value. This is high: any ratio over the threshold of 1:1 justifies investment.

This indicates that governments — and others who invest in CGIAR and related public food and agricultural R&D — would have profited society by doing more agricultural R&D compared with the investment opportunities normally available to them. Opportunities for investment in other national and global public goods, like education and infrastructure, might also have yielded very high returns, but there is no comparable evidence that those other opportunities yielded similar return on investments.

Drawing on the findings of this report, and other related work, we conclude that the economic evidence justifies at least a doubling of overall investments in public food and agricultural R&D.

The report shows evidence of massive underinvestment in agricultural research and development (R&D) in past years. Why is that?

As we show in the report, inflation adjusted CGIAR funding has declined sharply by around 25% in the past few years. There is nothing in the economic evidence that justifies this scaling back.

Some commentators have suggested that the easy gains from agricultural R&D have already been made and that the historical returns-to-research evidence is no longer representative of the returns to more recent R&D. However, the empirical evidence refutes that notion. For example, a 2019 study from Rao et al. showed that the contemporary returns of agricultural R&D are as high as ever.

What are the risks of continuing on this path of underinvestment in agricultural R&D?

In the second half of the 20th century, global food supply grew faster than demand and real food prices fell significantly, alleviating hunger and poverty for hundreds of millions around the world. Whether or not that pattern can be repeated in the first half of the 21st century will depend crucially on investments in agricultural R&D, including investments made through CGIAR.

Global demand for food is projected to grow by 70% from 2010 to 2050. Simply meeting that increased demand will call for transformative innovations in agriculture to adapt to a changing climate, combat co-evolving pests and diseases, and increase productivity of a fairly fixed land base and a shrinking supply of agricultural water. To make food abundant and affordable for the increasingly urban, poorest of the poor demands doing much more — and much better — than simply keeping up.  If adequate investments in agricultural R&D are absent, even the odds of keeping up look increasingly questionable.

Your report shows that returns are a joint effort between NARS and CGIAR. Can you elaborate on that?

The impact evidence we reviewed for our study made clear that the success of CGIAR research is inextricably intertwined with research undertaken by national programs. In fact, this national-international R&D connectedness makes it difficult to figure out what share of the overall benefits from research are attributable to CGIAR or national innovation systems.

CGIAR has appropriately shifted its attention to low-income countries that are still heavily dependent on agriculture for livelihoods and food security. These also tend to have lower national R&D capacities and more fragile innovation systems, as well as limited, albeit emerging, private sector capabilities to support their food and agricultural sectors.

Supporting the evolution of agricultural innovation systems within CGIAR’s target economies requires doubling down on technology discovery, adaptation and delivery activities.

How can CGIAR better meet current global food challenges?

CGIAR has been demonstrably successful as an international instrument of technology discovery and in enhancing the international transfer, or spillover, of these new technologies. Tackling longer term agricultural technology challenges has been a key part of past successes.

However, a significant share of the funding for the CGIAR appears to have shifted away from the more strategic development of international public innovation goods to more localized economic development activities with a technology component. For example, the share of unencumbered CGIAR funding shrank from around 80% in 1971 to 50% in 2000, and since 2010 has plummeted to very low levels. The impact evidence provides little support for the notion that this shift in funding, which often implies a greater emphasis on more localized and shorter-term activities, is a high payoff strategy that best leverages CGIAR’s comparative advantages.

As it continually repositions its role as a source of international public innovation goods targeted to agriculturally dependent low-income countries, CGIAR will need to rethink how it partners with the public agencies, universities and private research entities that are the major source of innovations in food and agriculture.

When CGIAR was founded, a large share of the world’s agricultural R&D was done by public agencies in rich countries. Now the agriculturally large, middle-income countries spend on par with the rich countries, and the innovation landscape in rich and many middle-income countries is increasingly dominated by private firms. This comes with new partnership opportunities for CGIAR, but also new challenges, not least given the increasingly proprietary nature of the innovations and data that are driving developments in the food and agricultural sectors.

In your report you have documented clear evidence to support investment in agricultural R&D. What are the next steps in engaging national governments and decision makers to get agricultural R&D back on their agendas?

Today, as in the past, funding streams for CGIAR research are in decline and under threat. This mirrors a pattern of declining public support over recent decades for agricultural R&D conducted by national programs in many of the world’s richer countries.

However, public expectations about the roles of government to address glaring market failures may be realigning. For instance, the COVID-19 crisis exposed weakness in many public health systems, with calls for renewed and hopefully sustained, long-term investments in these public programs. COVID has also revealed the fragility of food supply systems, even in rich countries. The tide of public opinion also seems to be turning regarding the growing risks associated with climate change.

Evidence-based efforts to communicate the inter-relatedness between climate, public health and agriculture risks, and the role of innovation in reducing these growing risks over the decades ahead is critical to right-sizing and realigning the public roles in agricultural R&D.

Just as strong public investments play a crucial and complimentary role regarding significant private investments in health research, so too does the basic and pre-competitive research, undertaken with public funding, prime the pump for the growing private roles in agricultural innovation.

And even as the worldwide demand for more diversified diets continues to increase, demand for staple crops such as wheat and maize will also continue to grow and will remain crucial to securing favourable nutrition and food security outcomes in the decades ahead. Innovations in agriculture are hard won, and there are long lags (often a decade or more) between spending on agricultural R&D and getting new crop technologies in the hands of farmers. Thus there is a real sense of urgency to revitalize the investments in agricultural R&D required to produce the innovations that are needed now more than ever to sustainably feed the world.

Breaking Ground: Rahel Assefa thrives off witnessing impact

Ethiopia-born Rahel Assefa began her career as a software engineer in a children’s hospital in Washington DC, USA. Although she enjoyed this work for the first few years, she found that it was not as fulfilling as she had initially hoped.

Rahel slowly started shifting gears towards a new career, initially pursuing an MSc in Project Management. “I knew that I was meant to work in an area where I would have direct interaction and impact, so I really thrived in that environment,” she explains.

Her work was highly appreciated by senior managers and she quickly progressed in this new career path. “I was soon recruited to help build a project management office from scratch and that solidified my interest in the field.”

A return to Africa

Rahel remained in health care for the next few years, taking on roles in portfolio and business relationship management but ultimately, she knew her next step would be to return to Africa and work in a field that contributes to supporting people’s livelihoods. 

In 2015, Rahel learned of a job opening at the International Maize and Wheat Improvement Center (CIMMYT) which was suitable to her skillset and would also serve her desire of moving to Africa. She applied and joined the organization in February 2016, moving to Addis Ababa with her young family in tow. “We had always discussed returning to Africa, and preferably to Ethiopia, so this was a welcome move. But it was also a big leap into the unknown because both my husband and I had left Ethiopia during our formative years,” she says.

Rahel had also never worked in the agricultural sector before joining CIMMYT, so there was a steep learning curve to contend with, as well as the cultural shifts she had to make to adjust to her new work environment. “I remember spending my first few days on the job taking the time to just observe, listen actively and ask questions.”

