This little seed went to market

It’s not always easy to produce and sell new maize varieties in Malawi.

Seed companies often serve as the link between breeders and farmers, but numerous challenges — from lack of infrastructure to inconvenient finance systems — mean that the journey from the laboratory to the field is not always a smooth one.

In spite of this, the sector continues to grow, with established and up-and-coming seed companies all vying to carve their own niche in the country’s competitive maize seed market. To help bolster the industry, CIMMYT is working with around 15 seed companies in Malawi, providing them with early generation seed for CIMMYT-derived maize varieties, technical production training and marketing advice.

In a series of interviews, representatives from three of these companies share how they chose their flagship varieties and got them onto the market, and the CIMMYT support that helped them along the way.

The company started primarily because we wanted to help farmers — the issue of profits came later. The founders of Demeter Seeds saw a gap in the market for open-pollinated varieties (OPVs) and thought they could fill it. We’ve now migrated halfway into hybrids, but we still feel that we should serve both communities.

At the beginning we used to multiply and sell OPVs from CIMMYT, and we started doing our own multiplication here a few years ago. What I like about CIMMYT is they have been continuing to give us technical support. The breeding teams are our regular visitors. When they give us materials they come here, work with us, we go to the fields together. We’re so proud of this collaboration. Our whole company is based on CIMMYT germplasm since we don’t have our own breeding program to develop our own varieties.

How do you decide which varieties to work with?

When we were starting out, the decision of which varieties to work with was based on what CIMMYT recommended based on the data from on-farm trials. Most Malawian farmers use local maize varieties so it’s a good step for them to start using improved varieties – not necessarily hybrids.

Apart from the yields, what else do Malawian farmers look for? It has to be white and it has to be poundable or flint varieties with a hard endosperm. Of course, there are other attributes you have to worry about as well such as yield and drought tolerance. The seasons are changing, the rainfall period is becoming shorter so we’re looking for short-maturing materials in particular. If you have a variety that takes 90-100 days to mature, you’re OK, but if you choose one that takes 140-150, the farmer can be at risk of losing out because it doesn’t fit well into the growing season.

Having looked at those particular parameters we can decide on the variety we’re going to go for because this feeds into what our regular farmers want.

Is it easy to get farmers to buy those varieties, given that you know exactly what they’re looking for?

We’re not the only ones dealing with maize hybrids, so if you’re not aggressive enough in marketing you’ll not be able to survive.

You can’t just see that the demand is there and then put the product out. We have a marketing team within the company whose role is to market and advise the farmers. We try to listen to what’s happening on the ground, see how our varieties are performing and share results with the breeders. If you sell your seed you have to get feedback – whether it’s doing well or not.

But it can be difficult with the lack of infrastructure in Malawi. There are some places which are not accessible, so there are farmers who want your seed but you can’t reach them. Those farmers end up planting some local seed, which they might not have planted if they had access to improved varieties.

CIMMYT equals maize, so there’s very little we’d be doing without them. There has been collaboration and partnership since we started the seed business.

We got all the parent materials, expertise and production training from CIMMYT. We now even have our own CIMMYT-trained internal inspectors, who ensure that the seed that we produce meet quality standards that are required. When they were giving us the lines, they also helped us with production of the basic seed to start our maize production. Without CIMMYT, we wouldn’t be here.

You’re one of the few seed companies in Malawi producing vitamin A biofortified maize, which CIMMYT develops in partnership with HarvestPlus. How did you decide to work on that variety?

We selected the orange vitamin A maize firstly because of corporate social responsibility reasons. There is a developmental aspect to what we do, and we’re not just here for money. I think whatever we’re doing should also help the people that are buying from us. We knew that micronutrient deficiency is an issue in Malawi, so we hoped that the vitamin A biofortified maize could address some of the country’s malnutrition problems.

When the Government said it was looking at alternative ways of combating malnutrition, this was one of the proposed solutions and we thought we should be the first to do it. As of now, I think that of the 20-something lead seed businesses in Malawi, we’re one of only three producing this maize.

How challenging has it been to promote that variety?

