New innovative crops could significantly reduce agriculture’s climate change impact and environmental footprint

Written by Julian Bañuelos-Uribe on June 4, 2024. Posted in Press releases.

As the global population approaches the 10 billion mark, the reliance on fertilisers to boost agricultural production has become an essential, yet environmentally challenging, practice. A Century-long dependence on these additives has allowed food production to keep pace with the growth in human population. However, the use of fertilisers across various farming systems is now causing severe ecological stress. The leaching of nitrogen into natural ecosystems, coupled with the release of greenhouse gases, is pushing the Earth’s environmental limits to a critical threshold.

To address this, an ambitious new research initiative aims to shrink the nitrogen footprint of agriculture by developing a breakthrough technology based on nature’s own solutions: a natural process called biological nitrification inhibition (BNI). The Novo Nordisk Foundation has awarded CIMMYT a grant of up to USD 21.1 million to lead an innovation research initiative called CropSustaiN that is designed to reduce the nitrogen footprint of wheat cultivation.

“Success in this initiative could lead to a major shift in agricultural practices globally, benefiting both the planet and farmers’ livelihoods. In addition to using less fertiliser, cost for the farmer will be minimal because all the components are already in the seed. This initiative could, potentially, be extended from wheat cultivation to include other staple crops like maize and rice,” says Claus Felby, Senior Vice President, Biotech, Novo Nordisk Foundation.

“BNI could be a part of how we revolutionise nitrogen management in agriculture. It represents a genetic mitigation strategy that not only complement existing methods but also has the potential to decrease the need for synthetic fertilisers substantially. The mitigation potential of better nitrogen fertiliser management could be as impactful for the Global South as the Green Revolution,” explains Bram Govaerts, Director General, CIMMYT.

Revolutionary mitigation approach

Rooted in a seed-based genetic strategy, BNI leverages a plant’s innate ability to suppress soil nitrification through the release of natural compounds. This approach potentially promises to curb the use and leaching of synthetic nitrogen fertilisers—a significant contributor to greenhouse gas emissions and water pollution—without compromising wheat yield or soil vitality. The BNI-method contrasts with synthetic nitrification inhibitors and could offer a more scalable and cost-effective solution, potentially reducing nitrogen fertiliser usage by 20%, depending on regional farming conditions.

By harnessing the power of genetics in plant seeds, CropSustaiN leverages the natural process of BNI to develop new wheat varieties that require significantly less nitrogen fertiliser. Using conventional breeding, genes from wild crop relatives like wild rye, which have inherently better nitrogen use efficiency, are incorporated. CIMMYT makes such breeding products available to its global network of partners for the international public good.

The agenda for CropSustaiN includes validating BNI efficacy across diverse climates and integrating the technology into mainstream agricultural protocols. While the venture carries success risks, the potential rewards—ranging from widespread BNI adoption to valuable insights into nitrogen management—position it as a pioneering initiative. By ensuring that the seeds developed through this program are accessible to all farmers without exclusive patent rights, the Novo Nordisk Foundation is leading an inclusive approach to agricultural innovation.

CropSustaiN builds on the joint research by the Japan International Research Center for Agricultural Sciences (JIRCAS) and CIMMYT that started in 2015. The initiative has already yielded BNI wheat lines tested over three farming seasons. These innovative crops are now poised for further development and for scaling worldwide, indicating a potential paradigm shift in agricultural practices.

The Novo Nordisk Foundation has already laid the groundwork for CropSustaiN by funding related BNI research at CIMMYT, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Aarhus University, the University of Aberdeen, and the University of Copenhagen -thus fostering an ecosystem for research innovation.

In Ethiopia, regional and local representatives endorse national framework on climate services

Written by mcallejas on October 27, 2023. Posted in News.

In Ethiopia, regional government representatives endorsed in October 2023 the National Framework on Climate Services (NFCS), a tool designed to guide the establishment and delivery of climate services in key sectors: water and energy, agriculture, health, disaster risk management, and environmental protection.

This endorsement by regional state representatives marks an important step towards the implementation at regional and zonal levels of the NFCS, which was adopted at the national level in 2020.

The adoption of the Framework concluded a two-day workshop organized by the Ethiopian Meteorological Institute in partnership with CIMMYT through the AICCRA project, which aims to scale climate-smart agriculture and climate information services for the benefit of millions of small-scale farmers in Ethiopia. The workshop was also attended by ministers, state ministers and heads of federal offices from the sectors affected by climate change.

Responding and adapting to climate change requires that all affected sectors cooperate and collaborate, stressed Fetene Teshome, General Manager of the Ethiopian Meteorological Institute, in his opening remarks. Experts and regional and local representatives should come together to establish a system that can gather quality information and disseminate it to its users, he added.

