Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

Promising CIMMYT maize inbreds and pre-commercial hybrids identified against maize lethal necrosis (MLN)

Written by on June 14, 2013. Posted in News.

The maize lethal necrosis (MLN) disease first appeared in Kenya’s Rift Valley in 2011 and quickly spread to other parts of Kenya, as well as to Uganda and Tanzania. Caused by a synergistic interplay of maize chlorotic mottle virus (MCMV) and any of the cereal viruses in the family, Potyviridae, such as Sugarcane mosaic virus (SCMV), Maize dwarf mosaic virus (MDMV), or Wheat streak mosaic virus (WSMV), MLN can cause total crop loss if not controlled effectively.

A regional workshop on MLN and the control strategies was organized by CIMMYT and KARI during February 12-14, 2013 in Nairobi, which was attended by some 70 scientists, seed company breeders and managers, and representatives of ministries of agriculture and regulatory authorities in Kenya, Uganda, Tanzania, and the USA. The Workshop led to identification of important action points steps for effectively controlling the disease.

CIMMYT scientists have been working closely with virology experts from USDA-ARS and Kenya Agricultural Research Institute (KARI) to develop suitable protocols for testing the responses of maize germplasm against MLN, and to identify promising inbred lines and hybrids with resistance to MLN. During the 2012-2013 crop season, the CIMMYT-KARI team undertook extensive screening of inbred lines, pre-commercial and commercial hybrids in Naivasha and Narok in Kenya, under high natural disease pressure and artificial inoculation, respectively.

A trial featuring 119 commercial maize varieties (released in Kenya) under artificial inoculation during 2012-2013 revealed that as many as 117 varieties were susceptible to MLN. Another set of trials including 335 elite inbred lines, 366 pre-commercial hybrids and 7 commercial hybrids (as checks) under MLN artificial inoculation in Narok, and another set of trials comprising 350 elite inbred lines and 135 pre-commercial hybrids under natural disease pressure in Naivasha, led to identification of some promising CIMMYT inbred lines as well as pre-commercial hybrids showing resistance or moderate resistance. These results offer considerable hope to combat, through breeding efforts, the deadly MLN disease that has severely affected maize harvests and discouraged farmers from growing maize in eastern Africa.

Notes on trial results

The details of the promising CIMMYT elite inbred lines and pre-commercial hybrids against MLN are presented in Table 1 and Table 2, respectively. The results presented in Table 1 are based on evaluation of CIMMYT inbred lines in four independent trials, two under artificial inoculation (Narok) and two under natural disease pressure (Naivasha) during 2012-2013. In each trial, entries were replicated (minimum two), and MLN severity scores (on a 1-5 scale basis) were recorded three or more times during the crop cycle, from the vegetative to the reproductive stage. The highest average MLN severity score (max. MLN score), recorded at any stage during the trial, is presented as representative of a given entry.

The data must be critically assessed and cautiously used by stakeholders and partners. More weight should be given to data from artificially inoculated trials, since trials under natural disease pressure are more liable to ‘disease escapes’ and identification of false positives. Caution must be exercised when using specific lines identified as potentially resistant (R) or moderately resistant (MR), especially when classification is based on data from only one trial (even under artificial inoculation). Please note that in such cases, the responses of the lines need to be validated by CIMMYT through further trials.

CIMMYT is working closely with both public and private sector partners to significantly expand the MLN evaluation network capacity in eastern Africa, and will continue the intensive efforts to identify/develop and deliver new sources of resistance to MLN.

Extension personnel urged to lead by example in promoting metal silos

Written by on June 13, 2013. Posted in News.

Metal-Silos5 Agricultural extension service staff members in Zambia have been challenged to be the first adopters of metal silos to help promote the technology for effective grain storage. “I implore you, extension workers, to be the first adopters and users of the metal silo technology. As citizens that live side by side with farmers, go and be the first to practice what you will be preaching. You must lead by example,” stated Bert Mushala, the Permanent Secretary, Provincial Administration, Office of the President, Eastern Province, in a speech read on his behalf by his assistant Beenzu Chichuka at the official opening of the Improved Postharvest Management Training Workshop for Extension and Media Personnel held during 27- 28 May 2013 in Chipata, Zambia. “Farmers learn by seeing. Therefore, before they start using the metal silos, they want to see the chief executives, the business executives, extension workers, journalists, and other opinion leaders in the forefront, zealously storing maize in the metal silos,” he added.

The purpose of the training was to build technical capacity on hermetic grain storage technologies, such as metal silos and super grain bags, among extension and media staff in the project implementation districts of Chipata and Katete. The workshop intended to create awareness on the importance of grain post-harvest management, help gain insights into different factors affecting post-harvest management, and provide a better understanding of traditional and improved post-harvest technologies and their use in grain loss reduction, summarized Tadele Tefera, CIMMYT entomologist and the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP II) coordinator. Ivor Mukuka, EGSP national coordinator for Zambia and ZARI chief agricultural research officer, noted that this was part of the process of sharing information on EGSP as a means of promoting effective grain storage and thus helping smallholder farmers safely keep their grains for longer and sell when the time and price are right.

Reiterating the importance of the technology, Mushala noted that self-sufficiency in food grains in the country does not depend only on increased production and productivity, but also on minimizing losses both in the field and during storage. Over the years, supporting organizations and other partners, including the Ministry of Agriculture and Livestock, have poured colossal amounts of resources into the production component of the sector. “The resultant improved yield gains, especially in maize, have largely been wasted through post-harvest losses,” regretted Mushala, adding that “this project is therefore unique and outstanding to us in Zambia as it focuses on the comparatively neglected storage aspects. It is the first one of its kind and could not have come at a better time.”

