CGIAR Initiative on Diversification in East and Southern Africa

Written by Julian Bañuelos-Uribe on November 27, 2023. Posted in Uncategorized.

East and Southern Africa is a climate hotspot, with more than US$45 billion in agricultural production at risk from higher temperatures, shorter growing seasons and more extreme droughts and floods. Maize, a staple crop covering up to 75% of cropland in parts of the region, is particularly vulnerable and is projected to face yield declines of 15%, among other climate impacts if no adaptation measures are taken. Many of the affected areas already have serious levels of hunger and malnutrition, with the highest burden experienced by women and youth from marginalized and vulnerable communities. If these systems are sustainably diversified, they can contribute to stabilizing regional and global agrifood systems.

The next decade will be critical for strengthening food, land and water systems in East and Southern Africa. The agribusiness ecosystem for both regions has been identified as a critical engine for agricultural and economic development, climate change adaptation and gender and youth empowerment. Investment in innovation, capabilities and supportive environments will be essential for driving sustainable growth.

Objective

This Initiative aims to support climate-resilient agriculture and livelihoods in 12 countries in East and Southern Africa by helping millions of smallholders intensify, diversify and reduce the risks in maize-based farming through improved extension services, small and medium enterprise development, supporting governance frameworks and increased investment with a gender and social inclusion lens.

Activities

This objective will be achieved through:

Diversifying and sustainably intensifying production by assessing needs and options for the introduction of crops, livestock, mechanization and irrigation, applying innovations in value chains and building capacity while scaling to larger farming communities.
Reducing risk and digitalizing value chains by co-designing and delivering “Innovation Package” bundles of digital agro-advisory systems and research management products — including mobile apps, TV programs and social media — to build resilience and improve productivity.
Supporting and accelerating value chain business enablers in maize mixed systems by using CGIAR’s expertise and partner network to unlock access to funding, investment and tailored technical assistance.
Promoting the governing and enabling of multifunctional landscapes for sustainable diversification and intensification with a focus on strengthening the evidence base for decision-makers.
Empowering and engaging women and youth in agribusiness ecosystems by mapping challenges and opportunities to address gender and social inequality and applying inclusive and coordinated interventions for transformative change.
Scaling innovations and coordinating CGIAR and partner activities in the region through a scaling hub that uses the “scaling readiness” approach to inform, activate and bring to scale innovations that respond to regional or country demand.

CIMMYT leads innovation sprint to deliver results to farmers rapidly

Written by Sarah McLaughlin on December 5, 2022. Posted in Features.

Smallholder farmers, the backbone of food systems around the world, are already facing negative impacts because of climate change. Time to adapt climate mitigation strategies is not a luxury they have. With that in mind, the Agriculture Innovation Mission for Climate (AIM4C) facilitates innovation sprints designed to leverage existing development activities to create a series of innovations in an expedited timeframe.

At the UN COP27 in Egypt, AIM4C announced its newest round of innovation sprints, including one led by the International Center for Maize and Wheat Improvement (CIMMYT) to enable smallholder farmers to achieve efficient and effective nitrogen fertilizer management. From 2022 to 2025, this sprint will steer US $90 million towards empowering small-scale producers in Africa (Kenya, Malawi, Morocco, Tanzania, and Zimbabwe), Asia (China, India, Laos and Pakistan), and Latin America (Guatemala and Mexico).

“When we talk to farmers, they tell us they want validated farming practices tailored to their specific conditions to achieve greater productivity and increase their climate resilience,” said Sieg Snapp, CIMMYT Sustainable Agrifood Systems (SAS) program director who is coordinating the sprint. “This sprint will help deliver those things rapidly by focusing on bolstering organic carbon in soil and lowering nitrous oxide emissions.”

Nitrogen in China

Working with the Chinese Academy of Agricultural Sciences (CAAS), the sprint will facilitate the development of improved versions of green manure crops, which are grown specifically for building and maintaining soil fertility and structures which are incorporated back into the soil, either directly, or after removal and composting. Green manure can significantly reduce the use of nitrogen-based fertilizers, which prime climate culprits.

“There are already green manure systems in place in China,” said Weidong Cao from CAAS, “but our efforts will integrate all the work being done to establish a framework for developing new green manure crops aid in their deployment across China.”

Triple wins in Kenya

The Kenya Climate Smart Climate Project, active since 2017, is increasing agricultural productivity and building resilience to climate change risks in the targeted smallholder farming and pastoral communities. The innovation sprint will help rapidly achieve three wins in technology development and dissemination, cutting-edge innovations, and developing sets of management practices all designed to increase productive, adaption of climate smart tech and methods, and reduce greenhouse gas (GHG) emissions.

