Assessing the effectiveness of a “wheat holiday” for preventing blast in the lower Gangetic plains

Written by Marcia MacNeil on February 22, 2019. Posted in News.

Wheat blast — one of the world’s most devastating wheat diseases — is moving swiftly into new territory in South Asia.

In an attempt to curb the spread of this disease, policymakers in the region are considering a “wheat holiday” policy: banning wheat cultivation for a few years in targeted areas. Since wheat blast’s Magnaporthe oryzae pathotype triticum (MoT) fungus can survive on seeds for up to 22 months, the idea is to replace wheat with other crops, temporarily, to cause the spores to die. In India, which shares a border of more than 4,000 km with Bangladesh, the West Bengal state government has already instituted a two-year ban on wheat cultivation in two districts, as well as all border areas. In Bangladesh, the government is implementing the policy indirectly by discouraging wheat cultivation in the severely blast affected districts.

CIMMYT researchers recently published in two ex-ante studies to identify economically feasible alternative crops in Bangladesh and the bordering Indian state of West Bengal.

Alternative crops

The first step to ensuring that a ban does not threaten the food security and livelihoods of smallholder farmers, the authors assert, is to supply farmers with economically feasible alternative crops.

In Bangladesh, the authors examined the economic feasibility of seven crops as an alternative to wheat, first in the entire country, then in 42 districts vulnerable to blast, and finally in ten districts affected by wheat blast. Considering the cost of production and revenue per hectare, the study ruled out boro rice, chickpeas and potatoes as feasible alternatives to wheat due to their negative net return. In contrast, they found that cultivation of maize, lentils, onions, and garlic could be profitable.

The study in India looked at ten crops grown under similar conditions as wheat in the state of West Bengal, examining the economic viability of each. The authors conclude that growing maize, lentils, legumes such as chickpeas and urad bean, rapeseed, mustard and potatoes in place of wheat appears to be profitable, although they warn that more rigorous research and data are needed to confirm and support this transition.

Selecting alternative crops is no easy task. Crops offered to farmers to replace wheat must be appropriate for the agroecological zone and should not require additional investments for irrigation, inputs or storage facilities. Also, the extra production of labor-intensive and export-oriented crops, such as maize in India and potatoes in Bangladesh, may add costs or require new markets for export.

There is also the added worry that the MoT fungus could survive on one of these alternative crops, thus completely negating any benefit of the “wheat holiday.” The authors point out that the fungus has been reported to survive on maize.

A short-term solution?

In both studies, the authors discourage a “wheat holiday” policy as a holistic solution. However, they leave room for governments to pursue it on an interim and short-term basis.

In the case of Bangladesh, CIMMYT agricultural economist and lead author Khondoker Mottaleb asserts that a “wheat holiday” would increase the country’s reliance on imports, especially in the face of rapidly increasing wheat demand and urbanization. A policy that results in complete dependence on wheat imports, he and his co-authors point out, may not be politically attractive or feasible. Also, the policy would be logistically challenging to implement. Finally, since the disease can potentially survive on other host plants, such as weeds and maize, it may not even work in the long run.

In the interim, the government of Bangladesh may still need to rely on the “wheat holiday” policy in the severely blast-affected districts. In these areas, they should encourage farmers to cultivate lentils, onions and garlic. In addition, in the short term, the government should make generic fungicides widely available at affordable prices and provide an early warning system as well as adequate information to help farmers effectively combat the disease and minimize its consequences.

In the case of West Bengal, India, similar implications apply, although the authors conclude that the “wheat holiday” policy could only work if Bangladesh has the same policy in its blast-affected border districts, which would involve potentially difficult and costly inter-country collaboration, coordination and logistics.

Actions for long-term success

The CIMMYT researchers urge the governments of India and Bangladesh, their counterparts in the region and international stakeholders to pursue long-term solutions, including developing a convenient diagnostic tool for wheat blast surveillance and a platform for open data and science to combat the fungus.

A promising development is the blast-resistant (and zinc-enriched) wheat variety BARI Gom 33 which the Bangladesh Agricultural Research Institute (BARI) released in 2017 with support from CIMMYT. However, it will take at least three to five years before it will be available to farmers throughout Bangladesh. The authors urged international donor agencies to speed up the multiplication process of this variety.

