Latin America and the Caribbean possess the largest reserve of arable land on the planet, 30% of renewable water, 46% of tropical forests and 30% of biodiversity. These resources represent an important contribution to the world’s food supply and other ecosystem services. However, climate change and natural disasters, exacerbated by COVID-19, have deteriorated economic and food security, destabilizing communities and causing unprecedented migration, impacting not only the region but the entire world.

Against this regional backdrop, AgriLAC Resiliente was created. This CGIAR Initiative seeks to increase the resilience, sustainability and competitiveness of the region’s agrifood systems and actors. It aims to equip them to meet urgent food security needs, mitigate climate hazards, stabilize communities vulnerable to conflict and reduce forced migration.

Guatemala was selected to present this Initiative, which will also impact farmers in Colombia, El Salvador, Honduras, Mexico, Nicaragua and Peru, and will be supported by national governments, the private sector, civil society, and regional and global donors and partners.

At a workshop on June 27–28, 2022, in Guatemala City, partners consolidated their collaboration by presenting the Initiative and developing a regional roadmap. Workshop participants included representatives from the government of Guatemala, NGOs, international cooperation programs, the private sector, producer associations, and other key stakeholders from the host country. Also at the workshop were the leaders from CGIAR research Centers involved in the Initiative, such as the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), the International Maize and Wheat Improvement Center (CIMMYT), the International Potato Center (CIP) and the International Food Policy Research Institute (IFPRI).

Impact through partnerships

“Partnerships are the basis for a future of food security for all through the transformation of food systems in the context of a climate crisis. AgriLAC’s goal of a coordinated strategy and regional presence will facilitate strong joint action with partners, donors, and producers, and ensure that CGIAR science continues to be leveraged so that it has the greatest possible impact,” said Joaquín Lozano, CGIAR Regional Director for Latin America and the Caribbean.

This Initiative is one of many CGIAR Initiatives in Latin America and consists of five research components: Climate and nutrition that seeks to use collaborative innovations for climate resilient and nutritious agrifood systems; Digital agriculture through the use of digital and inclusive tools for the creation of actionable knowledge; Low-emission competitiveness focused on agroecosystems, landscapes and value chains that are low in sustainable emissions; Innovation and scaling with the Innova-Hubs network for agrifood innovations and scaling; and finally, Science for timely decision making and establishment of policies, institutions, and investments for resilient, competitive and low-emission agrifood systems.

“We know the important role that smallholder farmers, both women and men, will play in the appropriation of the support tools that the Initiative will offer, which will allow them to make better decisions for the benefit of their communities. That is why one of the greatest impacts we expect from the project will be the contribution to gender equality, the creation of opportunities for youth, and the promotion of social inclusion,” said Carolina González, leader of the Initiative, from the Alliance of Bioversity International and CIAT.

Bram Govaerts, Director General of CIMMYT, said: “In Guatemala, we have had the opportunity to work side by side with farmers who today, more than ever, face the vicious circle of conflict, poverty and climate change. Through this Initiative, we hope to continue making progress in the transformation of agrifood systems in Central America, helping to make agriculture a dignified and satisfying job and a source of prosperity for the region’s producers.”

“I realize the importance of implementing strategic actions designed to improve the livelihoods of farmers. The environmental impact of development without sustainable planning puts at risk the wellbeing of humanity. The Initiatives of this workshop contribute to reducing the vulnerability of both productive systems and farmers and their families. This is an ideal scenario to strengthen alliances that allow for greater impact and respond to the needs of the country and the region,” said Jose Angel Lopez, Guatemala’s Minister of Agriculture, Livestock and Food.

National and regional strategies

AgriLAC Resiliente will also be presented in Honduras, where national partners will learn more about the Initiative and its role in achieving a resilient, sustainable, and competitive Latin America and the Caribbean, that will enable it to achieve the Sustainable Development Goals.

Under the general coordination of CGIAR, other Initiatives are also underway in Guatemala that will synergize with the global research themes toward the transformation of more resilient agrifood systems.

“We are committed to providing a structure that responds to national and regional priorities, needs, and demands. The support of partners, donors and producers will be key to building sustainable and more efficient agrifood systems,” Lozano said.

A generalized wiring diagram for wheat, as proposed by the authors. The diagram depicts the traits most commonly associated with the source (left) and sink (right) strengths and others that impact both the sink and source, largely dependent on growth stage (middle). TGW, thousand grain weight.

As crop yields are pushed closer to biophysical limits, achieving yield gains becomes increasingly challenging. Traditionally, scientists have worked on the premise that crop yield is a function of photosynthesis (source), the investment of assimilates into reproductive organs (sinks) and the underlying processes that enable and connect the expression of both. Although the original source-and-sink model remains valid, it must embrace more complexity, as scientific understanding improves.

A group of international researchers are proposing a new wiring diagram to show the interrelationships of the physiological traits that impact wheat yield potential, published on Nature Food. By illustrating these linkages, it shows connections among traits that may not have been apparent, which could serve as a decision support tool for crop scientists. The wiring diagram can inform new research hypotheses and breeding decisions, as well as research investment areas.

The diagram can also serve as a platform onto which new empirical data are routinely mapped and new concepts added, thereby creating an ever-richer common point of reference for refining models in the future.

“If routinely updated, the wiring diagram could lead to a paradigm change in the way we approach breeding for yield and targeting translational research,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the study. “While focused on yield potential, the tool can be readily adapted to address climate resilience in a range of crops besides wheat.”

Breeding milestone

The new wiring diagram represents a milestone in deterministic plant breeding. It dovetails simpler models with crop simulation models.

