CIMMYT’s work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.

The world must act to avert a climate-induced food shortage, cautions Cary Fowler. CIMMYT has a strategy to strengthen agrifood systems.

Erratic climate patterns, global and regional conflicts, biodiversity degradation, and insufficient funding for agricultural research pose a serious risk to meeting global food production goals by mid-century, according to Cary Fowler, the U.S. special envoy for food security.  

The world must produce 50-60% more food by 2050 to nourish a growing population. Yet global crop yields are projected to drop between 3-12% over the same period. Wheat yields in Africa and South Asia, two regions with the fastest growing and youngest populations, are expected to decline by 15% due to global warming. Food systems have also been disrupted by the Russia-Ukraine conflict and the COVID-19 pandemic, raising food and fertilizer prices, and exacerbating regional instability.

Fowler cites inadequate government funding for plant breeding programs as a contributor to an ineffective response to introducing improved climate-adaptable staple crops. “With the state of current affairs, we are on our way to failing to feed the world by century’s end,” said Fowler.  

Science and Innovation for a Food and Nutrition Secure World: CIMMYT’s 2030 Strategy 

Global peace and development efforts will demand a cross-sector and coordinated response. Through its 2030 Strategy, CIMMYT has laid out a robust series of investments in crop systems innovation, partnership, and sustainable development, to advance more resilient food systems. The 2030 Strategy consolidates CIMMYT’s target areas through three pillars: Discovery, SystemDev, and Inc. These pillars focus on research and innovation, systems approach, and strong partnerships and advocacy efforts with the private and government sectors to address an emerging food crisis. 

“Our 2030 Strategy places research, innovation and partnership at the center of facing the challenges of the 21st century to solve tomorrow’s problems today—for greater food security and the prosperity of smallholder farmers. As we implement work plans, CIMMYT is proud of the achievements it has seen through projects in sub-Saharan Africa, our contribution to influential policy reports, and continued praise for our agri-development initiatives in Latin America. All these feats will help us deliver on and expand our efforts to reach our 2030 vision,” said Bram Govaerts, CIMMYT director general.  

CIMMYT remains prominent in developing sustainable solutions for farmers and policy actors  

CIMMYT has achieved important progress in Eastern and Southern Africa. Projects such as the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub have brought together regional seed partners, government agencies, and CGIAR Research Centers, to reduce fertilizer prices, boost resilience to drought and pests, and facilitate market access for smallholders.  

In the recent SPG Coalition report, CIMMYT featured prominently as a leading organization in climate-smart agriculture, nutrient-use efficiency, and pest and fertilizer management. This report informs researchers, non-governmental organizations and private sector partners in agrifood and climate policy development.

MasAgro, a research-for-development initiative, has received praise by international organizations and governments as an exemplary program for sustainable development in Latin America. Over 500,000 farmers in Mexico have adopted hardy maize or wheat varieties and resource-conserving agricultural practices. To maximize on the experience of MasAgro, CIMMYT has partnered with a CGIAR initiative: AgriLAC Resiliente. This initiative aims to bolster the competitiveness and sustainability of agrifood systems to respond to forced migrations in Central and South America which are worsened by regional food insecurity and conflict.  

Science and innovation powered by partnership can deliver a food secure world  

Climate change undoubtedly threatens global peace and agrifood systems. With over 130 countries depending on food imports, today’s hyper-connected world demands collaborative partnership across all sectors to build up shockproof food systems. Through a grassroots approach to research and innovation, the CIMMYT 2030 Strategy is built upon decades of applied science which has impacted communities around the world, to continue influencing policy, pioneering innovations, and advocating for the development of a food secure future.  

Feed the Future Mechanization and Extension Activity

Written by mcallejas on . Posted in Uncategorized.

In 2015, the General Assembly of the African Union committed to retiring the hand hoe to museums and pushing for sustainable agricultural mechanization on the African continent.