Agricultural innovations in Pakistan

The Agricultural Innovation Program (AIP), a multi-disciplinary and multi-sectoral project funded by USAID, led by CIMMYT, and active in Pakistan since 2015, fosters the emergence of a dynamic, responsive, and competitive system of science and innovation that is ‘owned’ by Pakistan and catalyzes equitable growth in agricultural production, productivity, and value.

“From its beginning, AIP has been dedicated to building partnerships with local organizations and, smallholder farmers throughout Pakistan, which is very much in line with the objectives and goal as envisioned by Pakistan Vision 2025 and the Vision for Agriculture 2030, as Pakistan is a priority country for CIMMYT. However, a concerted effort is required from various players representing public and private sectors,” said Thakur Prasad Tiwari, senior scientist at CIMMYT. “Using that existing framework to deliver rapid climate smart innovations, the innovation sprint is well-situated to react to the needs of Pakistani farmers. “

Policies and partnerships for innovations in soil fertility management in Nepal

The Nepal Seed and Fertilizer (NSAF) project, funded by USAID and implemented by CIMMYT, facilitates sustainable increases in Nepal’s national crop productivity, farmer income, and household-level food and nutrition security. NSAF promotes the use of improved seeds and integrated soil fertility management technologies along with effective extension, including the use of digital and information and communications technologies. The project facilitated the National Soil Science Research Centre (NSSRC) to develop new domain specific fertilizer recommendations for rice, maize, and wheat to replace the 40 years old blanket recommendations.

Under NSAFs leadership, the Ministry of Agriculture and Livestock Development (MOALD) launched Asia’s first digital soil map and has coordinated governmental efforts to collect and analyze soil data to update the soil map and provide soil health cards to Nepal’s farmers. The project provides training to over 2000 farmers per year to apply ISFM principles and provides evidence to the MOALD to initiate a balanced soil fertility management program in Nepal and to revise the national fertilizer subsidy policy to promote balanced fertilizers. The project will also build efficient soil fertility management systems that significantly increase crop productivity and the marketing and distribution of climate smart and alternative fertilizer products and application methods.

Public-private partnerships accelerate access to innovations in South Asia

The Cereal Systems Initiative for South Asia (CSISA), established in 2009, has reached more than 8 million farmers by conducting applied research and bridging public and private sector divides in the context of rural ‘innovation hubs’ in Bangladesh, India, and Nepal. CSISA’s work has enabled farmers to adopt resource-conserving and climate-resilient technologies and improve their access to market information and enterprise development.

“Farmers in South Asia have become familiar with the value addition that participating in applied research can bring to innovations in their production systems,” said Timothy Krupnik, CIMMYT systems agronomist and senior scientist. “Moreover, CSISA’s work to address gaps between national and extension policies and practices as they pertain to integrated soil fertility management in the context of intensive cropping systems in South Asia has helped to accelerate farmers’ access to productivity-enhancing innovations.”

CSISA also emphasizes support for women farmers by improving their access and exposure to improved technological innovations, knowledge, and entrepreneurial skills.

Sustainable agriculture in Zambia

The Sustainable Intensification of Smallholder Farming systems in Zambia (SIFAZ) is a research project jointly implemented by the UN Food and Agriculture Organization (FAO), Zambia’s Ministry of Agriculture and CIMMYT designed to facilitate scaling-up of sustainable and climate smart crop production and land management practices within the three agro-ecological zones of Zambia. “The Innovation Sprint can take advantage of existing SIFAZ partnerships, especially with Zambia’s Ministry of Agriculture,” said Christian Thierfelder, CIMMYT scientist. “Already having governmental buy-in will enable quick development and dissemination of new sustainable intensification practices to increase productivity and profitability, enhance human and social benefits while reducing negative impacts on the environment.”

The Accelerated Varietal Improvement and Seed Delivery of Legumes and Cereals in Africa (AVISA) project has developed draft national groundnut target product profiles in Malawi, Mozambique, Sudan, Tanzania, Uganda and Zambia.

Groundnut is grown in eastern and southern Africa, where it remains an important food and oil crop from small holder farmers.

The new findings from the project are a result of work from groundnut crop breeding and improvement teams from the National Agricultural Research and Extension Systems (NARES) representatives from the six largest groundnut producing countries in the eastern and southern Africa region.

Their important research was carried out with the support of representatives from the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) and CGIAR.

Developing target product profiles for groundnut

For the first time, through the International Maize and Wheat Improvement Center (CIMMYT)-led AVISA program, funded by the Bill & Melinda Gates Foundation, groundnut breeding teams discussed and documented country level priorities at a meeting in Dar es Salaam, Tanzania.

Their findings were developed using a standard target product profile template recently developed by CGIAR Excellence in Breeding (EiB) in conjunction with CGIAR’s Market Intelligence Initiative. The template serves as a tool to capture market segments and develop targeted product profiles.