Mushala then reminded the journalists that they had an enormous task of educating the masses on the new form of storage as many citizens, even in urban areas, are engaged in agriculture. “Go and empower the masses with this information so that together, we can reduce on-farm storage losses to zero,” Mushala urged the participants. Eastern Province Agriculture coordinator Obvious Kabinda called for commitment: “You must have confidence and belief in the technology if you are to successfully promote it to others.”

The messages did not get lost on the participants. “I have gained good knowledge of the technology and, like other trainees, will be using it to ensure that farmers are aware of its existence, have access to it, and are able to adopt the metal silos,” said Michelo Lubinda, a producer with the Zambia News and Information Services (ZANIS), confirming the usefulness of the workshop.

Tefera thanked the Zambia Agricultural Research Institute (ZARI) and the Ministry of Agriculture for their commitment in implementing the project in Zambia, and the Swiss Agency for Development and Cooperation (SDC) for funding the project.

The training was organized by CIMMYT, ZARI, and the Department of Mechanization, Ministry of Agriculture, and facilitated by Tefera, Mukuka, CIMMYT agricultural economist Hugo De Groote, EGSP policy economist Jones Govereh, and senior mechanization specialist Moffat Khosa and principal agricultural engineer Egbet Munganama from the Department of Mechanization Ministry of Agriculture, Zambia.

Farmers in Kenya’s Embu County try nitrogen use efficient maize varieties

Written by on June 10, 2013. Posted in Features.

High fertilizer prices are among the major constraints facing maize farmers in Eastern and Southern Africa. “We apply just a little fertilizer, just the way you would apply salt to taste,” says a maize farmer in the Embu County, Kenya. “We lack enough fertilizer for our maize crop,” explains another one during a focus group discussion.

Kenya imports all its fertilizer, which results in high input costs borne by smallholder farmers. As agriculture forms the backbone of Kenya’s economy, the government offers farmers fertilizer at subsidized rates. “The subsidized price of Urea is about US$ 30 per 50kg bag, while without the subsidy it goes for up to US$ 50 per 50kg bag,” said the County’s land development officer Samuel Kibiu. “Despite the subsidy, not all farmers can afford the fertilizer,” he added. But even if they can, they still have to face several other challenges, such as transporting the fertilizer to their farms in Kieni, about 40 kilometers from the collection point in Embu town, after going through an elaborate process of obtaining subsidy receipts from the local agriculture office.

In October 2012, a team from CIMMYT’s Improved Maize for African Soils (IMAS) project, together with the Kenya Agricultural Research Institute (KARI) and extension workers from the Ministry of Agriculture, visited a group of farmers in the Kieni Division, Embu County. “Fertilizer is essential in Sub-Saharan Africa,’’ says Biswanath Das, IMAS project leader, “but fertilizer use in the region is amongst the lowest in the world, averaging less than 20kg per hectare.” This falls way below the recommended application rates and below average of what farmers apply in Asia and Latin America. “Most smallholder farmers in Africa are extremely risk averse, as the bulk of smallholder production is under rain-fed systems,” says Das. “As a result, farmers are reluctant to invest in expensive inputs such as fertilizer due to unpredictable rainfall.”

Making fertilizer more accessible in Africa has proved extremely difficult and researchers have thus begun searching for other ways to address the issue. The IMAS project is developing new maize varieties that are more efficient at using the small quantities of nitrogen currently applied in smallholder maize production systems in Southern and Eastern Africa. The goal is to develop maize varieties that yield up to 50% more than the existing varieties through better nitrogen use efficiency. The first set of varieties developed through the IMAS breeding pipeline showed promising results during onstation trials and is being tested by farmers in Kieni. “Despite the poor rains, we got good yields,” said Mercy Wawira commenting on the IMAS hybrid she planted on her farm. “We have seen our yields improve with this new variety,” said John Bosco Mugendi who also participated in the IMAS on-farm trial. “This variety is good,” he added. Members of the community were present to help Wawira and Mugendi harvest the maize from the small trial plot. “We hope we shall get this variety again to plant in the next season,” said Obed Nyaga Njamura, agribusiness development officer in Embu’s Kieni Division.

Farmer John Bosco Mugambi also participated in the IMAS on-farm trial in the Embu County.

As yield gains observed under managed low-nitrogen stress trials on station are being replicated under farm conditions in the region, IMAS scientists feel encouraged. Together with partners in the national agricultural research systems in Eastern and Southern Africa (KARI and the Agricultural Research Council of South Africa, ARC) and Pioneer Hi-Bred in the USA, IMAS is developing nitrogen use efficient varieties to benefit smallholder maize farmers in Africa. “We broker technology through these partnerships. We also build capacity through the comparative advantage in the different institutions,” said KARI’s director Ephraim Mukisira.

A new era for Agricultural Innovation in Pakistan

Written by on June 4, 2013. Posted in News.

On 27-28 May, representatives from CIMMYT, USAID, the Pakistan Agricultural Research Council (PARC), ILRI, IRRI, AVRDC, and UC Davis met with colleagues from several Pakistan universities, agricultural secretaries of the provinces, development sector organizations, private sector representatives, and farmer organizations, to discuss and plan the next stage of the USAID-supported Agricultural Innovation Program for Pakistan (AIP).

In his opening address, Randy Chester, USAID’s Deputy Office Chief for Agriculture, stated that “AIP represents a unique and unprecedented collaboration, in that it will bring together the expertise and resources of all of these organizations, including USAID, to increase the income of farmers across Pakistan.” By using the Global Conference on Agricultural Research for Development (GCARD) approach of agricultural research for development (AR4D), AIP “will foster a demand-driven, results-oriented, science research community, and enhance linkages between Pakistan’s agricultural research and innovation communities, the wider global community of agricultural scientists, and the private and civil society sectors,” he concluded.