It takes into account how source and sink strengths may interact with wheat developmental stages to determine yield. For example, at the time of stem growth, spike growth or effective grain filling.

This diagram can be used to illustrate the relative importance of specific connections among traits in their appropriate phenological context and to highlight major gaps in knowledge. This graphical representation can also serve as a roadmap to prioritize research at other levels of integration, such as metabolomic or gene expression studies. The wiring diagram can be deployed to identify ways for improving elite breeding material and to explore untapped genetic resources for unique traits and alleles.

Yield for climate resilience

The wheat scientific community is hard at work seeking new ways to get higher yields more quickly to help the world cope with population growth, climate change, wars and stable supplies of calories and protein.

“To ensure food and nutritional security in the future, raising yields must be an integral component of making crops more climate-resilient. This new tool can serve as a roadmap to design the necessary strategies to achieve these goals,” said Jeff Gwyn, Program Director of the International Wheat Yield Partnership (IWYP).

Collaboration between food security institutions and research organizations has contributed to improvements in global grain production that have benefitted millions of farmers around the world – and must continue today. This message was highlighted during a ceremony hosted by the International Maize and Wheat Improvement Center (CIMMYT) to recognize the legacy of World Food Laureate and former CIMMYT Wheat Program Director Sanjaya Rajaram.

The ceremony, held at the CIMMYT Experimental Station in Toluca, State of Mexico, officially dedicated the Station in honor of Sanjaya Rajaram, honoring his memory as an “enemy of world hunger” and one of the scientists who has most contributed to global food security.

The Indian-born naturalized Mexican researcher, who was the third person from CIMMYT to receive the World Food Prize, was recognized for having developed more than 480 high-yielding and adaptable wheat varieties that have been planted on approximately 58 million hectares around the world.

“For this impressive achievement, which seems easy to summarize in one sentence, Raj became a giant of the ‘right to food’ and one of the fiercest enemies of hunger in the world,” said CIMMYT Director General Bram Govaerts.

“Building on the work of Dr. Norman Borlaug, Dr. Sanjaya Rajaram was a driving force in making CIMMYT into the extraordinary institution that it is today,” said Claudia Sadoff, Managing Director, Research Delivery and Impact of CGIAR, a global research partnership of which CIMMYT is a member.

“The challenges of today compel us to redouble our efforts to breed more resilient and more nutritious crops, as Dr. Sanjaya Rajaram did, Sadoff added. “This ceremony reminds us that Dr Rajaram’s legacy and the ongoing efforts of CIMMYT and CGIAR scientists must answer that.”

Awards for international cooperation in food security

At the event, CIMMYT presented awards to the Secretary of Foreign Affairs of Mexico, Marcelo Ebrard Casaubón, and of Secretary of Agriculture and Rural Development (SADER), Víctor Villalobos Arámbula, for their promotion of food security and social inclusion in Mexico and Latin America.

The Secretary of Foreign Affairs of Mexico expressed his gratitude for the Norman E. Borlaug and reaffirmed his commitment to “work in the international arena as we have done, but now we will have to work harder, with greater intensity.”

The Secretary of Agriculture and Rural Development of Mexico, Víctor Villalobos Arámbula, emphasized that Mexico, Latin America and CIMMYT play an important role in the struggle to improve the conditions of small-scale farmers and the resilience of agri-food systems, noting that more than 300,000 farmers grow maize, wheat and associated crops on over one million hectares in Mexico using sustainable technologies from the CIMMYT-led MasAgro project, now called Crops for Mexico.

“Throughout this administration,” he said, “we have designed, implemented and refined, through collaboration between SADER and CIMMYT, sustainable development strategies with a systemic approach that facilitates the participation of producers in more integrated and efficient value chains both in Mexico and in other countries.”

India’s Ambassador to Mexico, Pankaj Sharma, highlighted that his nation owes a large part of its Green Revolution to the “Sonora” wheat variety, which was developed in Mexico, a country that is considered one of the cradles of agriculture at a global level, with arable land accounting for 15 percent of the total land dedicated to agriculture in the world.

Report on the results of the Crops for Mexico initiative

CIMMYT’s Wheat Germplasm Bank Curator and Genotyping Specialist Carolina Sansaloni presented highlighted impacts from Crops for Mexico, the main cooperative project between the Government of Mexico — through the Secretary of Agriculture and Rural Development — and CIMMYT, and a flagship initiative in the application of technologies in sustainable agriculture.

The project has been in operation for more than a decade in 28 states in Mexico, with the collaboration of more than 100 national and international partners and private and public sector agencies in 12 regions, offering research infrastructure and training development for sustainable agronomic practices, she explained.

She reported that the results of 40 platforms, 500 demonstration modules and two thousand extension areas have an impact on more than one million hectares and benefit 300,000 maize, wheat and bean producers, with the use of high-yield varieties.

Rosalinda Muñoz Tafolla, a maize farmer in Amacuzac, in the Mexican state of Morelos, explained that her drive to produce healthy food led her to participate in Crops for Mexico, where CIMMYT’s support and advice has enabled her to dramatically increase her farm’s productivity while protecting the soil and conserving natural resources.

She explained that with the conservation agriculture system she learned to improve soil conditions, planted a new maize variety, and was supported in marketing her harvest at a good price and selling 2,000 maize ears (mostly weighing 200 grams each).

A new $25.7 million project, led by the International Maize and Wheat Improvement Center (CIMMYT), a Research Center part of CGIAR, the world’s largest public sector agriculture research partnership, is expanding the use of biodiversity held in the world’s genebanks to develop new climate-smart crop varieties for millions of small-scale farmers worldwide.