Very, because the orange maize was not popular to begin with. In the first year, we had about 25 metric tons of seed and we didn’t even sell 10.

Yellow maize was brought in to feed people during a famine in the early 90s, so I think when people see orange maize now they are reminded of that hunger. There are still those negative associations. So we had to do some convincing, visiting farmers with HarvestPlus and telling them about the benefits.

But this is our third year and we don’t have any seed left — it’s all gone. Combined, the three companies involved in orange maize production had about 65 metric tons. But this year the demand has been around 1,050 metric tons. What we produced is not even one tenth of what is required.

Now that the orange maize has been popularized, we see demand increasing in the next five years as well. Apart from farmers, we’ve also had inquiries from people that want to use it for industrial purposes and are looking for very large quantities. Now we know, if people are looking for orange maize, we’ll be among the first to provide it.

Shane Phiri, Operations Manager at Global Seeds

I studied agribusiness management for my first degree and went into farming immediately after. Later I completed a Masters in Agronomy, but the moment I started talking to CIMMYT I knew that I was lacking knowledge on the technical side. Over the years I’ve attended a number of courses — maize technician courses and programs to help people in the seed industry learn about hybrids — thanks to CIMMYT. A large part of my knowledge has come from those trainings, visiting the research station in Harare and attending field days.

Global Seeds is known for its flagship product, MH34. Why did you decide to focus on that specific variety?

One of the main driving factors for us to go for MH34 was that it was not being produced by anyone else. This was a new variety that no other company had branded as their own yet, so it was a good opportunity for us to own it.

At the same time, I liked this variety because it had two lines from CIMMYT and one line that’s bred locally. It’s kind of a mix. I really liked that because it meant that it would be a bit of a challenge for anyone outside the country to produce it because they would not get that extra 25% from the Malawian line.

Did that also make it difficult for Global Seeds to produce?

It was not easy for us to get it on the market. It’s one of the stories I’m most proud of — to say we’re one of the few companies producing this variety — especially when I look back at the last three years and the work it took to get it to where we are.

We got the lines we needed from CIMMYT, but when we went to the local program to get that one last ingredient, we got less than 1.4 kilograms. Normally we would need at least 5 kilograms.

We knew we had to produce quickly to commercialize the variety, so we took 900 grams and started trying to increase the line under irrigation. Then the water supply ran out and we had to hire a water bowser. It was quite a journey but in the end we produced a handful of seed, and now the story is that this variety is flying off the shelves.

New crop varieties set to address drought, malnutrition

Written by Mary Donovan on April 27, 2020. Posted in In the media.

Test plot in Malawi includes drought-tolerant maize varieties developed by the International Maize and Wheat Improvement Center (CIMMYT); other maize varieties that are both drought-tolerant and high in vitamin A, developed by the HarvestPlus program and CIMMYT; and a high-iron bean variety developed by HarvestPlus and the International Center for Tropical Agriculture (CIAT).

Through thirty of these test plots established in the current growing season, the Clinton Development Initative, HarvestPlus and CIMMYT partners are reaching 30 000 farmers in 10 districts of Malawi.

Out of the classroom and into the field

Written by Emma Orchardson on April 23, 2020. Posted in Features.

When farmers in rural Kasungu, Malawi, are asked to list some of the challenges they face, much of what they say is to be expected. Crop pests, climate change, low soil fertility, and lack of improved seed and purchasing power — these are faced by smallholders across districts and the country as a whole.

But there is one surprising response. “Sometimes it’s difficult to get feedback from research centers on what does and doesn’t work,” says Maxwell Phiri.

Capacity building and knowledge transfer are key elements of agricultural development work, but there is often a gap between research, outreach and extension to farmers. New techniques and crop varieties tested at experimental stations can take a while to reach rural communities, who want solutions to the challenges they are facing in real time.

“But now it’s easier for us because the research is being done here.” Phiri points to the farmer field school in Msambafumu, a few hectares of communal land where 23 smallholders from the surrounding area meet regularly to learn about new technologies and farming techniques.

