In recent years, CIMMYT’s collaboration with partners in the South Africa Development Community (SADC) has flourished in scope and strength to span research, training, and shared experiences with researchers, extension workers, farmers, seed companies, and four national universities. The various parties bring their strengths to this alliance, resulting in synergy and a fluid transfer of impact-oriented technologies and knowledge to smallholder farmers.

From the Ivory Tower to Farmers’ Fields

Mick Mwala’s friends have nicknamed him “Dr Mobile.” On any given day he can be found at any of three or more places: the lecture halls and laboratories of the Department of Crop Science at the University of Zambia (UNZA), interacting with his students at the CIMMYT-Zimbabwe research station, or in the field visiting smallholder farmers who host “baby” trials in farmer-participatory maize variety evaluations (popularly known as mother-baby trials ) throughout the SADC region. Occasionally, he will also call on the offices of local seed companies to chat about the varieties being tested in the field. The only way to reach Mwala on weekdays is via his mobile phone, hence the nickname.

Mwala, a Senior Lecturer at the University of Zambia (UNZA), is among the many individuals who supply impetus to agricultural progress in the region. Since 2000, he has been allocating 30% of his time to providing regional leadership within CIMMYT’s southern African research agenda. “I advise national research and extension staff in 10 southern African countries, each of them leading a network among farmer and partner organizations to identify new maize varieties suitable to smallholder conditions,” he explains. Marianne Bänziger, director of CIMMYT’s African Livelihoods Program, sees Mwala’s secondment to CIMMYT as one approach to an extremely productive collaboration between an international agricultural research center and the present expertise of African universities, and Mwala concurs.

“Many universities had become ivory towers, with little actual connection to the development issues their research and training activities should address,” he says. His focus on CIMMYT has involved him in a highly relevant, cooperative effort allowing CIMMYT’s state-of-the-art science and technologies—such as new breeding approaches for drought tolerance, or GIS tools—to be utilized. “The experience has definitely cross-fertilized my approach to teaching at the university and equipped me with a developmental perspective towards training and research,” Mwala says. The expanse of collective knowledge is also shared among international agricultural research centers, national agricultural research systems (NARS), non-governmental and community-based organizations, church-based groups, schools, the private sector, and with individual smallholder farmers. In turn, CIMMYT has gained much from Mwala’s experience in capacity building and his intrinsic knowledge of southern Africa and its people.

New Challenges Add a New Dimension to Collaboration

For many decades, agricultural research institutions have grappled with how to design variety release systems that are more responsive to smallholder farmers’ needs. Farmers’ access to seed must be improved, especially for those who have to travel long distances. By partnering with institutions possessing broad and in-depth knowledge of the southern Africa region, its people, cropping systems, and technology transfer approaches, international centers such as CIMMYT are better able to deliver innovative science-based solutions for improved livelihoods.

A troubling phenomenon that Mwala has observed in the course of his work is the extremely high staff turnover rate in the region’s NARS. “It is not unusual for the staffing profile of an institution to completely change in a given year, and this presents a tremendous challenge to agricultural development,” he states. Bänziger estimates that half of the maize breeders in southern Africa leave their posts within three years, and she notes, “This is less time than is needed to identify a variety for release to farmers.” Staff trained in the 1980s are approaching retirement or have already done so

In addition, most staff joining NARS come only with a fresh BSc degree, and the experienced people are involved in management rather than research or have moved to greener pastures. In recent times, many succumb to illness, ranging from preventable diseases like malaria to terminal conditions like HIV/AIDs. Donor investments in graduate training have decreased to the extent that few universities in the region can maintain viable MSc programs.

To address these issues in a more coordinated fashion, Mwala, in collaboration with CIMMYT, obtained support from The Rockefeller Foundation in 2003 for MSc training of NARS scientists at the University of Zambia. Six scientists are completing their research projects at four international centers in the region—CIMMYT, ICRISAT, CIAT and IITA/SARNET —following a year’s course work at university.

