Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

Breaking Ground: Tek Sapkota finds ways to reduce emissions from agriculture without compromising food security

Written by Rodrigo Ordóñez on December 13, 2018. Posted in Features.

As the world population increases, so does the need for food. “We need to produce more to feed increasing populations and meet dietary demands,” says Tek Sapkota, agricultural systems and climate change scientist at the International Maize and Wheat Improvement Center (CIMMYT). In the case of agriculture, the area of land under cultivation is limited, so increased food production has to come through intensification, Sapkota explains. “Intensification means that you may be emitting more greenhouse gases if you’re applying more inputs, so we need to find a way to sustainable intensification: increase the resilience of production systems, but at the same time decrease greenhouse gas emissions, at least emission intensity.”

Sapkota is involved in a number of global climate change science and policy forums. He represents CIMMYT in India’s GHG platform, a multi-institution platform that regularly prepares greenhouse gas emission estimates at the national and state levels and undertakes relevant policy analyses. Nominated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and his country, Nepal, he is one of the lead authors of the “special report on climate change and land” of the Intergovernmental Panel on Climate Change (IPCC).

He coordinates climate change mitigation work at CIMMYT. “I am mainly involved in quantification of greenhouse gas emissions and the environmental footprint from agricultural production systems, exploring mitigation options and quantifying their potential at different scales in different regions,” Sapkota says. In addition, he explores low-carbon development activities and the synergies between food production, adaptation and mitigation work within the different components of CIMMYT’s projects.

Agriculture is both a victim of as well as a contributor to climate change, Sapkota explains. “Climate change affects all aspects of food production, because of changes in temperature, changes in water availability, CO₂ concentrations, etc.,” he says. “The other side of the coin is that agriculture in general is responsible for about 25 to 32 percent of total greenhouse gas emissions.”

Measuring emissions and examining mitigation options

A big part of Sapkota’s work is to find ways to mitigate the effects of climate change and the emissions from the agricultural sector. There are three types of mitigation measures, he explains. First, on the supply side, agriculture can “increase efficiency of the inputs used in any production practice.” Second, there’s mitigation from the demand side, “by changing the diet, eating less meat, for example.” Third, by reducing food loss and waste: “About 20 percent of the total food produced for human consumption is being lost, either before harvest or during harvest, transport, processing or during consumption.”

Sapkota and his team analyze different mitigation options, their potential and their associated costs. To that purpose, they have developed methodologies to quantify and estimate greenhouse gas emissions from agricultural products and systems, using field measurement techniques, models and extrapolation.

“You can quantify the emission savings a country can have by following a particular practice” and “help countries to identify the mitigation practices in agriculture that can contribute to their commitments under the Paris climate agreement.”

Their analysis looks at the biophysical mitigation potential of different practices, their national-level mitigation potential, their economic feasibility and scalability, and the country’s governance index and readiness for finance — while considering national food security, economic development and environmental sustainability goals.

Recently, Sapkota and his colleagues completed a study quantifying emissions from the agricultural sector in India and identifying the best mitigation options.

This type of research has a global impact. Since agriculture is a contributor to climate change “better management of agricultural systems can contribute to reducing climate change in the future,” Sapkota says. Being an important sector of the economy, “agriculture should contribute its share.”

Impact on farmers

Sapkota’s research is also helping farmers today. Inefficient use of products and inputs is not only responsible for higher greenhouse gas emissions, but it also costs farmers more. “For example, if farmers in the Indo-Gangetic Plain of India are applying 250 to 300 kg of nitrogen per hectare to produce wheat or rice, by following precision nutrient management technologies they can get similar yield by applying less nitrogen, let’s say 150 kg.” As farmers cut production costs without compromising yield, “their net revenue from their products will be increased.”

Farmers may also get immediate benefits from government policies based on the best mitigation options. “Governments can bring appropriate policy to incentivize farmers who are following those kinds of low-emission technologies, for example.”

Farmers could also get rewarded through payments for ecosystem services or for their contribution to carbon credits.

Sapkota is happy that his work is beneficial to farmers. He was born in a small village in the district of Kaski, in the mid-hills of Nepal, and agriculture was his family’s main livelihood. “I really enjoy working with farmers,” he says. “The most fascinating part of my work is going to the field: talking to farmers, listening to them, learning what kind of farming solutions they’re looking for, and so on. This helps refine our research questions to make them more strategic, because the way farmers look at a problem is sometimes entirely different from the way we look at it.”

When he was in Himalaya Secondary School, he studied agriculture as a vocational subject. “I was interested because we were doing farming at home.” This vocation got cemented in university, in the 1990s. When he heard about the agricultural industry and the future opportunities, he decided to pursue a career in science and focus on agriculture. He got his bachelor’s and master’s degree of science in agriculture from the Institute of Agriculture and Animal Science (IAAS), Tribhuvan University, in Nepal.

*Tek Sapkota (second from left) and other scientists participate in a small group session during a meeting of lead authors of the Intergovernmental Panel on Climate Change (IPCC).*

A global path

He first heard about CIMMYT when he was doing his master’s. “CIMMYT was doing research in maize- and wheat-based plots and systems in Nepal. A few of my friends were also doing their master theses with the financial support of CIMMYT.” After his master’s, he joined an organization called Local Initiatives for Biodiversity, Research and Development (LI-BIRD) which was collaborating with CIMMYT on a maize research program.

Sapkota got a PhD in Agriculture, Environment and Landscapes from the Sant’Anna School of Advanced Studies in Italy, including research in Aarhus University, Denmark.

After defending his thesis, in 2012, he was working on greenhouse gas measurement in the University of Manitoba, Canada, when he saw an opening at CIMMYT. He joined the organization as a post-doctoral fellow and has been a scientist since 2017. Sapkota considers himself a team player and enjoys working with people from different cultures.

His global experience has enriched his personal perspective and his research work. Through time, he has been able to see the evolution of agriculture and the “dramatic changes” in the way agriculture is practiced in least developed countries like Nepal. “When I was a kid agriculture was more manual … but now, a lot of technologies have been developed and farmers can use them to increase the efficiency of farming”.

