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

Vitamin A deficiency is considered a major public health problem in Tanzania affecting over 30 percent of the population, mostly children in preschool and women of reproductive age. It can result in morbidity, loss of vision or blindness and even death.
Provitamin A maize (PVA) is a special type of biofortified maize that contains high levels of beta-carotene. Beta-Carotene is an organic, red-orange pigment abundant in plants and fruits and gives PVA maize an orange color. It is converted to vitamin A in the body after consumption to provide additional nutritional benefits.
Biofortification enhances the nutritional value of staple food crops by increasing the density of vitamins and minerals in a crop through either conventional plant breeding, agronomic practices or biotechnology. This can significantly reduce the prevalence of “hidden hunger” due to micronutrient deficiency.
Maize – a staple food in Tanzania – can serve as a cheap and sustainable source of vitamin A, especially for vulnerable populations. Stores of vitamin A in 5 to 7 year old children improved when they ate PVA maize, according to HarvestPlus research.
PVA maize was recently introduced in Tanzania through the Building Nutritious Food Baskets Project (BNFB), a joint effort by the Government of Tanzania, Tanzania Official Seed Certification Institute, the International Maize and Wheat Improvement Center and national seed companies. Two Provitamin A maize varieties – Meru VAH517 and Meru VAH519 – were released for commercial production by Meru Agro Tours and Consultants in September 2016.
To catalyze efforts to increase planting and consumption of PVA maize, different actors along the maize value chain launched a PVA maize platform for Tanzania. The platform will serve as an information and knowledge center on PVA maize in the country by linking different stakeholders to relevant authorities on matters relating to PVA maize, as well as provide capacity development opportunities for members on critical gaps relating to PVA maize knowledge and biofortification in general.
Membership of the platform is expected to become multi-sectoral and multi-disciplinary and include actors such as the ministry of health, school feeding programs and academic institutions. The platform will be led by national partners.
The International Potato Center is collaborating with a consortium of CGIAR research centers, the governments of Nigeria and Tanzania and national partners on BNFB, which is addressing hidden hunger by catalyzing sustainable investments for the production and utilization of biofortified crops. The project mainly targets rural populations, especially young children under the age of five and women of reproductive age, in Nigeria and Tanzania.

LIWONDE, Malawi (CIMMYT) — Esnath Shaibu, a smallholder farmer from Matandika, southern Malawi was a host farmer with the International Maize and Wheat Improvement Center (CIMMYT) for seven years who helped the organization conduct research trials on sustainable agriculture intensification with support from the International Fund for Agricultural Development (IFAD).
Shaibu’s farm in Matandika, like most other farms in this area, is small and restricted to less than one hectare (ha) per household. Matandika is highly affected by the effects of climate change and a growing population is putting more pressure on dwindling land resources. Farmers have experienced more droughts in recent years which has affected food and nutritional security. Investment into soil conservation and maintaining soil fertility has therefore become critical.
A good proportion of Shaibu’s livelihood is generated from the land of his .3 ha research plot, which evaluates conservation agriculture (CA) systems in the environments and circumstances of Matandika.
The fields in Matandika are on hillsides and need to be seeded with as little disturbance as possible to avoid soil erosion and run-off. Farmers have also understood the value of crop residues and integrate legumes as intercrops in their fields to intensify their farming systems and increase diversification. Optimal plant spacing, early planting and precision application of fertilizers have been other good agriculture practices that farmers perfected in this area.
During the trials, Shaibu practiced a direct seeded CA method, intercropping maize and pigeonpea, and compared the results with conventional tillage practices just planting maize. Yields from Shaibu’s plots were increasingly stable under the CA system, as they proved to be more resilient against in-season dry-spells, drought and unevenly disturbed rainfalls which often fell at great intensity.
Shaibu graduated from the CA program in 2014, but continued to implement the same principles and practices on his own without CIMMYT’s interference or support.
When questioned about his rationale during a field visit in 2017, Shaibu said “we saw something good in it,” and his healthy looking crop spoke for itself.
Shibu’s case demonstrates that technology adoption is only successful if we as development practitioners work ourselves out of a job. He is a true adopter who has continued investing his own resources to produce a good maize crop on a significant proportion of his land by applying CA principles at highest standards. Shaibu has also converted other fields he owns to CA and continues to be an influential advocate in the community for the benefits of CA.

MEXICO CITY (CIMMY) – New evidence shows that not only do improved maize varieties increase crop productivity and farmer income, they can also decrease child malnutrition.
Malnutrition is the largest single factor contributing to the global disease and accounts for about 30 percent of infant deaths. Malnutrition is particularly widespread among children in Zambia, and is one of the leading contributors to the high burden of disease in the country. Around half of all Zambian children under the age of five are stunted, or too short for their age, indicating chronic malnutrition.
A recent Food Securitystudy published by scientists at the International Maize and Wheat Improvement Center (CIMMYT) found that adoption of improved maize varieties significantly reduces the probability of stunting by an average of 26 percent in Zambian children.
The paper evaluated the impact of improved maize varieties with traits such as higher yields, early maturation and resistance to disease, on stunting in more than 800 households across eastern Zambia using an endogenous switching probit model to identify the determinants of child nutritional status and impact of improved maize varieties.
Researchers found that adoption of improved maize varieties held a key role in improving the income earning opportunities for rural households through increased maize yields. More maize – a staple of the Zambian diet – coupled with more money to spend on high calorie and protein foods led to a decline in malnutrition.
However, realizing the full benefits new technologies like improved maize can have on communities requires increased investment and policy support aimed at enhancing adoption by farmers, according to the study. Social dynamics and increasing education, especially among women, are particularly critical for promoting nutrition-enhancing child care practices, given that the probability of stunting was reduced by 16 percent with each additional year of schooling for the most educated female household member among adopters in the study.

