The development community is introducing increasingly complex and systemic technological designs for sustainable improvements to agriculture. Yet, a systemic perspective is hard to find in “adoption-outcome” focused analyses of technological change processes. In order to improve development interventions, it is necessary not only to analyze both successes and failures, but also the process and impacts of technological change.
Researchers at the International Maize and Wheat Improvement Center (CIMMYT) and the Institute of Development Studies (IDS) recently published a paper on rethinking technological change in smallholder agriculture, arguing against the conventional approach to studying technology adoption.
The problem with the concept of technology adoption
While the adoption rate of newly introduced technologies is still used in the evaluation of agricultural research and development, the theory of technology adoption is an insufficient framework for understanding technological change. It is too linear, too binary, too focused on individual decisions and gives an inaccurate and misleading picture to researchers.
The theory of adoption treats technology like a âblack boxâ that is transferred smoothly from one setting to another, following a linear progression of old and inferior tools and methods to new improved ones. This theory is too simplistic to align with the complex realities of the capabilities and agency of multiple actors. In addition, in cases of participatory technology development, where intended users are involved in the creation of innovations, adoption rates are often limited due to the relatively small scale of the project.
Using adoption rate as the only indicator of success or failure can lead researchers to ignore wider impacts of the introduction of a new technology. Adoption rates could go up, but use of a new technology could cause harm to social relations, the local environment, or its resilience. Low adoption rates could classify a program as a failure, while farmers benefited substantially in undetected ways, for example forming networks or acquiring new skills and knowledge. A singular focus on adoption rates thus limits our understanding of what happens in processes of technological change.

An alternative conceptual framework
In addition to the introduction of a new technology to small-scale farming systems, technological change involves the agency of many social actors. The agency of farmers, scientists, project managers and extension officers is key to understand whether a new technology is perceived to be useful, accessible or realistic, as well as how it is adjusted and changing social relations.
A new framework is needed to capture this reconfiguration of social and technological components that result from the introduction of a new technology to a community.
The authors of this paper propose an alternative conceptual framework with an agent-, practice- and process-oriented approach to better understand technological change. The framework is composed of four key components: propositions, encounters, dispositions and responses.
Propositions are composed of artefacts, methods, techniques and practices and a proposed mode of engagement in agricultural production. Encounters can be deliberately organized, for example a field day, or spontaneous, when a farmer sees a neighbor using a new tool. Intended users of technology may be disposed to respond in a variety of different ways, and dispositions may change over time. Finally, responses are a process or pathway that is likely to involve adjustment or recalibration to make the new technology work for the farmer.
Further work to operationalize this framework is needed. The authors suggest a next step of developing indicators to measure learning, experimentation and behavioral change as part of analyzing technological change processes.

