The negative impacts of climate shocks have undermined the food security of millions of people in Ethiopia, where predominantly rain-fed agriculture and cereals comprise 82% of the crop area and are particularly susceptible to extreme climate events like drought or flooding. Predictions that can account for potential climate events can facilitate efforts of governmental agencies to proactively engage in climate mitigation efforts.

Led by the International Center for Maize and Wheat Improvement (CIMMYT), the Accelerating Impact of CGIAR Climate Research for Africa (AICCRA) project conducted a five-day training workshop in Adama, Ethiopia for 12 data experts from 23-27 December 2021 on the CCAFS Regional Agricultural Forecasting Toolbox (CRAFT) Tool.

The five-day training workshop exposed select national experts involved in data collection and analysis of crop performance to the CRAFT tool, which is expected to improve accuracy, efficiency, and speed of forecasts.

The participants of the training were experts from the Ministry of Agriculture (MoA), National Meteorology Agency (NMA), and Ethiopian Disaster Risk Management Commission (EDRMC).

CRAFT has been developed in collaboration with CIMMYT, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), and the University of Florida through the Capacitating African Smallholders with Climate Advisories and Insurance Development (CASCAID-II) program. CRAFT is a flexible and adaptable software platform, relying on a crop engine to run pre-installed crop models and on the Climate Predictability Tool (CPT) to utilize seasonal climate predictions to produce crop yield forecasts. The tool has been calibrated, evaluated, and tested under Ethiopian ecological conditions.

In the opening of the training workshop, Esayas Lemma, Director of the Crop Development Directorate at the MoA, emphasized institutions must be equipped with the necessary analytical and decision support tools to enable decision makers to make critical decisions at the right time due to increasing challenges to food security. He added the training organized by CIMMYT through the AICCRA-Ethiopia project was timely and important for enhancing the capacity of the experts drawn from the three institutions and building national capacity in using modern decision support tools.

Kindie Tesfaye, senior scientist at CIMMYT, stated the training was organized to help experts in national institutions in applying decision support tools to equip decision makers with information to help them minimize costs, save lives, and enhance long-term climate risk management and policy options in Ethiopia. “We hope to bring this technology to other countries following this roll-out in Ethiopia,” Tesfaye said.

“The training is an eye-opener for me, and this is the type of tool that we have been looking for,” said Mss. Berktawit, a trainee from EDRMC.

“The CRAFT tool has several applications in the MoA, and we are lucky to have this training. With some additional training, we at the ministry should be able to use it to support our crop monitoring and early warning works,” said Mr. Zewdu, a trainee from the MoA.

A follow up training session will be organized to certify participants as they continue working with CRAFT. “Feedback from these users will be vital to optimize inputs for CRAFT and to develop an intuitive user interface,” Tesfaye said.

CGIAR Initiative: Securing the Food Systems of Asian Mega-Deltas (AMD) for Climate and Livelihood Resilience

Securing the Food Systems of Asian Mega-Deltas (AMD) for Climate and Livelihood Resilience aims to create resilient, inclusive and productive deltas — which maintain socio-ecological integrity, adapt to climatic and other stressors, and support human prosperity and wellbeing — by removing systemic barriers to the scaling of transformative technologies and practices at community, national and regional levels.

This objective will be achieved through:

  • Adapting deltaic production systems by identifying, synthesizing, evaluating, adapting and scaling interventions to ensure systems can adapt to and mitigate the effects of salinity, flooding, drought, terminal heat and sinking land.
  • Nutrition-sensitive deltaic agrifood systems, developed through the promotion of sustainable production and consumption of nutritious foods in Asian mega-deltas, by involving institutional stakeholders in the co-production of nutrition-sensitive interventions.
  • De-risking delta-oriented value chains by assessing the potential of digital climate advisory and complementing services to address climate risks among vulnerable groups, supporting development of improved and inclusive digital and bundled services, and identifying and developing financing models and partnerships to achieve scale.
  • Joined-up, gender equitable, inclusive deltaic systems governance, informed by transdisciplinary research evidence, local knowledge and political economy insights used to coordinate multi-stakeholder dialogues for more coherent water-agriculture-environment policies and strategies; collaborative, networked implementation practices; and gender-equitable and socially inclusive governance innovations.
  • Evidence-based delta development planning at the macro-level to ensure plans/policies incorporate inclusive and climate-proof approaches to food systems transformation.