CIMMYT scientists in both studies close with an urgent plea for international financial and technical support for collaborative research on disease epidemiology and forecasting, and the development and dissemination of new wheat blast-tolerant and resistant varieties and complementary management practices — crucial steps to ensuring food security for more than a billion people in South Asia.

Wheat blast impacts

First officially reported in Brazil in 1985, where it eventually spread to 3 million hectares in South America and became the primary reason for limited wheat production in the region, wheat blast moved to Bangladesh in 2016. There it affected nearly 15,000 hectares of land in eight districts, reducing yield by as much as 51 percent in the affected fields.

Blast is devilish: directly striking the wheat ear, it can shrivel and deform the grain in less than a week from the first symptoms, leaving farmers no time to act. There are no widely available resistant varieties, and fungicides are expensive and provide only a partial defense. The disease, caused by the fungus Magnaporthe oryzae pathotype triticum (MoT), can spread through infected seeds as well as by spores that can travel long distances in the air.

South Asia has a long tradition of wheat consumption, especially in northwest India and Pakistan, and demand has been increasing rapidly across South Asia. It is the second major staple in Bangladesh and India and the principal staple food in Pakistan. Research indicates 17 percent of wheat area in Bangladesh, India, and Pakistan — representing nearly 7 million hectares – is vulnerable to the disease, threatening the food security of more than a billion people.

CIMMYT and its partners work to mitigate wheat blast through projects supported by U.S. Agency for International Development (USAID), the Bill & Melinda Gates Foundation, the Australian Centre for International Agricultural Research (ACIAR), the Indian Council for Agricultural Research (ICAR), the CGIAR Research Program on Wheat and the CGIAR Platform for Big Data in Agriculture.

Women’s equality crucial for Ethiopia’s agricultural productivity

Written by Mary Donovan on February 17, 2019. Posted in In the media.

The Government of Ethiopia recently announced an ambitious goal to reach wheat self-sufficiency by 2022, eliminating expensive wheat imports and increasing food security.

However, a new report based on a four-year research project on gender and productivity in Ethiopia’s wheat sector indicates that a lack of technical gender research capacity, a shortage of gender researchers and low implementation of gender-focused policies is hampering these efforts.

New partnership announced for sustainable maize production in Colombia

Written by on February 14, 2019. Posted in Press releases.

Palmira (Colombia), February 14, 2019 — AGROSAVIA, Colombia’s leading not-for-profit organization for agricultural research and technology transfer, the International Center for Tropical Agriculture (CIAT) and the International Maize and Wheat Improvement Center (CIMMYT) have signed a five-year agreement that aims to boost maize production.

The new project will develop maize varieties adapted to the country’s farming conditions, and will promote sustainable intensification technologies and practices among Colombian farmers.

“We should be able to release the first high-yielding maize variety for Colombia in three years”, said Bram Govaerts, CIMMYT’s director of Innovative Business Strategies and regional representative for the Americas.

To achieve this goal, CIMMYT will provide AGROSAVIA’s breeding program with two thousand advanced lines, developed by combining native maize from Colombia with conventionally improved varieties.

“At both institutions we believe that Colombia can increase production to close the big gap between domestic maize consumption and imports”, said AGROSAVIA’s Executive Director, Juan Lucas Restrepo. “With this agreement, we will have more powerful local capacities and once again a Colombian maize research program for Colombians”.

Although experts agree that Colombian farmers could potentially produce more than 10 tons per hectare, the country’s average yield is currently 3.6 tons per hectare.

“With this agreement, the sister CGIAR centers CIMMYT and CIAT give a first step in the implementation of Maize for Colombia, an ambitious plan that will sustainably increase Colombia’s maize output by building on the learnings and achievements of a successful project implemented in Mexico called MasAgro,” said Govaerts.

Colombia’s Minister of Agriculture and Rural Development, Andrés Valencia, CIAT’s Director General, Rubén Echeverría, Juan Lucas Restrepo, and Bram Govaerts participated in the launch ceremony for the new agreement, which was signed at CIAT’s headquarters.

