Even in the best years, significant swathes of sub-Saharan Africa suffer from recurrent drought. Drought wreaks havoc on the livelihoods of millions of Africans – livelihoods heavily leaning on rain-dependent agriculture without irrigation, and with maize as a key staple. And that is not all: drought makes a bad situation worse. It compounds crop failure because its dry conditions amplify the susceptibility of maize in farmers’ fields to disease-causing pests, whose populations soar during drought.

Providing maize farmers with context-specific solutions to combat low yields and chronic crop failure is a key priority for CIMMYT and its partners, such as those in the Water Efficient Maize for Africa (WEMA) Project.

“Our main focus is to give famers durable solutions,” remarks Dr. Stephen Mugo, CIMMYT Regional Representative for Africa and a maize breeder, who also coordinates CIMMYT’s work in WEMA. “These seeds are bred with important traits that meet the needs of the farmers, with ability to give higher yields within specific environments.”

Farmers in Kenya, Uganda, Tanzania and South Africa will soon access WEMA’s high-yielding drought-tolerant maize hybrids. In total, 13 hybrids were approved for commercial production by relevant authorities in these countries. These approvals were spread between October 2014 and March 2015 in the various countries.

Kenya’s National Variety Release Committee (NVRC) approved four hybrids in February 2015 (WE2109, WE2111, WE2110 and WE2106), while neighboring Uganda’s NVRC also approved four hybrids at the end of 2014 (WE2101, WE2103, WE2104 and WE2106). Across Uganda’s southern border, in March 2015, the Tanzania Official Seed Certification Institute approved for commercial release WE3117, WE3102 and WE3117. Still further south, South Africa’s Department for Agriculture registered two hybrids (WE3127 and WE3128) in October 2014.

In each country, all the hybrids successfully underwent the mandatory National Performance Trials (NPTs) and the Distinctness, Uniformity and Stability (DUS) tests to ascertain their qualities and suitability for use by farmers.

Varieties that pack a punch
In Kenya, these new WEMA varieties boast significantly better yields when compared to varieties currently on the market as well as to farmer varieties in drought-prone areas of upper and lower eastern, coastal, central and western Kenya.

And that is not all: across them, the new hybrids also have resistance to rampant leaf diseases like maize streak virus, turcicum leaf spot and gray leaf spot.

Dr. Murenga Mwimali of the Kenya Agricultural and Livestock Research Organization, who is also WEMA’s Country Coordinator in Kenya, explains: “These hybrids are expected to give farmers an average yield of three tonnes per hectare in moderate drought and eight tonnes in good seasons. These are better seeds that will help Kenyans fight hunger through increased productivity.” According to the UN Food and Agricultural Organization, Kenya’s national average productivity in 2013 was a meager 1.6 tonnes per hectare. This compares poorly with South Africa’s 6 tonnes, Egypt’s 9 tonnes and USA’s 9–12 tonnes, as generally reported in other statistics.

Where to find them
The seed of these new varieties should be available in the market once selected seed companies in Uganda and Tanzania produce certified seeds by end of August 2015.

Dr. Allois Kullaya, WEMA Country Coordinator in Tanzania, applauded this achievement and the partnership that has made it possible. “Through the WEMA partnership, we have been able to access improved seed and breeding techniques. The hybrids so far released were bred by our partner CIMMYT and evaluated across different locations. Without this collaboration, it would not have been possible to see these achievements.” said Dr. Kullaya.

In South Africa, close to 10,000 half-kilo seed packs of WE3127 were distributed to smallholder farmers to create awareness and product demand through demonstrations to farmers and seed companies.

This seed-pack distribution was through local extension services in the provinces of Eastern Cape, Free State, KwaZulu–Natal, Limpopo, Mpumalanga and North-West.

Three seed companies also received the hybrid seed to plant and increase certified seed for the market.

Where it all begins – the CIMMYT ‘cradle’, crucible and seal for quality assurance
“In the WEMA partnership, CIMMYT’s role as the breeding partner has been to develop, test and identify the best hybrids for yield, drought tolerance, disease resistance and adaptability to local conditions,” says Dr. Yoseph Beyene, a maize breeder at CIMMYT and WEMA Product Development Co-leader.

To do this, more than 10, 000 new hybrids combinations are evaluated each year to identify new hybrids that will perform most consistently in various conditions. Hybrids that look promising are subjected to a rigorous WEMA-wide area testing. Only those that pass the test get the CIMMYT nod and ‘seal of approval’. But the tests do not end there: for independent and objevhe verfication, the final test  is that these select few advance to  – and are submitted for – country NPTs.