The groundnut breeding teams also shared information on current groundnut production metrics and trends in the six national programs. This also helped to establish a common understanding of countries’ level research priorities.

Agnes Gitonga, market strategist at CGIAR Genetic Innovations Action Area, who led the team in understanding and applying the template, explained that the quality of a target product profile (TPP) is dependent on how well market segments are defined. “To ensure target product profiles are an accurate reflection of customer needs, who include farmers, consumers, and processors,” she said.

“National groundnut teams nominated Country Product Design Teams that will meet nationally before the end of 2022 to review and update country TPPs. These multi-stakeholder teams will ensure that the needs of diverse groups are captured and that breeding efforts are accurately focused.”.

Harish Gandhi, Breeding Lead, Dryland Legumes and Cereals (DLC) at CIMMYT, further explained that a bottom-up approach for defining country and regional priorities was used, where each country defined market segments and target product profile based on the use of the produce and growing conditions of farmers. This strategy involved each country defining its market segments and TPP, which was based on the use of the produce and growing conditions of farmers.

Building on the draft national target product profiles that were defined at the meeting, participants went on to prioritize traits such as diseases, nutrition and stress tolerance. These factors can be critical at regional level and important in identifying potential locations for conducting phenotyping. The phenotyping locations are distributed based on capacity of stations in different countries to screen for traits, such as late leaf spot disease screening in Msekera in Zambia, which is a known hotspot for the disease.

“We had a good opportunity to consider grower needs as well as consumer needs in each country for purposes of defining the relevant groundnuts market segments. I believe this will have a positive impact on future work in groundnuts in the East and Southern Africa region,” reflected Gitonga.

The collaboration of the teams involved was a key factor for the project’s success so far and will be crucial in working towards its goals in the future.

“Involving different stakeholders in designing target product profile was an effective way of enabling transformation of individual preferences (area of interest) to collective preferences (targeted product) with consumer needs and markets in mind,” said Happy Daudi, Groundnut Breeding lead at the Tanzania Agricultural Research Institute (TARI).

Strengthening groundnut breeding programs in east and southern Africa

The project’s first meeting will provide an important foundation for future research, which will use the new findings as a blueprint.

Biswanath Das, Plant Breeder, Groundnut for East and Southern Africa region and NARES Coordinator and Programming lead for EiB said, “Defining national TPPs, identifying regionally important traits and mapping a testing network are fundamental building blocks of a modern breeding program.”

At the meeting, a schedule was laid out for peer-to-peer assessments of breeding programs within the regional network to take stock of current efforts and gaps. This step helps to develop customized capacity development plans for each network partner.

“Through targeted and demand led capacity development, the East and Southern Africa groundnut crop improvement network aspires to strengthen the role of each network member in collaborative, regional breeding efforts,” Das said.

The meeting laid the ground for coordinated regional groundnut breeding and took steps towards formalizing a regional NARES-CGIAR-SME groundnut crop improvement network. By building on excellent connections that already exist among national groundnut breeding teams. Das underscored that the move will strengthen alignment of NARES, CGIAR and regional research efforts around a common vision of success.

In addition, David Okello who leads groundnut research at National Agriculture Research Organization (NARO) Uganda, noted that the meeting provided a good opportunity for consolidating the existing network. He also looked forward to welcoming more groundnut improvement programs in the region on board.

New CGIAR Initiative to catalyze resilient agrifood systems in eastern and southern Africa

Written by Rodrigo Ordóñez on May 9, 2022. Posted in News.

Partners of CGIAR’s new regional integrated Initiative in eastern and southern Africa held a kick-off meeting in Nairobi on March 2–3, 2022. Eighty-five people participated, including national agricultural research extension programs, government representatives, private sector actors, funders and national and regional agricultural research and development organizations.

Entitled Ukama Ustawi, the Initiative aims to support climate-smart agriculture and livelihoods in 12 countries in eastern and southern Africa: Kenya, Zambia, Ethiopia and Zimbabwe (in Phase 1); Malawi, Rwanda, Tanzania and Uganda (in Phase 2); and Eswatini, Madagascar, Mozambique and South Africa (in Phase 3).

The Initiative aims to help millions of smallholders intensify, diversify and de-risk maize-mixed farming through improved extension services, institutional capacity strengthening, targeted farm management bundles, policy support, enterprise development and private investment.

Ukama Ustawi is a bilingual word derived from the Shona and Swahili languages. In Shona, Ukama refers to partnerships, and in Swahili, Ustawi means well-being and development. Together, they resemble the vision for the Initiative to achieve system-level development through innovative partnerships.

The meeting brought together partners to get to know each other, understand roles and responsibilities, identify priorities for 2022, and review the cross-cutting programmatic underpinnings of Ukama Ustawi — including gender and social inclusion, capacity strengthening and learning.

