Fall armyworm devastates crops in sub-Saharan Africa: A quick and coordinated regional response is required

Written by on June 2, 2017. Posted in News.

The recent appearance of the fall armyworm, an insect-pest that causes damage to more than 80 crop species in 14 countries in sub-Saharan Africa, poses a serious challenge and significant risk to the region’s food security.

In a recent interview, B.M. Prasanna, director of the Global Maize Program at International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR Research Program on MAIZE, who is working at the forefront of CGIAR’s response, highlights the potential impact of the pest and how CGIAR researchers are contributing to a quick and coordinated response across the region.

Q: What is the fall armyworm and why is it so destructive?

The fall armyworm (Spodoptera frugiperda) is an insect-pest which causes major damage to more than 80 crop species, including economically important crops, such as maize, rice, sorghum, wheat, sugarcane, several other vegetable crops and cotton.

It was first officially reported in Nigeria in early 2016 and has been officially confirmed in 11 and suspected in at least 14 other African countries, as of April 2017.

Q: What are the potential impacts of the pest in sub-Saharan Africa?

The fall armyworm poses a serious challenge and a significant, ongoing risk to Africa’s food security.

The pest’s ability to feed on a range of crop species means that smallholder farming systems in Africa, which are based on intercropping, are particularly vulnerable. Also, the rapid damage and migratory capacity of the pest, combined with its capacity to reproduce quickly in the right environmental conditions and its ability to rapidly evolve resistance to synthetic pesticides increase the region’s vulnerability.

In sub-Saharan Africa, where fall armyworm is currently devastating maize crops, estimates indicate 13.5 million tons of maize valued at $3 billion are at risk in 2017-2018, which is equivalent to over 20 percent of total production for the region (based on data from CABI, April 2017).

Q: What are the key challenges that countries in sub-Saharan Africa will face?

There is no doubt that smallholder farmers, particularly maize farmers, in sub-Saharan Africa will face a significant and ongoing risk from the fall armyworm. In particular, resource-poor smallholders will be severely affected due to their inability to control the pest using synthetic pesticides, currently the only way to effectively respond, which are very costly.

Q: What are three ways that countries in sub-Saharan African can strengthen resilience of food and agricultural systems to the potential effects of Fall Armyworm?

Working groups need to be established quickly to develop and implement strategies to respond to the issue. In particular, we need to develop a comprehensive, regional response centered on: Monitoring and early warning; Social and economic assessments of impacts, and forecasting; Integrated Pest Management (IPM); Development and dissemination of low-cost, effective and sustainable solutions and development of appropriate regulatory tools and policies to support the response.
As this process unfolds, gaps, challenges and successes will need to be documented to inform capacity-building needs with a focus on understanding the capacity of individual countries to respond. While fall armyworm outbreaks across Africa is an emergency situation, it should also be an opportunity to review and understand regional food production and food security issues and as an opportunity to improve on systematic approaches to build capacity to prevent and respond to future threats of transboundary pests and pathogens in Africa.
Strong coordination across different levels of government is required: “political coordination” (among the local governments, NPPOs, and sub-regional organizations), and “technical coordination” (fast-tracked testing and deployment of relevant technologies).

Q: What role do CIMMYT and CGIAR have in building capacity in the region’s ability to respond to Fall Armyworm?

CGIAR institutions, including CIMMYT and the International Institute of Tropical Agriculture (IITA), have significant strengths in building the region’s ability to respond to trans-boundary pathogens (e.g., previous examples include Maize Lethal Necrosis, wheat rust and insect-pests, such as fall armyworm.

Specific examples of CGIAR/CIMMYT expertise that will be important in the fall armyworm response include:

Development and dissemination of crowd-source based tools and digital surveillance systems and analysis of the data collected across countries for a strong monitoring and early warning system.
Systematic and large-scale assessment of the present and potential socio-economic impact of fall armyworm in Africa, and the development of forecasting tools to understand potential losses
Review of the efficacy of different fall armyworm management options (learning from experiences of the United States, Brazil and Mexico), and adapting this information to the African context
Determining the efficacy of cultural control options against fall armyworm, including early versus late planting of crops like maize, handpicking, soil and habitat management, crop hygiene, etc.
Evaluating the impacts on-going integrated pest management (IPM) initiatives and the impacts of the fall armyworm invasion on the effectiveness of these interventions
Developing and implementing appropriate insect resistance monitoring and management strategy in fall armyworm affected countries
Analysis of the effects of conservation agriculture on fall armyworm management and the influence of fall armyworm incidence on diverse cropping systems
Testing and introgression of conventionally-derived resistance (from identified CIMMYT and U.S. Department of Agriculture-Agricultural Research Service [USDA-ARS] germplasm sources) into Africa-adapted maize germplasm, followed by fast-tracked varietal release, seed scale-up and delivery of improved maize hybrids/varieties through public-private partnerships (e.g., MLN is a great example of this).
Developing a “Fall Armyworm Information Portal”, similar to the MLN Information Portal and Wheat Rust Tracker (led by CIMMYT), as a one-stop portal for relevant information.

Q: CIMMYT recently co-hosted an emergency meeting on the strategy for effective management of fall armyworm in Africa. What were the key outcomes and next steps for the response to this issue?

The emergency meeting was an opportunity to assess the present and potential damage due to fall armyworm and to devise a holistic control strategy.

CIMMYT, Alliance for a Green Revolution in Africa (AGRA) and the U.N. Food and Agriculture Organization (FAO) jointly hosted a Stakeholders Consultation Meeting in Nairobi, Kenya (April 27-28, 2017). About 150 experts and stakeholders from 24 countries in Africa, and five outside Africa (Italy, Spain, Switzerland, Britain and the United States) participated, with participants from government, national plant protection agency, national agricultural research systems in Africa, as well as scientists from international agricultural research organizations, and representatives of service providers, non-governmental organizations, development partners, donor agencies and the media.

Discussions covered the present status of the pest in Africa as well as contingency plans to manage the pest, assessment of current control options being used. Experts from the U.S. and U.K. provided expertise and insight on the response to fall armyworm in the U.S. and Brazil.

Action points and recommendations on four key areas were developed to ensure an effective, coordinated response:

Contingency planning and awareness generation;
Fall armyworm monitoring and early warning;
Socio-economic impact assessments and modeling of potential losses;
Development and Dissemination of fall armyworm management options;
Coordination of Institutional Interventions for fall armyworm management in Africa.

FAO is expected to convene a regional workshop in early June to engage and coordinate with relevant regional organizations who will be involved in the response.

CIMMYT and CGIAR have responded and will continue to address the issue over the following months.

Three major commercial maize seed exporting countries in southern Africa found free from maize lethal necrosis

NAIROBI, Kenya (CIMMYT) – Three major commercial maize-growing and seed exporting countries in southern Africa were found to be so far free from the deadly maize lethal necrosis (MLN) disease. MLN surveillance efforts undertaken by national plant protection organizations (NPPOs) in Malawi, Zambia and Zimbabwe in 2016 have so far revealed no incidence of MLN, including the most important causative agent, maize chlorotic mottle virus (MCMV).

The three countries export an estimated 7,000 metric tons of maize seed to Angola, Botswana, Democratic Republic of Congo, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Swaziland and Tanzania for commercial cultivation by millions of smallholder farmers whose households rely on maize as a staple food.