Dr. Beyene explains: “Because of these rigorous testing, hybrids that are adapted in two or three countries have been identified and released for commercial production to be done by regional and multinational seed companies which market hybrids in different countries. This eases the logistics for seed production, distribution and marketing.”

How to recognize the new varieties – distinctive shield against drought
All the hybrids released under the WEMA project will be sold to farmers under the trade-name DroughtTEGO™. ‘Tego’ is Latin for cover, protect or defend. The African Agricultural Technology Foundation (AATF), which coordinates the WEMA Project, has sub-licensed 22 seed companies from the four countries to produce DroughtTEGO™ seeds for farmers to buy.

WEMA’s achievements are premised on a powerful partnership of scientists from CIMMYT, national agricultural research institutes from the five WEMA target countries (Kenya, Tanzania, Uganda, Mozambique and South Africa), AATF and Monsanto.

WEMA is funded by the Bill & Melinda Gates Foundation, the United States Agency for International Development and the Howard G. Buffet Foundation.

Farmers in Chuadanga District of Bangladesh have been using a unique local method to store their maize: the gola.

Golas are large rectangular or cylindrical containers used to store seed and animal feed. In Bangladesh, golas are traditionally used to store paddy rice. They are made locally using bamboo for the sides and tin for the roof, can last up to 80 years and hold from 2 to 20 tons of grain.

Many Bangladeshi farmers believe that, unlike rice, maize grain cannot be stored in golas due to its high susceptibility to insects and pests. To keep its quality from deteriorating, farmers normally sell maize grain at a minimum price as quickly as possible after harvest.

Unlike most of the country’s farmers, Chuadanga farmers use golas to store maize grain until its market price goes up, which results in higher profits. According to a recent CIMMYT-Bangladesh survey, the longer they store the seed, the higher the profit. “The profit earned by the Chuadanga farmers through maize grain storage helps to increase the national per capita income, allowing Bangladesh to become a middle income country,” said Prodip Hajong, Senior Officer in Agricultural Economics at the Bangladesh Agricultural Research Institute (BARI).

Eighty percent of all maize grain produced in Chuadanga is stored anywhere from 4 to 43 weeks and sold for a higher price. According to the survey, golas were the preferred storage for maize and used by over 60% of respondent households. Each household earned a profit of approximately USD $389.68 in 2012, USD $315.64 in 2013 and USD $130.19 in 2014. During 2014, the overall market price of maize grain was low compared to previous years; that is why farmers’ profit margin was comparatively small.

“High temperatures inside the gola help maintain grain quality by killing insects, their larvae and eggs,” said Abdul Momin, CIMMYT Cropping Systems Agronomist. With assistance from the Cereal Systems Initiative in South Asia in Bangladesh (CSISA-BD) project, Chuadanga farmers have been modifying their golas – for example, by reinforcing the floors with tin to prevent post-harvest losses from rodents and insects – so that they can store maize for longer periods.

The CIMMYT-Bangladesh survey was conducted by CIMMYT researchers Frederick Rossi, Agricultural Economist; Elahi Baksh, Applied Agricultural Economist; Abdul Momin, Cropping System Agronomist; Thakur P. Tiwari, Country Representative in Bangladesh and Prodip Hajong, Senior Officer in Agricultural Economics at BARI. They recommended making an action plan in collaboration with the Department of Agricultural Extension, BARI and local NGOs, to demonstrate and disseminate this low cost technology throughout the country.

Littri Gaun is a characteristic remote, hilly village in Dadeldhura district of Nepal. Relatively low agricultural yields, soil erosion and labor out-migration are major challenges for monsoon-dependent agriculture in this region. During the kharif season, farmers mostly grow the dominant staple crops – unbunded upland rice and maize. Some farmers also practice maize-soybean mixed cropping because soybean fetches a good price in the market. Finger millet is also grown for home consumption in some areas during kharif.

Farmers in Littri Gaun believe that chemical fertilizer can destroy soil, and use only farmyard manure and plant litter to enrich their soil. Low nutrient levels — particularly for Nitrogen – have led to consistently low crop productivity. Moreover, farmers grow traditional local varieties for which seeds may have been saved for several years, as seed replacement rates are low. With men migrating outside for work, women are left responsible for the agricultural production, as well as household duties, resulting in high levels of drudgery for women and high labor constraints during peak agricultural times.

CIMMYT led Cereal Systems Initiative for South Asia in Nepal (CSISA-NP) began working with farmers in Littri Gaun in 2012 and facilitated farmers in the village to form a group called “Ugratara Agriculture Group.” CSISA works with Ugratara to introduce new, suitable crop varieties, better-bet agronomic practices and small-scale machinery that women can use.