CGIAR Initiative: Transforming Agrifood Systems in South Asia (TAFSSA)

Working across South Asia, the Transforming Agrifood Systems in South Asia (TAFSSA) Initiative will deliver a coordinated program of research and engagement across the food production to consumption continuum to improve equitable access to sustainable healthy diets, improve farmer livelihoods and resilience, and conserve land, air, and groundwater resources.

TAFSSA aims to propel evidence into impact through engagement with public and private partners across the production-to-consumption continuum, to achieve productive, environmentally-sound South Asian agrifood systems that support equitable access to sustainable healthy diets.

This objective will be achieved through:

  • Facilitating agrifood systems transformation through inclusive learning platforms, public data systems and partnerships: building new and enhancing existing learning platforms; improving the evidence base; increasing quality data availability and accessibility; and demonstrating the value of integrated agrifood systems datasets.
  • Transforming agroecosystems and rural economies to boost income, generate jobs and support diversified food production within environmental boundaries: generating linkages between farmers, landscapes and markets to diversify agricultural production, increase farmers’ incomes and foster rural entrepreneurship within environmental boundaries.
  • Improving access to and affordability of sustainably produced healthy foods through evidence and actions across the food system: creating favorable environments for diversification; improving access to inputs for and marketability of sustainable nutritious food; and improving access to healthy food for the poor through changes in food retail environments.
  • Understanding behavioral and structural determinants of sustainable healthy diets: studying dietary practices of food consumers; identifying determinants of food choices; and testing innovations to support consumption of sustainable healthy diets.
  • Building resilience and mitigating environmental impact: examining how South Asia can produce healthy diets within an environmentally safe and socially equitable operating space, and in consideration of ongoing climate change and farmers’ resilience to shocks.

In Ethiopia, local challenges inform national action for climate-smart agriculture

In some of Ethiopia’s most vulnerable communities, climate change is having a disastrous effect on agriculture, a critical sector to the livelihood of millions. Droughts, floods, pests, and disease outbreaks are key challenges farmers face in the age of the climate crisis. These climate-related threats have already contributed to reducing agricultural productivity and food insecurity.

In order to minimize agricultural risks from the above challenges and maximize farmers’ resilience, there is a critical need to introduce the technologies, innovations, and practices that underpin ‘climate-smart agriculture. For instance, cascading knowledge on agricultural risk management and promoting conservation agriculture may prove to be sustainable practices that address the limiting factors of food security. This, however, cannot be done in a ‘one-size-fits-all’ approach. In Ethiopia, we’ve seen how climate-smart agriculture (CSA) not only needs to be localized – so it is effective in different environments – it also needs to be inclusive, meeting the needs of women and youth in various communities.

CSA is critical to making Ethiopian farmers and their communities more resilient in the face of climate change. Awareness-raising campaigns and consultations fit an important role in engaging scientists, practitioners, and beneficiaries to understand and implement area-specific climate adaptation mechanisms through CSA-based input. A current challenge is that climate-smart interventions in Ethiopia are limited because of a lack of awareness of the necessary skill set to implement and manage those technologies properly. After all, it is wise to remember that CSA is a knowledge-intensive exercise. For instance, let us look at the Ethiopian highlands, which constitute a substantial amount of the country’s farming population. In the extreme highlands of Ethiopia – generally dubbed as Wurch or mountain zone above 3800m elevation above sea level – CSA implementation is even scarce due to climatic and socio-economic conditions. In fact, those parts of the highlands are often referred to as the “forgotten agroecology” and agricultural research institutions – both in Ethiopia and beyond – must develop and package climate-smart interventions tailored for regions that have these agroecological characteristics.