“We can’t tackle climate change easily, so we have to find ways to live with it and use it to our benefit,” said Habtamu Itefa, minister of water and energy. He urged the workshop participants to approach the NFCS as a system designed to outlive governments and called them to play an essential role in its implementation in their respective regions, zones, districts and kebeles (sub-districts).

“Climate services will bring meaningful changes in agriculture”

Among the sectors most affected by climate change, agriculture accounts for about 40% of the GDP and employs more than 80% of the population, making it the backbone of the Ethiopian economy. It is thus crucial to address climate change impacts on the sector.

CIMMYT Senior Scientist, Kindie Tesfaye, explained how the AICCRA project works to enhance access to climate information services and validated climate-smart agriculture technologies in six African countries, including Ethiopia. As a stakeholder of the project, CIMMYT is training farmers, development agents, and local agricultural experts, and other agricultural value chain actors on the use of climate advisory services in collaboration with LERSHA, a digital platform providing farmers with contextualized weather forecast, inputs, mechanization and financial advisory services.

“We consider climate as a major problem for the country’s agricultural activities because the sector is heavily dependent on rain-fed production system and we believe that implementing this national framework on climate services will bring meaningful changes to the sector enabling it to manage climate risks successfully,” said Kindie Tesfaye.

The AICCRA project supported strengthening the function of the NFCS coordination team for multi- stakeholder engagement, supporting the endorsement of the framework and providing training on resource mobilization for its implementation. The project is also building capacity at different levels, promoting climate smart agriculture.

Productive in-depth discussions

Prior to the NFCS endorsement, participants shared inputs from their respective regions and sectors, providing inputs to the framework. Delegates mostly discussed capacity building needs, information delivery channels, synergetic cooperation among government institutions and mobilization of resources for implementation.

On the second day of the workshop, four different papers were presented on a seasonal climate update for the 2023 Bega season (October to December), on the impacts outlook for the upcoming Bega season, on the national state of the climate, and on climate risk management in agriculture extension.

The plenary discussion that followed was led by Fetene Teshome and offered an opportunity to the participants to raise their concerns on the implementation of the framework in their respective regional states. Many of the participants reflected on how the framework can accommodate the different ecology of various areas and how it can upgrade or replace dysfunctional meteorology infrastructures.

The Climate Risk Curriculum module that was prepared by AICCRA for agricultural extension workers was also launched during the workshop.

What is sustainable intensification?

Written by Mary Donovan on October 14, 2020. Posted in Explainers.

By 2050, the world’s population could grow to 9.7 billion, food demand is expected to increase by 50% and global demand for grains such as maize, rice and wheat could increase by 70%. How can we meet the food and nutrition demands of a rising population, without negative environmental and social consequences?

Sustainable intensification is an approach using innovations to increase productivity on existing agricultural land with positive environmental and social impacts. Both words, “sustainable” and “intensification,” carry equal weight.

CIMMYT conducts research on sustainable intensification to identify ways farmers can increase production of crops per unit of land, conserve or enhance important ecosystem services and improve resilience to shocks and stresses, especially those due to climate change and climate variability.

For example, CIMMYT’s research on sustainable intensification in India has helped shape policies that increase farmer income while reducing pollution and land degradation.

What is the scope of sustainable intensification?

Sustainable intensification takes into consideration impact on overall farm productivity, profitability, stability, production and market risks, resilience, as well as the interests and capacity of individual farmers to adopt innovations. It is not limited to environmental concerns, but also includes social and economic criteria such as improving livelihoods, equity and social capital.

Certain methods and principles are needed to achieve the goals of sustainable intensification. In collaboration with farmers and other change actors, CIMMYT carries out research-for-development projects to test and scale a range of technologies and approaches that contribute to these results. The research focuses on combined resource use efficiencies of crop production inputs: land, plant nutrients, labor and water.

One example is conservation agriculture, the combination of crop diversification, minimal soil movement and permanent soil cover. International scientific analysis has found that conservation agriculture can, in many places with different characteristics, play a crucial role towards achieving the United Nations Sustainable Development Goals.

Crop and system modeling, geographic information systems, remote sensing, scale-appropriate mechanization and socioeconomic modeling are some of the approaches that contribute to the design and evaluation of sustainable intensification alternatives in current farming systems.

What are some more examples?

Several interventions by CIMMYT aim at safeguarding biodiversity and protecting — in some cases increasing — ecosystem services crucial for small-scale farmers’ livelihoods and the health of all. Others have studied the impact of landscapes on dietary diversity and nutrition. Yet others have developed appropriate small-scale machines, allowing farmers to save time, costs and labor associated with agriculture to increase yields, halt the expansion of the agricultural frontier and invest in new opportunities.

How is sustainable intensification different from ecological intensification, agroecological intensification or climate-smart agriculture?

Sustainable intensification, ecological intensification and agroecological intensification strive for the same general goal to feed an increasing population without negative environmental and social consequences, but they place emphasis on different aspects.