Dibanzilua Nginamau, one of the Rockefeller-supported students, says, “I could never have done an MSc degree in plant breeding in Angola, because my country does not have a postgraduate program in that field. While at UNZA, I met colleagues from Zambia, Mozambique, and Tanzania who, like me, were breeders confronted with a tremendous responsibility and no postgraduate education.” The course work at UNZA coupled with his applied research at CIMMYT has equipped Nginamau with the skills, competence, and confidence to breed successfully for Angola’s needs. “I can now lead my own breeding program back home!” he says.

Gaining from this network are farmers, scientists, NARS, universities and their students, as well as organizations like CIMMYT. Building on relationships and working together is essential for smooth transfers of knowledge to the farmers. It is also more cost-effective. “Working together actually required fewer resources than if we had all gone down the path on our own,” Mwala concludes.

Mzuzukuru and Sekuru may not be real people, but these two new faces will help teach extension workers and farmers about growing open-pollinated varieties (OPVs) in Zimbabwe.

In a brightly colored, cartoon-style booklet published in March 2004 by CIMMYT-Zimbabwe and Agricultural Research and Extension in Zimbabwe (AREX), these fictional characters examine maize and chat in the field about the benefits of OPVs.

“Young man, I’ve been watching your fields for some time,” the older Sekuru says at the beginning of the booklet. “Your maize is growing well. What’s your secret?” His query sets off a series of questions and explanations with Mzuzukuru, who relays how he grows a drought-tolerant, well-adapted OPV.

The booklet’s creators, Peter Setimela and Marianne Banziger from CIMMYT-Zimbabwe along with Xavier Mhike and Patience Nyakanda from the National Agricultural Research System in Zimbabwe (AREX), initiated the booklet after attending a workshop about successful community-based seed strategies. There they learned that many NGOs and extension workers did not know the difference between OPVs and hybrids, says Setimela.

In response to this lack of information, the group decided that a simple and entertaining picture book would be the best way to educate people about the issue. It could answer common questions in terms that are accessible for everyone.

The collaborators hope the booklet, titled “Improve Your Maize Harvests: Grow Certified Seed of Open-Pollinated Varieties,” educates extension workers, NGOs in seed distribution, and farmers in the Southern African Development Community (SADC) about seed recycling and the differences between hybrids and OPVs.

Setimela would even like children to be able to understand the booklet, which uses non-technical language, and bring it to their parents. “It provides simple scientific information that non-scientists can understand and apply,” he says. “And now extension workers can pass the information on to farmers.”

In the booklet, the younger Mzuzukuru corrects common misconceptions about differences between hybrids and OPVs. For example, although planting recycled hybrid seed causes lower yields, he says, farmers can recycle OPV seed for one or two seasons without much yield loss. He also clarifies that while hybrid seed is suitable for productive fields, OPVs are better for poorer fields.

Mzuzukuru also explains that maize varieties can mix when they grow near each other. To keep a variety pure, farmers should plant certified seed that is recommended for that area, isolate the crop from other varieties, inspect the field before flowering, and remove any dissimilar plants. He says that certified OPV seed is produced under strict guidelines to avoid contamination.

Setimela says the predominance of hybrid seed on the market in southern Africa has led to the dearth of knowledge about OPVs. Most farmers in the SADC region have limited access to improved seed and end up recycling seed that has been exhausted after many years of planting. This practice can perpetuate low yields and food insecurity. However, Setimela expects the trend to change as many NGOs and farming communities have become interested in new stress-tolerant OPVs that were developed in southern Africa.

Picture books can be very effective teaching tools, according to CIMMYT maize breeder Kevin Pixley. In Bangladesh, he saw flipcharts about activities such as seed production that paired the local language with cartoon-type drawings to use in farmer discussions. Pixley understood the message through the drawings, even though he could not understand the words.

“The temptation is to make it too complicated, and also the temptation is to do it from the scientists’ perspective,” says Pixley, who thinks the best strategies are developed with farmer input. “Unless you involve farmers in developing the messages, you’re not going to end up with something that is as good as it should be.”

