In the midst of Ethiopia’s exponential population climb and the strikes of the climate emergency with erratic rains, dry spells, sharp floods and failed crops, the country launched a digital agro-climate advisory platform, called EDACaP, to put resilience at the center of agricultural livelihoods.
A team effort led by the Ethiopian Institute of Agricultural Research (EIAR) in partnership with the Ministry of Agriculture (MoA) and the National Meteorological Agency (NMA), alongside numerous research centers and programs: the International Center for Tropical Agriculture (CIAT), the International Maize and Wheat Improvement Center (CIMMYT), the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the International Research Institute for Climate and Society (IRI), with support from the Agricultural Growth Program (AGP), the EDACaP has come to life.
In this era of climate emergency, what is left when traditional knowledge is no longer enough?

TEXCOCO, Mexico â Using field and mobile phone surveillance data together with forecasts for spore dispersal and environmental suitability for disease, an international team of scientists has developed an early warning system which can predict wheat rust diseases in Ethiopia. The cross-disciplinary project draws on expertise from biology, meteorology, agronomy, computer science and telecommunications.
Reported this week in Environmental Research Letters, the new early warning system, the first of its kind to be implemented in a developing country, will allow policy makers and farmers all over Ethiopia to gauge the current situation and forecast wheat rust up to a week in advance.
The system was developed by the University of Cambridge, the UK Met Office, the Ethiopian Institute of Agricultural Research (EIAR), the Ethiopian Agricultural Transformation Agency (ATA) and the International Maize and Wheat Improvement Center (CIMMYT). It works by taking near real-time information from wheat rust surveys carried out by EIAR, regional research centers and CIMMYT using a smartphone app called Open Data Kit (ODK).
This is complemented by crowd-sourced information from the ATA-managed Farmersâ Hotline. The University of Cambridge and the UK Met Office then provide automated 7-day advance forecast models for wheat rust spore dispersal and environmental suitability based on disease presence.
All of this information is fed into an early warning unit that receives updates automatically on a daily basis. An advisory report is sent out every week to development agents and national authorities. The information also gets passed on to researchers and farmers.

Timely alerts
âIf thereâs a high risk of wheat rust developing, farmers will get a targeted SMS text alert from the Farmersâ Hotline. This gives the farmer about three weeks to take action,â explained Dave Hodson, principal scientist with CIMMYT and co-author of the research study. The Farmersâ Hotline now has over four million registered farmers and extension agents, enabling rapid information dissemination throughout Ethiopia.
Ethiopia is the largest wheat producer in sub-Saharan Africa but the country still spends in excess of $600 million annually on wheat imports. More can be grown at home and the Ethiopian government has targeted to achieve wheat self-sufficiency by 2023.
âRust diseases are a grave threat to wheat production in Ethiopia. The timely information from this new system will help us protect farmersâ yields, and reach our goal of wheat self-sufficiency,â said EIAR Director Mandefro Nigussie.
Wheat rusts are fungal diseases that can be dispersed by wind over long distances, quickly causing devastating epidemics which can dramatically reduce wheat yields. Just one outbreak in 2010 affected 30% of Ethiopiaâs wheat growing area and reduced production by 15-20%.
The pathogens that cause rust diseases are continually evolving and changing over time, making them difficult to control. âNew strains of wheat rust are appearing all the time â a bit like the flu virus,â explained Hodson.
In the absence of resistant varieties, one solution to wheat rust is to apply fungicide, but the Ethiopian government has limited supplies. The early warning system will help to prioritize areas at highest risk of the disease, so that the allocation of fungicides can be optimized.

The cream of the crop
The early warning system puts Ethiopia at the forefront of early warning systems for wheat rust. âNowhere else in the world really has this type of system. Itâs fantastic that Ethiopia is leading the way on this,â said Hodson. âItâs world-class science from the UK being applied to real-world problems.â
âThis is an ideal example of how it is possible to integrate fundamental research in modelling from epidemiology and meteorology with field-based observation of disease to produce an early warning system for a major crop,â said Christopher Gilligan, head of the Epidemiology and Modelling Group at the University of Cambridge and a co-author of the paper, adding that the approach could be adopted in other countries and for other crops.
âThe development of the early warning system was successful because of the great collaborative spirit between all the project partners,â said article co-author Clare Sader-Allen, currently a regional climate modeller at the British Antarctic Survey.
âClear communication was vital for bringing together the expertise from a diversity of subjects to deliver a common goal: to produce a wheat rust forecast relevant for both policy makers and farmers alike.â
This study was made possible through the support provided by the BBSRC GCRF Foundation Awards for Global Agriculture and Food Systems Research, which brings top class UK science to developing countries, the Delivering Genetic Gains in Wheat (DGGW) Project managed by Cornell University and funded by the Bill & Melinda Gates Foundation and the UK Department for International Development (DFID). The Government of Ethiopia also provided direct support into the early warning system. This research is supported by CGIAR Fund Donors.

