Fight against fall armyworm in Asia benefits from experience in other regions

When the destructive fall armyworm arrived in Asia in the summer of 2018, scientists were not taken by surprise. They had been anticipating its arrival on the continent as the next stage of its aggressive eastward journey, driven by changing climatic conditions and international trade routes. The pest, native to North and South America, had invaded and spread throughout most of sub-Saharan Africa within two years, severely damaging billions of dollars of maize crops and threatening food security for millions of people. Asian countries would have to mobilize quickly to cope with this new threat.

After reaching India in 2018, the pest spread to other parts of Asia, including Bangladesh, mainland China, Indonesia, Laos, Myanmar, Nepal, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.

Fall armyworm is a major threat to Asia’s maize farmers, many of whom derive a crucial source of household income by selling maize as feed grain for the growing poultry sector. What is not sold is paramount for subsistence and daily nutrition in communities in the hills of Nepal, in the tribal regions of India, in the mountainous provinces of southern China, and in parts of Indonesia and the Philippines.

The pest is here to stay

Fall armyworm cannot be eradicated — once it has arrived in an agro-ecosystem, farmers must learn how to cope with it. Farmers in the Americas have lived with this pest for the last two hundred years, but their tools and management techniques cannot be simply applied in Africa or Asia. Solutions need to be tailored to specific countries and local contexts, to account for the vast differences in local ecologies, practices, policies and other conditions.

Timothy J. Krupnik and B.M. Prasanna are two of the scientists responding to fall armyworm in Asia. Both are with the International Maize and Wheat Improvement Center (CIMMYT). As a long-established organization with global presence, CIMMYT had decades of experience managing fall armyworm in its native lands before the global spread started. These scientists see the enormous threat to maize crops in Asia, and the negative impact it could have on the income and wellbeing of smallholders and their families, but they also point to opportunities to develop, validate and deploy effective solutions.

In South Asia, farmers have developed intensive agricultural techniques to produce food for rapidly growing populations, meaning agricultural inputs such as seeds, fertilizer and pesticides are more readily available than in much of Africa. The private sector is generally good at getting solutions to farmers, who are often willing and able to adopt new ways of farming. “The private sector in South Asia is in a good position to exchange and transfer technologies across the region,” explains Prasanna, who leads CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.

The accessibility of pesticides also has its risks, says Krupnik, a senior scientist based in Bangladesh. “If used incorrectly, pesticides can be unsafe, environmentally damaging and even ineffective,” he says. Krupnik’s team is currently engaging with pesticide companies in Bangladesh, helping them develop an evidence-based response to fall armyworm. “We want to encourage effective, environmentally safer solutions such as integrated pest management that cause least harm to people and ecosystems,” he explained.

A global effort

The global nature of the challenge may have a silver lining. “Over the last three years, we have learned important lessons on fall armyworm management in Africa, including what technologies work and why,” says Prasanna. “With the pest now a global problem, there is great potential for cooperation among affected countries, especially between Africa and Asia.”

Researchers emphasize that a collective effort is needed to respond to the fall armyworm in Asia. CIMMYT is working with partners around the world to help leverage and share expertise and technologies across borders.

China has as much acreage of maize as the whole African continent, and has tremendous institutional expertise and capacity to deal with new challenges, explains Prasanna. His team is in discussions with Chinese researchers to share knowledge and solutions across Asia.

Bangladesh and Nepal are among the countries seeking linkages with international experts and researchers in other countries.

In Africa, CIMMYT was part of a global coalition of scientists and governments who joined forces in 2017 to tackle the fall armyworm threat and develop scientific solutions. The researchers want to see this approach expand into Asia, supported by the donor community.

As the pest continues its relentless expansion in the region, extensive work is ahead for both research and development institutions. Researchers need to identify and promote best management practices. Technologies will have to be environmentally sustainable, durable and inclusive, says Prasanna.

Joining hands

“To achieve this, we need a multidisciplinary team including breeders, pest management experts, seed specialists, agronomists and socioeconomists, who can share science-based evidence with development partners, governments and farmers,” Prasanna says.

CIMMYT researchers are on the path towards developing improved maize varieties with native genetic resistance to fall armyworm. They are also engaging with farming communities to make sure other integrated pest management solutions are available.

In addition to developing agronomic practices and technologies, scientists are reaching out to farming communities with the right messages, Krupnik explains. “As well as being technical experts, our scientists are embedded in the countries where we work. We’ve lived here for a long time, and understand how to engage with local partners,” he says.

Cross-border collaboration and knowledge transfer is already happening. Partners in Laos enthusiastically adapted fall armyworm informational materials from Bangladesh for local dissemination. Krupnik and his team have also collaborated on a video with guidance on how to identify and scout for fall armyworm in a field, developed by Scientific Animations without Borders.

Fall armyworm will continue its spread across Asia, and researchers will have many questions to answer, such as how fall armyworm interacts with very diverse Asian agro-ecosystems, the pest population dynamics, and measuring the economic impacts of interventions. Solutions need to be developed, validated and deployed for the short, medium and long term. Krupnik and Prasanna hope that international cooperation can support these crucial research-for-development activities.

“Fall armyworm is here to stay. We are running a marathon and not a 100-meter sprint,” proclaimed Prasanna. “Let’s work collectively and strategically so that the farmer is the ultimate winner.”

It’s time to change the system, not just the technology

Society faces enormous challenges in the transition to sustainable rural development. We are unlikely to make this transition unless we move away from the 20th-century paradigm that sees the world as a logical, linear system focused on “scaling up” the use of technologies to reach hundreds of millions of smallholders.

In a new article published this week on NextBillion, Lennart Woltering of CIMMYT contends that “farming communities are unlikely to continue using a new practice or technology if the surrounding system remains unchanged, since it is this very system that shaped their conventional way of farming.”

Woltering calls on the research for development community to work towards producing deeper system change and offers some key considerations for moving in the right direction.

The man who fed the world

Norman Borlaug was awarded the Nobel Peace Prize in 1970 in recognition of his contributions to world peace through increasing food production. In the latest episode of the BBC radio show Witness History, Rebecca Kesby interviews Ronnie Coffman, student and friend of Norman Borlaug.

Among other stories, Coffman recalls the moment when Borlaug was notified about the Nobel Prize — while working in the wheat fields in Mexico — and explores what motivated Borlaug to bring the Green Revolution to India.

