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.

One size doesn’t fit all: training on farm household typology

Written by on February 1, 2013. Posted in News.

Since adopting a one-size-fits-all approach in technology generation and dissemination is unlikely to bring positive results, it is necessary to understand what intervention works for whom, where, and how in order for a program to be successful. Developing farm household typologies to target technology with respect to farmers’ endowments and environmental setting is one of the key components of the SIMLESA (Sustainable Intensification of Maize and Legume Cropping Systems in Southern and Eastern Africa) initiative. To identify farm household typologies from baseline surveys carried out in Ethiopia, Kenya, Tanzania, Malawi, and Mozambique, the initiative organized a two-week workshop between November and December 2012 at the University of Queensland, Brisbane, Australia. The event was attended by economists from the five SIMLESA countries and organized by Daniel Rodriguez, leader of Queensland Australia component of the SIMLESA project.

The first week consisted of lectures by experts in household typologies and household modeling in developing countries, econometric modeling of adoption and impact (facilitated by Menale Kassie of CIMMYT and John Asfau of the University of Queensland), household survey data mining, and the use of survey data to parameterize household models. The participants then prepared and delivered brief presentations covering the objectives, research questions, and hypotheses of the key publications distributed among them; methods and main results; and implications of the publications to their own work.

Reflecting their respective survey datasets, the workshop participants then developed a methodology to identify farm household typologies and, subsequently, a new tool using the free R statistical software. The tool was distributed to each of the participants. The utilized approach not only automates the process, but also ensures that the same methodology is applied to each country’s survey dataset, thereby enabling an easier comparison of the results. The workshop was concluded by a short presentation from each participant outlining their findings.
The feedback on the workshop was very positive: many participants intend to instruct their colleagues in their home countries on the techniques they learned to use during the workshop. The Australian SIMLESA team will continue to provide support on the use of R, as well as access to the script to identify household typologies.

Value chain analysis training: putting farmers first

Written by on January 31, 2013. Posted in News.

Value-chain-training Understanding the value chain of maize and legume crops and the ability to define various actors as well as their contributions and constraints along the value chain is crucial in identifying feasible interventions. Since these activities fall within the scope of the SIMLESA (Sustainable Intensification of Maize and Legume Cropping Systems in Southern and Eastern Africa) initiative, national partners and CIMMYT staff took part in a training and writing workshop on value chain analysis held in Addis Ababa, Ethiopia, from 09 to 16 January 2013. The workshop was attended by 14 participants (8 national partners from Ethiopia, Kenya, Tanzania, and Mozambique, and 6 CIMMYT employees), and facilitated by Mot Jaleta (CIMMYT). Its objectives included capacity building and finalizing of pending reports related to Objective 1 of the program (to develop and target opportunities for impact through baseline studies and analysis of input and output value chains with particular reference to maize and legume seed systems and local markets), and among the topics covered were basic concepts of value chain analysis, quantitative methods in value chain analysis, and the identification of opportunities, constraints, and interventions at various stages along the value chain.

In his opening remarks, SIMLESA program leader Mulugetta Mekuria stressed the importance of the socioeconomic component of SIMLESA for technology development and dissemination through interaction with local communities and other stakeholders. “The Objective 1 team should be part and parcel of the technology development process, constantly monitoring and evaluating, and not only waiting till the project ends to do an ex-post study,” stated Mekuria. He also emphasized the importance of understanding the opportunities and constraints underlying the SIMLESA maize and legume input and output markets and highlighted the need for SIMLESA to continue placing the interests of smallholder farmers at the center of the program.

The workshop was concluded by presentations on the progress made on the value chain analysis reports by individual countries. Menale Kassie, SIMLESA socioeconomic component coordinator, then thanked all participants for their attendance and contributions. The participants considered the training a successful platform for learning and sharing experiences, and partners requested more similar technical trainings in the future.

Gender integration and data analysis: a better way to move forward

Written by on January 30, 2013. Posted in News.