ABOUT THE ETHIOPIAN INSTITUTE OF AGRICULTURAL RESEARCH (EIAR):
The Ethiopian Institute of Agricultural Research (EIAR) is one of the oldest and largest agricultural research institutes in Africa, with roots in the Ethiopian Agricultural Research System (EARS), founded in the late 1940s. EIARâs objectives are: (1) to generate, develop and adapt agricultural technologies that focus on the needs of the overall agricultural development and its beneficiaries; (2) to coordinate technically the research activities of Ethiopian Agricultural Research System; (3) build up a research capacity and establish a system that will make agricultural research efficient, effective and based on development needs; and (4) popularize agricultural research results. EIARâs vision is to see improved livelihood of all Ethiopians engaged in agriculture, agro-pastoralism and pastoralism through market competitive agricultural technologies.

One major reason why maize productivity in sub-Saharan Africa is very low is poor soil health. Soil acidity is often mentioned because of its impact on crop yields and the extent of acid soils in the region. A recent soil mapping exercise, conducted by the Ethiopian Soil Information System (EthioSIS) under the administration of the Ethiopian Agricultural Transformation Agency (ATA), estimated that 43% of arable lands were affected by acid soils and that 3.6 million people, about 10% of the total rural population, live in areas with acidic soils.
Very acid soils â those with a pH below 5.5, roughly one hundred times more acidic than neutral soils â are associated with certain toxicities, like aluminum and iron excess, and some nutrient deficiencies. Soil acidity pushes soil nutrients out of reach of the plant, leading to stunting of root system and plant. As a result, the plant becomes also less tolerant to drought.
Soil acidification depends on soil nature, agroecology and farming systems. It happens through natural leaching of CO2 after rainfall and excess application of nitrogenous fertilizer or organic matter, for instance.
As a result, soil acidity significantly affects maize yields. In Ethiopia, studies have revealed substantial impacts on crop productivity related to acid soils and the importance of acid soil management for Ethiopiaâs food security. The Ethiopian Institute of Agricultural Research (EIAR) estimated that soil acidity on wheat production alone costed the country over 9 billion Ethiopian Birr, about $300 million per year.
Acidic soils in the limelight
Preliminary analysis led by the International Food Policy Research Institute (IFPRI) suggests that yields of major cereal crops, such as wheat and barley, could increase by 20 to 40% with the application of lime in acidic areas of the country.
While these preliminary results are significant, we need to know more about local farmersâ experience with acidic soil and their mitigation strategies. Such impact assessments are however typically determined at either the national or experimental plot level and do not map where mitigating against acid soils would be the most profitable.
To improve acid soils, farmers may apply lime on their fields to raise the pH, a practice known as liming. How much lime to apply will depend on the crop, soil type but also on the quality of lime available. Liming has multiple beneficial effects like improving nitrogen fixation of legume nodules, boosting yields of legume crops.
But liming has a cost. It can quickly become a very bulky affair as we need to apply 3 to 4 tons per hectare for sandy soils and up to 8 tons per hectare for clay and humifere soils.
Furthermore, existing lime markets are quite limited or even non-existent in many areas, even those where acidic soils are prevalent. Developing supply chains from scratch is difficult and costly. Understanding the costs and potential returns to such investments is important. There are many questions to ask at different levels, from the farm and farming system to the lime supply chain. What are the available lime sources â calcitic, dolomite or blend â and lime quality? Where are the lime processing units and how could you assess the transport cost to the farms? What could be the crop yield response depending on the lime application?
User-friendly and scalable dashboard
IFPRI, in collaboration with EIAR, the International Maize and Wheat Improvement Center (CIMMYT) and the German aid agency GIZ, developed a pilot in Ethiopiaâs Amhara region to help better target lime interventions for a greater impact. Amhara region was chosen because of the importance of acid soils, and access to extensive soil data.
Combination of several spatial datasets on soil quality, agroecological, weather, long-term agronomic trials and crop modelling tools enabled to generate at scale, georeferenced estimates of crop yield responses for different lime applications. Calibration of this spatial model for wheat estimated a yield increase of approximately 30% increasing the pH from 5.5 to 6.5, which is relatively consistent with general research data and expert opinion.
Mapped estimates of the grain prices and the delivered costs of lime, based on the location of the lime crushers in the region and transport costs, enables then to map out the spatial profitability of lime operations.
Initial calculations revealed a great variability of lime costs at the farmgate, with transportation representing at least half of total lime costs. It showed also that farmers often do not use the most cost-effective combination of inputs to tackle soil acidity.