Baitsi Podisi, representing the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA), said he is excited to be part of the Initiative: “CCARDESA, in its cooperation and coordination mandate, can learn a lot from CGIAR in restructuring to respond to the changing times.” Podisi supported the partnership with CGIAR in the Initiative’s embedded approach to policy dialogue, working with partners such as CCARDESA, the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) and the Food, Agriculture and Natural Resources Policy Analysis Network (FANRPAN).

Similarly, FANRPAN’s Francis Hale emphasized the need not to re-invent the wheel but to work with partners who already have a convening power, to advance the policy agenda for diversification and sustainable intensification.

What were key issues discussed?

One of the features of Ukama Ustawi is the use of four interconnected platforms: a scaling hub, a policy hub, an accelerator program and a learning platform. These will provide spaces for exchange and learning with partners across all CGIAR Initiatives in the region. Partners conducted a series of ‘fishbowl’ interactions across work packages to review the planned activities and provide a clearer understanding of deliverables, identify synergies, potential overlaps, common partners and countries, and set timelines.

The Initiative will work with innovative multimedia platforms to change knowledge, attitudes and practices of millions of farmers in eastern and southern Africa. One key partner in this area is the Shamba Shape Up TV show and the iShamba digital platform. Sophie Rottman, Producer of Shamba Shape Up, said she is looking forward to the work with Initiative partners, that will help expand the show to Uganda and Zambia.

Jean Claude Rubyogo, representing the Pan-Africa Bean Research Alliance (PABRA) said: “It is time we move away from CGIAR-initiated to country-initiated development activities. This is what Ukama Ustawi is all about”.

Martin Kropff, Global Director of Resilient Agrifood Systems at CGIAR, explained CGIAR’s regional integrated initiatives are designed to respond to national/regional demands. “The initiatives will start by working with partners to assess the food and nutritional challenges in the region, and tackle them by bringing in innovative solutions.”

The event was concluded by agreeing on the implementation of the inception phase of the Ukama Ustawi Initiative, and follow-on discussions to finalize key activities in 2022.

CIMMYT and IITA collaborate to increase adoption of conservation agriculture in southern Africa

Written by Rodrigo Ordóñez on September 21, 2020. Posted in Press releases.

The International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) recently launched a project that aims to research the drivers and barriers to adoption of conservation agriculture in southern Africa, and to develop strategies for achieving adoption and impact at scale.

The project, Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA), will apply social and scaling science to understand the biophysical, socioeconomic, institutional, and policy drivers and barriers to the adoption of conservation agriculture technologies and practices.

The ACASA project is supported by the Norwegian Agency for Development Cooperation (Norad) and will be implemented in Malawi, Zambia, and Zimbabwe in collaboration with partners and farmers in the region.

The project was officially launched online on September 16, 2020. Zambia’s Minister of Agriculture, Michael Katambo, noted that it is a timely intervention, as the livelihoods and food security of smallholder farmers in southern Africa are increasingly being threatened by climate change and variability, which have led to a steady decline in the production of food staples and an increase in the number of food and nutrition-insecure people.

“It is now clear that current productivity and production levels cannot be expected to meet our requirements for food and nutrition security,” Katambo said in a speech read on his behalf by Moses Mwale, Director of the Department of Agriculture. “Conservation agriculture has a proven potential to increase and stabilize crop yields, and to support sustainable and resilient production systems and rural livelihoods.”

Proven benefits

Conservation agriculture — a farming system that promotes minimum soil disturbance, permanent soil cover and diversification of plant species — can efficiently increase agricultural productivity while reducing land degradation and improving soil health for more productive, profitable, and sustainable farming.

Substantial on-farm evidence has been generated on the agronomic and economic benefits of conservation agriculture, first introduced in the 1970s in South Africa. Consequently, donors and governments have made a lot of investments to promote and scale conservation agriculture technologies and practices among smallholder farmers in the region. Despite all these efforts, however, the adoption rate among smallholder farmers remains low.

“We should not let the low adoption of conservation agriculture discourage us. Let us use this opportunity to reflect and identify the missing link and come up with more sustainable solutions to the problem,” said the IITA Director for Southern Africa, David Chikoye.

“Although adoption of improved practices by most resource-poor farmers is primarily determined by the potential immediate benefits on crop yields, profits, risk, and livelihoods, there are a number of biophysical, socioeconomic, institutional, and policy factors that promote or hinder adoption of conservation agriculture. The project, therefore, aims to identify the adoption drivers and barriers, and to develop pathways and strategies for inclusive scaling of conservation agriculture practices,” said Arega Alene, Agricultural Economist at IITA and leader of the ACASA project.