Screening cycle for deadly MLN virus set to begin in Kenya during 2019

Written by on December 11, 2018. Posted in News.

*CIMMYT partners visit the Maize Lethal Necrosis screening facility in Kenya. (Photo: Joshua Masinde/CIMMYT)*

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya, will begin its phenotyping (screening/ indexing) cycle of 2019 at the beginning of January 2019 and in other four intervals throughout the year. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.

In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.

MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields.

CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm (for hybrid, inbred and open pollinated varieties) against MLN in a quarantined environment.

This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 180,000 accessions (more than 270,000 rows of maize) from more than 15 multinational and national seed companies and national research programs.

Partners can now plan for annual MLN Phenotyping (Screening / Indexing) during 2019 with the schedule below. The improved and streamlined approach for MLN phenotyping should enable our partners to accelerate breeding programs to improve resistance for Maize MLN for sub-Saharan Africa.

2019 annual phenotyping (indexing / screening) schedule:

When the seeds are available	Planting Period – Planned	MLN Screening / Indexing
December	Second Week of January	MLN Indexing
March	Second week of April	MLN Screening
June	Second Week of July	MLN Indexing
August	Second Week of September	MLN Screening
October	Second week of November	MLN Indexing

More information about the disease and resources for farmers can be found on CIMMYT’s MLN portal.

Please note that it can take up to six weeks to process imports and clear shipments.

New publications: Climate change impact and adaptation for wheat protein

Written by Courtney Brantley on December 11, 2018. Posted in Publications.

Globally, wheat provides around 20 percent of the calories and protein in human diets. By mid-century, crop production must increase by 60 percent to meet global food demand and help reduce hunger, a challenge made even harder by climate change. “Climate Change Impact and Adaptation for Wheat Protein,” a study published in Global Change Biology in September 2018, examines why wheat grain protein concentration — a determinant of grain quality — is often overlooked in relation to improving global crop production in the face of climate change challenges.

“The impact of climate change on crops typically focuses on productivity; however, there are nutritional implications too,” says key contributor to the study Matthew Reynolds, wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT). “Since wheat also provides a significant proportion of protein in the diets of millions of resource-poor people, the negative impact of increased atmospheric CO2 on protein concentration in the grain is a disturbing fact,” stated Reynolds. “If not addressed, it could have a devastating impact on the health and livelihoods especially of marginalized people who cannot easily afford diverse sources of protein in their diet.”

Multi-location field trials, in addition to model testing, were used to systematically analyze the effects of increasing temperature, heat shocks, elevated atmospheric CO2 concentration, nitrogen, water deficiency and the combination of these factors on yield and wheat grain protein in the world’s main wheat producing regions. This study marked the first time that heat shock and high temperature interaction with elevated CO2 concentration was tested through an impact model. As noted in the study, “This is the most comprehensive study ever done of the effect of climate change on yield and the nutritional quality of one of the three major sources of human food security and nutrition.”

Farmers cite climate change as biggest challenge, says World Farmers Organization at COP24 talks

KATOWICE, Poland (CIMMYT) — Controversies over fossil fuels, indigenous rights and the intricacies of the 2015 Paris Agreement, which was designed to keep global temperatures from rising no more than 1.5 degrees Celsius above pre-industrial levels, are just some of the key topics in focus at U.N. COP24 climate talks.

A vital thread in the climate change narrative, much debated in the corridors of the conference center in Katowice, Poland, is agriculture — a fragile yet vital sector of the global economy which produces about a third of global greenhouse gas emissions.

The member-driven World Farmers Organization (WFO), a group of 1.5 billion farmers from 54 countries, represents the farm community at the United Nations on climate change and other topics, including the Sustainable Development Goals 2030 Agenda.

A new “Climakers” initiative, launched on the sidelines of the COP24 talks, will help address the biggest threat farmers say they fear, according to Luisa Volpe, head of policy development at WFO in an interview. Volpe, who has been with WFO since 2014, formerly worked on farmers programs with the International Fund for Agriculture and Development (IFAD).

“I decided I wanted to move to the other side of the coin and work directly with those who are the targets of big multilateral governmental organizations and government policies,” Volpe said, adding that farmers, tasked with producing more with less for a growing population, are also among those most affected by climate change.

Q: What is the biggest challenge farmers face?

A: The view of the farmers that I represent is that climate is the most important challenge because climate may have an impact on the harvest, on the seeds, on the area where they want to harvest, whether they should move, migration of young farmers to the city, on the kind of products they can produce. Climate change also has an impact on market prices. Of course there are others — they include access to infrastructure, access to financing, having proper insurance and availability and access to financing mechanisms. Farmers say that among this range of issues they may face, climate is probably the most intense because it’s probably the one that they cannot control. They’re just influenced by it and there is little that they can do. Foreseeing weather patterns is very limited — with technology they’re able to predict weather patterns one week before, but not longer. It’s really challenging for them.

Q: How are farmers managing the challenge of climate change?

A: This is something that represents the common ground for all the farmers of the world despite differences in terms of geographical area, in terms of type of business that they manage. Last May in Moscow, during the WFO general assembly, WFO got a unanimous mandate from all of our constituency — made up of national farmers organizations from all over the world — to initiate, establish and propose a new agenda for climate, driven by the farmers themselves. Basically, our members realized that the impact of climate change on farming is something that’s common to all farmers around the world. Their proposal is to first create a broad alliance with the farmers organizations worldwide who may have either a regional voice or a global voice in order to represent all the areas of the world and work together — to join their hands in a new initiative on climate change.

Q: How will the initiative take shape?

A: The outcome of the initiative will be an overarching document with which we as a farmers organization can advocate at the international level and our members can advocate at the national level. What we’re planning to do is to organize a series of regional workshops to meet the farmers themselves and collect case studies and best practices of what farmers are already doing to mitigate and adapt to climate change. Farmers, as all other sectors of the world, are contributing to the causes of climate change. This agenda would not work if we don’t add other actors to the alliance. It’s farmers first, but then a close dialogue with CGIAR.