Experts analyze food systems at EAT-Lancet Commission report launch in Ethiopia

Written by on February 13, 2019. Posted in News.

Earlier this year, the EAT-Lancet Commission published a groundbreaking report linking healthy diets and sustainable food systems. It proposed scientific targets that meet both the Sustainable Development Goals (SDGs) and the Paris Agreement action plan to reduce carbon emissions. Since then, more than 20 launch events have been scheduled around the globe, including Addis Ababa, Ethiopia.

On February 7, the African Union hosted the EAT-Lancet Commission on healthy diets for sustainable food systems. Government officials, researchers and experts attended the “Food Systems Dialogue on Ethiopia” and developed a list of recommendations going forward. Some of these included at least 10 percent resource allocation to agriculture, the creation of functional and efficient internal markets for enhancing food distribution within the country, post-harvest loss reduction, and stronger collaboration between government and other stakeholders.

“The report has drawn the attention of policy makers, civil society and donors,” said Kindie Tesfaye Fantaye, a researcher and crop modeler at the International Maize and Wheat Improvement Center (CIMMYT). “The event was a good opportunity to create awareness on the chronic problems of stunting and malnutrition in Africa, and agriculture’s central role in contributing to effective solutions.”

Tesfaye Fantaye said CIMMYT’s work is well aligned with the report’s recommendations. In addition to research on sustainable intensification approaches that improve livelihoods while reducing the environmental footprint, CIMMYT explores ways to reduce postharvest losses and increase the nutritional quality of food through biofortification.

During a high-level side event, the commissioners indicated that the report is in-line with the different African Union policies and strategies, including the Malabo Declaration on Agriculture and Postharvest Losses, Agenda 2063 and Comprehensive Africa Agriculture Development Program (CAADP).

“The power of food is its connection. If we get it right, it brings us to a healthy people and a healthy planet,” said Gunhild Anker Stordalen, the founder and executive chair of EAT Foundation.

Precision planters boost maize yields in Pakistan

In the northwestern province of Pakistan, near the Afghan border, the International Maize and Wheat Improvement Center (CIMMYT) is helping connect farmers with precision planters to support higher maize yields and incomes. Maize is one of the most important cereals in Pakistan, but in the province of Khyber Pakhtunkhwa yields are significantly lower than the national average. The majority of maize farmers in this province have less than five acres of land and limited access to resources, including high-quality maize seed and mechanization.

Under the Agricultural Innovation Program (AIP) for Pakistan, CIMMYT introduced push row planters in 2016 to help farmers to get a uniform crop stand and save labor costs and time as compared to traditional planting practices. CIMMYT has since then partnered with Greenland Engineering to import tractor-operated precision maize planters. These precision planters allow farmers to plant two rows of maize in one pass and evenly distribute both seeds and fertilizer.

“Optimum planting density in combination with nutrient supply is key to getting the maximum maize yield,” says Muhammad Asim, a senior researcher with the Cereal Crops Research Institute (CCRI). “The precision planter helps farmers achieve this while also getting a uniform crop stand and uniform cobs.”

*Maize farmer Jalees Ahmed (right) operates his push row planter. (Photo: Kashif Syed/CIMMYT)*

Jalees Ahmed, a smallholder maize farmer from the Nowshera district, Khyber Pakhtunkhwa, received a push row planter through CIMMYT’s AIP program. He used to hire six laborers to plant one acre of maize, but with the push row planter, Jalees only needs to hire one laborer and benefits from a more uniform crop.

Raham Dil, another farmer in the Mardan district, recently purchased a push row planter for his farm which he also rents to fellow farmers in the area.

Both Ahmed and Dil say these planters have made it easier to support their families financially. Interest in precision planters continues to grow.

Last fall, more than 80 farmers attended a field day in the Nowshera district where CIMMYT researchers demonstrated how to use the precision planter to sow maize. CIMMYT’s country representative for Pakistan, Imtiaz Muhammad, highlighted the importance of mechanized maize planting for farmers and CIMMYT’s commitment to improve maize-based system productivity in less developed regions of the country.