Another possible application is to determine maize growing areas where lime benefits outweigh the costs, which would be ideal sites for demonstrating to farmers the positive impact lime applications could have to their livelihoods.
This Amhara lime dashboard prototype demonstrated its scalability. A national dashboard is currently being developed, which includes lime sources GPS location, grain prices and district-level soil quality mapping. This approach is tested also in Tanzania.
CIMMYT and its partners plan to package such tool in a user-friendly open-access web version that can be rapidly updated and customized depending on the area of intervention, for instance integrating a new lime source, and applied for different crops, and across the Eastern African region. Such dashboards will help development organizations and government make better informed decisions regarding lime investments.
New research shows that smallholder farmers in Ethiopia used various coping mechanisms apart from fungicides in response to the recent wheat rust epidemics in the country. Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Ethiopian Institute of Agricultural Research (EIAR) call for continuous support to research and extension programs to develop and disseminate improved wheat varieties with resistant traits to old and newly emerging rust races.
Rising wheat yields cannot catch up rising demand
Wheat is the fourth largest food crop in Ethiopia cultivated by smallholders, after teff, maize and sorghum. Ethiopia is the largest wheat producer in sub-Saharan Africa and average farm yields have more than doubled in the past two decades, reaching 2.74 tons per hectare on average in 2017/18. Farmers who use improved wheat varieties together with recommended agronomic practices recorded 4 to 6 tons per hectare in high-potential wheat growing areas such as the Arsi and Bale zones. Yet the country remains a net importer because demand for wheat is rapidly rising.
The Ethiopian government has targeted wheat self-sufficiency by 2023 and the country has huge production potential due to its various favorable agroecologies for wheat production.
However, one major challenge to boosting wheat production and yields is farmersâ vulnerability to rapidly evolving wheat diseases like wheat rusts.
The Ethiopian highlands have long been known as hot spots for stem and yellow wheat rusts caused by the fungus Puccinia spp., which can spread easily under favorable climatic conditions. Such threats may grow with a changing climate.
Recurrent outbreaks of the two rusts destroyed significant areas of popular wheat varieties. In 2010, a yellow rust epidemic severely affected the popular Kubsa variety. In 2013/14, farmers in the Arsi and Bale zones saw a new stem rust race destroy entire fields of the bread wheat Digalu variety.
In response to the 2010 yellow rust outbreak, the government and non-government organizations, seed enterprises and other development supporters increased the supply of yellow rust resistant varieties like Kakaba and Dandaâa.
Fungicide is not the only solution for wheat smallholder farmers
Two household panel surveys during the 2009/10 main cropping season, before the yellow rust epidemic, and during the 2013/14 cropping season analyzed farmersâ exposure to wheat rusts and their coping mechanisms. From the survey, 44% of the wheat farming families reported yellow rust in their fields during the 2010/11 epidemic.
Household data analysis looked at the correlation between household characteristics, their coping strategies against wheat rust and farm yields. The study revealed there was a 29 to 41% yield advantage by increasing wheat area of the new, resistant varieties even under normal seasons with minimum rust occurrence in the field. Continuous varietal development in responding to emerging new rust races and supporting the deployment of newly released rust resistant varieties could help smallholders cope against the disease and maintain improved yields in the rust prone environments of Ethiopia.
The case study showed that apart from using fungicides, increasing wheat area under yellow rust resistant varieties, increasing diversity of wheat varieties grown, or a combination of these strategies were the main coping mechanisms farmers had taken to prevent new rust damages. Large-scale replacement of highly susceptible varieties by new rust resistant varieties was observed after the 2010/11 epidemic.
The most significant wheat grain yield increases were observed for farmers who increased both area under resistant varieties and number of wheat varieties grown per season.
The additional yield gain thanks to the large-scale adoption of yellow rust resistant varieties observed after the 2010/11 epidemic makes a very strong case to further strengthen wheat research and extension investments, so that more Ethiopian farmers have access to improved wheat varieties resistant to old and newly emerging rust races.
How to track adoption and assess the impact of maize and wheat varieties? Some of the methods used until now, like farmersâ recall surveys, have various limitations. In addition to relying exclusively on peopleâs 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 âgold standardâ 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 countryâs 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), Ethiopiaâs 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.
CIMMYT scientists Dave Hodson (left), Bekele Abeyo (center) and Sarah Hearne participated in the workshop.
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.