Gender mainstreaming in agricultural development is on the agenda of national governments and the international development community (for more information on CIMMYT and gender mainstreaming see “Integrating gender into WHEAT and MAIZE CRPs: A leap forward”). Building upon the 2012 World Development Report: Gender Equality and Development warning that the failure to recognize the roles, differences, and inequities between men and women could pose a serious threat to the effectiveness of agricultural development strategies, the Australian International Food Security Center (AIFSC) approved the Adoption Pathways project in Eastern and Southern Africa. The project aims to collect gender disaggregated data to achieve better understanding of technology adoption, agricultural productivity, and food security in the regions.

To contribute to the objective, the International Food Policy Research Institute (IFPRI) facilitated a training on gender integration and analytical tools in agricultural research and gender disaggregated survey instruments design. The training took place during 08-12 January 2013 in Addis Ababa, Ethiopia, and was attended by over 20 participants from 5 countries (Ethiopia, Kenya, Malawi, Mozambique, and Tanzania) involved in the Adoption Pathways project and the SIMLESA (Sustainable Intensification of Maize and Legume Cropping Systems in Southern and Eastern Africa) initiative. The training materials were based on case studies from IFPRI projects such as the Gender, Agriculture, and Assets Project (GAAP), and the training itself focused on the concepts of gender; gender in agricultural research; gender livelihood conceptual framework; qualitative methods; the relationship between gender, agriculture, and assets; Women’s Empowerment in Agriculture Index (WEAI); and the need for gender disaggregated surveys. The training also provided concrete advice and feedback on how to analyze gender disaggregated data and covered the needs and opportunities for dissemination and outreach, including ways to share results and plans to synthesize lessons learned. Finally, it enabled participants to identify plans for next steps, including updating and refining the SIMLESA survey instrument with gender component.

Maize lethal necrosis (MLN) disease in Kenya and Tanzania: Facts and actions

Written by on January 29, 2013. Posted in News.

A serious new disease of maize appeared in the farmers’ fields in eastern Africa in 2011. Called maize lethal necrosis (MLN; or corn lethal necrosis, CLN), it can devastate maize crops. The disease is difficult to control for two reasons:

It is caused by a combination of two viruses that are difficult to differentiate individually based on visual symptoms.
The insects that transmit the disease-causing viruses may be carried by wind over long distances.

National and global research and extension organizations, laboratories, and seed companies are working together to control the spread of the disease and to develop and deploy disease-resistant maize varieties for the farmers as soon as possible.

CIMMYT mourns the passing of Twumasi-Afriyie, creator of the quality protein maize Obatanpa

Written by on January 14, 2013. Posted in Features.

Dr-Twumasi On 03 January 2013, 63-year-old Ghanaian-born maize breeder Strafford Twumasi-Afriyie succumbed to cancer, leaving a substantive legacy that includes the creation of the world’s most widely-sown quality protein maize (QPM) variety, Obatanpa. His demise represents a huge loss to family, friends, hundreds of colleagues and collaborators, and many thousands of farmers. A highly-committed and knowledgeable scientist, Twumasi is remembered by all for his kind, gentle demeanor and modesty, as well as for building strong partnerships.

Twumasi worked at the Crops Research Institute (CRI), Ghana, through much of his career. Following the completion of his MSc at the University of Guelph, Canada, in 1981, he returned to Ghana to serve with former CIMMYT maize physiologist Greg Edmeades as Joint Coordinator of the Ghana Grains Development Project funded by the Canadian International Development Agency (CIDA). It was during this period and under the aegis of the GGDP that he used CIMMYT germplasm during the early 1990s to develop Obatanpa, which by 2005 was sown on more than half of Ghana’s maize area. With support from Sasakawa-Global 2000, the International Institute of Tropical Agriculture (IITA), and CIDA, Obatanpa has been released in numerous countries of Africa, including Uganda where as “Nalongo” it is among the most popular maize varieties.

Twumasi joined CIMMYT in 1997 to develop maize varieties for African highland areas in a project supported initially by the Federal Ministry for Economic Cooperation and Development, Germany and later the Ethiopian Institute of Agricultural Research (EIAR), CIMMYT, the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA), and CIDA. Releases from that effort are still gaining popularity in high-altitude zones of Ethiopia.