At the school they have been able to learn first-hand about improved and new agricultural practices and technologies. Following an introduction to climate-smart agriculture practices, they have moved on to agroforestry, learning about the benefits of intercropping drought-tolerant maize with pigeon peas and fruit trees. “We’ve even started practicing climate-smart agriculture in our own fields and planting agroforestry trees,” says Ntendeleza Mwale, a member of the field school in Msambafumu and chair of a network of 17 schools in the district. “Now everybody is growing fruit trees at home.”

“We didn’t know that potatoes, millet and sorghum could grow here, because we thought the soil wasn’t suitable, but the school has showed us what is possible,” explains Maxwell Phiri (first from left). “You learn a lot of things in a group that you might not learn on your own.” (Photo: Emma Orchardson/CIMMYT)

Back to school

A farmer field school is a group of 25-30 farmers, led by a master trainer, who come together to solve common challenges faced in their local area, such as soil degradation or poor water availability. Since 2014, the Government of Malawi has been using this innovative approach to help farmers learn about and improve their production systems through the KULIMA project. With support from a CGIAR consortium led by the International Potato Center (CIP), 15 schools have been established across the districts of Kasungu, Mulanje and Mzuzu, including master training hubs and outreach centers run by NGOs.

The overall objective is to increase agricultural productivity and diversification by upscaling climate-smart technologies,” explains Mathinda Sopo, a monitoring and evaluation specialist and project manager at the International Maize and Wheat Improvement Center (CIMMYT). “Master trainer candidates are selected in each district and then invited to sit down with researchers and identify their core production challenges. The plans are then developed collaboratively and based on agroecological zone.”

In February 2020, a new cohort of trainees arrived at the Lisasadizi Regional Training Center in Kasungu, where the Ministry of Agriculture coordinates trainings on four key topics — soil health, climate change, pests and diseases and nutrition — in collaboration with the UN Food and Agriculture Organization (FAO) and the CGIAR consortium, supported by the German development agency GIZ.

The 13-week residential course is mostly practical but does include some classroom-based study and a community outreach component. Guided by a facilitator — usually a researcher or extension worker — participants are encouraged to learn from their experiences as they conduct experiments in their own fields, make observations and evaluate results throughout the cropping season. Outside of the core curriculum, they are free to investigate additional topics of their own choice.

After completing the course, master trainers move back to their respective areas to help train facilitators, who are ultimately responsible for running the field schools with support from NGO extension staff.

“The CGIAR centers bring in technologies they want to promote like improved crop varieties, but there are ongoing evaluations throughout the process to respond to newly emerging challenges such as fall armyworm,” says Sopo. “There’s also a review at the end of each season to discuss lessons learned and knowledge gaps.”

CIMMYT, for example, is focusing on promoting drought-tolerant, quality protein maize (QPM), and provitamin A maize, as well as climate-smart agriculture practices. At Msambafumu, the group have been comparing five improved maize varieties with local ones. “So far we’ve seen that the new varieties have bigger yields and cob sizes,” says Mwale. “Varieties like Chitedze 2 QPM and MH43A are also early maturing and are more nutritious.”

Learning by doing

A few kilometers down the road, in Galika village, members of the Tiyese field school have been learning how to control a variety of pests and diseases. So far, they have been taught about different pesticides and the benefits of using inoculant on soya beans and ground nuts to improve soil fertility, and how to identify and mitigate disease in susceptible potato varieties. They have also been learning how to apply Aflasafe while crops are still in the field to reduce aflatoxins in maize and groundnuts.

But the most pressing challenge is fall armyworm, says Matolino Zimba, a member of the Tiyese field school. “We’ve been trying new methods for controlling it,” he explains. “Last year we planted mucuna beans in our banana orchard as a cover crop. Later we soaked mucuna leaves in water and poured the solution on the infested maize and noticed that the worms were dying.”

Zimba is satisfied with the learning methods at the field school. “This approach is better for us because we get to see the process, rather than just receiving an explanation.”

Emily Kaponda agrees. She first joined the group after noticing that participating farmers were getting higher yields by using new planting methods. “The school has a smaller plot of land than I do, but their bundles of maize were much larger,” she explains.