The OPV booklet will soon be available in other languages. The national maize breeder in Mozambique is going to translate it into Portuguese, and the head of Zimbabwe’s crop breeding institute wants it translated into Shona and Ndebele. It may be translated into other southern African languages, as well. Feedback on the OPV booklet will help everyone revise it to improve its effectiveness.

At the booklet’s end, Mzuzukuru and Sekuru shake hands, just as they do at the beginning. Extension workers and farmers will probably share Sekuru’s final conclusion: “Thanks for your advice!”

CIMMYT’s External Program and Management Review (EPMR) is underway. Seven members of the EPMR came to El Batán from 22-26 November to commence the meetings and evaluations, which will be continued in its main phase from 14-25 February 2005. The fifth review of this kind for CIMMYT, it is the single most important mechanism by which a CGIAR center’s science and management achievements are assessed. Under the microscope for this process are CIMMYT’s mission and strategy within the CGIAR system, its scientific significance and quality, management effectiveness, and impact of activities.

Initial discussions were on governance and began in October, when three of the review members met with the Board at their last meeting. During the November meetings, many of the reviewers met with research and discipline program members in person, over the phone or via video links. On the agenda were topics such as maize and wheat breeding, natural resource management, and economics. The results of the review will be presented to the CIMMYT Board 14-18 March 2005, and then to the Science Council from 4-8 April 2005. Panel members are:

Chair: Don Marshall (Australia) – wheat breeding and biotechnology
Peter Goertz (Germany) – maize breeding and biotechnology
Shu Fukai (Japan) – natural resources management
Eugenio Cap (Argentina) – economics
Maureen Robinson (USA) – governance
Edward Sayegh (Lebanon) – management and finances

The CIMMYT-convened Rice Wheat Consortium for the Indo-Gangetic Plains (RWC) reaches out to the poorest of the rural poor in India’s Bihar state.

Mrs. Lal Muni Devi and her family live in a windowless, single-room, thatched roof house in the village of Azad Nagar, half an hour’s drive from the city of Patna in Bihar state in India, in the impoverished eastern section of the vast Indo-Gangetic Plains. Most farms here are small and almost all farmers grow two crops a year; rice during the wet, monsoon season, and wheat on the same fields during the dry winter. The RWC conducts farmer-managed trials and demonstrates practices that conserve soil quality and water and cut farmers’ production costs. These include direct seeding of wheat and rice without previously cultivating the soil—a practice known as zero-tillage. In the case of rice, this involves the radical measure of growing it on dry land; that is, without flooding fields or puddling the soil.

But there’s a catch: Devi is not a farmer. She and her family are among the landless poor who cannot directly benefit from the new, resource-conserving practices that are starting to make a difference for smallholder farmers in her community. In fact, what little income she and her family earn comes from selling their labor to the farmers. They prepare the land for rice, for example, and transplant the rice seedlings from nurseries to the paddies. They also weed the wheat fields and harvest the crops, all by hand.

Providing opportunities for people like Devi is one part of an RWC project being implemented in partnership with the Indian Council for Agricultural Research (ICAR) and supported by the International Fund for Agricultural Development (IFAD) in the district. “The landless are typically the core rural poor”, says Olaf Erenstein, CIMMYT socioeconomist in South Asia. “But they are relatively invisible, difficult to reach, and often forgotten by agricultural research and development organizations. The challenge is to provide them with significant income-generating options by building on their skills and the limited assets they command.”

Devi’s house is lit only by small kerosene lamps. Inside, balls of wheat straw hang on twine from the roof. Oyster mushrooms grow on each ball, thriving in the relatively dark and damp interior of the house. There is a market for them in the nearby city and wheat straw is plentiful. The spores are readily available and, at 50 rupees a bag (the equivalent of about US$ 1.20), not expensive. The economics are good and the mushrooms don’t require much labor.