Witnessing impact first-hand

Rahel now works as a project manager and as the regional program manager for CIMMYT’s Sustainable Intensification Program in Africa. “Working at CIMMYT is interesting because I get to collaborate with such a diverse group of people, and we can see that our work has a direct impact on the day-to-day lives of farmers,” she says. “It’s always rewarding to see first-hand how the life of a farmer, woman or young person is transformed because of the work we do.”

“I also find working at CIMMYT’s Ethiopia office enjoyable simply because everyone gets along well,” she explains. Rahel particularly appreciates the Thursday morning coffee gatherings for staff hosted at the International Livestock Research Institute (ILRI) campus, and her frequent interactions with colleagues in Kenya and Zimbabwe, where she travels regularly. “I love having the opportunity to see the work colleagues do on the ground across Africa and I’m always in awe of their dedication to the work they do.”

When she’s not visiting projects in Nairobi or Harare, Rahel cherishes the time she spends with her family and young son, Adam, who seems to be developing a keen interest in agriculture himself. “He loves visiting ‘mommy’s office’ from time to time,” she explains, “and as a result he has recently even attempted to plant maize and wheat in our back garden.”

“CIMMYT is at my heart”

After a 37-year career, Hans-Joachim Braun is retiring from the International Maize and Wheat Improvement Center (CIMMYT). As the director of the Global Wheat Program and the CGIAR Research Program on Wheat, Braun’s legacy will resonate throughout halls, greenhouses and fields of wheat research worldwide.

We caught up with him to capture some of his career milestones, best travel stories, and vision for the future of CIMMYT and global wheat production. And, of course, his retirement plans in the German countryside.

Major career milestones

Native to Germany, Braun moved to Mexico in 1981 to complete his PhD research at CIMMYT’s experimental station in Obrégon, in the state of Sonora. His research focused on identifying the optimum location to breed spring wheat for developing countries — and he found that Obrégon was in fact the ideal location.

His first posting with CIMMYT was in Turkey in 1985, as a breeder in the International Winter Wheat Improvement Program (IWWIP). This was the first CGIAR breeding program hosted by a CIMMYT co-operator, that later developed into the joint Turkey, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) winter wheat program. “In 1990, when the Commonwealth of Independent States was established, I saw this tremendous opportunity to work with Central Asia to develop better wheat varieties,” he said. “Today, IWWIP varieties are grown on nearly 3 million hectares.”

Although Braun was determined to become a wheat breeder, he never actually intended to spend his entire career with one institution. “Eventually I worked my entire career for CIMMYT. Not so usual anymore, but it was very rewarding. CIMMYT is at my heart; it is what I know.”

“Make the link to the unexpected”

One of Braun’s standout memories was a major discovery when he first came to Turkey.  When evaluating elite lines from outside the country — in particular lines from a similar environment in the Great Plains — his team noticed they were failing but nobody knew why.

Two of his colleagues had just returned from Australia, where research had recently identified micronutrient disorders in soil as a major constraint for cereal production. The team tried applying micro-nutrients to wheat plots, and it became crystal clear that zinc deficiency was the underlying cause. “Once aware that micro-nutrient disorders can cause severe growth problems, it was a minor step to identify boron toxicity as another issue. Looking back, it was so obvious. The cover picture of a FAO book on global soil analysis showed a rice field with zinc deficiency, and Turkey produces more boron than the rest of the world combined.”

“We tested the soil and found zinc deficiency was widespread, not just in the soils, but also in humans.” This led to a long-term cooperation with plant nutrition scientists from Cukurova University, now Sabanci University, in Istanbul.

But zinc deficiency did not explain all growth problems. Soil-borne diseases — cyst and lesion nematodes, and root and crown rot — were also widespread. In 1999, CIMMYT initiated a soil-borne disease screening program with Turkish colleagues that continues until today.  Over the coming decade, CIMMYT’s wheat program will make zinc a core trait and all lines will have at least 25% more zinc in the grain than currently grown varieties.

After 21 years in Turkey, Braun accepted the position as director of CIMMYT’s Global Wheat Program and moved back to Mexico.

Partnerships and friendships

Braun emphasized the importance of “mutual trust and connections,” especially with cooperators in the national agricultural research systems of partner countries. This strong global network contributed to another major milestone in CIMMYT wheat research: the rapid development and release of varieties with strong resistance to the virulent Ug99 race of wheat rust. This network, led by Cornell University, prevented a potential global wheat rust epidemic.

CIMMYT’s relationship with Mexico’s Ministry of Agriculture and the Obregón farmers union, the Patronato, is especially important to Braun.

In 1955, Patronato farmers made 200 hectares of land available, free if charge, to Norman Borlaug. The first farm community in the developing world to support research, it became CIMMYT’s principal wheat breeding experimental station: Norman Borlaug Experimental Station, or CENEB.  When Borlaug visited Obregón for the last time in 2009, the Patronato farmers had a big surprise.

“I was just getting out of the shower in my room in Obregón when I got a call from Jorge Artee Elias Calles, the president of the Patronato,” Braun recalls. “He said, ‘Hans, I’m really happy to inform you that Patronato decided to donate $1 million.’”

The donation, in honor of Borlaug’s lifetime of collaboration and global impact, was given for CIMMYT’s research on wheat diseases.

“This relationship and support from the Obregón farmers is really tremendous,” Braun says. “Obregón is a really special place to me. I am admittedly a little bit biased, because Obregón gave me a PhD.”

A worldwide perspective

Braun’s decades of international research and travel has yielded just as many stories and adventures as it has high-impact wheat varieties.

He remembers seeing areas marked with red tape as he surveyed wheat fields in Afghanistan in the 1990s, and the shock and fear he felt when he was informed that they were uncleared landmine areas. “I was never more scared than in that moment, and I followed the footsteps of the guy in front of me exactly,” Braun recalls.

On a different trip to Afghanistan, Braun met a farmer who had struggled with a yellow rust epidemic and was now growing CIMMYT lines that were resistant to it.

“The difference between his field and his neighbors’ was so incredible. When he learned I had developed the variety he was so thankful. He wanted to invite me to his home for dinner. Interestingly, he called it Mexican wheat, as all modern varieties are called there, though it came from the winter wheat program in Turkey.”

Seeing the impact of CIMMYT’s work on farmers was always a highlight for Braun.

CIMMYT’s future

Braun considers wheat research to be still in a “blessed environment” because a culture of openly-shared germplasm, knowledge and information among the global wheat community is still the norm. “I only can hope this is maintained, because it is the basis for future wheat improvement.”

His pride in his program and colleagues is clear.

“A successful, full-fledged wheat breeding program must have breeders, quantitative genetics, pathology, physiology, molecular science, wide crossing, quality, nutrition, bioinformatics, statistics, agronomy and input from economists and gender experts,” in addition to a broad target area, he remarked at an acceptance address for the Norman Borlaug Lifetime Achievement award.

“How many programs worldwide have this expertise and meet the target criteria? The Global Wheat Program is unique — no other wheat breeding program has a comparable impact. Today, around 60 million hectares are sown with CIMMYT-derived wheat varieties, increasing the annual income of farmers by around $3 billion dollars. Not bad for an annual investment in breeding of around $25 million dollars. And I don’t take credit for CIMMYT only, this is achieved through the excellent collaboration we have with national programs.”