For a number of reasons, including limited interdisciplinary collaboration and a dearth of funding, revolutionary new plant research findings are not being used to improve crops.
âTranslational researchâ â efforts to convert basic research knowledge about plants into practical applications in crop improvement â represents a necessary link between the world of fundamental discovery and farmers’ fields. This kind of research is often seen as more complicated and time consuming than basic research and less sexy than working at the âcutting edgeâ where research is typically divorced from agricultural realities in order to achieve faster and cleaner results; however, modern tools â such as genomics, marker-assisted breeding, high throughput phenotyping of crop traits using drones, and speed breeding techniques â are making it both faster and cost-effective.
In a new article in Crop Breeding, Genetics, and Genomics, wheat physiologist Matthew Reynolds of the International Maize and Wheat Improvement Center (CIMMYT) and co-authors make the case for increasing not only funding for translational research, but the underlying prerequisites: international and interdisciplinary collaboration towards focused objectives and a visionary approach by funding organizations.
âItâs ironic,â said Reynolds. âMany breeding programs have invested in the exact technologies â such as phenomics, genomics and informatics â that can be powerful tools for translational research to make real improvements in yield and adaptation to climate, disease and pest stresses. But funding to integrate these tools in front-line breeding is quite scarce, so they arenât reaching their potential value for crop improvement.â
Members of the International Wheat Yield Partnership (IWYP) which focuses on translational research to boost wheat yields.
Many research findings are tested for their implications for wheat improvement by the International Wheat Yield Partnership (IWYP) at the IWYP Hub, a centralized technical platform for evaluating innovations and building them into elite wheat varieties, co-managed by CIMMYT at its experimental station in Obregon, Mexico.
IWYP has its roots with the CGIAR Research Program on Wheat (WHEAT), which in 2010 formalized the need to boost both wheat yield potential as well as its adaptation to heat and drought stress. The network specializes in translational research, harnessing scientific findings from around the world to boost genetic gains in wheat, and capitalizing on the research and pre-breeding outputs of WHEAT and the testing networks of the International Wheat Improvement Network (IWIN). These efforts also led to the establishment of the Heat and Drought Wheat Improvement Consortium (HeDWIC).
âWeâve made extraordinary advances in understanding the genetic basis of important traits,â said IWYPâs Richard Flavell, a co-author of the article. âBut if they arenât translated into crop production, their societal value is lost.â
The authors, all of whom have proven track records in both science and practical crop improvement, offer examples where exactly this combination of factors led to the impactful application of innovative research findings.
Improving the Vitamin A content of maize: A variety of maize with high Vitamin A content has the potential to reduce a deficiency that can cause blindness and a compromised immune system. This development happened as a result of many translational research efforts, including marker-assisted selection for a favorable allele, using DNA extracted from seed of numerous segregating breeding crosses prior to planting, and even findings from gerbil, piglet and chicken models â as well as long-term, community-based, placebo-controlled trials with children â that helped establish that Vitamin A maize is bioavailable and bioefficacious.
Flood-tolerant rice: Weather variability due to climate change effects is predicted to include both droughts and floods. Developing rice varieties that can withstand submergence in water due to flooding is an important outcome of translational research which has resulted in important gains for rice agriculture. In this case, the genetic trait for flood tolerance was recognized, but it took a long time to incorporate the trait into elite germplasm breeding programs. In fact, the development of flooding tolerant rice based on a specific SUB 1A allele took over 50 years at the International Rice Research Institute in the Philippines (1960â2010), together with expert molecular analyses by others. The translation program to achieve efficient incorporation into elite high yielding cultivars also required detailed research using molecular marker technologies that were not available at the time when trait introgression started.
Other successes include new approaches for improving the yield potential of spring wheat and the discovery of traits that increase the climate resilience of maize and sorghum.
One way researchers apply academic research to field impact is through phenotyping. Involving the use of cutting edge technologies and tools to measure detailed and hard to recognize plant traits, this area of research has undergone a revolution in the past decade, thanks to more affordable digital measuring tools such as cameras and sensors and more powerful and accessible computing power and accessibility.
Scientists are now able to identify at a detailed scale plant traits that show how efficiently a plant is using the sunâs radiation for growth, how deep its roots are growing to collect water, and more â helping breeders select the best lines to cross and develop.

Phenotyping is key to understanding the physiological and genetic bases of plant growth and adaptation and has wide application in crop improvement programs. Recording trait data through sophisticated non-invasive imaging, spectroscopy, image analysis, robotics, high-performance computing facilities and phenomics databases allows scientists to collect information about traits such as plant development, architecture, plant photosynthesis, growth or biomass productivity from hundreds to thousands of plants in a single day. This revolution was the subject of discussion at a 2016 gathering of more than 200 participants at the International Plant Phenotyping Symposium hosted by CIMMYT in Mexico and documented in a special issue of Plant Science.
There is currently an explosion in plant science. Scientists have uncovered the genetic basis of many traits, identified genetic markers to track them and developed ways to measure them in breeding programs. But most of these new findings and ideas have yet to be tested and used in breeding programs, wasting their potentially enormous societal value.
Establishing systems for generating and testing new hypotheses in agriculturally relevant systems must become a priority, Reynolds states in the article. However, for success, this will require interdisciplinary, and often international, collaboration to enable established breeding programs to retool. Most importantly, scientists and funding organizations alike must factor in the long-term benefits as well as the risks of not taking timely action. Translating a research finding into an improved crop that can save lives takes time and commitment. With these two prerequisites, basic plant research can and should positively impact food security.