AIP is a unique program for CIMMYT, aiming to address not only cereals and cereal systems, but also livestock, vegetables, and fruit trees, through a combination of commissioned projects, a competitive grants system, and human resource development. The program will draw on the expertise and resources of the five international partners, but many other Pakistan partners will be brought on as the program develops. PARC Chairman, Iftikhar Ahmad, highlighted the role that Pakistan organizations have to play: “We need a new kind of collaboration,” he said. “It must be a two-way process in that Pakistan must also contribute to international science. Pakistani scientists must play a crucial role in paying back what we get from the outside. Other economies can benefit from Pakistani science as well,” he added.

It would not be the first time that Pakistan has positively impacted worldwide agricultural development. Its national agricultural research system was instrumental in identifying two high-yielding wheat mega-varieties, ‘Mexi-Pak’ and ‘Pak81’, also known as ‘Siete Cerros’ and ‘Seri’, respectively, recalled Hans Braun, Director of CIMMYT’s Global Wheat Program.

During spirited working groups, participants put forward their suggestions for project priorities that will enable AIP to increase the incomes of tens of thousands of farmers, through increased agricultural productivity, in the shortest time frame possible. There will be a strong focus on adapting and up-scaling existing technologies present elsewhere in the region, such as Greenseeker sensors for improved nutrient management.

Closing the meetings, Jonathon Conly, USAID Mission Director, Pakistan, praised the group in their collaboration to revolutionize Pakistan’s agricultural sector. “If we care about driving economic growth, it has to be done by increasing farm productivity, by increasing adoption of technologies, and human capacity,” he said; concluding: “I believe that AIP will lead to the desperately-needed increases in agricultural productivity in this country.” Pakistan35

Collaborative wheat breeding for durable resistance to stripe rust in China

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

Chinese-wheat-grower Breeding of durable resistance to stripe rust —the greatest biotic threat to wheat production in the largest wheat producer and consumer in the world, China— was the major theme of a workshop jointly organized by the CIMMYT-Sichuan office and the Sichuan Academy of Agricultural Sciences (SAAS) at the SAAS Plant Breeding Institute in Chengdu, Sichuan province, China, on 18 May 2013. The workshop aimed to promote the adoption of second-generation parents and slow-rusting breeding strategies in spring wheat-producing areas of China and to facilitate collaborative breeding strategies between SAAS and its sister organizations in neighboring provinces. The workshop consisted of a seminar and a discussion session on germplasm and breeding strategies led by Gary Rosewarne (CIMMYT Global Wheat Program senior scientist) and Bob McIntosh (Emeritus Professor at the University of Sydney), and followed by a field visit to the Southern China Field Station at Xindu.

China has the largest area prone to stripe rust epidemics in the world. Traditionally, the disease has been controlled through genetic strategies focused on incorporating major seedling resistance genes to provide immunity. However, this method places strong pressure on the fungus to evolve and overcome these genes. Since the 1950s, the development of virulent pathotypes to widely used resistance genes has caused numerous serious stripe rust epidemics, with the major ones in 1990 and 2002 resulting in the loss of 2.65 and 1 million tons of grain, respectively. Given China’s importance in the world’s wheat production and consumption, any threat to the country’s wheat production has implications for global food security.

CIMMYT has pioneered breeding of durable resistance to stripe rust through the incorporation of multiple, slow-rusting loci, a breeding strategy well established at SAAS but largely ignored by most other wheat breeders in China who still focus on major seedling resistance. At the beginning of this century, SAAS and CIMMYT established a shuttle breeding system to introduce slowrusting loci into Sichuan germplasm. Five high-yielding but susceptible Sichuan lines were sent to Mexico each year for three years; Ravi Singh, CIMMYT distinguished scientist and head of Bread Wheat Improvement, then made single backcrosses with several CIMMYT donor lines. The resulting lines were advanced in Toluca and Obregón, Mexico, and large populations of early generation materials were sent back to Sichuan for further advancement and final selection. Fixed lines from these first generation crosses have shown good levels of resistance in China, along with yields comparable to those of the check varieties. There is currently a range of second generation parental lines with slow-rusting loci in Chinese backgrounds; it is expected that with these as donors, researchers should be able to raise yield potential further while maintaining resistance.

The workshop resulted in a proposed collaborative strategy which would allow breeders representing different regions of China to receive several lines of second generation Chinese slow-rusting donors and to conduct single backcrosses with some of their elite germplasm that has become susceptible. Chinese scientists involved in the process will be invited to help select early generation materials using the bulk selection methodology. After selection, large early generation populations will be sent back to the regions for further selection and advancement under local conditions. “We anticipate that through this mentoring process, breeders will feel comfortable adopting new breeding strategies that can increase their efficiencies and ensure that durable stripe rust resistant lines are released throughout China,” explained Rosewarne.

Swiss Ambassador visits CIMMYT-Harare

Physiologist Jill Cairns talks about climate change with the Swiss Ambassador. — Physiologist Jill Cairns talks about climate
change with the Swiss Ambassador.

The Ambassador of Switzerland to Angola, Malawi, Zambia, and Zimbabwe, Luciano Lavizzari, accompanied by the Swiss Agency for Development and Cooperation (SDC) Food Security program officer for Zimbabwe Mkhululi Ngwenya, visited the CIMMYT Regional office for Southern Africa in Harare, Zimbabwe, on 23 April 2013. The CIMMYT-Harare staff provided a tour around the facilities and briefed them on CIMMYT’s work on food security geared towards finding solutions to challenges faced by farmers.

In the beginning of the visit, CIMMYT physiologist Jill Cairns discussed the issue of climate change. “As a result of climate change, the seasons are going to be much shorter,” explained Cairns, adding that in a region with the lowest maize yields globally, a lot more effort is required to deploy germplasm and farming systems adapted to respond to constraints in the region. Cairns discussed the work done by CIMMYT scientists in countering stresses such as low nitrogen, drought, and heat stress along the maize breeding pipeline from population development, pedigree breeding, to regional and on-farm trials in over 100 diverse locations. She also covered the phenotyping tools used in the research work and highlighted research gains in maize yields, many of which result from highly drought-tolerant maize lines and improved efficiencies of maize breeding pipeline in Eastern and Southern Africa.