NAIROBI, Kenya (CIMMYT) – For over 50 years, CIMMYT has led the research and development of quality, improved seed, designed to help farmers mitigate the effects of climate change while improving livelihoods.
Every new variety released is driven by farmer needs and preferences, with desirable traits such as pest and disease resistance, drought and heat tolerance as well as water and nutrient use efficiency. With improved maize seed, farmers not only benefit from increased stress tolerance, they also enjoy higher yields, increased nutritional value and improved income from grain sales.
To ensure that quality seed standards are maintained, CIMMYT supports partners such as national agricultural research institutions and seed producers in acquisition and production of pure early generation seed, which is then tested by national quality assurance and certification agencies before certification and release.
Seed certification process
Seed certification is a rigorous process of testing new maize varieties before they are made available to farmers and follows an often lengthy three-step process.
The first step – value for cultivation and use, or national performance trials in some countries, – compares traits of the new variety to others already in the market to determine its value. For a new variety to enter the market it must have significant value to the farmer, such as higher tolerance to stress, or added nutritional value. It is at the end of this valuation process that a variety is registered, which takes about 2-3 years.
Next, a distinctiveness, uniformity and stability test (DUS) is performed on the seed sample provided to ensure that it is unique, uniform and will not deteriorate over time after its release. The DUS also helps to determine if an identical variety already exists and is registered, in order to avoid conflict among companies that are responsible for variety commercialization. The characteristics used to compare these materials are developed by breeders, and help distinguish different varieties. The length of time for DUS test varies by country, but on average the minimum is two planting seasons, about two years in most countries, or one year in others.
Finally, the government approves the variety for release and commercialization. In some countries, such as Tanzania, there is an extra classification of seed know as quality declared seed which is certified seed that has been through fewer steps of certification. It is perceived to be of a lower quality than regular certified seeds, and is therefore cheaper. Seed certification protects farmers from unscrupulous traders who would otherwise sell poor quality seed or grain packaged as seed.
Seed certification and commercialization can take 6-11 years, depending on how efficient a country’s system is. This lengthy and costly process can sometimes create backlogs, slowing release and commercialization of new varieties. This can discourage some seed companies from producing improved varieties, thus sticking to tried, tested and profitable varieties no matter how old they are. Commercializing a new variety is a huge investment in terms of cost, expertise, promotion and labor, so the longer certification process draws out, the more costs a company incurs. Farmers in turn continue to purchase the varieties that are always available, keeping them in demand.
Expecting seed companies to replace an old variety for an improved one is somewhat complicated, since this is a purely business decision where profits are priority. In some cases, dropping a popular variety to promote a new one could jeopardize a company’s market share, brand recognition and potentially put them out of business. This is why old varieties like Matuba in Mozambique, SC513 in Zimbabwe and H614 D in Kenya remain popular, despite being decades old.
Older seed dominating the market causes both farmers and seed companies to miss out on potential benefits and profits higher-performing seed can bring. Several strategies to retire old maize varieties and build demand for improved ones can be used, including demonstrating old and new varieties side by side in areas where target markets exist. This way, farmers themselves drive the process and start the switch to new varieties. Seed producers can emphasize a specific characteristic in the variety that will benefit the farmer. For instance, farmers in an area prone to maize lethal necrosis (MLN) are more likely to adopt a resistant variety, and eventually make a permanent switch once this characteristic is proven to be true.
Government policies can also encourage the retirement of old varieties, for instance through subsidies on seed production with requirements to only include new materials. CIMMYT, through its various projects, gives competitive financial grants only to companies that produce improved maize seed. An extreme and potentially detrimental option would be to cut off funding and other support to seed companies that refuse to phase out old varieties.
The Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project works in six countries in eastern and southern Africa to produce and deploy affordable drought tolerant, stress resilient, and high-yielding maize varieties for smallholder farmers. DTMASS employs innovative and impactful strategies to promote uptake and adoption of these improved seed varieties, as well as sharing agronomy and other agricultural information directly with farmers to improve crop management.
Led by CIMMYT and funded by the United States Agency for International Development, DTMASS is implemented through strategic partnerships with national agricultural research systems, as well as public and private seed producers.
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 theGlobal 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.
As climate change threatens to increase the incidence of plant pests and diseases, action must be taken to protect smallholder farmers and global food security.
At this year’s UN Climate Talks, CIMMYT is highlighting innovations in wheat and maize that can help farmers overcome climate change. Follow @CIMMYT on Twitter and Facebook for the latest updates.

MBEYA, Tanzania (CIMMYT) – To achieve its objective of sustainably increasing the availability of new drought tolerant maize varieties in eastern and southern Africa, the International Maize and Wheat Improvement Center (CIMMYT) supports seed company partners in enhancing their capacity to produce foundation and certified seed.
AgriSeed began as a small seed company in Tanzania in 2010, producing seed using donor grants to get established, and selling seed through a government subsidy program. When the program closed in 2013, collapse of the business was a real threat. However, in 2015 AgriSeed received its first grant from the CIMMYT-led Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project to produce early generation seed of a new hybrid called WE2112, and are now on their way to sustainability.
“When the African Agricultural Technology Foundation announced licensing of this variety, we jumped at the opportunity,” said Ambonesigwe Mbwaga, Director of AgriSeed. “We wanted something we could call our own, since all our other products are public and can be produced by another company.”
WE2112, marketed as AgriSeed H12, is the first hybrid sold by the company, with CIMMYT supporting the transition from open pollinated varieties to improved hybrids. Profitable sales of improved maize varieties are key to sustained and scaled production by the private sector to ensure access in the long run. Being among the few seed companies producing this particular hybrid gives AgriSeed an edge in the market.
“With AgriSeed, we started from scratch: increasing the parents, increasing the inbred lines, single crosses, and so on,” said James Gethi, maize breeder and DTMASS technical lead for Tanzania. “My main excitement this year is to see the product of that support coming to fruition. They now have a certified crop, from zero, and have something to sell.”
According to Mbwaga, the product is “flying off the shelves.” While only three tons of AgriSeed H12 were produced and sold in 2016, AgriSeed expects this figure to rise to over 50 tons in 2017 due to increased production capacity, and the huge demand created from the minimal sales. Also of note is the AgriSeed H12 packaging, whose smallest pack is five kilograms, much larger than the one and two kilogram bags often sold of new products to smallholder farmers. This is a strong indicator of demand and confidence in the product, since it costs more to purchase the bigger bag.
To promote sales, the company has set up over 100 demonstration plots for 2017 with DTMASS support, most of them in the southern Tanzania towns of Mbeya, Mbozi and Mlonge. Unlike the traditional highway setups, AgriSeed is concentrating demos along roads in villages, increasing access to farmers away from major roads. This aims to boost sales but also helps the United States Agency for International Development (USAID), the project’s funder, reach its Feed the Future goals to reach remote smallholder farmers.
Through technical and financial support and capacity building initiatives, DTMASS works closely with AgriSeed and other partners in eastern and southern Africa to bring affordable, improved maize seed to 2.5 million people. With funding from the USAID, DTMASS aims to meet demand and improve access to good-quality maize through production of improved drought-tolerant, stress-resilient, and high yielding maize varieties for smallholder farmers.