Ensuring the access of small-scale farmers to products and potential benefits from genetic engineering (GE) technologies for agriculture will require concerted investment and research by public institutions worldwide and particularly in low- and middle-income countries.
This was a key conclusion of a new review paper describing cutting-edge GE applications that offer exciting options to enhance the disease and pest resistance of important food crops and the ecological sustainability of cropping systems.
The technologies include gene editing (site-specific changes to DNA in a genome), gene drives (greatly enhancing or reducing frequency of genes that affect insect or pathogen reproduction), and synthetic biology (re-design or construction of biological devices, for example chromosomes or organelles).
Authored by international experts in policy, socioeconomics, and biological science, the new paper outlines potential uses of the technologies, particularly to address problems that affect resource-poor farmers or consumers, such as the viruses that attack cassava, the Striga weed that is a parasite of maize, or the fungal pathogen of groundnut that produces deadly toxins.
A weak capacity for research and development in many countries, combined with a small and declining public investment, raises questions about those nationsâ ability to develop and deliver high-quality GE technologies or realize their benefits.
âThe concern is that farmers not served by leading companies, who are developing the technologies, will be unable to obtain new, resistant crop varieties or other products of these technologies,â said Kevin Pixley, director of the genetic resources program of the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new paper.
The technologies have already proven effective for controlling bacterial, fungal, and viral plant pathogens, as well as insects that transmit them. For example, GE approaches to control cassava brown streak disease and cassava bacterial blightâfor which there are few or no known sources of resistance in cassava itselfâappear on track to produce resistant versions of cassava.
Future gene drive technologies that can be kept within specific areas and reversed if needed may offer ways to control insects that carry plant diseases or weeds that damage crops, and synthetic biology could someday create plants that are immune to invading viruses.

Many countries are still deciding whether and how they will regulate new GE products. The new paper explains how key factors including the cost and complexity of complying with biosafety regulations will shape the potential distribution of the technologies and products, determining which institutions undertake the related research and, as a result, which traits and crops are studied.
Civil society concerns regarding GE technologies and how or by whom they are deployed add important considerations to the complex questions surrounding the use of GE products.
âRealizing the potential of GE crops will require investments and policies for research, intellectual property regimes, and regulatory frameworks,â say the authors, âand societies must also address legitimate concerns about their responsible stewardship, agroecological sustainability, and equitable access to associated benefits.â

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 â the wheat used for pasta â 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.
“Weâve 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 wheatâs 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 natureâs 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 wheatâs 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 â the ability to maintain high yields over time under varying conditions.
The successful, large-scale use of genes from wheatâs wild relatives has helped broaden the genetic diversity of modern, improved bread wheat nearly to the level of the cropâs 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.