The Agricultural Innovation Program for Pakistan is led by CIMMYT and funded by USAID. This project seeks to increase productivity and incomes by testing and promoting modern practices for agriculture’s major sub-sectors in the country.

Smallholder wheat production can cut Africa’s costly grain imports

Written by Mike Listman on February 8, 2019. Posted in News.

International scientists are working with regional and national partners in sub-Saharan Africa to catalyze local wheat farming and help meet the rapidly rising regional demand for this crop.

The specialists are focusing on smallholder farmers in Rwanda and Zambia, offering them technical and institutional support, better links to markets, and the sharing of successful practices across regions and borders, as part of the project “Enhancing smallholder wheat productivity through sustainable intensification of wheat-based farming systems in Rwanda and Zambia.”

“Work started in 2016 and has included varietal selection, seed multiplication, and sharing of high-yielding, locally adapted, disease-resistant wheat varieties,” said Moti Jaleta, a socioeconomist at the International Maize and Wheat Improvement Center (CIMMYT) who leads the project. “Our knowledge and successes in smallholder wheat production and marketing will also be applicable in Madagascar, Mozambique, and Tanzania.”

Maize is by far the number-one food crop in sub-Saharan Africa but wheat consumption is increasing fast, driven in part by rapid urbanization and life-style changes. The region annually imports more than 15 million tons of wheat grain, worth some US$ 3.6 billion at current prices. Only Ethiopia, Kenya, and South Africa grow significant amounts of wheat and they are still net importers of the grain.

“Growing more wheat where it makes sense to do so can help safeguard food security for people who prefer wheat and reduce dependence on risky wheat grain markets,” Jaleta explained. “We’re working in areas where there’s biophysical potential for the crop in rain-fed farming, to increase domestic wheat production and productivity through use of improved varieties and cropping practices.”

In addition to the above, participants are supporting the region’s wheat production in diverse ways:

Recommendations to fine-tune smallholder wheat value chains and better serve diverse farmers.
Testing of yield-enhancing farming practices, such as bed-and-furrow systems that facilitate efficient sowing and better weed control.
Testing and promotion of small-scale mechanization, such as power tillers, to save labor and improve sowing and crop establishment.
Exploring use of hand-held light sensors to precisely calibrate nitrogen fertilizer dosages throughout the cropping season.

Innocent Habarurema, wheat breeder in the Rwanda Agriculture and Animal Resources Development Board (RAB), cited recent successes in the release of improved, disease resistant wheat varieties, as well as engaging smallholder farmers in seed multiplication and marketing to improve their access to quality seed of those varieties.

“The main challenge in wheat production is the short window of time between wheat seasons, which doesn’t allow complete drying of harvested plants for proper threshing,” Habarurema explained. “Suitable machinery to dry and thresh the wheat would remove the drudgery of hand threshing and improve the quality of the grain, so that it fetches better prices in markets.”

*Millers, like this one in Rwanda, play a key role in wheat value chains.*

Critical wheat diseases in Zambia include spot blotch, a leaf disease caused by the fungus Cochliobolus sativus, and head blight caused by Fusarium spp., which can leave carcinogenic toxins in the grain, according to Batiseba Tembo, wheat breeder at the Zambian Agricultural Research Institute (ZARI).

“Developing and disseminating varieties resistant to these diseases is a priority in the wheat breeding program at Mt. Makulu Agricultural Research Center,” said Tembo. “We’re also promoting appropriate mechanization for smallholder farmers, to improve wheat production and reduce the enormous drudgery of preparing the soil with hand hoes.”

Participants in the project, which runs to 2020, met at Musanze, in Rwanda’s Northern Province, during February 5-7 to review progress and plan remaining activities, which include more widespread sharing of seed, improved practices, and other useful outcomes.

“There was interest in trying smallholder winter wheat production under irrigation in Zambia to reduce the disease effects normally experienced in rainfed cropping,” said Jaleta, adding that the costs and benefits of irrigation, which is rarely used in the region, need to be assessed.

Project participants may also include in selection trials wheat varieties that have been bred to contain enhanced grain levels of zinc, a key micronutrient missing in the diets of many rural Africa households.