MLN surveys were conducted as part of ongoing efforts through a project on MLN Diagnostics and Management, funded by U.S. Department for International Development (USAID) East Africa Mission, to strengthen the capacity of NPPOs on surveillance and diagnostics. A total of 12 officers were equipped with knowledge on modern sampling and diagnostics techniques to test plants and seed lots for MLN causing viruses; this was done through a training workshop held in Harare, Zimbabwe on March 3 and 4, 2016 facilitated by scientists working with the International Maize and Wheat Improvement Center (CIMMYT).

The NPPO teams from Malawi, Zambia and Zimbabwe then undertook surveys of farmers’ and commercial maize seed production fields, including testing (through MCMV immunostrips) for possible presence of the virus.

“When CIMMYT called the first stakeholders awareness meeting we realised we needed to do this surveillance as soon as possible to ascertain MLN status in the country – and so the training was very important and extremely useful,” said Maimouna Abass, a plant health inspector at Zambia Agriculture Research Institute (ZARI). “The fact that we went to the field and successfully conducted the surveys using the MLN diagnostics and sampling techniques learnt was great.”

Abass and three colleagues who participated in the training, trained 10 other inspectors who took part in the surveillance work.

The results from farmers’ fields, commercial seed production fields and agri-seed dealers, showed negative results for the presence of MCMV and MLN. The MLN surveillance techniques and protocols used across all the three countries were similar, making it possible to effectively compare the results.

“The harmonization of the protocols, across the teams from Malawi and Zambia, was important for me, since this meant that the three countries were able to do the same surveillance using the same protocols and applying the same design across all the countries,” said Nhamo Mudada, chief research officer from the Plant Quarantine Station in Zimbabwe.

Although the MLN disease has not been detected in the southern Africa region, the risk of incidence still remains high through various means, including insect vectors, contaminated seed, and cross-border grain transfers. Therefore, continued caution and stringent surveillance, monitoring and diagnostic measures are required to prevent the possible incidence and spread of MLN into the non-endemic countries.

Further surveillance work will be conducted in 2017, so that each team can cover other targeted areas within their respective countries. MLN surveillance using harmonized protocols will also be undertaken in the MLN-endemic countries, namely Ethiopia, Kenya, Rwanda, Tanzania and Uganda. Through systematic surveillance efforts, NPPOs, seed companies and policymakers can clearly understand the prevalence of MLN in specific areas in an endemic country for targeted management. Also, seed companies will be able to target production of commercial seed in MLN-free areas.

As this work progresses, B. M. Prasanna, director of the CGIAR Research Program on MAIZE and CIMMYT’s Global Maize Program as well as Leader for the MLN Diagnostics and Management Project, emphasized the need to intensively deploy MLN-tolerant and resistant varieties, not only in the MLN-endemic countries in eastern Africa, but also in the non-endemic countries in sub-Saharan Africa.

“We have about 22 new, high-yielding, MLN-tolerant or resistant hybridsthat are presently under national performance trials in Kenya, Tanzania and Uganda. We actively encourage seed companies operating in southern Africa to take up promising pre-commercial hybrids with MLN tolerance or resistance from CIMMYT, for release, scale up and deployment to the farmers,” Prasanna said. “Diagnostics and surveillance have to go hand in hand with deployment of new improved varieties that can effectively respond to the MLN challenge.”

In the East African countries of Kenya, Tanzania and Uganda, seed companies have already released MLN-tolerant varieties. While one hybrid is already being commercialized in Uganda, three more are expected to reach farmers in Kenya and Tanzania from 2017.

“There is also now a very urgent need to deploy MLN resistant varieties in Rwanda and Ethiopia. We need to convey this message to the government and seed companies and work closely to get the seed of MLN resistant varieties to the farmers as soon as possible,” Prasanna added.

The MLN diagnostics and management project, which is funded by the U.S. Department for International Development (USAID), supports work aimed at preventing the spread of MCMV from MLN-endemic to non-endemic areas in sub-Saharan Africa. USAID also supports the commercial seed sector and phytosanitary systems in targeted countries (Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe), in the production of MCMV-free commercial seed, and promotes the use of clean hybrid seed by the farmers.

Building Zambia’s drought-tolerant maize business

Written by on July 12, 2016. Posted in News.

LUSAKA, Zambia — For 62 year old Margaret Chisangano, life had been full of hard work. She used to rise early morning and carry out her tasks on her small farm – mainly growing maize without access to irrigation.

Chisangano lives in a rural village in Chongwe District of Zambia’s Lusaka Province. Average temperatures and erratic rainfalls in the region have been increasing, making it a daily challenge to feed her five grandchildren.

Margaret Chisangano harvested and sold 25 tons of drought tolerant maize from her 7-hectare plot in 2015, from 7.5 tons the previous season. This year, she expects to double her yields. With the extra income, Chisangano can feed her entire family and buy clothes, medicine and school supplies for her grandchildren.

This year, she expects to double her yields. With the extra income, Chisangano can feed her entire family and buy clothes, medicine and school supplies for her grandchildren.

“Due to the harsh climate, farming was like gambling with nature,” she says. “Relying on the government’s relief food was only a temporary solution that did not solve our larger issues.”

Many farmers like Chisangano in rural Zambia are struggling to maintain their harvests while climate change makes it harder every year to produce a successful harvest. In the face of the drought crippling southern Africa, drought tolerant maize can reduce risks for farmers and allow for more consistent crop production in the face of climate variability. This enables farmers to allocate more land to higher-value crops with better economic returns, improving food security and incomes.

CIMMYT is working to improve access to good-quality maize through production and deployment of affordable and improved drought-tolerant, stress-resilient and high-yielding maize varieties for smallholder farmers throughout Zambia. Kamano Seed Company is one of six seed companies that CIMMYT partners with to improve maize production and marketing for small-scale farmers. The company provides drought-tolerant maize seeds, fertilizers and training to help farmers commercialize their production.

The company also focuses on increasing productivity and market access for farmers to drought-tolerant maize seed, and trains farmers on how to properly apply fertilizer that can help double or quadruple their maize yields. Many farmers Kamano works with are growing maize commercially for the first time.

Chisangano was one of the first female farmers to join the contract farming project. Like many rural women in Zambia, she had little access to economic opportunities outside of subsistence farming.

To invest in developing agribusinesses, Kamano Seed Company is establishing links with banks to access loans to pay the farmers for their maize seed to avoid side marketing. The smallholder farmers also receive training in business skills, including record keeping, and the basics of contract farming.

“This new knowledge to look at farming as a business, and the training in record keeping, has changed my farming enterprise,” said Chisangano. “Before, we did not treat farming as a business, and as a result we couldn’t earn any profits.”

Investing in agribusinesses development allows farm families to have a more consistent source of food and income throughout any given year, according to Nokutula Zimba, Kamano Seed Company senior marketing and sales officer. “In the long term, these farming activities help communities withstand future food crises and increase income-earning opportunities.”

In addition to on-the-ground development, CIMMYT provides input for greater seed policy reforms in southern Africa to facilitate easy seed movement across borders, and to make the variety release and registration processes more efficient.

Led by the International Maize and Wheat Improvement Center, and implemented through in-country public and private partnerships, the Drought-Tolerant Maize for Africa Seed Scaling Project is supported by the United States Agency for International Development and emphasizes the scaling up and scaling out of drought tolerant maize seed and uptake by smallholder farmers. The project aims to produce close to 12,000 metric tons of certified seed for use by approximately 2.5 million people in six countries in eastern and southern Africa by the end of 2020.

