CIMMYT and partners set the pace in maize and wheat research in Africa

Written by on July 27, 2016. Posted in News.

NAIROBI, Kenya (CIMMYT) – The recent inauguration of a new seed storage cold room at the Kenya Agricultural and Livestock Research Organization (KALRO) research center at Kiboko in Makueni County, about 155 kilometers from the capital, adds to the top notch research establishments managed by the national partners in Africa together with the International Maize and Wheat Improvement Center (CIMMYT). This successful partnership continues to help farmers overcome crippling challenges in farming and to realize the yield potential of improved varieties.

Since its establishment in Africa, over 40 years ago, CIMMYT has prioritized high quality research work in state-of-the-art research facilities developed through long-standing partnerships with national research organizations, such as KALRO.

“If CIMMYT were to be established today, it would be headquartered in Africa because this is where smallholder farmers face the biggest challenges. At the same time, this is the place where outstanding work is being done to help the farmers rise above the challenges, and with great success,” said Martin Kropff, CIMMYT Director General during his recent visit to Kenya.

The cold room jointly inaugurated by Kropff, and KALRO Director General, Eliud Kireger will help store high value maize seeds with an array of traits including resilience to diseases, insect-pests and climatic stresses as drought and heat, for up to 10 years, without the need for seed regeneration every year, thereby avoiding risk of contamination and use of scarce resources. It will also help make seed readily available for distribution to national partners and seed companies to reach the farmers much faster.

Kireger conveyed his appreciation for the cold room and other research facilities established on KALRO sites, terming these achievements as “rewarding not just to KALRO and to the seed companies, but to many smallholders in Africa, who continue to be the inspiration behind every effort put into maize research and development work by KALRO and partners like CIMMYT.”

In addition to the seed storage cold room, Africa hosts the maize lethal necrosis (MLN) disease screening facility in sub-Saharan Africa. The MLN screening facility was established in 2013 at KALRO Naivasha Center in Kenya in response to the outbreak of the devastating MLN disease in eastern Africa. The facility since then has supported both the private and public institutions to screen maize germplasm for MLN under artificial inoculation and in identifying MLN tolerant/resistant lines and hybrids.

“The MLN screening facility (also a quarantine site) has been supporting the national partners in sub-Saharan Africa, key multinational, local and regional seed companies and CGIAR centers. This facility has become a major resource in the fight against MLN regionally,” added B.M. Prasanna, Director of CIMMYT’s Global Maize Program as well as the CGIAR Research Program MAIZE. “Tremendous progress has been made through this facility in the last three years. Several promising maize lines with tolerance and resistance to MLN have been identified, and used in breeding programs to develop improved maize hybrids. Already five MLN-tolerant hybrids have been released and now being scaled-up by seed companies for reaching the MLN-affected farmers in Kenya, Uganda and Tanzania. As many as 22 MLN-tolerant and resistant hybrids are presently undergoing national performance trials in east Africa,” remarked Prasanna.

Another major focus of CIMMYT and partners in the region is to prevent the spread of MLN from the endemic to non-endemic countries in Africa. “This is a strong message to convey that we not only work hard to develop MLN resistant maize varieties for the farmers, but we are also very keen to control the spread of the disease” remarked Kropff during a visit to the site.

In Zimbabwe, an MLN quarantine facility has been established in 2016, in collaboration with the government. This facility is key for safe transfer of research materials, including those with MLN resistance into the currently MLN non-endemic countries in southern Africa, before they get to the partners.

In order to keep up with the emerging stresses and to accelerate development of improved maize varieties, the maize Doubled-Haploid (DH) facility was established in 2013 by CIMMYT and KALRO at the KALRO research center in Kiboko. This facility helps the breeders to significantly shorten the process of developing maize parental lines from 7–8 seasons (using conventional breeding) to just 2–3 seasons.

“Through the facility at Kiboko, we have been able to develop over 60,000 DH lines in 2015 from diverse genetic backgrounds. The DH facility also supports the national agricultural research organisations and small and medium enterprise partners in sub-Saharan Africa to fast-track their breeding work through DH lines,” said Prasanna.

For wheat research-for-development work in Africa, the largest stem rust phenotyping platform in the world sits at KALRO research center in Njoro, Kenya. The facility screens at least 50,000 wheat accessions annually from 20-25 countries. Following the emergence of the Ug99 wheat rust disease pathogen strain in Uganda, the disease spread to 13 countries in Africa. Close to 65 wheat varieties that are resistant to Ug99 stem rust disease have been released globally as a result of the shuttle breeding that includes selection from the screening site at KALRO Njoro.

“CIMMYT’s yearly investment of USD 37 million in Africa through various projects has translated into a success story because of the strong collaboration with our partners across Africa,” said Stephen Mugo, CIMMYT’s Regional Representative for Africa. He further added that “research work in Africa is not yet done. No institution, including CIMMYT, cannot do this important work alone. We need to, and will, keep on working together with partners to improve the livelihoods of the African smallholders.”

Education, supportive policies key to making biotechnology work for Africa

Written by on June 27, 2016. Posted in News.

NAIROBI, Kenya – Increasing public understanding of genetically modified crops and creating supportive policies were key recommendations made at a session on boosting Africa’s use of biotechnology at the 7th Africa Agricultural Science Week.

With the population of sub-Saharan Africa projected to reach between 1.5 and 2 billion by 2050 and agriculture struggling to adapt to climate change, the pressure to meet the increasing demand for staple foods, including maize and wheat, has raised interest in biotechnology’s ability to boost yields.

Despite a recent U.S. National Academy of Science study concluding that genetically engineered crops are safe to grow and eat, and growing support for the use of genetically modified (GM) crops, there continues to be controversy around biotechnology.

The African Agricultural Technology Foundation (AATF) hosted a session on “Taking GM crops to market in sub-Saharan Africa: Special focus on policy and regulatory environment,” to discuss policy challenges to biotechnology in Africa.