Since joining the field school, she has learned how to increase her yields, how to conserve moisture in the soil using zero-tillage farming and the importance of diversifying her family’s diets. “We’re learning how we can use cassava or sweet potato as a starch, instead of only using maize.”

Zimba and Kaponda are both excited to be trying out QPM and provitamin A maize varieties, as well as new varieties of cassava, orange-fleshed sweet potato, improved groundnuts, biofortified beans and bananas. Much like their peers at Msambafumu, they had not known that many of these could be grown in the area, and the group has already started planning to multiply planting materials to use in their own fields next year.

“These groups are really inspirational,” says Sopo. “Most members are already practicing things they’ve learned at their school and are getting positive results.”

Sopo is already seeing success stories from schools established one year ago, but collaboration will need to be sustained to ensure lasting progress. A new research initiative, Development-Smart Innovations through Research in Agriculture (DeSIRA), will help to maintain the positive feedback loop by investigating emerging issues raised during on-farm experiments. “We can take farmer observations from the study plots to DeSIRA for further research, and the outputs from that will complement KULIMA.”

KULIMA Promoting Farming in Malawi

Written by Emma Orchardson on April 22, 2020. Posted in Uncategorized.

KULIMA stands for ‘Kutukula Ulimi m’Malawi’, which means ‘promoting farming in Malawi’ in the country’s main local language, Chichewa. KULIMA aims to sustainably increase agricultural productivity and diversification of smallholder farmers based on market demand, while increasing income generation by farm enterprises and creating jobs through developing local value addition of raw agricultural products. It also seeks to stimulate better information supply on agricultural policy, investments and their outcomes to both government actors and the general public.

Within KULIMA Action, CGIAR Centers are working to make their expertise and technologies more easily available to more people. In coordination with GIZ and FAO, they provide guidance on the suitability of technologies and inputs in different agroecological zones in Malawi, successful agricultural practices, and the application of relevant innovations and technologies to address the issues affecting agricultural production systems in a holistic manner.

CIMMYT’s role within the project is to contribute towards increasing agricultural productivity and diversification through upscaling climate-smart agriculture technologies. To achieve this, CIMMYT supports production and utilization of drought tolerant and nutritious maize along with sustainable intensification practices that protect the soil and enhance soil fertility, commonly referred to as conservation agriculture. The focus is on creating demand for these technologies among smallholders by increasing awareness through farmer training, extension messaging and demonstrating the yield benefits of using drought tolerant versus unimproved non-drought tolerant varieties, and sustainable intensification practices versus conventional ones. CIMMYT is working in collaboration with NGOs and community-based organizations to train lead farmers and extension agents to reach out to smallholder farmers.

The project is financed under the 11th European Development Fund and is being implemented in ten districts of Chitipa, Chiradzulu, Karonga, Kasungu, Mzimba, Mulanje, Nkhata Bay, Nkhotakota, Salima and Thyolo.

Objectives

Increase agricultural productivity and diversify production in a participatory, sustainable and climate-change resilient manner
Establish agricultural value chains and create related income and employment opportunities
Strengthen agricultural sector governance

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).

Study calls for better understanding of fertilizer prices faced by African smallholder farmers

Written by Rodrigo Ordóñez on January 15, 2020. Posted in News. 1 Comment on Study calls for better understanding of fertilizer prices faced by African smallholder farmers

Crop yields in sub-Saharan Africa are generally low. This is in large part because of low fertilizer use. A recent study of six countries in sub-Saharan Africa showed that just 35% of farmers applied fertilizer. Some possible reasons for this could be that farmers may be unaware of the efficacy of fertilizer use; or have degraded soils that do not respond to fertilizer; they may not have the cash to purchase it; or because unpredictable rainfall makes such investments risky. It may also be because local fertilizer prices make their use insufficiently profitable for many farmers.

To better understand the potential fertilizer demand in a particular location, it is important to know how crops respond to fertilizer under local conditions, but it is critical to understand crop responses in terms of economic returns. This requires information about local market prices of fertilizers and other inputs, as well as the prices that a farmer could receive from selling the crop.