As climate change accelerates, agriculture will be increasingly affected by high temperatures, erratic rainfall, drought, flooding and sea-level rise. Looking to the trove of genetic material in genebanks, scientists believe they can enhance the resilience of food production by incorporating this diversity into new crop varieties — overcoming many of the barriers to fighting malnutrition and hunger around the world.

“Better crops can help small-scale farmers produce more food despite the challenges of climate change. Drought-resistant staple crops, such as maize and wheat, that ensure food amid water scarcity, and faster-growing, early-maturing varieties that produce good harvests in erratic growing seasons can make a world of difference for those who depend on agriculture. This is the potential for climate-adaptive breeding that lies untapped in CGIAR’s genebanks,” said Claudia Sadoff, Managing Director, Research Delivery and Impact, and Executive Management Team Convener, CGIAR.

Over five years, the project, supported by the Bill & Melinda Gates Foundation, aims to identify plant accessions in genebanks that contain alleles, or gene variations, responsible for characteristics such as heat, drought or salt tolerance, and to facilitate their use in breeding climate-resilient crop varieties. Entitled Mining useful alleles for climate change adaptation from CGIAR genebanks, the project will enable breeders to more effectively and efficiently use genebank materials to develop climate-smart versions of important food crops, including cassava, maize, sorghum, cowpea and rice.

The project is a key component of a broader initiative focused on increasing the value and use of CGIAR genebanks for climate resilience. It is one of a series of Innovation Sprints coordinated by the Agriculture Innovation Mission for Climate (AIM4C) initiative, which is led by the United Arab Emirates and the United States.

“Breeding new resilient crop varieties quickly, economically and with greater precision will be critical to ensure small-scale farmers can adapt to climate change,” said Enock Chikava, interim Director of Agricultural Development at the Bill & Melinda Gates Foundation. “This initiative will contribute to a more promising and sustainable future for the hundreds of millions of Africans who depend on farming to support their families.”

Over the past 40 years, CGIAR Centers have built up the largest and most frequently accessed network of genebanks in the world. The network conserves and makes nearly three-quarters of a million crop accessions available to scientists and governments. CGIAR genebanks hold around 10% of the world’s plant germplasm in trust for humanity, but account for about 94% of the germplasm distributed under the International Treaty on Plant Genetic Resources for Food and Agriculture, which ensures crop breeders globally have access to the fundamental building blocks of new varieties.

“This research to develop climate-smart crop varieties, when scaled, is key to ensuring that those hardest hit by climate shocks have access to affordable staple foods,” said Jeffrey Rosichan, Director of the Crops of the Future Collaborative of the Foundation for Food & Agriculture Research (FFAR). “Further, this initiative benefits US and world agriculture by increasing genetic diversity and providing tools for growers to more rapidly adapt to climate change.”

“We will implement, for the first time, a scalable strategy to identify valuable variations hidden in our genebanks, and through breeding, deploy these to farmers who urgently need solutions to address the threat of climate change,” said Sarah Hearne, CIMMYT principal scientist and leader of the project.

Building on ten years of support to CIMMYT from the Mexican government, CGIAR Trust Fund contributors and the United Kingdom’s Biotechnology and Biological Sciences Research Council (BBSRC), the project combines the use of cutting-edge technologies and approaches, high-performance computing, GIS mapping, and new plant breeding methods, to identify and use accessions with high value for climate-adaptive breeding of varieties needed by farmers and consumers.

New grafting technique could combat the disease threatening Cavendish bananas

Grafting is the technique of joining the shoot of one plant with the root of another, so they continue to grow together as one. Until now it was thought impossible to graft grass-like plants in the group known as monocotyledons because they lack a specific tissue type, called the vascular cambium, in their stem.

Researchers at the University of Cambridge have discovered that root and shoot tissues taken from the seeds of monocotyledonous grasses — representing their earliest embryonic stages — fuse efficiently. Their results are published today in the journal Nature.

An estimated 60,000 plants are monocotyledons; many are crops that are cultivated at enormous scale, for example rice, wheat and barley.

The finding has implications for the control of serious soil-borne pathogens including Panama Disease, or Tropical Race 4, which has been destroying banana plantations for over 30 years. A recent acceleration in the spread of this disease has prompted fears of global banana shortages.

“We’ve achieved something that everyone said was impossible. Grafting embryonic tissue holds real potential across a range of grass-like species. We found that even distantly related species, separated by deep evolutionary time, are graft compatible,” said Julian Hibberd in the University of Cambridge’s Department of Plant Sciences, senior author of the report.

The technique allows monocotyledons of the same species, and of two different species, to be grafted effectively. Grafting genetically different root and shoot tissues can result in a plant with new traits — ranging from dwarf shoots, to pest and disease resistance.

Alison Bentley, CIMMYT Global Wheat Program Director and a contributor to the report, sees great potential for the grafting method to be applied to monocot crops grown by resource-poor farmers in the Global South. “From our major cereals, wheat and rice, to bananas and matoke, this technology could change the way we think about adapting food security crops to increasing disease pressures and changing climates.”

The scientists found that the technique was effective in a range of monocotyledonous crop plants including pineapple, banana, onion, tequila agave and date palm. This was confirmed through various tests, including the injection of fluorescent dye into the plant roots — from where it was seen to move up the plant and across the graft junction.

“I read back over decades of research papers on grafting and everybody said that it couldn’t be done in monocots. I was stubborn enough to keep going — for years — until I proved them wrong,” said Greg Reeves, a Gates Cambridge Scholar in the University of Cambridge Department of Plant Sciences, and first author of the paper.