CSISA and Ugratara have conducted several maize trials to screen and grow different registered hybrids, to evaluate different crop establishment methods and to experiment with different methods of fertilizer management. Trials showed that hybrid maize yields were more than double to those of the local varieties under the same management conditions. With hybrids, Ugratara has even harvested up to three times the yield of the local maize varieties. Among the genotypes tested, group members preferred Kanchan-101 (hybrid) because of the high and early yields. Trials also showed that the local maize variety produced higher yields when fertilizer was applied, demonstrating the importance of good nutrient management.

During a farmers’ field day, Ugratara group members expressed that improved varieties like the maize variety Kanchan 101 (hybrid), introduced by CSISA, are more productive than their local maize. Ugratara group member, Naresh Khadka said, “We are producing more than double using the hybrid Kanchan-101 and it’s ready early than the local variety.” For upland rice, trials also showed that the appropriate use of chemical fertilizers nearly doubled yields of local rice varieties and that chemical fertilizer increased yields over those achieved through the application of farmyard manure.

CSISA also introduced improved varieties of lentil, which has increased the number of farmers producing lentil, lentil yields, and household lentil consumption. Farmers have also been able to sell their surplus lentil production in the market for NRs. 150/kg. “After seeing the benefits of improved lentil variety, more farmers are now expanding their area under lentil cultivation,” said Khadka.

Finally, CSISA introduced small machines like the mini tiller and the jab planter, which helped women to prepare and cultivate land, making them more self-sufficient, saving their time and helping them to adapt better to labor shortages. Women in Littri Gaun are not allowed to plough land with bullocks, as it is considered to be men’s work. Saru Khadka, a lady member of Ugratara group, said, “By using minitiller for preparing our fields, we don’t have to depend on men for labor and bullocks.” Participation in Ugratara has helped the group’s women members to feel empowered. Khadka acknowledged that women in Ugratara have learned to confidently express their views and problems to relevant authorities and they feel more capable and assertive now.

 

 

A delegation of 15 Nepalese seed entrepreneurs learned about various business models and innovations for seed industry development on their first visit to India. The visit, sponsored by the Cereal Systems Initiative for South Asia in Nepal (CSISA-NP), lasted from 1 to 10 June.

According to Arun Joshi, Country Liasion Officer, CIMMYT-Nepal, Nepalese seed companies are in their initial growth phase and constrained by the lack of research and development, low business volume, limited seed processing and storage facilities, and low seed capital. To help them overcome these challenges, CSISA-NP recently initiated a business mentoring initiative to build the capacity of small and medium enterprises engaged in wheat and maize seed production.

A team of CSISA-NP experts assessed the potential and challenges of Nepalese seed companies and established a good relationship with them. “After the assessment, 15 Nepalese cereal seed production entrepreneurs from Nepal’s hills and Terai (plains) were identified for a ten-day visit to India,” reported Dilli K.C., Monitoring and Evaluation Specialist, CIMMYT-Nepal.

During the visit, the Nepalese delegation observed many Indian seed business components including research and development programs, seed processing facilities and government farms at four major seed enterprise centers: Delhi, Kashipur, Hyderabad and Elluru.

The entrepreneurs received first-hand information on ways to link contract farmers with private companies, how to set up linkages for hybrid seed production, and how to enhance maize seed germination through cob drying. “We have to establish demos of our products and maintain good relations with seed producers and consumers,” said entrepreneur Tikaram Rijal, Managing Director, Global Agri-Tech Nepal Limited, after the visit.

The participants also learned how smaller seed companies that work with open-pollinated varieties can maintain seed quality and market their brand. “For our growth and sustainability, R&D activities should be promoted even in open-pollinated seeds,” said one of the participants, Subhas Upadhaya, Chairperson, Lumbini Company.

India’s private sector shared the strategies they had adopted to manage challenges during their growth period and showed a willingness to help build the capacity of Nepalese seed enterprises through internships, short-term training and collaborative research.

During discussions with the National Seed Association of India (NSAI), the visitors learned about the role seed associations play in the growth of a country’s seed industry and in implementing seed policies. A memorandum of understanding was signed between NSAI and Seed Entrepreneurs Association of Nepal (SEAN) to foster better collaboration between seed companies from both countries.

“The visit and participants’ interaction with Indian seed companies helped them realize the importance of having a clear strategy both for SEAN and their individual businesses in order to be more successful,” added Joshi. CSISA-NP will continue to strengthen its collaboration with seed enterprises and guide them in developing their business plans, according to Andrew McDonald, Project Leader, CSISA-NP.

