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

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. Photo: Christian Thierfelder/CIMMYT

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.

CIMMYT’s knowledge sharing efforts contribute to improved seed production in Africa

NAIROBI, Kenya (CIMMYT) – A staggering 80% of the 67 million inhabitants of central Africa’s Democratic Republic of Congo (DRC) rely on maize for food, despite the country’s underdeveloped national maize breeding and seed production program. The ravages of war may have limited development efforts, but renewed interest in the DRC by regional and global development partners will provide much needed infrastructure and knowledge sharing support.

Even with abundant resources such as water, labor and fertile land, availability of and access to quality seed remains a major hindrance to a thriving agricultural sector in the DRC. According to the state-run agricultural organization, Institut National pour l’Etude et la Recherche Agronomiques (INERA), North and South Kivu provinces in particular still import food from neighboring Rwanda, Uganda and Tanzania, with maize taking up the lion’s share of purchases.

Strategic public-private sector partnerships in agricultural research and development, such as the one between INERA, the International Maize and Wheat Improvement Center (CIMMYT) office in Kenya, and the Alliance for Green Revolution in Africa (AGRA), are an invaluable investment towards growth and sustainability of maize production in the region. AGRA funds multiple agricultural research projects in the DRC, while CIMMYT is renowned for its excellence in maize research globally. It is against this backdrop that breeders, agronomists, technicians and students gathered at the drought-tolerant (DT) maize site in Kiboko, Kenya, for a ten-day training course dubbed ‘Pollinations, Nursery and Trials Management’. The training, held from June 13 – 23, 2016, and jointly supported by CIMMYT and AGRA, and hosted by CIMMYT, emphasized hand pollination in maize variety development and seed multiplication.

Remarks by Stephen Mugo, CIMMYT Regional Representative for Africa, and Maize Breeder, highlighted training as one of the ways CIMMYT supports capacity building and development in the region.

He said, “It is my hope that knowledge and skills imparted during this course will be shared with other professionals at INERA, to improve maize breeding and production capabilities in the DRC.”

The course, organized by CIMMYT Maize Breeder, Lewis Machida, featured a mix of detailed lectures and practical exercises, expertly delivered by various CIMMYT scientists. Presentations covered topics such as basic seed production (hybrids and open pollinated varieties) and maintenance, breeding methods, and maize pollinations including hand pollination.

Hand pollination

Pollination, the process responsible for reproduction and continuity of plant life, is also a breeder’s playground, enabling shuffling of genes, plant adaptation and evolution. In maize breeding, this means development of seeds with tolerance to stresses such as drought, heat, pests and diseases.

Hand pollination, the general term for human intervention in this delicate process, can be further classified into self pollination, and cross pollination. As the name suggests, hand pollination is done by hand, calling for extreme care to minimize contamination and damage of plants.

“Successful production and maintenance of varieties depends largely on hand pollination. Without this process, it would be difficult to produce genetically pure seeds,” says Mugo, adding, “For this reason, hand pollination is considered the core of variety development in maize breeding.”

For the practical sessions of the course, participants deftly carried out the steps in hand pollination, including shoot bagging, pollen collection & placement, and detasseling.

Elois Cinyabuguma, Manager of INERA’s Cereal Unit, shared that the training offered much needed technical skills to scale up seed production in his country, saying, “With CIMMYT germplasm, and sound technical knowledge on multiplication, storage and pest & disease management, DRC is well on its way to setting up a well-rounded maize development program.”

Beyond building the DRC’s capacity for maize breeding and production in general, lessons from the training will be implemented first in North and South Kivu provinces, in hopes of reducing or eliminating maize imports. The event was also a unique opportunity to enhance collaboration among INERA, CIMMYT and AGRA, in anticipation of future shared projects pertaining to maize research, production and distribution.

All participants were issued with a certificate on successful completion of the course.