Members of the International Maize Improvement Consortium Africa (IMIC – Africa) and other maize and wheat research partners discovered the latest innovations in seed and agronomy at Embu and Naivasha research stations in Kenya on August 27 and 28, 2019. The International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture & Livestock Research Organization (KALRO) held their annual partner field days to present sustainable solutions for farmers to cope with poor soils, a changing climate and emerging diseases and pests, such as wheat rust, maize lethal necrosis or fall armyworm.
Versatile seeds and conservation agriculture offer farmers yield stability
âMaize is food in Kenya. Wheat is also gaining importance for our countries in eastern Africa,â KALRO Embu Center Director, Patrick Gicheru, remarked. âWe have been collaborating for many years with CIMMYT on maize and wheat research to develop and disseminate improved technologies that help our farmers cope against many challenges,â he said.
Farmers in Embu, like in most parts of Kenya, faced a month delay in the onset of rains last planting season. Such climate variability presents a challenge for farmers in choosing the right maize varieties. During the field days, CIMMYT and KALRO maize breeders presented high-yielding maize germplasm adapted to diverse agro-ecological conditions, ranging from early to late maturity and from lowlands to highlands.
JoĂŁo Saraiva, from the Angolan seed company Jardins dâAyoba, said having access to the most recent improved maize germplasm is helpful for his young seed company to develop quality seeds adapted to farmersâ needs. He is looking for solutions against fall armyworm, as the invasive species is thriving in the Angolan tropical environment. He was interested to hear about CIMMYTâs progress to identify promising maize lines resistant to the caterpillar. Since fall armyworm was first observed in Africa in 2016, CIMMYT has screened almost 1,200 inbred lines and 2,900 hybrids for tolerance to fall armyworm.
âHopefully, we will be developing and releasing the first fall armyworm-tolerant hybrids by the first quarter of 2020,â announced B.M. Prasanna, director of CIMMYTâs Global Maize Programme and the CGIAR Research Program on Maize (MAIZE).
âThrough continuous innovations to build varieties that perform well despite dry spells, heat waves or disease outbreak, maize scientists have been able to deliver significant yield increases each year across various environments,â explained Prasanna. âThis genetic gain race is important to respond to growing grain demands despite growing climate risks and declining soil health.â
Berhanu Tadesse, maize breeder at the Ethiopian Institute for Agricultural Research (EIAR), was highly impressed by the disease-free, impeccable green maize plants at Embu station, remembering the spotted and crippled foliage during a visit more than a decade ago. This was âvisual proof of constant progress,â he said.
For best results, smallholder farmers should use good agronomic practices to conserve water and soil health. KALRO agronomist Alfred Micheni demonstrated different tillage techniques during the field tour including the furrow ridge, which is adapted to semi-arid environments because it retains soil moisture.
A vibrant local seed industry is needed for farmers to access improved varieties. Seed growers must be able to produce pure, high-quality seeds at competitive costs so they can flourish in business and reach many smallholder farmers.
Double haploid technology enables breeders to cut selection cycles from six to two, ultimately reducing costs by one third while ensuring a higher level of purity. Sixty percent of CIMMYT maize lines are now developed using double haploid technology, an approach also available to partners such as the Kenyan seed company Western Seeds.
The Seed Production Technology for Africa (SPTA) project, a collaboration between CIMMYT, KALRO, Corteva Agriscience and the Agricultural Research Council, is another innovation for seed companies enabling cheaper and higher quality maize hybrid production. Maize plants have both female and male pollen-producing flowers called tassels. To produce maize hybrids, breeders cross two distinct female and male parents. Seed growers usually break the tassels of female lines manually to avoid self-pollination. SPTA tested a male sterility gene in Kenya and South Africa, so that female parents did not produce pollen, avoiding a detasseling operation that damages the plant. It also saves labor and boosts seed yields. Initial trial data showed a 5 to 15% yield increase, improving the seed purity as well.
World-class research facilities to fight new and rapidly evolving diseases
The KALRO Naivasha research station has hosted the maize lethal necrosis (MLN) quarantine and screening facility since 2013. Implementing rigorous phytosanitary protocols in this confined site enables researchers to study the viral disease first observed in Africa 2011 in Bomet country, Kenya. Working with national research and plant health organizations across the region and the private sector, MLN has since been contained.
A birdâs eye view of the demonstration plots is the best testimony of the impact of MLN research. Green patches of MLN-resistant maize alternate with yellow, shrivelled plots. Commercial varieties are susceptible to the disease that can totally wipe out the crop, while new MLN-resistant hybrids yield five to six tons per hectare. Since the MLN outbreak in 2011, CIMMYT has released 19 MLN-tolerant hybrids with drought-tolerance and high-yielding traits as well.