Today, approximately 75-82% of smallholder farmers in eastern and southern Africa rely on human or animal draft power for primary tillage operations. Mechanization helps to reduce drudgery, increases productivity, and contributes to food security and increased livelihoods.

What is Feed the Future Mechanization and Extension Activity?

The Feed the Future Mechanization and Extension Activity, funded by the United States Agency for International Development (USAID), aims to improve smallholder farmers’ access to farm power and machinery to enhance their land and labor productivity.

This is achieved through three integrated components that stimulate demand for scale-appropriate machinery.

Components:

  1.  Identification of demand-driven smallholder farm machinery and building capacity of manufacturing companies to produce, repair, and import machinery for smallholder agricultural production systems.
  2. Building the capacity of local service providers to purchase, operate, and maintain farm machinery to provide mechanized services to small-scale agricultural value chain actors.
  3. Coordinate and collaborate with other FTF activities to build the capacity of interested local service providers.

What are the objectives?

  • Assess and build the capacity of smallholder machinery manufacturers and suppliers to manufacture demand-driven farm machinery.
  • Enhance land and labor productivity and income through the establishment of mechanization service provision to small scale agricultural value chain actors.
  • Promote the use of the machinery through demonstrations and other demand creation activities, and inclusive training of rural women and youth in post-harvest processing of agricultural produce to generate increased income.
  • Coordinate and collaborate with other mechanization and Feed the Future activities to build capacity of the interested service providers to be agricultural extension agents to their customers during the cropping season.
  • Support service providers, manufacturers, and distributors to access credit to acquire machinery or mechanized services.

The project sites are located in Zimbabwe’s Manicaland and Masvingo provinces with project presence implemented across 10 districts.

The Mechanization and Extension Activity will directly benefit 150 service providers who in turn will reach up to 22,500 women and men smallholder farmers through provision of mechanized services. In addition, the mechanization activity will identify and build the capacity of 30 rural mechanics and 30 technicians drawn from local farm machinery manufacturing companies and/or small and medium enterprises.

Show that you can thrive and excel in all environments

Written by Julian Bañuelos-Uribe on . Posted in News.

On August 29, CIMMYT held the latest installment of its seminar series on women’s leadership—Catalysts of Change: Women Leaders in Science. The online event featured a presentation from Lindiwe Majele Sibanda, an animal scientist by training, who has previously worked as policy advisor for numerous African governments and global institutions and currently serves as chair of the CGIAR System Board.

In her opening talk, Sibanda outlined the many and varied roles she has held throughout her career, including professor, farmer, and business owner. Discussing her early education in a segregated colonial Zimbabwe (then Rhodesia), her time as an undergraduate student in Egypt, or the challenge of starting a family alongside developing her career, Sibanda was keen to highlight the lessons learned at each stage of life and emphasized the importance of creating cross-cultural friendships, nurturing professional networks, establishing priorities, and promoting continuous learning.

A learning spirit

Sibanda has over 15 years of experience working as a governor at national, regional, and international levels, but it took some time to initially build her confidence in the role. She recalled feeling daunted during her very first meetings because she had not been trained, but her learning spirit helped carry her through. “I always looked around the room and chose my mentors—based on something I liked about their values—something I liked about the way they asked questions, or something I liked about their demeanor and how they engaged with others—and I started learning.”

This approach has garnered her a large circle of mentors—and friends—and having served on more than 12 different boards she now feels this is a space that she enjoys, particularly as there are still opportunities for learning. “I think it’s the spirit of continuous thirst for knowledge, for new information, that has kept me going.”

“And it’s all about integrity,” she added. “What people see in me is what they get. I’ve never had to be fake. What I know, I make sure I know very well. What I don’t know, I’m not shy to say I don’t know.”

Convince each other that it can be done

Having unpacked her life as a scholar, mother, working professional, and governor, Sibanda explained that her current focus is on giving back. For her, supporting the next generation of women in the workplace is a key part of leadership. She cited Graça Machel and Mama Mary Robinson as inspirations, both for their work ethic and their ability to connect with people at different levels. “But most importantly, they give it to other women,” she said. “They love mentoring girls and other women.”