A bright future for wheat, and for Braun

After retirement, Braun is looking forward to settling in rural Inzlingen, Germany, and being surrounded by the beautiful countryside and mountains, alongside his wife Johanna. They look forward to skiing, running, e-biking and other leisure activities.

“One other thing I will try — though most people will not believe me because I’m famous for not cooking — but I am really looking into experimenting with flour and baking,” he says.

Despite his relaxing retirement plans, Braun hopes to continue to support wheat research, whether it is through CIMMYT or through long friendships with national partners, raising awareness of population growth, the “problem of all problems” in his view.

“We have today 300 million more hungry people than in 1985. The road to zero hunger in 2030 is long and will need substantial efforts. In 1970, Organization for Economic Co-Operation and Development (OECD) countries agreed to spend 0.7% of GDP on official development assistance. Today only 6 countries meet this target and the average of all OECD countries has never been higher than 0.4%. Something needs to change to end extreme poverty — and that on top of COVID-19. The demand for wheat is increasing, and at the same time the area under wheat cultivation needs to be reduced, a double challenge. We need a strong maize and wheat program. The world needs a strong CIMMYT.”

An instant seed market

How do you create the largest market for stress-tolerant seed away from a major business center and attract over 1000 smallholder farmers in two days? Organize a seed fair to strengthen knowledge and information sharing.

The availability, access and use of climate-resilient seed by smallholder farmers in Zimbabwe is often hampered by transport costs, the distance between farming areas and viable seed markets, lack of public transport to business centers, and the inflated prices of seed and inputs by local agro-dealers. As a result, resource-poor farmers who cannot afford to purchase inputs resort to exchanging local seed retained or recycled from informal markets. This has devastating effects on farmers’ productivity, food and nutrition security.

Under the Zambuko/R4 Rural Resilience Initiative, the International Maize and Wheat Improvement Center (CIMMYT) is promoting climate-smart technologies and appropriate seed varieties alongside conservation agriculture (CA) systems in Masvingo district, Zimbabwe. Since 2018, mother and baby trials have successfully yielded results for smallholders in Ward 17 and additional mother trials have been introduced in Ward 13.

To overcome the challenges of seed access, CIMMYT partnered with eight seed companies — including Agriseeds, Mukushi and SeedCo — to host two seed fairs in October, targeting farmers in Wards 13 and 17. The intervention sought to address seed insecurity while reducing the knowledge gap on available stress-tolerant seed varieties by smallholder farmers.

Groundwork preparations led by the Department of Agriculture and Extension Services (AGRITEX) mobilized farmers from the host wards as well as farmers from neighboring wards 15, 19 and 25. In light of the ongoing COVID-19 pandemic, regulations relating to social distancing, the use of masks and sanitization were adhered to throughout the events.

Climate-smart seed choices

A key message delivered to the more than 1000 farmers who attended the seed fairs was the importance of their preference when selecting the right seed for their field. “Farmers must be critical when selecting seed and ensure that their preferred seed will perform well under the prevailing climatic conditions to give a good harvest,” said CIMMYT seed systems specialist Peter Setimela.

Seed company representatives were offered a platform to market their varieties and explain the benefits of each product on the market while leaving it to the farmers to decide on the most suitable variety for their own needs. “Farmers came early for the seed fairs and showed interest in our products,” said Norman Chihumo, a regional agronomist at Syngenta Distributors. “We recorded fairly good sales of seed and chemicals through cash purchases and vouchers.”

Later in the day, farmers toured the seed company stands to see the diverse maize varieties and small grains on offer — including millet and sorghum, cowpeas and groundnuts — and heard testimonials from participants in the mother and baby trials. “Listening to a success story from a farmer I know gives me the confidence to follow suit and buy seed that works in this harsh climate of ours,” said Joice Magadza, a farmer from Ward 17.

Local farmer Happison Chitono agreed. “I never used to grow cowpeas on my plot,” he explained, “but after learning about the ability it has to fix nitrogen into my soil and possibility of rotating the legume with maize, I am now gladly adding it to my seed input package.”

A seed fair is also a knowledge market

A key highlight of the seed fair was the learning platform promoting CIMMYT’s ongoing activities under the Zambuko/R4 Rural Resilience Initiative. Here, cropping systems agronomist Christian Thierfelder shared the objectives of this initiative with participating farmers.

“We know how good this seed is, but we also have to grow it in a sustainable way, so we make best use of the limited rainfall we receive in this area while we improve our soils,” he explained to farmers. “Cropping systems such as conservation agriculture combine no-tillage, mulching and crop rotation in a climate-smart agriculture way which enables farmers to harvest enough, even under heat and drought stress.”

Thierfelder also demonstrated the use of farm equipment promoted by CIMMYT in collaboration with Kurima Machinery, explaining how these can help reduce drudgery and save time on planting, transport and shelling.

Vouchers for transparent seed access

The seed fairs culminated in the distribution of seed and input vouchers. One hundred farmers were selected through a transparent raffle and redeemed their vouchers at their preferred seed company stands. They then also had the option to purchase additional seed, fertilizer and chemicals using their own cash.

Particularly high sales were recorded for Provitamin A orange maize, which sold out on both seed fair days. Stress-tolerant varieties such as ZM 309 and ZM 523 from Zimbabwe Super Seeds, ZM521 from Champion Seeds, and MRI 514 from Syngenta were also favorites among the farmers, while white sorghum and cowpea varieties such as CBC2 also sold well. Most of these varieties were already known to farmers as they had seen them growing for two years in CIMMYT’s mother trials of Ward 17.

The seed fairs ended on a high note with a total of 1.2 tons of seed sold to farmers on both days and agro-dealers hailed the fairs as a timely business venture for creating linkages and bringing seed suppliers on-site to assess their shops. A post-seed fair monitoring exercise will soon follow up on farmers’ use of the seed and the performance of demo packs and purchased varieties.

The Zambuko/R4 Rural Resilience Initiative supported by the United States Agency for International Aid (USAID), Swiss Agency for Development and Cooperation (SDC) and the World Food Programme (WFP) aims to increase farmer resilience and capacity to withstand climatic shocks and stresses in rural communities of Masvingo, Mwenezi and Rushinga in Zimbabwe.

Taking stock of the national toolbox

The Government of Ethiopia has consistently prioritized agriculture and sees it as a core component of the country’s growth. However, despite considerable efforts to improve productivity, poor management of soil health and fertility has been an ongoing constraint. This is mainly due to a lack of comprehensive site-and context-specific soil health and fertility management recommendations and dissemination approaches targeted to specific needs.

The government envisions a balanced soil health and fertility system that helps farmers cultivate and maintain high-quality and fertile soils through the promotion of appropriate soil-management techniques, provision of required inputs, and facilitation of appropriate enablers, including knowledge and finance.

So far, a plethora of different research-for-development activities have been carried out in support of this effort, including the introduction of tools which provide location-specific fertilizer recommendations. For example, researchers on the Taking Maize Agronomy to Scale in Africa (TAMASA) project, led by the International Maize and Wheat Improvement Center (CIMMYT), have created locally calibrated versions of Nutrient Expert® (NE) — a tool for generating fertilizer recommendations — for maize farmers in Ethiopia, Nigeria and Tanzania.

