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.

CIMMYT Joins the International Wheat Genome Sequencing Consortium

Written by Sarah McLaughlin on October 21, 2021. Posted in Press releases.

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.”

After release of the wheat genome reference sequence in 2018, the IWGSC entered Phase II with activities focused on developing tools to accelerate the development of improved varieties and to empower all aspects of basic and applied wheat science. The organization recently released versions 2.1 of the reference sequence assembly and annotation, and is continuing to work with the wheat community to improve the reference sequence by gap filling and integration of manual and functional annotation. The IWGSC also is focused on securing funding for a project that will ensure that “platinum-quality” sequences, representing the worldwide wheat diversity of landraces and elite varieties, are available publicly for breeders.

About the International Wheat Genome Sequencing Consortium

The IWGSC, with 3,300 members in 71 countries, is an international, collaborative consortium, established in 2005 by a group of wheat growers, plant scientists, and public and private breeders. The goal of the IWGSC is to make a high-quality genome sequence of bread wheat publicly available, in order to lay a foundation for basic research that will enable breeders to develop improved varieties. The IWGSC is a U.S. 501(c)(3) non-profit organization. To learn more, visit www.wheatgenome.org and follow us on Twitter, Facebook, LinkedIn and YouTube.

CIMMYT becomes partner of choice in PepsiCo and Grupo Trimex’s sustainability strategy

Written by Rodrigo Ordóñez on September 22, 2021. Posted in Press releases.

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

Written by Rodrigo Ordóñez on September 1, 2021. Posted in Press releases.

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

Written by Emma Orchardson on June 23, 2021. Posted in Press releases.

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.

ABOUT CIMMYT:

New integrated methodology supports inclusive and resilient global food systems transformation

Written by Rodrigo Ordóñez on June 4, 2021. Posted in Press releases.

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:

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;
Stakeholders determine a preferred future scenario based on assessment of national implications, and define drivers of change toward a desired scenario;
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;
Stakeholders agree on measurable targets and tangible, time-bound actions toward the preferred future scenario;
Stakeholders build shared commitment to a tactical implementation plan among traditional, non-traditional, and new partners;
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.

CIMMYT and John Innes Centre announce strategic collaboration on wheat research

Written by Rodrigo Ordóñez on April 29, 2021. Posted in Press releases.

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.

New project to recharge aquifers and cut water use in agriculture by 30 percent

Written by Rodrigo Ordóñez on April 22, 2021. Posted in Press releases.

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

Written by Rodrigo Ordóñez on April 9, 2021. Posted in Press releases.

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).

Investment in maize for Africa pays off

Written by Rodrigo Ordóñez on March 30, 2021. Posted in Press releases.

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.

Groundwater depletion in India could reduce winter cropped acreage significantly in years ahead

Written by Rodrigo Ordóñez on February 24, 2021. Posted in Press releases.

India is the world’s second-largest producer of wheat and rice and is home to more than 600 million farmers. The country has achieved impressive food-production gains since the 1960s, due in part to an increased reliance on irrigation wells, which allowed Indian farmers to expand production into the mostly dry winter and summer seasons.

But those gains have come at a cost: The country that produces 10% of the world’s crops is now the world’s largest consumer of groundwater, and aquifers are rapidly becoming depleted across much of India. Indian government officials have suggested that switching from groundwater-depleting wells to irrigation canals, which divert surface water from lakes and rivers, is one way to overcome projected shortfalls.

In a study published in the journal Science Advances, scientists conclude that a switch to canal irrigation will not fully compensate for the expected loss of groundwater in Indian agriculture.

The authors estimate that if Indian farmers lose all access to groundwater in overexploited regions, and if that irrigation water is not replaced with water from other sources, then winter cropped acreage could be reduced by up to 20% nationwide. However, that scenario seems highly unlikely and was included in the study only as an upper-bound estimate.

It seems more likely that any future groundwater shortfalls would be at least partially offset by increases in canal irrigation. But even if all Indian regions currently using depleted groundwater switch to canal irrigation, winter cropped acreage could still decline by 7% nationwide and by 24% in the most severely affected locations, according to the researchers.

Water alternatives needed

“Our results highlight the critical importance of groundwater for Indian agriculture and rural livelihoods, and we were able to show that simply providing canal irrigation as a substitute irrigation source will likely not be enough to maintain current production levels in the face of groundwater depletion,” said study lead author Meha Jain, an assistant professor at the University of Michigan’s School for Environment and Sustainability.

“We need coordinated efforts to solve this water availability and food security issue, which should be supported by science-led policy decisions on what strategies and technology solutions to scale out to improve irrigation efficiency,” said co-author Balwinder Singh, a Cropping Systems Simulation Modeler at the International Maize and Wheat Improvement Center (CIMMYT).