A major challenge to achieving food security is to accelerate the varietal replacement on the market. CIMMYT scientists and partners have identified the lengthy and costly seed certification process as a major hurdle, especially in Kenya. The Principal Secretary of the State Department for Research in the Ministry of Agriculture, Livestock, and Fisheries, Hamadi Boga, pledged to take up this issue with the Kenya Plant and Health Inspectorate Service (KEPHIS).
âSuch rapid impact is remarkable, but we cannot rest. We need more seed companies to pick up these new improved seeds, so that our research reaches the maximum number of smallholders,ââ concluded Prasanna.

From July 22â26, the Stress Tolerant Maize for Africa (STMA) project organized a training in Adama, Ethiopia to update maize technicians on recent developments in maize research, data collection and seed production. The training was designed to stimulate good breeding programs, good data collection in trial and nurseries, production of better quality seed and development of improved varieties. Around 25 trainees attended, mainly from maize breeding research centers. Similar trainings were conducted in all STMA project countries over the last three and a half years.
CIMMYT staff from Ethiopia, Kenya and Zimbabwe and staff from the Ethiopian Institute of Agricultural Research (EIAR) Bako Research Center delivered training on methodologies and gave practical demonstrations on tablets. Presentations focused on the origin and botany of the maize plant, constraints to maize production in Ethiopia, data collection, breeding for abiotic stresses, new tools for phenotyping, maize lethal necrosis (MLN), and seed quality control.
Mandefro Nigussie, Director General of EIAR, said that the training was important because it addressed data collection. âIf we are missing the data, we are missing the investment of the country,â he noted. He recognized CIMMYTâs culture in empowering research centers through trainings. The role of EIAR is to generate, test, disseminate and scale technologies. Therefore, having technicians who are aware of the recent developments in their areas is crucial.
Cosmos Magorokosho, maize breeder and STMA project leader, said that the core components of the training were to give technicians a strong understanding of the basics of maize and the physiology of maize plant. The knowledge they gained from this training will support them during data collection and when breeding for resistance to diseases and pests and improved seed production.
Upon completing five days training, all trainees received certificates along with the presentations and other relevant documents for future reference. CIMMYT maize breeder Dagne Wegary said he appreciated the active participation and dedication of the trainees and the interest they showed to improve their knowledge and skills. He reminded them that this is the start of a long journey and they will have to use the knowledge and skills gained to help farmers produce more and ensure food security. Trainees reflected that the training increased their existing knowledge in maize breeding and helped them to understand the current developments in the area. They said they would directly apply what they have learned and transfer the knowledge to other colleagues working in maize breeding.
MARPLE (Mobile and Real-time PLant disEase) Diagnostics is a revolutionary mobile lab developed by a team from the John Innes Centre (JIC), the International Maize and Wheat Improvement Center (CIMMYT) and the Ethiopian Institute of Agricultural Research (EIAR). It uses nanopore sequence technology to rapidly diagnose and monitor wheat rust in farmersâ fields.
Designed to be used without constant electricity and in varying temperatures, the suitcase-sized lab allows researchers to identify wheat rust to strain level in just 48 hours â something that used to take months using other tools.
The MARPLE team was recognized as Innovator of the Year for international impact in 2019 by the UK Biotechnology and Biological Sciences Research Council (BBSRC).
A new video from the John Innes Centre shows how the MARPLE Diagnostics kit will allow Ethiopia to quickly identify wheat rust strains, instead of sending samples to labs abroad.

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.

