Partnership approach to maize development praised in new study

Written by Sarah McLaughlin on . Posted in Publications.

Using data from 1995-2015, an empirical study from the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA), led by Vijesh Krishna, CIMMYT Lead Adoption – Impact Economist, has estimated the economic benefits of new varieties in 18 major maize-producing countries in sub-Saharan Africa.

Kevin Pixley, Deputy Director General for Research (Breeding and Genetics), a.i., and Director of the Genetic Resources Program, said, “This was not easy due to the challenges of gathering and analyzing complex data, but it’s a very important milestone for CIMMYT. Peer review in a highly respected journal is a gold standard that gives external critique and endorsement to the impact assessment methods used and estimates reported for CIMMYT and IITA’s work with partners in Africa.”

Around 60 percent of the 1,345 maize varieties released in this twenty-year period had a known CGIAR parentage.

Approximately 34 percent of the total maize area in 2015 was cultivated with CGIAR-related maize varieties from 1995 onwards, equivalent to 9.5 million hectares (ha); 13 percent of the maize area was under CGIAR-related varieties released before 1995.

The new maize varieties hold an economic benefit for the region, with an estimated value of US $1.1-1.6 billion in 2015 equally attributed to CGIAR, public-sector national research and extension programs, and private sector partners. With maximum annual investment in CGIAR maize breeding sitting at US $30 million, the estimated benefit-cost ratio for investment was between 12:1-17:1, depending on the underlying assumptions.

“This paper is a valuable contribution to literature on impact assessment, highlighting the real challenges and approaches to quantify impact of work that is a collaboration among many,” continued Pixley. “Both the methodologies and impact estimates will be valuable to researchers and funders of plant breeding programs.”

Study explores how to reduce GHG emissions while supporting food security through nitrogen management

Written by Sarah McLaughlin on . Posted in Publications.

Use of fertilizer nitrogen (N) in farming is essential for food production but also contributes to climate crisis through GHG emissions. Synthetic nitrogen fertilizer accounts for 2.4 percent of global emissions, while its supply chain accounts for 21.5% of the annual direct emissions from agriculture.

One potential solution for developing appropriate N management strategies is yield-scaled nitrous oxide (N₂O) emission (YSNE), which has been recognized for its potential to balance food security and mitigate emissions. Improving understanding and use of YSNE under various field conditions is an essential part of widespread adoption of this approach.

Scientist working in the Sustainable Agrifood Systems (SAS) program at the International Maize and Wheat Improvement Center (CIMMYT) together with Hawassa University, Ethiopia and Landcare Research, New Zealand  assessed the relationship between N inputs and YSNE with published results and identified response patterns of YSNE to N inputs based on 1,800 observations from maize, rice and wheat crops at global scale.

A positive relationship between N inputs and YSNE was evidenced in more than 60% of the dataset across all three crops, while a small proportion had an optimum N rate that minimized YSNE. Type of crop, annual mean temperature and soil N content affected the background yield-scale N₂O emission with higher soil temperature and N content leading to higher BYSNE. The analyses suggest that YSNE can be reduced by increasing yields, by reducing N₂O emissions and both by increasing yields and reducing N₂O emissions. The results of this study suggest appropriate N management strategies, yields, and N2O emissions.

Decolonization should extend to collaborations, authorship and co-creation of knowledge

Written by Sarah McLaughlin on . Posted in In the media.

In an article forming part of a series on decolonizing the biosciences, Sieglinde Snapp, Director of the Sustainable Agrifood Systems (SAS) program at the International Maize and Wheat Improvement Center (CIMMYT), explores how to improve inclusivity in scientific research.

The Global South, where work is more locally contextualized and applied, can end up excluded due to the existing reward structure, which rewards pure science first, then applied research and outreach.

As part of her decolonization toolkit, Snapp recommends ways to champion inclusivity, such as following a participatory research approach to create new knowledge, advocacy through authorship, and using alternative indices for performance evaluations.

Young CIMMYT scientist receives 2022 Japan Award for global research to combat wheat aphids

Written by Mike Listman on . Posted in News.

“To meet expected wheat demand for 2050, production will need to double, which means increasing harvests nearly 70 kilograms per hectare each year,” said Leonardo Crespo-Herrera, CIMMYT wheat scientist and 2022 Japan Award recipient. “Breeding will be a major contributor, but better agronomic practices and policies will also be critical.” (Photo: CIMMYT)

International science to save wheat — a crucial food grain for 2.5 billion of the world’s poor — from a rising tide of insect pests known as aphids was lauded on November 22 with the 2022 Japan International Award for Young Agricultural Researchers (the Japan Award).

The 2022 Japan Award recognized novel breeding approaches to identify and select for genetic resistance in wheat to two species of aphids that cause wheat grain losses reaching 20% and whose rapid spread is propelled by rising temperatures.