As a breeder in CIDAfunded research in Ethiopia beginning in 2003, Twumasi worked with EIAR to develop a QPM version of the hybrid BH660, which accounts for some 60% of seed sales in Ethiopia. These and other superior varieties developed are being promoted through the new “Nutritious Maize for Ethiopia” project that Twumasi was leading. “The National Maize Program recognizes the relentless work of Dr. Twumasi for small-scale farmers of Ethiopia in particular and Africa in general,” says Berhanu Tadesse, Ethiopia’s National Maize Research Coordinator.

Edmeades remembers Twumasi as scrupulously honest, slow to judgment but always fair, and one of nature’s true gentlemen. “He was not afraid to take risks as a scientist and promote QPM when many others declared it a lost cause,” says Edmeades. “As my counterpart in Ghana I very much enjoyed working with him and came to appreciate his wry sense of humor and his lovely smile.”

Twumasi’s mentorship and tutelage helped several maize researchers from the region develop as strong breeders in their own right. His academic background included a BSc in agriculture from the University of Ghana (1975) and a PhD in plant breeding from the University of Missouri, USA (1989).

The CIMMYT family extends its sympathies to Twumasi’s beloved wife, Veronica, his daughters Mame and Truelove, and his son Kwaku in this difficult time.

Improving wheat seed system and end-use quality in Ethiopia

“My work in Africa is not finished,” Jeanie Borlaug quoted her father, Dr Norman Borlaug, during her opening statement for wheat seed system field day bringing together farmers, researchers, seed growers, and development enterprises experts to discuss improved seed system and end-use quality issues in Ethiopia. The field day was held at the Kulumsa Research Center (KRC), Ethiopia, on 15 November 2012 and was followed by an end-use quality workshop on 16 November. Both events were organized by KRC and CIMMYT and sponsored by Cornell University’s Durable Rust Resistance in Wheat Project (DRRW).

Calls to adopt SIMLESA approach in project implementation across Tanzania

Written by on December 18, 2012. Posted in News.

“The Ministry, and specifically the Directorate of Research and Development, immensely commends SIMLESA’s participatory approach and would like to recommend it to other research and development partners both at national and international levels. By any means, this approach won’t ignore or omit farmer participation in variety dissemination, as was the case in the past. This participation exactly addresses the value chain approach that has been over emphasized by the Agricultural Sector Development Program that we are implementing in our country,” stated Fidelis Myaka (director of Research and Development, Ministry of Agriculture, Food Security and Cooperatives, Tanzania) in a speech read on his behalf by Ruth B. Madulu, Agricultural Research Institute (ARI)-Mikocheni at the recently concluded Tanzania SIMLESA 2012 Progress Review and 2013 Planning Meeting in Arusha.

Improving postharvest grain storage and loss assessment methods

Written by on December 14, 2012. Posted in News.

In November, twelve researchers and development practitioners implementing phase two of the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP II) travelled from Malawi, Zambia, Zimbabwe, and Kenya, for training on improved postharvest grain storage and loss assessment methods in Nairobi, Kenya.

The course was facilitated by Prof. Rick Hodges, University of Greenwich, UK, and CIMMYT Socioeconomist Hugo De Groote, Policy Economist Jones Govereh, and Project Leader Tadele Tefera. Practical and theory sessions covered topics such as hermetic storage, postharvest technologies, estimating storage losses, assessing ear and grain damage, economic data requirements and collection, and economic analysis of on-station and on-farm storage trials.

Participants were also introduced to the Africa Postharvest Loss Information Service (APHLIS); a system with an innovative framework for analyzing and computing quantitative postharvest losses under different farming and environmental conditions in eastern and southern Africa. It was discussed how using the APHLIS downloadable calculator can support loss reduction projects. According to Hodges, the advantages of this system are that its measure of percentage weight loss of grain is based on an actual reduction in the dry weight of grain; it does not account for changes in quality unless the grain is no longer fit for human consumption; and losses are cumulatively calculated from production and including each step in the postharvest chain.

Despite the importance of economically analyzing crop and storage pest losses, Govereh lamented that such analyses are not well established in the research community. “Economic analysis is rarely available, especially for on-farm losses. In most cases, crop losses are commonly overestimated with benefits often overstated and costs underestimated.”