On May 15, 2019, as part of the CGIAR System Council meeting held at the ILRI campus in Addis Ababa, Ethiopia, around 200 Ethiopian and international research and development stakeholders convened for the CGIAR Agriculture Research for Development Knowledge Share Fair. This exhibition offered a rare opportunity to bring the country’s major development investors together to learn and exchange about how CGIAR investments in Ethiopia help farmers and food systems be more productive, sustainable, climate resilient, nutritious, and inclusive.
Under the title One CGIAR â greater than the sum of its parts â the event offered the opportunity to highlight close partnerships between CGIAR centers, the Ethiopian government and key partners including private companies, civil society organizations and funding partners. The fair was organized around the five global challenges from CGIAR’s business plan: planetary boundaries, sustaining food availability, promoting equality of opportunity, securing public health, and creating jobs and growth. CGIAR and its partners exhibited collaborative work documenting the successes and lessons in working through an integrated approach.
There were 36 displays in total, 5 of which were presented by CIMMYT team members. Below are the five posters presented.
How can the data revolution help deliver better agronomy to African smallholder farmers?
This sustainability display showed scalable approaches and tools to generate site-specific agronomic advice, developed through the Taking Maize Agronomy to Scale in Africa (TAMASA) project in Nigeria, Tanzania and Ethiopia.
Maize and wheat: Strategic crops to fill Ethiopiaâs food basket
This poster describes how CGIAR works with Ethiopiaâs research & development sector to support national food security priorities.
Addressing gender norms in Ethiopiaâs wheat sector
Research shows that restrictive gender norms prevent womenâs ability to innovate and become productive. This significantly impacts Ethiopiaâs economy (over 1% GDP) and family welfare and food security.
Quality Protein Maize (QPM) for better nutrition in Ethiopia
With the financial support of the government of Canada, CIMMYT together with national partners tested and validated Quality Protein Maize as an alternative to protein intake among poor consumers.
Appropriate small-scale mechanization
The introduction of small-scale mechanization into the Ethiopian agriculture sector has the potential to create thousands of jobs in machinery service provision along the farming value chain.

The team â Diane Saunders of the John Innes Centre (JIC), Dave Hodson of the International Maize and Wheat Improvement Center (CIMMYT) and Tadessa Daba of the Ethiopian Institute for Agricultural Research (EIAR) â was presented with the award at an event at the London Science Museum on May 15, 2019. In the audience were leading figures from the worlds of investment, industry, government, charity and academia, including the U.K.âs Minister of State for Universities, Science, Research and Innovation, Chris Skidmore.
The BBSRC Innovator of the Year awards, now in their 11th year, recognize and support individuals or teams who have taken discoveries in bioscience and translated them to deliver impact. Reflecting the breadth of research that BBSRC supports, they are awarded in four categories of impact: commercial, societal, international and early career. Daba, Hodson and Saunders were among a select group of 12 finalists competing for the four prestigious awards. In addition to international recognition, they received ÂŁ10,000 (about $13,000).
âI am delighted that this work has been recognized,â Hodson said. âWheat rusts are a global threat to agriculture and to the livelihoods of farmers in developing countries such as Ethiopia. MARPLE diagnostics puts state-of-the-art, rapid diagnostic results in the hands of those best placed to respond: researchers on the ground, local government and farmers.â
On-the-ground diagnostics
The MARPLE diagnostic kit is the first operational system in the world using nanopore sequence technology for rapid diagnostics and surveillance of complex fungal pathogens in the field.
In its initial work in Ethiopia, the suitcase-sized field test kit has positioned the country â one of the regionâs top wheat producers â as a world leader in pathogen diagnostics and forecasting. Generating results within 48 hours of field sampling, the kit represents a revolution in plant disease diagnostics. Its use will have far-reaching implications for how plant health threats are identified and tracked into the future.
MARPLE is designed to run at a field site without constant electricity and with the varying temperatures of the field.
âThis means we can truly take the lab to the field,â explained Saunders. âPerhaps more importantly though, it means that smaller, less-resourced labs can drive their own research without having to rely on a handful of large, well-resourced labs and sophisticated expertise in different countries.â
In a recent interview with JIC, EIAR Director Tadessa Daba said, âwe want to see this project being used on the ground, to show farmers and the nation this technology works.â