Nutrient Expert® is only one of the many fertilizer recommendation tools which have been developed in recent years covering different levels of applicability and accuracy across spatial scales and users, including smallholder farmers, extension agents and national researchers. However, in order to make efficient use of all the resources available in Ethiopia, there is a need to systematically evaluate the merits of each tool for different scales and use cases. To jump start this process, researchers from the TAMASA project commissioned an assessment of the tools and frameworks that have been developed, adapted and promoted in the country, and how they compare with one another for different use-cases. Seven tools were assessed, including Nutrient Expert®, the Ethiopian Soil Information System (EthioSIS) and RiceAdvice.

For each of these, the research team asked determined how the tool is currently being implemented — for example, as an app or as a generic set of steps for recommendation generation — and its data requirements, how robust the estimates are, how complicated the interface is, how easy it is to use, the conditions under which it performs well, and the spatial scale at which it works best.

Combining efforts and information

The results of this initial assessment indicate that the type of main user and the scale at which decisions are made varied from tool to tool. In addition, most of the tools considered have interactive interfaces and several — including Nutrient Expert® and RiceAdvice — have IT based platforms to automate the optimization of fertilizer recommendations and/or analyze profit. However, the source codes for all the IT based platforms and tools are inaccessible to end-users. This means that if further evaluation and improvements are to be made, there should be a means of collaborating with developers to share the back-end information, such as site-specific response curves and source codes.

Because most of the tools take different approaches to making fertilizer application site-specific, each of them renders unique strengths and trade-offs. For example, Nutrient Expert® may be considered strong in its approach of downscaling regionally calibrated responses to field level recommendations based on a few site-specific responses from farmers. By contrast, its calibration requires intensive data from nutrient omission trials and advice provision is time consuming.

Overall, the use of all the Site-Specific Decision-Support Tools (SSDST) has resulted in improved grain yields compared to when farmers use traditional practices, and this is consistent across all crops. On average, use of Nutrient Expert® improved maize, rice and wheat yields by 5.9%, 8.1% and 4.9%, respectively. Similarly, the use of RiceAdvice resulted in a 21.8% yield advantage.

The assessment shows that some of the tools are useful because of their applicability at local level by development agents, while others are good because of the data used to develop and validate them. However, in order to benefit the agricultural system in Ethiopia from the perspective of reliable fertilizer-use advisory, there is a need to develop a platform that combines the merits of all available tools. To achieve this, it has been suggested that the institutions who developed the individual tools join forces to combine efforts and information, including background data and source codes for IT based tools.

While the COVID-19 pandemic has disrupted efforts to convene discussions around this work, CIMMYT has and will continue to play an active advocacy role in supporting collaborative efforts to inform evidence-based reforms to fertilizer recommendations and other agronomic advice in Ethiopia and the wider region. CIMMYT is currently undertaking a more rigorous evaluation of these tools and frameworks as a follow up on the initial stocktaking activity.

Saving water and time

“I wonder why I never considered using drip irrigation for all these years,” says Michael Duri, a 35-year-old farmer from Ward 30, Nyanga, Zimbabwe, as he walks through his 0.5-hectare plot of onions and potatoes. “This is by far the best method to water my crops.”

Duri is one of 30 beneficiaries of garden drip-kits installed by the International Maize and Wheat Improvement Center (CIMMYT), an implementing partner under the Program for Growth and Resilience (PROGRESS) consortium, managed by the Zimbabwe Resilience Building Fund (ZRBF).

“In June 2020, I installed the drip kit across 0.07 hectares and quickly realized how much water I was saving through this technology and the reduced amount of physical effort I had to put in,” explains Duri. By September, he had invested in two water tanks and more drip lines to expand the area under drip irrigation to 0.5 hectares.

Water woes

Zimbabwe’s eastern highland districts like Nyanga are renowned for their diverse and abundant fresh produce. Farming families grow a variety of crops — potatoes, sugar beans, onions, tomatoes, leafy vegetables and garlic — all year round for income generation and food security.

Long poly-pipes lining the district — some stretching for more than 10 kilometers — use gravity to transport water from the mountains down to the villages and gardens. However, in the last five-to-ten years, increasing climate-induced water shortages, prolonged dry spells and high temperatures have depleted water reserves.

To manage the limited resources, farmers access water based on a rationing schedule to ensure availability across all areas. Often during the lean season, water volumes are insufficient for effectively irrigating the vegetable plots in good time, which leads to moisture stress, inconsistent irrigation and poor crop performance. Reports of cutting off or diverting water supply among farmers are high despite the local council’s efforts to schedule water distribution and access across all areas. “When water availability is low, it’s not uncommon to find internal conflicts in the village as households battle to access water resources,” explains Grace Mhande, an avid potato producer in Ward 22.

Climate-proofing gardens

Traditionally, flood, drag hose, bucket and sprinkler systems have been used as the main irrigation methods. However, according to Raymond Nazare, an engineer from the University of Zimbabwe, these traditional irrigation designs “waste water, are laborious, require the services of young able-bodied workers and use up a lot of time on the part of the farmers.”

Prudence Nyanguru, who grows tomatoes, potatoes, cabbages and sugar beans in Ward 30, says the limited number of sprinklers available for her garden meant she previously had to irrigate every other day, alternating the sprinkler and hose pipe while spending more than five hours to complete an average 0.05-hectare plot.

“Whereas before I would spend six hours shifting the sprinklers or moving the hose, I now just switch on the drip and return in about two or three hours to turn off the lines,” says Nyanguru.

The drip technology is also helping farmers in Nyanga adapt to climate change by providing efficient water use, accurate control over water application, minimizing water wastage and making every drop count.

“With the sprinkler and flood systems, we noticed how easily the much-needed fertile top soil washed away along with any fertilizer applied,” laments Vaida Matenhei, another farmer from Ward 30. Matenhei now enjoys the simple operation and steady precision irrigation from her drip-kit installation as she monitors her second crop of sugar beans.

Frédéric Baudron, a systems agronomist at CIMMYT, observes that Zimbabwe has a long history of irrigation, but this has mostly tended to be large-scale. “This means either expensive pivots owned by large-scale commercial farmers — a minority of the farming population in Zimbabwe as in much of sub-Saharan Africa — or capital-intensive irrigation schemes shared by a multitude of small-scale farmers, often poorly managed because of conflicts amongst users,” he says. A similar pattern can be seen with mechanization interventions, where Zimbabwe continues to rely on large tractors when smaller, and more affordable, machines would be more adapted to most farmers in the country.

“Very little is done to promote small-scale irrigation,” explains Baudron. “However, an installation with drip kits and a small petrol pump costs just over $1 per square meter.”

A disability-inclusive technology

The design of the drip-kit intervention also focused on addressing the needs of people with disabilities. At least five beneficiaries have experienced the limitations to full participation in farming activities as a result of physical barriers, access challenges and strenuous irrigation methods in the past.