Drought-tolerant maize a boon to farmers in Zambia hit by El Niño

Written by on July 8, 2016. Posted in Features.

“With consistently impressive harvests thanks to DT maize varieties, I’m always assured that my family will have enough food, and I can earn a decent income from selling some grain," said Piri, a smallholder farmer in Petauke District, Zambia.

NAIROBI, Kenya (CIMMYT) – Drought-related challenges in Africa call for proactive interventions rather than reactive ones. Every so often a drought hits, jolting the development community into action, and leading to the delivery of food aid to millions of people facing starvation — beneficial efforts in the short term, but futile for achieving lasting change.

The need for sustainable strategies that guarantee households remain food secure even when natural disasters strike is widely recognized throughout the international agriculture-for-development community and supported by the U.N. Sustainable Development Goals.

CIMMYT plays a significant role in supporting these efforts in Africa by developing drought-tolerant (DT) maize and wheat seeds that give smallholder farmers long-term solutions to recurring drought. Drought-tolerant maize varieties are scaled out through the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project.

The drought that has gripped much of southern Africa during the 2015/2016 agricultural season due to a disruptive El Niño went on record as the worst in 50 years, affecting an estimated 40 million people. While Malawi, Mozambique and Zimbabwe declared the drought a national disaster, Zambia managed to meet its national maize production average, thanks largely to smallholder farmers, who plant roughly 51% of the total cultivated land in the country.

As in most countries in sub-Saharan Africa, in Zambia rain performance determines crop performance; however, despite the late and erratic rains in 2015-2016, smallholder farmers have reason to smile. This good fortune is evident in Petauke district in Zambia’s Eastern Province, roughly 400 kilometers (250 miles) from the capital Lusaka, where granaries are packed to the brim thanks to the bountiful maize harvest.

At the recommendation of a fellow farmer, 36-year-old Miriam Piri, a mother of six, started planting a DT maize variety in 2013 under the Drought Tolerant Maize for Africa project. Realizing she was getting a bigger yield from the DT variety than a local one, Miriam continued to plant it.

“I grow DT maize variety PAN53 on roughly two hectares of land, and for the last three years my yields have been impressive,” said Piri. “I was a little anxious about my harvest because of poor rains, but I got the highest yield ever in three years!”

For its ability to thrive in both dry and wet conditions, and in low- to mid-altitude regions, PAN 53 is easily one of the most popular DT varieties in Zambia. In addition to its impressive yields, farmers enjoy the hybrid’s flint-type grain, which makes for easier and quicker pounding, and its densely packed cobs, which add up to more grain. PAN 53 is also resistant to leaf blight, gray leaf spot and ear rot.

Every season Piri plants 40 kilograms (90 pounds) of PAN 53, from which she harvested 45 50-kg bags in 2013. This was followed by yields of 35, 50 and 70 bags in 2014, 2015 and 2016, respectively.

“Going forward, I will plant both local and drought-tolerant varieties for my family’s consumption and sale, respectively. I sell the DT maize exclusively to the government and wholesalers, so I get a fair price. With this income, I can focus on other projects,” Mwanza said. Photo: Kelah Kaimenyi/CIMMYT

PAN 53 is produced and distributed by Pannar, the largest independent seed group in South Africa, and one of the largest seed suppliers in sub-Saharan Africa. Pannar has the third largest market share in Zambia.

According to the Famine Early Warning Systems Network, Zambia is expected to substantially exceed national requirements this consumption year given its maize production of 2.87 million metric tons (MT) in 2016, combined with an estimated maize carryover stock of approximately 667,500 MT.

A few doors down from Piri is 66-year-old Piri Mwanza, who also plants DT maize. For Mwanza, planting a DT maize hybrid at the onset of this year’s drought was a risk he was willing to take. Throughout 44 years as a farmer, he knew only the local maize variety until an agro-dealer convinced him to try something new. He invested $37 to buy 20 kilograms of DT maize seed and fertilizer for his one-hectare farm. Despite poor rains, he harvested 55 bags of maize compared to 40 bags the previous year with the local variety.

“I’m impressed with my harvest, and will continue investing in DT maize even when the season gets better and the rains normalize,” said Mwanza.

Planting drought-tolerant varieties has proven to be a sustainable strategy for improving food security. Continuous efforts by CIMMYT’s DTMASS project to promote the benefits of improved varieties will go a long way toward convincing smallholder farmers to adopt them.

Smallholders in Rwanda and Zambia to enhance wheat productivity through new project

Written by on June 28, 2016. Posted in Features.

KIGALI, Rwanda (CIMMYT) – The recent designation of wheat as a strategic crop for Africa by the African Union in 2013 reflects the rising importance of wheat production on the continent. Since then, efforts have intensified to incorporate wheat production into existing farm systems and to help smallholders grow it to meet rising demand and reduce the economic impact of the high cost of imports.

The International Maize and Wheat Improvement Center (CIMMYT) is contributing to these efforts through a project launched this month in Kigali, Rwanda. The four-year Enhancing Smallholder Wheat Productivity through Sustainable Intensification of Wheat-based Farming Systems in Rwanda and Zambia (SWPSI) project aims to enhance the potential of wheat produced by smallholder farmers to bolster food security.

“Given the increasing opportunities in wheat research, CIMMYT is happy to work with partners to help farmers adopt improved technologies, establish innovation platforms and strengthen wheat value chains in the two countries,” said Bekele Abeyo, Ethiopia country representative and wheat breeder at CIMMYT.

Zambia and Rwanda rank 46th and 59^th respectively in the list of wheat-producing nations, topped by China. Production in Zambia, where wheat grows on more than 40,000 hectares (99,000 acres), is largely undertaken by medium and largescale commercial operations in irrigated conditions with very little smallholder production. On the other hand, in Rwanda wheat is grown on about 35,000 hectares in rainfed conditions mainly by smallholder farmers.

“The contrast between the two countries will help generate wider lessons on variations and give an opportunity to test whether wheat is still a potential crop to produce profitably under smallholder systems,” said Moti Jaleta, CIMMYT SWPSI project leader.

The new project will target 4,000 smallholder farmers in the two countries, with a focus on increasing wheat productivity from the current 2.1 tons per hectare to an average of 4.5 tons per hectare.

Smallholders will also benefit from improved technologies, which include rust-resistant and high-yielding wheat varieties, such good agronomic practices as row planting, precise fertilizer application, plant density and planting dates. Additionally, threshing technologies to enhance grain quality and efforts to link farmers with established traders and millers to help them secure markets for their wheat surplus will be undertaken.

The project mandate includes a scoping study on the potential for smallholder wheat production in Madagascar, Mozambique and Tanzania.

Funded by the International Fund for Agricultural Development and the consortium of agricultural researchers, the CGIAR Research Program on WHEAT, SWPSI will be implemented under the leadership of CIMMYT in close collaboration with the Center for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA), the Rwanda Agriculture Board and the Zambia Agricultural Research Institute.

Speaking during the launch, the acting executive director of CCARDESA, Simon Mwale, noted the rising demand for wheat, particularly in southern Africa, which also has a very conducive climate for wheat farming.

“Inclusion of Rwanda in the project is a unique opportunity for CCARDESA, and it will facilitate strong collaboration and new learning opportunities, being a new country to be covered by CCARDESA,” he said.