Bhutan and Bangladesh join forces to combat threat of rust diseases

BHUTAN — Yellow and brown rusts are among the most common and damaging challenges to wheat production in Bhutan. Yellow or stripe rust (Puccinia striformis f. sp. tritici), a disease favored by cool weather conditions, is a major threat owing to the prevalence of cool winter conditions during the cropping season in most wheat growing regions. In Bhutan, yellow rust is the first disease to appear in the cropping season and, if left uncontrolled, has the potential to destroy the whole wheat crop. It has occurred every year in most wheat growing areas over the last two decades.

Brown or leaf rust (Puccinia triticina Eriks.), the second most important wheat disease in Bhutan, is also favored by climatic conditions, with severe infection on different advanced wheat lines being recorded over the last ten years. This is an indication that leaf rust could be just as threatening as yellow rust if susceptible cultivars are grown under favorable environmental conditions. Finally, if these rusts are not controlled, it is possible that Bhutan could become a primary source of inoculum, which would then be carried to its neighbors by the wind.

Bangladesh, Bhutan’s southern neighbor, does not have much of a history of rust diseases, but climate change could alter that. And while yellow rust doesn’t occur at all in Bangladesh and leaf rust appears only occasionally (albeit with high intensity), both have the potential to spread in the country.

The absence of high rust pressure in Bangladesh is a serious challenge when it comes to evaluating the rust resistance of wheat lines needed to prepare for uncertain future climates. In contrast, Bhutan is in a strategic position to conduct yellow and leaf rust epidemiological studies and is active in regional and global efforts aimed at studying and managing rust. Therefore, for the first time, Bhutan and Bangladesh are collaborating on evaluating Bangladeshi wheat lines for resistance to yellow and leaf rusts with support from CIMMYT.

During the 2015–2016 cropping season, Bangladesh sent 50 advanced wheat lines identified as having potential rust resistance to Bhutan for screening. The evaluation was done under natural conditions at the Renewable Natural Resources Research and Development Center (RNRRD) in Bajo, about 70 kilometers east of Thimphu, Bhutan’s capital. The results are promising, with 30 lines showing resistance to the rusts. The data were shared with Bangladeshi partners, who will use them to inform their breeding decisions.

Bhutan has been collaborating with CIMMYT’s Global Wheat Program since 2011 and has released three rust resistant varieties from CIMMYT in the past two years. Although there has been regional collaboration on wheat research in South Asia mainly through CIMMYT, testing wheat lines from Bangladesh for rust resistance in Bhutan is a first.

EL BATAN, Mexico (CIMMYT) – Breeding and seed systems must be adapted to survive projected climate change if major loss of maize yields is to be avoided, a new report shows.

Tools that forecast the response of crops to different weather and climate conditions, coupled with crop yield modeling have enabled agricultural scientists to predict and formulate plans for potential future climate change.

“Responding better to changes in climate by improving efficiency of the breeding cycle and reducing the amount of time it takes to get improved maize into the hands of farmers is key to ensuring a food secure future,” said International Maize and Wheat Improvement Center (CIMMYT) maize breeder and co-author of the study Biswanath Das.

Projections for Africa demonstrate climate-change related increases in temperature will negatively impact on-farm yields as heat and drought stress shorten crop production time, the length of time between maize planting and harvesting, Das said.

Shorter and hotter growing seasons are expected to become a reality over the next 15 years, which could mean that maize varieties currently being developed may struggle to adapt, particularly since current breeding and commercialization cycles to improve maize in Africa can take several decades.

The report published in Nature Climate Change, led by Andy Challinor from the University of Leeds in collaboration with the International Center for Tropical Agriculture (CIAT) and CIMMYT, calls for an acceleration of breeding, delivery and adoption processes. The authors suggest that all stages could be sped up using a variety of techniques, requiring elaborate planning and coordination involving numerous actors and interest groups.

“Current warming will reduce yields unless maize breeding and seed systems adapt immediately,” Das said. “Increased collaboration among different breeding institutes and public-private collaborations are needed so that we share information, technologies and germplasm to make the best germplasm and technology available to the widest number of scientists as possible.”