HARARE, Zimbabwe – The maize lethal necrosis (MLN) quarantine facility in southern Africa was officially opened in Zimbabwe on April 20, 2017 to enable safe introduction and exchange of novel maize germplasm from CIMMYT to partners in southern Africa.
Set up by the International Maize and Wheat Improvement Center (CIMMYT), with the approval of the government of Zimbabwe, the work for establishing the facility at the Plant Quarantine Station at Mazowe, outside Zimbabwe’s capital Harare, was initiated in the last quarter of 2015. The five hectare MLN quarantine facility funded by the United States Agency for International Development, is the first of its kind in southern Africa and will be used to safely import elite maize breeding materials from CIMMYT to southern Africa.
MLN is a devastating disease that causes huge economic losses if it occurs, particularly for smallholder farmers who frequently do not have means to control it. MLN was first detected in Kenya in 2011, and has since been reported in Democratic Republic of the Congo, Ethiopia, Rwanda, Tanzania, and Uganda. It is caused by a double infection of maize plants by two viruses: the maize chlorotic mottle virus and the sugarcane mosaic virus. Severe infestation can result in total yield loss. MLN-causing viruses are transmitted not only by insect vectors, but also by seed. There is an urgent need to prevent the deadly disease from moving further south.
The MLN quarantine facility is now functional. To date, over two hectares of land have been planted successfully with maize breeding materials imported from Kenya for the purpose of proactively breeding for MLN while at the same time preventing movement of the disease from endemic areas. Personnel have been trained to safely conduct activities at the site. The facility operates under strict quarantine regulations and is closely monitored and approved by Zimbabwe’s Plant Quarantine Services to ensure that the maize materials introduced are MLN-free.
“This modern quarantine facility is expected to uphold safety when importing maize breeding materials to southern Africa, and to facilitate local and regional institutions to proactively breed for resistance against the MLN disease,” said Zimbabwe’s Minister for Agriculture, Mechanization and Irrigation Development, Joseph Made, while officially opening the facility.
Dr Made also said “I am confident that the quarantine facility will play a significant role in curbing the spread of MLN, while at the same time facilitating on-going work of developing new maize varieties that are resistant to the disease.”
“This MLN quarantine facility, and the collaborative efforts between institutions of the government of Zimbabwe, especially the Department of Research and Specialist Services (DR&SS) and CIMMYT-Southern Africa Regional Office, are key to prevent the possible spread of MLN in southern Africa, and to develop and deploy elite maize varieties with MLN resistance and other farmer-preferred traits,” said B.M. Prasanna, Director of the CIMMYT Global Maize Program and CGIAR Research Program MAIZE, while speaking at the same occasion.

CIMMYT and the government of Zimbabwe have so far conducted two nation-wide MLN surveys. In the first, no incidence of MLN was recorded. Results of the second survey are still being assessed. To strengthen the phytosanitary work at this MLN quarantine facility, CIMMYT will also offer capacity building to DR&SS researchers through trainings, technical assistance, and advisory services.
MLN is a reality that cannot be ignored. Partners have to work together to control its spread through finding practical solutions to tackle this complex challenge, including strengthening MLN disease diagnostic and surveillance capacity. In addition, intensive inter-institutional efforts to develop and deploy improved maize varieties that incorporate MLN resistance should be continued. The commercial seed sector must also play a key role by producing and delivering MLN-free healthy seed to farmers.
Until seed companies in the MLN-endemic countries have produced 100 percent MLN-free, clean commercial seed, and have necessary certification from the national plant protection offices, the potential risk of MLN entering southern Africa and the consequent damage to maize producers from significantly outweighs the benefits of commercial seed trade.
MLN can only be effectively prevented and tackled through concerted inter-institutional and multi-disciplinary action. The key actions include: enforcement of synchronized maize plantings and a maize-free period of at least three to four months in a year in severely affected areas; creation of an extension corps specifically dedicated to creating awareness on MLN management among the farming communities and monitoring and implementation of standard operating procedures for production of MLN-free clean seed at various points along the seed value chain, to be used by all players in the seed industry.
CIMMYT developed and released, through national partners in eastern Africa, nine MLN-tolerant maize hybrids in the last three years. Four among these hybrids are already being seed scaled-up and commercialized by seed company partners in Uganda, Kenya and Tanzania. As many as 19 MLN-tolerant hybrids are under national performance trials in eastern Africa.

EL BATAN, Mexico (CIMMYT) – Small-scale agricultural mechanization is showing signs it has the potential to fuel rural employment for youth in sub-Saharan Africa, according to researchers at the International Maize and Wheat Improvement Center (CIMMYT).
Across Africa, youth are struggling with high unemployment and working poverty, the International Labor Organization records. However, increased adoption of agricultural mechanization – especially machines that are small, affordable and easy to maintain such as two-wheel tractors – is stimulating jobs and entrepreneurial opportunities for African youth, said Frédéric Baudron, senior systems agronomist at CIMMYT.
“Small-scale mechanization is more equitable than other forms of mechanization as even the poorest and most vulnerable have access to it,” he said.
Youth, along with women, are typically subject to labor intensive farm activities causing them to shun agriculture. But with mechanization improving productivity while reducing drudgery, youth are seeing economic opportunity in agribusiness, on rural farms and as service providers, said Rabe Yahaya, a CIM/GIZ integrated expert specialized in mechanization for sustainable agriculture intensification.
As a result, new jobs along the value chain from mechanics to spare parts providers have been created, he added.
Relatively cheap and easy to operate two-wheel tractors can be used for many different applications. On-farm, the tractors are used to speed up crop establishment while conserving soils through reduced tillage and precision fertilizer application. They allow farmers to tap into surface water for irrigation as well as aid shelling grain to reduce the time taken to get to market. The machinery has also been used to start rural commercial hire and transport services.