“It’s an urgent challenge to make important food crops resistant to the diseases that are destroying them,” Reeves explained. “Our technique allows us to add disease resistance, or other beneficial properties like salt-tolerance, to grass-like plants without resorting to genetic modification or lengthy breeding programmes.”

The world’s banana industry is based on a single variety, called the Cavendish banana — a clone that can withstand long-distance transportation. With no genetic diversity between plants, the crop has little disease-resilience. And Cavendish bananas are sterile, so disease resistance cannot be bred into future generations of the plant. Research groups around the world are trying to find a way to stop Panama Disease before it becomes even more widespread.

Grafting has been used widely since antiquity in another plant group called the dicotyledons. Dicotyledonous orchard crops — including apples and cherries, and high-value annual crops including tomatoes and cucumbers — are routinely produced on grafted plants because the process confers beneficial properties, such as disease resistance or earlier flowering.

The researchers have filed a patent for their grafting technique through Cambridge Enterprise. They have also received funding from Ceres Agri-Tech, a knowledge exchange partnership between five leading universities in the United Kingdom and three renowned agricultural research institutes.

“Panama disease is a huge problem threatening bananas across the world. It’s fantastic that the University of Cambridge has the opportunity to play a role in saving such an important food crop,” said Louise Sutherland, Director of Ceres Agri-Tech.

Ceres Agri-Tech, led by the University of Cambridge, was created and managed by Cambridge Enterprise. It has provided translational funding as well as commercialisation expertise and support to the project, to scale up the technique and improve its efficiency.

This research was funded by the Gates Cambridge Scholarship programme.

The International Wheat Genome Sequencing Consortium (IWGSC) is pleased to announce that the International Maize and Wheat Improvement Center (CIMMYT), has joined the organization as a sponsoring partner.

The IWGSC is an international, collaborative consortium of wheat growers, plant scientists, and public and private breeders dedicated to the development of genomic resources for wheat scientists and breeders to facilitate the production of wheat varieties better adapted to today’s challenges – climate change, food security and biodiversity preservation. In 2018, the IWGSC published the first genome reference sequence of the bread wheat, an essential tool to identify more rapidly genes and regulatory elements underlying complex agronomic traits such as yield, grain quality, resistance to diseases, and tolerance to stress such as drought or salinity.

The International Maize and Wheat Improvement Center, known by its Spanish acronym, CIMMYT, is a non-profit international agricultural research and training organization focusing on two of the world’s most important cereal grains: maize and wheat, and related cropping systems and livelihoods. CIMMYT’s maize and wheat research addresses challenges encountered by low-income farmers in the developing world including food and nutritional insecurity, environmental degradation, economic development, population growth and climate change.

CIMMYT’s Global Wheat Program is one of the most important public sources of high yielding, nutritious, disease- and climate-resilient wheat varieties for Africa, Asia, and Latin America. CIMMYT breeding lines can be found in varieties sown on more than 60 million hectares worldwide.

“I am truly pleased that CIMMYT has re-joined the IWGSC. The current reference sequences have been absolutely essential, enabling us to design new trait-based markers for use in CIMMYT wheat breeding pipelines. There remains much to explore in characterizing wheat at the whole genome level,” said CIMMYT wheat molecular breeding laboratory lead, Susanne Dreisigacker.

Sponsors are an essential part of the IWGSC. They participate in IWGSC-led projects and, as members of the Coordinating Committee, they help shape the IWGSC priorities, strategic plans, and activities. Susanne Dreisigacker will represent CIMMYT in the IWGSC Coordinating Committee.

“CIMMYT is a leading force in developing wheat varieties for southern countries,” said Kellye Eversole, Executive Director of the IWGSC. “We are thrilled that they are joining forces with the IWGSC to build the genomic tools and resources that will ensure growers around the world have access to resilient and highly productive wheat varieties.”

A new partnership announced today between the International Maize and Wheat Improvement Center (CIMMYT), PepsiCo and Grupo Trimex will greatly contribute to scale out sustainable farming practices in the central Mexican states of Guanajuato and Michoacán, which together form the country’s second wheat producing region.

The project Agriba Sustentable — a shortened reference for Bajío Sustainable Agriculture — will promote the adoption of conservation agriculture-based sustainable intensification practices among local farmers who will have access to PepsiCo’s wheat grain supply chain via Grupo Trimex.

“A part of the wheat that we use in Mexico for our products comes from the Bajío region,” said Luis Treviño, Director of Sustainability at PepsiCo Latin America. “However, agricultural production in the region has needs and areas of opportunity that we were able to identify thanks to the experience and deep knowledge that CIMMYT has developed over the years.”

Agriba Sustentable is the latest example of the new business models that CIMMYT is exploring as part of its integrated development approach to agri-food systems transformation, which seeks to engage multiple public, private and civil sector collaborators in cereals value chain development and enhancement efforts.

“The project’s specific goal is to improve the sustainability of the wheat production system in the Bajío region by enabling the adoption of technological innovations and sustainable production practices among at least 200 farmers in the Grupo Trimex supply chain during the first year of implementation, and to gradually scale out to reach many more farmers,” said Bram Govaerts, Director General of CIMMYT.

CIMMYT’s long-term field trials in Mexico have shown that conservation agriculture-based sustainable intensification practices raise wheat yields by up to 15% and cut greenhouse gas emissions by up to 40%.

“The farming practices that CIMMYT promotes reduce environmental impact,” said Mario Ruiz, Sourcing Manager of Grupo Trimex. “Conservation agriculture can cut CO2 emissions by up to 60% from reduced diesel consumption, lower fuel use by up to 70% and water consumption by 30%.”