“Seed systems could be working with regulators to reduce the amount of time it takes for varieties to become available to farmers and developing new ways of producing seed more cheaply and efficiently while maintaining quality.”

Public seed systems should continue working closely with the private sector to encourage the latest genetic advances to become available to farmers in the shortest time possible, Das added.

CIMMYT has undertaken other work in this area. An intensive breeding effort through the Drought Tolerant Maize for Africa (DTMA) project developed a large phenotyping network and breeding pipeline to produce new maize varieties with heat and drought tolerance. In collaboration with over 100 national seed companies, the project supported the production of 54,000 tons of drought-tolerant maize in 2014 alone, benefiting an estimated 5.4 million households – or 43 million people – across 13 countries in Africa.

In 2015, a new project was started to expand the success of DTMA so that more smallholder farmers in Africa would have access to affordable improved maize varieties through a network of national seed companies.

Despite the considerable efforts being made to adapt maize farming to changing climates, Das warned that they must be sustained and encouraged on a larger scale in order for breeding programs to produce climate-ready maize varieties for the future.

This study was supported by the CGIAR Research Program on Climate Change (CCAFS) and the CGIAR Research Program on Maize (MAIZE CRP).

This research is carried out with support from CGIAR Fund DonorsCCAFS Donors, MAIZE CRP Donors and through bilateral funding agreements. Funding for this project came from: Australian Centre for International Agricultural Research;  Ireland Department of Foreign Affairs and Trade; Netherlands Ministry of Foreign Affairs; New Zealand Ministry of Foreign Affairs & Trade;  Swiss Agency for Development and Cooperation; Thailand; UK Department of International Development; The United States Agency for International Development and the European Union. The Program is carried out with technical support from The International Fund for Agricultural Development.

Launch of new geo-informatics tool

NEW DELHI — The International Maize and Wheat Improvement Center (CIMMYT) has launched the beta version of the Landscape-scale Crop Assessment Tool (LCAT), a geo-informatics technology that will help scientists to forecast crop yields and identify regions where conditions will support the adoption of specific technologies. Using geo-informatics, the Cereal Systems Initiative for South Asia (CSISA), for example, was able to identify districts in the state of Odisha most prone to flooding and categorize them as areas ill-suited for direct seeded rice. LCAT will provide a platform for extension professionals, policymakers and research scientists to leverage geo-informatics for better decision-making. The tool was developed for South Asia but can be used globally.

“In the eastern Indo-Gangetic Plains, we promote early sowing of wheat, which is one of the most important adaptations to climate change. But we haven’t been able to accurately monitor and measure where it is being implemented and when,” explained Andrew McDonald, CIMMYT principal scientist and CSISA project leader. “In our line of work, it is crucial to understand where you’re making progress. While the data exists, it is often not integrated at the spatial level.”

Considerable environmental and man-made landscape diversity exists across South Asia. LCAT will help to analyze these landscapes and characterize large areas of land based on remote sensing data. It will serve two main purposes – to facilitate technology targeting and provide information such as crop status, phenology and yield goals to support crop management decisions.

“The first version of the tool uses datasets from CSISA sites in Bangladesh and India to characterize the existing cropland. However, the algorithms on which it is based are generic and can hence be applied to describe any dominant agricultural landscape across the globe,” said Balwinder Singh, CIMMYT crop simulation modeler. “Within CSISA, the tool will be used for specific applications extending to crop yield forecasting and monitoring, learning and evaluation.”

However, critical knowledge gaps between landscape-scale processes and technology targeting remain a challenge. To ensure policymakers and scientists are able to effectively collaborate in using this tool, a team of scientists from Oak Ridge National Laboratories (ORNL) visited New Delhi in May to conduct a training session on LCAT for CSISA staff and government partners from India and Bangladesh. The training not only demonstrated the tool’s beta version but also created greater understanding of its practical applications.

“If you’re a user of data, you spend 60 percent of your time just assembling data before analyzing it. We want to reduce that to 5 percent,” said Suresh Vannan, director of the ORNL Distributed Active Archive Center for Biogeochemical Dynamics and CCSI data theme leader.