Participants recommended raising public understanding of biotechnology through farmer and consumer education while enhancing functional policy and regulatory systems to facilitate testing and uptake of demand-driven GM products. The recommendations were to be presented to policymakers in the region.

At the session, Stephen Mugo, CIMMYT principal breeder and regional representative for Africa, spoke on biotechnology’s ability to improve conventional breeding.

“Genetic modification can be used in specific cases, for example, when a trait is very difficult to improve by conventional breeding methods or when it will take a very long time to introduce and/or improve such trait in the crop using conventional breeding methods,” said Mugo. “The use of biotechnology can maximize yield gains in ways that are compatible with human and environmental safety.” Hence, farmers should be given a chance to benefit from GM crops because they could increase their opportunities, productivity and efficiency.

Although GM crops have been grown across the globe for the last 20 years, only three African countries — Burkina Faso, South Africa and Sudan — currently grow them. This is largely due to the controversy and ambivalence surrounding biotechnology policies, with most countries taking a precautionary approach towards adopting biotechnology.

As Francis Nang’ayo, AATF head of Regulatory Affairs said, “Most African countries have taken a precautionary policy position on GM technology borrowed largely from the Cartagena Protocol on Biosafety, which many countries signed, and which was primarily adopted to ensure environmental conservation.”

This, alongside other factors, such as their commitment to abide by other international conventions and the debate on GM technology, are keeping most African countries from adopting policies that support biotechnology. Nang’ayo added that most countries have adopted stringent regulatory frameworks governing different GM processes and that this apparent overregulation has inhibited advancement of GM technology into the hands of farmers.

However, there has been notable progress in countries such as Kenya, which recently approved the environmental release of genetically transformed maize that carries genes from Bacillus thuringiensis (Bt) following an application submitted to the National Biosafety Authority by AATF and the Kenya Agricultural Livestock and Research Organization under the Water Efficient Maize for Africa project. This is expected to serve as a litmus test for many African countries that are already conducting confined field trials of GM crops.

Still, most African smallholder farmers have no knowledge of or access to biotechnology. According to Gilbert Bor, a farmer from Kapseret in northwest Kenya, “Many farmers know and understand that seeds in our fields are from science and research, so new and innovative technologies including biotechnology need to trickle down to farmers once proven safe. If such a technology promises farmers improved productivity, income and livelihood, and the likelihood of reducing use of pesticide and insecticide, then it’s important that farmers and consumers are educated and informed.”

Building a sustainable future: A history of conservation agriculture in southern Africa

Written by on June 23, 2016. Posted in News.

This story is one of a series of features written during CIMMYT’s 50th anniversary year to highlight significant advancements in maize and wheat research between 1966 and 2016.

HARARE, Zimbabwe (CIMMYT) — When practiced unsustainably, agriculture has led to environmental degradation and famine, which have plagued civilizations through the centuries. Innovations such as irrigation or the plow (since circa 6,000 and 3,000 BC) increased productivity, but often deteriorated long-term soil fertility through erosion and other forms of degradation.

We are now facing historically unprecedented challenges to food security. We must increase food production by 70 percent to feed nine billion people by 2050, without damaging our finite and often already degraded natural resource base. In addition, farmers face more frequent drought and water scarcity, which makes it increasingly difficult to grow crops, and extreme weather events such as the 2015-2016 El Niño, which has already caused large-scale crop failures and soaring maize prices in southern Africa.

Conservation agriculture (CA) practices based on the principles of minimal soil disturbance, permanent soil cover and crop rotation are helping farmers combat growing environmental challenges by maintaining and boosting yields, while protecting the environment and increasing profits for smallholders globally. When CA practices are coupled with water-use efficient and drought tolerant varieties, the benefits are even greater.

Drought is increasingly common in Malawi, leaving an estimated three million people in need of urgent humanitarian food assistance this year alone. However, a fortunate few will escape hunger, including more than 400 farmers and their families in Balaka, southern Malawi, who have been practicing CA over the last 12 years. "Few farmers have livestock in Balaka, so crop residues can be kept on the fields instead of feeding them to cattle," according to Thierfelder, who says Malawi presents a good case for conservation agriculture. CIMMYT and its strategic development partner Total LandCare have helped more than 65,000 farmers adopt CA systems throughout the entire country.

“CA approaches can mean the difference between farmers being able to feed their families or having to starve,” says Christian Thierfelder, senior cropping systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT), regarding the recent El Niño – the strongest on record – in southern Africa. To date, approximately 10 million people in southern Africa are dependent on food aid and an estimated 50 million people are projected to be affected, pushing them to the brink of starvation.

Sustainable intensification of agricultural systems and practices such as CA have become a necessity for farmers in Africa, where a combination of climate change and unsustainable agricultural practices are undermining land and water resources. This, coupled with an exploding population, makes increasing productivity while conserving the environment absolutely urgent.

Based on its experience in Latin America, which began in the early 1990s, CIMMYT started its first CA project in Africa in 2004, targeting Malawi, Mozambique, Tanzania, Zambia and Zimbabwe. This initial work focused on understanding CA systems in the context of farmers and their environmental conditions and was funded by the German government and the International Fund for Agriculture Development. Its aim was to facilitate the adoption of CA systems by smallholder farmers. This culminated in the establishment in 2009 of a large PAN-African project on Sustainable Intensification of Maize-Legume Systems in Eastern and Southern Africa (SIMLESA).

Since then, CIMMYT has leveraged its large network of partners to scale out CA. Between 2010 and 2015, CIMMYT, supported by a large group of donors including the Australian Centre for International Agricultural Research, the International Fund for Agricultural Development, the United States Agency for International Development and the Food and Agriculture Organization of the United Nations, helped over 173,000 farming households in the region adopt sustainable intensification practices.