Aphid resistant wheat can contribute to more sustainable food production, protecting farmers’ harvests and profits, while reducing the need to use costly and harmful insecticides, said Leonardo Crespo-Herrera, bread wheat improvement specialist for the International Maize and Wheat Improvement Center (CIMMYT) and one of the three 2022 Japan Award recipients.

“In addition to genetic yield potential, CIMMYT wheat breeding focuses on yield stability, disease resistance, and nutritional and end-use quality,” Crespo-Herrera explained. “Adding another target trait — aphid resistance — makes wheat breeding much more challenging.”

Efficient and effective field testing to confirm the genetics

Crespo-Herrera and his CIMMYT colleagues managed to identify and characterize genome segments responsible for aphid resistance in wheat and its near relatives, as well as running innovative field tests for a set of elite wheat breeding lines that were predicted to carry that resistance.

“With the aphid species called the greenbug, its feeding causes yellowing and necrotic spots on wheat, so we could actually measure and score wheat plants in plots that we deliberately infested with the aphids, keeping the resistant lines and throwing out the susceptible ones,” said Crespo-Herrera.

For the other species, the bird cherry-oat aphid, the only visible feeding damage is when the plants become stunted and die, so Crespo-Herrera and colleagues instead measured biomass loss and reduced growth in 1,000 artificially infested wheat lines, identifying a number of lines that had low scores for those measurements. Given that the lines tested came from a set that had already shown resistance to the greenbug, some of the successful lines feature resistance to both aphid species.

For the bird cherry-oat aphid, in two years of additional field tests, Crespo-Herrera and his team found that aphid populations were lower in plots sown with resistant wheat lines. “The experiments included remote sensing measurements that identified certain spectral signatures correlated with aphid populations; this may help us to assess resistance in future field trials.”

The researchers also found that a cutting-edge approach known as “genomic prediction” provided good estimations regarding promising, aphid-resistant wheat breeding lines.

Motivating young researchers in research and development

Established in 2007, the Japan Award is an annual prize organized by the Agriculture, Forestry and Fisheries Research Council (AFFRC) of Japan’s Ministry of Agriculture, Forestry and Fisheries (MAFF) and supported by the Japan International Research Center for Agricultural Sciences (JIRCAS). Awardees receive a $5,000 cash prize.

In an excerpt of an official note regarding Crespo-Herrera’s research, those agencies said  “…This study has been highly evaluated for developing (wheat) lines that have been distributed worldwide for use in wheat breeding, and the methods of this study have been applied to develop varieties with resistance mechanisms against various kinds of insects, not only aphids.”

Crespo-Herrera thanked JIRCAS and MAFF for the award. “I feel honored to have been selected.”

In early September 2022, the International Maize and Wheat Improvement Center (CIMMYT) Director General Bram Govaerts made a brief visit to Ethiopia — his first since taking on the role in 2021. Over two days in Addis Ababa he met with a number of government representatives, donors and partners, including the Agricultural Transformation Institute (ATI), the Ethiopian Institute for Agricultural Research (EIAR), Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH, and The Development Fund.

Discussions centered around South-South cooperation and how CIMMYT’s strategic priority to transform agrifood systems can support efforts to improve the livelihoods of resource poor farmers in Ethiopia and national food security. Through longstanding collaboration with local partners, CIMMYT has continued to support the country through maize and wheat germplasm supply, joint technology generation and demonstrations at scale, but the visit provided an opportunity to identify shared priorities and key areas for partnership.

Supporting a plan for self-sufficiency

In a meeting with representatives from the ATI and EIAR, the CIMMYT delegation were briefed on the elements of the Government of Ethiopia’s ten-year development plan and its targets to achieve food self-sufficiency by 2030, with commercialization, advocacy on land ownership, and financial sector reform emerging as key areas of focus.

In terms of policy change, explained ATI Director General Mandefro Nigussie, there are ten core agendas that the government has set and plans to implement in the coming years. These include land governance and advisory; public-private partnership; marketing and infrastructure; and digital agriculture. The continued need for capacity building emerged as a key concern, as high staff turnover has meant many of those trained by CIMMYT previously had now left their posts.

Govaerts thanked ATI and EIAR for their collaboration so far, noting that this would surely continue as CIMMYT planned to double engagement, collaboration, production and partnerships in the coming years. Addressing the concerns raised around capacity building, particularly the training of experts, he explained that training opportunities had been limited in the last two years because of the COVID-19 pandemic and budget constraints, but capacity building for research and extension was included in the list of future action points, including a ministerial visit to CIMMYT offices in either Mexico or India.

The discussions were productive, and participants reached agreement on several other points, including collaboration on the establishment of a One Stop Shop by ATI; supporting EIAR’s data warehouse development that will provide farmers with access to an agronomy advisory services hotline; and supporting the breading of wheat for heat tolerance and Ethiopia’s irrigated wheat initiative.