Govereh outlined the economic analysis of crop and storage pests: estimating the extent of the problem (the area infested); estimating the intensity of the problem (infestation levels, damage, and crop loss); testing efficacy of control methods on-station and on-farm; basic economic analysis of new methods; farmer evaluation of new control methods; modeling and econometric analysis; and impact assessment. According to Hodges, estimating postharvest losses helps in influencing policy makers, improving the efficiency of value chains, and identifying opportunities for increasing food security.

Reiterating the economic benefits of storage, Govereh stated: “Most maize is produced by small-scale farmers in one major season and is meant for home consumption. However, consumption is continuous therefore storage is needed to buffer stocks and protect against price fluctuations.”

Abdu Rahman Beshir, a CIMMYT graduate research fellow from Ethiopia, received an award for the best project in the PhD category at a recent Postgraduate Students’ Symposium on Botany and Plant Biotechnology at the University of Johannesburg (UJ) for his paper titled ‘Quality Protein Maize: towards achieving the Millennium Development Goals through better nutrition and stable yields.’ His presentation highlighted the severity of malnutrition in parts of sub-Saharan Africa and the ways quality protein maize (QPM) seeks to address the issue.

Beshir conducted his field research between July 2009 and December 2011 at CIMMYT Kenya, Zimbabwe, and Ethiopia in collaboration with national programs and with support from the Drought Tolerant Maize in Africa (DTMA) Initiative and the Quality Protein Maize Development project. Beshir focuses on the evaluation of yield and secondary traits of early maturing QPM cultivars (both hybrids and open pollinated varieties) under different mega environments of sub-Saharan Africa (his research was featured in Informa 1689). Beshir –is studying at the University of the Free State (UFS) under the supervision of Maryke Labuschagne and Angie Van Biljon (UFS), and Dan Makumbi (CIMMYT) and Peter Setimela (CIMMYT). “I would like to acknowledge the invaluable support from CIMMYT. This award is an indication of the relevance of research conducted at CIMMYT globally,” said Beshir. “There are many people who are looking for such opportunities, who can make a difference and contribute more to science; hence CIMMYT’s efforts are highly commendable,” added Beshir, thanking all who contributed to his studies and career growth.

The UJ symposium is an annual platform for postgraduate students from different universities to present their research findings. These findings are judged by a panel of professors based on the significance of the project, the quality of the content, and delivery.

SIMLESA-Kenya: achievements and future goals

Written by on November 29, 2012. Posted in News.

The Kenya Annual Review and Planning Meeting (ARPM) was held during 5-6 November 2012 at the Kenya Agricultural Research Institute (KARI). The meeting was attended by 33 participants from the Queensland Alliance for Agriculture and Food Innovation (QAAFI), KARI, Ministry of Agriculture, Agriculture Research Council (ARC-SA), International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA), Royal Tropical Institute, Resource Projects Kenya (local NGO), and FRESHCO Seeds (local private seed company). Present were also Stephen Njoka (KARI-Embu) and Francis Muyekho (KARI-Kakamega), who chaired some of the sessions.

Joseph Mureithi, KARI deputy director and SIMLESA program steering committee member for Kenya, welcomed all participants and informed them on the adoption of a new value chain innovation platform, bringing major stakeholders on board to address farmers’ constraints and promote commercialization of agriculture. Ephraim Mukisira then officially opened the meeting by summarizing the outcomes of the KARI Biannual Conference. He discussed the current needs of Kenyan farmers and stressed that “there is need to commercialize the farming business in Kenya in order to empower local farmers.” Besides commercialization, more effort needs to be invested in the SIMLESA initiative. Maize, as the foundation staple in the Kenyan diet, should be promoted together with legumes supplying proteins to the farmers’ families. While the population is rapidly increasing, farm sizes are declining; hence there is a pressing need to increase productivity levels while using the same land area. To realize the program’s impact within the current time constraints, the program aims to assist 50,000 farmers in both Eastern and Western Kenya.

Later on, Mekuria Mulugetta, SIMLESA program leader, provided a detailed background of SIMLESA objectives. He emphasized SIMLESA’s focus on building KARI’s organizational capacity, reminded the participants of the recently published baseline survey report for Kenya, and thanked AusAID for their continuing financial support of the SIMLESA-Ethiopia Expansion program for the next two years. As part of the meeting, the participants travelled to Tanzania, Kenya, and Ethiopia to observe field experiments conducted by SIMLESA, ICRISAT, and national partners.