Ecological intensification focuses on ecological processes in the agroecosystem. Agroecological intensification emphasizes a systems approach and strongly considers social and cultural perspectives.

Climate-smart agriculture and sustainable intensification are complementary, but climate-smart agriculture focuses on climate stress, adaptation and mitigation.

Sustainable intensification can be achieved with a range of methods, including these concepts. It is one strategy among many for global food system transformation.

What is the history of CIMMYT’s research on sustainable intensification?

In the 1960s, the Green Revolution brought high-yielding crops to some regions of Latin America and South Asia, allegedly saving millions from starvation. Yet the Green Revolution had unintended environmental and social consequences. Critics of the Green Revolution argued these cropping techniques were highly dependent on external inputs, fossil fuels and agrochemicals, causing environmental damage through overuse of fertilizers and water, and contributing to soil degradation.

In the 1980s, CIMMYT scientists began placing stronger emphasis on environmental and social aspects — such as conserving soil and water, and ensuring social inclusion of marginalized groups — recognizing their importance to sustain the intensification of crops in South Asia. It was understood that sustainability includes improving the livelihoods of rural people who depend on these natural resources, in addition to better resource management. CIMMYT began to take these considerations to the core of its work.

Are these practices successful?

Sustainable intensification can boost yields, increase farmers’ profits and reduce greenhouse gas emissions. The reduction of greenhouse gas emissions can be achieved by increasing nitrogen use efficiency, which also reduces groundwater pollution.

Research from CIMMYT’s SIMLESA project has shown that conservation agriculture-based sustainable intensification practices led to a 60-90% increase in water infiltration and a 10-50% increase in maize yields in Malawi. In Ethiopia, crop incomes nearly doubled with crop diversification, reduced tillage and improved varieties, compared to using only one of these practices.

According to research from Stanford University, agricultural intensification has avoided emissions of up to 161 gigatons of carbon from 1961 to 2005. CIMMYT research shows that India could cut nearly 18% of agricultural greenhouse gas emissions through sustainable intensification practices that reduce fertilizer consumption, improve water management and eliminate residue burning. Zero-tillage wheat can cut farm-related greenhouse gas emissions by more than 75% in India and is 10-20% more profitable on average than burning rice straw and sowing wheat using conventional tillage.

A CIMMYT study in Science shows that thousands of wheat farmers in northern India could increase their profits if they stop burning their rice straw residue and adopt no-till practices, which could also cut farm-related greenhouse gas emissions by as much as 78% and lower air pollution. This research and related work to promote no-till Happy Seeders led to a 2018 policy from the government of India to stop farmers from burning residue, including a $166 million subsidy to promote mechanization to manage crop residues within fields.

In light of this evidence, CIMMYT continues to work with stakeholders all along the value chain — from farmers to national agricultural research organizations and companies — to promote and scale the adoption of practices leading to sustainable intensification.

When mothers learn from babies

Written by Alison Doody on July 8, 2020. Posted in Blogs.

It was an early morning on March 12, 2020, when we entered Kiyasi Gwalale’s field in the Chebvute area of Masvingo, southern Zimbabwe. Gwalale participates in the Zambuko Livelihoods Initiative, funded by the United States Agency for International Development (USAID).

The Zambuko initiative aims to increase rural resilience against the negative effects of climate change. More than 70% of smallholders in Zimbabwe farm on sandy soils that are low in soil fertility and are increasingly affected by the vagaries of climate. The Gwalale family is an example of one of the millions affected.

In Chebvute, the International Maize and Wheat Improvement Center (CIMMYT) has established trials to test the effectiveness and productivity of conservation agriculture and climate resilient crop species since 2018. This has been in the form of “mother and baby” trials.

A traditional tool of breeders, “mother trials” show different technologies to farmers to allow them to select the best option. In Chebvute, these trials were amplified to demonstrate farmers’ crop management practices such as conservation agriculture, crop rotation with legumes and different drought-resilient crop varieties.

Baby trial farmers taking after their ‘mothers’

Since 2019, the best options have been taken on by follower farmers in so called “baby trials”, where they use a subset from the mother trials to gain first-hand experience with the technology. Learning by doing is a central concept of this approach.

Gwalale as a “baby trial farmer” learned from the mother trials that drought-tolerant maize varieties out-yield traditional varieties under conservation agriculture, but need to be rotated with legumes to also improve the soil and the nutrition of the farm household. In addition, she realized that planting white sorghum is a drought-resilient strategy in this area as small grains are less affected by in-season dry-spells.

Gwalale and her family have been resident in Chebvute for 15 years but farm only on 0.4 ha of land. With her husband and three children, she grows maize, sorghum, groundnuts and Bambara nuts. What she gets from these fields is barely enough to survive.