Despite some practical challenges, it is also wise to note that there are successful cases of CSA implementation and addition across the various parts of the country. This is recognized for the literature review to document CSA experiences in the country and develop a detailed ‘CSA compendium’. These experiences can promote public engagement informed and inspired by the practical experience of climate-smart interventions, both from sites that have similar agroecological characteristics – as well as different – so that farmers and communities can learn from the successes and failures of other ventures. This public engagement should be underpinned by business and financing models that work for resource-poor farmers, so they can access or invest in making their agriculture more climate-smart.

Knowing what works where will be essential to develop strategies that can facilitate targeting and scaling CSA approaches. Developing a CSA compendium, a collection of concise but detailed information on CSA practices can be an entry point to achieve this – which also requires efforts from various experts and collaboration among institutions in the country and beyond.

In line with this understanding, a recent workshop in Ethiopia brought together researchers from the Ethiopia Institute of Agricultural Research (EIAR) and the Ministry of Agriculture, the Regional Bureau of Agriculture, alongside partners from regional agricultural research institutes, Universities, and CGIAR centers.

It aimed to raise awareness among partners on the kinds of climate-smart packages of agricultural technologies and practices that are socially inclusive and responsive to the needs of young people while also being feasible from a socio-economic standpoint and ready to be expanded and delivered on a bigger scale. Key presentations were made about what CSA is and what it is not. In addition, the type and description of indicators used to identify CSA practices that are economically feasible, socially acceptable, and gender-responsive were discussed in-depth. As part of this exercise, experts identified more than 20 potential climate-smart agriculture interventions tested, validated, and implemented effectively in different parts of the country.

Some of the key presentations and discussions at the workshop revealed critical lessons for implementing CSA:

  • Climate-smart agriculture is not a set of practices that can be universally applied but rather an approach that involves different elements embedded in local contexts.
  • Climate-smart agriculture relates to actions both on farms and beyond the farm, incorporating technologies, policies, institutions, and investment.”
  • Climate-smart agriculture is also a continuous process, though we should focus on the big picture and avoid trivial debates about whether CSA is a practice, technology, or an option.
  • Due consideration should be given to gender sensitiveness and social inclusiveness as a criterion in identifying compelling innovations.
  • Better indicators should be developed in measuring how climate-smart agriculture is adopted.

The workshop was the first of a series planned to raise awareness of different approaches to climate-smart agriculture while aligning Ethiopian institutions behind common understandings of how climate-smart agriculture can be delivered at both a local and national level.

In closing this first workshop, Ermias Abate, Deputy Director-General of the Amhara Region Agricultural Research Institute, stated, “Agriculture wouldn’t move an inch forward if we continued with business as usual and hence the need to be smart to face the new realities of agriculture under climate change.”

The Accelerating Impacts of CGIAR Climate Research in Africa (AICCRA) workshop was held between December 24 and 25, 2021, in Bahir Dar, Ethiopia, and was organized jointly by:

  • The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT)
  • CGIAR Program on Climate Change Agriculture and Food Security (CCAFS)
  • International Maize and Wheat Improvement Center (CIMMYT)
  • International Center for Agricultural Research in the Dry Areas (ICARDA) and
  • International Livestock Research Institute (ILRI)

Biological nitrogen fixation and prospects for ecological intensification in cereal-based cropping systems

Among the inputs needed for a healthy soil, nitrogen is unique because it originates from the atmosphere. How it moves from the air to the ground is governed in part by a process called biological nitrogen fixation (BNF), which is catalyzed by specific types of bacteria.