24-year-old Beyene Abebe from Ethiopia is one youth benefiting from mechanization. Through CIMMYT managed training, Abebe has developed the skills needed to become a mechanization service provider. He now provides transportation services for an average of 200 households annually and ploughing services for 40 farmers in his village using two-wheel tractors. With the income from his service, Abebe can cover his family’s expenses and he bought farmland with his savings.
National government support for training and innovation is key to bolster agricultural mechanization throughout Africa, said Baudron. By creating a conductive business environment to attract private sector actors, governments can grease the wheels to scale out success.
Both Yahaya and Baudron shared some insights on the opportunities agricultural mechanization can provide rural communities in the following interview.
Q: Why is it important that agricultural research for development targets youth in rural areas?
RY: A growing population and diet change is increasing food demand in Africa, however, the amount of arable land is decreasing. This affects rural areas, where agriculture remains the main source of income and livelihood. Agriculture in the way it is currently practiced in rural areas is no longer attractive to the new generation of youth as it is labor intensive, rudimentary, risky, unproductive and does not support a good livelihood.
In addition, only 2 percent of Africa’s youth are undertaking agricultural curriculum at the university level. Despite young Africans being more literate than their parents, they suffer from increased unemployment. Agriculture could be the solution in tackling youth unemployment in rural areas, therefore providing peace, stability and food security.
FB: Youth unemployment is growing. Agriculture is perceived as a sector that can absorb much of this unemployment, particularly when combined with entrepreneurship.
In my view, an important issue when tackling issues of sustainable development as opposed to simply ‘development,’ is the issue of equity. We must ensure that the largest amount of people benefit from our interventions. Rural youth represent a large proportion of the vulnerable households in the areas where we work, because they lack capital and other resources, similar to women-headed households.
Q: How is mechanization creating new rural opportunities for youth and women?
RY: In many societies, youth and women are unequally disadvantaged and perform the most labor intensive agricultural activities such as plowing, sowing, weeding, harvesting, shelling, water pumping, threshing and transportation with very rudimentary implements using human and animal power. Therefore, increasing the use of engine power in agriculture will free youth and women from production drudgery discrepancies and most importantly increase farm productivity and consequently improve income generation if an organized value chain exists with a strong private sector involvement.
FB: Mechanization creates rural employment. It creates work for service provider jobs and it also stimulates other businesses along the mechanization value chains. Once demand for mechanization is established, employment opportunities grow for mechanics, fuel providers, savings and loans associations, spare part dealers, etc.
Q: What lessons are there to aid youth to be successful mechanization service providers?
RY: Training in mechanical, agronomic and business skills. Again training and constant follow up is key in order not only to produce successful youth mechanization service provider, but to ensure their continued success. In addition, infrastructure, aftersales — service and spare parts dealerships and financial schemes, promote the adoption of mechanization and support the development of value chain markets are crucial to success.
And remember whatever the technology may be, the farmer has to be able to earn money from it, otherwise they will not use it!
FB: Youth also tend to be better at managing modern technologies. We found consistently, in all countries where we work, that being a successful service provider is highly correlated to be a member of the youth. However, other factors are also important such as being entrepreneurial, educated, able to contribute to the cost of the machinery, and preferably having an experience in similar businesses and particularly in mechanics
Working with CIMMYT’s Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project, researchers have sought to promote the delivery and adoption of small-scale machines to make farming practices – including planting, harvesting, water pumping, shelling and transporting – more productive and sustainable in eastern and southern Africa. Funded by the Australian Center for International Agricultural Research, FACASI offers support throughout the supply chain, from importers to manufacturers, service providers and extension workers to ensure mechanization reaches farmers.
CIMMYT’s mechanization team has ongoing collaboration with GIZ/BMZ green innovation center in Ethiopia and works in Namibia with GIZ to provide knowledge, expertise and capacity building on conservation agriculture.

EL BATAN, Mexico (CIMMYT) – A comprehensive study of genetic gains resulting from long term breeding work on improved hybrids and open-pollinated varieties (OPVs) in eastern and southern Africa shows that with appropriate funding, maize yields can continue to increase in extreme heat and drought conditions.
Investments into maize breeding and seed systems must expand to keep up with the capacity to withstand climate variability in the region, said Jill Cairns, one of the authors of the study, emphasizing that maize breeding is on track to meet the challenges of climate change in Africa.
The region is currently experiencing large climate variability, including the 2014-2015 drought; the 2015-2016 El Nino and severe drought and flooding in 2016-2017.
“We see evidence that increased investment works,” said Cairns, a maize physiologist with the International Maize and Wheat Improvement Center (CIMMYT) in Zimbabwe. “Although our breeding work has led to higher genetic gains, yields remain lower, reflecting smaller research investments over time. On the other hand, in countries like the United States and China, which have become the top two maize producers worldwide, we see the beneficial impact of steady investments.”
Varieties released by CIMMYT’s partners in sub-Saharan Africa between the years 2000 and 2010, showed that genetic gains for yields made through this improved maize germplasm compare favorably with similar studies in other regions in better growing conditions — in China and the United States, for example.
On average, under optimal conditions, CIMMYT maize breeders increased yields by 109 kilograms per hectare per year, under managed drought conditions, 33 kilograms per hectare per year and under random drought conditions, 23 kilograms per hectare per year. By comparison, in China, under optimal conditions, gains were estimated at 95 kilograms per hectare per year and in the United States, 65 to 75 kilograms per hectare per year.
“Breeding is a long term investment but it ultimately pays off through improved varieties for smallholder farmers,” said Jill Cairns, a maize physiologist with CIMMYT in Zimbabwe, describing the impact of the breeding program in sub-Saharan Africa, which has been underway for more than 30 years.
“We’re constantly changing the breeding pipeline to ensure that the genetic gains are continuously increased,” she added. “Gains are illustrated by sustained increases in grain yield over time. In fact, we expect to see a higher genetic gain through the more recent hybrids developed by CIMMYT maize breeding team than those reported in the study undertaken on hybrids released between 2000 and 2010 because we’ve added a lot of new tools and we are incorporating many new technologies to further increase gains.”
The study confirmed that the lowest genetic gains occurred under low nitrogen conditions where little fertilizer was used, Cairns said, emphasizing the importance of increasing the potential for genetic gains to boost grain yields in areas with poor soil fertility throughout the region.
Scientists working with the CIMMYT maize breeding program primarily focus on developing hybrids, which result from the deliberate crossing of genetically diverse inbred lines that exhibit a wide variety of traits that are relevant for smallholders in the tropics.
Improved OPVs were developed at CIMMYT, using selected sets of inbred lines to reflect traits of the parental lines. In general, genetic gains in the OPVs released during the period under review were found to be higher than for the hybrids, although grain yields in the hybrids were certainly higher.
Resource-poor farmers in some African countries tend to use drought-tolerant improved OPVs, especially where the maize seed sector is weak or improved hybrid seeds are unavailable or unaffordable.
“Accessing hybrid seeds can be a real challenge for resource-poor, smallholder farmers in some areas,” Cairns said. “Hybrids also pose a conundrum for farmers in extremely drought-prone areas, where the tendency is to minimize the risk by using low-cost improved OPVs rather than investing in relatively higher-cost hybrid seeds.”
Yield gain in the CIMMYT-derived hybrids in eastern and southern Africa during the study period is comparable with gains reported in the United States and China. However, absolute yields in the region are still lower, reflecting the opportunity to further improve the yield potential of tropical maize, including in stress-prone environments.
Additionally, maize yields in sub-Saharan Africa, where maize accounts for 50 percent of cereal production in over 50 percent of countries, are still the lowest in the world. National maize yields in 30 countries in the region remain much lower than yields were in the U.S. Corn Belt in 1926 before hybrids were introduced!
Since the CIMMYT breeding program started in Zimbabwe in 1985 (part of the southern Africa region where maize accounts for 45 percent of calories and 43 percent of protein from cereals consumed), scientists have focused on increasing drought tolerance, among other important traits. Currently, the Stress Tolerant Maize for Africa (STMA) project operates in 11 countries across sub-Saharan Africa.
Continual evaluation is a critical component of crop improvement, according to scientists.
“Quantifying genetic gain each year is an integral part of our product development process,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program, and the CGIAR Research Program MAIZE. “This enables us to measure the progress being made, and to make necessary adjustments for continuous improvement of the performance of our products in the target agro-ecologies we serve.”
The research benefits are far-reaching.
In these two first-ever reviews evaluating genetic gains through CIMMYT’s maize breeding program in eastern and southern Africa, we get a clear understanding of benefits and impact of improved maize hybrids and OPVs released during 2000 to 2010, said Marianne Bänziger, who previously led the CIMMYT maize program, and is now deputy director general of research and partnerships at the organization.
“Use of improved seed has been increasing in sub-Saharan Africa and greater uptake is mostly a question of where the seed sector reaches,” Bänziger said. “The issue of variety replacement is complex. Working with governments and seed companies is a key part of our role.”
The dissemination and adoption of drought tolerant maize could generate as much as $590 million for farmers over a seven-year period, Cairns said. “As we take stock of the important role our work has played in this impoverished and environmentally harsh region, we’re grateful for the vital funding we receive from various agencies, especially the Bill & Melinda Gates Foundation, the U.S. Agency for International Development, and the CGIAR research program MAIZE.”