Today, CA research at CIMMYT in Africa is increasingly focused on adaptation to the changing climate, which is leading to more erratic rainfall, increased heat stress and seasonal dry spells, in an effort to increase the use of climate-resilient cropping systems. CIMMYT’s work on CA in the region has shown that the practice can significantly increase farmers’ resilience to climate variability and change. Combining sustainable intensification practices with improved varieties has proved to increase productivity by 30-60 percent and income by 40-100 percent under drought conditions.

Despite CA’s successes, many smallholder farmers in developing countries still lack knowledge and understanding of sustainable agricultural practices and often revert to traditional farming practices that are labor-intensive and environmentally damaging. Also, CA systems are difficult to scale out if favorable policies and markets are not in place.

Araujo Njambo (right), a smallholder maize farmer in Mozambique, was used to the traditional way of farming that his family has practiced for generations, which required clearing a plot of land and burning all plant residues remaining on the soil to get a clean seedbed. However, as demand for land increases, this fuels deforestation and depletes soil nutrients. CIMMYT has been working with farmers like Njambo since 2006 to adapt sustainable intensification practices like CA to his circumstances. In remote areas of Mozambique, where Njambo’s farm is located, CA systems provide significant benefits during dry spells because farmers have no access to irrigation and depend only on rainfall. In the 2013-2014 cropping season, Njambo harvested his best maize yield in the last six years thanks to CA.

Mineral fertilizer, for example, is a basic agricultural input, but its adoption and use remain limited in sub-Saharan Africa. Farmers apply less than 10 kilograms per hectare on average due mainly to poor distribution networks (especially in rural areas) and high prices that are 3-5 times those in Europe. Lack of knowledge and training on how to use mineral fertilizer and other agricultural inputs renders them ineffective.

New discoveries in agriculture and breeding must be adaptable and transferable to smallholder farmers. This means improving physical distribution of technologies, training, knowledge and information sharing, credit availability and creating enabling environments for growth.

Just before passing away in September 2009, world-renowned agricultural scientist Norman Borlaug famously implored the world to “take it to the farmer” – a call to action we must follow if we are to sustainably feed the world by 2050. Without a basic understanding of good agricultural practices, most smallholder farmers will not be able to grow enough crops to move past subsistence farming.

Seeding the future: Emergency support for drought-affected farmers in Ethiopia

As the Rio 2016 Olympics draw near, team managers are rushing to recruit their best sportspeople from all over the country, put them through fitness tests, and get them to various stadiums before the starter’s gun goes off.

The team working on the Emergency Seed Support for Drought Affected Maize and Wheat Growing Areas of Ethiopia initiative is facing a similar challenge. But instead of recruiting long jumpers and marathon runners, they are tasked with procuring quality seeds of elite maize, wheat, and sorghum varieties and distributing them to farmers before the start of the main planting season to increase food security in regions devastated by recent droughts.

Dry conditions are not uncommon in Ethiopia, but the 2015-2016 El Niño – the strongest on record – has led to the worst drought in a decade. Harvests across Ethiopia were affected, leaving 10.2 million people – more than 1 in 10 Ethiopians – in need of emergency food assistance.

Planning for a food-secure future

The government of Ethiopia and international organizations are working to provide food aid for people facing immediate shortages, but Bekele Abeyo, senior wheat breeder and pathologist at the International Maize and Wheat Improvement Center (CIMMYT) for sub-Saharan Africa and leader of the emergency seed project, is focusing on a more sustainable future.

“Relief efforts will provide sustenance today, but we need to ensure there is also food on plates tomorrow,” says Abeyo. “With the large crop losses experienced in 2015, farmers were not able to save seed for planting in 2016 and did not have sufficient income to purchase more. Unless these farmers are able to access seed, we may face further shortages in 2017.”

CIMMYT, with support from the U.S. Agency for International Development, is working with partners to supply over 2,700 tons of seed to more than 226,000 households across 71 woredas (districts) in four regions of Ethiopia. CIMMYT will work with both the formal seed sector and farmers’ cooperatives to source quality seed from within Ethiopia and make sure it reaches the farmers who need it the most. These high-yielding, drought resistant varieties are being supplied along with agronomic advice to further increase farmers’ resilience.

Together with Ethiopia’s Agricultural Transformation Agency (ATA), a primary partner in the project, CIMMYT organized workshops in each of the target regions –Amara, Oromia, Southern Nations, Nationalities, and People’s Region (SNNPR), and Tigray – to engage stakeholders and collectively finalize the workplan. Based on participant feedback, some sorghum will now also be supplied to selected regions, in addition to maize and wheat.

“It is important to consider the needs of the individual communities and regions,” says Yitbarek Semeane, director of ATA’s Seed Systems. “ATA has very strong links with the regions and government institutions so is able to provide feedback on farmers’ needs and preferences. As weather patterns in Ethiopia are becoming increasingly unpredictable, many farmers are changing their farming practices, or even switching crops.”

A race against time

With the main planting season rapidly approaching, the team is racing to source, procure, certify, transport and distribute seeds.

“The success of this project will depend on us procuring enough quality seed and distributing it to farmers before the main planting season,” says Tadele Asfaw, CIMMYT-Ethiopia program management officer and member of the project’s Seed Procurement Committee.

By mid-April, the team had successfully procured almost all the required maize and sorghum seeds and were navigating the complex logistics to get the requested varieties to each woreda. Agreements are also being signed with farmers’ cooperatives to ensure that wheat seed can be purchased without disrupting the normal seed system.

According to Ayele Badebo, CIMMYT scientist and wheat seed coordinator for the project, CIMMYT does not have the capacity to collect seed from individual farmers within each woreda, but this is something the cooperatives are ideally placed to do. They have the trust of both CIMMYT and farmers, and through the previous seed scaling project, they know which farmers were given seed to multiply and will now have it available for sale.