According to PepsiCo Mexico, Agriba Sustentable is an important step for its global vision PepsiCo Positive (pep+), which seeks to offset its agricultural footprint by promoting sustainable farming on 2.8 million hectares globally. The plan also aims to improve the livelihoods of 250,000 people who are part of their global agricultural supply chain and to source sustainably 100% of the company’s key ingredients by 2030.

Nitrogen-efficient wheats can provide more food with fewer greenhouse gas emissions, new study shows

An international collaboration has discovered and transferred to elite wheat varieties a wild-grass chromosome segment that causes roots to secrete natural inhibitors of nitrification, offering a way to dial back on heavy fertilizer use for wheat and to reduce the crop’s nitrogen leakage into waterways and air, while maintaining or raising its productivity and grain quality, says a new report in the Proceedings of the National Academy of Sciences of the United States of America.

Growing wheat varieties endowed with the biological nitrification inhibition (BNI) trait could increase yields in both well-fertilized and nitrogen-poor soils, according to G.V. Subbarao, researcher at the Japan International Research Center for Agricultural Sciences (JIRCAS) and first author of the new report.

“Use of wheat varieties that feature BNI opens the possibility for a more balanced and productive mix of nitrogen nutrients for wheat fields, which are currently dominated by highly-reactive nitrogen compounds that derive in large part from synthetic fertilizers and can harm the environment,” Subbarao said.

The most widely grown food crop on the planet, wheat is consumed by over 2.5 billion people in 89 countries. Nearly a fifth of the world’s nitrogen-based fertilizer is deployed each year to grow wheat but, similar to other major cereals, vegetables, and fruits, the crop takes up less than half of the nitrogen applied.

Much of the remainder is either washed away, contaminating ground waters with nitrate and contributing to algae blooms in lakes and seas, or released into the air, often as nitrous oxide, a greenhouse gas 300 times more potent than carbon dioxide.

The study team first homed in on the chromosome region associated with the strong BNI capacity in the perennial grass species Leymus racemosus and moved it from the grass, using “wide crossing” techniques, into the cultivar Chinese Spring, a wheat landrace often used in genetic studies. From there, they transferred the BNI chromosome sequence into several elite, high-yielding wheat varieties, leading to a near doubling of their BNI capacity, as measured through lab analyses of soil near their roots.

The new wheats — elite varieties from the International Maize and Wheat Improvement Center (CIMMYT) into which the BNI trait was cross-bred — greatly reduced the action of soil microbes that usually convert fertilizer and organic nitrogen substances into ecologically-harmful compounds such as nitrous oxide gas, according to Hannes Karwat, a CIMMYT post-doctoral fellow and study co-author.

“The altered soil nitrogen cycle was even reflected in the plants’ metabolism,” Karwat said, “resulting in several responses indicative of a more balanced nitrogen uptake in the plants.”

The scientists involved said BNI-converted wheats in this study also showed greater overall biomass and grain yield, with no negative effects on grain protein levels or breadmaking quality.

“This points the way for farmers to feed future wheat consumers using lower fertilizer dosages and lowering nitrous oxide emissions,” said Masahiro Kishii, a CIMMYT wheat cytogeneticist who contributed to the research. “If we can find new BNI sources, we can develop a second generation of elite wheat varieties that require even less fertilizer and that better deter nitrous oxide emissions.”

A recent PNAS paper by Subbarao and Princeton University scientist Timothy D. Searchinger mentions BNI as a technology that can help foster soils featuring a more even mix of nitrogen sources, including more of the less-chemically-reactive compound ammonium, a condition that can raise crop yields and reduce nitrous oxide emissions.

Scale out to slow global warming?

The present study comes just as the Intergovernmental Panel on Climate Change (IPCC) has released its Sixth Assessment Report, which among other things states that “… limiting human-induced global warming … requires limiting cumulative CO2 emissions … along with strong reductions in other greenhouse gas emissions.”

Globally, 30% of greenhouse gas emissions come from agriculture. BNI-enabled wheat cultivars can play an important role to reduce that footprint. Wheat-growing nations that have committed to the Paris Climate Accord, whose provisions include reducing greenhouse gas emissions 30% by 2050, could be early adopters of the BNI technology, together with China and India, the world’s top two wheat producers, according to Subbarao.

“This work has demonstrated the feasibility of introducing BNI-controlling chromosome segments into modern wheats, without disrupting their yields or quality,” said Subbarao. “To realize the technology’s full potential, we need to transfer the BNI feature into many elite varieties adapted to diverse wheat growing areas and to assess their yield in many farm settings and with varying levels of soil pH, fertilization and water use.”

A project to establish nitrogen-efficient wheat production systems in the Indo-Gangetic Plains using BNI has recently been approved by Japan and is under way, with the collaboration of JIRCAS, the Indian Council of Agricultural Research (ICAR), and the Borlaug Institute of South Asia (BISA). Under the project, BNI-converted wheat lines developed from JIRCAS-CIMMYT partnerships will be tested in India and the BNI trait transferred to popular national wheat varieties.

“The BNI-technology is also featured in Green Technology, a Japanese government policy document for moving towards a zero-carbon economy,” said Osamu Koyama, President of JIRCAS, which has also posted a note about the new PNAS study. JIRCAS and CGIAR BNI research is co-funded by the Ministry of Agriculture, Forestry and Fisheries of Japan.

“Adaptation and mitigation solutions such as BNI, which help lessen the footprint of food production systems, will play a large role in CGIAR research-for-development, as part of One CGIAR Initiatives starting in 2022,” said Bram Govaerts, CIMMYT Director General.