Experts hope SWPSI will contribute to the broader focus of the strategy to promote African wheat production and markets.

Some 30 key stakeholders met at a side event organized by CIMMYT at the recent 7th Africa Agricultural Science Week (AASW) to discuss how best to implement the region’s wheat strategy. The AASW and FARA General Assembly is the principal forum for all stakeholders in African agriculture science, technology and innovation to share solutions to some of the most pressing challenges the continent faces. CIMMYT’s SWPSI project is key to supporting the wheat for Africa strategy whose goal is to increase agricultural productivity and food security throughout the region.

New Publications: Land availability and smallholder development in Zambia

EL BATAN, Mexico — Large surface area and low population density make Zambia one of the most land abundant countries in the world.

However, despite this abundancy new data shows that land access is of mounting concern for smallholders. 54 percent of Zambia’s land is under customary tenure, far less than the 94 percent often utilized in land policy documents, according to a new study. Customary land tenure refers to the systems that most rural African communities operate to express and order ownership, possession, and access, and to regulate use and transfer. Unlike introduced landholding regimes, the norms of customary tenure derive from and are sustained by the community itself rather than the state or state law.

Of this available land, most populations are clustered in just 5 percent that has reasonably good market access conditions. These areas are often located in regions with high levels of rainfall variability due to historical infrastructure investments. In addition, these regions are witnessing a rapid increase in land commodification, land alienation and declining fallow rates.

The study concludes that land policy alone is not sufficient to cope with the mounting land constraints experienced by the majority of rural people in Zambia. Investments in infrastructure and services to improve market access conditions and climate change adaption capacity in Zambia’s remaining customary land is a necessity. Land and economic development policies must be attentive to changing dynamics in customary land areas in order to ensure the future viability of the smallholder farming sector.

Building a sustainable future: A history of conservation agriculture in southern Africa

Written by on June 23, 2016. Posted in News.

This story is one of a series of features written during CIMMYT’s 50th anniversary year to highlight significant advancements in maize and wheat research between 1966 and 2016.

HARARE, Zimbabwe (CIMMYT) — When practiced unsustainably, agriculture has led to environmental degradation and famine, which have plagued civilizations through the centuries. Innovations such as irrigation or the plow (since circa 6,000 and 3,000 BC) increased productivity, but often deteriorated long-term soil fertility through erosion and other forms of degradation.

We are now facing historically unprecedented challenges to food security. We must increase food production by 70 percent to feed nine billion people by 2050, without damaging our finite and often already degraded natural resource base. In addition, farmers face more frequent drought and water scarcity, which makes it increasingly difficult to grow crops, and extreme weather events such as the 2015-2016 El Niño, which has already caused large-scale crop failures and soaring maize prices in southern Africa.

Conservation agriculture (CA) practices based on the principles of minimal soil disturbance, permanent soil cover and crop rotation are helping farmers combat growing environmental challenges by maintaining and boosting yields, while protecting the environment and increasing profits for smallholders globally. When CA practices are coupled with water-use efficient and drought tolerant varieties, the benefits are even greater.

Drought is increasingly common in Malawi, leaving an estimated three million people in need of urgent humanitarian food assistance this year alone. However, a fortunate few will escape hunger, including more than 400 farmers and their families in Balaka, southern Malawi, who have been practicing CA over the last 12 years. "Few farmers have livestock in Balaka, so crop residues can be kept on the fields instead of feeding them to cattle," according to Thierfelder, who says Malawi presents a good case for conservation agriculture. CIMMYT and its strategic development partner Total LandCare have helped more than 65,000 farmers adopt CA systems throughout the entire country.

“CA approaches can mean the difference between farmers being able to feed their families or having to starve,” says Christian Thierfelder, senior cropping systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT), regarding the recent El Niño – the strongest on record – in southern Africa. To date, approximately 10 million people in southern Africa are dependent on food aid and an estimated 50 million people are projected to be affected, pushing them to the brink of starvation.

Sustainable intensification of agricultural systems and practices such as CA have become a necessity for farmers in Africa, where a combination of climate change and unsustainable agricultural practices are undermining land and water resources. This, coupled with an exploding population, makes increasing productivity while conserving the environment absolutely urgent.

Based on its experience in Latin America, which began in the early 1990s, CIMMYT started its first CA project in Africa in 2004, targeting Malawi, Mozambique, Tanzania, Zambia and Zimbabwe. This initial work focused on understanding CA systems in the context of farmers and their environmental conditions and was funded by the German government and the International Fund for Agriculture Development. Its aim was to facilitate the adoption of CA systems by smallholder farmers. This culminated in the establishment in 2009 of a large PAN-African project on Sustainable Intensification of Maize-Legume Systems in Eastern and Southern Africa (SIMLESA).

Since then, CIMMYT has leveraged its large network of partners to scale out CA. Between 2010 and 2015, CIMMYT, supported by a large group of donors including the Australian Centre for International Agricultural Research, the International Fund for Agricultural Development, the United States Agency for International Development and the Food and Agriculture Organization of the United Nations, helped over 173,000 farming households in the region adopt sustainable intensification practices.

Today, CA research at CIMMYT in Africa is increasingly focused on adaptation to the changing climate, which is leading to more erratic rainfall, increased heat stress and seasonal dry spells, in an effort to increase the use of climate-resilient cropping systems. CIMMYT’s work on CA in the region has shown that the practice can significantly increase farmers’ resilience to climate variability and change. Combining sustainable intensification practices with improved varieties has proved to increase productivity by 30-60 percent and income by 40-100 percent under drought conditions.

Despite CA’s successes, many smallholder farmers in developing countries still lack knowledge and understanding of sustainable agricultural practices and often revert to traditional farming practices that are labor-intensive and environmentally damaging. Also, CA systems are difficult to scale out if favorable policies and markets are not in place.

However, as demand for land increases, this fuels deforestation and depletes soil nutrients. CIMMYT has been working with farmers like Njambo since 2006 to adapt sustainable intensification practices like CA to his circumstances. In remote areas of Mozambique, where Njambo’s farm is located, CA systems provide significant benefits during dry spells because farmers have no access to irrigation and depend only on rainfall. In the 2013-2014 cropping season, Njambo harvested his best maize yield in the last six years thanks to CA.

Mineral fertilizer, for example, is a basic agricultural input, but its adoption and use remain limited in sub-Saharan Africa. Farmers apply less than 10 kilograms per hectare on average due mainly to poor distribution networks (especially in rural areas) and high prices that are 3-5 times those in Europe. Lack of knowledge and training on how to use mineral fertilizer and other agricultural inputs renders them ineffective.

New discoveries in agriculture and breeding must be adaptable and transferable to smallholder farmers. This means improving physical distribution of technologies, training, knowledge and information sharing, credit availability and creating enabling environments for growth.

Just before passing away in September 2009, world-renowned agricultural scientist Norman Borlaug famously implored the world to “take it to the farmer” – a call to action we must follow if we are to sustainably feed the world by 2050. Without a basic understanding of good agricultural practices, most smallholder farmers will not be able to grow enough crops to move past subsistence farming.

Maize seed systems in Africa: Understanding the basics

Written by on June 7, 2016. Posted in Features.