The cereals imperative of future food systems

Pioneering research on our three most important cereal grains — maize, rice, and wheat — has contributed enormously to global food security over the last half century, chiefly by boosting the yields of these crops and by making them more resilient in the face of drought, flood, pests and diseases. But with more than 800 million people still living in chronic hunger and many more suffering from inadequate diets, much remains to be done. The challenges are complicated by climate change, rampant degradation of the ecosystems that sustain food production, rapid population growth and unequal access to resources that are vital for improved livelihoods.

In recent years, a consensus has emerged among agricultural researchers and development experts around the need to transform global food systems, so they can provide healthy diets while drastically reducing negative environmental impacts. Certainly, this is a central aim of CGIAR — the world’s largest global agricultural research network — which views enhanced nutrition and sustainability as essential for achieving the Sustainable Development Goals. CGIAR scientists and their many partners contribute by developing technological and social innovations for the world’s key crop production systems, with a sharp focus on reducing hunger and poverty in low- and middle-income countries of Africa, Asia and Latin America.

The importance of transforming food systems is also the message of the influential EAT-Lancet Commission report, launched in early 2019. Based on the views of 37 leading experts from diverse research disciplines, the report defines specific actions to achieve a “planetary health diet,” which enhances human nutrition and keeps the resource use of food systems within planetary boundaries. While including all food groups — grains, roots and tubers, pulses, vegetables, fruits, tree nuts, meat, fish, and dairy products — this diet reflects important shifts in their consumption. The major cereals, for example, would supply about one-third of the required calories but with increased emphasis on whole grains to curb the negative health effects of cheap and abundant supplies of refined cereals.

This proportion of calories corresponds roughly to the proportion of its funding that CGIAR currently invests in the major cereals. These crops are already vital in diets, cultures, and economies across the developing world, and the way they are produced, processed and consumed must be a central focus of global efforts to transform food systems. There are four main reasons for this imperative.

1. Scale and economic importance

The sheer extent of major cereal production and its enormous value, especially for the poor, account in large part for the critical importance of these crops in global food systems. According to 2017 figures, maize is grown on 197 million hectares and rice on more than 167 million hectares, mainly in Asia and Africa. Wheat covers 218 million hectares, an area larger than France, Germany, Italy, Spain and the UK combined. The total annual harvest of these crops amounts to about 2.5 billion tons of grain.

Worldwide production had an estimated annual value averaging more than $500 billion in 2014-2016. The prices of the major cereals are especially important for poor consumers. In recent years, the rising cost of bread in North Africa and tortillas in Mexico, as well as the rice price crisis in Southeast Asia, imposed great hardship on urban populations in particular, triggering major demonstrations and social unrest. To avoid such troubles by reducing dependence on cereal imports, many countries in Africa, Asia and Latin America have made staple crop self-sufficiency a central element of national agriculture policy.

2. Critical role in human diets

Cereals have a significant role to play in food system transformation because of their vital importance in human diets. In developing countries, maize, rice, and wheat together provide 48% of the total calories and 42% of the total protein. In every developing region except Latin America, cereals provide people with more protein than meat, fish, milk and eggs combined, making them an important protein source for over half the world’s population.

Yellow maize, a key source of livestock feed, also contributes indirectly to more protein-rich diets, as does animal fodder derived from cereal crop residues. As consumption of meat, fish and dairy products continues to expand in the developing world, demand for cereals for food and feed must rise, increasing the pressure to optimize cereal production.

In addition to supplying starch and protein, the cereals serve as a rich source of dietary fiber and nutrients. CGIAR research has documented the important contribution of wheat to healthy diets, linking the crop to reduced risk of type 2 diabetes, cardiovascular disease, and colorectal cancer. The nutritional value of brown rice compared to white rice is also well known. Moreover, the recent discovery of certain genetic traits in milled rice has created the opportunity to breed varieties that show a low glycemic index without compromising grain quality.

3. Encouraging progress toward better nutritional quality

The major cereals have undergone further improvement in nutritional quality during recent years through a crop breeding approach called “biofortification,” which boosts the content of essential vitamins or micronutrients. Dietary deficiencies of this kind harm children’s physical and cognitive development, and leave them more vulnerable to disease. Sometimes called “hidden hunger,” this condition is believed to cause about one-third of the 3.1 million annual child deaths attributed to malnutrition. Diverse diets are the preferred remedy, but the world’s poorest consumers often cannot afford more nutritious foods. The problem is especially acute for women and adolescent girls, who have unequal access to food, healthcare and resources.

It will take many years of focused effort before diverse diets become a reality in the lives of the people who need them most. Diversified farming systems such as rice-fish rotations that improve nutritional value, livelihoods and resilience are a step in that direction. In the meantime, “biofortified” cereal and other crop varieties developed by CGIAR help address hidden hunger by providing higher levels of zinc, iron and provitamin A carotenoids as well as better protein quality. Farmers in many developing countries are already growing these varieties.

A 2018 study in India found that young children who ate zinc-biofortified wheat in flatbread or porridge became ill less frequently. Other studies have shown that consumption of provitamin A maize improves the body’s total stores of this vitamin as effectively as vitamin supplementation. Biofortified crop varieties are not a substitute for food fortification (adding micronutrients and vitamins during industrial food processing). But these varieties can offer an immediate solution to hidden hunger for the many subsistence farmers and other rural consumers who depend on locally produced foods and lack access to fortified products.

4. Wide scope for more sustainable production

Cereal crops show much potential not only for enhancing human heath but that of the environment as well. Compared to other crops, the production of cereals has relatively low environmental impact, as noted in the EAT-Lancet report. Still, it is both necessary and feasible to further enhance the sustainability of cereal cropping systems. Many new practices have a proven ability to conserve water as well as soil and land, and to use purchased inputs (pesticides and fertilizers) far more efficiently. With innovations already available, the amount of water used in current rice cultivation techniques, for example, can be significantly reduced from its present high level.

Irrigation scheduling, laser land leveling, drip irrigation, conservation tillage, precision nitrogen fertilization, and cereal varieties tolerant to drought, flooding and heat are among the most promising options. In northwest India, scientists recently determined that optimal practices can reduce water use by 40%, while maintaining yields in rice-wheat rotations. There and in many other places, the adoption of new practices to improve cereal production in the wet season not only leads to more efficient resource use but also creates opportunities to diversify crop production in the dry season. Improvements to increase cereal crop yields also reduces their environmental footprint; using less land, enhancing carbon sequestration and biodiversity and, for rice, reducing methane emissions per kilo of rice produced. Given the enormous extent of cereals cultivation, any improvement in resource use efficiency will have major impact, while also freeing up vast amounts of land for other crops or natural vegetation.