We’ve started with CCAFS, the CGIAR Research Program on Climate Change, Agriculture and Food Security. We want to work closely with them to make sure that the practices we propose to governments as examples to follow and to scale up when they propose their Nationally Determined Contributions (NDCs) — country level contributions to reducing emissions as part of the Paris Agreement — are effective and science based. Here, we propose to close the gap with science and improve cooperation between farmers and science, so that science really responds to the questions farmers pose — to which they align their practices. In this sense, the scientific research can be more aligned to what farmers actually need, while the farmers may improve their own practices by also responding to the needs of the research.

To really tackle climate change challenges, we need innovation and technologies that are science-based and sustainable, because the main principle of all these agendas is sustainability. What we propose is that farmers contribute by improving their access to innovation research and technology to make their production more sustainable.

Q: Could you explain how you intend to take this practice to a global scale?

A: The other actors we plan to involve are those belonging to the food value chain, because we think that farmers alone cannot be the only solution. That’s why we’re establishing a partnership, for example, with the International Fertilizer Association as well as the International Seeds Federation. We’re in a partnership with Crop Life because they represent a huge element in the food chain. It has to be a global movement if you really want to achieve something that’s effective and efficient. We’ll expand also to other actors in the food chain. We’re also negotiating with multilateral governmental organizations because we need their support for advocacy work we want to do. Governments will become the targets instead of being those who will just propose and impose policies to the farmers. In our view, farmers have the solution in their hands already. What we have to do is to put them in a condition to really influence and feed the political documents that governments will adopt and that will become national policies.

Q: What is Climakers and the farmer-driven climate change agenda you launched at COP24?

A: Climakers are those who become part of the global alliance for this new initiative. The alliance is global, the agenda is farmers-driven. Farmers expressing their needs and their challenges and their best practices — together with science and the multilaterals and the private sector is that of supporting the agenda, supporting the farmers and take it to the governments. Climakers is the name we have chosen for those who are on the farmer side because we think that farmers may make the climate.

Q: In terms of the COP24 negotiations, are you getting any sense of what could be happening that could benefit farmers or are more demands being put on farmers?

A: I see it [as] a very slow process. We were very happy when we saw the concept of food security and food production in the Paris Agreement because although there is no mention of agriculture, at least they mentioned food production. It means that probably some little political will to address the farming sector is there. There is a will to implement the Paris Agreement in the agricultural sector. The negotiation is very slow between north and south regarding the mitigation and adaptation issue, and also the fact that financing for climate change is there, but probably the way it is managed is not really supporting the communities because the channels are too complicated and too long… There are probably some seeds up there, but it’s still a long way. That’s why farmers want to propose an icebreaking agenda.

Q: Are there any other key points you would like to make in the context of climate change?

A: One element that is a little bit controversial for me is critical in the development of agriculture and also in tackling climate change, which is innovation — innovation in terms of practices, in terms of technology, in terms of research, but also in terms of creating financing for farmers and to support rural areas. These have to come from the government side, from the value chain actors, from the farmers themselves and also from the science, from the research centers.

If we close the gap between the farmers and the science, it’s probably the way out for boosting development for the rural areas. We don’t have to be scared of being innovative. Innovation doesn’t mean GMOs. Innovation may also mean an innovative way to treat soils. It may be a new way to access markets, create access to finance for farmers, but also an innovative way to interact between governments and the farmers themselves. To me, innovation is the way out really, that can give a boost to this process.

Breeders find strength in diversity at EiB contributor meeting

Written by Sam Storr on December 10, 2018. Posted in Features.

Around 115 members of the CGIAR breeding community, plus others representing national programs, universities, funders and the private sector, met for a three-day discussion of how to co-develop the next generation of advanced breeding programs that will improve the rate at which resource-poor farmers are able to adopt improved varieties that meet their needs.

The annual Excellence in Breeding Platform (EiB) Contributor’s meeting, held this year in Amsterdam from 13-15 November, caps a year of engagement with CGIAR Centers and national agricultural research system (NARS) partners around the world.

*Paul Kimani, from the University of Nairobi, speaks during the meeting. (Photo: Sam Storr/CIMMYT)*

“Although breeding is one of the oldest functions in CGIAR, we have never had a meeting like this with scientists from all the centers,” said Michael Baum, director of Biodiversity and Crop Improvement at the International Center for Agricultural Research in the Dry Areas, (ICARDA). “Within CGIAR, plant breeding started as a science, but now we are looking at how to implement it not as a science but as an operation, as it is done in the private sector, so there are many new concepts.”

Key items on the agenda for November were new tools to develop product profiles and create improvement plans that will define the modernization agenda in each center and across the Platform itself, based in part on the Breeding Program Assessment Tool (BPAT) that most Centers completed in 2018.

The conversation was enriched by Paul Kimani (University of Nairobi) presenting on the Demand-led Variety Design project, which produced the book, “The Business of Plant Breeding.”

Ranjitha Puskur, gender research coordinator at the International Rice Research Institute (IRRI), started an animated discussion on how to incorporate gender into product design by thinking about customer segments.

Tim Byrne from AbacusBio introduced methods for identifying farmer preferences to be targeted by breeding programs.

In breakout sessions, contributors were able to have detailed discussions according to their various specializations: phenotyping, genotyping and bioinformatics/data management. The direct feedback from contributors will be incorporated into EiB workplans for training and tool development for the coming year.

A key outcome of the meeting was an agreement to finalize the product profile tool, to be made available to EiB members in early December 2018. The tool helps breeders to work with other specialisms, such as markets, socioeconomics and gender, to define the key traits needed in new products for farmers. This helps to focus breeding activities towards areas of greatest impact, supports NARS to play a greater role, and creates accountability and transparency for donors, in part by defining the geographic areas being targeted by programs.

“Breeding trees is different to the annual crops,” said Alice Muchugi, genebank manager at the World Agroforestry Centre (ICRAF), “but we are seeing what we can borrow from our colleagues. By uploading what we are doing in maps, for example, donors are able to perceive the specific challenges we are undertaking.”