Development of the MARPLE diagnostic kit was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the CGIAR Platform for Big Data in Agricultureâs Inspire Challenge. Continued support is also provided by the BBSRCâs Excellence with Impact Award to the John Innes Centre and the Delivering Genetic Gain in Wheat project, led by Cornell University and funded by the UKâs Department for International Development (DFID) and the Bill & Melinda Gates Foundation.
The International Maize and Wheat Improvement Center (CIMMYT) and Ethiopiaâs Ministry of Agriculture held a workshop on March 23, 2019, with the main stakeholders of the agricultural research and seed sectors to discuss how Quality Protein Maize (QPM) production and demand could be expanded, to ensure lasting nutrition benefits for consumers and incomes for farmers.
Maize is the second most cultivated cereal in Ethiopia, with 66% of cereal-farming households cultivating maize on 2.1 million hectares. It is a primary staple food in the major maize-growing areas as well as a source of feed for animals and a raw material for industries. With increasing pressures from climate change and population growth, maize is likely to be key to meeting the challenges of food and income security.
Despite its high productivity, maize grain does not provide balanced protein for human consumption. It is deficient in two essential amino acids, lysine and tryptophan, putting those who consume maize without alternative protein sources at risk of malnutrition and stunted growth and development. Infants and young children are especially at risk. Complementary and alternative sources of protein such as legumes or animal products â meat, eggs and milk â are often inaccessible or unaffordable to the poorest households.
QPM is a type of maize, developed through conventional breeding, that contains nearly twice the amount of tryptophan and lysine compared to common varieties. Research shows that eating QPM can improve quality protein intake among young children and QPM is nutritionally advantageous over conventional maize, especially for families with an undiversified diet dominated by maize.
Since 2012, CIMMYT has been working with the Ethiopian Institute of Agricultural Research (EIAR), the Ministry of Agriculture and other strategic partners like the Ethiopian Public Health Institute (EPHI), Sasakawa Global 2000 (SG2000) and Farm Radio International, to improve food and nutritional security in Ethiopian farming communities through the promotion and expansion of QPM under the Nutritious Maize for Ethiopia (NuME) project. This project built on the achievements of a previous project called Quality Protein Maize Development (QPMD). Both projects were financed by the government of Canada.

Ethiopians are willing to pay for QPM
During the workshop, CIMMYT senior scientist and NuME project leader Adefris Teklewold talked about the favorable conditions that had contributed to the projectâs success and which are also grounds for sustainability: government policies and strategies, technical knowledge and technology, and the productive collaboration among partners.
The NuME project operated in 36 woredas, or districts, of the Amhara, Oromia, SNNP and Tigray regions. More than 68% of the target population is now aware of the nutritional benefits of QPM, boosting the demand for the nutritious maize.
Four QPM varieties have been released since the beginning of the project and at least two promising varieties are in the pipeline. Figures show an adoption rate of 11% in the projectâs target areas. Today, the main issue to reach out more people is shortage of seed.
The project team trained people in food preparation and organized events to demonstrate the benefits of QPM. One fifth of the 1,788 QPM demonstrations were managed entirely by women. Through demonstrations and blind tastings, people could check that QPM maize did not affect the taste or functional properties of traditional foods like dabo bread or injera flatbread. For instance, they realized that injera using QPM also stayed moist and could be rolled easily. In addition, a recent study on school feeding revealed that dishes made from QPM received wider acceptance.

Beyond the NuME project
Germame Garuma, Director General of Extension at the Ministry of Agriculture, said that âQPM is an important solution to help us improve the nutrition situation in the country.â The Ethiopian government now aims to ensure 10% of the total maize growing area is planted with QPM. Ethiopia has included QPM as a key intervention in national strategies and programs, such as the Agriculture Growth Program-II and the Seqota Declaration.
Garuma called on all government offices at various levels and NGOs working in the agriculture and nutrition sector to continue the promotion of QPM. Workshop participants drew a roadmap with four focus areas: overall coordination, dissemination, technology generation and seed production. With the leadership of the Ministry of Agriculture, more families will be able to improve their diet with QPM in the future.
Dagmo Nour, Project Manager at Global Affairs Canada, expressed interest in engaging further with CIMMYT and its partners to ensure the sustainability and scaling of QPM efforts by addressing critical issues with Ethiopian seed systems.