Christian Thierfelder, Principal Cropping Systems Agronomist at CIMMYT, highlighted some of the bottlenecks for conservation agriculture adoption, noting they were linked more to socioeconomic and cultural factors rather than biophysical. “Conservation agriculture is a viable and proven climate-smart farming system. Future research efforts should go towards understanding farmers’ decision-making and behavioral change, as well as profitability,” Thierfelder said.

Other key partners include the Food and Agriculture Organization of the United Nations (FAO), the African Conservation Tillage Network (ACT) and Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA).

The project launch was attended by policymakers, donors, members of national and regional conservation agriculture taskforces, national and international research institutions, universities, international development institutions, private seed companies, non-governmental organizations, and farmer organizations.

Luganu Mwangonde (center, holding a microphone) shares her experience in climate-smart agriculture to inspire the next generation of farmers in Malula, Balaka District, Malawi.

Equal and climate-smart

Written by Shiela Chikulo on March 6, 2020. Posted in Features.

Sixteen years of consistent learning and practice of climate-smart agriculture, led by the International Maize and Wheat Improvement Center (CIMMYT), are paying off for Luganu Mwangonde. Together with her husband Kenson, she has established herself as a successful smallholder farmer in Malawi’s Balaka district. She enjoys the multiple benefits of high yields from diverse crops, surplus to sell at the markets and improved soil quality.

“I started practicing the farming that does not demand too much labor back in 2004,” she explains at her 2.5-acre farm. “Over the years the process has become easier, because I have a full understanding of the benefits of techniques introduced through the project.”

In Malawi’s family farms, women often carry the burden of land preparation and weeding in the fields while juggling household responsibilities, contributing to widen gender differences already prevalent in the community.

Mwangonde observes that learning climate-smart techniques — such as minimum tillage, mulching and planting on flat land surfaces — has given her an advantage over other farmers practicing conventional agriculture.

Better off

At the beginning, like other farmers in the area, Mwangonde thought conservation agriculture and climate-smart techniques required a lot of work, or even hiring extra labor. As she tried this new approach, however, weed pressure in her plot decreased gradually, with the help of mulching and other techniques, and the labor required to maintain the fields reduced significantly. This allowed her to have extra time to add value to her products and sell them on the markets — and to rest.

The best gain for her is knowing that her family always has enough to eat. “I have enough grain to last until the next harvest,” she says. “My husband and I can provide for our seven children and four grandchildren.” During the 2018/19 season, Mwangonde’s family harvested six bags of maize, two bags of pigeon pea and four bags of groundnuts. The surplus from the harvest is reserved for later, when prices are more competitive.

“I am an equal partner in the farming activities. That means I can make decisions about how we work on our plot, distribute crops and apply everything that I have learnt about conservation agriculture,” Mwangonde explains. She has participated in CIMMYT activities where she could share her experiences on climate-smart agriculture with other women. As a lead farmer, she notes, she can confidently inspire the next generation of smallholders because of the empowering knowledge she has acquired.

Out of the 3,538 smallholder farmers from Balaka, Machinga and Zomba districts, up to 2,218 are women smallholder farmers who have successfully adopted climate-smart technologies.

Mwangonde is one of the beneficiaries of the Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) project. She also benefitted from the support of the German Development Agency (GIZ), the International Fund for Agricultural Development (IFAD), Total Land Care (TLC) and the United States Agency for International Development (USAID).

Nurture soil as our food and climate insurance

Written by Jérôme Bossuet on December 5, 2019. Posted in Features.

Kassim Massi and Joyce Makawa have learned how conservation agriculture nurtures the soil of their 2.5-acres farm in Lemu, Malawi, and helps them to better cope with regular dry spells and storm rains. With four children and two grandchildren, their livelihoods depend on rainfed crop farming, in particular maize, the main staple in Malawi, and a few goats and free-range poultry. The International Maize and Wheat Improvement Center (CIMMYT) introduced them to conservation agriculture, along with five other families in their community.

“I have learnt a lot from this experiment. I can see that with crop rotation, mulching and intercropping I get bigger and healthier maize cobs. The right maize spacing, one seed at the time planted in a row, creates a good canopy which preserves the soil moisture in addition to the mulch effect,” Massi explains. “The mulch also helps to limit water runoff when there are heavy rains. I don’t see the streams of mud flowing out of this plot like for my other field where I only planted maize as usual on ridges,” he adds.

Massi and Makawa started small, on a quarter acre, testing maize and maize-pigeon pea intercropping under conservation agriculture. Later they diversified to a maize-groundnut rotation with pigeon pea alleys, while introducing different drought-tolerant maize varieties on their plot. Pigeon pea and groundnut are legume crops that enrich the soil in nitrogen via nodules that host specific bacteria called rhizobia in their root systems. Massi and Makawa also put layers of maize stalks and groundnut haulms on the ground after harvest, creating a mulch that not only enriches the soil in organic matter but retains soil moisture and improves soil structure.