“I’ve just sold my first kilo and received 250 rupees,” she smiles, happy at the prospect of having cash for household needs. In Azad Nagar, women have formed a self-help group and are all growing the mushrooms, a proficiency they acquired through the project

This is the first season and the group represents a small, pilot initiative, but the impacts are already being felt. “Now we have tasted the delicacy ourselves, the oyster mushrooms, for the first time,” Devi says. The women recognize new bonds among themselves in their community and control the money they earn. “I need to buy some new clothes for the family,” Devi says. “And if there is something left, I want to buy some jewelry.”

A new study reports on the extensive use and benefits of CIMMYT wheat.

The advantage is clear: the use of CIMMYT wheat creates enormous benefits for those who grow them. Even by conservative estimates, every US $1 invested in wheat research by CIMMYT generates at least US $50 for those involved in growing CIMMYT-related wheats. According to the publication, Impacts of International Wheat Breeding Research in the Developing World, 1988-2002, farmers sowed CIMMYT-improved varieties on 62 million hectares in 2002.

“This report reaffirms the major contributions of CIMMYT wheat around the world, including areas of smallholder, resource-poor farmers,” says John Dixon, director of CIMMYT’s Impacts Targeting and Assessment Program. Farmers in developing countries yield 14 million more tons of wheat per year because of international wheat breeding research. In addition, 80% of wheat grown in developing countries has CIMMYT wheat in its family tree.

Because this report documents the successful adoption of modern wheat lines, policy-makers will be able to assess progress and set priorities for future research investment. Its conclusions support those found in two earlier studies, and the coverage extends to include many countries in Eastern Europe and the former Soviet Union.

In countries such as Argentina, Brazil, Chile, and Uruguay, more than 75% of wheat marketed by private companies has CIMMYT ancestry. Widespread adoption of CIMMYT lines reflects the extensive use of partnerships and networks with other breeding programs to reach farmers with relevant varieties. This adoption and the subsequent higher on-farm yields generate enormous benefits for farmers, enhancing their food security and livelihoods (see box)—a central part of CIMMYT’s mission.

CIMMYT-Nepal makes progress against a disease in wheat that disguises itself as drought.

CIMMYT and partners in Nepal have identified new sources of genetic resistance to a disease that makes wheat plants looks as though they have been through a drought. The symptoms of foliar blight result from fungal infections, either spot blotch or the less well-known but related tan spot. These pathogens dry the wheat plant and shrivel grain. In the warm areas of South Asia, that appearance can lead farmers to blame drought rather than an infection. By “knowing the enemy,” as CIMMYT partner Ram Sharma puts it, it is easier to win the fight against the disease.

CIMMYT pathologist Etienne Duveiller and Sharma, who have both done work on the pathogens, have found an effective method to select for resistance: finding wheat with a heavy grain weight, early maturity, and resistance to both pathogens. Wheat that carries these three traits together makes for wheat with higher resistance. Through regional collaborative trials in South Asia, they have bred and identified wheat lines that look promising. While better than anything previously seen in the area, these wheats can still suffer up to 35% yield losses—and have a huge impact on resource poor farmers who grow their wheat for food, as most do in Nepal.

When the temperature soars to 26-28°C, however, no wheat can resist the disease. This is why it is so important to find wheat that matures early to avoid the abrupt rise in temperature accompanied by hot winds in late March and April. This becomes difficult as most farmers in the region are delayed planting wheat as they wait for their rice harvest to finish and the paddies to dry up.

In addition to genetic resistance, solutions can come in the form of good management. Surface seeding, when seed is broadcast on the mud directly after the rice harvest, allows earlier planting and gives the wheat crop a jump start on the heat. Crop rotation and soil nutrients are important because healthy soils help the crop resist the disease. Also, Duveiller and Sharma have found that wheat is better able to withstand the disease with proper soil moisture.

The CIMMYT-Nepal team expects that these new sources of resistance, coupled with good management practices, will limit the destructiveness of this disease. They know it can be done—foliar blight has already been substantially reduced in areas of South Asia such as Bangladesh through better wheat varieties. The challenge is to sustain progressive control of this threat across the warm wheat growing areas of South Asia.