“The project will also push for the fast-track release and seed multiplication of the best varieties, to get them into farmers’ hands as quickly as possible,” Jaleta said.

In addition to CIMMYT, RAB, and ZARI, implementing partners include the Center for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA). Generous funding for the work comes from the International Fund for Agricultural Development (IFAD) and the CGIAR Research Program on Wheat.

BISA and PAU awarded for collaborative work on residue management

Written by Emma Orchardson on February 8, 2019. Posted in News.

The Borlaug Institute for South Asia-Punjab Agricultural University (BISA-PAU) joint team recently received an award from the Indian Society for Agricultural Engineers (ISAE) in recognition of their work on rice residue management using the Super Straw Management System, also known as Super SMS.

Developed and recommended by researchers at BISA and PAU in 2016, the Super SMS is an attachment for self-propelled combine harvesters which offers an innovative solution to paddy residue management in rice-wheat systems.

The Punjab government has made the use of the Super SMS mandatory for all combine harvesters in northwestern India.

The Super SMS gives farmers the ability to recycle residues on-site, reducing the need for residue burning and thereby reducing environmental pollution and improving soil health. Instead, the Super SMS helps to uniformly spread rice residue, which is essential for the efficient use of Happy Seeder technology and maintaining soil moisture in the field.

Harminder Singh Sidhu, a senior research engineer with the International Maize and Wheat Improvement Center (CIMMYT) working at BISA, stressed the need for more sustainable methods of dealing with residue. “Happy Seeder was found to be a very effective tool for direct sowing of wheat after paddy harvesting, using combine harvesters fitted with Super Straw Management System.”

BISA-PAU researchers received the ISAE Team Award 2018 at the 53^rd Annual Convention of ISAE, held from January 28 to January 30, 2019, at Baranas Hindu University in Varanasi, Uttar Pradesh state.

The director general of the Indian Council of Agricultural Research (ICAR), Trilochan Mohapatra, presented the award, acknowledging it as “a real team award which is making a difference on the ground.”

The recipients acknowledged the role of local industry partner New Gurdeep Agro Industries for its contributions to promoting the adoption of this machinery. Within eight months of commercialization in the Indian state of Punjab, over 100 manufacturers had begun producing the Super SMS attachment. Currently, more than 5,000 combine harvesters are equipped with it.

Scaling to new heights in agriculture

Written by Courtney Brantley on January 29, 2019. Posted in Features.

How to scale? This question frequently comes up as projects look to expand and replicate results. In order to sustain enduring impacts for projects after their lifetime, agricultural programs are turning to scaling strategies. These strategies look beyond the numbers that are reached within a project and include sustainability and transformation beyond the project context. Methods and tools exist that help anticipate realistic and responsible scaling pathways.

The Scaling team at the International Maize and Wheat Improvement Center (CIMMYT), led by Lennart Woltering, drives the initiative to incorporate scaling principles into existing and developing projects to maximize impact.

Maria Boa recently joined the team as Scaling Coordinator. Last year Boa and Woltering participated in regional meetings on scaling in Morocco, Tunisia and Vietnam, which highlighted the need for better dissemination of information on how to approach scaling, in addition to its benefits.

According to Boa, one of the key messages highlighted throughout these events was that in order for scaling to take hold and be integrated into projects, “…there needs to be a shift in mindset to accept that change is complex and that most projects only address a fraction of the problem.” This is essential in using scaling to effectively support long-term results.

At a workshop in Tunisia organized by ICARDA, IFAD and CIMMYT in November 2018, many participants expressed interest in scaling strategy tools, but were puzzled on how to integrate them into their specific projects. Many determined that they were stuck developing scaling strategies in an outdated framework, or one that strictly focused on using technological innovations. One participant admitted that she was skeptical of scaling perspectives because many did not lie in her field of expertise.

The November 2018 CCAFS SEA Conference on Scaling in Vietnam provided a platform for the sharing and learning of experiences in the scaling world. Some of the key messages from the event included the importance of scaling agricultural innovations taking place in complex systems of agricultural transformation, and the necessity of joint cooperation from all involved stakeholders and their openness to taking on challenges as a way to support sustainable system change.