LCAT is being developed in collaboration with ORNL and the Group on Earth Observations Global Agricultural Monitoring (GEOGLAM) Initiative. It is funded by CIMMYT as part of a five-year agreement with ORNL signed in 2014.

ISLAMABAD — CIMMYT in collaboration with Pakistan’s National Agricultural Research Center conducted a training course on maize breeding program management and statistical data analysis from 23-27 May 2016 in Islamabad, Pakistan. The training was attended by nearly 40 participants nominated from agricultural universities, public and private institutions across the country. It was the first in its kind to address breeding program management and introduce current software to analyze various phenotypic and genotypic data. This hands-on training will help scientists select varieties suitable for use by Pakistani farmers based on multi-environment datasets.

“Today, crop improvement techniques are getting advanced in each passing day and countries that are investing in cutting-edge science and state-of-the-art technologies not only are self-sufficient, but are leading exporters of their surplus products,” said Chairman of Pakistan’s Agricultural Research Council, Nadeem Amjad.

Amjad emphasized the need to build the capacity of scientists dedicated to fields such as crop modeling, bioinformatics and advanced agricultural statistical software to modernize and enhance agricultural productivity in Pakistan. He thanked CIMMYT for addressing the need that can help maize and wheat researchers to grow in these fields and improve their work.

“Thanks to this training I have analyzed all my data in just two hours. Before this it would have taken me months as I was using less efficient, less user friendly and very old software. This is a real support from CIMMYT and my tasks are greatly simplified,” said Rashad Rashid, a representative from Rafhan Maize Products private company.

Together with CIMMYT Pakistan scientists, the training was conducted by Mateo Vargas Hernandez and Alvarado Beltran Gregorio, consultant and senior data analyst from CIMMYT’s Biometry and Statistical Unit respectively, who are part of the team that developed the software used during the training.

“Sharing statistical software and training of  researchers by the very people who were involved in developing the software makes this training unique,” according to  Muhammad Azeem Khan, Director General of National Agricultural Research Center, who closed the ceremony.

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.

ISLAMABAD — CIMMYT’s Agricultural Innovation Program (AIP) held its annual maize working group meeting on 10-11 May with over 20 representatives from public and private seed companies and higher learning institutions in attendance. The working group evaluated AIP partners’ progress in deploying CIMMYT-derived maize hybrids and varieties to farmers.

Maize productivity in Pakistan has increased almost 75 percent since the early 1990s thanks to the adoption and expansion of hybrid maize varieties. However, the seed that spurred this growth is largely imported at an annual cost of $50 million. Since AIP’s launch in 2013, however, more than 80 CIMMYT-derived maize hybrids and open-pollinated varieties have been adapted to Pakistan’s diverse ecologies. Currently, 21 public- and private-sector companies are testing and deploying these locally-adapted cultivars to smallholder farmers across the country.

In his opening statement, Pakistan Agricultural Research Council (PARC) Chairman Nadeem Amjad cited AIP as the best example of sustainable development projects and said that one of its invaluable contributions is “sharing of valuable parental lines and breeder seeds.” He added that CIMMYT hybrids can help “resource-poor maize farmers have affordable maize seeds at their doorstep.”

At the meeting, partners reported on their progress producing parental seed and described how they planned to deliver quality seeds to farmers. They also identified key challenges in Pakistan’s maize seed value chain and recommended potential solutions during the group discussion.

In his concluding remarks, Pakistan’s National Agricultural Research Center (NARC) Director General Muhammad Azeem Khan said that it was only thanks to AIP innovations and interventions that NARC was able to start producing seed of biofortified hybrid maize, a first in the history of Pakistan.

Certificates of appreciation were presented by AIP to NARC for jump-starting hybrid seed production in Pakistan and hosting various national maize events in 2015, as well as to Tara Crop Sciences (Pvt.) Ltd. for conducting the best maize trials evaluated by AIP maize partners during the 2015 traveling maize seminar.