John MacRobert, seed systems specialist, highlighted the importance of harmonizing seed systems in the region. “Some countries, like Zimbabwe, have very well developed seed sectors, while others are largely informal,” MacRobert said, stressing the negative consequences this may have on farmers. He then explained the importance of on-farm trials in incorporating farmer preferences such as grain texture in breeding work, using the example of SDC-funded New Seed Initiative for Maize in Southern Africa (NSIMA), a project whose acronym is fashioned after a popular maize staple dish in Zambia and Malawi known as nsima: “NSIMA targets a subset of smallholder farmers who consume the maize that they grow.” MacRobert also highlighted collaboration with other SDC projects whose seed systems encourage community-based seed companies targeting smallholder farmers.

Next on the agenda was conservation agriculture covered by agronomist Christian Thierfelder. “It is crucial to link improved varieties with the best management practices to ensure the sustainability of the cropping system,” stressed Thierfelder who then went on to demonstrate a range of sowing equipment from a stick to animal traction planters used in conservation agriculture.

Seed systems specialist Peter Setimela explains the importance of regional on-farm trials to the Swiss Ambassador Luciano Lavizzari (middle) and SDC Food Security program officer for Zimbabwe Mkhululi Ngwenya.

Socioeconomist Girma T. Kassie turned attention to the consequences of lack of funding for smallholder farmers. For example, lack of funding programs to help the smallholder farmers acquire equipment limits uptake of improved planting practices. “Research on the impact of improved technologies aimed at improving livelihoods of smallholder farmers can help identify the gaps in technology transfer,” he added. Afterwards, the visitors toured CIMMYT trials where they observed the discussed technologies in the field.

CIMMYT has had a long-standing relationship with Switzerland through SDC, which currently funds several CIMMYT projects geared towards improving food security of smallholder farmers in East and Southern Africa. The projects, focusing on post-harvest losses reduction, conservation agriculture, and improved seed systems, include the Effective Grain Storage Project (EGSP), Seeds and Markets Project (SAMP), Harmonized Seed Security Project (HaSSP), and NSIMA. In addition, the SDC funds the ‘SDC-Junior Professional Officer’ supporting agronomist Stephanie Cheesman at the Global Conservation Agriculture Program team. CIMMYT highly appreciates the continued support from the Swiss government through SDC.

US Ambassador to Pakistan visits National Agricultural Research Center in Islamabad

Written by on May 21, 2013. Posted in News.

Pakistan-(1) — US ambassador hands Wintersteiger keys to the chairman of PARC.

On 8 May 2013, US ambassador Richard Olson reaffirmed the United States government’s long-term support to farming communities in Pakistan during his visit to the National Agricultural Research Center (NARC) in Islamabad. The visit, organized by CIMMYT in collaboration with US embassy in Pakistan and Pakistan Agricultural research Council (PARC)/NARC, was to recognize the success of the Wheat Productivity Enhancement Project (WPEP), a USDA program implemented by CIMMYT in collaboration with national and provincial research partners, and to inaugurate the harvesting ceremony for the Ug99 resistant wheat variety called NARC 2011. “Since the 1950s, the United States has been working to support agriculture in Pakistan,” stated Olson. “Wheat accounts for approximately 60% of the daily caloric intake of the average Pakistani, so our joint efforts to combat this disease are critical.”

Muhammad Imtiaz, CIMMYT country liaison officer and wheat breeder, briefed the ambassador on CIMMYT’s mission to sustainably increase productivity of wheat and maize systems to ensure global food security and reduce poverty. “CIMMYT collaboration on sustainable agricultural research with national and provincial research institutes in Pakistan began when Dr. Manzoor Bajwa and Dr. Norman Borlaug worked together to develop ‘Mexi-Pak,’ the wheat variety that started the Green Revolution in Pakistan and helped to double Pakistan’s wheat production between 1965 and 1970,” Imtiaz commented on the long-lasting importance of the partnership for Pakistani farmers. The work is not over as the need for disease resistant wheat varieties continues: experts estimate that Pakistan’s annual wheat harvest could be reduced by as much as 50% if and when Ug99 arrives. “Agriculture contributes 21% to the GDP of Pakistan and employs 45% of the labor force, making it one of the most significant economic drivers of Pakistan,” Imtiaz explained the importance of the sector. Pakistani farmers grew about 24 million tons of wheat on 8 million hectares last year, accounting for about 2.4% of the GDP.

Abdul Basit Khan, Additional Secretary at the Ministry of National Food Security and Research, and Iftikar Ahmed, PARC Chairman, appreciated CIMMYT’s effective role in wheat improvement through technical support and implementation of international funded projects, and reiterated its importance for enhancement of the research efficiency and capacity of Handing over of Wintersteiger key to Chairman PARC Pakistani national institutes.

Nutritious Maize for Ethiopia and gender

Written by on May 16, 2013. Posted in News.

The Nutritious Maize for Ethiopia (NuME) aims to develop and promote quality protein maize (QPM) in the major maize growing areas of Ethiopia, including the highlands and the dry lands, to improve nutritional status of children. The project has a strong gender component, ensuring women’s full participation in all activities and equal share of benefits, which was discussed during a Gender Analysis and Strategy workshop at the ILRI campus in Addis Ababa, Ethiopia, on 16 April 2013. The purpose of the event was to present gender analysis and gender strategy developed by Kidist Gebreselasie, NuME gender consultant, to implementation partners, receive partners’ input, agree on strategy, and discuss future developments. The workshop was attended by representatives from the Ethiopian Institute of Agricultural Research (EIAR), ministries of health and agriculture, the Ethiopian Health and Nutrition Research Institute (EHNRI), SG2000, FRI, the Ethiopian Seed Enterprise, other seed companies, Hawassa University, Harvard Institute of Public Health, and CIDA (the project’s funder). CIMMYT was represented by Dagne Wegary (interim project coordinator), Dennis Friesen (project advisor/consultant), Vongai Kandiwa (gender specialist), and Hugo De Groote (agricultural economist).