The study analyzed high-resolution satellite imagery and village-level census data and focused on winter cropped acreage. While nearly all Indian farmers plant crops during the monsoon to take advantage of seasonal rains, winter agriculture is mainly reliant on groundwater irrigation and now accounts for 44% of the country’s annual cropped acreage for food grains.

“These findings suggest that other adaptation strategies, in addition to canal expansion, are needed to cope with ongoing groundwater losses,” Jain said.

The possibilities include switching from winter rice to less water-intensive cereals, increased adoption of sprinklers and drip irrigation to conserve water in the fields, and policies to increase the efficiency of irrigation canals.

While groundwater depletion is becoming a global threat to food security, and the extent of current and projected groundwater depletion are well documented, the potential impacts on food production remain poorly quantified. The study is the first to use high-resolution empirical data, including census data about the irrigation methods used in more than 500,000 Indian villages, to estimate the crop production losses that may occur when overexploited groundwater is lost.

“Understanding the complex relationship between food security and water availability is crucial as we prepare for future rainfall variability due to global climate change,” said co-author Gillian Galford of the University of Vermont.

The proliferation of deep (>30 meters) irrigation wells called tube wells since the 1960s has enabled Indian farmers to increase the number of seasons when crops are planted in a given year. This increase in “cropping intensity” is credited for much of the country’s food-production gains.

The map on the right (B) shows projected winter cropped acreage losses if groundwater irrigation is replaced with canals, using national-level regression coefficients. (Graph: Jain et al. in Science Advances 2021)

Big data for food security

The researchers used satellite data to measure Indian winter cropped area, a key determinant of cropping intensity. They then linked the satellite data to census information about the three main types of irrigation infrastructure in India: shallow “dug wells,” deeper tube wells and canals that divert surface water.

Linking the two datasets allowed them to determine the relative efficacy of each irrigation method. That, in turn, enabled them to estimate potential future acreage losses and the ability of canal expansion to fill the gap.

The study’s worst-case scenario found that winter cropped area could decrease by up to 20% nationwide and by 68% in the most severely affected regions, if farmers lose all access to groundwater and if that irrigation water is not replaced from another source. The expected losses would largely occur in northwest and central India, according to the study.

The researchers also found that increased distance from existing irrigation canals is strongly associated with decreased acreage planted with winter crops. In the future, a greater reliance on canals could increase inequities related to irrigation access, according to the authors.

“This suggests that while canals may be a viable form of irrigation for those who live near canals, they may lead to more unequal access to irrigation across villages compared to wells, with negative impacts for those who live farther from canals,” the authors wrote.

In addition, the lakes and rivers that feed irrigation canals rise and fall in response to rainfall variability, unlike deep groundwater wells. So, a greater reliance on canal irrigation in the future would result in increased sensitivity to year-to-year precipitation fluctuations, as well as any long-term trends due to human-caused climate change.

The authors of the Science Advances study, in addition to Jain and Galford, are Ram Fishman of Tel Aviv University; Pinki Mondal of the University of Delaware; Nishan Bhattarai of the U-M School for Environment and Sustainability; Shahid Naeem, Upmanu Lall and Ruth DeFries of Columbia University; and Balwinder Singh of the International Maize and Wheat Improvement Center (CIMMYT).

The work was funded by a NASA New Investigator Award to Jain and two NASA Land Cover and Land Use Change grants, one awarded to R.S. DeFries and one to Jain.

Drought-tolerant maize project pioneers a winning strategy for a world facing climate change

Written by Rodrigo Ordóñez on February 24, 2021. Posted in Press releases.

Since the 1980s, the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA) have spearheaded the development and deployment of climate-smart maize in Africa.

This game-changing work has generated massive impacts for smallholder farmers, maize consumers, and seed markets in the region. It also offers a blueprint for CGIAR’s new 2030 Research and Innovation Strategy, which proposes a systems transformation approach for food, land and water systems that puts climate change at the center of its mission.

Over the course of the 10-year run of the first iteration of this collaborative work on climate-adaptive maize, the Drought Tolerant Maize for Africa (DTMA) project, CIMMYT and IITA partnered with dozens of national, regional, and private sector partners throughout sub-Saharan Africa to release around 160 affordable maize varieties. This month, CGIAR recognizes climate-smart maize as one of the standout 50 innovations to have emerged from the institution’s first half-century of work.

Game changer

Maize’s importance as a food crop in sub-Saharan Africa is hard to overstate. So are the climate change-driven challenges it faces.

It accounts for almost one third of the region’s caloric intake. It is grown on over 38 million hectares, primarily under rainfed conditions. Around 40% of this area faces occasional drought stress. Another 25% suffers frequent drought and crop losses reaching 50%.