In the 2019/20 cropping season, a devastating drought lasting from mid-December to mid-January destroyed all her hopes that this year would be a better season. Instead, she went on an educational journey to find out how improved farming practices can make a difference in her own life.

“We planted this baby trial for the first time in December 2019, as we had seen from the nearby mother trials that these varieties planted under no-tillage seem to grow better than our own. We planted the baby at the same times as our own crops, but instead of tilling the soil and clearing the land, which we are used to, we just planted in riplines without tillage and covered the soil with mulch,” explains Gwalale.

“When the drought came, all my other crops in the tilled fields started to wilt and die — some did not even germinate. We could not believe what was happening in this baby trial”.

Resounding results in the baby trial

All crops in the baby trial survived the dry-spell and when the rains started to fall again in January, they continued to grow very well. Gwalale replanted the crops in the affected fields but they never caught up with the baby trial. Even after using the ripper to make more riplines, it was too late to experience the same wonder seen in the baby trial. “For now, we are yet to see how much we will get from this small field, but we learned a big lesson and want to expand our land area with this way of planting next year,” she says.

More than 200 baby trial farmers in Chebvute, the majority of which are women, have experienced the same in their own baby trials and realized that it does not take much effort to achieve food security.

Timely planting, conserving the soil and the moisture with conservation agriculture, effective weeding and application of adequate plant nutrients are the key ingredients of success. This can be learned effectively in a small plot such as a baby trial. Farmers have realized that it is possible to make a difference when they apply the principles of sustainable agriculture in their farming systems. The interventions introduced will help them to become more climate-resilient and ultimately more food secure.

Conservation agriculture feeds people and protects the environment

Written by Shiela Chikulo on June 4, 2020. Posted in Features.

On June 5, 2020, the world celebrates World Environment Day as COVID-19 continues to cause challenges and restrictions. Existing threats of climate change with the new challenges of a global pandemic adversely affect the agricultural sector, a mainstay of most sub-Saharan African economies. This situation calls for increased attention to how agriculture is practiced and natural resources — such as soil and water — are cared for.

Smallholder farmers in Zimbabwe are custodians of these natural resources, yet climate variability of shifting rainfall seasons, El Niño and droughts threaten successful rain-fed farming. Coupled with conventional farming practices such as tillage and deforestation, the soil structure and chemical quality are gradually degrading. Each passing year has resulted in declining yields, food insecurity and increased household vulnerabilities, particularly in drought-prone, low rainfall areas of southern Zimbabwe.

With support from the Swiss Agency for Development and Cooperation (SDC), the R4 Rural Resilience Initiative, led by the World Food Programme (WFP), aims to enable vulnerable, smallholder farmers to increase their food security, income and resilience by managing climate-related risks. Building on R4, WFP has just launched the Zambuko Livelihoods Initiative, focusing on social cohesion of communities, improved crop and livestock production and improved access to finance, with support from the United States Agency for International Development (USAID). The International Maize and Wheat Improvement Center (CIMMYT) is a partner to implement the project component on appropriate seeds and agricultural practices.

We discuss the R4 Rural Resilience Initiative with Christian Thierfelder, the Principal Cropping Systems Agronomist and a Strategic Leader for Africa at CIMMYT, and Munaye Makonnen, the Project Lead from WFP in Zimbabwe.

How is the R4 Rural Resilience Initiative responding to climate change challenges in the sites of intervention – Chebvute and Mwenezi?

Thierfelder: The R4 and Zambuko initiatives pursue an integrated approach to increase resilience of smallholder farming communities. Different partner organizations have come together in these projects to pursue different interventions such as building dams and vegetable gardens as community assets, financial education, promotion of improved climate-smart technologies such as drought-tolerant seed in combination with conservation agriculture, insurance, and linking farmers to markets. The combined actions address all needs and shortfalls in the target communities. We see a transformational change from mere subsistence farming to a more commercially oriented farming by targeted smallholders.

Makonnen: Recognizing the need to address livelihoods holistically, R4 offers farmers a set of integrated tools so that communities can better manage climate risks. Farmers participate in activities that enhance the natural resource base at watershed level, helping them adapt to climate change. They also benefit from a weather index insurance cover that protects them against drought and incentivizes them to engage in high-risk high-return investments. In the case of minor shocks, farmers have their savings groups to draw up on and can access small credit for income generating activities. With the aim of increasing productivity and income, conservation agriculture practices are promoted. For their surplus production, participants are also supported in accessing markets. The project also plans to include a component on climate services that will allow communities to mitigate the impacts of disaster risk, increase production and enhance adaptation to climate change.

Since inception, how have the farming communities responded to the technologies and practices introduced in their respective sites?