CIMMYT strengthens partnership with Zimbabwe

Written by on November 15, 2012. Posted in News.

Thomas Lumpkin, CIMMYT director general, and Honorable Joseph Made, Minister of Agriculture and Mechanization of Zimbabwe, signed a new memorandum of understanding on 29 October 2012 to strengthen the relationship between CIMMYT and the government of Zimbabwe.

During the ceremony, Made expressed gratitude to CIMMYT for its continued support of Zimbabwe during the past 10 years of economic hardships. “For so long CIMMYT has been a visitor, but from today it will remain a permanent resident in Zimbabwe and our region — Southern Africa. The Government of Zimbabwe appreciates CIMMYT’s confidence in Zimbabwe to retain its Southern Africa Regional Office and its scientists during the difficult periods we underwent,” said Made. Lumpkin then thanked the Government of Zimbabwe for providing a favorable working environment and support for CIMMYT’s activities. Lumpkin confirmed that CIMMYT would continue to bring cutting-edge science to Zimbabwe and the region as a whole to ensure sustainable maize production. Special focus will be on cooperation in breeding drought and heat tolerant maize varieties, crucial in the face of climate change particularly in sub- Saharan Africa.

The ceremony was attended by a team of senior government officials from the ministry of Agriculture and Mechanization, CIMMYT staff, and Lindiwe Sibanda, CIMMYT Board of Trustees member. During the event, Lumpkin presented the 2012 Award for the Best Maize Breeding Team to Made and the Zimbabwean breeding team for the Drought Tolerant Maize for Africa (DTMA) project. The Zimbabwe team has won this award for the third consecutive year. The DTMA team also received a new pickup truck from Made to facilitate the field breeding work around Zimbabwe.

Sharing experiences with effective grain storage in Africa

Written by on November 14, 2012. Posted in News.

A delegation from Kenya, Malawi, Zimbabwe, and Zambia — the target countries of the Effective Grain Storage for Sustainable Livelihoods of African Farmers (EGSP) Phase-II Project— visited Malawi during 22-23 October and Kenya during 25-26 October 2012 to share experiences with project implementation and to learn about the project’s impact on the livelihoods of smallholder farmers. The delegation comprised of officials from ministries of agriculture and national agricultural research systems from the four EGSP countries, and implementing partners (Kenya Agricultural Research Institute and the Catholic Dioceses of Embu and Homa Bay in Kenya, World Vision in Malawi, Zambia Agricultural Research Institute, and University of Zimbabwe and the Department of Agricultural Mechanization in Zimbabwe).

The tour kicked off in Malawi with visits to Mchinji and Dowa districts. The delegates held discussions with the implementing partners and local artisans trained on metal silo fabrication, school representatives, farmer groups, and farmers who had benefitted from the first phase of the project. Everyone present praised the metal silo for its great results in protecting the grains against the larger grain borers and weevils. “This allows farmers to store maize more effectively and sell it when prices are as high as 47 kwacha [US$ 0.16] per kilogram and not when prices are at 18 kwacha [US$ 0.06] per kilogram,” says Andrew Kasalika, chairman of the Tayamba Group in Mlonyeni Extension Planning Area. “With metal silos, women do not have to climb into granaries, which is quite cumbersome,” added Christine Victory, Tayamba Group’s secretary, noting that the technology is also environmentally friendly, “Men do not have to cut trees to construct the granaries.”

In Kenya, the delegation visited Kamuthatha Boarding Primary School in Embu County, which has acquired six 2,700-kilogram metal silos. Nethy Kathungu, the deputy principal, shared the enormous benefits of metal silos: increased quality of grain and thus increased quality of food for the pupils; reduced postharvest losses (previously amounting to 60% of stored grain); price hikes no longer affecting the school during times of scarcity, as they can now store enough to feed all 450 pupils; no need for pesticides; and less storage space required to store the same amount of grain. As a result, the school saves about Ksh 300,000 (US$ 3,600) per year.

The delegates also visited Gikinyukia Agro-Enterprise Self-Help Group in Mbeere South District, Embu County. The Group participates in collective maize, sorghum, and green grams marketing, and owns three 1,800-kilogram metal silos. According to Gibson Wachira Muchiri, the Group chairman, the plan is to assist every member in acquiring a metal silo through the Group’s fund.