Wheat is Afghanistanâs number-one staple crop, but the country does not grow enough and must import millions of tons of grain each year to satisfy domestic demand.
Despite the severe social and political unrest that constrain agriculture in Afghanistan, many farmers are growing high-yielding, disease resistant varieties developed through international, science-based breeding and made available to farmers as part of partnerships with national wheat experts and seed producers.
These and other findings have emerged from the first-ever large-scale use of DNA fingerprinting to assess Afghanistan farmersâ adoption of improved wheat varieties, which are replacing less productive local varieties and landraces, according to a paper published yesterday in the science journal BMC Genomics.
The study is part of an activity supported between 2003 and 2018 by the Australian Department of Foreign Affairs and Trade, through which the Agricultural Research Institute of Afghanistan and the International Maize and Wheat Improvement Center (CIMMYT) introduced, tested, and released improved wheat varieties.
“As part of our study, we established an extensive ‘reference library’ of released varieties, elite breeding lines, and Afghan wheat landraces,” said Susanne Dreisigacker, wheat molecular breeder at CIMMYT and lead author of the new paper.
“We then compared wheat collected on farmersâ fields with the reference library. Of the 560 wheat samples collected in 4 provinces during 2015-16, farmers misidentified more than 40%, saying they were of a different variety from that which our DNA analyses later identified.”
Wheat is the most important staple crop in Afghanistan â more than 20 million of the countryâs rural inhabitants depend on it â but wheat production is unstable and Afghanistan has been importing between 2 and 3 million tons of grain each year to meet demand.
Over half of the population lives below the poverty line, with high rates of malnutrition. A key development aim in Afghanistan is to foster improved agronomic practices and the use of high quality seed of improved wheat varieties, which together can raise yields by over 50%.
“Fungal diseases, particularly yellow rust and stem rust, pose grave threats to wheat in the country,” said Eric Huttner, research program manager for crops at the Australian Centre for International Agricultural Research (ACIAR) and co-author of the present paper. “It’s crucial to know which wheat varieties are being grown where, in order to replace the susceptible ones with high-performing, disease resistant varieties.”
Varietal adoption studies typically rely on questionnaires completed by breeders, extension services, seed producers, seed suppliers, and farmers, but such surveys are complicated, expensive, and often inaccurate.
“DNA fingerprinting resolves uncertainties regarding adoption and improves related socioeconomic research and farm policies,” Huttner explained, adding that for plant breeding this technology has been used mostly to protect intellectual property, such as registered breeding lines and varieties in more developed economies.
This new study was commissioned by ACIAR as a response to a request from the Government of Afghanistan for assistance in characterizing the Afghan wheat gene bank, according to Huttner.
“This provided the reference library against which farmers’ samples could be compared,” he explained. “Accurately identifying the varieties that farmers grow is key evidence on the impact of introducing improved varieties and will shape our future research
Joint research and development efforts involving CIMMYT, ACIAR, the Food and Agriculture Organization (FAO) of the United Nations, the International Centre of Agricultural Research in Dry Areas (ICARDA), French Cooperation, and Afghanistan’s Ministry of Agriculture, Irrigation and Livestock (MAIL) and Agricultural Research Institute (ARIA) have introduced more than 400 modern, disease-resistant wheat varieties over the last two decades. Nearly 75% of the wheat grown in the areas surveyed for this study comes from these improved varieties.
“New sequencing technologies are increasingly affordable and their cost will continue to fall,” said Dreisigacker. “Expanded use of DNA fingerprinting can easily and accurately identify the wheat cultivars in farmers’ fields, thus helping to target breeding, agronomy, and development efforts for better food security and farmer livelihoods.”

A diverse group of agriculture, food security, environment and science journalists gathered in Saskatoon, Canada recently for an intensive course in innovative wheat research, interviews with top international scientists and networking with peers.
The occasion was the International Wheat Congress (IWC), which convened more than 900 wheat scientists and researchers in Saskatoon, in Canadaâs biggest wheat-growing province, Saskatchewan, to discuss their latest work to boost wheat productivity, resilience and nutrition.

The seven journalists were part of a group of 11 who won a competitive sponsorship offered by the CGIAR Research Program on Wheat (WHEAT). Seven journalists attended the conference, while another four followed the proceedings and activities from home. The ten-day immersive training included multiple daily press briefings with top scientists in climate change modeling and resilience testing, innovative breeding techniques, analysis and protection of wheat diversity and many more topics, on top of a full schedule of scientific presentations.
âThe scientists were so eager to talk to us, and patient with our many questions,â said Nkechi Isaac, from the Leadership newspaper group in Nigeria. âEven the director general of [the International Maize and Wheat Improvement Center] CIMMYT spoke with us for almost an hour.â
âIt was a pleasant surprise for me.â
The journalists, who come from regions as diverse as sub-Saharan Africa and East Asia, offered support and encouragement from their travel preparations though their time in Saskatoon and beyond â sharing story ideas, interview and site visit opportunities, news clips and photos through a WhatsApp group.