“I think we have realized there are lot of challenges in common, and the Platform is helping us all work on those,” said Filippo Bassi, durum wheat breeder at ICARDA. “I like to see all the people around the room, if you look at the average age there is a big shift; the number of countries present also tells you a lot.”

Tabare Abadie, R&D external academic outreach lead at Corteva Agriscience, also saw the meeting as a good opportunity to meet a broader group of people. “One of the take homes I hear is [that] there are a lot of challenges, but also a lot of communication and understanding. For me as a contributor it’s an incentive to keep supporting EiB, because we have gone through those changes before [at Corteva], and we can provide some know-how and experience of what happens,” Abadie explained.

“There are still a lot of gaps to fill, but this is a good start,” said Thanda Dhliwayo, maize breeder at the International Maize and Wheat Improvement Center (CIMMYT). “We need to get everyone involved, from leadership down to the guys working in the field.”

International coalition keeps devastating maize disease at bay, but risks still linger

Written by Jérôme Bossuet on December 10, 2018. Posted in Features.

NAIROBI, Kenya (CIMMYT) — When maize lethal necrosis (MLN) was first reported in Bomet County, Kenya, in September 2011 and spread rapidly to several countries in eastern Africa, agricultural experts feared this emerging maize disease would severely impact regional food security. However, a strong partnership across eight countries between maize research, plant health organizations and the private seed sector has, so far, managed to contain this devastating viral disease, which can wipe out entire maize fields. As another emerging pest, the fall armyworm, is making headlines in Africa, African countries could learn a lot from the initiatives to combat MLN on how to rapidly respond to emerging crop pests and diseases.

On November 19-20, 2018, the International Maize and Wheat Improvement Center (CIMMYT), national research and plant protection agencies and seed companies met in Nairobi to review the third year’s progress of the MLN Diagnostics and Management Project, supported by USAID. All participants agreed that preventing any spread of the disease into southern Africa was a great success.

“The fact that we all responded rapidly and productively to this crisis serves as a testament of the success of our collective efforts,” said CIMMYT’s Global Maize Program Director, B.M. Prasanna, while addressing delegates from Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe. “That no new country has reported the MLN outbreak since Ethiopia last reported it in the 2014-2015 period, and that we have managed to keep it at bay from southern Africa and west Africa is no mean feat. It would have been a major food security disaster if the disease had spread throughout sub-Saharan Africa.”

However, the MLN Community of Practice warned that risks of severe outbreaks remain, with new cases of MLN reported during the MLN 2018 survey in several parts of Uganda.

Rapid response to a food security threat

MLN is caused by the combination of the maize chlorotic mottle virus (MCMV) and other common cereal viruses mostly from the potyviridae family — a set of viruses that encompasses over 30 percent of known plant viruses — like the sugarcane mosaic virus (SCMV). This viral disease can result in up to 100 percent yield loss and has devastated the incomes and food security situation of many smallholder farmers in the region.

CIMMYT, in collaboration with national agricultural research institutions, national plant protection agencies and seed sector partners, developed a multi-layered response system including real-time intensive surveillance, screening, and fast-tracking of the MLN resistance breeding program. Thanks to the MLN Screening Facility in Naivasha, Kenya, maize breeders rapidly discovered that most popular maize varieties were susceptible, which could expose poor farmers to the risk of losing their entire maize crops.

Using its global collection of maize lines and numerous crop improvement innovations, CIMMYT was able to develop and release at least 15 MLN-resistant maize varieties in just 2 to 3 years.

One important step was to understand how the disease spread. Epidemiologists quickly pointed out the necessity to work with the seed companies and farmers, as the virus could be transmitted through seeds. The project helped put in place the protocols for seed firms to adhere to for their products to be MLN-free. Affordable and simple seed treatment procedures yielded promising results. The project also created awareness on better farming methods for effective disease control.

National Plant Protection Organizations were mobilized to create intensive awareness. They were also equipped and trained on low-cost innovative field diagnostic tools like MLN immunostrips and the deployment of GPS-based mobile surveillance and reporting systems.

“For the first time, Rwanda was able to conduct a comprehensive survey on MLN in farmers’ fields, commercial seed fields and at agro-dealers. We are glad that through MLN management and awareness programs within the project, MLN incidences have declined,” said Fidele Nizeyimana, maize breeder and pathologist at the Rwanda Agricultural Board (RAB) and the MLN Surveillance team lead in Rwanda.

“Equally important is that the commercial seed sector took the responsibility of testing their seed production fields, made sure that seed exchange is done in a responsible manner and implemented voluntary monitoring and surveillance within their fields,” remarked Francis Mwatuni, MLN project manager at CIMMYT.

“I am happy that Malawi has maintained its MLN-free status as per the intensive MLN surveillance activities we conducted in the country over the last three years,” noted Johnny Masangwa, senior research officer and MLN Surveillance team lead in Malawi. “We are now able to monitor both seed and grain movement through our borders for MLN traces, courtesy of the lab equipment, reagents and training on laboratory analysis we received through the project”.

B.M. Prasanna, director of the CGIAR Research Program on Maize (MAIZE), discusses what the CGIAR offers in rapid response preparedness to newly emerging pests, diseases and crises.

The maize sector should remain vigilant

Daniel Bomet, maize breeder at Uganda’s National Agricultural Research Organization (NARO), warned that with new infections reported in the northern parts of his country, the maize sector needs to remain alert to the threat of MLN. “We need to step up MLN awareness and management programs, and require seed companies to follow the right procedures to produce MLN-free seeds to arrest this trend,” he said.

Tanzania Seed Association Executive Director, Bob Shuma, also warned that MLN could be spreading to the southern highlands of the country as the virus was detected in some seed shipments from three seed companies operating in that region. A comprehensive MLN survey in Tanzania will hopefully soon give an idea of the countrywide status of the disease in the country.

Conference speakers and participants noted that inefficient regulatory processes in maize seed variety release and deployment still stand in the way of rapid release of MLN resistant varieties to farmers across the region.

“How quickly we scale up and deploy the elite MLN-resistant and stress-tolerant varieties to the farmer is the next most important phase of the project,” Prasanna said.