In her own experience, some of the major obstacles she faces as a woman, a farmer, and an African are the specific biases associated with each of those three things. “Women need to be helped, they are disadvantaged; farmers are poor, especially if they come from Africa; and mothers need to spend more time at home and not be globetrotting to meetings.” To counter these biases, she explained, it is important to show that you can thrive and excel in all environments. “It’s not about either or, it’s about showing we can do it, regardless of the circumstances.”

“Women are natural agents of change, and all they need is a conducive environment. As women, we should be spending more time with other women, making sure we share our stories, our successes, and our struggles. The whole idea is to convince each other that it can be done.”

Sibanda’s presentation was followed by a Q&A session led by Ana Luisa Garcia Rivera, senior regional genotyping coordinator at CIMMYT. Watch the recorded session below.

Harnessing new high-resolution satellite imagery to plant breeding

Written by Julian Bañuelos-Uribe on . Posted in Publications.

In plant breeding, efforts to increase the rate of genetic gains and enhance crop resilience to the effects of climate change are often limited by the inaccessibility and costs of phenotyping methods. The recent rapid development of sensors, image-processing technology and data analysis has provided new opportunities for multiple scales phenotyping methods and systems. Among these, satellite imagery may represent one of the best ways to remotely monitor trials and nurseries planted in multiple locations, while standardizing protocols and reducing costs.

This is because relevant data collected as part of crop phenotyping can be generated from satellite images. For instance, the sensors onboard the SkySat satellite constellation of Planet Labs have four spectral bands—blue, green, red, and infrared—which can be used to calculate the normalized difference vegetation index (NDVI), which is a measure of vegetation and its greenness, and various canopy traits like ground cover, leaf area index and chlorosis. It can also be used to monitor plot establishment and phenological parameters.

The use of satellite-based phenotyping in breeding trials has typically been restricted by low resolution, high cost and long intervals between fly-overs. However, the advent of a new generation of high-resolution satellites—such as the SkySat constellation—now offers multispectral images at a 0.5m resolution with close to daily acquisition attempts on any place on Earth. This could be a game changer in terms of the scale at which yield trials can be conducted, enabling more precise variety placement and thereby increasing genetic diversity across farmer’s fields and reducing the probability of disease epidemics. It could also revolutionize the capacity for research in realistic field conditions, since traits can be measured throughout the cycle in a highly standardized way, over multiple sites at low cost. For example, an image which covers 25 km2 can monitor an entire research station at a cost of about US$300.

To test the suitability of this technology, a team of researchers from CIMMYT set out to evaluate the reliability of SkySat NDVI estimates for maize and wheat breeding plots of different sizes and spacing, as well as testing its capacity for detecting seasonal changes and genotypic differences.

Both their initial findings, recently published in Frontiers in Plant Science, and more recently acquired data, show that the SkySat satellites can be used to monitor plots commonly used in wheat and maize nurseries. While wheat yield plots usually are 1.2m wide, maize plots tend to consist of at least two rows, resulting in a width of 1.5m. Plot length ranges from 2-4m. The authors also discuss on other factors to be considered when extracting and interpreting satellite data from yield trials, such as plot spacing.

Through the successful collection of six satellite images in Central Mexico during the rainy season and parallel monitoring of a maize trial in Zimbabwe, the researchers demonstrate the flexibility of this tool. Beyond the improvement of spatial resolution, the researchers suggest that the next challenge will be the development and fine-tuning of operational procedures that ensure high quality, standardized data, allowing them to harness the benefits of the modern breeding triangle, which calls for the integration of phenomics, enviromics and genomics, to accelerate breeding gains.