Bangladesh could largely reduce greenhouse gas emissions from agriculture while increasing efficiency in production

A number of readily-available farming methods could allow Bangladesh’s agriculture sector to decrease its greenhouse gas emissions while increasing productivity, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) and partners.

The study, published in Science of the Total Environment, measured the country’s emissions due to agriculture, and identified and analyzed potential mitigation measures in crop and livestock farming. Pursuing these tactics could be a win-win for farmers and the climate, and the country’s government should encourage their adoption, the research suggests.

“Estimating the greenhouse gas emissions associated with agricultural production processes — complemented with identifying cost-effective abatement measures, quantifying the mitigation scope of such measures, and developing relevant policy recommendations — helps prioritize mitigation work consistent with the country’s food production and mitigation goals,” said CIMMYT climate scientist Tek Sapkota, who led this work.

To determine Bangladesh’s agricultural greenhouse gas emissions, the researchers analyzed 16,413 and 12,548 datapoints from crops and livestock, respectively, together with associated soil and climatic information. The paper also breaks down the emissions data region by region within the country. This could help Bangladesh’s government prioritize mitigation efforts in the places where they will be the most cost-effective.

“I believe that the scientific information, messages and knowledge generated from this study will be helpful in formulating and implementing the National Adaptation Plan (NAP) process in Bangladesh, the National Action Plan for Reducing Short-Lived Climate Pollutants (SLCPs) and Nationally Determined Contributions (NDC),” said Nathu Ram Sarker, director general of the Bangladesh Livestock Research Institute.

Policy implications

Agriculture in Bangladesh is heavily intensified, as the country produces up to three rice crops in a single year. Bangladesh also has the seventh highest livestock density in the world. In all, the greenhouse gas output of agriculture in Bangladesh was 76.79 million metric tons of carbon dioxide equivalent (Mt CO2e) in 2014-15, according to the research. This emission is equivalent to the emission from fossil fuel burning by 28 million cars for a year.  At the going rate, total agricultural emission from Bangladesh are expected to reach 86.87 Mt CO2e by 2030, and 100.44 Mt CO2e by 2050.

By deploying targeted and often readily-available methods, Bangladesh could mitigate 9.51 Mt and 14.21 Mt CO2e from its agriculture sector by 2030 and 2050, respectively, according to the paper. Further, the country can reach three-fourths of these outcomes by using mitigation strategies that also cut costs, a boon for smaller agricultural operations.

Adopting these mitigation strategies can reduce the country’s carbon emissions while contributing to food security and climate resilience in the future. However, realizing the estimated potential emission reductions may require support from the country’s government.

“Although Bangladesh has a primary and justified priority on climate change adaptation, mitigation is also an important national priority. This work will help governmental policy makers to identify and implement effective responses for greenhouse gas mitigation from the agricultural sector, with appropriate extension programs to aid in facilitating adoption by crop and livestock farmers,” said Timothy Krupnik, CIMMYT country representative in Bangladesh and coauthor of the paper.

Mitigation strategies

The research focused on eight crops and four livestock species that make up the vast majority of agriculture in Bangladesh. The crops — potato, wheat, jute, maize, lentils and three different types of rice — collectively cover more than 90% of cultivated land in the nation. Between 64 and 84% of total fertilizer used in Bangladesh is used to cultivate these crops. The paper also focuses on the four major kinds of livestock species in the country: cattle, buffalo, sheep and goats.

For crops, examples of mitigation strategies include alternate wetting and drying in rice (intermittently irrigating and draining rice fields, rather than having them continuously flooded) and improved nutrient use efficiency, particularly for nitrogen. The research shows that better nitrogen management could contribute 60-65% of the total mitigation potential from Bangladesh’s agricultural sector. Other options include adopting strip-tillage and using short duration rice varieties.

For livestock, mitigation strategies include using green fodder supplements, increased concentrate feeding and improved forage/diet management for ruminants. Improved manure storage, separation and aeration is another potential tool to reduce greenhouse gas emissions. The mitigation options for livestock would make up 22 and 28% of the total potential emission reductions in the sector by 2030 and 2050, respectively.

New integrated methodology supports inclusive and resilient global food systems transformation

A multi-disciplinary team of agricultural researchers and development practitioners is proposing a new approach to tackle the shortcomings of global food production systems that degrade the environment, greatly contribute to climate change and fail to deliver healthy diets for a growing population.

The new methodology developed by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) aims to transform national food systems by achieving consensus between multiple stakeholders and building on successful participatory agricultural research experiences.

According to a peer-reviewed paper published today in the journal PLOS ONE, the Integrated Agri-food System Initiative (IASI) “is designed to generate strategies, actions, and quantitative, [Sustainable Development Goals] SDGs-aligned targets that have [a significant] likelihood of supportive public and private investment”.

The IASI methodology is based on successful integrated development projects implemented by CIMMYT in Mexico and Colombia, the latter in partnership with the Alliance Bioversity-CIAT, which engaged multiple public, private and civil sector collaborators in local maize systems enhancement. These initiatives took advantage of sociopolitical “windows of opportunity” that helped build multiple stakeholder consensus around health, nutrition, food security and development aspirations in both countries.

“CIMMYT’s integrated development approach to maize systems transformation in Mexico and Colombia laid the foundations of the IASI methodology by overcoming government transitions, annual budget constraints and win-or-lose rivalry between stakeholders in favor of equity, profitability, resilience and sustainability,” said Bram Govaerts, chief operating officer and Integrated Development Program director at CIMMYT.