Nitrogen supply is frequently the second most limiting factor after water availability constraining crop growth and so there is great farmer demand for accessible sources of nitrogen, such as synthetic nitrogen in fertilizer. This increasing demand has continued as new cereal varieties with higher genetic yield potential are being released in efforts to feed the world’s growing population.

Currently, the primary source for nitrogen is synthetic, delivered through fertilizers. Synthetic nitrogen revolutionized cereal crop (e.g., wheat, maize, and rice) production by enhancing growth and grain yield as it eliminated the need to specifically allocate land for soil fertility rejuvenation during crop rotation. However, synthetic nitrogen is not very efficient, often causing excess application, which leads to deleterious forms, including ammonia, nitrate, and nitrogen oxides escaping into the surrounding ecosystem, resulting in a myriad of negative impacts on the environment and human health. Nitrogen loss from fertilizer is responsible for a nearly 20% increase in atmospheric nitrous oxide since the industrial revolution. Notably, more nitrogen from human activities, including agriculture, has been released to the environment than carbon dioxide during recent decades, leading climate scientists to consider the possibility that nitrogen might replace carbon as a prime driver of climate change.

New research co-authored by International Maize and Wheat Improvement Center (CIMMYT) scientists, published in Field Crops Research, posits that facilitating natural methods of gathering useable nitrogen in BNF can reduce the amount of synthetic nitrogen being used in global agriculture.

As agricultural systems become more intensive regarding inputs and outputs, synthetic nitrogen has become increasingly crucial, but there are still extensive areas in the world that cannot achieve food and nutrition security because of a lack of nitrogen.

“This, together with increasing and changing dietary demands, shows that the future demand for nitrogen will substantially grow to meet the anticipated population of 9.7 billion people by the middle of the century,” said J.K. Ladha, adjunct professor in the Department of Plant Sciences at University of California, Davis, and lead author of the study.

Before the synthetic nitrogen, the primary source of agricultural nitrogen was gathered through BNF as bacteria living underground that convert atmospheric nitrogen into nitrogen that can be utilized by crops. Therefore, legumes are often employed as a cover crop in rotating fields to replenish nitrogen stocks; their root systems are hospitable for these nitrogen producing bacteria to thrive.

“There are ways in which BNF could be a core component of efforts to build more sustainable and regenerative agroecosystems to meet nitrogen demand with lower environmental footprints,” said Timothy Krupnik, Senior System Agronomist at CIMMYT in Dhaka, Bangladesh.

Plant scientists have often hypothesized that the ultimate solution for solving the ever-growing nitrogen supply challenge is to confer cereals like wheat, maize, rice, with their own capacity for BNF. Recent breakthroughs in the genomics of BNF, as well as improvements in the understanding how legumes and nitrogen bacteria interact, have opened new avenues to tackle this problem much more systematically.

“Enabling cereal crops to capture their own nitrogen is a long-standing goal of plant biologists and is referred to as the holy grail of BNF research,” said P.M. Reddy, Senior Fellow at The Energy Research Institute, New Delhi. “The theory is that if cereal crops can assemble their own BNF system, the crop’s internal nitrogen supply and demand can be tightly regulated and synchronized.”

The study examined four methods currently being employed to establish systems within cereal crops to capture and use their own nitrogen, each with their advantages and limitations. One promising method involves identifying critical plant genes that perceive and transmit nitrogen-inducing signals in legumes. Integrating these signal genes into cereal crops might allow them to construct their own systems for BNF.

“Our research highlights how BNF will need to be a core component of efforts to build more sustainable agroecosystems,” said Mark Peoples, Honorary Fellow at The Commonwealth Scientific and Industrial Research Organisation (CSIRO), Canberra, Australia. “To be both productive and sustainable, future cereal cropping systems will need to better incorporate and leverage natural processes like BNF to mitigate the corrosive environmental effects of excess nitrogen leaking into our ecosystems.”

Besides the efforts to bring BNF to cereals, there are basic agronomic management tools that can shift focus from synthetic to BNF nitrogen.