A major challenge now is to improve access to the knowledge and inputs that will enable millions of farmers to adopt new techniques, making it possible both to diversify production and grow more with less. Another key requirement consists of clear signals from policymakers, especially where land and water are limited, about the priority use of these resources — for example, irrigating low-value cereals to bolster food security versus applying the water to higher value crops and importing staple cereals.

Toward a sustainable dietary revolution

Future-proofing the global food system requires bold steps. Policy and research need to support a double transformation, centered on nutrition and sustainability.

CGIAR works toward nutritional transformation of our food system through numerous global partnerships. We give high priority to improving cereal crop systems and food products, because of their crucial importance for a growing world population. Recognizing that this alone will not suffice for healthy diets, we also strongly promote greater dietary diversity through our research on various staple crops and production systems and by raising public awareness of more balanced and nutritious diets.

To help achieve a sustainability transformation, CGIAR researchers and partners have developed a wide array of techniques that use resources more efficiently, enhance the resilience of food production in the face of climate change and reduce greenhouse gas emissions, while achieving sustainable increases in crop yields. At the same time, we are generating new evidence on which techniques work best under what conditions to target the implementation of these solutions more effectively.

The ultimate impact of our work depends crucially on the growing resolve of developing countries to promote better diets and more sustainable food production through strong policies and programs. CGIAR is well prepared to help strengthen these measures through research for development, and we are confident that our work on cereals, with continued donor support, will have high relevance, generating a wealth of innovations that help drive the transformation of global food systems.

Microsatellite data can help double impact of agricultural interventions

Data from microsatellites can be used to detect and double the impact of sustainable interventions in agriculture at large scales, according to a new study led by the University of Michigan (U-M).

By being able to detect the impact and target interventions to locations where they will lead to the greatest increase of yield gains, satellite data can help increase food production in a low-cost and sustainable way.

According to the team of researchers from U-M, the International Maize and Wheat Improvement Center (CIMMYT), and Stanford and Cornell universities, finding low-cost ways to increase food production is critical, given that feeding a growing population and increasing the yields of crops in a changing climate are some of the greatest challenges of the coming decades.

“Being able to use microsatellite data, to precisely target an intervention to the fields that would benefit the most at large scales will help us increase the efficacy of agricultural interventions,” said lead author Meha Jain, assistant professor at the U-M School for Environment and Sustainability.

Microsatellites are small, inexpensive, low-orbiting satellites that typically weigh 100 kilograms or less.

“About 60-70% of total world food production comes from smallholders, and they have the largest field-level yield gaps,” said Balwinder Singh, senior researcher at the International Maize and Wheat Improvement Center (CIMMYT).

To show that the low-cost microsatellite imagery can quantify and enhance yield gains, the researchers conducted their study in smallholder wheat fields in the Eastern Indo-Gangetic Plains in India.

They ran an experiment on 127 farms using a split-plot design over multiple years. In one half of the field, the farmers applied nitrogen fertilizer using hand broadcasting, the typical fertilizer spreading method in this region. In the other half of the field, the farmers applied fertilizer using a new and low-cost fertilizer spreader.

To measure the impact of the intervention, the researchers then collected the crop-cut measures of yield, where the crop is harvested and weighed in field, often considered the gold standard for measuring crop yields. They also mapped field and regional yields using microsatellite and Landsat satellite data.

They found that without any increase in input, the spreader resulted in 4.5% yield gain across all fields, sites and years, closing about one-third of the existing yield gap. They also found that if they used microsatellite data to target the lowest yielding fields, they were able to double yield gains for the same intervention cost and effort.

“Being able to bring solutions to the farmers that will benefit most from them can greatly increase uptake and impact,” said David Lobell, professor of earth system science at Stanford University. “Too often, we’ve relied on blanket recommendations that only make sense for a small fraction of farmers. Hopefully, this study will generate more interest and investment in matching farmers to technologies that best suit their needs.”

The study also shows that the average profit from the gains was more than the amount of the spreader and 100% of the farmers were willing to pay for the technology again.

Jain said that many researchers are working on finding ways to close yield gaps and increase the production of low-yielding regions.

“A tool like satellite data that is scalable and low-cost and can be applied across regions to map and increase yields of crops at large scale,” she said.

Ethiopian policymakers consider wider use of DNA fingerprinting

How to track adoption and assess the impact of maize and wheat varieties? Some of the methods used until now, like farmers’ recall surveys, have various limitations. In addition to relying exclusively on people’s memory and subjectivity, they are difficult to replicate and prone to errors.

DNA fingerprinting, on the other hand, allows objective evaluation and is considered the “gold standard” method for adoption and impact assessments.

It consists of a chemical test that shows the genetic makeup of living things, by separating strands of DNA and revealing the unique parts of their genome. The results show up as a pattern of stripes that can be matched against other samples.

This technique is extremely helpful in tracking crop varieties and monitoring their adoption. It can be used to assess the impact of research-for-development investments, guide breeding and seed system strategies, implement the intellectual property rights of breeders, assess the use of crop genetic resources, and informing policy.

On June 25, 2019, the International Maize and Wheat Improvement Center (CIMMYT) held a half-day workshop in Addis Ababa to discuss the use and application of DNA fingerprinting in Ethiopia for the tracking of crop varieties.

High-level government officials and major players in the agricultural sector were interested in learning more about the policy implications of this tool and how to mainstream its use.

Introducing DNA fingerprinting in Ethiopia

The main DNA fingerprinting project in Ethiopia has been in operation since January 2016, focusing on the country’s two major staple crops: wheat and maize. The project covers the Amhara, Oromia, SNNPR, and Tigray regions, which together account for 92% and 79% of the national wheat and maize production.

The Bill & Melinda Gates Foundation has funded the project, which was jointly implemented by CIMMYT, the Ethiopian Institute of Agricultural Research (EIAR), Ethiopia’s Central Statistical Agency (CSA) and Diversity Arrays Technology (DArT).

The main objective of the project was to generate a knowledge base for the practical use of DNA fingerprinting, to mainstream the use of this technology, and to offer policy options and recommendations.

Better monitoring for wheat self-sufficiency

At the workshop, researchers presented two policy briefs specific to Ethiopia: one focusing on policy implications of DNA fingerprinting for tracking bread wheat varieties and another one on how to revitalize the durum wheat sub-sector.