Thierfelder: Farming communities were very skeptical initially about this new approach. However, the varieties and cropping systems displayed in our 10 mother trials showed dramatically higher yields than farmers observed in their own fields, so it was not difficult to get 200 baby trial farmers to experiment with the technology. During the 2019/2020 cropping season, farmers got even more excited to see maize and legume yields thrive in their baby trials while crops planted under conventional agriculture failed. In the next cropping season, we hope to reach the tipping point of farmers trying and experimenting with these climate-smart agriculture technologies to achieve a transformational change towards more resilience.

Makonnen: Looking at the performance of the trials, farmers can see for themselves that the agricultural practices promoted by the project result in higher yields. They also get practical experience by trying these out on their own fields. Such an approach has worked well in terms of getting farmers to become interested in and eventually adopt conservation agriculture principles because it is not just based on theory — farmers can actually see and experience the change for themselves.

Even in times of COVID-19, the work must continue, observing social distancing and using facemasks. Christian Thierfelder outlines trials with farmers in Mwenezi, Zimbabwe.

In the wake of the COVID-19 pandemic and disturbance to agri-food systems, how is the R4 Rural Resilience Initiative addressing the emerging challenges?

Thierfelder: We have created the base of more resilient farming systems that should positively respond to all external shocks – droughts, floods and maybe a virus as well. In our technology package we do promote self-pollinating legumes such as cowpea and groundnuts which can be grown even when farmers are cut off from supply chains for seed and fertilizer. We therefore hope that this can be a contribution to reducing the negative impact of the COVID-19 crisis.

Makonnen: As COVID-19 is compromising food security, it is now more important than ever to ensure that agricultural production continues to function smoothly. R4 continues to provide all the services in its integrated risk management package despite the pandemic. As farmers face challenges in production, including limited access to labor, we hope that high yielding and less labor-intensive conservation agriculture practices promoted by R4 really come into their own. Ensuring the safety of our beneficiaries, staff and partners is a priority for WFP so we have developed guidelines for R4 implementation in the context of COVID-19. For instance, trainings are taking place in smaller groups, social distancing is observed in all activities, messages on COVID-19 prevention are shared with beneficiaries and we are also looking into digital solutions to continue implementation during these unprecedented times.

Looking ahead, how will the adoption of appropriate agricultural practices and seed varieties strengthen the resilience of the farming communities?

Thierfelder: Our approach has been multi-faceted addressing different areas of concern to the farmers: income generation, credit, improved productivity, insurance and marketing. We believe that with this mix of interventions farming can more effectively withstand external stresses. However, we also realize that adoption does not happen overnight and requires a significant experimentation and learning process with farmers. WFP has seen the need for longer term investments, and this is now beginning to pay off.

Makonnen: Adoption of appropriate agricultural practices and seeds is just one of the components of R4. We know resilience requires a holistic approach which is why we have a set of interventions within R4 involving multiple partners. R4 will continue to work across the entire value chain bringing together natural resource management, access to financial services, access to inputs and markets and promotion of appropriate agricultural practices so that the farmers we work with are well equipped to manage risks and become resilient to the changing climate and risks to their food security.

A wake-up call for the fertilizer industry

Written by Marta Millere on January 23, 2020. Posted in Features.

When you hear the words ‘plant nutrition’ or ‘fertilizer’, do you think of sustainability?

Many might not but the recent gathering of plant nutrition experts in Versailles at the High Level Forum on Sustainable Plant Nutrition might indicate that the tide is turning.

“This event is a first of its kind. Here you have the fertilizer industry, which is relatively conservative, and yet there are speakers such as Mostafa Terrab of the OCP Group or Svein Tore Holsether of Yara who are pushing this future agenda,” said Bruce Campbell, Director of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).

“If I was from the fertilizer industry, I would really wake up, as perhaps is happening with some companies. If you look at the airlines industry, you see some super visionary players and others who are not. I feel that there could be players in this group who could be as visionary: looking at cutting down the energy inputs into fertilizer production, working together with governments to reform subsidies that promote over-fertilization, working towards precision fertilizer application. If the fertilizer industry wants to gain the trust of a more and more discerning public, then they need to show climate leadership,” Campbell remarked.

The right time and place

Although fertilizer use revolutionized agriculture and allowed farmers to grow better crops on less land, plant nutrients are often vilified because of the negative environmental impact caused by their improper use.

For this reason, experts often speak of the 4R stewardship principles of fertilizer: right fertilizer source, at the right rate, at the right time, and in the right place.

“The industry needs solid science to back up agricultural technology solutions in the realms of both nutrient and water management. Regarding the right placement, right time and the right quantity of fertilizer, mechanization solutions — such as direct seeders, which place fertilizer close to the seed — can really increase nutrient use efficiency and improve plant early vigor. Together with a wide range of partners, CIMMYT has been using these across smallholder systems of Asia, Africa and Latin America,” highlighted Martin Kropff, Director General of the International Maize and Wheat Improvement Center (CIMMYT), during one of the panel discussions.