âIt is really helpful to be connected to colleagues around the world,â said Amit Bhattacharya of the Times of India. âI know we will continue to be a resource and network for each other through our careers.â
The week wasnât all interviews and note-taking. The journalists were able to experience Saskatchewan culture, from a tour of a wheat quality lab and a First Nations dance performance to a visit to a local wheat farm, and even an opportunity to see Saskatoonâs newest modern art gallery.
The media sponsorship at IWC aimed to encourage informed coverage of the importance of wheat research, especially for farmers and consumers in the Global South, where wheat is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 a day.
The group also spoke with members of the many coalitions that facilitate the collaboration that makes innovative wheat research possible, including the International Wheat Yield Partnership (IWYP), the Heat and Drought Wheat Improvement Consortium (HeDWIC) and the G20-organized Wheat Initiative.
âThis is the first time weâve invested this heavily in journalist training,â said WHEAT program director Hans Braun. âWe think the benefits â for the journalists, who gained a greater understanding of wheat research issues, and for developing country audiences, who will be more aware of the importance of improving wheat ââ are worth it.â

A roundtable discussion with peers from Canadian news organizations and seasoned science communications professionals and a networking breakfast with CIMMYT scientists provided platforms for a candid exchange on the challenges and opportunities in communicating wheat science in the media.
A common refrain was the importance of building relationships between scientists and media professionals â because wheat science offers dramatic stories for news audiences, and an informed and interested public can in turn lead to greater public investment in wheat science. The journalists and scientists in Saskatoon have laid a solid foundation for these relationships.

The Regional Drought Monitoring and Outlook System is the product of an ICIMOD-CIMMYT partnership through the United States Agency for International Development (USAID) and the National Aeronautics and Space Administration (NASA) supported SERVIR Hindu Kush Himalaya (HKH) programme, in collaboration with Climate Service for Resilient Development (CSRD), led by ICIMOD and CIMMYT, respectively.
âCommonly associated with epic flooding, particularly in the enormous breadbasket region known as the Indo-Gangetic Plains that extends across Pakistan, India, southern Nepal, and Bangladesh, the region also faces droughts driven by rising temperatures and erratic rainfall and which threaten crops, food security, and livelihoods,â said Faisal Mueen Qamer, Remote Sensing Specialist of ICIMOD, which helped develop the system and organize the workshop.
âWe expect the system to foster resilience in South Asian agriculture, while supporting future institutional frameworks and policies for farm compensation and adaptation, through decision makersâ access to timely and action-oriented information,â Qamar explained.
With a growing population of 1.6 billion people, South Asia hosts 40% of the worldâs poor and malnourished on just 2.4% of its land. A 2010 study found a linear drop of 7.5% in rainfall in South Asia from 1900 to 2005.
âShrinking glaciers, water scarcity, rising sea levels, shifting monsoon patterns, and heat waves place considerable stress on South Asian countries, whose primary employment sector remains agriculture,â said Mohammad Faisal, Director General for South Asia at Pakistan’s Ministry of Foreign Affairs, during the workshop opening.

Raising awareness about drought and its mitigation
Twenty-three participants from six South Asia countries plus five expert instructors attended the workshop, which offered presentations and hands-on training on a suite of applications and associated data analysis tools, including the South Asian Land Data Assimilation System (SALDAS), the Regional Drought Explorer, and the National Drought Early Warning System.
Muhammad Azeem Khan, Member of the Food Security & Climate Change at the Planning Commission of Pakistan, said the scale of present and future climate challenges is clearly evident.
âIn Pakistan, we regularly see parts of the country in the grip of severe drought, while others have flash floods,â Khan commented during the workshop closing, while commending its organizers. âFrequent drought diminishes agricultural production and food security, especially for people in rural areas. Effectively managing the impacts of climate change requires a response that builds and sustains South Asiaâs social, economic, and environmental resilience, as well as our emergency response capacity.â
Through CSRD, a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries, CIMMYT helped extend the Regional Drought Monitoring and Outlook System to Bangladesh, from its original coverage of Afghanistan, Nepal, and Pakistan.
âTranslating complex climate information into easy-to-understand and actionable formats is core to CSRDâs mission and helps spread awareness about climate challenges,â said Tim Krupnik, CIMMYT cropping systems agronomist based in Bangladesh. âThis consortium provides strength and technical expertise to develop relevant climate products, including decision-support information for farmers and other stakeholders, thus fostering resilience to climate-related risks.â