Maize is not only a staple in diets across sub-Saharan Africa – it is a cash crop that supports millions of farmer households. Maize is grown on over 33 million hectares in just 13 of 48 countries in the region – accounting for 72% of all maize produced in the region. This crop, without a doubt, is king.

However, rising temperatures and erratic rainfall patterns threaten maize production across the continent. Total crop loss occurs if there’s little or no rainfall at the flowering stage, when maize is most vulnerable. And when temperatures increase, soil moisture is quickly depleted and farmers have to resort to prolonged irrigation, a costly undertaking for smallholders.

Drought-tolerant (DT) maize varieties produce better yields both in good and bad seasons compared to most commercial varieties available in the region. Since 2006, CIMMYT has developed 200 drought-tolerant varieties and hybrids, many of which also possess desirable traits such as resistance to major diseases.

In addition to developing quality maize that is high yielding and disease resistant, the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project led by CIMMYT is working to ensure these improved varieties are affordable and attractive to farmers. Two and a half million smallholder farmers in Ethiopia, Kenya, Mozambique, Tanzania, Uganda and Zambia are expected to benefit from in-country partnerships and networks that boost production and distribution of DT maize seed. These countries account for 25 percent (or 252 million) of the population in sub-Saharan Africa, and 41 percent of maize production areas.

To access quality improved seed, farmers in Africa face various constraints such as high prices, low supply and limited knowledge about improved seeds. Through surveys conducted among nearly 5,000 farmer households in Kenya, Mozambique and Zambia, CIMMYT learned that when farmers buy seed, the traits they care most about are early crop maturity, yield, and tolerance/resistance to stresses such as drought and disease. In most cases, long-term use and preference for a particular seed variety influence buying habits, but now farmers are increasingly focusing on tolerance/resistance to drought, pests and diseases.

“Our key focus is on sustainable seed production and increasing demand,” said Kate Fehlenberg, DTMASS project manager. “This means building market skills for producers and creating an environment to entice risk-averse farmers to try new drought-tolerant varieties.”

CIMMYT is working with partners to increase farmer preference for DT seed by supporting promotional and marketing activities, and improving seed production capacity. CIMMYT will also work to ensure local institutions have the technological and production capacity to independently produce and distribute seed throughout DTMASS target countries.

Scaling activities will allow DT seed to spread across various geographical areas (scaling “out”) and build the capacity of local institutions to independently control sustainable seed production (scaling “up”). Both scaling up and out rely on giving stakeholders in the maize value chain compelling reasons to continue producing, distributing and consuming DT maize varieties.

Over 50 selected small- and medium-scale seed companies will be supported through training workshops on seed production and seed business management. Seed companies will also receive financial grants to support expansion activities such as purchasing special seed processing and packing equipment, restoring seed storage and other facilities, and marketing.

African ambassadors to Zimbabwe support improved agriculture technologies

Written by on May 30, 2016. Posted in News.

HARARE — Several African nation ambassadors to Zimbabwe pledged to step up support for improved agriculture technologies during a visit to The International Maize and Wheat Improvement Center’s (CIMMYT) Southern Africa Regional Office (CIMMYT-SARO) in Harare, Zimbabwe, in April.

The special field day and meeting, held as part of CIMMYT 50 celebrations, gave ambassadors from 12 African countries (Algeria, Botswana, Democratic Republic of Congo, Ethiopia, Namibia, Nigeria, Sudan, South Sudan, Tanzania, Uganda, South Africa and Zambia) the opportunity to learn about CIMMYT projects that are helping to strengthen food systems in sub-Saharan Africa and discuss future initiatives.

During the visit, the need to develop policies that promote smallholder farmers’ access to technologies that enable them to increase yields and improve crop resilience in the face of challenges such as droughts, as well as policies to address poverty, food security and economic growth surfaced as main priorities for the countries represented.

In his welcome address, Mulugetta Mekuria, CIMMYT-SARO regional representative, pointed out, “Sub-Saharan Africa’s food security faces numerous challenges, but drought is the most devastating because our farmers rely on rainfed agriculture. As you will see, CIMMYT’s work has created high-level impacts. But a host of challenges still hamper socioeconomic growth, such as reduced funding of agricultural research.”

According to Mekuria, CIMMYT’s work in sub-Saharan Africa aims to ensure farmers can access improved maize seed with drought tolerance and other relevant traits that contribute to higher, more stable yields, as well as technologies such as optimal fertilizer application. He noted that farmers in sub-Saharan African countries lag behind other regions in fertilizer application, applying, on average, less than 10 kg per hectare, which is 10 percent of the world average.

Another issue brought up was the lack of funding of agricultural research for development by most bilateral agencies on which African governments depend. The diplomats pledged to advise their governments of the need to increase support for improved agricultural technologies. They agreed that funding agricultural research work in line with the 2006 Abuja Declaration to allocate at least 1 percent of the donor country’s gross domestic product to agricultural research is of the utmost importance. Enhancing access to markets, extension services and inputs and supporting women and youth in agriculture were also identified as fundamental policy issues that need to be urgently addressed. Strong partnerships and collaborative efforts between various African governments, CIMMYT and the private sector were also called for.

The ambassadors were briefed on CIMMYT’s achievements in the region, and how, in partnership with national agricultural research systems and private seed companies, they have released more than 200 drought-tolerant maize varieties that perform significantly better under moderate drought conditions than varieties already on the market, while yielding the same – or better – in a normal season. More than 6 million farmers in sub-Saharan Africa grow improved drought tolerant maize varieties developed by CIMMYT and partners.

A wide range of CIMMYT-SARO technologies were also showcased, including sustainable intensification strategies based on the principles of conservation agriculture. Compared to conventional cropping practices, conservation agriculture increases yields after two to five cropping seasons due to the combined benefits of minimum soil disturbance, crop residue retention and crop rotation. Conservation agriculture has been successfully promoted in Malawi, Mozambique, Zambia and Zimbabwe for the past 10 years. For example, yield increases of 20-60 percent were recorded in trials in farmers’ fields in Malawi, while in Zambia and Zimbabwe, yields increased by almost 60% using animal traction innovation agriculture technologies.

Other technologies demonstrated were pro-vitamin A maize and quality protein maize. The diplomats learned that CIMMYT had released eight pro-vitamin A hybrids with 28% more vitamin A content in Zambia (4), Malawi (3) and Zimbabwe (1). On improved varieties, CIMMYT sent 823 seed shipments (1.3 million envelopes) to 835 institutions worldwide over the last four years.

“The success of our projects goes beyond the breeding work. Through the value chain approach, our work now is to ensure that seed companies and, ultimately, maize farmers benefit from the seed that is developed with their needs in mind. Getting drought-tolerant maize and other improved seeds to the markets and farmers is a critical next step,” said James Gethi, CIMMYT seed systems specialist.

Harnessing maize biodiversity for food security, improved livelihoods in Africa

Written by on May 20, 2016. Posted in Features.

HARARE (CIMMYT) — As CIMMYT joins the world in celebrating the International Day for Biological Diversity on 22 May, it can take pride in the diverse maize varieties it develops which have improved the livelihoods and health of smallholder farmers globally.

These varieties have brought tremendous benefits to smallholders in sub-Saharan Africa (SSA). Over 90 percent of agricultural production in SSA is rainfed, which puts farmers at risk for drought and heat in addition to the poor soil fertility, pests and diseases they face. Drought alone damages about 40 percent of all maize crops in SSA, endangering the livelihoods and food security of millions of smallholder farmers.