MEXICO CITY (CIMMYT) – CIMMYT doctoral student and ETH Zürich graduate Stephanie Cheesman has won the 2017 Hans Vontobel-Preis.
This ETH prize awards 5,000 Swiss Francs ($4,988) annually to the student with the most outstanding thesis in Agricultural Science. The prize is financed by a private fund set up in 1994 by the late banking doyen Hans Vontobel.
The thesis investigated the effects of conservation agriculture (CA) on maize yields and soil carbon stocks, as well as other plant nutrient stocks in the soil. It is based on data collected on 125 on-farm research sites CIMMYT had established between 2004 and 2009 in Malawi, Mozambique, Zambia and Zimbabwe.
The results showed that yields could quickly increase with CA, whereas soil carbon stocks showed – after up to only seven years of CA practice – limited response under the prevailing conditions of Zimbabwe. Farmers also generally adapt CA systems to their conditions rather than adopt the system, due to the fact that there are many more factors besides improved yields – such as preferences in crops grown, availability of inputs and access to other sources of income – that influence why a farmer adopts a technique.

The award panel consisted of Maja Baumann, granddaughter of Vontobel, Bruno Studer, professor and chair of the molecular plant breeding group at ETH Zürich and Sarah Springman, professor and rector of ETH Zürich.
Baumann cited Cheesman’s valuable hard data about conservation agriculture – a topic that has been strongly debated in recent years – and contribution to sustainable agriculture as main reasons for her selection. Further the jury appreciated that the thesis investigated both biophysical and socio-economic aspects, allowing for a better understanding of conservation agriculture’s impact.
Cheesman completed her thesis under the supervision of Emmanuel Frossard, professor at ETH Zürich, CIMMYT Senior Cropping Systems Agronomist Christian Thierfelder and Neal Eash, professor at the University of Tennessee. Professor Johan Six from ETH Zürich evaluated the work as external examiner.
“Stephanie Cheesman’s collaborative project between CIMMYT and the Swiss institutions funded by SDC highlights the strong interest of all organizations to extend sustainable agriculture intensification, with the aim of increasing food and nutrition security and eradicate poverty amongst smallholder farmers in southern Africa,” said Thierfelder.

Eastern Cape, SOUTH AFRICA (CIMMYT) – Smallholder farmers in South Africa can now access and grow new maize varieties with transgenic resistance to stem borers, the most damaging insect pest of maize.
Partners in Water Efficient Maize for Africa (WEMA) – a public-private crop breeding initiative that helps farmers manage the risk of drought and stem borers infestation in Africa –developed the genetically modified maize seed branded as “TELA,” which has been released and licensed royalty-free to South Africa seed companies for sale to farmers at affordable prices.
TELA – derived from a Latin word Tutela meaning “protection” – contains a gene from Bacillus thurigiensis (Bt) that helps the maize to resist damage from major stem borers to give farmers better yields. Five seed companies – Capstone, Jermat, Monsanto, SeedCo and Klein Karoo – are marketing the seed to smallholders.
The WEMA project is helping smallholder farmers face two of their chief menaces through the new insect protected and drought tolerant maize hybrids. Led by the African Agricultural Technology Foundation (AATF), WEMA brings together public and private partners including the International Maize and Wheat Improvement Center (CIMMYT), Monsanto and the national agricultural research organizations of Kenya, Mozambique, South Africa, Tanzania and Uganda.
Stem borers affect maize production on about 30 million hectares in developing countries, feeding aggressively on leaves, stems and ears and significantly reducing grain yield.
In eastern and southern Africa, two stem borers – Busseola fusca and Chilo partellus – are the most damaging pests. In South Africa, reported annual yield losses in maize range between 10 and 75 percent. Yield losses in maize and sorghum as a result of Chilo partellus have exceeded 50 percent.
During the last 2016 planting season, Nontoko Mgudlwa was one among the selected smallholders to host a trial for TELA maize hybrid.
“I received a small packet of TELA from our extension officer, and planted it in this small portion of land on December 9, 2016,” said Mgudlwa. “The land was not enough to add my indigenous maize, but I’m very happy to see how the crop is performing despite the very visible attack on the border crop by stem borers,” continued Mgudlwa, pointing out the severely damaged border crops that were planted with refuge seed as a control group alongside TELA.
TELA maize (left) in Mgudlwa’s farm showed good resistance to stem borer infestation, whereas plants in the refuge plot of non-TELA maize on the same farm show the shot holes typical of stem borer feeding. Photo: B.Wawa/CIMMYT
The farmers who hosted trials were given a 2 kilogram packet of TELA maize as part of demonstrations to raise awareness about the variety and help farmers see its performance. The packet also contained a small pack of seed of non-Bt maize called “refuge” seed to sow at the border of the main plot. This non-Bt maize allows the survival of susceptible borers and thus delays the emergence or spread in borer populations of individuals able to overcome the Bt maize resistance.
Mgudlwa’s home in Nqatu Great Palace suffers frequent borer infestations, which most farmers control using insecticides. As part of the trial, Mgudlwa did not use chemicals despite a heavy invasion of the pests on her farm and evidence of significant damage in the refuge crop.
“It is critically important for farmers to understand the requirement and procedure of planting TELA maize and the refuge seed found in a small bag inside the TELA seed pack,” said Kingston Mashagaidze, WEMA project coordinator in South Africa. “The extension officers have been trained on how to plant TELA and the refuge seed, so they can help farmers to plant the crop the right way.”
Recently, Mozambique joined Kenya, Tanzania and Uganda to successfully conduct confined field trials (CFT) for genetically modified maize. The CFTs are important to generate data on the performance of the Bt maize and commercial conventional hybrids infested by stem borers to support the application for the release of TELA hybrids in the remaining four WEMA countries.