At the end of March, the seed procurement team traveled to eastern Oromia – one of the areas most affected by the 2015 drought – to meet with Chercher oda bultum, a farmers’ cooperative and seed supplier. The team was very satisfied to see that the supplier had sufficient stock of Melkassa2 and Melkassa4, locally-adapted drought resistant maize varieties that had already been certified for germination and moisture by another collaborator, Haramaya University. This same process is now underway for wheat seed.

Ethiopia’s Bureaus of Agriculture and Natural Resources are also working with woreda representatives to ensure that the seed will be distributed to those farmers who need it most, and who have sufficient land and agronomic tools to benefit from this initiative.

“Working with local enterprises and partners enables us to procure and deliver seed to drought-affected farmers as quickly as possible,” says Abeyo. “In combination with CIMMYT’s longer-term efforts in the region, we hope that we can foster a more robust seed system and increase food security for 2016 and beyond.”

Partnering for success

While CIMMYT has the knowledge, networks and experience in Ethiopia to spring into action, the cooperation of partners such as the Agricultural Transformation Agency (ATA), farmers’ unions and Ethiopia’s Bureaus of Agriculture and Natural Resources is vital.

Established in 2010, the ATA is acting as a catalyst to spur the growth and transformation of Ethiopia’s agriculture sector. With funding from the Bill & Melinda Gates Foundation, ATA is working with the Ministry and Regional Bureaus of Agriculture and Natural Resources to coordinate the collection, cleaning, packing, labeling and distribution of quality seed to drought-affected farmers, as well as help train development agents and raise farmer awareness.

New Publications: Advances in breeding for future climates

CIMMYT scientists have made progress in breeding for early-maturing and heat-tolerant wheat lines in South Asia according to a recently published study. Maintaining wheat productivity under increasing temperatures and decreasing water availability in South Asia is a challenge. Warmer temperatures have already been determined to be one of the major factors in slowing the wheat productivity growth in South Asia, with estimated grain yield losses at 6 to 10% per ◦C rise in temperature.

In response, CIMMYT researchers focused on developing early maturing wheat lines as an adaptive mechanism in regions suffering from terminal heat stress and those areas that require wheat adapted to shorter cycles under continual high temperature stress. Each year from 2009 to 2014, 28 newly developed early-maturing high-yielding CIMMYT wheat lines were evaluated across locations in South Asia. A positive trend was observed while estimating the breeding progress across five years for high-yielding early-maturing heat tolerant wheat compared to the local checks in South Asia, suggesting early maturity has the potential to improve adaptation and maintenance of genetic gains in South Asia. Read the full study “Grain yield, adaptation and progress in breeding for early-maturing and heat-tolerant wheat lines in South Asia” here.

Another recently released study on physiological breeding reveal opportunities for more precise breeding strategies and feed models of genotype-by-environment interaction to help build new plant types and experimental environments for future climates. Physiological breeding crosses parents with different complex but complementary traits to achieve cumulative gene action for yield, while selecting progeny using remote sensing, possibly in combination with genomic selection. Among other findings, the study concludes that new crop designs capitalize on over half a century of physiological research, remote sensing allows evaluation of genetic resources for complex trait expression, and genetic and physiological dissection of complex traits enables better crosses.

DHARWAD, INDIA — Nearly 150 scientists, researchers and extension agents from universities and agricultural departments across the state of Karnataka, India, attended a field training 12-13 April on conservation agriculture and farm mechanization for sustainable intensification. The training was hosted by the University of Agricultural Sciences (UAS), Dharwad, Karnataka, and jointly organized by CIMMYT, UAS and Karnataka’s Department of Agriculture.

South Asia is one of the most vulnerable regions to climate change. Flooding and drought coupled with seasonal rainfall changes are predicted to devastate agriculture, with extreme heat already disrupting the growing season in India and other countries. Wheat production in India’s Indo-Gangetic Plains may decrease by up to 50 percent by 2100, harming the hundreds of millions who rely on the region for food security. India also extracts more groundwater than any other country in the world to support agriculture, with northern India’s groundwater declining one meter every three years.

Karnataka faces these and other challenges, including production system constraints, mono-cropping and lack of access to markets, storage facilities, processing units and real-time information. Other constraints include large post-harvest losses, labor and energy shortages, poor mechanization and fodder scarcity.

J.V. Goud, Ex Vice Chancellor, UAS, Dharwad, described these challenges in his inaugural address and emphasized the need for sustainable agriculture practices to achieve food security in India.

“Courses like this help combat climate anomalies and make agriculture practices drought-proof,” said Goud. Sustainable practices have proven successful in addressing water shortages in agriculture. For example, trainees were introduced to precision land leveling, which can raise India’s wheat yields more than 16% and increase water productivity by 130%.

According to M.L. Jat, CIMMYT senior cropping systems agronomist and an expert in conservation agriculture (CA), “Climate-smart agriculture practices such as CA not only minimize production costs and inputs, but also help farmers adapt to extreme weather events, reduce temporal variability in productivity, and mitigate greenhouse gas emissions, This is backed up by ample data on conservation agriculture management practices throughout the region.”

Conservation agriculture is sustainable and profitable agriculture based on minimal soil disturbance, permanent soil cover and crop rotations. It is improving farmers’ livelihoods throughout South Asia and has led to policy-level impacts through the implementation of CA practices covered in the training, such as precision land leveling, zero tillage, direct seeding and crop residue management.

Trainees were taught how to operate a variety of CA machines, including multi-crop zero-tillage machines that can calibrate the amount of seed and fertilizer and control speed for seeding different crops. They also learned about other practices such as weed, nutrient and water management using precision support and sensors.

Scientists and researchers who imparted the training included Jat, CIMMYT agronomist H.S. Jat, CIMMYT hub manager S.G. Patil, CIMMYT consultant Yogesh Kumar Singh, Borlaug Institute for South Asia (BISA) senior research engineer H.S. Sidhu, BISA senior scientist R.K. Jat and Deputy Director of the International Plant Nutrition Institute’s India Program-South Zone, T. Satyanarayana.