Strengthening collaboration

Govaerts later met with several representatives from The Development Fund, including Country Director for Ethiopia Ulf Flink, to discuss opportunities for strengthening partnerships for greater impact. The Development Fund’s Ethiopian portfolio has evolved over four decades from supporting relief work by one Tigrayan organization to supporting multiple projects with several organizations in Tigray and Afar, with a focus on socio-economic development to alleviate poverty, and improve food security and natural resource management in dryland areas.

While the organization has recently encountered challenges in Tigray, with several programs disrupted by instability, Flink noted that the implementation of The Development Fund’s collaborative projects with CIMMYT are progressing well and pointed out opportunities to scale-up joint operations in the region, where more than 5,000 farmers have been supported so far.

Govaerts thanked The Development Fund for the strong collaboration so far and emphasized CIMMYT’s need for continued strategic partnership in South-South collaboration that can make a difference to smallholders in the country. He also pointed to CIMMYT’s aim of doubling impact and coverage, highlighting that changes in partners’ thinking and ways of intervening could be opportunities to strengthen collaboration with The Development Fund.

Cognizant of the limitations imposed by major challenges such as funding modalities — which are shifting towards humanitarian rather than development assistance — and the increasing price of mechanization, meeting participants were able to agree on a number of action points to support future collaborative work. These include continued support to project implementation in Tigray when the security situation allows; exploring opportunities to strengthen collaborations in other countries such as Malawi; and supporting research-based advocacy at both regional and zonal levels.

Additionally, CIMMYT will share its methodology for Integrated Development and research-based humanitarian development support, and work with The Development Fund to provide improved crop varieties and grain with smallholder famers in drought- and conflict-affected areas where projects are being implemented.

Analyzing 25 years of maize supply and demand in the Global South

Written by Sarah McLaughlin on . Posted in Publications.

Over the next 10 years, maize is due to become the most widely grown and traded crop globally and is already the cereal with the highest production volume. Its versatility offers multiple purposes – as a livestock feed in both developed and developing economies, as a key component of human diets in several low- and middle-income countries in sub-Saharan Africa, Latin America and Asia, and for an array of non-food uses worldwide.

To analyze the changes in the supply and demand for maize in the last 25 years, scientists at the International Maize and Wheat Improvement Center (CIMMYT) conducted a review of maize production, consumption, and international trade.

The study primarily focused on the Global South, where intensive work is being done to transform the agrifood systems in which maize plays a key role. Through scientific advancements over time, maize yields have increased, although heterogeneously, while the area under cultivation of maize has also expanded due to sharply growing demand.

Research determined that this transformation offers opportunities for investment in maize research and development (R&D) to determine ways that production and productivity can be significantly improved without expanding maize area or creating negative impacts on the environment.

Sustainability, quality concerns take center stage at Cereals & Grains 22

Written by Sarah McLaughlin on . Posted in In the media.

At the Cereals & Grains 22 conference, programming focused on Innovating the Future of Foodand the challenges faced by the grain industry, particularly relating to the effects of climate change on maize and wheat yields and quality.

“Agriculture systems are sensitive to climate change because they are dependent on stable, long-term conditions to determine productivity, quality and yields,” said Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT) and the conference’s keynote speaker. “Farmers are struggling to cope with climate risks and their ability to meet rising global food demands.”

Breeding maize and wheat with traits resistant to the consequences of climate change, such as flooding, drought, and heat, moving growing areas to amenable climates, and promoting soil health and biodiversity were all proposed as solutions to address the challenges highlighted by Govaerts.

One of the biggest challenges facing the world today is how to balance a healthy diet for humans with agricultural production that is good for the environment. At the International Maize and Wheat Improvement Center (CIMMYT), scientists work closely with farmers to achieve these aims and contribute towards food security, as well as improving their livelihoods and nutrition.

In an opening keynote at Cereal & Grains 22 titled Risk Mitigation in the Food Chain, Bram Govaerts, Director General a. i. of CIMMYT, focused on the organization’s work towards a world with resilient agrifood systems that protect biodiversity.

Govaerts explored the sensitivity of agricultural systems to the impacts of climate change, which in turn affects farmers’ ability to successfully produce crops and their capacity to meet rising global demand for food. However, agriculture itself is not immune from contributing towards climate change, currently accounting for 24% of greenhouse gas (GHG) emissions.

The effects of climate change are not the only pressure on agrifood systems, with other system shocks such as COVID-19 and conflict causing disruption to production and yields, prices, and supply chains, said Govaerts. For example, the current Ukraine crisis, which has heavily affected wheat imports and exports, underscores the need for long-term solutions to stabilize global food security. The encroaching cost of living crisis is adding further challenges to an already delicate situation, and hunger is predicted to increase across the Global South.