Guest blogger from HarvestPlus

Only 20 years ago, the idea that maize could reduce vitamin A deficiency (VAD) would have been summarily dismissed. Agricultural scientists were focused on increasing yields and developing more robust varieties that could withstand the constant assault of new pests and diseases. The idea of making maize and other staple food crops more nutritious by breeding in vitamins and minerals, a process called biofortification, was a novel concept. However, with the launch of HarvestPlus in 2003, a collaborative research partnership was launched to bring together scientists across disciplines in an effort to reduce hidden hunger caused by micronutrient deficiencies. One of the fruits of this partnership were the world’s first “orange” maize varieties rich in vitamin A. This ‘orange’ vitamin A maize has been conventionally bred to provide higher levels of provitamin A carotenoids, a naturally occurring plant pigment also found in many orange foods such as mangoes, carrots and pumpkins, that the body then converts into vitamin A.

I sat down with two of the scientists who have been integral to this global effort: CIMMYT’s Dr. Kevin Pixley, who led the first 10 years of HarvestPlus’ maize biofortification project while heading CIMMYT’s breeding program for vitamin A maize, and Dr. Fabiana Moura, a nutritionist with HarvestPlus who oversees all vitamin A-related research. The question on my mind was: what does it take for scientists to break out of their disciplinary strait jackets and to look at a food with a rich and storied history thorough a different lens?

Kevin, where did the idea of making maize more nutritious come from?

Nearly a billion people eat maize as a staple food, and many of them are poor and malnourished. Maize is a great source of energy, but its protein is deficient in essential amino acids and crucial minerals and vitamins. Of course, everyone should eat a balanced, healthy diet, but poverty gets in the way. Chronic malnutrition is unacceptably common among some populations that depend heavily on staples such as maize in their diets and can’t afford more nutritious foods. Improving the nutritional quality of maize is a way to improve the health and livelihoods of many maize consumers.

Fabiana, why vitamin A in particular?

Vitamin A is essential for good vision, growth, and a healthy immune system. But, 190 million children under 5 and 19 million pregnant women are vitamin A deficient. To combat this, the World Health Organization recommends vitamin A supplementation in infants and children aged 6 months to 5 years, and the capsules are distributed every 6 months. The fix, however, is temporary. The improved vitamin A status lasts less than 2 months before wearing off, failing to cover the 6-month period. It is also not a sustainable strategy, with high costs that can affect its coverage.

Under this scenario, providing vitamin A through a typical diet is a more sustainable way to address the VAD problem. In countries like Zambia where people eat a lot of maize, orange maize could provide half of the daily vitamin A requirement. Safety is another important aspect. The provitamin A in the maize is converted to vitamin A in the body as it is needed. Supplements and fortified foods provide preformed vitamin A that, if ingested in higher doses, could cause toxicity because they accumulate.

Lastly, the orange maize will be eaten by the entire family. Women of childbearing age will enter pregnancy with a better vitamin A status and maintain this level during pregnancy. Newborns will receive the vitamin A from orange maize through their mothers’ breast milk. Everyone wins.

And, Kevin, what was the biggest challenge in breeding orange maize?

The first challenge was finding maize with high levels of provitamin A carotenoids for use in breeding efforts. They are found in a lot of foods but we had not looked in maize before.
We then needed the expertise of biochemists and geneticists to develop essential laboratory methods to precisely and affordably identify the few plants with the highest amounts of these desired carotenoids from among many thousands of plants created each year in the breeding projects at CIMMYT, IITA and elsewhere. As in every applied breeding program, orange maize breeders need to continually monitor, improve and combine dozens of characteristics – high yield, disease resistance, good food processing ability, taste, etc., into new varieties that farmers and consumers will prefer over those that they currently grow and eat. As we speak, CIMMYT, IITA and other maize breeders are working intensely to maintain a full “breeding pipeline” to continually improve upon current successes. Soon, there will be new varieties with 50% more provitamin A than those first commercialized 2-3 years ago. And there are varieties in the pipeline with double the amounts of provitamin A that will improve the nutrition and lives of farmers and consumers in decades to come.

What was the biggest challenge in working with someone from outside of your discipline?

Fabiana: Learning an entirely new vocabulary of OPVs [that’s open pollinated varieties], hybrids, etc. It was like learning a foreign language!
Kevin: My own ignorance about the complexities and importance of diverse disciplines to the success of our team; I’d never worked with nutritionists in plant breeding before. It is great fun and a big challenge to learn about other disciplines, especially human nutrition, food technology and public health, but also biochemistry, economics and even politics. A big challenge for the whole team was learning to trust the other disciplines to do their part of the job, knowing that every chain is only as strong as its weakest link.