Drought-tolerant maize stabilized production under drought-stress conditions. Recent studies show that farmers growing drought-tolerant maize varieties in dry years produced over a half ton more maize per hectare than those growing conventional varieties — enough maize to support a family of six for nine months.

Such drastic results fed increased demand for improved, climate-adaptive maize seed in sub-Saharan Africa, thus strengthening local commercial seed markets and helping drought-tolerant maize varieties reach an increasing share of climate-vulnerable farmers.

Today, approximately 8.6 million farmers have benefitted from CIMMYT- and IITA-derived climate-adaptive maize varieties in sub-Saharan Africa. Millions have risen above the poverty line.

In addition to drought-tolerance, CIMMYT- and IITA-derived climate-adaptive maize varieties have been developed to tolerate multiple climate-driven stresses and to provide improved nutritional outcomes through biofortification with essential nutrients such as provitamin A and zinc.

The task ahead

In his recently published book, How to Avoid a Climate Catastrophe, Bill Gates says “no other organization has done more than CGIAR to ensure that families — especially the poorest — have nutritious food to eat. And no other organization is in a better position to create the innovations that will help poor farmers adapt to climate change in the years ahead.”

CGIAR’s new strategic orientation is an important step towards making good on that potential. CIMMYT and IITA’s longstanding work on climate-smart maize offers an important blueprint for the kinds of bold, comprehensive, and collaborative research for development initiatives such a strategy could empower.

As CIMMYT and IITA directors general Martin Kropff and Nteranya Sanginga note in a recent op-ed, “The global battle against climate change and all its interconnected impacts requires a multisectoral approach to formulate comprehensive responses.”

FFAR grant develops climate-resilient wheat

Written by Rodrigo Ordóñez on January 11, 2021. Posted in Press releases.

Wheat constitutes 20% of all calories and protein consumed, making it a cornerstone of the human diet, according to the United Nations. However, hotter and drier weather, driven by a changing climate, threatens the global wheat supply. To address this threat, the Foundation for Food and Agriculture Research (FFAR) awarded a $5 million grant to the International Maize and Wheat Improvement Center (CIMMYT) to develop climate-resilient wheat. CIMMYT leads global research programs on maize and wheat, sustainable cropping systems and policies to improve farmers’ livelihoods. These activities have driven major gains in wheat variety improvement across the globe for decades; in the US alone, for example, over 50% of the wheat acreage is sown with CIMMYT-related varieties.

Wheat is among the most widely grown cereal crops in the world and the third-largest crop grown in the US by acre. Nearly all US wheat crops are improved and supported by public agriculture research. As most wheat in the US is dependent on rainfall and has no access to irrigation, this research is critical for helping the plants — and producers — weather climatic changes including extreme heat and drought. Additionally, the demand for wheat is expected to rise in the coming years — as much as 60% by 2050. Without public research, wheat production could decrease by nearly 30% over the same period due to extreme climate conditions.

“FFAR leverages public agriculture research funding through public-private partnerships to pioneer actionable research. With temperatures on the rise and water becoming scarcer, we are committed to supporting wheat farmers and providing new wheat varieties designed with future environmental challenges in mind,” said FFAR’s Executive Director Sally Rockey.

Using the FFAR grant, CIMMYT researchers are pioneering wheat breeding technologies to produce heat-tolerant, drought-resistant and climate-resilient wheat.

CIMMYT researchers and collaborators are applying cutting-edge approaches in genomics, remote sensing and big data analysis to develop new breeding technologies. A key intervention will explore the vast and underutilized reserve of wheat genetic resources to fortify the crop against current and future climate-related stresses.

“This project will help bridge a longstanding gap between state-of-the-art technological findings and crop improvement to deliver climate resilient wheat to farmers as quickly as possible,” said Matthew Reynolds, head of Wheat Physiology at CIMMYT and principal investigator of the project.

Breakthroughs from the FFAR funded project will achieve impact for growers via the International Wheat Improvement Network (IWIN) that supplies new wheat lines to public and private breeding programs worldwide, and has boosted productivity and livelihoods for wheat farmers for over half a century, especially in the Global South.

The research and breeding supported by FFAR will be conducted under the Heat and Drought Wheat Improvement Consortium (HeDWIC), a project led by CIMMYT in partnership with experts across the globe, designed to ensure wheat’s long-term climate resilience. Under the umbrella of the Wheat Initiative’s AHEAD unit, the most relevant advances in academia will be channeled to HeDWIC to help further boost impacts.

“‘Heat,’ ‘drought’ and ‘wheat’ are three of the most important words for billions of people,” said CIMMYT Interim Deputy Director for Research Kevin Pixley. “This partnership between CIMMYT and FFAR will help ensure that the best agricultural science is applied to sustainably raise production of one of the world’s most important staple crops, despite unprecedented challenges.”