Investing in solutions

Research and development (R&D) has an essential role to play in addressing this crisis. Evidence shows that for every $1 USD invested in anticipatory action to safeguard lives and livelihoods, up to $7 USD can be saved by avoiding losses in disaster-affected communities. Simply put, proactive investment in agricultural science will save money in the long run by solving problems before they reach critical point.

CIMMYT’s R&D projects focus on extensive research on climate change adaptation and mitigation in maize and wheat-based production systems, helping smallholder farmers adapt to climate shocks and to raise and maintain yields in profitable and sustainable ways, and on capacity building for stakeholders in the development and application of new technologies.

Scientists are also harnessing the power of genebanks and breeding, focusing on safeguarding, characterization, and use of biodiversity to identify characteristics of seeds for genetic gain, adaptation to climate change, and better nutritional quality. This means farmers can access more and better seeds that respond to agrifood needs.

These innovations are only as effective as their level of adoption, which is why CIMMYT works closely with actors at all levels of agrifood systems.

Climate science at work in Africa

Govaerts shared examples of CIMMYT’s climate change adaptation and mitigation work include the introduction of drought-tolerant maize in Zimbabwe, which yielded more than 0.6 t/ha more than previous varieties. This equates to $240 USD more income per hectare, which provides nine months’ worth of additional food security at no extra cost.

In Malawi, drought-tolerant maize varieties planted under conservation agriculture yielded 66% more than non-tolerant varieties planted under conventional tillage. Farmers harvested more maize while spending on average 35-45 fewer days working in the field.

There is also an increase in popularity for stress-tolerant wheat varieties in Ethiopia, such as Danda’a, Kakaba, Kingbird and Pavon 76.

Scientists have also combined tropical fall armyworm (FAW)-resistant maize germplasm, from Mexico, with elite stress resilient germplasm developed in sub-Saharan Africa to successfully breed three FAW-tolerant elite maize hybrids. This is addressing the serious threat of FAW to maize production in eastern and southern Africa.

Transformation through partnership working

Following an Integrated Agrifood Systems Approach (IASA) has given CIMMYT significant edge by building effective partnerships with the public and private sector. Collaboration on responsible sourcing with Kellogg’s and Grupo Bimbo, as well as a new three-year partnership with Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and Grupo Modelo to encourage water-conserving farming practices, will contribute to a one-system approach.

More than 18 million farmers worldwide benefit through CIMMYT’s improved maize and wheat system farming practices. With so much at stake for the entire world, CIMMYT has no plans to stop now.

Agriculture for Peace platform launches at Borlaug Dialogue

Written by Sarah McLaughlin on . Posted in Features.

Events of the past year have underscored the correlation of food supply chains, and weaknesses that need to be addressed. Tackling threats to global food security caused by COVID-19, conflict, and climate change require joint action and long-term commitments, with approaches based on partnerships, collaborative research and information sharing, and involvement from all actors within agrifood systems.

These topics and potential solutions were integral to the 2022 Norman E. Borlaug International Dialogue, hosted between October 18-20, 2022. With a theme of Feeding a Fragile World and overcoming shocks to the global food system, seminars and workshops explored scalable solutions for adaptation and mitigation to limit global warming and meet the UN Sustainable Development Goals (SDGs).

One event which proposed a solution to these challenges was Agriculture for Peace (Ag4Peace): A Call for Action, which marked the official launch of a platform aiming to support national food and agriculture strategies.

The initiative was founded by seven partners: Norman Borlaug Foundation, the International Maize and Wheat Improvement Center (CIMMYT), Cornell University College of Agriculture and Life Sciences, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Livestock Research Institute (ILRI), the International Rice Research Institute (IRRI) and Texas A&M University.

During the event, two additional collaborators were announced: World Wide Fund for Nature and Inter-American Institute for Cooperation on Agriculture (IICA).

The Ag4Peace concept

Ag4Peace is built on the understanding that without peace there is no food, and without food there is no peace. Conflicts and violence severely disrupt agricultural processes and limit access to food, which in turn forces people to take increasingly perilous actions as they attempt to secure their lives and those of their families. High food prices and hunger cause instability, migration, and civil unrest as people become more desperate.

Using a collaborative approach, partners will design holistic strategies that encompass the multi-faceted nature of agrifood systems and their interconnections with nature, nutrition, and livelihoods. This requires broad-based collaborations, so the Ag4Peace partners welcome other institutions, private sector, and non-governmental organizations that share their aspirations to join them.

Partners are co-constructing the Cross-Sector Collaboration to Advance Resilient Equitable Agrifood Systems (CC-AREAS), the first operational plan for the platform. This is a 10-year proof-of-concept program that applies a holistic, systems approach to achieve resilient agrifood systems and accelerate development of the circular bioeconomy in five low- and middle-income countries (LMICs) that are increasingly exposed to food security risks due to climate change and reliance on imported staple foods.