Steering towards success

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

The inaugural Rwanda National Seed Congress, which took place in Kigali on July 31 and August 1, 2023, marked a significant milestone for the country’s seed industry. Themed “Private Sector Strategic Roadmap for the Seed Industry 2030”, the event brought together key stakeholders from the government, public, and private sectors to address challenges and opportunities in the national seed value chain.

Discussions centered around pertinent issues concerning the seed sector in general, with a particular focus on the Rwandan National Seed Strategic Roadmap. This document, which was developed through consultations with various stakeholders, provides a comprehensive plan to steer the industry towards success and sustainable growth.

“Enhancing and managing the seed system is a complex endeavor that requires the collaboration of various stakeholders,” said Chris Ojiewo, CGIAR Seed Equal Initiative lead. “This is where public-private partnerships come in as a valuable tool for nurturing the growth and expansion of the seed industry.”

During a presentation entitled Public-private Partnership: A Tool for Development and Strengthening of the Seed Sector, Ojiewo highlighted the growing importance of collaboration and partnerships in the current seed system. He emphasized that the processes and elements that shape the seed sector are complex and extensive, making it too much for any one organization—whether public or private—to handle alone.

The way forward

During the congress, several key recommendations were proposed  to increase the potential of the seed industry. The government was encouraged to seek accreditation with major seed industry quality organizations, such as the International Seed Testing Association (ISTA) and Organization for Economic Co-operation and Development (OECD) certification schemes, while adopting International Union for the Protection of New Varieties of Plants (UPOV) to establish an improved regulatory environment conducive to industry growth.

The empowerment of the National Seed Association of Rwanda (NSAR) as an advocate and facilitator for the seed industry was also highlighted as an essential measure. The government’s support in enabling the seed association to become increasingly self-regulatory is seen as crucial to the industry’s growth over the next seven years, with private seed industry players developing internal systems to ensure compliance with rules and regulations.

Another key recommendation for increasing sustainable improved seed use in Rwanda was the use of Public-Private Partnerships (PPPs), which will play a critical role in promoting the country as a seed production and trade investment destination.

Ojiewo emphasized the importance of such partnerships, noting that “PPPs have the potential to transform the seed industry by leveraging the strengths of different organizations.” He further highlighted that in addressing the challenges of global food security and sustainable development, the way forward becomes clear through collaboration, innovation, and a shared commitment to advancing agricultural progress through collaborative efforts.

The congress also focused on attracting affordable financing to scale up investments throughout the seed value chain. It was considered essential to involve industry financial players in the development of optimal financing structures to support the expansion of the industry.

As a result of the successful event, plans have already been made for the second National Seed Congress in 2024. Scheduled to take place in Kigali on July 29 and 30, 2024, the next event aims to build on the achievements of the first congress and further drive the growth of Rwanda’s seed industry.

CGIAR’s Seed Equal Initiative helps farmers by providing them with better seeds that are nutritious, preferred in the market, and that can withstand climate change. These varieties have been carefully developed to exhibit significant genetic advancements, ultimately benefiting farmers. It also makes sure that women and other marginalized groups have fair access to these seeds.

SPG Coalition: CIMMYT is a leading organization for climate-smart agriculture, nutrient-use efficiency, and pest and fertilizer management

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

The Coalition on Sustainable Productivity Growth for Food Security and Resource Conservation (SPG Coalition) brings together researchers, non-governmental organizations, and private sector partners to advance a world with greater access to nutritious food and affordable diets. The Coalition recognizes that increasing the productivity of natural resources through climate adaptation and mitigation is instrumental to reaching this goal.

In a recent report, the SPG Coalition provides a path forward for NGOs, research institutions, and government agencies to strengthen agrifood and climate policies. The report contains real-life, evidence-based examples to further the sustainable production and conservation of natural resources, detailing the potential impacts on social, economic, and environmental conditions.

CIMMYT features prominently in the report as a leading organization focused on 4 main areas: climate-smart agriculture, nutrient-use efficiency (NUE), and pest and fertilizer management.