While they got only two bags of 50kg maize grain from their conventionally tilled maize field, they harvested almost three times more maize grain plus three bags of groundnuts, and two and half bags of pigeonpea from the 0.1 hectares grown under conservation agriculture. “This plot has become our food insurance and we plan to expand it.”

Good for the soil and good for the farmer

“Building healthy soils over the years is one of the great impacts of conservation agriculture,” explains Christian Thierfelder, an agronomist with CIMMYT in Zimbabwe. “With no tillage, legume rotation or intercropping and crop residue management, a beneficial soil pore structure is developed over time. This enables water to infiltrate into the soil where it is available for plant growth in times of drought or during in-season dry spells.”

Under the GIZ-funded Out scaling climate-smart technologies to smallholder farmers in Malawi, Zambia & Zimbabwe initiative, the different ecosystem services that soils bring have been measured against the typical ploughed maize monocropping system. Fifteen year-long experiments show that 48.5mm more water infiltrates per hour under no-till as compared with the conventional method. Soil erosion is reduced by 64% for ripline-seeded maize with legume intercropping. At the Henderson Research station in Zimbabwe where soil erosion loss has been quantified, it means 90 metric tons per hectare of topsoil saved over twelve years.

“Conservation agriculture is good for the soil, and it is good for the farmer. The maize-legume intercropping under conservation agriculture provides very good financial return to labor and investment in most rural communities we worked with,” Thierfelder notes.

Climate mitigation or resilience?

There is growing recognition of the importance of soils in our quest for sustainability.

Soils play for instance an important role in climate regulation. Plants fix carbon dioxide (CO₂) through photosynthesis and when those plants die and decompose, the living organisms of the soil, such as bacteria, fungi or earthworms, transform them into organic matter. That way, soils capture huge quantities of the carbon emissions that fuel climate change. This soil organic carbon is also essential for our food security because it retains water, and soil nutrients, essential for growing crops.

The quantity of carbon soils capture depends on the way farmers grow their crops. Conservation agriculture improves soil biodiversity and carbon sequestration by retaining crop residues as mulch, compared to conventional practices.

“Research shows that practices such as conservation agriculture can restore soil organic carbon at the level of four per thousand when farmers apply all principles of conservation agriculture: no-till, soil cover and crop diversification,” explains Marc Corbeels, agronomist seconded to CIMMYT from Cirad. Increasing soil organic content stocks globally by 0.4% per year is the objective of the “4 per 1000” initiative as a way to mitigate climate change and improve food security. At global level, sequestrating 0.4% more soil organic carbon annually combined with stopping deforestation would counteract the annual rise in atmospheric CO2.

“The overall soil organic carbon sequestration potential of conservation agriculture should however not be overestimated,” Corbeels warns. “Carbon sequestration is complex and context-specific. It depends for instance on the type of soils and the initial soil organic status, and the crop and biomass productivity as enough crop residues should be produced.”

“Now farmers in Malawi, Zambia and Zimbabwe are facing prolonged drought and, in some parts, farming communities got hit by flash floods. With degraded and barren soils in this tropical environment, it is a disaster. In my experience, more than mitigation, improved climate resilience is a bigger benefit of conservation agriculture for the farmers”, Corbeels says.

“Science is important to build up solid evidence of the benefits of a healthy soil and push forward much-needed policy interventions to incentivize soil conservation,” Thierfelder states.

Scaling out conservation agriculture practices is what has driven him over the past decade in southern Africa.

“One big lesson I learnt from my years of research with farmers is that if you treat well your soil, your soil will treat you well. Conservation agriculture adopters like Kassim Massi and his family are more resilient to these successive shocks. We need more farmers like them to achieve greater food security and climate resilience in the region,” he concludes.

December 5, we are celebrating World Soil Day under the theme “Stop Soil Erosion, Save our Future!” As CIMMYT’s research shows, farmers cannot deliver sustainable food security without healthy soils, as the farming land producing our staple crops provide important environmental services as well. CIMMYT calls for soil-smart agriculture and food systems.

Scaling out climate-smart agriculture in southern Africa

Written by Emma Orchardson on December 3, 2019. Posted in Infographics.

The United Nations Framework Convention on Climate Change estimates that temperatures in Africa are set to rise significantly in coming years, with devastating results for farmers. Some regions could experience two droughts every five years, and see drastic reductions in maize yields over the next three decades.

Research demonstrates that climate-smart agriculture (CSA) is good method of mitigating the effects of climate change, for both farmers and the planet. Associated practices, which increase soil moisture levels and soil biodiversity have been shown to decrease soil erosion by up to 64%. They also have the potential to increase maize yields by 136% and incomes in dry environments by more than twice as much.