The delegates found the visit very educative and informative, especially officials from Zimbabwe and Zambia who will be implementing the project for the first time. The visit allowed them to witness the implementation of EGSP in Kenya and Malawi as well as the role of different partners in the process. The visits also helped the delegates to identify issues that need to be addressed for the second phase to be successful. These include cost-sharing for sustainability of the project, creating a sense of ownership, and producing a sufficient amount of maize for the metal silos to be fully utilized.

Speaking to the delegates, B.M. Prasanna, CIMMYT’s Global Maize Program director, reiterated the importance of the project in enhancing nutrition and food security of smallholder farmers and consumers. He called on the delegates to be the champions of the project and asked them to take it to the next level: “We can only be a catalyst, but we would like you to be the drivers of this movement. You should stimulate demand for the technology. CIMMYT derives its strength from people like you.” Noting that awareness was critical to the success of the project, Prasanna also encouraged the officials to raise awareness among the target beneficiaries, women, women self-help groups, schools, and women-dominated organizations in particular.

Ugandan farmers also coating seed for Striga control

Written by on November 7, 2012. Posted in News.

A Striga infested maize field in Tororo, Uganda.

In Tororo, Uganda, farmers have been losing most of their maize crop to witchweed. However, they now feel that there is hope as research by CIMMYT and its partners is pro viding a solution. During a recent field day in Tororo, farmers Selina and Charles Emoit hosted their peers at an on-farm demonstration of 15 improved maize varieties. Farmers had the opportunity to observe the trial and select the best performing varieties.

Having planted the maize coated with the chemical imazapyr, Selina said she had seen wonderful results on her farm. Previously, the couple would get almost nothing from the farm as a result of Striga infestation. “What used to be seen from my farm is not what is seen today,” said Selina expressing her joy at being able to save her crop. To ensure that the experiment was successful, Selina explained that they had a different person planting each plot to avoid mix-ups; after germination, some variations were observed on the crops in the field. “Despite all the variations, each one of them has a cob which is better than what I used to get,” said Selina urging fellow farmers to collaborate with researchers to ensure good yields. Selina thanked all the Striga project collaborators who had collectively made it possible to fight the weed on her farm.

Farmers-selecting-varieties The field day was attended by James Ogwang, director of National Crops Resources Research Institute (NaCRRI) at Namulonge; Godfrey Asea, maize breeder and head of the Cereals Program; Pearl and NASECO seed companies representatives; Sammy Waruingi from BASF; and CIMMYT maize breeder Dan Makumbi and research assistant Edna Mageto. Ogwang urged the farmers to plant only certified seed and move beyond border issues to work together in Striga management. Asea thanked the government and farmers for their support in the fight against Striga. He said the farmers had become good project ambassadors.

“Striga is a big challenge to maize production,” said Eva Musenero, District Production Officer, thanking the partners for the efforts towards eliminating the pest. She also urged farmers to embrace new weed management technologies. The farmers who participated in the field day were keen to know how they could access the best performing varieties.

New maize brings hope to farmers in Striga-infested regions in Tanzania and Uganda

Written by on November 6, 2012. Posted in News.

For many years, farmers in Tanzania have desperately tried to control the parasitic flowering plant Striga spp.—popularly known as witchweed—that can make maize farming nearly impossible in regions of heavy infestation. In Tanzania Striga infests an estimated 0.6 million hectares over 10 regions, causing yearly losses to farmers of some 1.7 million tons of grain worth US$ 350 million. For lack of cost-effective control measures for this pest, some farmers have stopped growing maize.

However, there is now hope, thanks to a new maize variety, that is effective in controlling Striga. The variety, TAN222, has the added advantage of being high yielding 3.7 tons per hectare, according to Isaka Mashauri, director of Tanseed International, the company that is commercializing the variety in Tanzania.

Many years of joint research by CIMMYT, BASF (a multinational producer and supplier of agrochemicals), and the Weizmann Institute of Science in Israel have resulted in a solution and source of hope for farmers. It involves coating seed of a herbicide-tolerant maize variety with the systemic herbicide imazapyr. When the seed is sown and sprouts, any Striga plants that attack it are killed. As part of this research, the partners developed herbicide tolerant maize lines based on a natural mutation in maize.