The Drought Tolerant Maize for Africa project aims to mitigate drought and other constraints to maize production in sub-Saharan Africa, increasing maize yields by at least one ton per hectare under moderate drought and with a 20 to 30 percent increase over farmersâ current yields, benefiting up to 40 million people in 13 African countries. The project brings together farmers, research institutions, extension specialists, seed producers, farmer community organizations and non-governmental organizations. It is jointly implemented by CIMMYT and the International Institute for Tropical Agriculture, in close collaboration with national agricultural research systems in participating nations. Millions of farmers in the region are already benefiting from the outputs of this partnership, which includes support and training for African seed producers and promoting vibrant, competitive seed markets.
Achievements:
Between 2007 and 12, participants marketed or otherwise made available 60 drought tolerant hybrids and 57 open-pollinated varieties to smallholder farmers
In addition to drought tolerance, the new varieties and hybrids also possess such desirable traits as resistance to major diseases
Engage government officials in policy dialogue to help fast-track varietal releases and fosters competitive seed markets and more
widespread access to quality seed at affordable prices
Help ensure farmersâ access to the best possible products and services, coordinate various capacity-building events and
activities for maize breeders, technicians, seed producers, extension workers, non-government organizations and farmer groups
Provide technical and advisory support to 50 African undergraduate and 28 African graduate students
Expand smallholder farmersâ use of drought and other stress tolerant maize seed to benefit 30 to 40 million people and provide added grain worth $160-200 million each year in drought-affected areas of sub-Saharan Africa

The Ethiopian wheat sector has seen progress since the early 2000s, more than doubling the average farm yields from 1.13 tons per hectare in 1998/99 to 2.74 tons per hectare in 2017/18. Progressive farmers who plant improved wheat varieties and follow recommended agronomic practices could harvest four to six tons per hectare in high-potential wheat growing areas. However, the production is not keeping up with the growing wheat demand: imports reached over 1.5 million tons last year. The Ethiopian government has announced recently that the country should become wheat self-sufficient over the next four years.
One of the biggest wheat production challenges in Ethiopia has been the stem rust and yellow rust diseases caused by Pucccinia spp, which severely affected popular wheat varieties like Kubsa, Galema and Digalu that wiped out from production.
In response to these losses, the International Maize and Wheat Improvement Center (CIMMYT) started an emergency project to multiply and disseminate rust-resistant wheat varieties in the affected regions in 2014, with support from USAID.
The following year, CIMMYT launched the Seed Multiplication and Delivery of High Yielding Rust Resistant Bread and Durum Wheat Varieties to Ethiopian Farmers project. It benefitted people in 54 woredas (districts) of 4 regions: Amhara, Oromia, SNNP and Tigray. CIMMYT collaborated with the Ethiopian Institute of Agricultural Research (EIAR), regional agricultural research institutes and the regional bureaus of agriculture.
This wheat seed scaling project wrapped up with a closure workshop on March 7, 2019. Organized by CIMMYT and EIAR, it gathered representatives from USAID, policymakers, researchers and other governmental and non-governmental institutions.

State minister of agriculture Aynalem Nigussie noted that the project boosted farmersâ productivity thanks to better seeds, improved farming practices and increased knowledge to deal with wheat rust diseases. She recognized that the project aligned with national priorities, as the government is devising a new seed policy to address the current challenges of the Ethiopian wheat seed sector.
CIMMYTâs representative in Ethiopia, Bekele Abeyo, highlighted some of the project outcomes. Some of the achievements in the past four years included the release and demonstration of 23 wheat varieties â 18 bread and 5 durum types â, increased access to these improved seeds for 131,132 households and production of 39,750 tons of wheat grain. Extension agents from 54 woredas participated in training in wheat rust management, recommended agronomic packages for the new wheat varieties, and field data collection and management.
Lessons learned
Abeyo explained that the project could reach a high number of farmers thanks to effective teamwork between the various stakeholders, seed support on revolving bases and a decentralized seed production to reach even remote places. Clustering farmersâ plots favored quality seed production.
Participants flagged weak market linkages, particularly for farmers producing durum wheat, , as a bottleneck to address. Workshop participants recommended the establishment of a wheat task force involving the private sector and with continuous support from funders like USAID.
The director general of EIAR, Mandefro Nigusse, said that the issues raised are inputs for further actions, and some will have to be directed to researchers and breeders to come up with additional solutions for the challenges the wheat sector is facing.
Eyasu Abrha, Advisor to the Minister of Agriculture, officially closed the workshop. He noted that the government of Ethiopia is putting effort into ensuring nutritional and food security, and that projects such as this one are important to address critical challenges in the sector. Abrha acknowledged the support of CIMMYT, EIAR and USAID, and called for a continued collaboration with the government of Ethiopia to meet nutritional and food security goals.