In the opening session of the workshop, Gebreselasie presented her synthesis developed in collaboration with CIMMYT scientists and based on literature review, analysis of a baseline survey (both men and women were interviewed), and an indepth study of two target areas (including focus group discussions and key informant interviews). Gebreselasie found that while men are responsible for plowing and purchase of inputs, including seed, women are responsible for household chores such as cooking and child care. However, both men and women contribute to harvesting and weeding. Planting is either a shared activity, or one done by men. Children are also involved in agricultural activities as they play an important role in herding animals and providing feed and water. Dairy and poultry production management is largely a women’s responsibility; although women receive a substantial part of the income resulting from these activities, their access to resources, as compared to men’s, is largely limited, particularly when it comes to extension services. The agricultural extension system focuses on men and female-headed households; wives are expected to learn from their husbands. Women are also rarely invited to agricultural trainings, especially when they take place outside of their own farm. It is much easier for women to access health extension than agricultural extension workers.

Gebreselasie then outlined a gender strategy to address the above listed constraints and to improve women’s participation in project activities. This involves increasing women’s attendance at QPM demonstrations by inviting them directly and by organizing separate sessions for women during field days, ensuring that the time and place is convenient for them. Gebreselasie suggested involvement of health extension workers in QPM promotion and higher level of women’s involvement in farm radio activities (targeting women). Furthermore, partners should be given incentives to involve women more, and they should also be provided gender training at all levels.

After the presentation, the workshop participants reviewed their organizations’ experiences in gender activities and their responses to the analysis, and discussed ways to incorporate the strategy in their activities.

The NuME gender strategy was later presented and discussed during a meeting of the Project Steering Committee on 23 May at ILRI. CIDA representative Stefna Pacquette emphasized that the strategy needs to involve women in a meaningful way beyond simple participation in project activities. “While focusing on nutrition, NuME can provide a vehicle for strengthening women’s role in the household,” Pacquette noted. “It can also get men to feel more comfortable with women’s presence and participation in traditional male roles.” The next necessary step for NuME is the recruitment of a gender specialist to aid implementation of the strategy.

Generating drought tolerant maize varieties in Latin America

Written by on May 15, 2013. Posted in News.

S03TLWN-ears-Colombia On 26-27 April 2013, the FONTAGRO “Generation and validation
of drought tolerant maize varieties to stabilize and reduce mycotoxin damage resulting from climate change” project held its end-of-project meeting in La Ceiba, Honduras, along with the Central American Cooperative Program for the Improvement of Crops and Animals (PCCMCA) meeting (21-26 April). The event highlighted the advances to date, the project’s products, and recommendations for follow-up to ensure that the products reach farmers.

Since 2009, the project generated 5,000 doubled haploid (DH) lines which are currently being evaluated by CIMMYT. The populations were developed from inbred lines identified for drought tolerance, ear rot resistance, and reduced mycotoxin accumulation. The project also identified a set of inbred lines with high levels of ear rot and mycotoxin resistance. The information has been shared with project partners and other breeders for wide use, and CIMMYT will distribute these lines to interested parties. CIMMYT maize breeder Luis Narro commented on the research on diseases, ear rots in particular. “Ear rot is increasing in incidence and severity in South America. Evaluation of 18 commercial hybrids in Peru revealed ear rot incidences as high as 42% on susceptible hybrids in some locations,” he said. “Ear rot tolerant hybrids identified in this project will play an important role in mitigating the detrimental effects posed by ear rots and mycotoxin contamination. These need to be promoted to reach farmers rapidly.” As far as mycotoxins are concerned, the team also identified promising hybrids from validation trials documenting the natural incidence of mycotoxins in Peru, Colombia, and Mexico. This study showed that fumonisins are the most prevalent mycotoxin in South America (compared to aflatoxin and deoxynivalenol).

“The project has generated many products and validated some that are now being released in several countries,” said the project leader George Mahuku. Among those are four varieties released in Honduras (three white and one yellow); one white variety in Colombia; two varieties (one yellow, one white) and a yellow hybrid in Nicaragua, and three varieties (two yellow and one white) in Panama. Three hybrids outperforming the local commercial checks are under validation in Peru. Furthermore, two varieties showing the stability and rustic nature of CIMMYT-generated varieties were released in Colombia, Honduras, and Nicaragua. All the released cultivars are moderately tolerant to the tar spot complex disease which is becoming more common in Latin America.
CIMMYT maize breeder Felix San Vicente presented on the advances that have been made in breeding for drought tolerance and ear rot resistance. “We need to establish and maintain a regional network to test our products in marginal areas,” he noted. “We hope that we will be able to leverage funding from the CRP [MAIZE] to continue the validation and dissemination of these important and promising products in the region.” During the meeting, scientists presented 29 papers, 5 of which contained results from the FONTAGRO project. The papers of CIMMYT colleagues Román Gordon and Oscar Cruz were awarded for their contributions to the maize section of the project: Gordon received the first prize for his paper “Selection of maize varieties for tolerance to water stress in Panama 2010-2012,” and Cruz received the second prize for his paper on “Participatory validation of white and yellow maize varieties in two regions of Honduras.”

Fontagro-Laceiba-Honduras-019 The project has generally been considered very successful. “We now know which mycotoxins are important in the region and we have the products to potentially minimize the risk,” commented Mahuku. “What we need is to widely test and disseminate the products so that they reach as many farmers as possible. With a little infusion of resources, the dedication demonstrated by this group, and support from policy makers, I have no doubt that we will get there.”