Maize is the second most important food crop in Nepal, after rice. It contributes approximately 25 percent of Nepal’s food basket and occupies around 26 percent of the total cropped area. Maize productivity (2.3 tons per hectare) in Nepal is still quite low compared to the global average of 5.5 tons per hectare (t/ha).

Growing demand from Nepal’s poultry industry cannot be met by growing only open-pollinated varieties. Because of their high productivity, quality and profitability, higher-yielding hybrids have become increasingly popular among farmers. However, most maize hybrids are only approved for sale and cultivation in the central and eastern Terai, east of the Narayani River. To meet market demand, farmers in many areas, especially in western Nepal, sometimes purchase non-approved hybrid seeds. These hybrid seeds are not registered at Nepal’s Seed Quality Control Centre and are traded through informal channels.

Not wishing to risk a government penalty for violating the seed policy, traders have not distributed many high-performing hybrids, thereby restricting their local production, fair distribution and widespread availability, which could benefit many farmers in Nepal. Of the estimated 2,500 tons of hybrid maize grown in Nepal annually, only 1,000 tons are registered hybrids.

In 2014 and 2015, the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA) and Nepal’s National Maize Research Program (NMRP) partnered to evaluate maize hybrids in six additional districts (Banke, Bardiya, Kailali, Kanchanpur, Surkhet and Dadeldhura) in western Nepal. Trials were conducted in spring in the Terai and in summer in the mid-hills; they were monitored by a team of NMRP stakeholders. Performance data for variety release and registration were shared with Nepal’s National Seed Board (NSB).

Of the ten hybrids evaluated, four (TX 369, Bioseed 9220, Rajkumar and Nutan) were found to be agronomically superior, producing more than 6 t/ha. They also had tight husk cover, which provides moderate resistance to northern leaf blight and grey leaf spot. Based on the evaluation results, the NSB has registered and approved the four hybrid varieties for sale in western Nepal.

Highlighting the need to increase farmers’ access to registered hybrids, Dilaram Bhandari, NSB member and Director of the Crop Development Directorate of Nepal’s Department of Agriculture, said, “We have to adopt this modality for other hybrids as well, since new hybrids expand outside the recommendation domains quite frequently.”

Maize is not only a staple in diets across sub-Saharan Africa – it is a cash crop that supports millions of farmer households. Maize is grown on over 33 million hectares in just 13 of 48 countries in the region – accounting for 72% of all maize produced in the region. This crop, without a doubt, is king.

However, rising temperatures and erratic rainfall patterns threaten maize production across the continent. Total crop loss occurs if there’s little or no rainfall at the flowering stage, when maize is most vulnerable. And when temperatures increase, soil moisture is quickly depleted and farmers have to resort to prolonged irrigation, a costly undertaking for smallholders.

Drought-tolerant (DT) maize varieties produce better yields both in good and bad seasons compared to most commercial varieties available in the region. Since 2006, CIMMYT has developed 200 drought-tolerant varieties and hybrids, many of which also possess desirable traits such as resistance to major diseases.

quick#In addition to developing quality maize that is high yielding and disease resistant, the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project led by CIMMYT is working to ensure these improved varieties are affordable and attractive to farmers. Two and a half million smallholder farmers in Ethiopia, Kenya, Mozambique, Tanzania, Uganda and Zambia are expected to benefit from in-country partnerships and networks that boost production and distribution of DT maize seed. These countries account for 25 percent (or 252 million) of the population in sub-Saharan Africa, and 41 percent of maize production areas.

To access quality improved seed, farmers in Africa face various constraints such as high prices, low supply and limited knowledge about improved seeds. Through surveys conducted among nearly 5,000 farmer households in Kenya, Mozambique and Zambia, CIMMYT learned that when farmers buy seed, the traits they care most about are early crop maturity, yield, and tolerance/resistance to stresses such as drought and disease. In most cases, long-term use and preference for a particular seed variety influence buying habits, but now farmers are increasingly focusing on tolerance/resistance to drought, pests and diseases.