Speaking at the workshop, Eyasu Abraha, Minister of Agriculture and Natural Resources, noted that the government planned to achieve wheat grain self-sufficiency in the next few years by increasing wheat productivity in the highlands and expanding wheat production to the lowlands through irrigation.  In this regard, improved crop variety development and dissemination is one of the key elements to increase agricultural productivity and improve the livelihood of millions of smallholder farmers.

According to Abraha, more than 130 wheat varieties have been released or registered in Ethiopia since the late 1960s, in collaboration with international research organizations. Public and private seed enterprises have multiplied and distributed these varieties to reach smallholder farmers.

Even though adoption studies have been conducted, there is still a strong need for more accurate and wider studies. In addition to tracking adoption and demand, using DNA fingerprinting could help understand the distribution of varieties across space and time.

Embracing change: How family farmers can face the future

This year opens the Decade of Family Farming (#FamilyFarmingDecade), which aims to improve the life of family farmers around the world. In an earnest discussion, two leaders in the global agriculture community reflect on the challenges facing family farmers, the promises of high- and low-tech solutions, and their hopes for the future.

A conversation between Martin Kropff, Director General of the International Maize and Wheat Improvement Centre (CIMMYT) and Trevor Nicholls, CEO of CABI.

On the unique challenges facing family farms

Trevor Nicholls (CABI): Family farmers come in many shapes and sizes but for me, the words “family farmer” bring a focus on smallholders and people who are starting on a journey of making a farming business. It depends on which part of the world you’re talking about; a family farm in the UK is perhaps very different to a small family farm in Ethiopia. And family farms can grow from just a small plot to being quite large commercial enterprises.

Martin Kropff (CIMMYT): All agriculture started with family farms. Fifty years ago in my home country, the Netherlands, farms were almost all family farms. When we look globally, farms in places like India, Pakistan, and Kenya are very often small, and the whole family is involved.

KROPFF: When the whole family is involved, gender dynamics come out. In a way, family farming is very often the farming done by women. This makes women the most important players in agriculture in many developing countries. It’s crucial to recognize this and understand their decision-making. For example, our research shows that men and women value different traits in crop varieties. We need to understand this to have successful interventions.

NICHOLLS: We’ve seen something similar through our Plantwise plant clinics, where farmers come for practical plant health advice. We see a definite pattern of men bringing in cash crops for advice, and women looking more at fruits and vegetables to feed their family. But overall, mostly men come into our clinics, particularly in certain parts of the world. We’re trying to encourage more female participation by timing the clinics so that they fit into women’s routines without getting in the way of taking care of elderly relatives or getting kids off to school. Sometimes really simple things can open up access and improve the gender balance.

KROPFF: When the whole family is involved, there are also downsides. In Africa, young people do much of the weeding.

NICHOLLS: That’s right, they may be pulled out of school for weeding.

KROPFF: This really worries me. Hand weeding is such hard labor, such an intensive use of energy; it seems like it should be something of the past. Children don’t want to do it anymore. My wife is from the generation where children still did weeding in the Netherlands. She remembers standing in the fields weeding when the sun was extremely warm while her friends were out doing other things.

NICHOLLS: It starts kids off on the wrong path, doesn’t it? If their experience of farming is backbreaking weeding from the age of 8 onwards, it’s highly unlikely to attract them into farming as a career.

On keeping young people interested in farming

NICHOLLS: We need to look at things like weed control as a social issue. It’s possible, for example, to use beneficial insects to limit the spread of certain weeds that infest farmland. Biocontrol and Integrated Pest Management should be seen as ways of reducing the spread of certain weeds, and also as ways to reduce the burden on women and youth.

KROPFF: I agree. Similarly, we’re finding that small-scale mechanization is making a difference for youth, and also women’s labor in Latin America, Africa and Asia, where CIMMYT has been introducing two-wheel tractors that can be engineered in local workshops. Suddenly, smallholders can harvest the entire wheat crop of 20 families in one day. This saves so much time, money, and effort, eliminating some of the “bad” labor that may discourage youth and unfairly burden women. Farmers can focus on the “nice” aspects of the business. It’s a real game changer for family farming.

NICHOLLS: Yes and this can also be amplified through digital technology. People refer to the “Uber-ization” of tractors, where farmers are able to hire a piece of mechanical equipment for a very short space of time, and maybe it even comes with an experienced driver or operator. We’re finding that digital tools like artificial intelligence, satellite imaging, smartphones, and other modern technologies, will intrigue youth anywhere in the world. These will hopefully have an impact on bringing more youth back into farming, as they start to see it as technologically enabled rather than straightforward muscle power.

On the transformations that need to happen

KROPFF: If we want to keep youth engaged, and improve farmers’ livelihoods, I think farming needs to become more entrepreneurial. Many family farms are only half a hectare. I think this has to grow somehow, though land rights and ownership are a challenge

NICHOLLS: As farming becomes more business-like in Africa then we’re going to see the same sort of consolidation that we saw in the United States and Europe, whereby farm sizes do get larger even if land ownership remains fragmented.

This could happen through cooperatives, which offer economies of scale and also help farmers spread the costs of things like access to inputs, advice, weather insurance and crop insurance. But we need to view cooperatives as more than a way to infuse new technologies into the farming system. They are in fact a channel for helping farmers gain stronger business skills, so they can get a better bargain for themselves.

KROPFF: In Mexico we are working with 300,000 smallholder farmers in a sustainable maize and wheat sourcing initiative. Rather than “pushing” new varieties and technologies at farmers, we help them partner with maize and wheat companies to create a local demand for high quality, sustainable products. Real scaling up, especially for wheat and maize, needs more than extension. Farmers need better links to the market.

NICHOLLS: If farms get larger and more mechanized, it means fewer people are involved in the business of farming. This shift means that people will need other rural occupations, so that they don’t just leave the land and move to the city. We need investments in other productive activities in rural areas. This could be around post-harvest processing of crops: adding value locally rather than shipping the raw materials elsewhere.

KROPFF: Exactly. We’ve been doing more work on this in the last ten years. CIMMYT works on wheat and maize, and these are products that need to be processed. Doing this locally would also help people save food in the future for more difficult times, instead of selling to someone from the city who may buy it for an unfair price. Farmers these days have access via smartphones to market information, which is empowering. We see it happening in Africa. It’s really crucial.