According to Boa, scaling is a process that heavily relies on strategic collaboration for lasting impact. “Projects often don’t take into account how they’re a part of a larger chain of potential change,” she says.

Already recognized as a sustainable leader within scaling, CIMMYT is looking to strengthen scaling efforts in order to foster a more enduring impact within CIMMYT projects and beyond.

*Lennart Woltering presents at the CCAFS SEA Conference in Vietnam.*

Currently, the Scaling team at CIMMYT is conducting research on the “science of scaling” as it continues to function as a “help desk,” providing support integrating scaling principles in proposals and projects. Its primary role is to consider a project’s scaling needs and guide the development of an informed strategy to leverage efforts and resources. Boa hopes that by integrating responsible scaling approaches early on, projects can better balance the trade-offs associated with change.

Success in scaling is measured by a project’s enduring impact. However, stakeholders need more experience and capacity to see programs through to their end and be willing to monitor them beyond that lifespan. CIMMYT is developing and collecting the tools to support stakeholders with these specific capacities.

Developing a scaling strategy can also bring additional benefits: a discussion about scaling opens the door for raising awareness and fostering actions among different stakeholders towards system change and sustainable impact.

City dwellers in Africa and Asia increasingly choose wheat, research shows

Written by Mike Listman on January 23, 2019. Posted in News.

The developing world’s appetite for wheat is growing swiftly, driven in part by rising incomes, rapid urbanization and the expansion of families where both spouses work outside the house, according to a recent seminar by two international experts.

“Our research is picking up significant shifts in demand among cereals, including the increasing popularity of wheat in Asia and sub-Saharan Africa,” said Khondoker Mottaleb, socioeconomist for the International Maize and Wheat Improvement Center (CIMMYT), speaking at a seminar at the center on December 11, 2018.

In preliminary results of a study using household data from six countries in Asia and five in sub-Saharan Africa, Mottaleb and his associate, Fazleen Binti Abdul Fatah, senior lecturer at the University of Technology MARA, Malaysia, found that the households of both regions will eat more wheat by 2030, mainly in place of rice in Asia and of maize and other coarse grain cereals in Africa.

Speedy urbanization, higher incomes, population growth, and allied lifestyle changes are all driving this trend, said Fazleen. “Many urban women are working, so families are transitioning to bread and other convenient wheat-based foods and processed foods.”

A typical case according to Mottaleb is that of Bangladesh, a country whose population at 160 million is half that of the United States but with a geographical area equivalent to the US state of Ohio. The per capita GDP of Bangladesh grew from US$360 to US$1,516 during 2000-2017, and more than 35 percent of the country’s inhabitants now live in cities.

Meeting demand for wheat in Bangladesh

A 2018 paper by Mottaleb and fellow CIMMYT researchers shows that wheat consumption will increase substantially in Bangladesh by 2030 and the country needs to expand production or increase imports to meet the growing demand.

“The country purchases nearly 70 percent of its wheat at an annual cost near or exceeding US$1 billion, depending on yearly prices,” said Mottaleb. “Wheat prices are relatively low and wheat markets have been relatively stable, but if yields of a major wheat exporting country suddenly fall, say, from pest attacks or a drought, wheat markets would destabilize and prices would spike, as occurred in 2008 and 2011.”

In a 2018 study, the United Kingdom’s Agriculture and Horticulture Development Board (AHDB) cautioned that declining wheat cropping area worldwide and significant stockpiling by China — which holds nearly half the world’s wheat stocks but does not export any grain — were masking serious risk in global wheat markets.

A recent report ranked Bangladesh as the world’s fifth largest wheat importer. Since 2014-15 domestic wheat consumption there has increased by 57 percent from 4.9 million metric ton to 7.7 million metric tons. Last December, the Food and Agriculture Organization (FAO) of the United Nations forecast Bangladesh wheat import requirements of 6 million tons for this year — 34 percent above the previous five-year average following steady increases since 2012-13.

“The prevailing narrative has wealthier and more urban consumers shifting from basic foods to higher value foods, and this is doubtless occurring,” said Fazleen, “but our work shows a more nuanced scenario. In the traditional rice consuming economies in Asia, rural households are also eating more wheat, due to rapid dietary transformations.”