Have any assumptions or perspectives that you had about the other discipline changed as a result of working together?

Fabiana: I learned that agriculture also faces some challenges. When planting maize for a feeding trial study I remember asking Kevin if he could assure us that there would not be major issues to deal with. His reply was, “there could be a pest infestation that has not happened for the past 20 years–so we cannot predict what might happen. We have had cases with typhoons that wiped out an entire field.” That was when we decided to have 2 two fields in 2 different provinces planted with vitamin A maize to ensure we would have enough material for the study.

Kevin: I always thought that nutrition was an exact science; I was very wrong! Nutrition is very complex; everything depends on multiple factors. Even the effectiveness of vitamin A maize depends on health status, age, other diet components, and many other factors.

Kevin, what changed about your own work as a result of working with nutritionists?

I had to accept that the goalposts would move. Many scientific assumptions fell away and were replaced with new ones. It continues to be an eye-opening experience because important discoveries are being made every year. There are many important factors to consider, e.g. which provitamin A carotenoids are most helpful nutritionally, which conversion factors must be applied when “translating” how much provitamin A content in the maize grain is needed to be useful for the consumer, how much of the provitamin A in the grain will be lost (degraded) when the maize is cooked, and more! These factors determine the amount and forms of provitamin A that we have to breed into the maize in order to improve nutrition when people cook and eat the crop.

My experiences working with nutritionists have broadened my vision about the role of plant breeding in agriculture for nutrition, health and improved livelihoods.

Fabiana, what evidence do we have that this works?

We know that the provitamin A from maize is efficiently absorbed and converted into vitamin A in the body. One study conducted in a rural setting in Africa showed that the vitamin A body stores of 5-7 year-old children improved when they ate orange maize—similar to the effect of vitamin A supplements. We also have some preliminary data demonstrating that children who ate orange maize for 6 months experienced improved capacity of the eye to adjust to dim light. That indicates an improvement in night vision, a function dependent on adequate levels of vitamin A in the body. Another study is looking at the impact of orange maize on the vitamin A status of lactating mothers and their breastfed children. In particular, we will learn how much the vitamin A contribution to the breastfed child will come through the breast milk of mothers who are fed the orange maize and how much will come from the orange maize itself that is fed directly to the children (only those above 6 months of age will be fed orange maize). All the studies cited above are using innovative and cutting edge technology applied in rural settings in Africa. They have been conducted in over 50 feeding sites and greatly facilitated by local people like Mrs. Donata Kalunga (standing next to me in the picture), who offered her school for disabled children as a kitchen and site for training and clinical assessment for the study. I’m optimistic that in the next year or two when we get the full results of ongoing studies, we will find that they reinforce the positive outcomes we’ve found so far.

Go back to A Grain a Day

The good news: by 2050, world population growth will likely fall to half or less the rate of 1.7% per year witnessed over the last half of the 20th century, offering a glimmer of hope for humanity to feed itself sustainably. More troubling though is that agricultural productivity growth is also slowing in many parts of the world, often because of declining investments in farm productivity-oriented research and political indifference. Which competing trend will win out in the end?

Attempting to answer this critical question and shed light on the causes, Philip G. Pardey, Professor of Science and Technology Policy, University of Minnesota, spoke to a global gathering of CIMMYT scientists in Mexico on 15 June. His presentation gave evidence and conclusions from recently published research¹ to develop and apply the new “International Agricultural Prospects” model that projects global agricultural consumption and production to 2050.

Looking at U.S. trends over the 20th Century, Pardey said that agricultural productivity grew quickly until 1990 but the pace of growth slowed afterwards by more than half. “Data from 1910 show a curvilinear trend featuring a productivity surge in the 1950s-70s,” he explained. “This U.S. surge might be illustrative of a more general one-time phenomenon in many agricultural economies around the world. This includes widespread uptake of agricultural chemicals, improved seeds, fertilizer and other modern inputs, and a massive movement of labor out of the sector.” The implication, he said, was a need to double down on sustainable agricultural productivity growth including giving increased attention to research that maintains past productivity gains.

Other conclusions from Pardey included:

• Think long-term: it takes decades to go from an idea to a commercialized farm technology.
• The basic political economy is driving investments away from farm productivity.
• Population and demographics are major determinants of the consumption of agricultural output.
• Additional demand for biofuels may not have as dramatic an effect on food futures as some speculate.
• Available agricultural land appears more than sufficient for the projected growth in food production.