Genetically engineered crops safe to grow and eat, U.S. National Academy of Sciences concludes

Written by on June 1, 2016. Posted in Features.

EL BATAN, MEXICO (CIMMYT) — Genetically engineered (GE) crops are as safe to eat as conventionally bred crops and have benefited the environment and ecosystem diversity by reducing pesticide use, according to a study released by the U.S. National Academy of Sciences (NAS) earlier this month.

Conducted by a committee of 20 scientists chosen by the NAS to represent diverse disciplines relevant to the topic, the study brought together ample and broad-ranging evidence from the last 20 years, the period since the first commercial release of GE crops, regarding their impacts on yields, the abundance and diversity of insects, insecticide and herbicide use, the development of resistance to agrochemicals in weeds and pests, human and animal health and various other aspects of concern to society.

The committee collectively read 900 studies and publications, listened to 80 speakers at public meetings and webinars and reviewed over 700 comments and documents submitted by the public on GE crops past, present and future.

“Consumers and stakeholders have made diverse claims about GE crops, ranging from ‘they cause cancer’ to ‘we cannot feed the world without them,’” said Kevin Pixley, director of the Genetic Resources Program at the International Maize and Wheat Improvement Center (CIMMYT) and member of the committee authoring the report. “The report is both retrospective and forward-looking; it openly considers all credible views and evidence, and provides findings and recommendations on a wide range of issues pertinent to GE and future novel crops.”

Regarding health concerns, the committee found no conclusive evidence that GE crops have contributed to obesity, diabetes, kidney disease, autism, celiac disease or food allergies. The report also states that there is “no conclusive evidence of cause-and-effect relationships between GE crops and environmental problems.”

The committee raised a red flag regarding weed and insect species developing resistance to commonly used herbicides and pesticides where farmers had grown GE crops without following proper practices to avoid this development. The authors noted that these issues are not unique to GE crops and said they deserved special attention and research.

“The report contains a wealth of information about GE crops that enables readers to delve into the issues and topics of greatest interest or concern,” said Pixley. “Sweeping conclusions about GE crops are few, because the issues are multidimensional and often viewed differently by each individual.”

For the last 20 years some publics have waged a war on GE crops and urged they be banned from production. As one result, virtually no GE crops have been grown in most of Europe and calls for stricter labeling on GE products have also been made in countries including the United States and Canada.

The report states that regulators should not focus on genetic engineering or the process by which new crops are bred, but rather perform safety testing on individual products, based on their novelty and potential for adverse health or environmental effects.

Along the same lines, the study observed that a variety of new technologies, including gene-editing techniques, such as CRISPR/Cas9, which allow researchers quickly and efficiently to edit, cut out, and replace genes, are blurring the distinction between genetic engineering and conventional plant breeding.

“This is similar to the blurring of the differences between what we have been able do with our cell phones and computers over the last 20 years,” explained Pixley.

Included in the report is a list of traits, including those which can enhance nutritional value, food safety, forage quality and post-harvest storage, that are being or will likely be bred into future varieties using an expanding toolbox that includes genetic engineering, gene editing, genomic selection and others.

“This report provides a fresh perspective and proposes a conceptual framework for managing potential health or environmental risks of novel crop traits, regardless of which process or technology is used to breed them into our crops,” said Pixley “Genetic engineering and other emerging technologies offer options for plant breeders to meet the crop production and food security challenges of this and future generations.”

CHENGDU, CHINA – The International Maize and Wheat Improvement Center (CIMMYT), in collaboration with the Sichuan Academy of Agricultural Science (SAAS) is expanding conservation agriculture (CA) practices to promote sustainable intensification (SI) (i.e., agriculture aimed at enhancing the productivity of labor, land and capital) in China’s Sichuan Province.

Sustainable intensification can simultaneously address a number of pressing development objectives, including adapting production systems to climate change, sustainably managing land, soil, nutrient and water resources, improving food and nutrition security and ultimately reducing rural poverty. Zero tillage (ZT) minimizes soil disturbance, provides continual residue soil cover and includes crop rotations, all of which increases soil fertility and water use efficiency and helps cereal farmers sustain their crop yields over the long term.

As part of a joint CA project with CIMMYT, Tang Yonglu, Dean of the Crop Research Institute, SAAS, and his team have promoted sustainable mechanization and residue management, incorporated farmer input and hosted demonstrations in the rainfed regions of Sichuan. As a result, farmers from Mianyang District in Sichuan are now interested in ZT; a plan was thus put in place to build capacity and help farmers plant ZT maize and rice in May and June 2016.

Chaosu inspects an immature ZT wheat field affected by frost. This crop will be followed by ZT mechanically transplanted rice into the standing residue in late May. Previously, rice was manually transplanted by women following conventional inversion tillage. This new planting scheme tested by CIMMYT in north western China will save 1-2 weeks and considerable input costs for the new ZT farmers in south west China.

At an annual SAAS-CIMMYT meeting, Tang’s team presented their findings on the effect soil compaction and waterlogging have on wheat production. Soil compaction occurs when random wheeling over cropping areas of farm vehicles, such as tractors and harvesters, packs the soil so tightly that soil conditions deteriorate, reducing crop yields. Waterlogging caused by flooding or intense rain on degraded soils also negatively affects yields.

At the meeting, CIMMYT proposed managing soil compaction through controlled traffic farming (CTF), an essential ZT practice that alleviates soil degradation. CTF permanently separates the crop area and the traffic lanes, thereby avoiding vehicle-induced soil compaction and improving and sustaining soil health. SAAS plans on implementing CTF as one tool in its sustainable intensification efforts.

During the two-day event, local researchers presented their academic and work reports and attended a field demonstration on advances in ZT mechanization; technical training sessions for farmers were also held. Other researchers addressed subjects such as soil health, weed control, sustainable techniques for rainfed wheat and mechanization techniques for rainfed maize.