Nutrient-use efficiency and fertilizer management

While chemical fertilizers increase crop yields, excessive or improper use of fertilizers contributes to greenhouse gas emissions (GHG) and increases labor costs for smallholders. Efficient NUE is central to nutrient management and climate change mitigation and adaptation.

In India, CIMMYT, along with the Borlaug Institute for South Asia (BISA), CGIAR Research Centers, and regional partners, tested digital tools like the Nutrient Expert (NE) decision support tool which measures proper fertilizer use for optimized yields and provides nutrient recommendations based on local soil conditions.

The majority of smallholders who applied the NE tool reported higher yields while emitting less GHG emissions by 12-20% in wheat and by around 2.5% in rice as compared with conventional fertilization practices. Farmers also recorded double economic gains: increased yields and reduced fertilizer costs. Wider government scaling of NE could enhance regional food security and mitigate GHG emissions.

The Feed the Future Nepal Seed and Fertilizer (NSAF) project, led by CIMMYT and USAID, advocates for climate-smart agriculture by linking smallholders with improved seed, providing capacity-building programs, and promoting efficient fertilizer use. With a vast network established with the support from the Government of Nepal, NSAF successfully provides smallholders with expanded market access and nutritious and climate-resilient crop varieties.

Climate-smart maize breeding 

Since its arrival to sub-Saharan Africa (SSA) in 2016, fall armyworm (FAW) has devastated maize harvests for countless smallholders on the continent. Economic uncertainty caused by unstable yields and climate stressors like drought coupled with this endemic pest risk aggravating food insecurity.

CIMMYT and NARES Partner Institutions in Eastern and Southern Africa are spearheading a robust pest management project to develop, screen, and introduce genetically resistant elite maize hybrids across SSA. South Sudan, Zambia, Kenya, and Malawi have already deployed resistant maize varieties, and eight other countries in the region are projected to release their own in 2023. These countries are also conducting National Performance Trials (NPTs) to increase awareness of host plant resistance for the sustainable control of FAW and to sensitize policymakers on accelerating the delivery of FAW-tolerant maize varieties.

The establishment of FAW screening facilities in Africa permits more rapid detection and breeding of maize varieties with native genetic resistance to FAW, facilitating increased deployment of these varieties across Africa. The sustainable control of FAW demands a rapid-response effort, overseen by research organizations and governments, to further develop and validate genetic resistance to fall armyworms. Achieving greater impact for maize smallholders is critical to ensuring improved income and food security in Africa. It is also paramount for biodiversity conservation and removing labor burden on farmers applying additional synthetic pesticides to prevent further losses by the pest.

“The SPG Coalition report emphasizes the power of partnership to enhance financial and food security for smallholder communities in the Global South. This is fully in line with the recently launched CIMMYT 2030 strategy. It’s also an important reminder to assess our strong points and where more investment and collaboration is needed,” said Bram Govaerts, CIMMYT director general.

CIMMYT is pleased to announce the release of a set of 32 new CIMMYT maize lines (CMLs). These maize lines have been developed by CIMMYT’s Global Maize Program by a multi-disciplinary team of scientists in sub-Saharan Africa, Latin America, and Asia. The lines have diverse trait combinations and are suitable for the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions.

CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).

CIMMYT seeks to develop improved maize inbred lines for different product profiles, with superior yield performance, multiple stress tolerance, and enhanced nutritional quality. CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses, besides optimum (non-stress) conditions in the target population of environments. Suitability as either female (seed) or male (pollen) parent is also evaluated. As done in the last announcement of CMLs in 2021, to increase the utilization of the CMLs in the maize breeding programs of the partner institutions, all the new CMLs are tested for their heterotic behavior and assigned to specific heterotic groups of CIMMYT: A and B.

The release of a CML does not guarantee high combining ability or per se performance in all the environments; rather, it indicates that the line is promising or useful as a parent for pedigree breeding or as a potential parent of hybrid combinations for specific mega-environments. The description of the lines includes heterotic group classification, along with information on their specific strengths and their general combining ability with some of the widely used CMLs or CIMMYT coded lines under different environments.