Regarding consumption, the model factored in consumption of biofuels, human food and animal feed, while considering changes in population growth, per capita income, and demographics — most notably the aging of the planet’s population. “We expect worldwide average per capita incomes in 2050 to be at the levels of more prosperous countries in 2000, but with a big spread among regions of the world,” said Pardey. “There will be encouraging reductions in people below the poverty line, but major clusters of the poor will persist in South Asia and Sub-Saharan Africa.” He also observed that increased life expectancies and numbers of the elderly in countries like China would reduce the demand for calories and change the structure of diets.

The driving factors used to forecast production included the pace of crop yield growth in different regions around the world, the location and availability of agricultural land, and its agro-ecological suitability for growing specific crops. “In the U.S., the ‘average’ maize plant has moved 279 kilometers north and 342 kilometers west since 1910,” he explained. “From 16 to 21 percent of the growth in U.S. maize output is attributable to this movement.”

Across Ethiopia, farmers bring a different dimension to the age-old tradition of naming children in symbolic and meaningful ways, by assigning a human name to Quality Protein Maize (QPM) that reflects its importance. In some parts of Oromia region, QPM is known as Gabissa, meaning builder, because it is believed to build bodies and make people strong. In the Amhara region, it is known as ‘Almi Bekolo’ or ‘Gembi bekolo, both names meaning building the body.  QPM has gained its fame across Ethiopia, as an affordable and viable option to alleviate protein malnutrition and reduce animal feed costs thanks to the CIMMYT’s Nutritious Maize for Ethiopia (NuME) project and many national partners.

QPM looks and tastes the same as normal maize but contains up to twice as much of the essential amino acids, lysine and tryptophan. Eating QPM is beneficial for children who survive on a maize-dominated diet. According to a study in Food Policy children who consume QPM benefit from 12% increased weight and 9% increased height.

Commitment to the agriculture sector

Around 10% of the Ethiopian national budget has been allocated to agriculture, according to the Ministry of Agriculture. As a result, the agriculture sector, which accounts for roughly 43 per cent of overall GDP, has been registering steady progress over the past two decades, landing the country on a path to food security. A number of other measures have contributed to this success, such as the availability of fertilizer, improved seed and agricultural extension services, which have currently reached more than 8 million farmers.

A focus on nutrition security

The Ethiopian government is currently stepping up nutrition interventions targeting women and children, with aims for a 3% annual reduction in the number of stunted and underweight children, according to the Government’s five-year Growth and Transformation Plan. However, the fact that 2 out of every 5 children in Ethiopia are stunted and 28% of all child mortality in Ethiopia is associated with undernutrition or malnutrition, is a clear indication that a lot still needs to be done.

To tackle the challenge of malnutrition in Ethiopia, CIMMYT takes a holistic approach to QPM and conducts a range of activities including: improved crop management practices, post-harvest handling and processing, increasing the participation of women, nutrition campaigns, as well as strengthening institutional capacity. Since 2012, 143,747 farmers, extension workers and development officials (of which 28% are women) have attended 993 field demonstrations and 240 field days on QPM utilization.

Funded by the Canadian Department of Foreign Affairs, Trade and Development, CIMMYT is working with the Ethiopian Institute of Agricultural Research, the Ministry of Agriculture and other partners to improve food and nutritional security in Ethiopian farming communities through the promotion and expansion of QPM backed by improved agronomic practices that increase productivity. NuME is building on the success of previous CIMMYT projects to bring QPM to rural maize producers in the Ethiopian maize belt and beyond where consumers, especially young children and women, are at risk of lysine deficiency.

Derek Byerlee, former director of the CIMMYT economics program (1987-94) and current visiting scholar at Stanford University and adjunct professor at Georgetown University, presented some of his latest research at a brown bag lunch at CIMMYT headquarters on 1 May. His presentation, “Growing Land Scarcity, the Borlaug Hypothesis and the Rise of Megafarms,” examined the economic and environmental benefits and repercussions of cropland expansion, the recent rise of agribusiness and the delicate balance between crop intensification and deforestation.

The “Borlaug Hypothesis” is the idea that increasing crop yields can help prevent cropland expansion and deforestation, thus alleviating hunger and poverty without dramatically increasing environmental impact. Developed by the legendary Nobel Prize Laureate and CIMMYT scientist Norman Borlaug, the postulate is controversial in environmental circles, and some researchers have published studies showing that higher crop yields in the tropics increase incentives to clear forests, thus making investments in crop research potentially counterproductive to sustainable growth.