Field demonstrations compared the performance of crops sown using locally produced one-pass planting machines and the Chinese made Turbo Happy Seeder. It was the first time participating researchers and farmers had seen a demonstration of the Happy Seeder. The Chinese seeder minimizes soil disturbance and uses devices that block residue, which makes it very useful for planting irrigated and rainfed crops when high levels of residue are maintained in the fields. For the locally produced machines to operate successfully, they require low levels of residue on the soil surface or that residues be incorporated into the soil.

Differences in planting machinery performance were difficult to discern in the wheat fields, due to yield losses across the region as a result of a very cold period in January. What was apparent was that while all the machines were equally effective in terms of crop establishment, there appeared to be slight differences in water stress in crops sown by the rotary till planter (high soil disturbance) and the non-rotary planter (low soil disturbance). This improvement in crop soil water was not lost on the participants as they strolled through the fields while listening to Li Chaosu, senior researcher at the Crop Research Institute, SAAS, explain the results.

CIMMYT SAAS collaboration is set to expand in the mountainous regions of Sichuan Province later this year, when new farmers come on board to implement ZT rice transplanting. The Green Farming Association, in collaboration with the local Agricultural Mechanization Bureau based in Santai, is also forging ahead with its conservation agriculture plans with CIMMYT’s guidance and support.

Harnessing maize biodiversity for food security, improved livelihoods in Africa

Written by on May 20, 2016. Posted in Features.

HARARE (CIMMYT) — As CIMMYT joins the world in celebrating the International Day for Biological Diversity on 22 May, it can take pride in the diverse maize varieties it develops which have improved the livelihoods and health of smallholder farmers globally.

These varieties have brought tremendous benefits to smallholders in sub-Saharan Africa (SSA). Over 90 percent of agricultural production in SSA is rainfed, which puts farmers at risk for drought and heat in addition to the poor soil fertility, pests and diseases they face. Drought alone damages about 40 percent of all maize crops in SSA, endangering the livelihoods and food security of millions of smallholder farmers.

Stress tolerant maize not only reduces risks for farmers in the face of unpredictable environmental and biological conditions, it also allows more stable crop production. The International Maize and Wheat Improvement Center (CIMMYT) breeds high-yielding, locally-adapted maize varieties with farmer-preferred traits such as drought tolerance, nitrogen use efficiency, and disease and insect pest resistance. Many of these varieties also have increased nutritional traits such as high protein quality and increased provitamin A content, which help increase children’s weight and height growth rates and reduce childhood blindness.

“Since working with CIMMYT, we have unlocked our production potential, ‘’ said Sylvia Horemans, Marketing Director of Zambian-based Kamano Seeds. Since its establishment in 2012, Kamano Seeds has benefitted from CIMMYT to strengthen its work in maize breeding besides technical support on maize seed production and marketing.

“Increasing adoption of these stress tolerant maize varieties is helping African farmers cope with drought and climate change, improve yields at household level and thereby enhance the livelihoods and food security of tens of millions of farmers,” said Cosmos Magorokosho, CIMMYT-Southern Africa maize breeder.

These drought-tolerant varieties have proven resistant despite harsh conditions brought on in southern Africa by an intense El Niño, according to Magorokosho. “Significant impacts have been observed in plots of smallholder farmers who grow these varieties.”

In 2014, over 54,000 metric tons of certified seed of the stress tolerant maize varieties were produced and delivered by partner seed companies for planting by smallholders. By the end of that year, more than five million smallholders had planted the improved drought tolerant varieties on over two million hectares, benefiting more than 40 million people in 13 countries in SSA.

Today, there are more than 200 stress tolerant maize varieties that yield the same or more than commercial varieties under average rainfall, and more importantly, produce up to 30 percent more than commercial varieties under moderate drought conditions. Armed with these improved varieties, CIMMYT is assuming a greater role to ensure stress tolerant maize reaches nearly five and a half million smallholder households in SSA by the end of 2019.

“The rain is very little here, but even with a little rain, this seed does well,” says a smallholder farmer Philip Ngolania, in south-central Kenya, referring to a drought-tolerant maize variety he planted during the 2015 crop season. “Without this seed, I would have nothing. Nothing, like my neighbours who did not use the variety."

“In close collaboration with our partners, we were able to create excitement about what can be achieved with drought tolerant maize in Africa,” said Tsedeke Abate, leader of CIMMYT’s Stress Tolerant Maize for Africa project. CIMMYT is working with national agricultural research systems, international research centers, and other development programs to disseminate improved maize seed to smallholder farmers in SSA through small-and medium-sized seed companies.

“The work we have undertaken on drought tolerant maize has created significant impacts. However, several challenges still remain,” cautioned B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program MAIZE. One of these challenges is maize lethal necrosis (MLN), which emerged in Kenya in 2011 and has since devastated maize crops across East Africa. CIMMYT is working to generate improved stress tolerant maize varieties with resistance to MLN and other major diseases.

Maize production in Africa is growing rapidly, making maize the most widely cultivated crop on the continent, and the staple food of more than 300 million people. Providing farmers with diverse, improved seed choices will thus strengthen food security, health and livelihoods in SSA.

New Publications: Maize Lethal Necrosis survey reveals farmer impact, future needs

Written by on May 16, 2016. Posted in Publications.

NAIROBI, Kenya (CIMMYT) – When a strange maize disease suddenly appeared in 2011 in Bomet, a small town 230 kilometers (143 miles) west of Kenya’s capital city, Nairobi, scientists from CIMMYT and Kenya Agricultural Livestock and Research Organization were thrown into disarray. The disease, later identified as Maize Lethal Necrosis (MLN), became a nightmare for maize scientists leading many to work around the clock to find a solution to stop its rapid spread. As intensive research and screening work started, it became apparent that there was a dire need to fill a glaring information gap on the disease, particularly regarding MLN’s geographic distribution, the number of farmers affected, the levels of yield loss and the impact of those losses.