A research paper published in the worldâs 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 âFields on fire: Alternatives to crop residue burning in Indiaâ 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%â20% 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.

âDespite 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 agricultureâs contribution to Indiaâs greenhouse gas emissions, while adding to the goal of doubling farmers income,â says Priya Shyamsundar, Lead Economist at The Nature Conservancy and one of the lead authors of the paper.
âBetter 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, Indiaâs efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges,â explains M.L. Jat, CIMMYT cropping systems specialist and a co-author of the study.

âWithin one year of our dedicated action using about US$75 million under the Central Sector Scheme on âPromotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,â we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,â said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). âConsidering 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,â explained Mohapatra, who is also secretary of Indiaâs 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.
This research was supported by the Susan and Craig McCaw Foundation, the Institute on the Environment at the University of Minnesota, the CGIAR Research Program on Wheat (WHEAT), and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). The Happy Seeder was originally developed through a project from the Australian Centre for International Agricultural Research (ACIAR).

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 Russiaâs Omsk State Agrarian University who conducts research with the Kazakhstan-Siberia Network on Spring Wheat Improvement.
âAlthough 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 â not maximum temperatures â are actually determining the yield loss,â said Gemma Molero, the wheat physiologist at CIMMYT who conducted the research in Sonora, in collaboration with colleague Ivan Ortiz-Monasterio.
âOf 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,â 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 Canadaâs 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 â 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.
âHeDWIC is a pre-breeding program that aims to deliver genetically diverse advanced lines through use of shared germplasm and other technologies,â Reynolds said in Saskatoon. âItâs 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.â
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.

âEvery year, nearly a fifth of the worldâs fertilizer is used to grow wheat, yet the crop only uses about 30% of the nitrogen applied, in terms of biomass and harvested grains,â 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.
âBNI 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%.â
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 âCreating a Sustainable Food Future: A Menu of Solutions to Feed Nearly 10 Billion People by 2050.â
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 planetâs 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.

A new economic study in the journal Science shows that thousands of farmers in northern India could increase their profits if they stop burning their rice straw and adopt no-till practices to grow wheat. Alternative farming practices could also cut farmersâ greenhouse gas emissions from on-farm activities by as much as 78% and help lower air pollution in cities like New Delhi.
The new study compares the costs and benefits of 10 distinct land preparation and sowing practices for northern Indiaâs rice-wheat cropping rotations, which are spread across more than 4 million hectares. The direct seeding of wheat into unplowed soil and shredded rice residues was the best option â it raises farmersâ profits through higher yields and savings in labor, fuel, and machinery costs.
The study, conducted by a global team of eminent agriculture and environmental scientists, was led by researchers from The Nature Conservancy, the International Maize and Wheat Improvement Center (CIMMYT), the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and the University of Minnesota.
A burning issue
To quickly and cheaply clear their fields to sow wheat each year, farmers in northern India burn an estimated 23 million tons of straw from their rice harvests. That enormous mass of straw, if packed into 20-kilogram 38-centimeter-high bales and piled on top of each other, would reach a height of over 430,000 kilometers â about 1.1 times the distance to the moon.
Regulations are in place in India to reduce agricultural fires but burning continues because of implementation challenges and lack of clarity about the profitability of alternate, no-burn farming.
Farmers have alternatives, the study shows. To sow wheat directly without plowing or burning rice straw, farmers need to purchase or rent a tractor-mounted implement known as the âHappy Seeder,â as well as attach straw shedders to their rice harvesters. Leaving straw on the soil as a mulch helps capture and retain moisture and also improves soil quality, according to M.L. Jat, CIMMYT Principal Scientist, cropping systems specialist and a co-author of the study.