NICHOLLS: We’re certainly seeing the power of digital technologies, which are also helping us move beyond just responding to crop pests and diseases to being able to get better at predicting outbreaks on a micro-scale. By linking ground observations through our Plantwise clinics with satellite observation technology and data, we’ve developed a program called PRISE (Pest Risk Information SErvice), which provides farmers with alerts before a pest is likely to reach its peak point, so that they can be prepared and take preventative measures.

KROPFF: Without a doubt, smallholder farmer communities are rapidly entering the digital age, and tools on weather prediction, selection of varieties, market information are very important and transforming the way people farm.

On climate change

KROPFF: Climate change is going to be the issue affecting family farmers, especially in Asia and Africa where the population will grow by 2 billion people who need food that has been produced on their own continents. Yields have to rise and climate change brings yields down. We have to help smallholder family farmers keep doing their job and ensure crop yields, which is why climate change is embedded into 70% of our work at CIMMYT. One major area is developing and testing heat- and drought-tolerant varieties that suit local climates. Last year I was in Zimbabwe, which was experiencing El Niño, and I was very impressed by the difference in maize yields from drought and heat-tolerant varieties compared to the normal varieties.

NICHOLLS: That’s very good. In addition to drought and heat, we see pests and diseases appearing in new places as a result of climate change. Pests and diseases will cause crop losses of up to 40% on average. Stemming those losses is critical. We’re seeing invasive species, such as fall armyworm, and many invasive weeds and trees that are effectively stealing arable and pastoral land from farmers, as well as water resources.

Pest-resistant crops have great long-term potential, but farmers also need short-term solutions while they wait for new varieties to become available. One of CABI’s strengths is scanning for solutions from other parts of the world. With fall armyworm, we are looking to South America, where the pest originates, for solutions and natural enemies. We’re also scanning our fungal culture collection for samples that may have properties that can form the basis for biopesticides, and therefore open up a program of biological control.

Hopes for the future

NICHOLLS: I’m very optimistic for family farmers. They are incredibly resilient and resourceful people, and they survive and thrive in pretty difficult circumstances. But the world is getting more challenging for them by the day. I think the Sustainable Development Goals (SDGs) have framed many of the issues very well, in terms of food security and livelihoods, sustainable consumption and production, and this will help to focus attention on family farmers.

I do see some quite encouraging signs, particularly in Africa, where the CAADP (Comprehensive Africa Agricultural Development Programme) has brought much greater coordination among countries. We’re seeing more unity in the requests we receive from our member countries to help them address the issues that are in the SDGs. That makes the work of our organizations easier, because we’re addressing a broader set of demands. And in turn, that will benefit family farmers.

Technology, be it biotechnology or telecommunications and ICTs, is becoming so much more affordable over time. The rate that smartphone usage is spreading in Africa and Asia is incredible. In many areas we actually have most of the technology we need today. It’s about getting it put into practice effectively with large numbers of farmers. So I remain very optimistic about the future.

KROPFF: I’m an optimist by nature. That’s also why I’m in this job: it’s not easy, but I really believe that change is possible if we have our act together and collaborate with CABI and other international research partners, national systems and the private sector. For a long time, people said that there was no Green Revolution in Africa, where yields remained one ton per hectare. But today we see yields increasing in countries like Nigeria, and in Ethiopia, where maize yields are 3.5 tons per hectare. Good things are happening because of family farming.

I believe that to increase yields you need three components: better seeds for more resilient crop varieties; sustainable intensification to grow more nutritious food per unit of water, land and soil; and good governance, to properly manage resources. We need to invest in all of these areas.

NICHOLLS: I fully agree. We need to work on all these areas, and harness the power of modern technology to help family farmers thrive now, and in the future.

Extensive use of wild grass-derived “synthetic hexaploid wheat” adds diversity and resilience to modern bread wheat

In a new study, scientists have found that genome segments from a wild grass are present in more than one in five of elite bread wheat lines developed by the International Maize and Wheat Improvement Center (CIMMYT).

Scientists at CIMMYT and other research institutes have been crossing wild goat grass with durum wheat — the wheat used for pasta — since the 1980s, with the help of complex laboratory manipulations. The new variety, known as synthetic hexaploid wheat, boosts the genetic diversity and resilience of wheat, notoriously vulnerable due to its low genetic diversity, adding novel genes for disease resistance, nutritional quality and heat and drought tolerance.

The study, which aimed to measure the effect of these long-term efforts using state-of-the-art molecular technology, also found that 20% of CIMMYT modern wheat lines contain an average of 15% of the genome segments from the wild goat grass.

“We’ve estimated that one-fifth of the elite wheat breeding lines entered in international yield trials has at least some contribution from goat grass,” said Umesh Rosyara, genomic breeder at CIMMYT and first author of the paper, which was published in Nature Scientific Reports. “This is much higher than expected.”

Although the synthetic wheat process can help bring much-needed diversity to modern wheat, crossing with synthetic wheat is a complicated process that also introduces undesirable traits, which must later be eliminated during the breeding process.

“Many breeding programs hesitate to use wild relatives because undesirable genomic segments are transferred in addition to desirable segments,” said Rosyara. “The study results can help us devise an approach to quickly eliminate undesirable segments while maintaining desirable diversity.”

CIMMYT breeding contributions are present in nearly half the wheat sown worldwide, many of such successful cultivars have synthetic wheat in the background, so the real world the impact is remarkable, according to Rosyara.

“With this retrospective look at the development and use of synthetic wheat, we can now say with certainty that the best wheat lines selected over the past 30 years are benefiting from the genes of wheat’s wild relatives,” he explained. “Even more, using cutting-edge molecular marker technology, we should be able to target and capture the most useful genes from wild sources and better harness this rich source of diversity.”

Modern breeders tread in nature’s footsteps

The common bread wheat we know today arose when an ancient grain called emmer wheat naturally cross-bred with goat grass around 10,000 years ago. During this natural crossing, very few goat grass genes crossed over, and as a result, current bread wheat is low in diversity for the genome contributed by goat grass. Inedible and considered a weed, goat grass still has desirable traits including disease resistance and tolerance to climate stresses.

Scientists sought to broaden wheat’s genetic diversity by re-enacting the ancient, natural cross that gave rise to bread wheat, crossing improved durum wheat or primitive emmer with different variants of goat grass. The resulting synthetic wheats were crossed again with improved wheats to help remove undesirable wild genome segments.

Once synthetic wheat is developed, it can be readily crossed with any elite wheat lines thus serving as a bridge to transfer diversity from durum wheat and wild goat grass to bread wheat. This helps breeders develop high yielding varieties with desirable traits for quality varieties and broad adaption.