In order to scale up the most relevant scientific findings and extension efforts, the focus should be on using available fertilizers better. This goes hand in hand with better management of organic matter and soils. There is a human element too: farmers’ efficiency could be improved with better advice especially targeted at extension offices or service providers.

S for sustainability

In order to identify the missing link of sustainability, just a day before the launch of the forum, the International Fertilizer Association (IFA) created a new Scientific Panel on Responsible Plant Nutrition. This group of international experts will provide objective knowledge and assessments for the fertilizer industry and other stakeholders to develop a more responsible plant nutrition system.

Bruno Gérard, Director of CIMMYT’s Sustainable Intensification research program and a member of the panel, spoke about CIMMYT’s unique selling proposition. “CIMMYT has a significant research agenda and experience in better nutrient management in wheat- and maize-based systems. In regions such as South Asia, the challenge is to produce more or the same with less and better fertilizers through improved management practices. Instead in Sub-Saharan Africa, the focus is on giving better access and knowledge so that farmers can produce more with adequate fertilizer inputs.”

Being part of the panel will give CIMMYT the opportunity to better link up with the fertilizer industry and contribute to improved fertilizer use in term of profitability, yield stability and risk, accessibility but also — from an environmental perspective — minimize the footprint of fertilizer through better agronomic practices and management.

The High Level Forum on Plant Nutrition took place on November 18-20, 2019, in Versailles, France.

CIMMYT and CGIAR staff join Ethiopia’s record-breaking tree-planting campaign

Written by Rodrigo Ordóñez on August 1, 2019. Posted in News.

Staff members of CIMMYT and other CGIAR centers in Ethiopia participated in the country's nationwide campaign that resulted in the planting of more than 350 million trees in one single day.

July 29, 2019, was a remarkable day for Ethiopia. People across the country planted 353,633,660 tree seedlings in just 12 hours, according to the official count, in what is believed to be a world record. This figure also exceeded the target of a nationwide campaign calling citizens to plant 200 million trees in one day. This initiative was part of the Ethiopian government’s “Green Legacy” initiative, which aims to plant 4 billion trees by October.

The International Maize and Wheat Improvement Center (CIMMYT) and other CGIAR centers working in Ethiopia joined the tree-planting campaign. In the morning of July 29, staff members turned out at Adwa park, near Addis Ababa’s Bole International Airport, to plant tree seedlings. This activity was coordinated by the International Livestock Research Institute (ILRI) after receiving an invitation from the Bole subcity administration.

Ethiopia’s tree-planting day received worldwide attention. Al Jazeera reported that, “in addition to ordinary Ethiopians, various international organizations and the business community have joined the tree planting spree which aims to overtake India’s 66 million planting record set in 2017.”

A greener future for CGIAR

Ethiopia’s reforestation efforts align with CGIAR’s sustainability strategy.

In its current business plan, CGIAR has five global challenges including planetary boundaries. Food systems are driving the unsustainable use of the planet’s increasingly fragile ecosystem. A stable climate, water, land, forests and the biodiversity they contain are a precious, yet finite, natural resource. Food systems account for about one-third of greenhouse gas emissions and will be profoundly affected by its impacts. Agriculture is driving the loss of the world’s forests and productive land, with 5 million hectares of forests lost every year and a third of the world’s land already classified as degraded. Agriculture accounts for about 70% of water withdrawals globally, is a major cause of water stress in countries where more than 2 billion people live, and water pollution from agricultural systems poses a serious threat to the world’s water systems.

With Ethiopia’s increasing population, there is a high pressure on farmland, unsustainable use of natural resources and deforestation.

At the Agriculture Research for Development Knowledge Share Fair organized in Addis Ababa on May 15, 2019, CGIAR centers demonstrated how they are working together to improve agriculture production and environmental sustainability, tackling local challenges and generating global impact in partnership with other organizations, communities and governments.

At the fair’s opening ceremony, Seleshi Bekele, Ethiopia’s Minister of Water, Irrigation and Electricity, noted that the country has policies, institutional arrangements as well as human and financial resources to work towards sustainability. As a result, Ethiopia has made remarkable achievements towards meeting the Sustainable Development Goals with the continued support and contributions from partners like CGIAR.

MEXICO CITY (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) was invited to discuss the findings of the EAT-Lancet Commission report and its implications for Mexico, during a launch event hosted by Mexico’s Health Department on March 4, 2019.

The report, published earlier this year, aims to offer an in-depth scientific analysis of the world’s food production systems and their impact on the planet and human health. It proposes a “planetary health diet” that balances nutrition with sustainable food production.