To address this gap, surveys were conducted with groups of male and female farmers in over 120 sub-locations of Kenya’s maize production zones in a recent study “Community-survey based assessment of the geographic distribution and impact of maize lethal necrosis (MLN) disease in Kenya.” The results estimate maize losses from MLN at half a million tons per year with the highest losses reported in western Kenya. The study identified an urgent need to develop improved maize varieties resistant to MLN and emphasized the need for farmers to be informed and adapt appropriate agronomic practices to cope with the disease.

NEW DELHI (CIMMYT) — Rice-wheat rotation is practiced by farmers on over 13 million hectares of farmland in South Asia, providing the primary source of food security in the region. However, climate change is projected to have a huge impact and reduce agricultural production 10 to 50 percent by 2050. Complex and local impacts from climate change and other challenges require solutions to risks that can be readily-adapted. Representatives from Bayer Crop Science recently visited the International Maize and Wheat Improvement Center (CIMMYT) offices in India to discuss the potential for developing jointly managed sustainable approaches and technologies to address such challenges.

Sustainable intensification, which involves such conservation agriculture practices as minimal soil disturbance, permanent soil cover and the use of crop rotation to increase profits, protect the environment, maintain and boost yields, is a potential solution that has worked to address the impact of climate change in South Asia. Such practices contribute to improved soil function and quality, which can improve resilience to climate variability.

“Systems research with conservation agriculture practices like direct seeded rice, no-till wheat and recycling crop residues have shown tremendous potential to address the challenges of water and labor scarcity, conserve natural resources and lower the environmental footprint of South Asia’s food bowl,” said M.L. Jat, CIMMYT senior cropping systems agronomist and the South Asia coordinator for the CGIAR Research Program on Climate Change, Agriculture and Food Security, collaboratively managed by the CGIAR consortium of international agricultural researchers.

During the Bayer meeting, challenges and opportunities were identified for direct seeded rice — which requires less labor and tends to mature faster than transplanted crops — and sustainable intensification programs throughout South Asia, particularly in India. Discussions were based on the success of other CIMMYT-Bayer collaborations across South Asia that aim to address agricultural challenges through sustainable intensification — including direct seeded rice — quantifying mitigation potential of conservation agriculture-based management in rice-wheat rotation and smart farm mechanization to make farm management more efficient and productive.

Moving forward, CIMMYT and Bayer will focus on agricultural systems research to ensure even more effective interventions with higher yields, collaborate to develop new sustainable technology and increase uptake throughout the region. Sustainable intensification practices are expected to continue to grow in the region thanks to these and other collaborations, along with the advent of technological advancements and increased adoption.

As PARC Chairman Nadeem Amjad indicated, today the use of ICT is essential and AIP’s efforts will make it easy to convey relevant and credible information to extension staff and, through them, to farmers.

The United States is committed to working hand in hand with Pakistan to develop and modernize the agricultural sector. As a global center of excellence in the improvement of maize and wheat systems, CIMMYT has maintained a long and highly productive relationship with the Pakistani government and national partners, with the invaluable support of U.S. government agencies. AIP’s E-Pak Ag activities are capturing science and research innovations led by UC Davis, which has a rich history of working with and strengthening research, education and extension programs around the world.

Launched in 2013, the USAID-funded Agricultural Innovation Program for Pakistan (AIP) works to increase agricultural productivity and incomes by promoting and disseminating modern practices in the cereal and cereal systems (wheat, maize and rice), livestock, fruit, and vegetable sectors; enhancing the capacity of agricultural scientists and researchers through short-term and long-term training such as M.Sc. and Ph.D. scholarships at U.S. land grant universities; establishing Provincial Agricultural Research for Development (AR4D) Boards to support expansion of provincial linkages to national, regional and international communities through a mechanism of coordination; and improving agricultural growth and research in Pakistan through a Competitive Grants System. Project management is vested in a unique consortium of Consultative Group for International Agricultural Research (CGIAR) centers, US land grant universities, non-CGIAR centers, and the Pakistan Agricultural Research Council (PARC), led by the International Maize and Wheat Improvement Center (CIMMYT).

PALMIRA, COLOMBIA — A field day was organized at the International Center for Tropical Agriculture (CIAT) to show the advances of CIMMYT’s HarvestPlus project in Colombia and throughout Latin America. 58 participants representing regional agriculture, education and health sectors, Colombian agricultural institutions, seed producing companies and producers’ guilds, non-governmental organizations and food processing and supply companies. CIAT and CIMMYT staff involved in HarvestPlus also attended the event.

Conferences held during the field day aimed to show participants the benefits of a biofortification program. Meike Anderson, a HarvestPlus crop development specialist of presented strategic priorities for developing and commercializing biofortified crops, emphasizing more than 2 billion people worldwide suffer from hidden hunger, or micronutrient deficiencies.

HarvestPlus was created to combat hidden hunger, and operates in over 40 countries with more than 200 partners. The project began in 2004 and is now in the dissemination phase. HarvestPlus is directly in line with the CGIAR’s goal to ensure improved crop varieties are designed to have high in nutritional value. HarvestPlus in turn has prioritized the development of maize seed with high zinc and provitamin A content. In Colombia 20% of the population is zinc deficient as it much of the population in other Latin American countries including Guatemala, Nicaragua, Brazil, Mexico and Peru.

Maize is the staple food of around a third of malnourished children all over the world. In Colombia 25% of children under 5 years of age present vitamin A deficiency. Biofortified food could have a huge impact improving diet in Colombia and across the globe.

CIMMYT aims to include higher protein quality, lysine, zinc and provitamin A in biofortified maize. To date, there are at least 10 biofortified varieties than after released that can be sown by farmers for both urban and rural consumers, all which were on display during the field day. A farm-to-plate strategy including beans, rice, cassava and yams should also be implemented.