However, adoption rates remain low in some of the countries which stand to benefit the most, such as Malawi, Zambia and Zimbabwe, where the adoption of complete conservation agriculture systems is currently at 2.5%.

A new series of infographics describes some of the farming constraints will have to be addressed in order to scale climate-smart agricultural practices successfully in the region, taking into account both benefits and challenges for farmers.

Mary Twaya is an exemplary farmer in Lemu, a rural drought-prone community in southern Malawi, near Lake Malombe. On her one-hectare farm she grows cotton, maize, and legumes like groundnut and cowpea, which she just picked from her fields. Since agriculture is Twaya’s sole livelihood, it is important for her to get good harvests, so she can support her three children and her elderly mother. She is the only breadwinner since her husband left to sell coffee in the city and never returned.

Agriculture is critically important to the economy and social fabric of Malawi, one of the poorest countries in the World. Up to 84% of Malawian households own or cultivate land. Yet, gender disparities mean that farmland managed by women are on average 25% less productive than men. Constraints include limited access to inputs and opportunities for capacity building in farming.

Climate change may worsen this gender gap. Research from the International Maize and Wheat Improvement Center (CIMMYT) shows that there are multidimensional benefits for women farmers to switch to climate-smart agriculture practices, such as planting drought-tolerant maize varieties and conservation agriculture with no tillage, soil cover and crop diversification.

Twaya was part of a CIMMYT project that brought climate-smart agriculture practices to smallholder farmers in Malawi, Zambia and Zimbabwe.

She was enthusiastic about adopting climate-smart agriculture practices and conservation agriculture strategies in her plot. “I have always considered myself an active farmer, and when my husband left, I continued in the project around 2007 as part of the six lead ‘mother farmers’ with about 30 more ‘baby farmers’ learning through our field trials,” Twaya explained.

“We worked in Lemu since 2007 with Patrick Stanford, a very active and dedicated extension officer who introduced conservation agriculture to the village,” said CIMMYT agronomist Christian Thierfelder. “Farmers highlighted declining yields. The Lemu community was keen to transform their farming system, from conventional ridge tillage to more sustainable and climate-adapted cropping systems.” This was an ideal breeding ground for new ideas and the development of climate-smart solutions, according to Thierfelder.

Mulching, spacing and legume diversification

Showing her demonstration plot, which covers a third of her farm, Twaya highlights some of the climate-smart practices she adopted.

“Mulching was an entirely new concept to me. I noticed that it helps with moisture retention allowing my crops to survive for longer during the periods of dry spells. Compared to the crops without mulching, one could easily tell the difference in the health of the crop.”

“Thanks to mulching and no tillage, a beneficial soil structure is developed over time that enables more sustained water infiltration into the soil’’, explained Thierfelder. “Another advantage of mulching is that it controls the presence of weeds because the mulch smothers weeds unlike in conventional systems where the soil is bare.”

Research shows that conservation agriculture practices like mulching, combined with direct seeding and improved weed control practices, can reduce an average of 25-45 labor days per hectare for women and children in manual farming systems in eastern Zambia and Malawi. This time could be used more productively at the market, at home or in other income-generating activities.

After 12 years of practicing conservation agriculture, Twaya confirms that she does not spend too much time in the field because she just uproots the weeds with no need for using a hoe. This makes the weeding task less laborious and allows her to spend her time on other chores such as fetching water, washing laundry or cleaning her homestead. “I have time to also go to the village banking and loan savings club to meet with others”.

Adopting optimum plant density, instead of throwing in three seeds in each planting hole was another transformational change. The “Sasakawa spacing” — where maize seeds are planted 25 centimeters apart in rows spaced every 75 centimeters — saves seed and boosts yields, as each plant receives adequate fertilizer, light and water without competing with the other seeds. This practice was introduced in Malawi in the year 2000 by Sasakawa Global.

Twaya pays more attention to the benefits of planting nitrogen-fixing crops alongside her maize, as she learned that “through crop rotation, legumes like pigeon pea improve the nutrition of my soil.” In the past she threw pigeon pea seeds loosely over her maize field and let it grow without any order, but now she practices a “double-up legume system,” where groundnut and pigeon pea are cropped at the same time. Pigeon peas develop slowly, so they can grow for three months without competition after groundnut is harvested. This system was introduced by the Africa RISING project, funded by USAID.

A mother farmer shows the way

Switching to climate-smart agriculture requires a long-term commitment and knowledge. Some farmers may resist to the changes because they initially find it new and tedious but, like Twaya observed, “it may be because they have not given themselves enough time to see the long-term benefits of some of these practices.”

With all these innovations — introduced in her farm over the years with the support of CIMMYT and the Ministry of Agriculture, Irrigation and Water Development of Malawi — Twaya reaped important economic and social benefits.