EL BATAN, Mexico (CIMMYT) — In a special interview to mark International Women’s Day, International Maize and Wheat Improvement Center (CIMMYT) gender and development specialist, Rahma Adam, detailed how her research aims to improve the agricultural productivity of women in southern and eastern Africa.
With women making up over 50 percent of farmers in many parts of Africa, it is essential to understand how gender roles, relations and responsibilities encourage and hinder their agricultural productivity, said Adam.
Understanding gender relations improves the work of researchers and development specialists to target programs in the correct areas and with right people in order to get the most impact, she said.
Conservation agriculture systems involve crop rotations and inter-cropping with maize and legumes to increase yields. Pictured here are conservation agriculture practitioner Lughano Mwangonde (L) and gender and development specialist Rahma Adam in Balaka district, Malawi. Photo: CIMMYT/Johnson Siamachira.
Sustainable intensification agriculture practices are aimed at enhancing the productivity of labor, land and capital without damaging the environment. In practice, sustainable intensification involves such conservation agriculture practices as minimal soil disturbance, permanent soil cover and the use of inter-cropping and crop rotation to simultaneously maintain and boost yields, increase profits and protect the environment. It contributes to improved soil function and quality, which can improve resilience to climate variability.
Through SIMLESA, supported by the Australian Center for International Agricultural Research (ACIAR), Adam shares her findings with a network of stakeholders, such as governments and non-governmental organizations, aiding the delivery of agricultural technologies, taking into account gender norms to hold a greater chance of adoption.
We spoke to about her work in a short interview listen here or read below:
Q: Please explain a bit about your work. What is SIMLESA, where does it operate and what are its key objectives?
A: SIMLESA stands for, Sustainable Intensification of Maize and Legume Systems for Food Security in Eastern and Southern Africa, we are now in the second phase of the project. We focus on several things, providing the needed knowledge in terms of technology, improved varieties of seeds for maize and legumes and how to use them in the practice of sustainable intensification practices. The idea is to improve crop yields from current levels, that’s the basic idea of SIMLESA.
The project operates in mainly five countries, Tanzania, Kenya, and Ethiopia for Eastern Africa and Malawi and Mozambique for southern Africa. But we have three spill over countries where SIMLESA also have some activities, they are Rwanda, Botswana and Uganda.
We want to make sure farmers know the practices of sustainable intensification, they are able to use them, able to adapt them for the benefit of improving food security of the household and increase their livelihoods.
Q: Why is gender analysis important in meeting SIMLESA’s objectives?
A: Women in sub-Saharan Africa play a lion’s share of farming, the literature shows on average they farm as much as men, they make up 60 percent of farmers or more in some countries. Because they are the majority, there is no way we could put them on the back-burner, and not address or try to understand what are their constraints for agricultural production and agricultural marketing and all the other things that go with an agricultural household being successful in terms of their livelihoods.
It is very important to think about women, not alone, but also their relationships with men, we also have to think about who are their husbands. In sub-Saharan Africa most households are patriarchal, so they are male dominated, meaning a husband has much more say than the wife in terms of decision making in regards to what to grow, how much money should be spent that they have collected from agriculture, among other things.
It is important to not only think about how to improve the lives of women but also to understand the norms that go on. The institutional norms within a community, within a household and how they can play some sort of role that can either make a women successful or make a woman unsuccessful in terms of bringing up her household, in terms of the betterment of nutrition and schooling, etc.
It is a very complex issue. That’s why we cannot ignore gender itself as it sits in the rural households of Africa, because it is the nucleus of it. Once we understand how the relationship works between husband and wife or man and woman working within a society then we will be able to say how we can really propel sustainable intensification in these communities.
Q: Although rural women in southern and eastern Africa play crucial role in farming and food production why are they less likely to own land or livestock, adopt new technologies, or access credit?
A: Most of the problem of women’s lack of ownership of assets, such as land, among others stems from the institutional social norms of the communities in which they reside. Usually for patriarchal societies in sub-Saharan Africa, women are married into their husband’s home, and thus nearly all assets including land, livestock, improved or new technologies and money belong to their husbands and in some occasions, wives have very little say, with regards to those assets.
Because the major assets of the households are under the hands of the husband, it is hard for the wife to be able to access credit facilities, without involving the husband. As most of the credit and financial facilities, require a collateral, before they provide one a loan.

NAIROBI, Kenya (CIMMYT) – Africa’s agriculture sector is driven by smallholder farmers who also account for 70 percent of people directly reliant on agriculture for their livelihoods. Despite its large-scale impact across the continent, smallholder farming largely remains a low technology, subsistence activity.
Constructively engaging smallholders as investors as well as producers can help attract better investment into the sector, engaging farmers to produce bigger crops for sale rather than only for consumption at the household level. To achieve this goal, bigger financial investments are required to raise the standard of engagement and consequently that of Africa’s agricultural sector, according to Paswel Marenya, a social scientist who works with the International Maize and Wheat Improvement Center (CIMMYT),
Three recent studies conducted by CIMMYT scientists and their collaborators in eastern and southern Africa assessed potential interventions to address current inefficiencies in seed supply chains. They also explored how low purchasing power has hobbled smallholders trying to gain access to maize and legume seed markets. Even though these markets have recently expanded as more private companies invest in maize and legume businesses, smallholders have not benefited despite their significant role in the sector.
A key component of improving agricultural practices is to bolster seed systems to give smallholders better access to high-yielding, stress tolerant seeds. For example, in Tanzania, a weak seed supply chain led to smallholders recycling hybrid maize seeds up to three years in a row in some cases. The main source of legume seeds was often from seed saved from previous harvest.
Elsewhere, in Mozambique, smallholders surveyed were accessing only three improved varieties in 2014 despite the release of over 30 improved maize and legume varieties that year. In a country where 95 percent of the population is dependent on maize and legumes, which particularly for rural families provide the most important source of proteins, deep changes are needed to facilitate access to improved seeds.
The studies determined that ineffective seed distribution contributed significantly to limiting smallholder access to improved varieties. Additionally, low seed production from the few approved seed companies in the country has worsened the situation due to soaring costs, putting improved seed beyond the reach of millions of smallholders.
As a result, approximately 70 percent of Mozambican farmers use local maize varieties with poor resistance to pests and diseases and low productivity potential.
To address these issues, the studies unanimously recommend investments in rural roads to connect isolated communities with agricultural and seed markets and to make it more cost effective for seed distributors to reach far flung communities. Secondly, investments in storage facilities in Mozambique and a more effective national seed system are needed to facilitate adequate foundation seed for seed companies. In addition to favorable policies that attract more private seed and fertilizer companies, a stronger public agricultural extension system is required.
On a broader scale, government policymakers must take advantage of the burgeoning seed sector and mushrooming interest from private sector players.
“Regulatory agencies in the seed sector should take up a bigger role to facilitate and encourage competition that will widen seed access and bring down seed costs,” Marenya said. “This is the most sustainable solution that ensures the private sector is involved, farmers drive seed demand, and profit prospects are good.”
Rising food demand and projected growth of African food markets present a real opportunity for African farmers, Marenya added. In 2011, for example, sub-Saharan Africa imported $43 billion worth of such basic agricultural commodities as wheat, rice, maize, vegetable oil and sugar. Additionally, research estimates from Germany’s Deutsche Bank show that urban food markets will quadruple and that food and beverage markets are projected to grow to about $1 trillion by 2030 leading to bigger economic benefits overall.
While staple crop markets in the eastern and southern Africa region are relatively vibrant, many farmers gain access to these markets through informal links. Structured value chains, which include dependable and transparent information systems, quality storage facilities and supportive financial or credit services would enhance farmers’ role in the markets.
“Real change will occur when efforts be made to enable farmers and traders to profitably invest in superior pre- and post-harvest quality management as well as engage in contract-based supply chains to exploit opportunities brought about by increasing urbanization and trade,” Marenya said.