During 23-25 July, FONTAGRO will hold its annual meeting (VIII Taller de Seguimiento Técnico de Proyectos FONTAGRO) in Uruguay. The “Generation and validation of drought tolerant maize varieties to stabilize and reduce mycotoxin damage resulting from climate change” is one of five projects finishing this year; its representatives were invited to present their results and compete for a financial award given to the best project. If the project wins, the financial resources could help with continued and wider validation of products generated by this project.

“I am so excited to be here,” said Dr. Evangelina Villegas as she received her Outstanding Alumni Award from the Department of Grain Science and Industry at the Kansas State University (KSU) at CIMMYT-El Batán on 07 May 2013. “This award is not just for me,” she added, “it is for everyone who worked with me, and everyone I worked with. I have such fond memories of my time both at CIMMYT and Kansas State, and I am very appreciative of the awards I am receiving today.” Awards? Yes, besides the KSU Award honoring Dr. Villegas and her achievements in helping to alleviate hunger and malnutrition, she also received the CIMMYT-Borlaug Award for her contributions to the Green Revolution. “Eva is an incredible woman who helped to achieve incredible progress in the improvement of maize and wheat,” said Thomas Lumpkin, CIMMYT director general, during the ceremony.

Dr. Villegas spent more than 20 years working for CIMMYT as a cereal chemist in charge of the cereal protein quality laboratory. “It was in this laboratory,” noted Lumpkin in his opening speech, “that Dr. Villegas worked with Dr. Surinder K. Vasal to develop quality protein maize, or QPM.” By the year 2000, QPM was grown on more than 1 million hectares worldwide, dramatically reversing the effects of malnutrition and increasing child health. This work earned the two researchers the 2000 World Food Prize. Dr. Villegas was the first female ever awarded this accolade, and she became a role model for women worldwide. But her “contributions to society did not end with science,” Lumpkin reminded the audience. Dr. Villegas was also responsible for overseeing an education fund for the young ‘bird boys’ of CIMMYT, who were hired to protect the experimental crops from being eaten by birds. Her efforts helped many of them pay for schooling.

After Lumpkin’s introductory speech, the microphone went to Dirk Maier, head of the Department of Grain Sciences and Industry at KSU, where Dr. Villegas received her Master’s degree in 1962. “I was reading Noel Vietmeyer’s ‘Our Daily Bread, The Essential Norman Borlaug’ and it was not until I got to about page 176 when I learned about Dr. Villegas,” said Maier. “We feel very sorry that it took us so many years to realize what a distinguished alumna we have in Dr. Villegas. We use her story to inspire our students; it helps them to understand the importance of food production and food security.” Jesús Moncada de la Fuente, director general of Colegio de Postgraduados and long-time friend of Dr. Villegas, then lauded her friendly personality and incredible flexibility in her work: “Usually, people work only on wheat, or only on maize, but Evangelina worked on both. She was a hybrid in that sense.”

“We are honored to call Dr. Evangelina Villegas a member of the CIMMYT family, and are delighted that she has chosen to receive her most recent accolade, from Kansas State University, here at CIMMYT Headquarters,” concluded Lumpkin before taking Dr. Villegas and the guests on a tour around CIMMYT, including the new Biosciences Complex.

CIMMYT promotes China-Australia collaboration on wheat improvement

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

PM-Visit-China-Apr2013 The Chinese Academy of Agricultural Sciences (CAAS)
and Murdoch University, Australia, with financial support from the Chinese Ministry of Science and Technology and the Australian government, officially opened the Australia-China Joint Center for Wheat Improvement in Beijing, China, on 9 April 2013. The center is one of six approved jointly by the two governments. It was opened in the presence of the Prime Minister of Australia Honorable Julia Gillard, CAAS President Jiayang Li, CIMMYT distinguished scientist and liaison officer for China Zhonghu He, and Rudi Appels from Murdoch University. The establishment of the center builds upon more than 10 years of successful wheat quality improvement collaboration between the CAAS-CIMMYT wheat program and Murdoch University.

During 15-17 April, over 50 participants from Murdoch and 8 Chinese institutes attended a workshop for the Australia-China Joint Center for Wheat Improvement held in Beijing. They focused on discovery of new genes, development of elite germplasm, and development of gene specific markers by genomic approach for important traits such as yield, drought resistance, and quality. Ten scholarships, each for 12 months, are available for Chinese postgraduate students to work on thesis research at Murdoch University.

Successful partners’ day at CIMMYT-Harare showcasing research work

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

The value of CIMMYT’s research work is enhanced through partnerships supporting the development and dissemination of new maize production technologies. To encourage this collaboration, the CIMMYT Southern Africa regional office in Harare, Zimbabwe, holds an annual event during which stakeholders from the ministries of agriculture, academic institutions, seed companies, and donor representatives tour field trials and get acquainted with the station’s research outputs.

On 05 April 2013, the Australian ambassador Matthew Neuhaus together with donor representatives from the European Union, AusAID, and the Swiss Agency for Development and Cooperation joined stakeholders from Zimbabwe, Mozambique, Lesotho, Swaziland, South Africa, and the Democratic Republic of the Congo for a successful partners’ day. Over 200 visitors explored CIMMYT fields, observed various products on the maize breeding pipeline such as trials on drought tolerance, nitrogen use efficiency, and demonstrations on conservation agriculture. Visitors also learned about small-scale farm mechanization for conservation agriculture and management of post-harvest losses through the use of metal silos.

During the field tour, it was evident that CIMMYT is incorporating legumes into maize production systems. This not only includes cover crop that contributes to nitrogen fixing but also grain legumes to improve diversity in the farming households’ nutrition. “CIMMYT is keen to see farmers gain more yield per unit area as opposed to having them increase the acreage under maize,” explained Mulugetta Mekuria, regional liaison officer for southern Africa. “When the maize yield is increased on a small portion of the land, the family can then use the rest of the land to grow high value crops such as pigeon peas that are being successfully exported to India from Mozambique and Tanzania,” he added.