The Kenya Plant Health Inspectorate Service (KEPHIS) General Manager, Phytosanitary Services, Isaac Macharia, said that with the support of the USAID Feed the Future program, the government agency has set up a team dedicated to assisting seed companies doing seed multiplication to fast-track the release of the MLN-resistant varieties to the market. Some Kenyan seed companies announced they will market MLN-resistant varieties for the next cropping season in March 2019.

As the project enters its last year, the MLN Community of Practice looks to ensure the fully functional pest surveillance and management system it has put in place is sustainable beyond the project’s life.

Extension materials on best agronomic practices endorsed by government of Nepal

*Agricultural extension materials on best management practices for rice (left) and cauliflower, developed by CIMMYT as part of the NSAF project.*

KATHMANDU, Nepal (CIMMYT) — Maintenance and enhancement of soil fertility are vital for food security and environmental sustainability. However, a baseline survey conducted through the Nepal Seed and Fertilizer (NSAF) project shows that 95 percent of farmers have poor agronomic literacy. Most of them have little or no knowledge of proper seed and soil management practices, and do not apply fertilizer appropriately. Many farmers are also unaware of micronutrients and their specific role in crop production, so they spray micronutrient solutions as advised by agrovets. While quality seed and mineral fertilizer use are necessary to improve crop yields, use alone is not sufficient to maximize efficiency — how to use these tools is equally, if not more, important.

All these challenges indicate a need to educate farmers and help them adopt good agronomic practices that will maximize crop production and productivity.

As part of the NSAF project, the International Maize and Wheat Improvement Center (CIMMYT) has developed locally appropriate agricultural extension materials to disseminate best management practices for maize, wheat and other crops. The government of Nepal has endorsed the project’s best management practices for rice, maize, wheat, tomato, cauliflower and onion.

These extension materials have information on integrated soil fertility management: a set of agricultural practices that integrates improved seed, mineral fertilizer use and soil organic matter management, all adapted to local conditions to improve agricultural productivity. They also serve to share information on the 4 Rs of fertilizer management stewardship: right source, right rate, right time and right placement.

CIMMYT and NSAF project partners are delivering these innovative extension materials to agrovets, cooperatives, extension agencies, development organizations and other intermediaries. They then use them to provide training to farmers in their working areas.

Training packages include pictorial aids, games, informative handouts, group activities, field guides, demonstrations, field visits and other physical learning tools. All the materials have been developed following an “active learning” framework. Training topics include the principles of integrated soil fertility management, soil pH and liming, crop-specific fertilizer application rates, planting methods, fertilizer splitting, methods of fertilizer placement, seed and fertilizer quality, handling considerations and postharvest practices.

“Training of extension workers and farmers on agricultural and plant nutrient related topics leads to an improvement in agronomic practices by farmers. Farmers that are trained and educated in best agronomic practices tend to realize high yields,” said Ramananda Gupta, Agronomist and Extension Specialist at the International Fertilizer Development Center (IFDC). CIMMYT is partnering with IFDC to implement the activities of the NSAF project related to fertilizer, including agricultural extension programs, policy support and market development.

All training materials have been field-tested with farmers, agro-dealers, government extension specialists and cooperatives. The training content has been reviewed by the Nepal Agricultural Research Center and Department of Agriculture. “The content of the best management practice materials are essential knowledge and skills farmers need to sustainably intensify production. Adoption of best management practices will significantly contribute in developing the rice sector as well as other related crops,” commented Ram Baran Yadaw, Rice Coordinator at the National Rice Research Program.

The NSAF project team is piloting the dissemination of improved technologies, skills and extension materials to farmers through local governments and private companies, using different tools and methods. The extension materials on best management practices will be publicly available, so improved seed and soil fertility technologies can be more accessible to farmers.

CIMMYT is also partnering with Viamo to adapt all the materials into an SMS and Interactive Voice Response (IVR) system to further scale up the program in the country, potentially reaching 12 million mobile phone subscribers.

The Nepal Seed and Fertilizer (NSAF) project promotes the use of improved seeds and integrated soil fertility management technologies along with effective and efficient extension programs across 21 “Zone of Influence” districts and in five earthquake-affected districts. The project is funded by the United States Agency for International Development (USAID), as part of the Feed the Future initiative. The project is led by International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Nepal’s Ministry of Agricultural Development and partners including the International Fertilizer Development Center (IFDC) and the Center for Environment and Agricultural Research, Extension and Development (CEAPRED).

A wheat self-sufficiency roadmap for Ethiopia’s future

Written by Jérôme Bossuet on December 5, 2018. Posted in Features.

The Ethiopian government announced recently that the country should become wheat self-sufficient over the next four years. Why is boosting domestic wheat production important for this country in the Horn of Africa, and could wheat self-sufficiency be attained in the next four years? The Ethiopian Institute for Agricultural Research (EIAR), with the support of International Maize and Wheat Improvement Center (CIMMYT), gathered agriculture and food experts from the government, research and private sectors on November 23, 2018, to draw the first outlines of this new Ethiopian wheat initiative.

The low-tech domestic wheat farming and price support issue

Despite a record harvest of 4.6 million metric tons in 2017, Ethiopia imported 1.5 million tons of wheat the same year, costing US$600 million. Population growth, continuous economic growth and urbanization over the last decade has led to a rapid change in Ethiopian diets, and the wheat sector cannot keep up with the growing demand for pasta, dabo, ambasha and other Ethiopian breads.

The majority of Ethiopia’s 4.2 million wheat farmers cultivate this cereal on an average of 1.2-hectare holdings, with three quarters produced in Arsi, Bale and Shewa regions. Most prepare the land and sow with draft animal power equipment and few inputs, dependent on erratic rainfall without complementary irrigation. Yields have doubled over the last 15 years and reached 2.7 tons per hectare according to the latest agricultural statistics, but are still far from the yield potential.

According to data from the International Food Policy Research Institute (IFPRI), wheat is preferred by wealthier, urban families, who consume 33 percent more wheat than rural households. Ethiopia needs to rethink its wheat price support system, which does not incentivize farmers and benefits mostly the wealthier, urban consumers. Wheat price support subsidies could, for instance, target bakeries located in poor neighborhoods.