While national-level fertilizer prices may be available, it is necessary to consider the extent to which prices vary within countries, reflecting transportation costs and other factors. In the absence of such data, analysis of household-level behaviors requires assumptions about the prices smallholder farmers face — assumptions which may not be valid. For example, evaluations of the returns to production technologies settings have often assumed spatially invariant input and output prices or, in other words, that all farmers in a country face the same set of prices. This is at odds with what we know about economic remoteness and the highly variable market access conditions under which African smallholders operate.

An obstacle to using empirical data on sub-national disparities in fertilizer prices is the scarcity of such data. A new study focused on the spatial discrepancies in fertilizer prices. The study compiled local market urea price in eighteen countries in sub-Saharan Africa for the period between 2010-2018 and used spatial interpolation models — using points with known values to approximate values at other unknown points — to predict local prices at locations for which no empirical data was available. It was conducted by scientists at University of California, Davis, the International Maize and Wheat Improvement Center (CIMMYT) and the International Food Policy Research Institute (IFPRI). The authors note that this is the first major attempt to systematically describe the spatial variability of fertilizer prices within the target countries and test the ability to estimate the price at unsampled locations.

Predicted relative urea price (local price divided by the observed median national price) for areas with crop land in eight East African countries.

“Our study uncovers considerable spatial variation in fertilizer prices within African countries and gives a much more accurate representation of the economic realities faced by African smallholders than the picture suggested by using national average prices,” said Camila Bonilla Cedrez, PhD Candidate at University of California, Davis. “We show that in many countries, this variation can be predicted for unsampled locations by fitting models of prices as a function of longitude, latitude, and additional predictor variables that capture aspects of market access, demand, and environmental conditions.”

Urea prices were generally found to be more expensive in remote areas or away from large urban centers, ports of entry or blending facilities. There were some exceptions, though. In Benin, Ghana and Nigeria, prices went down when moving away from the coast, with the possible explanation being market prices in areas with higher demand are lower. In other locations, imports of fertilizer from neighboring countries with lower prices may be affecting prices in another country or region, much like political influence. Politically, well-connected villages can receive more input subsidies compared to the less connected ones.

“The performance of our price estimation methods and the simplicity of our approach suggest that large scale price mapping for rural areas is a cost-effective way to provide more useful price information for guiding policy, targeting interventions, and for enabling more realistic applied microeconomic research. For example, local price estimates could be incorporated into household-survey-based analysis of fertilizer adoption,” explained Jordan Chamberlin, CIMMYT spatial economist. “In addition, such predictive ‘price maps’ can be incorporated into targeting and planning frameworks for agricultural investments. For example, to target technology promotion efforts to the areas where those technologies are most likely to be profitable.”

Predicted relative urea price (local price divided by the observed median national price) for areas with crop land in nine West African countries.

“The evidence we have compiled in this paper suggests that, while investments in more comprehensive and spatially representative price data collection would be very useful, we may utilize spatial price prediction models to extend the value of existing data to better reflect local price variation through interpolation,” explained Robert J. Hijmans, professor at University of California, Davis. “Even if imperfect, such estimates almost certainly better reflect farmers’ economic realities than assumptions of spatially constant prices within a given country. We propose that spatial price estimation methods such as the ones we employ here serve for better approximating heterogeneous economic market landscapes.”

This study has illustrated new ways for incorporating spatial variation in prices into efforts to understand the profitability of agricultural technologies across rural areas in sub-Saharan Africa. The authors suggest that an important avenue for future empirical work would be to evaluate the extent to which the subnational price variation documented is a useful explanatory factor for observed variation in smallholder fertilizer use in sub-Saharan Africa, after controlling for local agronomic responses and output prices. One way to do that may be to integrate input and output price predictions into spatial crop models, and then evaluate the degree to which modeled fertilizer use profitability predicts observed fertilizer use rates across different locations.

Malawi farmers nurture soil grow incomes with conservation agriculture

Written by Mary Donovan on December 14, 2019. Posted in In the media.