For Bangladesh, the researchers propose growing additional wheat on fallow and less-intensively-cropped land, as well as expanding the use of newer, high-yielding and climate-smart wheat varieties.

“Our work clearly shows the rising popularity of wheat across Asia and Africa,” said Mottaleb. “We urge international development agencies and policymakers to enhance wheat production in suitable areas, ensuring food security for the burgeoning number of people who prefer wheat and reducing dependence on risky wheat grain markets.”

In addition to the paper cited above, Mottaleb and colleagues have published recent studies on Bangladesh’s wheat production and consumption dynamics and changing food consumption patterns.

The authors thank the CGIAR Research Program on Wheat for its support for these studies.

New publications: Role of Modelling in International Crop Research

Written by Emma Orchardson on January 18, 2019. Posted in Publications.

“Crop modelling has the potential to significantly contribute to global food and nutrition security,” claim the authors of a recently published paper on the role of modelling in international crop research. “Millions of farmers, and the societies that depend on their production, are relying on us to step up to the plate.”

Among other uses, crop modelling allows for foresight analysis of agricultural systems under global change scenarios and the prediction of potential consequences of food system shocks. New technologies and conceptual breakthroughs have also allowed modelling to contribute to a better understanding of crop performance and yield gaps, improved predictions of pest outbreaks, more efficient irrigation systems and the optimization of planting dates.

While renewed interest in the topic has led in recent years to the development of collaborative initiatives such as the Agricultural Model Intercomparison and Improvement Project (AgMIP) and the CGIAR Platform for Big Data in Agriculture, further investment is needed in order to improve the collection of open access, easy-to-use data available for crop modelling purposes. Strong impact on a global scale will require a wide range of stakeholders – from academia to the private sector – to contribute to the development of large, multi-location datasets.

In “Role of Modelling in International Crop Research: Overview and Some Case Studies,” CGIAR researchers outline the history and basic principles of crop modelling, and describe major theoretical advances and their practical applications by international crop research centers. They also highlight the importance of agri-food systems, which they view as key to meeting global development challenges. “The renewed focus on the systems-level has created significant opportunities for modelers to participant in enhancing the impact of science on developments. However, a coherent approach based on principles of transparency, cooperation and innovation is essential to achieving this.”

The authors call for closer interdisciplinary collaboration to better serve the crop research and development communities through the provision of model-based recommendations which could range from government-level policy development to direct crop management support for resource-poor farmers.

The itsy bitsy spider can make a big impact in agriculture

A new study explores how conservation agriculture in southern Africa supports spider populations and diversity in fields, which could help mitigate pest damage and potentially lead to higher yields for farmers. According to the Food and Agriculture Organization of the United Nations (FAO), herbivorous insects such as aphids, caterpillars and weevils destroy about one fifth of the world’s total crop production each year. Spiders can help keep voracious pests in-check, but conventional farming practices (e.g. tilling, crop residue removal and monoculture) can harm or drastically reduce these beneficial bio-control agents.

There are more than 45,000 identified spider species around the world. From glaciers to tropical rainforests, they inhabit every terrestrial ecosystem on earth. Some can even live in tidal zones, and at least one species inhabits fresh water. While we tend to associate spiders with webs, only about 50 percent of the species catch their prey this way; the rest hunt on plants, on the ground or below it, using a variety of tactics such as stalking, stabbing, crushing – even seduction.

Although spiders have been around for 300 million years, some species are at risk of extinction due to habitat loss and fragmentation. Drastic reductions in vegetation – whether from a new parking lot or a tilled field – removes the food source that attracts their prey. Bare ground exposes their nesting sites and themselves, which makes it harder to hunt and easier to be hunted by birds and small mammals.

At the Chinhoyi University of Technology experimental farm in Zimbabwe, a team of researchers aimed to determine the response of spiders under different agricultural practices. Conventional farmers often prepare their fields for planting by physically breaking up and inverting the top 6-10 inches of soil. This practice of ploughing prepares a fine soil tilth, which makes it easier to plant; it breaks up and buries weeds, and reduces soil compaction to aerate the soil. But tilling also increases topsoil erosion from wind and water. It accelerates soil carbon decomposition, reduces soil water infiltration and disrupts microorganisms living in the soil, including beneficial insects and spiders.