Stress tolerant maize not only reduces risks for farmers in the face of unpredictable environmental and biological conditions, it also allows more stable crop production. The International Maize and Wheat Improvement Center (CIMMYT) breeds high-yielding, locally-adapted maize varieties with farmer-preferred traits such as drought tolerance, nitrogen use efficiency, and disease and insect pest resistance. Many of these varieties also have increased nutritional traits such as high protein quality and increased provitamin A content, which help increase children’s weight and height growth rates and reduce childhood blindness.

“Since working with CIMMYT, we have unlocked our production potential, ‘’ said Sylvia Horemans, Marketing Director of Zambian-based Kamano Seeds. Since its establishment in 2012, Kamano Seeds has benefitted from CIMMYT to strengthen its work in maize breeding besides technical support on maize seed production and marketing.

“Increasing adoption of these stress tolerant maize varieties is helping African farmers cope with drought and climate change, improve yields at household level and thereby enhance the livelihoods and food security of tens of millions of farmers,” said Cosmos Magorokosho, CIMMYT-Southern Africa maize breeder.

These drought-tolerant varieties have proven resistant despite harsh conditions brought on in southern Africa by an intense El Niño, according to Magorokosho. “Significant impacts have been observed in plots of smallholder farmers who grow these varieties.”

In 2014, over 54,000 metric tons of certified seed of the stress tolerant maize varieties were produced and delivered by partner seed companies for planting by smallholders. By the end of that year, more than five million smallholders had planted the improved drought tolerant varieties on over two million hectares, benefiting more than 40 million people in 13 countries in SSA.

Today, there are more than 200 stress tolerant maize varieties that yield the same or more than commercial varieties under average rainfall, and more importantly, produce up to 30 percent more than commercial varieties under moderate drought conditions. Armed with these improved varieties, CIMMYT is assuming a greater role to ensure stress tolerant maize reaches nearly five and a half million smallholder households in SSA by the end of 2019.

“The rain is very little here, but even with a little rain, this seed does well,” says a smallholder farmer Philip Ngolania, in south-central Kenya, referring to a drought-tolerant maize variety he planted during the 2015 crop season. “Without this seed, I would have nothing. Nothing, like my neighbours who did not use the variety."

“In close collaboration with our partners, we were able to create excitement about what can be achieved with drought tolerant maize in Africa,” said Tsedeke Abate, leader of CIMMYT’s Stress Tolerant Maize for Africa project. CIMMYT is working with national agricultural research systems, international research centers, and other development programs to disseminate improved maize seed to smallholder farmers in SSA through small-and medium-sized seed companies.

“The work we have undertaken on drought tolerant maize has created significant impacts. However, several challenges still remain,” cautioned B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program MAIZE. One of these challenges is maize lethal necrosis (MLN), which emerged in Kenya in 2011 and has since devastated maize crops across East Africa. CIMMYT is working to generate improved stress tolerant maize varieties with resistance to MLN and other major diseases.

Maize production in Africa is growing rapidly, making maize the most widely cultivated crop on the continent, and the staple food of more than 300 million people. Providing farmers with diverse, improved seed choices will thus strengthen food security, health and livelihoods in SSA.

Millions of smallholders in Africa benefit from climate resilient drought-tolerant maize

Written by on April 21, 2016. Posted in Features.

NAIROBI, Kenya (CIMMYT) – At least 40 million smallholder farmers throughout sub-Saharan Africa are profiting from more than 200 new drought-tolerant varieties of maize produced as part of the Drought Tolerant Maize for Africa (DTMA) Project, according to scientists at the Center for International Maize and Wheat Improvement (CIMMYT).

The project, underway between 2007 and 2015, led to the development of varieties with traits preferred by farmers that have successfully made smallholders in 13 countries more resilient to the erratic effects of climate change on growing conditions.

“Smallholder farmers in this region plant maize varieties that are obsolete and end up getting poor harvests, but that’s changing now thanks to the gallant efforts of the DTMA team that has released and commercialized a large number of modern varieties,” said Tsedeke Abate, the CIMMYT scientist who led the project. “Thanks to the new drought-tolerant varieties, many families have managed to overcome harsh growing conditions and boost yields substantially.”

In 2014 alone, more than 5 million smallholder farmer households planted the new varieties on 2.1 million hectares (5.2 million acres), an area roughly the size of El Salvador. Overall, 54,000 metric tons of high quality seed were produced in 2014 through the DTMA project, which received funding from the Bill & Melinda Gates Foundation, Britain’s Department for International Development, the Howard G. Buffet Foundation and the U.S. Agency for International Development (USAID).

COMPLEX CHALLENGES

“The adoption of the improved drought tolerant seed varied from one country to another and each county had unique challenges that made it difficult for some farmers to take up the new varieties. Some farmers were not aware of the availability of the seed in their markets, for some the seed was not available or the price was high,” Abate said. “We worked with national seed companies in these countries to increase production of certified seed so that many more farmers can buy the seed at an affordable price as well as demonstrating the benefits of the new varieties.”

Anthony Mwega, a farmer and leader in Olkalili village, in Hai district a semi-arid area in northern Tanzania about 600 kilometers (370 miles) from the capital Dar es Salaam, beat the price constraint by mobilizing 66 farmers from his village and neighboring villages Makiwaru and Ngaikati to pool resources and buy 5 metric tons of HB513 – a drought-tolerant and nitrogen-use efficient variety – at a very affordable price from Meru Agro Tours and Consultant Seed Company.

“The overall purchasing price we bought the seed for was about 50 percent less than the market price because we bought it in bulk,” said Mwega. “I saw how good the maize performed in demonstrations organized by Meru Agro during the 2014 planting season with extremely low rains, and knew this is a variety that my people would definitely benefit from.”

Scientists project that millions more farmers will gain access to and plant the new varieties due to collaborations with more than 100 national seed companies, which continue to make a significant contribution to the improvement of seed systems in Angola, Benin, Ethiopia, Ghana, Kenya, Malawi, Mali, Mozambique, Nigeria, Tanzania, Uganda, Zambia, Zimbabwe.

“Collaboration with CIMMYT through the DTMA project has been extremely instrumental in facilitating me to release my own varieties,” said Zubeda Mduruma of Aminata Seed Company in Tanga, Tanzania who has collaborated with CIMMYT both in maize breeding and production work since 1976.

“I was able to get some of the best germplasm, evaluate them through on-farm and on-station trials, and successfully released three of the best drought tolerant varieties in the market, including one quality protein DT variety that is very popular among women because of its nutritional value. With the quality of maize we get from CIMMYT, it’s very possible to release new improved varieties every year with much better yield compared to popular commercial varieties in our shops.”

The story of this success is told through a series of pictures and profiles of DTMA target countries. Each country profile illustrates the context of national maize production and the changes underway thanks to released drought-tolerant varieties.

The DTMA project will continue, first as the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) initiative. Under the project, which is funded by USAID, CIMMYT scientists aim to facilitate the production of close to 12,000 metric tons of certified seed for use by about 2.5 million people, in Ethiopia, Kenya, Malawi, Mozambique, Tanzania, Uganda and Zambia.

In partnership with the International Institute of Tropical Agriculture who partnered with CIMMYT in DTMA work, the new Stress Tolerant Maize for Africa project will also carry forward the success and invaluable lessons from DTMA and CIMMYT’s Improved Maize for Africa Soils project, to develop new stress tolerant varieties to help farmers mitigate multiple stresses that occur concurrently in farmers’ fields.