Byerlee noted that the world has increased per capita cereal production by about 40 percent over the last 50 years on about half the arable land per capita that it used in 1961. Models developed by Byerlee and his associates show that, without CGIAR work since 1965 to develop improved crop varieties, the land area devoted to food crops would have increased by 18 to 27 million hectares, mostly in developing countries. Byerlee supports Borlaug’s claim that broad-based investment in crop research and development indeed contributes to saving the world’s forests, although estimates by Byerlee and his associates are an order of magnitude lower than those of Borlaug.

Investment in crop intensification may be more important than ever, as the world’s growing population demands ever-growing quantities of food and land. “Meta-analysis of demand estimates suggests that, given current yield trends, agriculture will require an additional 200 to 450 million hectares of land by 2030 — as much as the entire combined land area of India and South Africa,” Byerlee said. At the same time, Byerlee found that an estimated 450 million hectares of land could be available for crop expansion but is concentrated in just a few countries and its cultivation could have negative impacts on the environment and on people already using that land for other purposes.

Linked to the question of where crops should be cultivated is the issue of who will cultivate them, especially on the land frontier. Byerlee described the recent rise of “megafarms” run by agribusiness companies and examined their economic benefits (or lack thereof) in comparison to traditional family farms that still prevail across the world. Byerlee argued that family farms were more efficient, equitable and contribute to more growth than megafarms, which benefit from professional management and technologies that allow for larger scale but do not display significant cost advantages over traditional family farms. Byerlee ultimately recommends models that combine agribusiness and smallholder farms for best results.

We have come a long way when it comes to obtaining aerial images of our research sites. My colleagues and I once used helium-filled balloons and twin cameras to obtain infrared and color images in an all-day operation; now we use unmanned aerial vehicles (UAVs) fitted with high-resolution lenses and multispectral cameras to take dozens of images over large areas in a matter of minutes.

Farmers and researchers need to know every square meter of their fields, to determine spatial variability, take remedial action and implement adaptive controls and responses. UAVs can achieve this without anyone setting foot in the field. In an era where we are time- and resource-poor, we can accurately assess the health of entire fields in mere minutes, which could have an enormous impact on agriculture.

However, in Northwestern China, the notion of using UAVs to take aerial pictures in an agricultural setting evokes suspicion, elicits numerous questions and is extremely novel.

As a result, we have to provide detailed explanations and gain permission from a number of local authorities before we can undertake what is a simple non-invasive task that would normally go unnoticed on a farm in Australia or Mexico.

CIMMYT-China’s Global Conservation Agriculture Program (GCAP) and the Ningxia Academy of Agricultural Sciences obtained permission from the Wuzhong City Agricultural Mechanization Bureau to fly a UAV. Earlier this month, my colleague Mr. Zhang Xuejian, Director of the Information Research Institute, enlisted a local UAV operator to take images of conservation agriculture, relay cropping and wheat variety trials at a demonstration site near Wuzhong City in Ningxia Hui Autonomous Region.

Although the Information Research Institute has a fixed-wing UAV with sophisticated imagery equipment, the system is somewhat dated and requires extensive documentation, a landing strip and up to six operators. However, the GCAP-Ningxia Academy of Agricultural Sciences collaboration recently demonstrated the flexibility, capability and efficiency of a modern, multi-rotary wing UAV that rapidly produces imagery and readily displays agronomic traits, farm management and genetic responses not easily appreciated or identified at ground level. Given the success of this demonstration, we will seek funding to buy a new aircraft and develop proximal sensing and imagery within the region.

Smallholder farmers need accurate, inexpensive, readily-available data to increase production, but have traditionally not had access to precise spatial information due to time, money and labor constraints. UAVs can collect visual, thermal and hyperspectral data, which when analyzed provide a broad range of information that would otherwise be unavailable. UAV imagery can also focus on specific biotic and abiotic issues such as diseases, crop stress and farm management. UAV technology would provide breeders and agronomists in NW China not only a new view of agriculture, but also a new path to achieving increased production and food security, while conserving natural and human resources.

Agricultural research for development must reconcile approaches that place resource-poor farmers at the center, said CIMMYT’s new Director General addressing staff at CIMMYT headquarters near Mexico City on his first day in the new job.

“Our mission at CIMMYT is to use science and innovation to improve livelihoods, particularly in the developing world. Research projects must be centered on the impact in farmers’ fields,” said Kropff, who joined CIMMYT this week from Wageningen University and Research Center in the Netherlands, where he was Rector Magnificus and Vice Chairman of the Executive Board.

The world of agricultural research for development is changing; yields need to increase but increases alone are insufficient, added Kropff. A joint approach based on innovations in breeding, solid agronomy based on precision farming, systems research and innovations in the value chain are all essential to have the greatest impact in farmers’ fields, Kropff continued.