Where to start to boost wheat productivity?

Ethiopia, especially in the highlands, has an optimum environment to grow wheat. But to make significant gains, the wheat sector needs to identify what limiting factors to address first. The Wheat initiative, led by Ethiopia’s Agricultural Transformation Agency (ATA), has targeted 2,000 progressive farmers across 41 woredas (districts) between 2013 and 2018, to promote the use of improved and recommended inputs and better cropping techniques within their communities. A recent IFPRI impact study showed a 14 percent yield increase, almost enough to substitute wheat imports if scaled up across the country. It is, however, far from the doubling of yields expected initially. The study shows that innovations like row planting were not widely adopted because of the additional labor required.

Hans Braun, WHEAT CGIAR research program and CIMMYT’s Global Wheat Program director, believes Ethiopian farmers can achieve self-sufficiency if they have the right seeds, the right agronomy and the right policy support.

One priority is to increase support for wheat improvement research to make wheat farmers more resilient to new diseases and climate shocks. Drought and heat tolerance, rust resistance and high yields even in low-fertility soils are some of the factors sought by wheat farmers.

International collaboration in durum wheat breeding is urgently needed as the area under durum wheat is declining in Ethiopia due to climate change, diseases and farmers switching to more productive and resilient bread wheat varieties. Braun advises that Ethiopia set up a shuttle breeding program with CIMMYT in Mexico, as Kenya did for bread wheat, to develop high-yielding and stress-resistant varieties. Such a shuttle breeding program between Ethiopia and Mexico would quickly benefit Ethiopian durum wheat farmers, aiming at raising their yields similar to those of Mexican farmers in the state of Sonora, who harvest more than 7 tons per hectare under irrigation. This would require a policy reform to facilitate the exchange of durum germplasm between Ethiopia and Mexico, as it is not possible at the moment.

Ethiopia also needs to be equipped to respond quickly to emerging pests and diseases. Five years ago, a new stem rust (TKTTF, also called Digalu race) damaged more than 20,000 hectares of wheat in Arsi and Bale, as Digalu — the popular variety used by local farmers — was sensitive to this new strain. The MARPLE portable rust testing lab, a fast and cost-effective rust surveillance system, is now helping Ethiopian plant health authorities quickly identify new rust strains and take preventive actions to stop new outbreaks.

Invest in soil health, mechanization and gender

In addition to better access to improved seeds and recommended inputs, better agronomic practices are needed. Scaling the use of irrigation would certainly increase wheat yields, but experts warn not to dismiss adequate agronomic research — knowing the optimal water needs of the crop for each agroecological zone — and the underlying drainage system. Otherwise, farmers are at risk of losing their soils forever due to an accumulation of salt.

‘’2.5 billion tons of topsoil are lost forever every year due to erosion. A long-term plan to address soil erosion and low soil fertility should be a priority,” highlights Marco Quinones, adviser at ATA. For instance, large-scale lime application can solve the important issue of acid soils, where wheat does not perform well. But it requires several years before the soil can be reclaimed and visible yield effects can be seen.

Mechanization could also boost Ethiopian wheat production and provide youth with new job opportunities. Recent research showed smallholder farmers can benefit from six promising two-wheel tractor (2WT) technologies. Identifying the right business models and setting up adapted training programs and financial support will help the establishment of viable machinery service providers across the country.

Better gender equity will also contribute significantly to Ethiopia becoming self-sufficient in wheat production. Women farmers, especially female-headed households, do not have the same access to trainings, credit, inputs or opportunities to experiment with new techniques or seed varieties because of gender norms. Gender transformative methodologies, like community conversations, can help identify collective ways to address such inequalities, which cost over one percent of GDP every year.

‘’With one third better seeds, one third good agronomy and one third good policies, Ethiopia will be able to be wheat self-sufficient,” concluded Braun. A National Wheat Taskforce led by EIAR will start implementing a roadmap in the coming days, with the first effects expected for the next planting season in early 2019.

Gratitude for soil

Written by on December 5, 2018. Posted in Blogs.

On December 5, we celebrate World Soil Day. This year the theme is “Be the solution to soil pollution.” Most of you may not have been aware that such a day even existed or perhaps even question the reason why the world even dedicates an entire day to celebrate soil. The authors of this article are soil scientists; we have devoted our professional careers to studying soil. Perhaps we are biased, but we use this opportunity to enlighten readers with a greater appreciation for the importance of this thin layer of our planet we call soil.

Humankind has a conflicting relationship with soil. In English, “dirt” and “dirty” are synonyms for unclean, calling a man or a woman “dirty” is a terrible insult. A baby’s dirty diapers are said to be “soiled.” But if we dig deeper into human consciousness, we find a different story.

For Hindus, the Panchtatva defines the universal laws of life. Everything, including life, is composed of five basic elements: Akash, space or sky; Vayu, air; Jal, water; Agni, fire; and Prithvi, earth or soil. In the Judeo-Christian tradition, the first two human beings on the planet were Adam and Eve. In Hebrew, the original language of the Bible’s Old Testament, the name Adam means “earth” or “soil” and Eve means “life.” These images and symbols portray that human life originally derived from soil.

It gets even deeper: The English terms “human” and “humanity” are rooted in the Greek word “humus,” the fertile black topsoil.

When we use the words “soil” and “dirt” as derogatory terms, we literally define ourselves as soil. Soil is important and here are a few reasons why.

Soil is absolutely critical for the survival of our species and of all living life on the planet. Over 90 percent of all food produced in the world comes from soil and a greater percentage of the world’s freshwater passes through soil.

Arguably, climate change is the greatest threat to our species. Despite mitigation efforts by the global community, soil is frequently forgotten. However, soil holds roughly two and a half times the amount of carbon held in the atmosphere and in all of the plants and animals combined.

Soil is also the greatest reservoir of biodiversity on the planet. In one pinch of soil, there are over 1 billion individual organisms and 1 million unique species, most of which we know almost nothing about. In one handful of soil, there are more living organisms than the total number of human beings that have ever walked on the planet. As all of our antibiotics have been derived from soil microorganisms, the secrets to fighting all kinds of diseases are just under your feet.