“Our key focus is on sustainable seed production and increasing demand,” said Kate Fehlenberg, DTMASS project manager. “This means building market skills for producers and creating an environment to entice risk-averse farmers to try new drought-tolerant varieties.”

Gender in seed systemsCIMMYT is working with partners to increase farmer preference for DT seed by supporting promotional and marketing activities, and improving seed production capacity. CIMMYT will also work to ensure local institutions have the technological and production capacity to independently produce and distribute seed throughout DTMASS target countries.

Scaling activities will allow DT seed to spread across various geographical areas (scaling “out”) and build the capacity of local institutions to independently control sustainable seed production (scaling “up”). Both scaling up and out rely on giving stakeholders in the maize value chain compelling reasons to continue producing, distributing and consuming DT maize varieties.

Over 50 selected small- and medium-scale seed companies will be supported through training workshops on seed production and seed business management. Seed companies will also receive financial grants to support expansion activities such as purchasing special seed processing and packing equipment, restoring seed storage and other facilities, and marketing.

The next big challenge for DTMASS is to increase adoption of drought-tolerant maize, which will strengthen seed systems in Africa. Photo: Kelah Kaimenyi/CIMMYT.

From A to Z: Developing nutritious maize and wheat at CIMMYT for 50 years

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.

EL BATAN, Mexico (CIMMYT) – Maize and wheat biofortification can help reduce malnutrition in regions where nutritional options are unavailable, limited or unaffordable, but must be combined with education to be most effective, particularly as climate change jeopardizes food security, according to researchers at the International Maize and Wheat Improvement Center (CIMMYT).

Climate change could kill more than half a million adults in 2050 due to changes in diets and bodyweight from reduced crop productivity, a new report from the University of Oxford states. Projected improvement in food availability for a growing population could be cut by about a third, leading to average per-person reductions in food availability of 3.2 percent, reductions in fruit and vegetable intake of 4 percent and red meat consumption of .07 percent, according to the report.

Over the past 50 years since CIMMYT was founded in 1966, various research activities have been undertaken to boost protein quality and micronutrient levels in maize and wheat to help improve nutrition in poor communities, which the Oxford report estimates will be hardest hit by climate change. As one measure of CIMMYT’s success, scientists Evangelina Villegas and Surinder Vasal were recognized with the prestigious World Food Prize in 2000 for their work developing quality protein maize (QPM).

“We’ve got a lot of balls in the air to tackle the ongoing food security crisis and anticipate future needs as the population grows and the climate changes unpredictably,” said Natalia Palacios, head of maize quality, adding that a key component of current research is the strategic use of genetic resources held in the CIMMYT gene bank.

“CIMMYT’s contribution to boosting the nutritional value of maize and wheat is hugely significant for people who have access to these grains, but very little dietary diversity otherwise. Undernourishment is epidemic in parts of the world and it’s vital that we tackle the problem by biofortifying crops and including nutrition in sustainable intensification interventions.”

Undernourishment affects some 795 million people worldwide – meaning that more than one out of every nine people do not get enough food to lead a healthy, active lifestyle, according to the U.N. Food and Agriculture Organization (FAO).  By 2050, reduced fruit and vegetable intake could cause twice as many deaths as under-nutrition, according to the Oxford report, which was produced by the university’s Future of Food Programme.

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to one-quarter of the world’s daily energy intake, and contributing 27 percent of the total calories in the diets of people living in developing countries, according to FAO.

“Nutrition is very complex and in addition to deploying scientific methods such as biofortification to develop nutritious crops, we try and serve an educational role, helping people understand how best to prepare certain foods to gain the most value,” Palacios said.  “Sometimes communities have access to nutritious food but they don’t know how to prepare it without killing the nutrients.”

The value of biofortified crops is high in rural areas where people have vegetables for a few months, but must rely solely on maize for the rest of the year, she added, explaining that fortified flour and food may be more easily accessed in urban areas where there are more dietary options.