Win-win
The Science study demonstrates that it is possible to reduce air pollution and greenhouse gas emissions in a way that is profitable to farmers and scalable.
The paper shows that Happy Seeder-based systems are on average 10%â20% more profitable than straw burning options.
âOur study dovetails with 2018 policies put in place by the government of India to stop farmers from burning, which includes a US$166 million subsidy to promote mechanization to manage crop residues within fields,â said Priya Shyamsundar, Lead Economist, Global Science, of The Nature Conservancy and first author of the study.
Shyamsundar noted that relatively few Indian farmers currently sow their wheat using the Happy Seeder but manufacturing of the Seeder had increased in recent years. âLess than a quarter of the total subsidy would pay for widespread adoption of the Happy Seeder, if aided by government and NGO support to build farmer awareness and impede burning.â
“With a rising population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land,â said Jat, who recently received Indiaâs prestigious Rafi Ahmed Kidwai Award for outstanding and impact-oriented research contributions in natural resource management and agricultural engineering. âBetter 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, Indiaâs efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges.â
In November 2017, more than 4,000 schools closed in Delhi due to seasonal smog. This smog increases during October and November when fields are burned. It causes major transportation disruptions and poses health risks across northern India, including Delhi, a city of more than 18 million people.
Some of these problems can be resolved by the use of direct sowing technologies in northwestern India.
âWithin one year of our dedicated action using about US$75 million under the Central Sector Scheme on âPromotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,â we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,â said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). âConsidering 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,â explained Mohapatra, who is also secretary of Indiaâs Department of Agricultural Research and Education.
This research was supported by the Susan and Craig McCaw Foundation, the Institute on the Environment at the University of Minnesota, the CGIAR Research Program on Wheat (WHEAT), and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). The Happy Seeder was originally developed through a project from the Australian Centre for International Agricultural Research (ACIAR).

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 â provitamin A, quality protein maize (QPM), high-zinc â 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.
The newly released CGIAR Research Program on Wheat (WHEAT) Annual Report 2018 highlights joint achievements that are making an invaluable contribution to global food security, especially for the 2.5 billion people who depend on wheat for their livelihoods.
The report describes work with national and global partners using state of the art technology to measure traits and performance for faster development of high-yielding, heat- and drought-tolerant varieties; rapidly diagnosing diseases in farmersâ fields; supporting gender equality in agricultural innovations, and much more.
With its national partners, WHEAT released 48 new CGIAR-derived wheat varieties to farmers in 2018, and developed 11 innovations related to farm management practices or social sciences.
The International Maize and Wheat Improvement Center (CIMMYT) is offering a new set of improved maize hybrids to partners in South and South East Asia and similar agro-ecological zones, to scale up production for farmers in these areas.

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 governmentâs âGreen Legacyâ 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 Ababaâs 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.
Ethiopiaâs tree-planting day received worldwide attention. Al Jazeera reported that, âin 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.â

A greener future for CGIAR
Ethiopiaâs reforestation efforts align with CGIARâs sustainability strategy.
In its current business plan, CGIAR has five global challenges including planetary boundaries. Food systems are driving the unsustainable use of the planetâs 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 worldâs forests and productive land, with 5 million hectares of forests lost every year and a third of the worldâs 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 worldâs water systems.
With Ethiopiaâs 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 fairâs opening ceremony, Seleshi Bekele, Ethiopiaâs 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 Ethiopiaâs climate change adaptation and mitigation goals.

In this episode, we talk to Juan Gonzalo Jaramillo Mejia, Project Manager and Researcher on Inclusion Innovation and Social Protection. He discusses why we must engage men in the fight for gender equality and how using a social inclusion lens to social protection programs is necessary to ensure that no one is left behind.