Nutrition was a topic of other parts of the partners’ day as well. Farmers in most of the African continent prefer white maize but where diets are predominantly based on maize, especially with weaned infants, nutritional deficiencies may arise. Two exciting options for overcoming such nutritional deficiencies are quality protein maize (QPM) and vitamin A maize (also called orange maize). The QPM varieties have increased amounts of the essential amino acids lysine and tryptophan thereby enhancing the protein quality of maize and contribute to reducing malnutrition that is often seen in children under five years of age who are commonly weaned on maize porridge. “The mothers may not be able to ensure their children’s nutrition needs with the food they currently have,” said seed systems specialist John MacRobert, as he explained the benefits of QPM varieties. The orange maize has improved levels of pro-vitamin A and may help in alleviating vitamin A deficiency. Two varieties have been released in Zambia and two are in pre-release in Zimbabwe. During the tour, seed company representatives were encouraged to identify pre-release materials in which they may be interested.

The tour elicited a lot of interest from the participants who engaged the scientists in discussions, asked questions, and commented on the benefits of new technologies. Kgotso Madisa, an extension officer from Botswana’s Ministry of Agriculture, highlighted the value of nitrogen use efficient maize for farmers who cannot afford to apply the recommended fertilizer doses. “Most of our smallholder farmers are resource poor, these varieties would be of benefit to them,” said Madisa with reference to the hybrids developed under the Improved Maize for African Soils (IMAS) project.

Arsénio Mutatisse from Mozambique’s Higher Polytechnic Institute of Manica confessed that he had been skeptical about conservation agriculture before the event. However, after hearing agronomist Christian Thierfelder explain how to implement conservation agriculture successfully and after observing the trial, Mutatisse said he was convinced about its benefits. “This event was really helpful for us to see how the varieties perform in trials as we work closely with CIMMYT to ensure they get to the farmers,” said Helene Dinova Nsolani, leader of a group of community seed producers in the Democratic Republic of the Congo.

The partners’ day was made possible through the help of CIMMYT’s national staff and intern students working at the station. Thanks to training provided by the regional office, the students have all the necessary knowledge and were thus instrumental in explaining the technologies on display. “We do capacity building to ensure that whenever we move on, we have people to continue with the breeding work,” explained maize breeder Cosmos Magorokosho.

The field day was followed by a feedback session and a technical seminar on the maize lethal necrosis (MLN) disease that has emerged recently in East Africa. During the seminar presented by Magorokosho and MacRobert, principal director of the Department of Agriculture Research Services Danisile Hikwa expressed her appreciation to CIMMYT for its efforts to develop MLN resistant varieties.

Controlling maize storage in Kenya: what really works?

Written by on April 27, 2013. Posted in News.

As traditional storage methods are proving less efficient, especially when faced with pests, a team of scientists from CIMMYT and the Kenya Agricultural Research Institute researched the effectiveness of hermetic systems in controlling maize storage pests in Kenya. To identify the most effective system, CIMMYT’s Hugo De Groote, Simon C. Kimenju, Fred Kanampiu, Tadele Tefera, and Jon Hellin, and KARI’s Paddy Likhayo, tested metal silos and super grain bags at three sites in Kenya and concluded that it is technically feasible to control storage insects without insecticides in Africa by using hermetic storage. However, several unanswered questions remain:

While metal silos are very effective, they are also expensive. An economic analysis is necessary to determine the size at which silos become economical. Similarly, if super grain bags get perforated during the storage period, they can be used only once. If that is the case, what is their cost compared to other methods in the long run?
The speed of oxygen depletion needs to be measured. Is oxygen depleting slowly in the super grain bags, thus allowing some insects to survive and perforate the bags from inside? Or did the larger grain borer found in the bags perforate the bag from outside? Answers to these questions are crucial for further steps in grain protection: if the insects survive slow oxygen depletion, it is necessary to find measures to speed up the process; if the insects perforate the bags from outside, additional protection is needed.
Considering the pros (effective) and cons (costly) of metal silos, and the potential onetime- use-only quality of super grain bags, the authors considered the use of plastic rainwater tanks, which are very popular in Kenya and substantially cheaper than metal silos. Further research is needed to determine whether the larger grain borer would drill through the plastic.

Agrovegetal and CIMMYT renew alliance

Written by on April 26, 2013. Posted in News.

On 12 April 2013, CIMMYT director general Thomas Lumpkin and José Ortega Cabello, chairman of the Campo de Tejada cooperative in Spain, signed a five-year extension of a collaborative agreement between Agrovegetal S.A. and CIMMYT dating back to 1998. The objective of the agreement is to develop improved durum wheat, bread wheat, and triticale varieties.

Agrovegetal is an association of several farmer cooperatives and other entities, whose objective is to offer quality seed to farmers in the Andalucía region of Spain. To that end, it channels resources and efforts towards strategic research and development priorities and activities aimed at developing improved varieties.

Ortega Cabello, Ignacio Solís Martel, Agrovegetal’s technical director, and Rafael Sánchez de Puerta Díaz from the Andalucian Federation of Agricultural Cooperatives, met with Hans Braun, CIMMYT’s Global Wheat Program director, to define the specific durum wheat, bread wheat, and triticale research activities that will be conducted to develop high-yielding, highquality, drought-tolerant, and disease-resistant varieties.

Among the alliance’s successes to date is the development of materials with high yield stability and resistance to downy mildew and leaf rust, as well as durums with high pasta-making quality and bread wheats with good baking quality and yellow rust resistance. It has also produced triticales with high protein content, high specific grain weight, and resistance to foliar diseases (downy mildew, rusts, and septoria).

Agricultural Innovation Systems: what do they mean to the work we do?

Written by on April 25, 2013. Posted in Features.