For 37-year-old Simon Makanza from Ward 22, for example, his physical handicap made accessing and carrying water for his home garden extremely difficult. The installation of the drip-kit at Makanza’s homestead garden has created a barrier-free environment where he no longer grapples with uneven pathways to fetch water, or wells and pumps that are heavy to operate.

“I used to walk to that well about 500 meters away to fetch water using a bucket,” he explains. “This was painstaking given my condition and by the time I finished, I would be exhausted and unable to do any other work.”

The fixed drip installation in his plot has transformed how he works, and it is now easier for Makanza to operate the pump and switches for the drip lines with minimal effort.

Families living with people with disabilities are also realizing the advantages of time-saving and ease of operation of the drip systems. “I don’t spend all day in the field like I used to,” says George Nyamakanga, whose brother Barnabas who has a psychosocial disability. “Now, I have enough time to assist and care for my brother while producing enough to feed our eight-member household.”

By extension, the ease of operation and efficiency of the drip-kits also enables elderly farmers and the sick to engage in garden activities, with direct benefits for the nutrition and incomes of these vulnerable groups.

Scaling for sustained productivity

Since the introduction of the drip-kits in Nyanga, more farmers like Duri are migrating from flood and sprinkler irrigation and investing in drip irrigation technology. From the 30 farmers who had drip-kits installed, three have now scaled up after witnessing the cost-effective, labor-saving and water conservation advantages of drip irrigation.

Dorcas Matangi, an assistant research associate at CIMMYT, explains that use of drip irrigation ensures precise irrigation, reduces disease incidence, and maximal utilization of pesticides compared to sprinklers thereby increasing profitability of the farmer. “Although we are still to evaluate quantitatively, profit margin indicators on the ground are already promising,” she says.

Thomas Chikwiramadara and Christopher Chinhimbiti are producing cabbages on their shared plot, pumping water out of a nearby river. One of the advantages for them is the labor-saving component, particularly with weed management. Because water is applied efficiently near the crop, less water is available for the weeds in-between crop plants and plots with drip irrigation are thus far less infested with weeds than plots irrigated with buckets or with flood irrigation.

“This drip system works well especially with weed management,” explains Chinhimbiti. “Now we don’t have to employ any casual labor to help on our plot because the weeds can be managed easily.”

The beginning of a beautiful partnership

In most developing countries, smallholder farmers are the main source of food production, relying heavily on animal and human power. Women play a significant role in this process — from the early days of land preparation to harvesting. However, the sector not only lacks appropriate technologies — such as storage that could reduce postharvest loss and ultimately maximize both the quality and quantity of the farm produce — but fails to include women in the design and validation of these technologies from the beginning.

“Agricultural outputs can be increased if policy makers and other stakeholders consider mechanization beyond simply more power and tractorization in the field,” says Rabe Yahaya, an agricultural mechanization expert at CIMMYT. “Increases in productivity start from planting all the way to storage and processing, and when women are empowered and included at all levels of the value chain.”

In recent years, mechanization has become a hot topic, strongly supported by the German Federal Ministry for Economic Cooperation and Development (BMZ). Under the commission of BMZ, the German development agency GIZ set up the Green Innovation Centers (GIC) program, under which the International Maize and Wheat Improvement Center (CIMMYT) supports mechanization projects in 16 countries — 14 in Africa and two in Asia.

As part of the GIC program, a cross-country working group on agricultural mechanization is striving to improve knowledge on mechanization, exchange best practices among country projects and programs, and foster links between members and other mechanization experts. In this context, CIMMYT has facilitated the development of a matchmaking and south-south learning matrix where each country can indicate what experience they need and what they can offer to the others in the working group. CIMMYT has also developed an expert database for GIC so country teams can reach external consultants to get the support they need.

“The Green Innovation Centers have the resources and mandate to really have an impact at scale, and it is great that CIMMYT was asked to bring the latest thinking around sustainable scaling,” says CIMMYT scaling advisor Lennart Woltering. “This is a beautiful partnership where the added value of each partner is very clear, and we hope to forge more of these partnerships with other development organizations so that CIMMYT can do the research in and for development.”

This approach strongly supports organizational capacity development and improves cooperation between the country projects, explains Joachim Stahl, a capacity development expert at CIMMYT. “This is a fantastic opportunity to support GIZ in working with a strategic approach.” Like Woltering and Yahaya, Stahl is a GIZ-CIM integrated expert, whose position at CIMMYT is directly supported through GIZ.

A catalyst for South-South learning and cooperation

Earlier this year, CIMMYT and GIZ jointly organized the mechanization working group’s annual meeting, which focused on finding storage technologies and mechanization solutions that benefit and include women. Held from July 7–10 July, the virtual event brought together around 60 experts and professionals from 20 countries, who shared their experiences and presented the most successful storage solutions that have been accepted by farmers in Africa for their adaptability, innovativeness and cost and that fit best with local realities.

CIMMYT postharvest specialist Sylvanus Odjo outlined how to reduce postharvest losses and improve food security in smallholder farming systems using inert dusts such as silica, detailing how these can be applied to large-scale agriculture and what viable business models could look like. Alongside this and the presentation of Purdue University’s improved crop storage bags, participants had the opportunity to discuss new technologies in detail, asking questions about profitability analysis and the many variables that may slow uptake in the regions where they work.

Discussions at the meeting also focused heavily on gender and mechanization – specifically, how women can benefit from mechanized farming and the frameworks available to increase their access to relevant technologies. Modernizing the agricultural sector in developing countries in ways that would benefit both men and women has remained a challenge for many professionals. Many argue that the existing technologies are not gender-sensitive or affordable for women, and in many cases, women are not well informed about the available technologies.

However, gender-sensitive and affordable technologies will support smallholder farmers produce more while saving time and energy. Speaking at a panel discussion, representatives from AfricaRice and the Food and Agriculture Organization of the United Nations (FAO) highlighted the importance of involving women during the design, creation and validation of agricultural solutions to ensure that they are gender-sensitive, inclusive and can be used easily by women. Increasing their engagement with existing business models and developing tailored digital services and trainings will help foster technology adaptation and adoption, releasing women farmers from labor drudgery and postharvest losses while improving livelihoods in rural communities and supporting economic transformation in Africa.

Fostering solutions

By the end of the meeting, participants had identified and developed key work packages both for storage technologies and solutions for engaging women in mechanization. For the former, the new work packages proposed the promotion of national and regional dialogues on postharvest, cross-country testing of various postharvest packages, promotion of renewable energies for power supply in storing systems and cross-country scaling of hermetically sealed bags.

To foster solutions for women in mechanization, participants suggested the promotion and scaling of existing business models such as ‘Woman mechanized agro-service provider cooperative’, piloting and scaling gender-inclusive and climate-smart postharvest technologies for smallholder rice value chain actors in Africa, and the identification and testing of gender-sensitive mechanization technologies aimed at finding appropriate tools or approaches.

Farmers flock towards nutritious, orange maize

At seed fair in Masvingo District, Zimbabwe, farmers browse numerous displays of maize, sorghum, millet, groundnuts and cowpeas presented by the seed companies gathered at Muchakata Business Centre.