Going further down the path to bolster Africa’s maize sector

CIMMYT empowers a new generation of maize breeders in Zambia

CIMMYT recently conducted an intensive three-week training course in Zambia for 38 young maize breeders–including 12 women–to provide them the knowledge and skills needed to apply modern maize breeding methods in their agricultural research and development programs. Participants from national programs and private seed companies from 12 African countries and Pakistan attended the course.

Moses Mwale of the Zambia Agricultural Research Institute (ZARI) officially opened the course, and said the training was critical as agriculture contributes over 40% of Zambia’s gross domestic product and provides 70% of all employment in Africa; up to 80% of the African population lives in rural areas and is heavily dependent on agriculture for their livelihoods.

According to Mwale, “Despite its immense potential, maize has underperformed in Africa in recent years. The major cause is lack of investment, reliance on rainfed agriculture, low usage of improved seed, and the lack of adequate agricultural research and development, resulting in low production, productivity, and high transaction costs in agribusiness ventures.”

For the first time, a significant part of the course was devoted to the subjects of crop management and gender mainstreaming in maize research and development.

CIMMYT agronomist Isaiah Nyagumbo presented the crop management practices recommended to boost yields, productivity, and income, and to conserve natural resources. He emphasized that investments in maize breeding pay off when crop management on farm is improved. Nyagumbo also demonstrated new land preparation equipment recommended for use with conservation agriculture, including jab planters, dibble sticks, Li seeder or planting hoe, and animal traction rippers.

Vongai Kandiwa, CIMMYT gender specialist, spoke about “Leveraging Gender Awareness in Maize Breeding and Seed Deployment.” Revealing existing evidence of gender gaps in technology awareness and adoption, she highlighted the importance of developing maize technologies that meet the needs of both men and women farmers. Kandiwa also shared insights on gender-responsive approaches for conducting on-farm trials and building awareness, especially of newly released varieties.

During the training course, CIMMYT physiologist Jill Cairns briefed participants on preparing and making effective presentations––a challenge for both distinguished and new scientists.

Several scientists highlighted recent developments in maize improvement such as the use in maize breeding of doubled haploids, molecular tools, transgenics, and precision phenotyping. Key themes included advanced phenotyping by CIMMYT physiologist Zaman Mainasarra, who demonstrated the use of unmanned aerial vehicles for digital imaging and fast, cost-effective, and accurate phenotyping data collection.

Other subjects included theoretical conventional breeding, breeding for abiotic stress in line with climate change, breeding for biotic stresses with emphasis on preventing the spread of maize lethal necrosis (MLN) disease, and breeding for improved nutritional quality (quality protein maize and pro-vitamin A maize). Max Mbunji of HarvestPlus gave a presentation on Zambia’s progress on developing and delivering pro-vitamin A maize over the past seven years.

Variety release and registration, seed production, and seed business management in Africa were also featured during the course. Trainees learned how to scale up breeder seed to certified seed, maintain genetic purity and quality, and support upcoming seed companies, while complying with existing seed legislation, policies, and procedures in different countries.

Participants went on a field trip to HarvestPlus, where they learned more about pro-vitamin A analysis. They also visited ZARI’s Nanga Research Station to observe drought screening and seed production activities conducted by Zambia’s national maize breeding program.

At the end of the course, one of the participants, Annah Takombwa, acting technical affairs manager at Zimbabwe’s National Biotechnology Authority, said, “Many thanks for affording me the opportunity to take part in GMP’s New Maize Breeders Training. It was a great honor and privilege. I am already applying the skills and knowledge gained in my day-to-day activities.”

CIMMYT Global Maize Program (GMP) maize breeders Cosmos Magorokosho, Stephen Mugo, and Abebe Menkir of the International Institute of Tropical Agriculture (IITA) organized and coordinated the course. Participants were sponsored through various GMP projects, including Drought Tolerant Maize for Africa, Drought Tolerant Maize for Africa Seed Scale-up, the Doubled Haploids project, Water Efficient Maize for Africa, Improved Maize for African Soils, USAID Heat project, MLN project, HarvestPlus, and private seed companies ZAMSEED and SEECDCO.

CIMMYT-SARO steps up efforts in war against malnutrition

Written by on August 3, 2015. Posted in Features.

CIMMYT-Southern Africa Regional Office (CIMMYT-SARO) is stepping up efforts to combat malnutrition, especially among women and children, through agricultural research and the release of orange maize varieties.

Orange maize is nutritionally enhanced and provides higher levels of vitamin A than white maize. In addition, orange maize varieties are high-yielding, disease resistant and drought tolerant, which helps farmers face challenges posed by recurrent droughts and climate change.

“Orange maize rich in beta-carotene could bring positive benefits to maize-dependent communities, particularly women and children, by providing up to half of their daily vitamin A needs,” said Thokozile Ndhlela, CIMMYT-SARO maize breeder, who is working on the orange maize breeding project. According to Ndhlela, the project is conventionally breeding non-genetically modified orange maize to endow it with higher levels of beta-carotene. Beta-carotene is a naturally occurring plant pigment that the body converts into vitamin A.

Vitamin A deficiency is a serious health threat that is prevalent in Southern Africa (SA) and may lead to blindness, reduced disease immunity and other health problems. In Zambia, for example, it affects more than half of children under five years of age, according to a Feed the Future newsletter. Feed the Future is the US Government’s global hunger and food security initiative.

In neighboring Zimbabwe, one in every three children suffers from stunted growth (as much as 32%) or chronic malnutrition, which contributes to 12,000 deaths each year, according to the United Nations Children’s Fund (UNICEF). Malnutrition is most prevalent in Zimbabwe’s rural areas, which are home to over 75% of the country’s entire population (about 13 million).

While vitamin A is available from other food sources such as oranges, dark leafy vegetables and meat, these are not always available or are too expensive for the ordinary person in SA. As a result, most people eat a lot of white maize, which has no beta-carotene.

Orange maize can be eaten as a porridge-like staple food called nshima in Zambia and sadza in Zimbabwe. It can also be used to prepare other traditional foods made from maize.

CIMMYT is working with HarvestPlus, a CGIAR organization that breeds and disseminates micronutrient-rich staple food crops to reduce hidden hunger in malnourished populations. The orange maize project was initiated in Harare, Zimbabwe, in 2004, but later moved to Mexico. Since the subtropical environments in Mexico are similar to those in SA, the germplasm developed in Mexico has adapted well to SA environments.

Three hybrids (GV662A, GV664A, and GV665A) were extensively tested in Zambia and released by the Zambia Agricultural Research Institute in partnership with HarvestPlus. These hybrids have a yield potential of 9-11 tons per hectare. Hybrid GV665A will be released in Zimbabwe in October of this year. Three seed companies are marketing the released hybrids on an exclusive basis in Zambia and four other pre-release hybrids are being tested in national performance trials.

Since 2012, HarvestPlus has provided orange maize to more than 10,000 farming households in Zambia. It is working with the private sector to reach 100,000 farmers by the end of this year.

Zimbabwe’s Crop Breeding Institute has expressed an interest in sending two of these hybrids to the Seed Certifying Authority of Zimbabwe for quality testing during the 2015/2016 agricultural season. Malawi, another SA country, has also identified hybrids for release in 2016.