In Nepal, soil is deeply interrelated with culture. From birth to death, Nepalese use soil in many rituals: naming ceremonies, birthday celebrations, soiling on Ashar 15, local healing and medicine, etc.

The government of Nepal has set ambitious targets for increasing the levels of organic matter in soil. This is essential to ensure that the soils that have sustained Nepali civilization for centuries will continue to sustain future generations. We need to encourage farmers and land managers in Nepal to maintain terracing on steeply sloped lands to protect against soil erosion. It is also important to appropriately use agrochemicals, such as pesticides and inorganic fertilizers, to improve soil health and crop productivity.

Soil has been polluted by heavy metals, effluents from chemical industries, indiscriminate use of agrochemicals, urbanization without proper planning, networking of roads without considering the carrying capacity of the soil and other factors. So let’s not overlook the importance of soil. We need to value the cleansing properties of soil, particularly riverine soils, and prevent these areas from continuing as the dumping grounds and sewers of Kathmandu and other cities.

On this day, the day when we celebrate soil, take a moment to look under your feet and marvel at the beauty and complexity of soil.

If we take care of our soils, our soils will take care of us.

New digital maps to support soil fertility management in Nepal

Written by on December 4, 2018. Posted in News.

KATHMANDU, Nepal (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) is working with Nepal’s Soil Management Directorate and the Nepal Agricultural Research Council (NARC) to aggregate historic soil data and, for the first time in the country, produce digital soil maps. The maps include information on soil PH, organic matter, total nitrogen, clay content and boron content. Digital soil mapping gives farmers and natural resource managers easy access to location-specific information on soil properties and nutrients, so they can make efficient and localized management decisions.

As part of CIMMYT’s Nepal Seed and Fertilizer (NSAF) project, researchers used new satellite imagery that enabled the resolution of the maps to be increased from 1×1 km to 250×250 m. They have updated the web portal to make it more user friendly and interactive. When loaded onto a smartphone, the map can retrieve the soil properties information from the user’s exact location if the user is within areas with data coverage. The project team is planning to produce maps for the whole country by the end of 2019.

CIMMYT scientist David Guerena talks about the role of the new digital maps to combat soil fertility problems in Nepal.

At a World Soil Day event in Nepal, CIMMYT soil scientist David Guerena presented the new digital soil maps to scientists, academics, policymakers and other attendees. Guerena explained the role this tool can play in combatting soil fertility problems in Nepal.

These interactive digital maps are not simply visualizations. They house the data and analytics which can be used to inform site-specific integrated soil fertility management recommendations.

The first high-resolution digital soil maps for the Terai region have been produced with support from the data assets from the National Land Use Project, developed by Nepal’s Ministry of Agriculture and Livestock Development. These maps will be used to guide field programming of the NSAF project, drive the development of market-led fertilizer products, and inform and update soil management recommendations. The government of Nepal can use the same information to align policy with the needs of farmers and the capacity of local private seed and fertilizer companies.

In 2017, 16 scientists from Nepal’s Soil Management Directorate, NARC and other institutions attended an advanced digital soil mapping workshop where they learned how to use different geostatistical methods for creating soil maps. This year, as part of the NSAF project, four NARC scientists attended a soil spectroscopy training workshop and learned about digitizing soil data management and using advanced spectral methods to convert soil information into fertilizer recommendations.

Soil data matters

Soil properties have a significant influence on crop growth and the yield response to management inputs. For farmers, having access to soil information can make a big difference in the adoption of integrated soil fertility management.

Farmer motivation and decision-making relies heavily on the perceived likeliness of obtaining a profitable return at minimized risk. This largely depends on the yield response to management inputs, such as improved seeds and fertilizers, which depends to a large extent on site-specific soil properties and variation in agro-ecological conditions. Therefore, quantitative estimates of the yield response to inputs at a given location are essential for estimating the risks associated with these investments.

The digital soil maps can be accessed at https://nsafmap.github.io/.

The Nepal Seed and Fertilizer project is funded by the United States Agency for International Development (USAID) and is a flagship project in Nepal. The objective of the NSAF is to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

New Soil Intelligence System for India provides high-quality data using modern analytics

Written by on December 4, 2018. Posted in Features.

NEW DELHI (CIMMYT) — The new Soil Intelligence System (SIS) for India will help the states of Andhra Pradesh, Bihar and Odisha rationalize the costs of generating high-quality soil data and build accessible geospatial information systems based on advanced geostatistics. The SIS initiative will rely on prediction rather than direct measurements to develop comprehensive soil information at scale. The resulting data systems will embrace FAIR access principles — findable, accessible, interoperable, and reproducible — to support better decision-making in agriculture.

SIS is a $2.5 million investment funded by the Bill & Melinda Gates Foundation. This initiative is led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with numerous partners including the International Food Policy Research Institute (IFPRI), World Soil Information (ISRIC), the Andhra Pradesh Space Applications Center (APSAC), and the state governments and state agriculture universities of Andhra Pradesh and Bihar. The initiative runs from September 2018 through February 2021.

“SIS will make important contributions towards leveraging soil information for decision-making in Indian agriculture by devising new soil health management recommendations,” explained Andrew McDonald, CIMMYT’s Regional Team Leader for Sustainable Intensification and Project Leader for the Cereal Systems Initiative for South Asia (CSISA). Researchers and scientists will combine mapping outputs with crop response and landscape reconnaissance data through machine-learning analytics to derive precise agronomy decisions at scale.

Farmers will be the primary beneficiaries of this initiative, as they will get more reliable soil health management recommendations to increase yields and profits. SIS will also be useful to state partners, extension and agricultural development institutions, the private sector and other stakeholders who rely on high-quality soil information. Through SIS, scientists and researchers will have an opportunity to receive training in modern soil analytics.

The SIS initiative aims to facilitate multi-institutional alliances for soil health management and the application of big data analytics to real-world problems. These alliances will be instrumental for initiating broader discussions at the state and national levels about the importance of robust data systems, data integration and the types of progressive access policies related to ‘agronomy at scale’ that can bring India closer to the Sustainable Development Goals.