PROMOTING PROTEIN QUALITY

Conventional maize varieties cannot provide an adequate balance of amino acids for people with diets dominated by the grain and with no adequate alternative source of protein. Since the breakthrough findings of Villegas and Vasal, in some areas scientists now develop QPM, which offers an inexpensive alternative for smallholder farmers.

CIMMYT scientists also develop QPM and other nutritious conventionally bred maize varieties for the Nutritious Maize for Ethiopia (NuME) project funded by the government of Canada. NuME, which also helps farmers improve agricultural techniques by encouraging the deployment of improved agronomic practices, builds on a former seven-year collaborative QPM effort with partners in Ethiopia, Kenya, Tanzania and Uganda.

In Ethiopia, where average life expectancy is 56 years of age, the food security situation is critical due in part to drought caused by a recent El Nino climate system, according to the U.N. World Food Programme. More than 8 million people out of a population of 90 million people are in need of food assistance.  Almost 30 percent of the population lives below the national poverty line, 40 percent of children under the age of 5 are stunted, 9 percent are acutely malnourished and 25 percent are underweight, according to the 2014 Ethiopia Mini Demographic and Health Survey. The NuMe project is helping to shore up sustainable food supplies and boost nutrition in the country, where the vast majority of people live in rural areas and are engaged in rain-fed subsistence agriculture.

INCREASING MICRONUTRIENTS

CIMMYT maize and wheat scientists tackle micronutrient deficiency, or “hidden hunger,” through the interdisciplinary, collaborative program HarvestPlus, which was launched in 2003 and is now part of the Agriculture for Nutrition and Health program managed by the CGIAR consortium of agricultural researchers.

Some 2 billion people around the world suffer from micronutrient deficiency, according to the World Health Organization (WHO). Micronutrient deficiency occurs when food does not provide enough vitamins and minerals. South Asia and sub-Saharan Africa are most affected by hidden hunger, which is characterized by iron-deficiency anemia, vitamin A and zinc deficiency.

Work at CIMMYT to combat micronutrient deficiency is aligned with the U.N. Sustainable Development Goals (SDGs) — in particular Goal 2, which aims to end all forms of malnutrition by 2030. The SDG also aims to meet internationally agreed targets on stunting and wasting in children under 5 years of age, and to address the nutritional needs of adolescent girls, older people, pregnant and lactating women by 2025.

WHOLESOME WHEAT

The wheat component of the HarvestPlus program involves developing and distributing wheat varieties with high zinc levels by introducing genetic diversity from wild species and landraces into adapted wheat.

Zinc deficiency affects about one-third of the world’s population, causing lower respiratory tract infections, malaria, diarrheal disease, hypogonadism, impaired immune function, skin disorders, cognitive dysfunction, and anorexia, according to the WHO, which attributes about 800,000 deaths worldwide each year to zinc deficiency. Additionally, worldwide, approximately 165 million children under five years of age are stunted due to zinc deficiency.

A project to develop superior wheat lines combining higher yield and high zinc concentrations in collaboration with national agriculture program partners in South Asia has led to new biofortified varieties 20 to 40 percent superior in grain zinc concentration.

“We’re playing a vital role in this area,” said CIMMYT wheat breeder Velu Govindan. “Our research has led to new varieties agronomically equal to, or superior to, other popular wheat cultivars with grain yield potential at par or — in some cases – even superior to popular wheat varieties adopted by smallholder farmers in South Asia where we’ve been focused.”

Scientists are studying the potential impact of climate-change related warmer temperatures and erratic rainfall on the nutritional value of wheat. An evaluation of the effect of water and heat stress with a particular focus on grain protein content, zinc and iron concentrations revealed that protein and zinc concentrations increased in water and heat-stressed environments, while zinc and iron yield was higher in non-stressed conditions.

“The results of our study suggest that genetic gains in yield potential of modern wheat varieties have tended to reduce grain zinc levels,” Govindan said. “In some instances, environmental variability might influence the extent to which this effect manifests itself, a key finding as we work toward finding solutions to the potential impact of climate change on food and nutrition security.”