Ultimately, the IASI methodology offers public officials and development practitioners the possibility to transform food systems by scaling out innovative farming practices and technologies that lead to sustainably managed natural resources and improved nutrition and food security.

The main steps to implement the IASI methodology are:

  1. Diverse experts examine the current status and the business-as-usual scenario based on analysis of the socioeconomic, political, and sectoral context and model-based projections;
  2. Stakeholders determine a preferred future scenario based on assessment of national implications, and define drivers of change toward a desired scenario;
  3. Defined criteria are applied to stakeholder and expert inputs to validate drivers of change and to identify strategies and actions — for example, public policies, value chain and market interventions, and biotechnology applications — that can steer toward the preferred future scenario, which are then reviewed and prioritized by high-level decision makers;
  4. Stakeholders agree on measurable targets and tangible, time-bound actions toward the preferred future scenario;
  5. Stakeholders build shared commitment to a tactical implementation plan among traditional, non-traditional, and new partners;
  6. Ongoing stakeholder engagement is organized around an online dashboard that tracks actions and progress toward targets and supports course correction and coordinated investment.

Following these steps, the authors of the IASI methodology propose to build a “global food systems transformation network” to co-design and co-implement agricultural development projects that bring together multiple partners and donors for global agricultural systems transformation.

As the approach is refined and further applications are built, it is expected that this network will harness efforts to initiate a new field of research and global practice on “integrated methodologies for food system transformation and innovation” — analogous to the fields of business administration and organizational development.

IASI serves as the backbone of new CGIAR Regional Integrated Initiatives, which draw on capacities from regional international agricultural research centers and programs to deliver global agri-food system transformation.

The International Maize and Wheat Improvement Center (CIMMYT) and the John Innes Centre (JIC) have announced a strategic collaboration for joint research, knowledge sharing and communications, to further the global effort to develop the future of wheat.

Wheat, a cornerstone of the human diet that provides 20% of all calories and protein consumed worldwide, is threatened by climate change-related drought and heat, as well as increased frequency and spread of pest and disease outbreaks. The new collaboration, building on a history of successful joint research achievements, aims to harness state-of-the-art technology to find solutions for the world’s wheat farmers and consumers.

“I am pleased to formalize our longstanding partnership in wheat research with this agreement,” said CIMMYT Deputy Director General for Research Kevin Pixley. “Our combined scientific strengths will enhance our impacts on farmers and consumers, and ultimately contribute to global outcomes, such as the Sustainable Development Goal of Zero Hunger.”

Director of the John Innes Centre, Professor Dale Sanders commented, “Recognizing and formalizing this long-standing partnership will enable researchers from both institutes to focus on the future, where the sustainable development of resilient crops will benefit a great many people around the world.”

Thematic areas for collaboration

Scientists from CIMMYT and JIC will work jointly to apply cutting-edge approaches to wheat improvement, including:

  • developing and deploying new molecular markers for yield, resilience and nutritional traits in wheat to facilitate deploying genomic breeding approaches using data on the plant’s genetic makeup to improve breeding speed and accuracy;
  • generating, sharing and exploiting the diversity of wheat genetic material produced during crossing and identified in seed banks;
  • pursuing new technologies and approaches that increase breeding efficiency to introduce improved traits into new wheat varieties; and
  • developing improved technologies for rapid disease diagnostics and surveillance.

Plans for future collaborations include establishing a new laboratory in Norwich, United Kingdom, as part of the Health Plants, Healthy People, Healthy Plant (HP3) initiative.

Bringing innovations to farmers

An important goal of the collaboration between CIMMYT and JIC is to expand the impact of the joint research breakthroughs through knowledge sharing and capacity development. Stakeholder-targeted communications will help expand the reach and impact of these activities.

“A key element of this collaboration will be deploying our innovations to geographically diverse regions and key CIMMYT partner countries that rely on smallholder wheat production for their food security and livelihoods,” said CIMMYT Global Wheat Program Director Alison Bentley.

Capacity development and training will include collaborative research projects, staff and student exchanges and co-supervision of graduate students, exchange of materials and data, joint capacity building programs, and shared connections to the private sector. For example, plans are underway for a wheat improvement summer school for breeders in sub-Saharan African countries and an internship program to work on the Mobile And Real-time PLant disease (MARPLE) portable rust testing project in Ethiopia.

The International Maize and Wheat Improvement Center (CIMMYT) announced a new three-year public–private partnership with the German development agency GIZ and the beverage company Grupo Modelo (AB InBev) to recharge aquifers and encourage water-conserving farming practices in key Mexican states.

The partnership, launched today, aims to contribute to a more sustainable use of water in agriculture. The project will promote sustainable farming and financing for efficient irrigation systems in the states of Hidalgo and Zacatecas, where Grupo Modelo operates. CIMMYT’s goal is to facilitate the adoption of sustainable intensification practices on more than 4,000 hectares over the next three years, to reduce the water footprint of participant farmers.

Mexico is at a high risk of facing a water crisis in the next few years, according to the World Resources Institute. The country needs to urgently begin reducing its use of available surface and ground water supplies if it is to avert the looming crisis.

Farming accounts for nearly 76% of Mexico’s annual water consumption, as estimated by Mexico’s Water Commission (CONAGUA). Farmers, therefore, have a key role to play in a more sustainable use of this valuable natural resource.

“We need to take care of the ecosystem and mitigate agriculture’s impact on the environment to address climate change by achieving more sustainable agri-food systems,” said Bram Govaerts, chief operating officer, deputy director general of research a.i. and director of the Integrated Development program at CIMMYT.