The International Maize and Wheat Improvement Center (CIMMYT) introduced farmers Kassim Massi and Joyce Makawa to conservation agriculture, along with five other families in their community.

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.

Join us on this visual journey across Ethiopia, Kenya, Malawi and Zimbabwe, where you will meet farmers who demonstrate every day what it means to be RURAL: Resilient, United, Reaping benefits, Adopter and Learner.

These women have adopted climate-smart practices in their production systems to ensure optimal yields while learning about drought-tolerant varieties of maize to counter the harsh effects of dry spells, heat stress, pests and diseases. These rural women are exemplary leaders in their communities, as evidenced by their successful farming practices and the food and income they secure for their families.

Farming families in southern Africa are confronted with the adverse effects of climate change, particularly in Malawi, Mozambique and Zimbabwe. A report by FEWS NET indicates negative impacts like declining yields, increase in grain prices during peak lean seasons and widespread food insecurity. However, Lughano Mwangonde from Malula, southern Malawi, has been practicing climate-smart agriculture since 2004 through a CIMMYT project, which has improved the food security of her family. In the midst of increasing climate variability, Lughano is cushioned against the harsh effects of droughts and heavy downpours through the practices she adopted. For example, she uses crop rotation of maize and legumes, like cowpea and pigeon pea.

Climate change affects men and women differently. Rural women farmers tend to be more susceptible to drought and the additional labor associated with household tasks. As such, building resilience against climate change is critical. For Sequare Regassa, in Ethiopia’s Oromia region, this means shifting to drought-tolerant maize varieties such as BH661, which have better performance and increased yield, even under heat and other stress conditions.

Sequare Regassa is the family’s breadwinner, looking after her four children and working closely with her extended family on their 8-hectare farm in Ethiopia’s Oromia region. “Getting a good maize harvest every year, even when it does not rain much, is important for my family’s welfare,” she says. Although her children are now grown and living with their own families, the family farm unites them all in producing adequate grain to feed themselves. Read more about how Regassa and other farmers are weatherproofing their livelihoods.

Rural women farmers are taking up improved drought-tolerant and high yielding varieties with early maturity thanks to participatory maize varietal selection. “If I am able to harvest in three and a half months or less, compared to four months or more for other varieties, I can sell some grain to neighbors still awaiting their harvest who want to feed their families,” says Tabitha Kamau. She is a smallholder farmer in Machakos County, Kenya, who plants drought-tolerant maize on her plot. Read about how farmers in her area are choosing the varieties that work best for them.

Rose Aufi explains how her family of seven children and three grandchildren are food-secure thanks to the climate-smart agriculture techniques she practices on her farm in Matandika, southern Malawi. She and her husband have obtained a good harvest since they started participating in a CIMMYT project and adopted climate-smart agricultural practices. Aufi says technologies such as mulching and crop rotation are there to simplify the workload in the field.

Dolly Muatha, a 49-year-old farmer with four children in Kenya’s Makueni County, has been growing SAWA drought-tolerant maize for three years. She has witnessed the performance of this variety in her demo plot. “It matures early and yields two to three beautiful cobs per plant” she says.

Ruth Kanini Somba adopted SAWA maize in 2017 after seeing a demonstration plot at Dolly Muatha’s farm. She points out that SAWA performs better than other varieties because of its early maturity and resistance to grey leaf spot and weevils. The drought-tolerant attribute of the SAWA maize also makes the maize crop cope well when rainfall is erratic.

Improved agricultural techniques, such as optimum spacing, enables farmers such as Agnes Nthambi to get better crops. This farmer from Kenya’s Machakos County hosted a demonstration plot she and other farmers in her area were able to learn new growing techniques. “On this trial, I learned that spacing was about two times shorter than we are generally used to. Even with the more constricted spacing, the maize has performed much better than what we are used to seeing,” Nthambi explained.

Pulses, cobs and a healthy soil prove the success of a rural innovator

Written by Shiela Chikulo on October 14, 2019. Posted in Features. 2 Comments on Pulses, cobs and a healthy soil prove the success of a rural innovator

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.