When Twaya rotates maize and pigeon pea, the maize stalks are healthy and the cobs are big, giving her higher yields. Passing-by neighbors will often exclaim ‘‘Is this your maize?’’ because they can tell it looks much more vigorous and healthier than what they see in other fields.

For the last season, Twaya harvested 15 bags of 50kg of maize from her demo plot, the equivalent of five tons per hectare. In addition to her pigeon pea and groundnut crops, she was able to feed her family well and earned enough to renovate her family home this year.

This new way of managing her fields has gained Twaya more respect and has improved her status in the community.

Smallholder wheat production can cut Africa’s costly grain imports

Written by Mike Listman on February 8, 2019. Posted in News.

International scientists are working with regional and national partners in sub-Saharan Africa to catalyze local wheat farming and help meet the rapidly rising regional demand for this crop.

The specialists are focusing on smallholder farmers in Rwanda and Zambia, offering them technical and institutional support, better links to markets, and the sharing of successful practices across regions and borders, as part of the project “Enhancing smallholder wheat productivity through sustainable intensification of wheat-based farming systems in Rwanda and Zambia.”

“Work started in 2016 and has included varietal selection, seed multiplication, and sharing of high-yielding, locally adapted, disease-resistant wheat varieties,” said Moti Jaleta, a socioeconomist at the International Maize and Wheat Improvement Center (CIMMYT) who leads the project. “Our knowledge and successes in smallholder wheat production and marketing will also be applicable in Madagascar, Mozambique, and Tanzania.”

Maize is by far the number-one food crop in sub-Saharan Africa but wheat consumption is increasing fast, driven in part by rapid urbanization and life-style changes. The region annually imports more than 15 million tons of wheat grain, worth some US$ 3.6 billion at current prices. Only Ethiopia, Kenya, and South Africa grow significant amounts of wheat and they are still net importers of the grain.

“Growing more wheat where it makes sense to do so can help safeguard food security for people who prefer wheat and reduce dependence on risky wheat grain markets,” Jaleta explained. “We’re working in areas where there’s biophysical potential for the crop in rain-fed farming, to increase domestic wheat production and productivity through use of improved varieties and cropping practices.”

In addition to the above, participants are supporting the region’s wheat production in diverse ways:

Recommendations to fine-tune smallholder wheat value chains and better serve diverse farmers.
Testing of yield-enhancing farming practices, such as bed-and-furrow systems that facilitate efficient sowing and better weed control.
Testing and promotion of small-scale mechanization, such as power tillers, to save labor and improve sowing and crop establishment.
Exploring use of hand-held light sensors to precisely calibrate nitrogen fertilizer dosages throughout the cropping season.

Innocent Habarurema, wheat breeder in the Rwanda Agriculture and Animal Resources Development Board (RAB), cited recent successes in the release of improved, disease resistant wheat varieties, as well as engaging smallholder farmers in seed multiplication and marketing to improve their access to quality seed of those varieties.

“The main challenge in wheat production is the short window of time between wheat seasons, which doesn’t allow complete drying of harvested plants for proper threshing,” Habarurema explained. “Suitable machinery to dry and thresh the wheat would remove the drudgery of hand threshing and improve the quality of the grain, so that it fetches better prices in markets.”

*Millers, like this one in Rwanda, play a key role in wheat value chains.*

Critical wheat diseases in Zambia include spot blotch, a leaf disease caused by the fungus Cochliobolus sativus, and head blight caused by Fusarium spp., which can leave carcinogenic toxins in the grain, according to Batiseba Tembo, wheat breeder at the Zambian Agricultural Research Institute (ZARI).

“Developing and disseminating varieties resistant to these diseases is a priority in the wheat breeding program at Mt. Makulu Agricultural Research Center,” said Tembo. “We’re also promoting appropriate mechanization for smallholder farmers, to improve wheat production and reduce the enormous drudgery of preparing the soil with hand hoes.”

Participants in the project, which runs to 2020, met at Musanze, in Rwanda’s Northern Province, during February 5-7 to review progress and plan remaining activities, which include more widespread sharing of seed, improved practices, and other useful outcomes.

“There was interest in trying smallholder winter wheat production under irrigation in Zambia to reduce the disease effects normally experienced in rainfed cropping,” said Jaleta, adding that the costs and benefits of irrigation, which is rarely used in the region, need to be assessed.

Project participants may also include in selection trials wheat varieties that have been bred to contain enhanced grain levels of zinc, a key micronutrient missing in the diets of many rural Africa households.

“The project will also push for the fast-track release and seed multiplication of the best varieties, to get them into farmers’ hands as quickly as possible,” Jaleta said.

In addition to CIMMYT, RAB, and ZARI, implementing partners include the Center for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA). Generous funding for the work comes from the International Fund for Agricultural Development (IFAD) and the CGIAR Research Program on Wheat.