“Encouraging more frequent use of legumes in crop rotation will increase diversification and the flow of key ecosystem services, and would also assist the long-term sustainability of cereal-based farming systems­,” said Krupnik.

Mexican farming can transition to be more resilient with technology

In Mexico and around much of the world, the cost of food fell sharply last month but it remains dangerously close to the all-time highs posted earlier this year, according to an agency of the United Nations.

New data from the Food Price Index of the Food and Agricultural Organization provide even more proof that if we’re to build a resilient system of agriculture that keeps food abundant and affordable, farmers like me need access to the best, forward-facing and science-based technologies—and not the backward-looking restrictive measures that many governments are trying to force upon food producers.

That’s especially true here in Mexico, where public officials are promoting dangerous agriculture policies that will damage yield potential of Mexico’s farmers and add to our country’s current food inflation. Paradoxically, the world’s leading agricultural research center for wheat and maize has issued a new call for “long-term agri-food system resilience.”

The International Wheat and Maize Improvement Center, also known as CIMMYT and headquartered just outside Mexico City, is an amazing resource for farmers everywhere. My family has participated in its work for decades, going back to when Norman Borlaug, the father of the Green Revolution, was starting to make big progress on wheat yields.

In July, a team of CIMMYT scientists published their strategy for dealing with soaring food prices. They focused mainly on wheat, which was subjected to so much stress because of the Russian invasion of Ukraine, but their general recommendations apply to every commodity.

Their short-term advice involves boosting production and partially replacing wheat flour with other low-cost cereals to off-set high wheat prices. In the middle and long terms, CIMMYT calls for more resilience in our food systems by genetically improving seeds and controlling pests. Significantly, the authors urge “building capacity to promote extensive pest and pathogen monitoring.”

This is important advice because pests, weeds, and disease are three of the biggest threats to food production pretty much everywhere. If we’re going to develop a “long-term agri-food system resilience” that involves everything from the climate-change mitigation and gender equity that CIMMYT also advocates, it must start by helping farmers like me defend our crops from their most basic but permanently evolving threats.

And that means giving us access to science-based technology. We need the best seeds, the best machines, and the best crop management techniques. We also need the best crop protection so that what we plant can meet its full potential.

Rather than limiting the options of farmers we should seek to expand them. This in fact is the great legacy of CIMMYT. Through sound science and creative innovation, it has given farmers more tools than ever before.

On my farm, we already fight pests, weeds, and disease through traditional practices like crop rotation. Yet this age-old practice is no longer enough. In this era of sustainability and conservation, we especially need advanced crop protection, which can function as a “virtual plow” that strengthens our soil as it locks in moisture, kidnaps carbon, enhances biodiversity, improves root systems, and reduces erosion.

In the years ahead, we’d like to explore additional crop-protection technologies, such as drone applications which would allow us to work with more precision and less dependence on fossil fuels.

As we think about the future, and as farmers everywhere try to grow more food on less land, we should embrace technology as a solution rather than fear it as a problem.

We have so many real problems with war, inflation, access to fuel and fertilizer, market turmoil, and climate change that we don’t need to restrict ourselves by hesitating in the application of new technologies, especially when they have been demonstrated to be safe. (If we trick ourselves into banning these options, farmers will pay a steep price as they struggle to grow food and consumers will bear the cost of it whenever they eat.)  All technological options should remain on the table.

Although food prices fell by 8.6 percent between June and July, they are more than 13 percent higher than they were at this time last year, according to the FAO’s Food Price Index.

This may be a silver lining amid dark clouds, but the forecast is unpredictable: “The decline in food commodity prices from very high levels is welcome,” said FAO chief economist Maximo Torero, who also warned that “many uncertainties remain” and they “pose serious strains for global food security.”

Agriculture must become more resilient, as CIMMYT pleads.

And farmers like me need the support of policy makers and the general public as we struggle to grow the food everyone needs.