CIMMYT is the first to use wheat’s wild relatives on such a large scale, and the synthetic derivative lines have been used by breeding programs worldwide to develop popular and productive bread wheat varieties. One example, Chuanmai 42, released in China in 2003, stood as the leading wheat variety in the Sichuan Basin for over a decade. Other synthetic derivative lines such as Sokoll and Vorobey appear in the lineage of many successful wheat lines, contributing crucial yield stability — the ability to maintain high yields over time under varying conditions.

The successful, large-scale use of genes from wheat’s wild relatives has helped broaden the genetic diversity of modern, improved bread wheat nearly to the level of the crop’s heirloom varieties. This diversity is needed to combat future environmental, pest, and disease challenges to the production of a grain that provides 20% of the calories consumed by humans worldwide.

This work was supported by the CGIAR Research Program on Wheat (WHEAT) and Seeds of Discovery (SeeD), a multi-project initiative comprising MasAgro Biodiversidad, a joint initiative of CIMMYT and the Ministry of agriculture and rural development (SADER) through the MasAgro (Sustainable Modernization of Traditional Agriculture) project; the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT); and a computation infrastructure and data analysis project supported by the UK’s Biotechnology and Biological Sciences Research Council (BBSRC).  CIMMYT’s worldwide partners participated in the evaluation of CIMMYT international wheat yield trials.

Nepal’s seed sector partners join forces to realize the National Seed Vision 2013-2025

Access to affordable quality seed is one of the prerequisites to increase agricultural production and improve the livelihoods of Nepali farmers. However, there are significant challenges to boost Nepal’s seed industry and help sustainably feed a growing population.

Six years ago, Nepal launched its National Seed Vision 2013-2025. This strategic plan aims at fostering vibrant, resilient, market-oriented and inclusive seed systems in public-private partnership modalities, to boost crop productivity and enhance food security.

The Nepal Seed and Fertilizer (NSAF) project, led by the International Maize and Wheat Improvement Center (CIMMYT), is supporting the government to enhance national policies and guidelines, and private seed companies to build competitive seed businesses and hybrid seed production.

Quality seed can increase crop yield by 15-20%. However, there are critical challenges hindering the growth of Nepal’s seed industry. Existing seed replacement rate for major cereals is low, around 15%. About 85% of Nepali farmers are unable to access recently developed improved seeds — instead, they are cultivating decades-old varieties with low yield and low profits. Some of the factors limiting the development of seed systems are the high cost of seed production and processing, the limited reach of mechanization, and the low use of conservation agriculture practices.

The demand for hybrid seeds in Nepal is soaring but research in variety development is limited. Most of the country’s supply comes from imports.

In collaboration with the Nepal Agricultural Research Council (NARC), the NSAF project team is working with seed companies and cooperatives to scale hybrid seed production of maize, tomato and rice. Through this project, CIMMYT collaborated with the Seed Quality Control Center (SQCC) and national commodity programs of the NARC to draft the first hybrid seed production and certification guidelines for Nepal to help private seed companies produce and maintain standards of hybrid seeds.

Extension and promotion activities are essential to bring improved seed varieties to farmers. Standard labelling and packaging also needs to be strengthened.

A joint effort

CIMMYT and its partners organized a two-day workshop to review the progress of the National Seed Vision. The event attracted 111 participants from government institutions, private companies and development organizations engaged in crop variety development, seed research, seed production and dissemination activities.

In the opening remarks, Yubak Dhoj G.C., Secretary of Nepal’s Ministry of Agriculture and Livestock Development, addressed the seed sector scenario and its challenges. He stressed the importance of collaboration among seed stakeholders to meet the targets of the National Seed Vision in the next six years.

During the technical sessions, Madan Thapa, Chief of the SQCC, analyzed the current status of the National Seed Vision and highlighted the challenges as well as the opportunities to realize it.

Laxmi Kant Dhakal, Chairperson of the Seed Entrepreneurs Association of Nepal (SEAN) emphasized the importance of private sector engagement and other support areas to strengthen seed production and marketing of open-pollinated varieties and hybrids.

Tara Bahadur Ghimire, Principal Scientist at NARC, gave an overview of the status of NARC varieties, source seed and resource allocation.

Dila Ram Bhandari, former Chief of SQCC, led a discussion around the assumptions and expectations that arose while developing the National Seed Vision.

Technical leads of maize, rice, wheat and vegetables presented a road map on hybrid variety development and seed production in line with the National Seed Vision’s targets for each crop.

“A large quantity of hybrid seeds, worth millions of dollars, is being imported into Nepal each year,” explained AbduRahman Beshir, Seed Systems Lead of CIMMYT’s NSAF project. “However, if stakeholders work together and strengthen the local seed system, there is a huge potential in Nepal not only to become self-sufficient but also to export good quality hybrid seeds in the foreseeable future. Under the NSAF project we are witnessing a few seed companies that have initiated hybrid seed production of maize and tomato.”

In one of the exercises, workshop participants were divided in groups and examined different topics related to the realization of the National Seed Vision. They looked at genetic resources, hybrid and open-pollinated variety development, source seed production and supply, private sector engagement and marketing, seed extension and varietal adoption by farmers, seed quality control services, and roles of research partners and other stakeholders. The groups presented some of the major challenges and opportunities related to these topics, as well as recommendations, which will be documented and shared.

The outcomes of this mid-term review workshop will inform policy and guide the discussions at the upcoming International Seed Conference to be held in early September 2019.

Regulating hybrid seed production

At the workshop, participants thoroughly discussed the draft hybrid seed production and certification guidelines, developed under the NSAF project.

The guidelines are the first of their kind in Nepal and essential to achieve the targets of the National Seed Vision, by engaging the private sector in hybrid seed production.

Hari Kumar Shrestha, CIMMYT’s Seed Systems Officer, and other seed experts from the SQCC presented the main features and regulatory implications of the guidelines.

After the workshop, the guidelines were sent to the National Seed Board for approval.

Happy Seeder can reduce air pollution and greenhouse gas emissions while making profits for farmers

A research paper published in the world’s leading scientific journal, Science Magazine, indicates that using the Happy Seeder agriculture technology to manage rice residue has the potential of generating 6,000-11,500 Indian rupees (about US$85-160) more profits per hectare for the average farmer. The Happy Seeder is a tractor-mounted machine that cuts and lifts rice straw, sows wheat into the soil, and deposits the straw over the sown area as mulch.