They will support national efforts to upgrade agrifood systems, adopt regenerative agriculture and climate-smart strategies, expand the circular bioeconomy, and achieve nutrition and food security goals.

In all aspects of the initiative (science, planning, implementation, and evaluation), participation priority will be given to small-scale farmers, women, and socially diverse groups, which will maximize positive outcomes and ensure inclusivity.

Benefits for farmers, communities, value chain participants, consumers, and ecosystems will be demonstrated throughout to encourage adoption and continued use of improved technologies and practices and demonstrate effectiveness.

Partner support for Ag4Peace

After the concept was introduced by Bram Govaerts, Director General of CIMMYT and recipient of the 2014 Norman Borlaug Award for Field Research and Application, a roundtable discussion with a diverse panel of experts began.

Speakers included Manuel Otero, Director General of the Inter-American Institute for Cooperation on Agriculture (IICA), Hon. Sharon E. Burke, Global Fellow of Environmental Change and Security Program at the Wilson Center, Per Pinstrup-Anderson, Professor and World Food Prize Laureate, and Alice Ruhweza, Africa Regional Director of the World Wildlife Fund (WWF).

Moderated by Margaret Bath, Chair of CIMMYT Board of Trustees, the panelists conveyed Ag4Peace’s aims of building productive, sustainable, and resilient agrifood systems, improving livelihoods for small-scale producers and other value chain actors, and deliver nutritious, affordable diets.

“Hunger is part of the picture of conflict,” explained Burke. “These strapped communities are often competing for resources with each other, within their own boundaries, and sometimes food is a weapon in these places, just as destructive as a bomb or a gun. Without food there is no peace, in the near or the long-term.”

Trade-offs versus win-wins

Pinstrup-Anderson ruminated on the importance of win-wins, which are solutions that work for supporting human health and protecting our natural environment without sacrificing results in one area for results in another. “We do not have to give up improving nutrition just to save the climate or save the earth – we can do both,” he said.

The significance of strong partnerships arose multiple times, such as when Otero explained, “It is not a matter of working just with the agriculture ministers but also with other ministers – foreign affairs, social development, environmental – because agriculture is a sector that crosses across all these institutions.”

Ruhweza explored whether threats to food security, such as COVID-19, conflict, and climate change, can also bring opportunities. “The right action on food systems can also accelerate the delivery of all our goals on climate and nature,” she said. “WWF is looking forward to partnering with this initiative.”

Final remarks from Julie Borlaug, President of the Norman Borlaug Foundation, where the platform will be housed, reiterated a call for more partners to join the coalition. “This is a learning lesson as we go. We will iterate over and over until we get it right, so we need all of you to be involved in that,” said Borlaug. “Join us as we move forward but let us know as we’re going sideways.”

CGIAR scientist honored with award

The winner of the annual Norman Borlaug Award for Field Research and Application award was announced at the Borlaug Dialogue, which this year went to Mahalingam Govindaraj, Senior Scientist for Crop Development at HarvestPlus and at the Alliance of Bioversity International and CIAT, a CGIAR research center.

Govindaraj received the award for his leadership in mainstreaming biofortified crops, particularly high-yielding, high-iron, and high-zinc pearl millet varieties. This work has contributed to improved nutrition for thousands of farmers and their communities in India and Africa, and estimates show that, by 2024, more than 9 million people in India will be consuming iron- and zinc-rich pearl, benefiting from improved nutrition.

Research shows impact of root and crown rot in wheat

Written by Sarah McLaughlin on . Posted in Publications.

Kazakhstan is the ninth largest country in the world and the fourteenth largest producer of wheat; in 2021 alone, the country produced 14.3 million tons (t) of wheat on 12.1 million hectares (ha). Despite this impressive figure, wheat yield in the country falls below average at 1172.5 t/ha compared to 3474.4 t/ha globally.

Research into wheat diseases in Kazakhstan has primarily revolved around airborne fungal foliar diseases, such as stem rust, leaf rust and stripe rust, which can be devastating for farmers and their crops. However, the effects of fungi relating to wheat root and crown root were yet to be examined – these diseases affect yields, stands and grain quality due to infections that cause damping-off, blight, necrosis, and dry rotting.

Using plant samples taken during the 2019 growing season, scientists from the International Maize and Wheat Improvement Center (CIMMYT) conducted a quantitative survey to determine the distribution of this fungi. Using morphological and molecular tools on 1,221 samples from 65 sites across the central, eastern, and southeastern region, scientists found that Bipolaris sorokiniana and Fusarium acuminatum were the most predominant fungal species isolated.

In total, 74 isolates from 16 species were tested, revealing that F. culmorum and F. pseudograminearum, B. sorokinaiana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. orvzae were virulent fungi.