The project, called Aguas Firmes (Spanish for “Firm Waters”), also seeks to recharge two of Mexico’s most exploited aquifers, by restoring forests and building green infrastructure.

“Our priority is water, which is the basis of our business but, above all, the substance of life,” said Cassiano De Stefano, chair of Grupo Modelo, one of the Mexico’s leading beer companies. “We’ve decided to lead by example by investing considerably in restoring two aquifers that are essential to Zacatecas and Hidalgo’s development.”

The German development agency GIZ, one of CIMMYT’s top funders, is also investing in this alliance that will benefit 46,000 farmers in Hidalgo and 700,000 farmers in Zacatecas.

“We are very proud of this alliance for sustainable development that addresses a substantial problem in the region and strengthens our work on biodiversity conservation and sustainable use of natural resources in Mexico,” said Paulina Campos, Biodiversity director at GIZ Mexico.

CIMMYT undertakes participatory agricultural research activities with local farmers to collaboratively develop and implement sustainable farming practices and technologies that help reduce water consumption in grain production by up to 30%.

On-farm nitrogen management practices have global reverberations

An international team of scientists has strengthened our understanding of how better fertilizer management could help minimize nitrous oxide (N2O) emissions while still achieving high crop yields in the new publication: Meta-analysis of yield and nitrous oxide outcomes for nitrogen management in agriculture. This research was conducted through a meta-analysis, where the results of multiple scientific studies were statistically combined.

To meet the world’s growing demand for food, farmers need fertile soil. Nitrogen, an essential element in plant fertilizer, can have extremely deleterious effects on the environment when not managed effectively. Numerous studies have confirmed that improving nitrogen use in agriculture is key to securing a food secure future and environmental sustainability.

“Society needs nuanced strategies based upon tailored nutrient management approaches that keep nitrogen balances within safe limits,” said Tai M Maaz, researcher at University of Hawaii at Manoa and lead author of the study.

When farmers apply nitrogen fertilizer to their crop, typically only 30-40% of it is taken up by the plant and the rest is lost the the environment. One byproduct is  nitrous oxide (N2O), one of the most potent greenhouse gases in the atmosphere. Global agriculture is a major contributor of greenhouse gas emissions, especially those derived from nitrous oxide emissions.

Although farmers are now commonly told to practice fertilizer rate reduction, or simply put, to apply less fertilizer, there are cases where that strategy is either not possible or not advisable.

Alternative predictors of emissions

The study found that output indicators such as partial nitrogen balance (PNB), an indicator for the amount of nitrogen prone to loss, and partial factor productivity (PFP), a measure of input-use efficiency, predicted nitrous oxide emissions as well as or better than the application rate alone. This means that in some cases, where nitrogen rate reduction is not possible, nitrous oxide emission can still be reduced by increasing yield through implementation of improved fertilizer management practices, such as the “4Rs:” right source, right timing, right placement and right application rate.

Tek B Sapkota, climate scientist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study, emphasized that “rate reduction is still important in the cropping systems where the current level of nitrogen application is excessively high. But, when comparing the systems at the same nitrogen application rates, nitrous oxide emission can be reduced by increasing yield.”

“The 4R nutrient management practices must be tailored to specific regions to help close yield gaps and maintain environmental sustainability: the win-win scenario. The future will require public and private institutions working together to disseminate such nutrient management information for specific cropping systems in specific geographies,” said Sapkota, who is also a review editor of the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report.

The article was a collaborative effort from the International Maize and Wheat Improvement Center (CIMMYT), the University of Hawaii, the Environmental Defense Fund, Plant Nutrition Canada and the African Plant Nutrition Institute. It was funded by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).

Between 1995-2015, nearly 60% of all maize varieties released in 18 African countries were CGIAR-related. At the end of this period, in 2015, almost half of the maize area in these countries grew CGIAR-related maize varieties. All that was accomplished through modest, maximum yearly investment of about $30 million, which showed high returns: in 2015, the aggregate yearly economic benefits for using CGIAR-related maize varieties released after 1994 were estimated to be between $660 million and $1.05 billion.

These are just some of the key findings of Impacts of CGIAR Maize Improvement in sub-Saharan Africa, 1995-2015 a new, comprehensive review of the two decades of longstanding, CGIAR-led work on improved maize for Africa.

A staple concern

Since its introduction to Africa in the 16th century, maize has become one of the most important food crops in the continent.

It accounts for almost a third of the calories consumed in sub-Saharan Africa. And it’s grown on over 38 million hectares in the region, mostly by rainfall-dependent smallholder farmers.

Climate change poses an existential threat to the millions who depend on the crop for their livelihood or for their next meal. Already 65% of the maize growing areas in sub-Saharan Africa face some level of drought stress.

Long-term commitment

Through the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA), CGIAR has been working alongside countless regional partners since 1980s to develop and deploy climate-smart maize varieties in Africa.

This work builds on various investments including Drought-Tolerant Maize for Africa (DTMA) and Stress Tolerant Maize for Africa (STMA). Support for this game-changing work has generated massive impacts for smallholder farmers, maize consumers, and seed markets in the region. Throughout, the determination to strengthen the climate resilience of maize agri-food systems in Africa has remained the same.

To understand the impact of their work — and how to build on it in the coming years — researchers at CIMMYT and IITA took a deep dive into two decades’ worth of this work across 18 countries in sub-Saharan Africa. These findings add to our understanding of the impact of work that today benefits an estimated 8.6 million farmers in the region.

Big challenges remain. But with the right partnerships, know-how and resources we can have an outsize impact on meeting those challenges head on.