The African Agricultural Technology Foundation (AATF) is promoting this technology among farmers and extension agencies in areas of sub-Saharan Africa where Striga is prevalent. In Tanzania, the seed company Tanseed International has used the herbicide tolerant lines from this effort to develop and market the maize variety TAN222.

Anatia Mike, a farmer in Muheza District, Tanzania, tried using herbicide-coated seed of TAN222 and managed to harvest 1.2 tons of grain per hectare from her Striga infested farm, where previously she was getting yields of only 0.5 tons. At a recent field day organized by the research partners on Mike’s homestead to demonstrate the efficacy of this technology, Karimu Mtambo, the Director of Tanzania’s Ministry of Agriculture, Food Security, and Cooperatives, lauded the practice as the best and most effective in controlling Striga and improving maize yields, and called on farmers to adopt it together with other good agricultural practices.

Also present were Mashauri; Denis Tumwesigye Kyetere and Gospel Omanya, Executive Director and Seed Systems Manager, respectively, AATF; BASF representative Sammy Waruingi; Ibrahim Matovu, Muheza District Commissioner; and from CIMMYT agronomist Fred Kanampiu and breeder Dan Makumbi.

Kyetere promised full support from AATF in scaling out the technology, and Kanampiu called on the government to put in place mechanisms like herbicide registration for commercial use that would facilitate speedy adoption of the technology. He also urged seed companies to work with the Ministry of Agriculture to educate farmers on its use. Matovu promised to have Striga control included in the district agenda, particularly in budgeting.

Recent conference gets wheat back on Africa’s map

Written by on November 5, 2012. Posted in News.

DSCN0042 Wheat is increasingly in demand in sub-Saharan Africa as a result of income growth and the demand for convenience foods as more women enter the workplace, but sub-Saharan countries and Africa as a whole produce only about 30% and 40%, respectively, of their domestic requirements, causing a heavy dependence on imports and making the region highly vulnerable to global market and supply shocks.

This was one conclusion reached by some 250 researchers, policymakers, farmer, and seed company representatives who attended the conference “Wheat for food security in Africa: Science and policy dialogue about the future of wheat in Africa,” held in Addis Ababa during 08-12 October 2012. Organized by Ethiopian Institute of Agricultural Research (EIAR), CIMMYT, ICARDA, IFPRI, the African Union, and WHEAT-the CGIAR research program, the event was intended to raise awareness about the potential to grow wheat and reduce the region’s imports of the crop, as well as to discuss policy, institutional, and infrastructure constraints. “In 2012, African countries will spend about US$12 billion to import some 40 million tons of wheat,” said Hans Braun, director of CIMMYT’s global wheat program. “If Africa does not push for wheat self-sufficiency, it could face more hunger, instability and even political violence, as bread riots in North Africa showed in recent years.”

Participants hailed from 23 African nations, as well as from Asia, Europe, and the Americas, and included 4 ministers of agriculture (Burundi, Ethiopia, Sudan, and Zimbabwe) and the directors of national agricultural research programs of 16 countries in Africa. Deemed a great success by participants and organizers, the event and the issues discussed were reported widely in regional and global media, including major outlets such as Nature, New Scientist, Le Monde, BBC Radio, and Deutsche Welle, as well as key wire services like Reuters-Thomson, Associated Press, and Bloomberg. An equally important outcome was the “Addis Declaration” formulated by conference participants and intended to get wheat onto Africa’s policy map as a strategic product for food security, according to Bekele Shiferaw, director of CIMMYT’s socioeconomics program and a co-author of a major report1 on wheat farming in Africa. “Unlocking the potential of wheat will require changes in attitudes, policy and donor support for adapting farming systems, empowering African farmers, and developing value chains for seeds, input supply, and output markets,” Shiferaw said.

The busy four-day agenda included visits to Ethiopia’s premier agricultural research stations at Kulumsa and Debre Zeit. The conference program committee would like to thank all who contributed, but special recognition goes to logistics team of Petr Kosina, Bekele Abeyo, and Dave Hodson. Presentations, publications, media reports, and posters are available on the conference web page.