On daily basis, we interact with farmers, extension workers, researchers, seed companies, government officials, and many others. Our work would not be possible without these actors, many of whom focus on bringing new products, new processes, new policies, and new forms of organization into economic use. In their attempts to bring about change in agriculture, these multiple stakeholders are all part of what may be seen as agricultural innovation systems (AIS). However, CIMMYT’s engagement with AIS and its role within innovation platforms was not discussed more closely until recently. To review CIMMYT’s role and current approach to the AIS framework, summarize what has been done, and touch upon future plans, CRP MAIZE, the Global Conservation Agriculture Program (GCAP), and the Royal Tropical Institute (KIT) organized a workshop on “Agricultural Innovation Systems: what does it mean to the work we do?” The day-long event took place at CIMMYT-El Batán on 11 April 2013; it was attended by over 30 participants from several CIMMYT departments, programs, and regional offices, and facilitated by Remco Mur and Mariana Wongtschowski from KIT.

What led to this cooperation between KIT and CRP MAIZE? When presented with the challenges of CRP MAIZE, such as lifting 10 million people out of extreme poverty in 10 years, David Watson, CRP MAIZE program manager, realized that innovations systems and innovation platforms are often seen as key in achieving these high-aiming goals. “I looked on the ground, but there was no explicit agricultural innovation expertise,” Watson said, explaining why CRP MAIZE contacted KIT to take stock of innovation platform structures and operation processes in CRP MAIZE projects, and suggest ways to strengthen the AIS approach and multi-stakeholder interaction structures.

Wongtschowski presented some of the KIT report findings. Addressing the strong technology focus of CIMMYT, she stressed that innovation is not only about developing technology, but also about setting up mechanisms that would put the technology into practice. “Innovation emerges from interaction,” Wongtschowski added, casting more light on the potential role of CIMMYT, “and while researchers may play a role, their role isn’t the most important one.” Jens Andersson, CIMMYT innovation systems scientist based in Zimbabwe, provided a reflection on the KIT report focusing on the implications of adopting an AIS framework for CIMMYT’s organization of research and its partnerships. “At CIMMYT, we look at innovation platforms as a means to reach impact at scale, or as a vehicle for technology transfer,” he said; but, as the report states, feedback loops from farmers and other stakeholders back to the researchers are often missing. At the same time, innovation platforms play a key role in articulating demand for research within the AIS framework. Yet, as Andersson pointed out, there are a number of problematic assumptions about how stakeholders interact within such platforms. For example, it is generally assumed that once an innovation platform has been established, stakeholders can voice their demands. “We have to be wary of those who talk very little,” Andersson said, alluding to the often silent majority of women farmers in meetings. “They might talk little because they can’t express their ideas,” he explained, pointing to the continued role of research in identifying demand. Then he followed with a photograph from first-year on-farm trial plots under conventional ridgeand- tillage and conservation agriculture in southern Africa. Against all expectation, the maize on the conservation agriculture plot was significantly taller than the conventionally grown maize, despite the same fertilizer regime and the absence of soil cover and nitrogen-mineralizing soil tillage in the conservation agriculture treatment. Behind this mystery lies another assumption about stakeholder participation: are farmers participating in researchers’ field trials because of their keen interest in a technology package, or do they have other reasons? In this case, the trialhosting farmer ‘helped’ the researcher by deliberately planting the conventional treatment late so that the researcher’s treatment would look better. The farmer sought to secure the farm inputs supplied to him also for next season. In this area, farmers’ biggest struggle is to source expensive inputs, notably fertilizer, and the input-supported trials of the researcher provided an opportunity. Farmer participation was thus motivated by a constraint beyond the field scale. “If we don’t research and understand how the wider system works, we can’t effectively introduce new technologies,” Andersson concluded his argument for a system-oriented research.

The workshop’s morning section was wrapped up with a group discussion on the changes necessary for successful innovation. Participants discussed and presented their ideas on what could be improved in our daily work regarding AIS. One question recurred several times during the lively discussions: is it our role to always be the facilitator within innovation platforms, or should this role be carried out by farmers’ associations or other actors?

The afternoon session was devoted to presentations by Bram Govaerts, leader of the Take it to the Farmer component of MasAgro, and Michael Misiko, GCAP innovation specialist, who focused on innovation platforms and their components within Take it to the Farmer and SIMLESA, respectively. While providing an overview of Take it to the Farmer, Govaerts stressed the importance, complexity, and history of farmer organizations as parts of agricultural innovation systems, reiterating Andersson’s previous statement on the importance of understanding the system. Misiko focused on the forms of and need for innovation platforms within SIMLESA. The foundations of SIMLESA lie on integration and partnerships of systems and institutions, sustainable innovation, and impact. However, the organizations operating within SIMLESA are often poorly clustered, sometimes completely detached from the commodities with which they work. According to Misiko, the next step towards further efficiency of the project is a higher level of integration of institutions within SIMLESA’s innovation platform systems.

Bruno Gerard, GCAP director, and Watson, concluded the workshop with reflections on AIS and their roles. “Innovation platforms and innovation approaches should not be taken as the next silver bullet to achieve impact scale,” said Gerard. “They are a mean rather than an end. They are critical for better understanding of social processes within farming systems and for putting technical innovations in context as they can provide important missing knowledge for researchers, farmers, and other actors, including the private sector, in a co-learning fashion.” Gerard pointed out some of the drawbacks as well; innovation platforms and approaches are often resource-intensive and difficult to scale out and scale up due to their context-specificity. “But they can generate valuable, more generic lessons on adoption, adoptability, and the way forward,” he added. “As researchers we have to be careful to intervene more as a catalyst and honest broker and not be too central in order to achieve positive long-term changes. We have to think of a good exit strategy from the beginning. At GCAP, innovations approaches are one piece of the puzzle within our systems research framework and impact pathways,” Gerard concluded.