CIMMYT Director General Martin Kropff said, “This project represents not only a breakthrough to develop wheat for the future, but also an emerging partnership between CIMMYT and FFAR. I look forward to a productive collaboration that will move us all closer to our mission of maize and wheat science for improved livelihoods.”

FFAR’s investment was matched by co-investments from the CGIAR Research Program on Wheat (WHEAT) and Accelerating Genetic Gains for Maize and Wheat (AGG), a project which is jointly funded by the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth, and Development Office (FCDO).

“Historic” release of six improved wheat varieties in Nepal

Written by Marcia MacNeil on December 15, 2020. Posted in Press releases.

On December 11, 2020, the Nepal Agricultural Research Council (NARC) announced the release of six new wheat varieties for multiplication and distribution to the country’s wheat farmers, offering increased production for Nepal’s nearly one million wheat farmers and boosted nutrition for its 28 million wheat consumers.

The varieties, which are derived from materials developed by the International Maize and Wheat Improvement Center (CIMMYT), include five bred for elevated levels of the crucial micronutrient zinc, and Borlaug 100, a variety well known for being high yielding, drought- and heat-resilient, and resistant to wheat blast, as well as high in zinc.

“Releasing six varieties in one attempt is historic news for Nepal,” said CIMMYT Asia Regional Representative and Principal Scientist Arun Joshi.

“It is an especially impressive achievement by the NARC breeders and technicians during a time of COVID-related challenges and restrictions,” said NARC Executive Director Deepak Bhandari.

“This was a joint effort by many scientists in our team who played a critical role in generating proper data, and making a strong case for these varieties to the release committee, ” said Roshan Basnet, head of the National Wheat Research Program based in Bhairahawa, Nepal, who was instrumental in releasing three of the varieties, including Borlaug 2020.

“We are very glad that our hard work has paid off for our country’s farmers,” said Dhruba Thapa, chief and wheat breeder at NARC’s National Plant Breeding and Genetics Research Centre.

Nepal produces 1.96 million tons of wheat on more than 750,000 hectares, but its wheat farmers are mainly smallholders with less than 1-hectare holdings and limited access to inputs or mechanization. In addition, most of the popular wheat varieties grown in the country have become susceptible to new strains of wheat rust diseases.

The new varieties — Zinc Gahun 1, Zinc Gahun 2, Bheri-Ganga, Himganga, Khumal-Shakti and Borlaug 2020 — were bred and tested using a “fast-track” approach, with CIMMYT and NARC scientists moving material from trials in CIMMYT’s research station in Mexico to multiple locations in Nepal and other Target Population of Environments (TPEs) for testing.

“Thanks to a big effort from Arun Joshi and our NARC partners we were able to collect important data in first year, reducing the time it takes to release new varieties,” said CIMMYT Head of Wheat Improvement Ravi Singh.

The varieties are tailored for conditions in a range of wheat growing regions in the country — from the hotter lowland, or Terai, regions to the irrigated as well as dryer mid- and high-elevation areas — and for stresses including wheat rust diseases and wheat blast. The five high-zinc, biofortified varieties were developed through conventional crop breeding by crossing modern high yielding wheats with high zinc progenitors such as landraces, spelt wheat and emmer wheat.

“Zinc deficiency is a serious problem in Nepal, with 21% of children found to be zinc deficient in 2016,” explained said CIMMYT Senior Scientist and wheat breeder Velu Govindan, who specializes in breeding biofortified varieties. “Biofortification of staple crops such as wheat is a proven method to help reverse and prevent this deficiency, especially for those without access to a more diverse diet.”

Borlaug 2020 is equivalent to Borlaug 100, a highly prized variety released in 2014 in adbMexico to commemorate the centennial year of Nobel Peace laureate Norman E. Borlaug. Coincidently, its release in Nepal coincides with the 50^th anniversary of Borlaug’s Nobel Peace Prize.

NARC staff have already begun the process of seed multiplication and conducting participatory varietal selection trials with farmers, so very soon farmers throughout the country will benefit from these seeds.

“The number of new varieties and record release time is amazing,” said Joshi. “We now have varieties that will help Nepal’s farmers well into the future.”

CIMMYT breeding of biofortified varieties was funded by HarvestPlus. Variety release and seed multiplication activities in Nepal were supported by NARC and the Asian Development Bank (ADB) through collaboration with ADB Natural Resources Principal & Agriculture Specialist Michiko Katagami. This NARC-ADB-CIMMYT collaboration was prompted by World Food Prize winner and former HarvestPlus CEO Howarth Bouis, and provided crucial support that enabled the release in a record time.