The event — organized by the International Maize and Wheat Improvement Center (CIMMYT) as part of the R4 Rural Resilience Initiative — is promoting a range of stress-tolerant seeds, but there is a particular rush for the vitamin A-rich, orange maize on offer. Farmers excitedly show each other the distinctive orange packets they are purchasing and in no time all, this maize seed is sold out at the Mukushi Seeds stand.

“I first saw this orange maize in the plot of my neighbor, Florence Chimhini, who was participating in a CIMMYT project,” explains Dorcus Musingarimi, a farmer from Ward 17, Masvingo. “I was fascinated by the deep orange color and Florence told me that this maize was nutritious and contained vitamin A which helps to maintain normal vision and maintain a strong immune system.”

“I would like to grow it for myself and consume it with my family,” says Enna Mutasa, who also purchased the seed. “I heard that it is good for eyesight and skin — and it is also tasty.”

Knowledge transfer through mother trials

Florence Chimhini is one of ten farmers who has participated in the “mother trials” organized as part of the Zambuko/R4 Rural Resilience Initiative since 2018.

These trials were designed in a way that allows farmers to test the performance of six different maize varieties suited to the climatic conditions of their semi-arid region, while also growing them under the principles of conservation agriculture. Using this method, farmers like Chimhini could witness the traits of the different maize varieties for themselves and compare their performance under their own farm conditions.

An important outcome of the mother trials was a growing interest in new varieties previously unknown to smallholders in the area, such as the orange maize varieties ZS244A and ZS500  which are sold commercially by Mukushi Seeds.

“Recent breeding efforts have significantly advanced the vitamin A content of orange maize varieties,” says Christian Thierfelder, a cropping systems agronomist at CIMMYT. “However, the orange color has previously been associated with relief food — which has negative connotations due to major food crises which brought low quality yellow maize to Zimbabwe.”

“Now that farmers have grown this maize in their own mother trial plots and got first-hand experience, their comments are overwhelmingly positive. The local dishes of roasted maize and maize porridge are tastier and have become a special treat for the farmers,” he explains.

“Though not as high yielding as current white maize varieties, growing orange maize under climate-smart conservation agriculture systems can also provide sustained and stable yields for farm families in Zimbabwe’s drought-prone areas.”

Addressing micronutrient deficiency

In Zimbabwe, at least one in every five children suffers from ailments caused by vitamin A deficiency, from low levels of concentration to stunting and blindness. The vitamin is commonly found in leafy green vegetables, fruits and animal products — sources that may be unavailable or unaffordable for many resource-poor households.

Staple maize grain, however, is often available to smallholder families and thus serves as a reliable means through which to provide additional micronutrient requirements through conventional biofortification. This allows people to improve their nutrition through the foods that they already grow and eat every day, says Lorence Mjere, a seed systems officer at HarvestPlus Zimbabwe.

The beta-carotene in orange maize gives it its distinctive orange color and provides consumers with up to 50% of their daily vitamin A requirements.

“Orange maize addresses hidden hunger in family diets by providing the much-needed pro-vitamin A which is converted to retinol upon consumption,” explains Thokozile Ndhlela, a maize breeder at CIMMYT. “In doing so, it helps alleviate symptoms of deficiency such as night blindness and poor growth in children, to name just a few.”

The success of the recent seed fairs shows that provitamin A maize is gaining momentum among smallholder farmers in Masvingo and its continued promotion will support all other efforts to improve food and nutrition security in rural farming communities of southern Africa.

A catastrophe avoided

There are decades when nothing happens and weeks when decades happen. So goes the old saw. In the social sciences, these “weeks” are often referred to as critical junctures. They are moments when the old rules of the game — the long-established ways of doings things — go out the window and new patterns begin to emerge. The breadbasket states of northwestern India seem to be having one of those weeks.

After years of research and advocacy that appeared to be making little headway, researchers at the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR) are seeing a sudden and dramatic increase in the adoption of some of the technologies and techniques they have long argued are necessary in this region, including direct-seeding of rice, crop diversification and the adoption of Happy Seeder technology.

A case of unintended consequences

In March 2020 the Indian government decreed a national lockdown in response to the COVID-19 crisis. This triggered the largest internal migration since partition, as millions of migrant workers and day laborers scrambled to return to their home villages. Estimates suggest that up to 1 million workers left the northwestern states of Haryana and Punjab alone.

Agriculture in the region is dominated by the labor- and input-intensive production of rice and wheat in rotation. This system is the most productive per hectare in India, but it is also extremely sensitive to external shocks. The success of both the rice and wheat crop depend on the timely transplantation of rice in mid-June.

As the results of a recently published study demonstrate, delays in this schedule can have devastating downstream effects not only on rice and wheat yields, but on regional air quality too. Models of the worst-case delay scenario predicted a total economic loss of nearly $1.5 billion. Moreover, they predicted that, if no action were taken, up to 80% of rice residue would be burned later in the autumn, when cooler conditions contribute to seasonally poor air quality.

Such an exacerbation of the region’s air pollution would be dire under normal conditions. During a global pandemic of a primarily respiratory illness, it could be devastating.

Fortunately, solutions and technologies that CIMMYT researchers had been studying for decades, along with ICAR, Punjab Agricultural University (PAU) and other national partners, promised to help ward off the worst effects of the crisis. The adoption of direct-seeding technology could help reduce the labor-intensiveness of rice production, crop diversification could minimize the economic impacts of the crisis, and the use of Happy Seeder technology could alleviate the practice of residue burning.

Decades of work pay off

The study, co-authored by researchers at CIMMYT, ICAR and the International Rice Research Institute (IRRI), relied on a sophisticated ex ante model of four different rice-transplanting delay scenarios. It is published in the November 2020 issue of Agricultural Systems.

However, given the time-sensitivity and high-stakes of the issue, the lead researchers did not wait for the articles publication to press their case. Earlier this year they circulated their initial findings and recommendations to policymakers via their national partners. Notably, after receiving a one-pager summarizing these, the Chief Minister of Punjab released a video address echoing their points.

“Policymakers realized the need for these kinds of solutions,” says Balwinder Singh, a CIMMYT scientist and lead author of the paper. They then moved quickly to incentivize their adoption through various mechanisms, such as subsidizing direct-seeding drills and ensuring the timely availability of machines and other inputs.

This year, 500,000 hectares were converted to direct seeding, explains M.L. Jat, a principal scientist at CIMMYT. This represents 34% more area converted in 2020 alone than in the previous 10 years. Additionally, 330,000 hectares were converted to other crops, principally cotton, maize and legumes.

Singh and Jat have been carrying out a multi-year survey to assess farmer willingness to adopt Happy Seeder technology and have documented a drastic increase in farmer interest in the technology during 2020. For Jat, this highlights the power of partnerships. “If you don’t include your partners from the beginning, they will not own what you say,” he argues.

Such changes are to be celebrated not only as an important response to the current labor shortage, but also as key to ensuring the long-term sustainability of agricultural production in the region, having important implications for the stewardship of water resources, air pollution and soil health.