The paper “Fields on fire: Alternatives to crop residue burning in India” evaluates the public and private costs and benefits of ten alternate farming practices to manage rice residue, including burn and non-burn options. Happy Seeder-based systems emerge as the most profitable and scalable residue management practice as they are, on average, 10%–20% more profitable than burning. This option also has the largest potential to reduce the environmental footprint of on-farm activities, as it would eliminate air pollution and would reduce greenhouse gas emissions per hectare by more than 78%, relative to all burning options.

This research aims to make the business case for why farmers should adopt no-burn alternative farming practices, discusses barriers to their uptake and solutions to increase their widespread adoption. This work was jointly undertaken by 29 Indian and international researchers from The Nature Conservancy, the International Maize and Wheat Improvement Centre (CIMMYT), the University of Minnesota, the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and other organizations.

Every year, some 23 million tonnes of rice residue is burnt in the states of Haryana, Punjab and Western Uttar Pradesh, contributing significantly to air pollution and short-lived climate pollutants. In Delhi NCR, about half the air pollution on some winter days can be attributed to agricultural fires, when air quality level is 20 times higher than the safe threshold defined by WHO. Residue burning has enormous impacts on human health, soil health, the economy and climate change.

“Despite its drawbacks, a key reason why burning continues in northwest India is the perception that profitable alternatives do not exist. Our analysis demonstrates that the Happy Seeder is a profitable solution that could be scaled up for adoption among the 2.5 million farmers involved in the rice-wheat cropping cycle in northwest India, thereby completely eliminating the need to burn. It can also lower agriculture’s contribution to India’s greenhouse gas emissions, while adding to the goal of doubling farmers income,” says Priya Shyamsundar, Lead Economist at The Nature Conservancy and one of the lead authors of the paper.

“Better practices can help farmers adapt to warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact on agriculture and livelihoods. In addition, India’s efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges,” explains M.L. Jat, CIMMYT cropping systems specialist and a co-author of the study.

“Within one year of our dedicated action using about US$75 million under the Central Sector Scheme on ‘Promotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,’ we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,” said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). “Considering the findings of the Science article as well as reports from thousands of participatory validation trials, our efforts have resulted in an additional direct farmer benefit of US$131 million, compared to a burning option,” explained Mohapatra, who is also secretary of India’s Department of Agricultural Research and Education.

The Government of India subsidy in 2018 for onsite rice residue management has partly addressed a major financial barrier for farmers, which has resulted in an increase in Happy Seeder use. However, other barriers still exist, such as lack of knowledge of profitable no-burn solutions and impacts of burning, uncertainty about new technologies and burning ban implementation, and constraints in the supply-chain and rental markets. The paper states that NGOs, research organizations and universities can support the government in addressing these barriers through farmer communication campaigns, social nudging through trusted networks and demonstration and training. The private sector also has a critical role to play in increasing manufacturing and machinery rentals.

Warmer night temperatures reduce wheat yields in Mexico, scientists say

As many regions worldwide baked under some of the most persistent heatwaves on record, scientists at a major conference in Canada shared data on the impact of spiraling temperatures on wheat.

In the Sonora desert in northwestern Mexico, nighttime temperatures varied 4.4 degrees Celsius between 1981 and 2018, research from the International Maize and Wheat Improvement Center (CIMMYT) shows. Across the world in Siberia, nighttime temperatures rose 2 degrees Celsius between 1988 and 2015, according to Vladimir Shamanin, a professor at Russia’s Omsk State Agrarian University who conducts research with the Kazakhstan-Siberia Network on Spring Wheat Improvement.

“Although field trials across some of the hottest wheat growing environments worldwide have demonstrated that yield losses are in general associated with an increase in average temperatures, minimum temperatures at night — not maximum temperatures — are actually determining the yield loss,” said Gemma Molero, the wheat physiologist at CIMMYT who conducted the research in Sonora, in collaboration with colleague Ivan Ortiz-Monasterio.

“Of the water taken up by the roots, 95% is lost from leaves via transpiration and from this, an average of 12% of the water is lost during the night. One focus of genetic improvement for yield and water-use efficiency for the plant should be to identify traits for adaptation to higher night temperatures,” Molero said, adding that nocturnal transpiration may lead to reductions of up to 50% of available soil moisture in some regions.

Climate challenge

The Intergovernmental Panel on Climate Change (IPCC) reported in October that temperatures may become an average of 1.5 degrees Celsius warmer in the next 11 years. A new IPCC analysis on climate change and land use due for release this week, urges a shift toward reducing meat in diets to help reduce agriculture-related emissions from livestock. Diets could be built around coarse grains, pulses, nuts and seeds instead.

Scientists attending the International Wheat Congress in Saskatoon, the city at the heart of Canada’s western wheat growing province of Saskatchewan, agreed that a major challenge is to develop more nutritious wheat varieties that can produce bigger yields in hotter temperatures.

As a staple crop, wheat provides 20% of all human calories consumed worldwide. It is the main source of protein for 2.5 billion people in the Global South. Crop system modeler Senthold Asseng, a professor at the University of Florida and a member of the International Wheat Yield Partnership, was involved in an extensive study  in China, India, France, Russia and the United States, which demonstrated that for each degree Celsius in temperature increase, yields decline by 6%, putting food security at risk.

Wheat yields in South Asia could be cut in half due to chronically high temperatures, Molero said. Research conducted by the University of New South Wales, published in Environmental Research Letters also demonstrates that changes in climate accounted for 20 to 49% of yield fluctuations in various crops, including spring wheat. Hot and cold temperature extremes, drought and heavy precipitation accounted for 18 to 4% of the variations.

At CIMMYT, wheat breeders advocate a comprehensive approach that combines conventional, physiological and molecular breeding techniques, as well as good crop management practices that can ameliorate heat shocks. New breeding technologies are making use of wheat landraces and wild grass relatives to add stress adaptive traits into modern wheat – innovative approaches that have led to new heat tolerant varieties being grown by farmers in warmer regions of Pakistan, for example.

Collaborative effort

Matthew Reynolds, a distinguished scientist at CIMMYT, is joint founder of the Heat and Drought Wheat Improvement Consortium (HeDWIC), a coalition of hundreds of scientists and stakeholders from over 30 countries.