Additionally, a recent HarvestPlus study revealed that modern genomic tools such as genomic selection hold great potential for biofortification breeding to enhance zinc concentrations in wheat.

IMPROVING MAIZE

Scientists working with HarvestPlus have developed vitamin A-enriched “orange” maize. Orange maize is conventionally bred to provide higher levels of pro-vitamin A carotenoids, a natural plant pigment found in such orange foods as mangoes, carrots, pumpkins, sweet potatoes, dark leafy greens and meat, converted into vitamin A by the body.

Vitamin A is essential for good eyesight, growth and boosting immunity. Almost 200 million children under the age of 5 and 19 million pregnant women are vitamin A deficient, and increasing levels through maize kernels is an effective means of boosting it in the diet.

Maize breeders, who are currently working on developing varieties with 50 percent more pro-vitamin A than the first commercialized varieties released, identified germplasm with the highest amounts of carotenoids to develop the varieties. In Zambia, Zimbawe and Malawi, 12 varieties, which are agronomically competititve and have about 8ppm provitamin A, have been released.

Provitamin A from maize is efficiently absorbed and converted into vitamin A in the body.  Stores of Vitamin A in 5 to 7 year old children improved when they ate orange maize, according to HarvestPlus research. The study also shows preliminary data demonstrating that children who ate orange maize for six months experienced an improved capacity of the eye to adjust to dim light. The findings indicate an improvement in night vision, a function dependent on adequate levels of vitamin A in the body.

Researchers are also developing maize varieties high in zinc.

Efforts on this front have been a major focus in Latin America, especially in Nicaragua, Guatemala and Colombia. Scientists expect the first wave of high zinc hybrids and varieties will be released in 2017. Further efforts are starting in such countries as Zambia, Zimbabwe and Ethiopia. Results from the first nutrition studies in young rural Zambian children indicate that biofortified maize can meet zinc requirements and provide an effective dietary alternative to regular maize for the vulnerable population.

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.

 

Harnessing partnerships to build maize seed production and businesses in South Asia

HYDERABAD, INDIA — A training course on maize seed production and seed business management was organized by CIMMYT and seed companies Pioneer Hi-bred and Kaveri Seeds from 28-30 March, 2016. The training was held as part of the CIMMYT’s efforts to connect several public and private sector agricultural research institutions in South Asia.

South Asian farmlands have been increasingly experiencing climate change-related weather extremes. If current trends persist until 2050, major crop yields and the food production capacity of South Asia will decrease significantly – by 17 percent for maize – due to climate change-induced heat and water stress. In response to this situation, CIMMYT with support from the United States Agency for International Development and partners are developing heat stress-resilient maize for Asia.

The course aimed to strengthen the capacity of partner institutions – particularly small-and-medium enterprises and national agricultural research systems in South Asia –  to expand their maize seed production processes and increase uptake of heat-resilient maize hybrids in stress-prone areas.  More than 20 participants from partner institutions participated in the course including breeders, seed production specialists and seed business specialists from commercial seed companies, including Syngenta, DuPont Pioneer, Advanta, J.K. Seeds, CIMMYT and the International Crops Research Institute for the Semi-Arid Tropics.

“Public-private alliances are critical to address complex issues such as heat stress and the development and deployment of heat stress-resilient maize in different regions of South Asia,” said P.H. Zaidi, CIMMYT’s Heat Stress Tolerant Maize for Asia (HTMA) project leader and senior maize physiologist. Zaidi also presented HTMA updates and listed the first variety releases licensed in 2015 to various partners for deployment.

Selvarajan Venkatesh, DuPont Pioneer senior maize breeder, gave a talk on commercial plant breeding and its business perspective with respect to sustainability and foundation for global food security. Venkatesh elaborated on how modern sophisticated hi-tech tools and interactions with multidisciplinary departments changed the face of present plant breeding. Nagesh Patne, CIMMYT seed system project Scientist, discussed the importance of seed production research and the optimization process of the cost of goods of seeds. Various aspects of plant characterization for seed production feasibility were also discussed during this meeting.

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.”