“Policies encouraging farming practices that save resources and protect the environment will improve long-term productivity and sustainability of the nation,” says S. K. Chaudhari, deputy director general for Natural Resource Management at ICAR.

Warding off catastrophe

Although the agricultural cycle is not yet over, and early data are still partial, Singh and Jat estimate that thanks to the dramatic adoption of alternative agricultural practices this year, their worst-case estimates have been avoided. Given the rapid response from both policymakers and farmers, the real-world effects of the COVID-19 labor crisis are likely closer to the mid-range severity scenarios of their analysis. Indeed, early estimates predict no rice yield losses and minor-to-no wheat yield losses over baseline. For the researchers, the relief is palpable and the lessons couldn’t be clearer.

“These technologies were there for decades, but they were never appreciated because everything was normal,” says Jat. “This clearly indicates a need for investment in the technology and the research. You may encounter a problem at any time, but you cannot generate the technology overnight.”

Digital revolution can transform agri-food systems

A digital transformation is changing the face of international research for development and agri-food systems worldwide. This was the key takeaway from the 4th annual CGIAR Big Data in Agriculture Convention held virtually last month.

“In many countries, farmers are using data to learn about market trends and weather predictions,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT), in a video address to convention participants. “But many still do not have access to everything that big data offers, and that is where CIMMYT and partners come in.”

As a member of CGIAR, CIMMYT is committed to ensuring that farmers around the world get access to data-driven solutions and information, while at the same time ensuring that the data generated by farmers, researchers and others is used ethically.

According to CGIAR experts and partner organizations, there are four key areas with the potential to transform agriculture in the next 10 years: data, artificial intelligence (AI), digital services and sector intelligence.

Key interventions will involve enabling open data and responsible data use, developing responsible AI, enabling and validating bundled digital services for food systems, and building trust in technology and big data — many of which CIMMYT has been working on already.

Harnessing data and data analytics

Led by CIMMYT, the CGIAR Excellence in Breeding (EiB) team have been developing the Enterprise Breeding System (EBS) — a single data management software solution for global breeding programs. The software aims to provide a solution to manage data across the entire breeding data workflow — from experiment creation to analytics — all in a single user-friendly dashboard.

CIMMYT and partners have also made significant breakthroughs in crop modelling to better understand crop performance and yield gaps, optimize planting dates and irrigation systems, and improve predictions of pest outbreaks. The Community of Practice (CoP) on Crop Modeling, a CGIAR initiative led by CIMMYT Crop Physiologist Matthew Reynolds, aims to foster collaboration and improve the collection of open access, easy-to-use data available for crop modelling.

The CIMMYT-led Community of Practice (CoP) on Socio-Economic Data continues to work at the forefront of making messy socio-economic data interoperable to address urgent and pressing global development issues in agri-food systems. Data interoperability, one of the foundational components of the FAIR data standards supported by CGIAR, addresses the ability of systems and services that create, exchange and consume data to have clear, shared expectations for its content, context and meaning. In the wake of COVID-19, the world witnessed the need for better data interoperability to understand what is happening in global food systems, and the CoP actively supports that process.

Improving data use and supporting digital transformation

In Ethiopia, the MARPLE (Mobile And Real-time PLant disEase) diagnostic kit — developed by CIMMYT, the Ethiopian Institute of Agricultural Research (EIAR) and the John Innes Centre (JIC) — has helped researchers, local governments and farmers to rapidly detect diseases like wheat rust in the field. The suitcase-sized kit cuts down the time it takes to detect this disease from months to just 48 hours.

In collaboration with research and meteorological organizations including Wageningen University and the European Space Agency (ESA), CIMMYT researchers have also been developing practical applications for satellite-sourced weather data. Crop scientists have been using this data to analyze maize and wheat cropping systems on a larger scale and create more precise crop models to predict the tolerance of crop varieties to stresses like drought and heatwaves. The aim is to share the climate and weather data available on an open access, user-friendly database.

Through the AgriFoodTrust platform — a new testing and learning platform for digital trust and transparency technologies – CIMMYT researchers have been experimenting with technologies like blockchain to tackle issues such as food safety, traceability, sustainability, and adulterated and counterfeit fertilizers and seeds. Findings will be used to build capacity on all aspects of the technologies and their application to ensure this they are inclusive and usable.

In Mexico, CIMMYT and partners have developed an application which offers tailored recommendations to help individual farmers deal with crop production challenges sustainably. The AgroTutor app offers farmers free information on historic yield potential, local benchmarks,  recommended agricultural practices,  commodity price forecasting and more.

Stepping up to the challenge

As the world becomes increasingly digital, harnessing the full potential of digital technologies is a huge area of opportunity for the agricultural research for development community, but one that is currently lacking clear leadership. As a global organization already working on global problems, it’s time for the CGIAR network to step up to the challenge. Carrying a legacy of agronomic research, agricultural extension, and research into adoption of technologies and innovations, CGIAR has an opportunity to become a leader in the digital transformation of agriculture.

Currently, the CGIAR System is coming together as One CGIAR. This transformation process is a dynamic reformulation of CGIAR’s partnerships, knowledge, assets, and global presence, aiming for greater integration and impact in the face of the interdependent challenges facing today’s world.

“One CGIAR’s role in supporting digitalization is both to improve research driven by data and data analytics, but also to foster the digitalization of agriculture in low and lower-middle income countries,” said CIMMYT Economist Gideon Kruseman at a session on Exploring CGIAR Digital Strategy at last month’s Big Data convention.

“One CGIAR — with its neutral stance and its focus on global public goods — can act as an honest broker between different stakeholders in the digital ecosystem.”

Breaking Ground: Andrea Gardeazábal transforms data into meaningful information

Andrea Gardeazábal has many titles — Monitor, Evaluation and Learning Manager, ICT for Agriculture — but the core of what she does is knowledge management. She merges monitoring, evaluation, accountability and learning (MEAL) with information communication technologies (ICT) to transform data into something meaningful.

A political scientist by training, Gardeazábal knows the power of data and statistics. As she began working on ICT-for-development projects in the field, she observed a lack of understanding of ICT and how the development sector could take advantage of these tools.

“I knew this was progressing very fast; that this was the future. Everyone was talking about ICT and the future with the internet of things, and social media was just getting started,” she said. So she asked herself, how could the development sector take advantage of these new technologies?

Gardeazábal was working on projects bringing computers to rural areas in Colombia, which did not have internet connection or electricity. The problem could not be solved simply with a machine. She wanted to understand how to use ICT for development in a meaningful way. This triggered an interest in MEAL, to understand how ICT benefits the development sector, or does not, and to reintegrate that information into project design and impact.

After working in ICT for civil participation, education and microfinance, she joined CIMMYT with the mission to understand ICT for agriculture. Now she merges ICT tools with MEAL, leading the design, development and operation of systems for data collection, data cleaning, data analysis and data visualization with the Integrated Development program’s projects in Colombia, Guatemala and Mexico.