HARARE, Zimbabwe (CIMMYT) – Little did 47-year-old Thokozile Ndhlela know that growing up in a rural area in Zimbabwe would inspire her to become a well-respected agricultural scientist, helping to transform agriculture by developing science-based solutions to some of the complex issues facing African farmers.
Currently a postdoctoral staff member with the International Maize and Wheat Improvement Center (CIMMYT)in Zimbabwe’s capital Harare, Ndhlela encourages girls to choose options that lead to careers in agriculture. Most farmers worldwide average an age of over 60, so Ndhlela’s work is also helping to encourage young people to get involved in agriculture.
“There are many exciting opportunities to further improve agricultural productivity and improve food and nutritional security in my country, and beyond,” she said with a chuckle.
She comes from humble beginnings – growing up on a small farm, through primary and secondary school, and universities – and now she has begun to reap the rewards of her hard-won endeavors.
She credits her farmer father as her inspiration to pursue agricultural science.
“My father was my greatest source of inspiration for me to venture into agriculture,” Ndhela said. “From high school, he encouraged me to study sciences. He used to boast, saying his daughter would be studying agriculture and that I’d come back and assist him in his plot.”
His dream came true.
“I’m proud now since he is growing improved maize varieties that l’m providing him,” she said, adding that he proudly tells his friends that the varieties are being bred by his daughter.

For Ndhlela, the journey has at times been long and winding. She has had to burst age-old stereotypes, which doubt women’s capacity to engage in science and balance career aspirations with family commitments. She started her journey in pursuit of her first desire to become a teacher, but, she changed course to become an agricultural scientist.
She believes making agricultural research a high priority will also attract more skilled professionals to the field — especially women and young people.
“I’m happy to see farmers in my region using results of my research work,” she said.
Her scientific ambition was nurtured by her female secondary school teachers. After finishing secondary school in 1989, she enrolled at Gwebi College of Agriculture outside Harare to study for a national diploma in agriculture. Afterwards, she worked at the Zimbabwe Crop Breeding Institute in the Ministry of Agriculture’s Department of Research and Specialist Services (DRSS). While at DRSS she earned her Bachelor of Science in agriculture at the Zimbabwe Open University and subsequently enrolled for a master’s degree in plant breeding at the University of Zambia. While at the DRSS, she began her research and earned a doctoral degree at the University of the Free State in South Africa in 2012, with a thesis entitled, “Improvement strategies for yield potential, disease resistance and drought tolerance of Zimbabwean maize inbred lines.”
“My greatest passion is to see farmers in Zimbabwe and beyond grow improved maize varieties to step up food security and improve their livelihoods,” she said. “After becoming qualified, I was thrilled to put my skills to work and worked hard in breeding maize for drought, disease, heat and other stresses.”
Ndhlela has had the good fortune to implement the results of her work. While working for the national research system, she led the crop breeding program and won CIMMYT’s Best Breeding Program Award in southern Africa five years in succession. This success later culminated in winning the Zimbabwe Presidential Award for excellence in agricultural research in 2015. Under her guidance, the program saw the release of seven high yielding, drought tolerant hybrids and two open pollinated varieties in five years.
“This was no easy feat since it involved a lot of hard work, tolerance,” Ndhlela said. “I used to spend most of the time in the field since plant breeding is done in the field, and not in the office.‘’
CONFRONTING CHALLENGES