“CIMMYT’s scientific expertise is unparalleled in the public sector, with expertise in breeding, sustainable intensification, genomics, statistics and the social sciences,” Kropff said.

“CIMMYT is the flagship institute within the CGIAR and must be at the forefront of new reforms,” he said. One of his top priorities will be to align CIMMYT with the new CGIAR Strategic Results Framework and the CGIAR Research Programs (CRP reforms). The CGIAR is a 15-member consortium of international agricultural researchers of which CIMMYT is a member and leads the CRPs on MAIZE and WHEAT. Prior to joining CIMMYT, Kropff was member of the Consortium Board.

Standing with his wife, Nynke Nammensma, Kropff opened his address in Spanish to applause. “My job is to listen to you, and hear your vision for CIMMYT as we start a new phase of our journey together,” he said. “It’s important to have a direct connection with all staff and a visible presence”.

During a pilot program with members of the Kisan Sakhi Group in Muzzafarpur, Bihar nearly 350 women farmers were trained on operating the Diesel Engine Powered Open Drum Thresher. In this picture, Suryakanta Khandai (center), postharvest specialist, IRRI, is conducting a demonstration for two of the women’s self-help groups (SHGs) that have expressed interest in purchasing four machines next season.

In India, farmers with large landholdings from prosperous agricultural states like Punjab can buy expensive and sophisticated machines for farm operations. However, resource-poor farmers with smaller landholdings from states such as Bihar may not have funds to buy these machines. “A huge bottleneck exists in terms of time wasted in harvesting and threshing that is preventing timely sowing of crops,” said Scott Justice, agriculture mechanization specialist, CIMMYT.

The Cereal Systems Initiative for South Asia (CSISA) is working to ensure that farmers all along the spectrum of landholdings have access to differently priced and scale-appropriate machinery based on their specific requirements. One of the ways CSISA does this is by improving existing designs of harvest and postharvest machinery to better meet local needs.

For shelling maize, farmers in Bihar could either purchase a very large, highly productive machine that costs approximately US$ 786 or use a handheld maize sheller that is cheap but can only shell 15 – 20 kg per hour. A medium-sized mechanized single cob maize sheller brought to Bihar from Nepal broke the cobs because the sheller had been optimized for Nepal’s hybrid varieties that had longer and thinner cobs. Farmers in Bihar need their cobs to remain intact so they can be used as fuel for their stoves. According to Justice, “These lightweight and affordable shellers are relatively new entrants on the scene. Their simple designs mean that they can be made easily by local manufacturers.” More importantly, they can also be modified as required.

CSISA worked with a local fabricator to modify the existing design and created an electric motor powered double cob maize sheller, which can shell 150 kg maize per hour and consumes only 2 – 4 units of electricity. Priced at US$ 126, the machine is also fairly affordable. “In fact, half the cost of the machine is that of the electric motor alone. For farmers who already own one, the machine would merely cost US$ 63,” said Suryakanta Khandai, postharvest specialist, IRRI, who works for CSISA in Bihar.

Similarly, until recently, farmers in Bihar only had two options for mechanized rice threshing – the very large axial flow thresher that can cost up to US$ 2,700 after subsidy or the compact pedal-powered open drum thresher that has very low capacity and is difficult to operate for extended periods of time.

“Farmers clearly needed a medium-sized, affordable, efficient and portable mechanical rice thresher,” said Khandai. But to build a truly relevant product understanding the shortcomings of the existing options was critical. “The existing models also lacked winnowing or bagging functions, which were included in the new design. Besides giving it wheels, we also decided to use a diesel engine to power the machine to allow for threshing in the field immediately upon cutting, which would help reduce losses.” The result was the diesel engine powered open drum thresher.

It costs US$ 23.96 to hire one person to manually thresh 1 acre of rice in 7 days. Using the diesel engine powered open drum thresher, however, the same area can now be covered in just over four hours at a total cost of US$ 10.54.

Since modifying these medium-sized machines does not offer sufficient profit margin for larger manufacturers and retailers, CSISA approached local fabricators to fill this gap. The maize sheller was customized in cooperation with Dashmesh Engineering, which sells the machine at a profit of US$ 11–13. “Profits help ensure that the fabricators put in efforts on their own to scale out the machines. Other dealers have also expressed interest in the maize sheller, which is great because having multiple fabricators involved ensures that the pricing remains competitive,” said Khandai.

Justice added, “Equipment like powered open drum threshers for rice are very simple but they have not spread very widely. I feel these should now also be promoted with owners of two-wheel tractors and mini tillers in India and Nepal.” Since the thresher can easily be adapted again to be powered by those engines, the cost of the machine can be brought down even further.