Results show the diverse spectrum of pathogenic fungal species linked to wheat crown and root rot in Kazakhstan and is highly likely to be the first report from the country on the presence of F. seudograminearum, Fusarium sp., C. spicifera, and C. inaequalis.

With this new data, scientists can develop mitigations to prevent crop loss and improve wheat yield across Kazakhstan.

Opening the door to commercial fodder production

Written by Sarah McLaughlin on . Posted in Features.

The paired challenges of population growth and climate change have put smallholder farmers in Zambia in a squeeze. In the Southern Province, the center of agricultural production for the nation, smallholder dairy farmers struggle to increase their production of fodder to commercially viable levels in the face of a long dry season that climate change is intensifying.

Smallholder farmers looking to support their families, enhance the local food supply, and sustain economic growth in their areas are at a distinct disadvantage because agriculture in Zambia is dominated by massive commercial operations with plentiful capital, large tracts of land, and expensive machinery, with most of their output marked for export.

The International Maize and Wheat Improvement Center (CIMMYT) is partnering with the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the University of Hohenheim to identify key barriers and sustainable pathways to smallholder farmer success through a mechanization working group. This work is being carried out through the global initiative One World No Hunger, which launched Green Innovation Centers for the Agriculture and Food Sector (GIC) in 15 member countries in 2014.

“Mechanization is a critical aspect of responding to these problems and the core business of the GIC is to develop knowledge,” said Chimuka Mulowa, a GIC cooperative development advisor based in Choma, Zambia. “Our efforts provide training to smallholder farmers with a focus on adaptive mechanization as a critical ingredient in a holistic approach. Projects in the past have purchased equipment, but we integrate knowledge with existing infrastructure.”

In Zambia, the GIC works with 22 cooperatives to reach 10,000 small-scale farmers with training sessions on fencing land to grow grass, climate smart breeding, irrigation, and more. The GIC has reached their training goal, but implementation of new practices has been more difficult, with only about half the farmers adopting what they have learned so far.

To better understand the challenges smallholder farmers face in Zambia, Mulowa and the GIC partnered with researcher Vuyo Maphango, who was completing his master’s degree in agricultural economics at the University of Hohenheim under the supervision of Lennart Woltering, a senior scientist at CIMMYT. Woltering developed a tool called Scaling Scan which analyzes barriers to growth for successful innovations in the pilot stage and brings focus to key ingredients for expansion.

Mulowa and Maphango used Scaling Scan to assess the progress of the GIC efforts in Zambia. As they expected, for smallholder farmers trying to get into commercial fodder production, financing was a challenge. At $35,000 USD for a machinery like hay balers used once per year, it can take a farmer up to a decade to recoup such an investment. But Scaling Scan also identified surprising challenges, such as a lack of collaboration and uneven dissemination of knowledge and skills.

“There was a lot of progress coming out of the Scaling Scan process,” Maphango said. “Growing the cooperatives of farmers is a critical GIC focus now, and this helps with the finance issues as well. Where farmers can’t afford to buy or develop high-quality seed, they can come together, share which seeds are working best for them, and help each other adopt best practices. Staying close as a cooperative also gives farmers stronger bargaining power with the ability to pool together finances.”

More affordable equipment will also help. Smaller, less expensive choppers and chuff cutters ($1500-2000 USD) are already available for silage production, but there is not a well-established tradition of employing silage production in Zambia, and farmers there have struggled to adopt it. Similar machines are making their way onto the market for fodder production and will require farmers to develop a new set of technical skills.

Mulowa and Maphango are also rethinking approaches to training. As an incentive, non-government organizations (NGOs) often pay participants for their time when they attend training sessions, but government ministries can’t sustain this practice beyond the end of a project due to lack of funding. For a deeper level of skill and knowledge development, GIC wants to help farmers see the benefit of training as providing its own incentive–continuing professional education will pay off, both in terms of better agricultural and business practices, and better financial outcomes. The key to this transition is results. When farmers see their yield improving because of skills and practices they developed in training, they will be hungry for more.

Success, for Zambian smallholders, is a door that is opening slowly but surely. “Early adopters are making progress,” Maphango said. “Some are growing their own grass, others are fencing their land and developing irrigation.” As these practices take root, and farmers share victories with cooperative members; the value of ongoing training becomes clear, and the door may open further for others to walk through.

The two-wheel tractor has been a life changer for Ranganai Muzorori.

At a recent seed and mechanization fair in Zimbabwe, the maize farmer, who purchased the tractor on a lease-to-own basis, said he now enjoys bigger earnings.

Not only has he realized a significant change in his income due to the tractor, he no longer has to struggle to shell maize because he now has access to a machine that strips the corn off the cob.

In a day I can shell about 10 tons, which is helpful for saving precious time, Muzorori said.

Land preparation is also less arduous. “We no longer rely on animal draft power or our own manual labor, but the tractor,” he added.