In Africa, food and nutritional security remain a major concern. Declining soil fertility is a significant issue in the region, leading to poor crop performance. Climate change could also result in the number of malnourished people in sub-Saharan Africa increasing by 40 percent by 2050 – from 223 million to 355 million people, according to the Alliance for a Green Revolution in Africa. This challenge will require a great deal of innovation and focused scientific effort.
Ndhlela said smallholder farmers should shift agriculture from its current largely informal status in the economy into the formal business sector with a more structured system that targets young women. As a result, women in agriculture will play critical roles in agricultural incomes and employment development. When treated appropriately, added Ndhlela, agriculture can be moulded into an attractive career, especially for youth. In addition, she said, Africa needs more scientists, and especially women scientists.
A mother of four boys, Ndhlela believes she can make a difference to people’s lives through her agricultural research in development work. She shares her views on women in agricultural research in the following interview.
Q: Tell us about your early childhood.
A: I was born in Matobo District in Matabeleland South province of Zimbabwe. I’m the second born in a family of three boys and two girls. I spent most of my early childhood with my paternal grandparents in Matobo rural area. My grandparents earned a living off farming, growing horticultural crops commercially. They were passionate about farming, and l remember when l was in Grade One I would be woken up very early to go and work in the field before going to school. After school, or during weekends, l would also take the responsibility of herding goats. My parents were also passionate farmers and during school holidays we would all help my grandparents with farm work.
Q: What was one of your childhood dreams?
A: My childhood dream was to become a teacher. I was being inspired by my parents, and my many relatives who were in that profession.
Q: Was there any particular female scientist who inspired you when you were at school?
A: I was particularly inspired by my high school biology and chemistry teachers, who were both female. They taught me that what boys could do we girls could do too.
Q: “Girls should not believe that science training at university is a male domain.” What’s your comment on this?
A: Girls used to shy away from science especially at college level but with the new generation this seems to have changed as more girls are now doing science- based programs.
Q: Role models are also critical in shaping one’s future. Who was your inspiration to pursue a doctorate in agriculture?
A: Dr. Marianne Banziger, CIMMYT deputy director general for research and partnerships (then leading CIMMYT’s Global Maize Program, based in Kenya) inspired me to pursue doctorate studies. Doing a doctorate was far-fetched for me until Dr. Banziger asked me if l were interested in pursuing doctoral studies. She assured me that CIMMYT would support me secure a place to study.
Q: There’s a general misconception that studying agricultural science only prepares one to work on a farm. Is this the case?
A: This misconception used to be there especially when l was studying for my national diploma. We would play sports with students from other technical colleges whose students would snear at us agriculture students. They thought we could only work on a farm. Even my high school friends never understood why l chose agriculture. They asked me whether l would be able to work on a farm. But this is changing. People are now aware of the opportunities in agricultural science. I have personally had encounters with parents asking me what is required for their children to study agricultural science. I have made a career in science and agriculture and young girls can do it, also.
Q: Tell us about your experiences as a female researcher with DRSS. What does it mean to a female researcher? What are your experiences at CIMMYT?
A: As a female researcher at DRSS, I commanded a lot of respect from both male and female counterparts. This inspired and gave me the zeal to keep aiming higher. I started working at DRSS in 1994 as a diploma holder. With encouragement and inspiration, l ended up with a doctorate in plant breeding.
At DRSS, I led the Crop Breeding Institute to win a national award in maize breeding excellence. Called the “Robert Gabriel Mugabe Award” (after the Zimbabwean president), it is presented bi-annually for critical breakthroughs in research. The $15,000 award was presented to the Crop Breeding Institute’s National Maize Breeding Program, for outstanding research in the production and release of the maize variety ZS265. The variety has excellent tolerance to diseases, drought and low nitrogen and therefore suitable for production under dryland conditions.
In recognition of their sterling effort in using plant breeding to address low maize productivity on smallholder farms, CIMMYT’s Drought Tolerant Maize for Africa project awarded the “Best Maize Breeding Team in southern Africa” prize to Zimbabwe a record five times from 2008 to 2014.
Food insecurity can be overcome if we can bring together new knowledge and skills to farmers in a very sustainable manner. There will be crop production challenges unless we integrate climate change, soil fertility and water.
Joining CIMMYT as a maize breeder in 2014 was a dream come true for me and l really felt rewarded for my work. As plant breeding is male-dominated at CIMMYT- Southern Africa Regional Office, l feel challenged to do even better and prove that even women can do the job. I believe I’m an inspiration to other upcoming female scientists.
Q: During training, what was men’s attitude toward you?
A: I used to command respect from some of my male colleagues. However, some would look down on me. These were forced to change their attitude once they realized that I was better than them in our studies. I vividly remember such a scenario at the University of Zambia where l was the only female in a class of 10 Master of Science students.
Q: What was the main output of your agricultural research?
A: The main output of my agricultural research was the successful production of hybrids that are high yielding, drought and disease tolerant.
Q: To what extent are you involved in agricultural innovation at CIMMYT?
A: I’m particularly working on a special program on pro – vitamin A maize. This research work is both challenging and rewarding as my colleagues respect me because of my achievements. The work seeks to alleviate the problem of vitamin A deficiency that is prevalent in most developing countries, including those in southern Africa. There is very good evidence that vitamin A deficiency leads to an impaired immune system and can even have an impact on brain development. But effective science can make a huge difference here by enriching staple crops such as maize, with pro-vitamin A and providing subsistence farming households with nutritionally enhanced food.
In Zimbabwe, nearly one in every five children under the age of five years are vitamin A deficient. These deficiencies can lead to lower IQ, stunting, and blindness in children, increased susceptibility to disease for both children and adults; and higher health risks to mothers – and their infants – during childbirth. In partnership with HarvestPlus, and other fellow CIMMYT scientists, l have managed to facilitate the research and release of four pro-vitamin A hybrids in Malawi, Tanzania (two), Zambia (six) and Zimbabwe (four).
Q: Has working for CIMMYT in maize biofortification enriched your skills and knowledge?
A: Working at CIMMYT has made me grow in science. Coupled with improved leadership and gradual increase in my communications skills, I have become very confident in my career. Before joining CIMMYT, I had less knowledge on maize biofortification. I have since gained a lot of knowledge so that l can now explain to people what l’m doing with so much confidence and enthusiasm. I’m loving it!
Q: Women face huge challenges daily and often lack the right kind of support. The employment environment can also be hostile to women scientists. Has working for CIMMYT enabled male scientists to view female scientists the same, as equal partners in agricultural research in development?
A: I feel male scientists at CIMMYT are mature and view female scientists as equal partners in agricultural research in development, and l respect them for that.

LIRA, Uganda (CIMMYT) – Sam Olum started commercial maize farming three years ago in Lira District, situated approximately 340 km north of Uganda’s capital, Kampala.
As an out-grower, Olum owns and manages 25 acres of land, which he has been planting with hybrid maize for sale to seed companies. He was able to earn more profit using hybrid varieties, which yield more, and put this money into his microfinance business – Aninolal Investment Ltd.
A large number of seed companies in Africa use out-growers, also known as contract farmers, who ensure there will be supply for the companies’ agricultural products. Out-growers produce seed on their own land under contract with the seed company, and are guaranteed purchase of the produce.
Olum first came across hybrid maize two years ago when his uncle Gilbert Owuor introduced him to Otis Garden Seed Company that produces and markets improved drought tolerant varieties WE2114, WE2115, UH5051 and Longe 7H. Olum decided to invest his entire 25 acres of land on WE2115, and hasn’t looked back since.
“I have faithfully planted this variety for two years since it got into the market and the amount of yield I harvest each season is worth the money put into this work,” said Olum. Every season he planted WE2115 his farm was filled with at minimum 350 bags of 120 kg each.
His biggest praise for this variety is that it matures fast, the cobs are big and it is high yielding. In addition, given that Otis Garden Company provides Olum with a ready market for his produce, he is guaranteed a stable income that has transformed him into a successful businessman.
Returns from the WE2115 yield have enabled Olum to bolster his microfinance business that is now worth UGX 200 million (approximately $55,000).

“The profits from this variety have made a very big difference in my business,” Olum said. He has expanded his clientele beyond his hometown and now reaches farmers from other districts. “At the moment we loan out between 50 and 80 million shillings ($ 14,000 and 22,000) to about 200 farmers in Amolatar, Dokolo, Lira, Masindi and Oyam,” added Olum.
The interest of eight percent he charges on the loans is quite affordable for many farmers compared to the interest rates charged by other financial institutions that range from 12 to 15 percent. Besides supporting farmers, Olum has created job opportunities for 15 people employed full time at his company.
WE2115 and other similar varieties are marketed under the brand name DroughtTEGO, currently grown in four other countries in Africa (Kenya, Mozambique, South Africa and Tanzania). In 2016, Uganda’s national variety release committee approved the release of an additional four DroughtTEGO varieties: WE1101, WE3103, WE3106 and WE3109, expected to get into the market by 2018.