Ensuring intended results

Monitoring, learning, accountability and evaluation is crucial to ensure CIMMYT delivers on its objectives. Monitoring means ensuring that operations in the field are happening as planned. Rather than waiting until the end of the project when the donor asks for a report, Gardeazábal’s team monitors operations in the field on a quarterly or yearly basis. The team, both in the field and at headquarters, uses this data to check that the project is achieving what was intended and make interventions or adjustments if necessary.

Evaluation looks at project results and evidence. The team collects evidence for every single data point that they have, and then evaluates that evidence for impact and results in the field. This data is not only related to yield increase, but includes sustainable production, capacity development, and adequate technology adaptation and adoption processes.

Accountability is transparency with funders, so that everyone involved in a project is accountable for the processes, decisions and impact. CIMMYT is able to show progress through a transparent relationship with funders.

Learning happens after the team collects information, produces results evaluations, and understands what was done well and where the process had to be redirected. This information can then inform design of new projects or project phases. “We use the data and analysis of each project to redesign or modify our plans for the next project or even what kinds of projects we want to conduct,” Gardeazábal said.

What ICT can offer

In the past, a MEAL team would collect data from a representative sample at the start of the project, then go back to the office and analyze that data. At the end of the project, the team would complete the same exercise, to see the difference from what they gathered at the beginning.

With ICT tools, researchers are able to gather and analyze robust data more quickly and can communicate efficiently with the beneficiaries of a project throughout its course. Artificial intelligence and machine learning algorithms can help in understanding large sets of data so that this information can strengthen and streamline the MEAL process and project impact.

“We don’t need to wait until the end of the project for the results in the field or to have a sense of what the farmers are saying and achieving. We have a lot of tools, from the ICT side, that help make monitoring and evaluation more efficient,” Gardeazábal explained.

An international award recognized some of these ICT tools earlier this year. Gardeazábal formed part of the winning team with members from the Alliance of Bioversity International and CIAT and the International Institute for Applied Systems Analysis (IIASA) working on groundbreaking data systems and tools that help over 150,000 farmers in Mexico.

The team tracked over 500 variables over different farming plots and analyzed them with geographic, weather and market data to help identify the best management practices for each plot. This information — including historic yield potential, local benchmarks, windows of opportunity, recommended agricultural practices and commodity price forecasting — is available to farmers through an app called AgroTutor (Android, iOS).

The importance of an enabling environment

However, Gardeazábal cautions against the idea that technology on its own is going to end poverty or increase food security.

“ICT is a vehicle for innovation in agriculture. Just having an app in the field is not enough to generate the change that we are actually looking for. You need an enabling environment, a network, engagement of the farmers and the buy-in of scientists to take advantage of ICT tools.”

From drones and satellite imagery to artificial intelligence, ICT tools can help CIMMYT carry out its mission by streamlining the data gathering and analytics processes.

However, this work is not done in isolation from the environment surrounding it. CIMMYT does not only work on increasing yields, but also manages resources and local networks in efficient ways. Teams must monitor data on air quality, water use and efficient information flows, analyze this data, and then return to the field with recommendations for the most sustainable production within integrated agri-food systems.

Reflections on resilience

Approaching Ward 6 in Mwenezi, southern Zimbabwe, tracts of empty fields around homesteads on either side of the road signal the end of harvesting for the 2019/20 farming season. Farmers have stored away maize fodder on tree branches or inside the family compounds.

At one of the homesteads in the village of Chikwalakwala A, ten farmers are gathered while agricultural extension officers weigh grain and legume samples. They are participating in mother trials from the International Maize and Wheat Improvement Center (CIMMYT), using improved farming practices and drought-resilient seed varieties. This is one of the eight villages in Ward 6 where CIMMYT has established demonstration sites, as part of the Zambuko Livelihoods Initiative, supported by the United States Agency for International Development (USAID).

“Most of us here were born and raised in this ward, helping our parents with farming activities and continuing with farming when we finally had our own families,” farmer Tevera Romichi explains. However, the dry spells, high temperatures and erratic rainfall have become increasingly disturbing for him in recent years. “It became difficult to determine when we would receive enough rain to plant our crops without risking long dry spells,” he says.

The onset of rains in Mwenezi has shifted over the years, from late September to the end of October or early November. With most families in the district depending on agriculture for their livelihoods, the adverse change in climatic conditions has compromised food security. These farmers grow crops such as millet, sorghum and groundnut.

Clemence Hlungwane, another farmer participating in mother trials, further explains how traditional practices of repeated tillage with ox-drawn ploughs weakened the soil structure, exposing it to soil erosion and loss of fertility. “These soils have been overused without any thought of how to replenish all the nutrients that were found in the soil in past years,” he says. The result for families like Hlungwane’s were poor germination, susceptibility to pests and diseases and poor yields.

Being smart in the field

The introduction of climate-smart technologies by CIMMYT provided a channel through which mother-trial farmers in Ward 6 could explore alternative farming practices in a sustainable way while adapting to climate-induced risks. The principles of conservation agriculture, which encourage the preservation of soil moisture and nutrients, underpinned the technologies introduced by CIMMYT.

Initially, mother trial farmers expressed mixed feelings when the CIMMYT team and the Agricultural Extension and Technical Services (AGRITEX) officials took them through the process of establishing the demonstration plots. “It seemed like a lot of work,” Charleton Midzi recalls. “There was a lot of measuring, pegging and marking the demonstration plots but we soon realized that this would be important when planting the small grains and legumes.”

“At the same time, I was curious to see how ploughing with a ripper would help the soil and crops along with the practice of mulching,” Midzi says. “Where mulch was applied, the moisture was well preserved, and the crops looked much healthier and vibrant than in portions without mulch.” Another important lesson was understanding the importance of record keeping for planting dates, harvesting dates and rainfall records to inform the next season. In addition, good agronomy practices such as spacing, correct application of nutrients and use of pesticides contributed to the successful production at the demonstration plots.

“We no longer waste inputs,” says Caleb Matandare, a farmer in the village of Chikwalakwala C. “Being smart in the field means applying the correct amount of fertilizer using the measuring cups provided and keeping a record of the suitable amount for the crop.”

By the end of the season, the mother farmers observed the evident difference in the higher quality of the millet and sorghum planted on the conservation agriculture plots, compared to the conventional plots. From the yields of sorghum, millet and cowpeas, Matandare’s family of 13 are guaranteed enough diverse and nutritious food, particularly in the “lean season,” the period between harvests.

Baby-trial farmers eager to learn

Since the establishment of the mother trials in Ward 6, several farmers witnessing the advantages of producing under conservation agriculture and using drought-resilient varieties are keen to adopt the improved technologies.

Margaret Mapuranga shares how her neighbor inquired about the legume crops. “I explained to her how lablab, velvet bean and cowpeas fix nitrogen in the soil, which will be useful for the grain crops in the next season. She would like to try out the same in her own field in the coming season.” Mapuranga is confident that she can promote these sustainable practices with farmers selected for the baby trials in her village.

The coming 2020/21 season looks promising as more farmers in Ward 6 adopt the improved technologies. Mother-trial farmers are eager to expand conservation agriculture practices to other portions of their land as a safeguard against climate risks. For them, the ability to share the climate-smart technologies promoted by CIMMYT is an empowering process that will transform agriculture in the ward and beyond.