Due to the versatility of the tractor, which has multiple attachments depending on the task that needs to be done, he has also secured a formal annual contract with Great Zimbabwe Hotel in the southeastern city of Masvingo. He attaches a trailer to the tractor to collect garbage and transport it to the dump, diversifying his income beyond conventional on-farm earnings.

Before the International Maize and Wheat Improvement Center (CIMMYT), in partnership with Zimbabwe’s government extension arm Agritex (Department of Agricultural, Technical and Extension Services), introduced low-cost tractors and small engine-operated farm machinery, such innovations were just a dream for many farmers in Zimbabwe who could not afford to pay $30,000 USD.

“We need to move with the times, the days of relying on either draft power or manual labor should be a thing of the past,” said Caleb Mnkandla, an Agritex supervisor. “With more exposure forums for farmers like this, we can accelerate the adoption of mechanized agriculture even at a smallholder farmer level.”

Improved mechanized tools are also now available to smallholder farmers.

Increased efficiency lightens load

A recent surge of January and tickborne diseases, which affect livestock, added to difficulties faced by many communal farmers due to draft-power shortages during land preparation and planting seasons.

This has translated to reduced yields for many farmers as the timing and efficiency of land preparation and planting has a direct impact on crop yields.

Other farmers in Masvingo are also seeing the transformative capabilities of such mechanization, as reflected in testimonials during the R4 Rural Resilience and ZAMBUKO seed and mechanization fair held in October.

The project – funded by the United States Agency for International Development (USAID), the Swiss Agency for Development and Cooperation (SDC), and the World Food Programme (WFP) – is intended to reduce the arduous manual labor associated with the use of hand operated ploughs and tools.

“Smallholder production systems in Africa have been heavily comprised of intense drudgery which makes farming less attractive for youth and difficult for women,” said Abdul Matin, a lead scientist with CIMMYT.  “The new mechanization technologies we are bringing in are meant to reduce drudgery and cost, and add increased efficiencies to smallholder farmer operations.”

Greater accessibility through financing

In a joint collaboration, Agritex and CIMMYT provide an innovative financial scheme under which service providers pay a commitment fee of $500 USD to access the machinery. They then receive a grace period of four months and pay instalments of $100 USD a month for 20 months. The project covers half of the machinery cost as risk sharing.

So far, there are 34 service providers participating in Masvingo, offering mechanization services to smallholder farming communities for a fee. The project is a scalable pilot for the rest of the country.

The service provider model puts the focus on the asset owners, who not only enjoy the benefits of the mechanization, but also offer services to surrounding farming communities which causes exponential impact, Matin said.

The package of services farmers have been accessing include tillage, transportation, shelling and threshing services.

Tractors can be used for transportation year round, providing steady income for service providers.

The fair provides a platform to demonstrate and showcase the impact of the new technology to farmers, said Pamela Chirwa, project coordinator for CIMMYT’s Global Maize Program in the Southern Africa Regional Office located in Zimbabwe, who coordinated the event.

“We need to continuously expose farmers to other farmers who have moved on to mechanized production,” she said. “Such farmer-to-farmer extension makes it easier for others to adopt technology as they relate to each other better.”

“Adopting improved maize seed varieties alongside two-wheel tractors and other machinery will also improve capacity and potential earnings,” said Christian Thierfelder, a principal scientist with CIMMYT, addressing farmers in Masvingo, emphasizing that for conservation agriculture, mechanized equipment is a labor-saving technology.

New WIRES initiatives to advance women’s careers in science and research

The CGIAR Women in Research and Science (WIRES) employee-led resource group recently had a virtual engagement to discuss the progress and new happenings in the group. The meeting, themed “Connecting and Mentoring, What’s new with WIRES!” was held on October 24.

Giving the opening remarks, The Alliance of Bioversity International and CIAT Knowledge Sharing Specialist Arwen Bailey stated that the group was launched in July 2020 to empower and increase the visibility of women research and science professionals across CGIAR.

Bailey and other co-coordinators, International Maize and Wheat Improvement Center (CIMMYT) Technical Program Manager Aparna Das, IITA HarvestPlus Cassava Breeder Elizabeth Parkes, and International Center for Agricultural Research in the Dry Areas (ICARDA) Communication Consultant Nada Abdelhamid, shared their reasons for volunteering in WIRES. Participants also highlighted their expectations for the meeting.

Explaining the vision and mission of the group, Das stated that WIRES aims to provide tools and knowledge that support professional development. She added that this would create visibility for CGIAR women in science and research so their voices are heard and their contributions recognized. “We are an open community that accommodates both men and women who are willing to support the vision of WIRES,” she said.