More information:

Summary of the characteristics: CIMMYT maize lines CML616A to CML647A (PDF)

Pedigree and characterization data of all the CMLs released to date, including the latest set (CIMMYT Research Data repository).

Seed for these new set of CMLs will be available from November 1, 2023.  A limited quantity of seed of the CMLs can be obtained by sending a request to the CIMMYT germplasm bank via this link: https://staging.cimmyt.org/resources/seed-request/ or contact, a.chassaigne@cgiar.org.

Food systems in marginal areas of Zimbabwe are vulnerable to climate variability and economic shocks. During the COVID-19 outbreak, governments imposed strict lockdowns that adversely affected local food systems and supply chains. Rural communities that already had difficulty feeding their families found themselves in a more desperate situation. The recurring challenges and the COVID-19 outbreak made it clear that there is a need to transform local food systems to achieve sustainable food and nutrition security. The transition is even more urgent owing to the acute labor shortages due to the accelerated trend of rural labor outmigration and an aging population in smallholder farming communities of the country. Agroecology has emerged as an approach to facilitate and champion a transformative shift to sustainable local food systems.

The Agroecological Initiative is at the forefront of providing science-based evidence for the transformative nature of agroecology and its potential to bring about positive changes in food, land, and water systems, including identifying institutional innovations to promote uptake. Agroecology is a holistic approach to agriculture that emphasizes integrating ecological principles and practices into farming systems. The 13 principles of agroecology guide sustainable and regenerative agricultural practices.

 

Thirteen consolidated agroecology principles (Wezel et al. 2020)

The initiative employs a multi-disciplinary approach, integrating ecological and social methods to co-create and manage localized food systems and monitor the 13 interconnected principles. While agroecological methods hold promise, the transition process is labor and knowledge-intensive and requires addressing power dynamics within and beyond households to address food and nutrition security. Building on the findings of the completed ACIAR-funded project Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) and Harnessing Appropriate-scale Farm Mechanization in Zimbabwe (HAFIZ), CIMMYT is working in Zimbabwe with 200+ farmers and four service providers in Murehwa and Mbire districts as ambassadors of the community through Agroecological Living Landscapes (ALLs).

Mechanization plays a crucial role in the initiative implementation in Zimbabwe, covering a wide range of farming and processing equipment. The equipment ranges from simple and basic hand tools to more sophisticated and motorized tools. The machinery eases and reduces drudgery associated with agricultural practices, relieves labor shortages, improves productivity and timeliness of agricultural operations, optimizes resource utilization, enhances market access, and helps mitigate climate-related hazards.

“Machinery supports synergies, reduces labor, and reduces human and wildlife conflict as it reduces livestock grazing time because you can now make feed for your cattle and cutting grass reduces veld fires,” said Musandaire.

Within the Agroecology Initiative, CIMMYT considers mechanization in its technological, economic, social, environmental and cultural dimensions when contributing to the sustainable development of localized food systems and actors. In Mbire and Murehwa, a service provider model was adopted to introduce appropriate scale machinery within the respective communities. The service providers were equipped with a two-wheel tractor, ripper, mower, chopper grinder, and bailer. Training was offered on equipment operation, repair, and maintenance.

The business aspects were also discussed to broaden the participants’ knowledge of service provision. Important aspects covered include business model, entrepreneurship, record keeping, cost and profit calculations, customer care, target setting, and machinery operation planning.

To date, the service providers offer services including ripping, transportation, chopper grinding for livestock feeds and humans, and baling and mower for grass cutting at a fee.

“Mechanization has proven efficient and relevant in our district since livestock is one of our main value chains. Our service providers make hay bales for us, which we buy to feed our livestock. They also grind feed which is good for pen-fattening,” said Chimukoro, councilor in Mbire.