Livestock key to breaking Zambia’s poverty trap

Written by on August 3, 2015. Posted in Blogs.

Malende is a small village near the town of Monze in southern Zambia, a region that has been a focus of CIMMYT’s major research programs since 2005 and where cropping systems based on the principles and practices of conservation agriculture have been introduced.

Farmers in Malende are typical of smallholder farmers in Sub-Saharan Africa; they farm relatively small areas, their soils are often degraded and they suffer serious effects of climate variability such as increased heat stress, erratic rainfall and intra-seasonal droughts. Subsistence farming is predominant, as farmers lack access to functional markets for both inputs and produce. Most farmers in Malende rely on manual or animal traction and lack access to alternative farm power, which limits their landholdings to around five hectares.

CIMMYT has been working with partners to implement climate-resilient technologies such as direct seeding, mulching and diversified crop rotation to increase farmer productivity and environmental resilience. A survey conducted during the implementation of an International Fund for Agricultural Development (IFAD) project classified Zambian farmers involved in different farming operations by their household characteristics, i.e., land size, cattle and income. To validate the study of farmer typologies, CIMMYT, in collaboration with Zambia’s Ministry of Agriculture and Livestock, interviewed a smallholder farmer who owned no cattle and a farmer who owned more than 15 head in March 2015.

Jacob Sibanje farms a total of five hectares. His family consists of five adults and five children, all of whom work on the farm. He has practiced conservation agriculture for many years, produces consistently stable yields, and has started rotating maize with groundnuts, cassava, cowpeas and sweet potatoes.

When asked how his farm operations are doing, Sibanje answered, “I am struggling!” Despite progress achieved through conservation agriculture, the high price of farm inputs (specifically fertilizer and herbicides) and the lack of formal markets for his produce erode his profits annually. This means he has to take on off-farm work to get by. Sibanje’s maize harvest is solely for home consumption, and his situation is unstable, since he has to rent livestock to cultivate his land.

Lyson Sakala cultivates six hectares and supports his family of three adults and two children. Unlike Sibanje, Sakala’s approach is clearly market oriented. He practices conservation agriculture on three hectares, where he rotates maize with soybeans, cowpea and sunflower both for the local market and home consumption. The other three hectares are used as pastureland for livestock.

Sakala feeds all crop residues to his animals and applies manure mainly to the grazing area. He produces 15 liters of milk daily; seven are for home consumption and the rest are sold. Cattle are also a source of cash in case of a family emergency. Sakala can count on selling two to four cows every year for an average price of US $197 per cow. Combined milk and meat revenue allows him to purchase fertilizers at a much higher price than his fellow farmers in Malende. As Sakala’s profits increased, he started employing two farm helpers, and is now able to send all his children to school. He also obtains fodder from his neighboring farmers as supplementary feed during the dry winter season in exchange for renting animals during planting time.

How can Sibanje achieve the same success as Sakala?

CIMMYT used farm typologies based on diverse socio-economic and agricultural criteria to define different livelihood strategies in southern Zambia, and owning livestock was identified as one way of breaking the poverty trap many farmers like Sibanje are stuck in. CIMMYT is also demonstrating the added value of manure, defining the trade-offs between leaving residue on the soil and feeding it to cattle; we also identified the agroecological and socioeconomic conditions where crop-livestock integration can bring positive solutions to farmers.

When he was re-visited in June, Sibanje had already bought four heifers with the current season’s produce. He also plans to modify his farm operations to create a mixed crop-livestock system with the goal of maximizing the whole system instead of only one component, which will generate positive trade-offs.

According to the Food and Agriculture Organization of the United Nations, “The choice of mixed farming is not always a sign of improvement of the situation in which people may find themselves.” However, Sibanje and Sakala show that though all smallholders may not become market-oriented livestock farmers, they should at least own enough cattle to avoid having to rent animals for plowing and to have manure and reduce their dependency on expensive mineral fertilizers.

Green manures help Zambian and Malawian farmers feed crops and livestock

The Food and Agriculture Organization of the United Nations (FAO) has tasked CIMMYT with a new project to introduce green manure cover crops to smallholder farmers in eastern Zambia and central and southern Malawi.

Green manures can improve fertility, protect soils and provide fodder and grain for farm animals and humans. They also help substitute for mineral fertilizers, which are costly for landlocked African nations to produce or import. Most smallholder farmers cannot afford them and apply less than 10 kg per hectare of fertilizer to their crops, according to a 2013 study on profitable and sustainable nutrient management systems for eastern and southern African smallholder farming systems.

“This is less than one-tenth of average fertilizer rates in prosperous countries and a key reason why maize yields in southern Africa are around only one ton per hectare,” said Christian Thierfelder, CIMMYT conservation agriculture specialist based in southern Africa. “As a result, many farm families in the region remain food insecure and caught in a seemingly unbreakable cycle of poverty.”

With full participation of farmers, the project will test green manures in rotation with maize and as intercrops or relay crops in different farming systems, according to Thierfelder.

“Improved, high-yielding maize can show its potential only under good agronomic practices, such as optimal plant spacing, timely planting, good weed and pest control and adequate fertilization,” Thierfelder explained. “Farmers in Europe and the Americas have followed these basic principles for generations, and some of the ideas spread to Asia and Africa during the Green Revolution. But in Africa mineral fertilizers are most often used by rich farmers and for high-value crops.“

“Improved maize that tolerates drought and other stresses, coupled with conservation agriculture practices –minimum soil disturbance, crop residue retention and diversification through rotations and intercropping systems – are farmers’ best bet to escape the poverty trap,” Thierfelder said.

Keeping crop residues on the soil is a critical component of conservation agriculture, but the residues are traditionally fed to livestock, which also underpin smallholder farmers’ livelihoods. So the use of conservation agriculture hinges on the ability of a cropping system to produce enough biomass to feed farm animals while providing an adequate residue cover. This requires a source of fertilization to feed the cropping system.

The FAO-CIMMYT project will address this by allocating green manure cover crops for different uses. “Over the last five years, CIMMYT’s global conservation agriculture program has identified potential cover crop varieties that fit farmers’ needs,” Thierfelder said. “Velvet bean, lablab, cowpea, sunnhemp or jackbean can provide 10-50 tons per hectare of extra biomass for livestock. They can also leave 50-150 kilograms per hectare of nitrogen in the soil and do not need any additional fertilizer to grow. Finally, lablab and cowpea provide grain that humans can eat.”

One approach Thierfelder promotes is for a farmer to dedicate part of her land to grow maize under conservation agriculture practices, and other areas to sow green manures, nutritional and cash crops that increase soil fertility and household income. “In this way, a farmer can diversify and gradually have money to purchase mineral fertilizer, boost productivity and move out of poverty.”

Green manure cover crops are not new in Africa. Why should they work this time?

According to Thierfelder, there are examples of success in northern Mozambique with CIMMYT’s partner organization CARE International, using lablab and improved germplasm in cassava-based CA systems can increase cassava tuber yields from 4 to 13 tons per hectare, without using additional mineral fertilizer. “In Tanzania, lablab and other green manures are an important part of the cropping system,” he said. “In Zimbabwe, successful experiments with maize and green manures under an ACIAR-funded ZimCLIFFS project also provide hope. The FAO-CIMMYT project will guide the way on integrating green manures cover crops into these farming systems.”