Carolina Gonzalez, HarvestPlus economist, also presented socioeconomic studies prioritizing biofortification in Colombia during the event, identifying areas on the Atlantic coast as the greatest in need due to high levels of vitamin A and zinc deficiency. Sonia Gallego, post harvest Research Assistant of HarvestPlus, provided information from retention and nutrition studies on biofortified maize, emphasizing how important maize grain processing and conservation from harvest to food production are for vitamin A and zinc availability in the human body.

Field activities were also presented by CIMMYT researchers Felix San Vicente and Luis Narro. They emphasized the importance of delivering to farmers biofortified maize seeds that still produce yields that can compete with their competitors. During an event hosted earlier in the year evaluating biofortified hybrids, the grain yield of the best hybrid was nearly ten tons per hectare, which is on par with the best performing maize used as a control group. This proves that high zinc or protein content does not cause farmers a loss in yield – just gains in nutritional. Biofortification also proved to have no effect on other traits like disease resistance, grain type or plant architecture.

At the end of the field day, teams identified institutions and companies that will take charge of varietal release and the seed production process in Colombia, including CORPOICA, Fenalce, Semivalle and Semillas Guerrero. In addition, CIMMYT will simultaneously sow plots to demonstrate to seed companies and other institutions the agronomic traits of different varieties.

Government programs that provide food for school children were also identified as potential collaborators to meet high demand for maize and malnourished children in that state of Valle del Cauca. Colombia demands is 1,200,000 tons of maize for food uses annually, with many producers and processing companies interested in the benefits of using biofortified maize and other crops.

Everyone who attended the workshop evaluated plant and grain traits and compared experimental plot yields. As a result, the seed companies decided to organize agronomic evaluation plots starting in 2016 and establish semi-commercial plots of hybrids, with the goal to release the first biofortified maize in 2017.

Among workshop attendees were CORPOICA and ICA, seed companies Semivalle, Maxisemillas, Semillas del pacífico and Procampo, producers guilds FENALCE, FEDERECAFE and ARDECAN, non-governmantal organizations including CETEC, FIDAR and CLAYUCA and companies Fundación Naturaleza y Vida and Pampa also attended.

“Farmers recommend,” a participative proposal by MasAgro Guanajuato

Irapuato, Guanajuato, 22 March, 2016.- MasAgro Guanajuato and the International Maize and Wheat Improvement Center (CIMMYT), through the “Farmers Recommend” campaign spanning from January till mid March, shared Guanajuatan farmers’ experiences with sustainable agriculture to scale out good agronomic practices and encourage more farmers to join the initiative.

Work methodologies that promote the development, adaptation, transfer and adoption of sustainable agricultural technologies and practices were shared through social networks and communication channels, which farmers also used to voice their opinions. During the campaign, 7 articles were published in the EnlACe Bulletin, 15 on Facebook that reached 29,067 people, and 40 tweets that were received by 47,821 people. MasAgro Móvil was another way we disseminated information about the campaign, with 7 messages reaching 1,300 people each week.

Marcelino Vázquez, representative of the organization Agro Productores Dobladenses, shared the marketing experiences they had during the 2014-2015 fall-winter cycle. He explained that farmers established the organization in order to improve their production systems and livelihoods, and recognized that working in coordination with SDAyR and MasAgro Guanajuato had been important to the success of the organization.

As a result of their efforts, from 2014 to date, farmers were able to market around 8,000 tons to different companies (Pepsico and flour processors). Despite not having a commercial infrastructure, these types of actions have improved the organization’s production and marketing systems; for this reason, Agro Productores Dobladenses recommends contract agriculture, which is a marketing alternative that allows farmers to get a good price for their harvest. It also ensures they will be able to market a certain volume at a specific price.

As for fertilization, farmers Fernando Castro García and Jesús Morales shared their experiences using soil amendments on sorghum; they used solid fertilizer instead of ammonia. Guanajuatan farmers also shared their experiences in other areas such as machinery, crop rotations and pest management. They also came to a consensus about which cropping practices are most sustainable and profitable.

An outstanding feature of the campaign was that what we shared was the result of discussions held with farmers and other actors (such as technicians, researchers, the industry and institutions), in which a consensus was reached about which practices are best for optimizing productivity, profitability and environmentally friendliness. This allowed us to generate and disseminate local knowledge to modify the dynamics of decision-making and knowledge transfer.

See the messages that we shared during the campaign! Look for the hashtag #LosProductoresRecomiendan on Facebook and Twitter. And don’t forget to call 01 (462) 6226116 if you wish to take part in the MasAgro Guanajuato initiative or send an email to r.barrera@cgiar.org with “Participación en MasAgro Guanajuato” as the subject.

New Publications: Red root marker improves double haploid maize breeding

CIMMYT/MAIZE CRP handout

EL BATAN, Mexico (CIMMYT) — Doubled haploid (DH) technology provides important benefits to maize breeding programs by enhancing genetic gains, improving breeding efficiency and offering significant economic advantages.

Unfortunately, this technology is limited by the fact that the R1-nj (Navajo) anthocyanin color marker cannot effectively identify haploids in many crosses where inhibitor genes prevent color expression in the seed. A new study from the MAIZE CGIAR Research Program titled “Development and validation of red root marker-based haploid inducers that effectively complement R1-nj (Navajo) marker-based in vivo haploid identification in maize” states that the Navajo marker caused a high percentage of false positives, especially in varieties with natural purple coloring, due to high anthocyanin content.

To combat this issue, the study recommends the use of triple anthocyanin color markers, in which the red/purple coloration is expressed in seedling roots and leaf sheaths in addition to the Navajo marker on the seed. Researchers found that use of the red root marker improved the accurate identification of haploids, especially in seeds that already have a natural purple color due to high anthocyanin content.