Better soil analysis

Spectroscopy enables precise soil analysis and can help scientists identify appropriate preventive and rehabilitative soil management interventions. The technology is also significantly faster and more cost-effective than wide-scale wet chemistry-based soil analysis.

As part of the CSISA project, led by CIMMYT and funded by the Bill & Melinda Gates Foundation, two new soil spectroscopy labs were recently set up in Andhra Pradesh and Bihar, in collaboration with the state departments of agriculture. One lab is now operating at the Regional Agricultural Research Station (RARS) in Tirupati, Andhra Pradesh; and the other one at Bihar Agricultural University (BAU Sabour), in Bhagalpur, Bihar.

“The support from CIMMYT through the Gates Foundation will contribute directly to bringing down the cost of providing quality soil health data and agronomic advisory services to farmers in the long run,” said K.V. Naga Madhuri, Principal Scientist for Soil Science at Acharya N. G. Ranga Agricultural University. “We will also be able to generate precise digital soil maps for land use planning. The greatest advantage is to enable future applications like drones to use multi-spectral imagery and analyze rapidly large areas and discern changes in soil characteristics in a fast and reliable manner.”

Under the SIS initiative, soil spectroscopy results will be validated with existing gold standard wet chemistry methods. They will also be integrated with production practice data collected from the ground level, through new statistical tools.

Precise predictive models

Drawing information from a limited number of soil observations from a sample dataset, digital soil mapping (DSM) uses (geo)statistical models to predict the soil type or property for locations where no samples have been taken.

“These ‘unsampled locations’ are typically arranged on a regular grid,” explained Balwinder Singh, CIMMYT scientist and Simulation Modeler, “so DSM produces gridded — raster — soil maps at a specific spatial resolution — grid cell or pixel size — with a spatial prediction made for each individual grid cell.”

“Adopting DSM methods, combined with intelligent sampling design, could reduce the strain on the soil testing system in terms of logistics, quality control and costs,” noted Amit Srivastava, a geospatial scientist at CIMMYT. “Improving digital soil mapping practices can also help create the infrastructure for a soil intelligence system that can drive decision-making at scale.”

In partnership with state government agencies and the Bill & Melinda Gates Foundation, CIMMYT will continue to support the expansion of digital soil mapping and soil analysis capacity in India. The CSISA project and the SIS initiative are helping to deliver soil fertility recommendations to farmers, an important step towards the sustainable intensification of agriculture in South Asia.

CIMMYT drought tolerant maize: A key innovation for millions of farmers, says FAO

Written by Jérôme Bossuet on December 3, 2018. Posted in Features.

As climate experts forecast another climate-warming El Nino in early 2019, maize varieties developed under the Drought Tolerant Maize for Africa (DTMA) initiative represent low-cost innovations that could improve the crop’s climate resilience and the livelihoods of millions family farmers across Africa, according to the UN Food and Agriculture Organization (FAO).

Drought tolerant (DT) maize was among 20 success stories featured at the Innovation Fair of the International Symposium on Agricultural Innovation for Family Farmers, organized and hosted by FAO in Rome from 21 to 23 November, 2018. Drawing more than 500 participants from farmer associations, international organizations, United Nations agencies, governments, research institutions and the private sector, the Fair aimed to devise and recommend actions that unlock the potential of agricultural innovation.

Drought-tolerant seeds: An affordable and effective way to cope with dry weather

‘’Since early 1990s, farmers in Zimbabwe face erratic rains and maize crops often fail due to frequent droughts,’’ said Cosmos Magorokosho, maize breeder based at the Harare, Zimbabwe, office of the International Maize and Wheat Improvement Center (CIMMYT).

Led by CIMMYT, funded by the Bill & Melinda Gates Foundation and the Howard Buffett Foundation, and involving 13 national maize breeding programs and various seed companies across Africa, DTMA is responsible for more than 160 new maize varieties, including 15 in Zimbabwe that yield 25 to 30 percent more than conventional varieties under dry conditions and perform as well as those varieties under normal rainfall. The latter was crucial for convincing seed companies to take up and market DT maize, according to Magorokosho.

In one study in drought-prone southern Zimbabwe, farmers using the DT varieties in dry years were able to harvest up to 600 kilograms more maize per hectare — worth $240 and enough maize for 9 months for an average family of 6 people — than farmers who sowed conventional varieties. The added food security comes at no additional cost and, if farmers choose to sell the grain, it brings extra income for other household needs.

Under the Stress Tolerant Maize for Africa initiative, CIMMYT and partners are continuing to develop maize varieties that cope not only with drought but with common constraints such as insect pests, diseases including Maize Lethal Necrosis and infertile soils.

Public-private partnerships enable demand-driven innovation

Adopting new technology or practices can represent unacceptable risks for resource-poor farming families, who live without the official safety nets enjoyed by peers in prosperous economies and will simply starve if their crops fail. Involving farmers, seed companies and other end users in development is essential for agricultural innovations to be widely adopted and sustainable, according to Bram Govaerts, global director of innovative business strategies at CIMMYT.

“Dialogue with global food processing companies can create market opportunities for smallholder farmers through approaches like local, responsible sourcing,’’ said Govaerts, speaking during the fair’s panel ‘Engaging the private sector to accelerate agricultural innovation.’

“More than 3,300 Mexican farmers on more than 35,000 hectares in 5 states will benefit from responsible sourcing arrangements, whereby the companies pay them to grow the grain using sustainable farming practices,” Govaerts explained, adding that the farmers will supply an estimated 400,000 tons of grain to participating companies in the next 3 to 5 years.

Mexico’s Agriculture Department (SAGARPA) supports these and other public-private partnerships through its investments in MasAgro, which studies, develops and transfers innovative farming practices and technologies to the field, with emphasis on family farmers.

In September, the FAO’s Regional Office for Latin America and the Caribbean acknowledged MasAgro as a replicable and scalable initiative that could contribute significantly to sustainable rural development in that region.

These two impactful examples show that agricultural innovation can only succeed through well-thought research and development partnerships, and building such collaborations is a science in itself.