“HeDWIC is a pre-breeding program that aims to deliver genetically diverse advanced lines through use of shared germplasm and other technologies,” Reynolds said in Saskatoon. “It’s a knowledge-sharing and training mechanism, and a platform to deliver proofs of concept related to new technologies for adapting wheat to a range of heat and drought stress profiles.”

Aims include reaching agreement across borders and institutions on the most promising research areas to achieve climate resilience, arranging trait research into a rational framework, facilitating translational research and developing a bioinformatics cyber-infrastructure, he said, adding that attracting multi-year funding for international collaborations remains a challenge.

Nitrogen traits

Another area of climate research at CIMMYT involves the development of an affordable alternative to the use of nitrogen fertilizers to reduce planet-warming greenhouse gas emissions. In certain plants, a trait known as biological nitrification inhibition (BNI) allows them to suppress the loss of nitrogen from the soil, improving the efficiency of nitrogen uptake and use by themselves and other plants.

Scientists with the BNI research consortium, which includes Japan’s International Research Center for Agricultural Sciences (JIRCAS), propose transferring the BNI trait from those plants to critical food and feed crops, such as wheat, sorghum and Brachiaria range grasses.

“Every year, nearly a fifth of the world’s fertilizer is used to grow wheat, yet the crop only uses about 30% of the nitrogen applied, in terms of biomass and harvested grains,” said Victor Kommerell, program manager for the multi-partner CGIAR Research Programs (CRP) on Wheat and Maize led by the International Maize and Wheat Improvement Center.

“BNI has the potential to turn wheat into a highly nitrogen-efficient crop: farmers could save money on fertilizers, and nitrous oxide emissions from wheat farming could be reduced by 30%.”

Excluding changes in land use such as deforestation, annual greenhouse gas emissions from agriculture each year are equivalent to 11% of all emissions from human activities. About 70% of nitrogen applied to crops in fertilizers is either washed away or becomes nitrous oxide, a greenhouse gas 300 times more potent than carbon dioxide, according to Guntur Subbarao, a principal scientist with JIRCAS.

Although ruminant livestock are responsible for generating roughly half of all agricultural production emissions, BNI offers potential for reducing overall emissions, said Tim Searchinger, senior fellow at the World Resources Institute and technical director of a new report titled “Creating a Sustainable Food Future: A Menu of Solutions to Feed Nearly 10 Billion People by 2050.”

To exploit this roots-based characteristic, breeders would have to breed this trait into plants, said Searchinger, who presented key findings of the report in Saskatoon, adding that governments and research agencies should increase research funding.

Other climate change mitigation efforts must include revitalizing degraded soils, which affect about a quarter of the planet’s cropland, to help boost crop yields. Conservation agriculture techniques involve retaining crop residues on fields instead of burning and clearing. Direct seeding into soil-with-residue and agroforestry also can play a key role.

CRP Maize Annual Report 2018

The newly released CGIAR Research Program on Maize (MAIZE) Annual Report 2018 highlights significant development outcomes and impacts through varietal release, scale-up, delivery and adoption of CIMMYT- and IITA-derived climate-resilient and nutritionally enriched maize varieties.

In 2018, national partners released 81 unique CGIAR-derived maize varieties across Africa, Asia and Latin America. Of these varieties 14 were hybrid combinations, showing that regional and multinational seed companies use MAIZE’s improved germplasm to develop and release improved maize hybrids. 20 of the released varieties are nutritionally enriched — provitamin A, quality protein maize (QPM), high-zinc — the result of the MAIZE partnership with the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH; HarvestPlus).

MAIZE and partners have made great strides in 2018 combatting major pest and disease challenges such as maize lethal necrosis (MLN) and the devastating fall armyworm. MAIZE researchers found that sustainable intensification practices in combination with stress-tolerant maize led to higher yield gains during the El Niño year in Southern Africa. Meanwhile, a crop growth modelling study quantified the impact of climate change on maize and found combined drought and heat stress tolerance has a benefit at least twice that of either one alone.

July 29, 2019, was a remarkable day for Ethiopia. People across the country planted 353,633,660 tree seedlings in just 12 hours, according to the official count, in what is believed to be a world record. This figure also exceeded the target of a nationwide campaign calling citizens to plant 200 million trees in one day. This initiative was part of the Ethiopian government’s “Green Legacy” initiative, which aims to plant 4 billion trees by October.

The International Maize and Wheat Improvement Center (CIMMYT) and other CGIAR centers working in Ethiopia joined the tree-planting campaign. In the morning of July 29, staff members turned out at Adwa park, near Addis Ababa’s Bole International Airport, to plant tree seedlings. This activity was coordinated by the International Livestock Research Institute (ILRI) after receiving an invitation from the Bole subcity administration.

Ethiopia’s tree-planting day received worldwide attention. Al Jazeera reported that, “in addition to ordinary Ethiopians, various international organizations and the business community have joined the tree planting spree which aims to overtake India’s 66 million planting record set in 2017.”

A greener future for CGIAR

Ethiopia’s reforestation efforts align with CGIAR’s sustainability strategy.

In its current business plan, CGIAR has five global challenges including planetary boundaries. Food systems are driving the unsustainable use of the planet’s increasingly fragile ecosystem. A stable climate, water, land, forests and the biodiversity they contain are a precious, yet finite, natural resource.  Food systems account for about one-third of greenhouse gas emissions and will be profoundly affected by its impacts. Agriculture is driving the loss of the world’s forests and productive land, with 5 million hectares of forests lost every year and a third of the world’s land already classified as degraded.  Agriculture accounts for about 70% of water withdrawals globally, is a major cause of water stress in countries where more than 2 billion people live, and water pollution from agricultural systems poses a serious threat to the world’s water systems.

With Ethiopia’s increasing population, there is a high pressure on farmland, unsustainable use of natural resources and deforestation.

At the Agriculture Research for Development Knowledge Share Fair organized in Addis Ababa on May 15, 2019, CGIAR centers demonstrated how they are working together to improve agriculture production and environmental sustainability, tackling local challenges and generating global impact in partnership with other organizations, communities and governments.

At the fair’s opening ceremony, Seleshi Bekele, Ethiopia’s Minister of Water, Irrigation and Electricity, noted that the country has policies, institutional arrangements as well as human and financial resources to work towards sustainability. As a result, Ethiopia has made remarkable achievements towards meeting the Sustainable Development Goals with the continued support and contributions from partners like CGIAR. He also called CGIAR centers to support the efforts to plant 4 billion tree seedlings in 2019, as part of Ethiopia’s climate change adaptation and mitigation goals.