Preliminary findings indicate that appropriate scale mechanization enhances synergies in smallholder farming systems by facilitating more efficient and integrated agricultural practices.

“Our trailer reduces labor and saves time better than scotch carts. We used to leave much biomass in the fields because we didn’t know how to transport and process it after aggregation. But now we can recycle our biomass,” mentioned Mushaninga, local leadership in Murehwa.

By streamlining labor-intensive tasks and promoting holistic farm management, mechanization encourages complementarity among various elements of agroecosystems, contributing to more sustainable and productive smallholder farming. Target communities can pave the way for a more resilient and sustainable food system through the Agroecological Initiative.

Research local: co-creation generates novel options to tackle global problems

Written by Julian Bañuelos-Uribe on . Posted in Publications.

The United Nations Sustainable Development Goals (SDG) are broad mandates for transitioning to fair and sustainable agrifood systems. However, because of their global view, they often operate at a scale not clearly seen or understood by local stakeholders.

New research led by the International Maize and Wheat Improvement Center (CIMMYT) scientists offers participatory action research (PAR) as a potential bridge between the macro scope of the SDGs and the needs and desires of local communities.

The article, Participatory action research generates knowledge for Sustainable Development Goals, published in the June 2023 issue of Frontiers in Ecology and the Environment, examines two decades of participatory action research activities in Malawi, a highly rural society dependent on rainfed agriculture.

“Participatory research is known for giving voice to farmers, for accelerating adaptation and for impact,” said lead author Sieglinde Snapp, director of the Sustainable Agrifood Systems program at CIMMYT. “What is novel in this study is that new discoveries were documented, showing the scientific contributions possible through PAR.”

Co-creation

Participatory action research is a knowledge generation process, characterized by a series of steps to facilitate improved understanding and development of innovations, within a local context. The PAR approach involves engaging stakeholders, to co-create solutions with researchers.

Because knowledge is often local, access to natural resources is highly heterogeneous, climate variability is unpredictable and socioeconomic circumstances are context-dependent, any intervention must be flexible and locally specific to ensure sustainability.

PAR prioritizes empowerment of marginalized communities to build long-term partnerships which support transformational changes at local, regional and national levels.

Yet the evidence base for PAR methodology remains fragmented and is often inaccessible.

“This is the first paper that shows how action research produces new knowledge through a systematic, iterative process that derived ‘middle ways’, such as shrubby food crops as a farmers preferred form of agroforestry,” said Snapp.

Solving wicked problems

Participatory research is well-suited to address conflicts and trade-offs that are key aspects of so-called wicked problems. For instance, annual crops—maize and soybean—are excellent producers of food but feature limited aboveground vegetation and belowground activity to regenerate soil nutrients, while perennials provide soil regeneration services but no food products.

By engaging closely with local stakeholders, PAR identifies “goldilocks options,” or middle ways, such as semi-perennial shrubs and vines that produce food while also promoting soil health.

Genetic and agronomic improvement efforts have almost entirely overlooked semi-perennial plant types to address food–soil trade-offs.

Challenges

Building relationships between researchers and stakeholders; the investment required in selecting representative sites, action learning activities, synthesis of findings, communication and documentation; and the inherent variability of research conducted under real-world conditions are barriers to establishing PAR systems. Living laboratories and education on PAR approaches need investment. Reward structures may need to shift, with greater attention to considering research impact on SDGs and awareness that time lags may occur in publishing scientific findings through PAR.

“Our findings detailing the efficacy of PAR shows that the potentially high upfront costs to invest in relationship building and learning across disciplines, this is a worthwhile trade-off,” said Snapp.

Through PAR, human condition and social-science questions can be addressed, along with biological and environmental science questions, as illustrated in this Malawian case study.

The findings generated by PAR have relevance beyond the sub-Saharan Africa context because they provide new insights into the development of nature-based solutions that meet local needs, a critical requirement for rural communities in many parts of the globe.