Discussing her reason for sponsoring WIRES, CGIAR Executive Managing Director Claudia Sadoff said she admires the efforts and engagement of the team in supporting women despite having other personal life activities. She added that the increase in the percentage of women scientists calls for more effort to train and empower these women. “Thanks for allowing me to be your sponsor,” she said. International Livestock Research Institute (ILRI) Director General Jimmy Smith, also a sponsor, stated that his motivation to join the cause stems from his experience raising daughters.

Highlighting how intending volunteers can support WIRES, Das spoke on mentorship as a promising strategy to advance Gender, Diversity and Inclusion (GDI) in the workplace as it offers access and advocacy for women. Explaining the criteria for engagement, she stated that a mentor must be passionate about advancing GDI, while the mentee must be a middle to senior-level career woman researcher/scientist with an appetite to learn. “Registration for the program will begin in November, and the program will kick off in December. Interested mentors and mentees who meet the criteria can register and be trained,” she said.

Other new WIRES initiatives coming up before the end of 2022 include “Random coffee,” where members can schedule to meet physically or virtually to build a vibrant relationship and network, and “Focus groups” for discussions that will ensure continuous improvement for WIRES.

Closing out the meeting, CGIAR Global Director of People and Culture, Fiona Bourdin-Farrell, summarized ways volunteers can help to advance women in science and research in CGIAR. She mentioned that it starts with joining the WIRES team, being a part of the mentoring program, engaging in the random coffee pilot, and joining focus groups. “You can contribute to the information in the newsletter. You can also register as both mentor and mentee as long as you meet the criteria,” she concluded.

The democratization of innovation

Written by Sarah McLaughlin on . Posted in Features.

When the Norwegian Red Cross hired Kristian Wengen and his consulting firm Tinkr to launch a “Scaling for Success” initiative, he found himself at a crossroads. From international aid projects aiming to address the UN Sustainable Development Goals (SDGs) to private companies seeking to expand their market, everyone was talking about the challenges of scaling up – expanding and sustaining successful programs to reach a greater number of people – but there were few clear paths to solutions.

The Scaling Scan has solutions to offer

But when Wengen came across a project using a tool called the Scaling Scan that identifies and analyzes 10 critical elements for assessing the scalability of any pilot project, he knew he had found a way forward. He was excited, but also worried because the project using the Scaling Scan had concluded.

Concerned he would lose access to the best tool he had found by far, Wengen connected with Lennart Woltering, who created the Scaling Scan for the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with a Dutch-supported project on private-public partnerships called the PPPLab. Woltering and Wengen began a dialogue regarding repurposing the Scaling Scan for Wengen’s context.

“What I like about the Scaling Scan is that it works on a very detailed level to produce systemic results,” said Wengen. “It brings a simple approach to the complex problems of scalability, which allow organizations to achieve efficient solutions, regardless of their geographic or demographic context.”

The Scaling Scan focuses attention on discrete components – from finance and business cases to technology and skills – which are necessary to successfully scale an innovation. But it also spurs insight into how each of these necessary ingredients complement each other as a project prepares to successfully transition, reproduce, and expand.

Wengen believes the most effective work of the Scaling Scan happens in team conversations, and it helps deliver clear feedback that can form the basis of discussions that go straight to the heart of the matter. While the challenges of scaling an innovation are complex, the Scaling Scan cuts through the noise and focuses attention on solving the most important problems, whether related to leadership, collaboration, or public sector governance.

Scaling the Scaling Scan

In their conversations, Wengen and Woltering identified opportunities for improving the Scaling Scan. For example, Wengen is building a digitized, web-based version that, like the original Scaling Scan, will be freely available. He calls it a scorecard, a smaller version which capitalizes on the ability of the Scan to promote productive dialogue that moves a project forward. “I am thrilled to help broaden the reach of the Scaling Scan, as making it available for a much wider audience will democratize innovation,” Wengen said.

“Kristian’s adaptations are exactly how I designed the Scaling Scan to work,” said Woltering. “I wanted it to be straightforward enough to be useful across a broad range of business and development applications and flexible enough to be tailored to the specific needs of a particular region, culture, or marketplace.” Seeing how Wengen has utilized the Scaling Scan across a variety of markets has spurred Wennart to develop the Scaling Scan website, where other interested practitioners can download the tool and share their own innovations. “The Scaling Scan truly has utility across the broadest geographies and socioeconomic ranges,” said Wennart.

Wengen is hoping his scaling scorecard will help drive success in a new collaboration he is undertaking with Innovation Norway, a state-owned organization that helps Norwegian businesses grow and export promising products and services. Wengen believes his scorecard will add immense value to a diverse set of projects ranging from business management software helping bakeries reduce waste and increase profits to zero-carbon ocean-going ships and virtual medical training systems.

This kind of transfer and growth shows that even the Scaling Scan itself can be scaled up from the tropics to the Arctic Circle, and Woltering can’t wait to see where the next successful adaptation will spring up.