“Our first objective was to develop healthy diets for the 10 billion people who will inhabit the planet in 2050”, said Juan Ángel Rivera Dommarco, Director General of Mexico’s Public Health Institute and member of the EAT-Lancet Commission. According to Dommarco, the healthy diet recommended for Mexico had to increase the intake of fruits, vegetables, legumes and whole grains to avert chronic diseases and combat malnutrition and obesity.

The report also makes several recommendations to reduce the environmental impact of food production, taking into account planetary boundaries. “The world needs to sustainably intensify food production and to produce basic foodstuffs of higher nutritional value”, said Fabrice DeClerck, EAT’s Science Director.

“If anybody is able to manage the complex systems that will sustainably yield the volume of nutritious food that the world needs, that’s the farmer”, said Bram Govaerts, Director of Innovative Business Strategies at CIMMYT. “In Mexico, more than 500 thousand farmers already innovate every day and grow maize, wheat and related crops under sustainable intensification practices that CIMMYT and Mexico’s Agriculture Department promote with MasAgro”.

Víctor Villalobos Arámbula, Mexico’s Secretary of Agriculture, said that the EAT-Lancet Commission report recommendations were very much in line with the strategic public policies that Mexico plans to implement in the coming years.

Experts analyze food systems at EAT-Lancet Commission report launch in Ethiopia

Written by on February 13, 2019. Posted in News.

Earlier this year, the EAT-Lancet Commission published a groundbreaking report linking healthy diets and sustainable food systems. It proposed scientific targets that meet both the Sustainable Development Goals (SDGs) and the Paris Agreement action plan to reduce carbon emissions. Since then, more than 20 launch events have been scheduled around the globe, including Addis Ababa, Ethiopia.

On February 7, the African Union hosted the EAT-Lancet Commission on healthy diets for sustainable food systems. Government officials, researchers and experts attended the “Food Systems Dialogue on Ethiopia” and developed a list of recommendations going forward. Some of these included at least 10 percent resource allocation to agriculture, the creation of functional and efficient internal markets for enhancing food distribution within the country, post-harvest loss reduction, and stronger collaboration between government and other stakeholders.

“The report has drawn the attention of policy makers, civil society and donors,” said Kindie Tesfaye Fantaye, a researcher and crop modeler at the International Maize and Wheat Improvement Center (CIMMYT). “The event was a good opportunity to create awareness on the chronic problems of stunting and malnutrition in Africa, and agriculture’s central role in contributing to effective solutions.”

Tesfaye Fantaye said CIMMYT’s work is well aligned with the report’s recommendations. In addition to research on sustainable intensification approaches that improve livelihoods while reducing the environmental footprint, CIMMYT explores ways to reduce postharvest losses and increase the nutritional quality of food through biofortification.

During a high-level side event, the commissioners indicated that the report is in-line with the different African Union policies and strategies, including the Malabo Declaration on Agriculture and Postharvest Losses, Agenda 2063 and Comprehensive Africa Agriculture Development Program (CAADP).

“The power of food is its connection. If we get it right, it brings us to a healthy people and a healthy planet,” said Gunhild Anker Stordalen, the founder and executive chair of EAT Foundation.

New report calls for urgent diet and food system changes to sustainably feed world

Written by Courtney Brantley on January 17, 2019. Posted in News.

A new report by more than 30 world-leading experts in health and environmental sustainability offers a roadmap for a global food system that provides a healthy, sustainable diet for the world’s 10 billion people by 2050.

The report, Food in the Anthropocene: the EAT-Lancet Commission on healthy diets from sustainable food systems, represents the first comprehensive review of what constitutes a healthy diet from a sustainable food system.

Published jointly by EAT, a global non-profit foundation founded to catalyze a food system transformation, and The Lancet, the world’s leading medical journal, the report links diets with human health and environmental sustainability. It lays out five global scientific strategies to achieve healthy diets and sustainable food production by the year 2050: shifting diets, producing healthy food, sustainably intensifying food production, improving land and water governance, and reducing food loss and waste.

The report urges substantial dietary shifts and specific courses of action from consumers, policymakers, businesses and government agencies alike to transform the world’s food system. As the report states, “Without action, the world risks failing to meet the UN Sustainable Development Goals (SDGs) and the Paris Agreement, and today’s children will inherit a planet that has been severely degraded and where much of the population will increasingly suffer from malnutrition and preventable disease.”

The report emphasizes eating diets heavy in fruits, nuts, vegetables and whole grains and light on meat, as current Western-style diets are already straining the global food system’s environmental impact and pushing planetary limits. According to CIMMYT consultant and leading nutritionist Julie Miller Jones of St. Catherine University, USA, eating whole grain foods reduces obesity and the risk of almost all chronic diseases.

Given that the food system drives nearly 30 percent of greenhouse gas emissions, occupies 40 percent of land and causes 80 percent of biodiversity loss, increasing healthy, resource-saving foods and reducing unhealthy and unsustainably produced foods is an essential step in securing future environmental sustainability.

The founder and executive chair of EAT, Gunhild Stordalen, commented at the report’s launch event January 17 in Olso, Norway: “No single sector, technology or entity can fix it alone but, for the first time, we have a clear direction and initial targets to align and guide our actions.”

Precision levelers are climate-smart machines equipped with laser-guided drag buckets to level fields so water flows evenly into soil, rather than running off or collecting in uneven land. This allows much more efficient water use and saves energy through reduced irrigation pumping, compared to traditional land leveling which uses animal-powered scrapers and boards or tractors. It also facilitates uniformity in seed placement and reduces the loss of fertilizer from runoff, raising yields. (Photo: CIMMYT)

Agriculture can help the world meet climate change emission targets

Written by on December 11, 2015. Posted in Director General's corner.

As world leaders meet in Paris this week to agree on greenhouse gas emission targets, we in the field of agricultural research have a powerful contribution to make, by producing both robust estimates of the possible effects of climate change on food security, and realistic assessments of the options available or that could be developed to reduce agriculture’s contribution to greenhouse gas emissions.

Agriculture is estimated to be responsible for about a fifth of global greenhouse gas emissions, and this share is increasing most rapidly in many developing countries; it may even increase as fossil fuels become scarcer and phased out in other sectors.

The solution being put forward today is climate-smart agriculture (CSA), which involves three components: adaptation, mitigation, and increased productivity. Adaptation is essential to cope with the impacts that cannot be avoided and to maintain and increase the global food supply in the face of resource constraints; mitigation can lessen but not prevent future climate changes.

Though CSA has been held up as an answer to the challenges presented by climate change, some would argue that it is no more than a set of agricultural best practices. Indeed, this is what lies at the heart of the approach.

In addition to making agriculture more efficient and resilient, the overall purpose remains to sustainably increase farm productivity and profitability for farmers. This is why over the last few years we have begun talking about the ‘triple win’ of CSA: enhanced food security, adaptation, and mitigation. But those who dismiss CSA as mere best practice ignore the value of seeing through the climate change lens, and guiding research to respond to expected future challenges.

To begin with, crop performance simulation and modeling, in combination with experimentation, has an important role to play in developing CSA strategies for future climates.

In a publication titled “Adapting maize production to climate change in sub-Saharan Africa,” several CIMMYT scientists concluded that temperatures in sub-Saharan Africa will likely rise by 2.1°C by 2050 based on 19 climate change projections. This is anticipated to have an extreme impact for farmers in many environments. Because it takes a long time to develop and then deploy adaptation strategies on a large scale, they warned, there can be no delay in our work.

This explains why CIMMYT is taking the initiative in this area, seeking support to develop advanced international breeding platforms to address the difficulty of developing drought-tolerant wheat, or bringing massive quantities of drought- and heat-tolerant maize to farmers through private sector partners in Africa and Asia.

Our insights into the causes and impacts of climate change lead us to important research questions. For example, how can farmers adopt practices that reduce the greenhouse gas footprint of agriculture while improving yield and resilience?

Colleagues at CIMMYT have challenged the idea that the practice of no-till agriculture (which does not disturb the soil and allows organic matter to accumulate) contributes significantly to carbon sequestration. I think it is important that we, as scientists, explore the truth and be realistic about where opportunities for mitigation in agriculture lie, despite our desire to present major solutions. It is also important to take action where we can have the greatest impact, for example by improving the efficiency of nitrogen fertilizer use.

Nitrous oxide emissions from agriculture have a climate change potential almost 300 times greater than carbon dioxide, and account for about 7% of the total greenhouse gas emissions of China. Improved nutrient management could reduce agricultural greenhouse gas emissions by the equivalent of 325 Mt of carbon dioxide in 2030. Overall, supply-side efficiency measures could reduce total agricultural emissions by 30%.

Some practices, such as laser land leveling, fall into both the adaptation and mitigation categories. Preparing the land in this way increases yields while reducing irrigation costs, the amount of water used, nutrients leached into the environment, and emissions from diesel-powered irrigation pumps.

Findings such as this offer real hope of reducing the severity of climate change in the future, and help us build a case for more investment in critical areas of agricultural research.

For climate-smart agriculture, the challenge of feeding more people and reducing emissions and environmental impact is not a contradiction but a synergy. We are improving our ability to predict the challenges of climate change, and proving that it is possible to greatly reduce agricultural emissions and contribute to global emission goals.

To face challenges such as climate change, we need high quality multi-disciplinary science combined with approaches to address problems at the complex systems level. Since my involvement in early large-scale studies, such as Modeling the Impact of Climate Change on Rice Production in Asia (CABI/IRRI, 1993), I am pleased to see that so much progress has been made in this regard and encouraged that our research is contributing to greater awareness of this vital issue and solutions to address it.