The researchers conducted two experiments over the 2013/2014 and 2014/2015 cropping seasons to see how tilling, crop residue retention (i.e. leaving stalks and post-harvest organic matter in the field), fertilizer application and weeding affected ground- and plant-wandering spider species. They hypothesized that spider abundance and diversity would increase with lower levels of soil disturbance and more plant cover.

The results showed direct seeding into no-till soil increased the abundance of spiders and the diversity of species. Mulching also showed a positive effect. Contrary to their hypotheses and results from temperate regions, the application of fertilizer and intense weeding did not affect the spider community. The researchers attributed this to the difference in climatic conditions (tropical vs. temperate) of this study in southern Africa.

“Often the government’s and farmer’s immediate reaction to a crop pest issue is to apply a pesticide, but we can make use of biological control agents, which may be cheaper and less damaging for the environment,” says Christian Thierfelder, a co-author of the study. Thierfelder is a cropping systems agronomist and conservation agriculture specialist with the International Maize and Wheat Improvement Center (CIMMYT) with long-term experience in sustainable intensification.

“Spiders, ants and beetles all do a really good job with little or no cost to the farmer,” he adds. “For us, it’s quite fascinating to see simple agronomic practices to affect and control crop pests. This also provides new avenues of dealing with the fall armyworm, an invasive species which has devastated crops across the majority of sub-Saharan Africa countries.”

A robust number of studies from Europe, Australia and North America have shown the link between conservation agriculture and biodiversity, but Thierfelder says that research on biodiversity in agronomic systems is relatively new in southern Africa. While the study in Zimbabwe helps fill this gap, more research is needed to show the connection between the abundance of spiders, beetles and ants with the suppression of insect pest activity.

This research was jointly funded by Chinhoyi University of Technology (CUT) and the German Academic Exchange Program (DAAD). The CGIAR Research Program on Maize (MAIZE) supported this study through Christian Thierfelder’s contributions.

Reducing high yield gaps with decision-support apps

Written by Emma Orchardson on January 15, 2019. Posted in Features.

Ethiopia is Africa’s third largest producer of maize, after Nigeria and South Africa. Although the country produces around 6.5 million tons annually, the national average maize yield is relatively low at 3.5 tons compared to the attainable yield of 8.5 tons. This high yield gap — the difference between attainable and actual yields — can be attributed to a number of factors, including crop varieties used, farm management practices, and plant density.

The Taking Maize Agronomy to Scale (TAMASA) project aims to narrow maize yield gaps in Ethiopia, Nigeria and Tanzania through the development and scaling out of decision-support tools, which provide site-specific recommendations based on information held in crop and soil databases collected from each country. These help farmers to make decisions based on more accurate variety and fertilizer recommendations, and can contribute to improving maize production and productivity.

One such tool is Nutrient Expert, a free, interactive computer-based application. It can rapidly provide nutrient recommendations for individual farmers’ fields in the absence of soil-testing data. The tool was developed by the International Plant Nutrition Institute in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA), and research and extension service providers.

In Ethiopia, regional fertilizer recommendations are widely used, but soil fertility management practices can vary greatly from village to village and even between individual farmers. This can make it difficult for farmers or extension agents to receive accurate information tailored specifically to their needs. Nutrient Expert fills this gap by incorporating information on available fertilizer blends and giving customized recommendations for individual fields or larger areas, using information on current farmer practices, field history and local conditions. It can also provide advice on improved crop management practices such as planting density and weeding, thereby helping farmers to maximize net returns on their investment in fertilizer.

Data calibration was based on the results of 700 multi-location nutrient omission trials conducted in major maize production areas in Ethiopia, Nigeria and Tanzania. These trials were designed as a diagnostic tool to establish which macro-nutrients are limiting maize growth and yield, and determine other possible constraints.

In Ethiopia, CIMMYT scientists working for the TAMASA project conducted nutrient omission trials on 88 farmer fields in Jimma, Bako and the Central Rift Valley in 2015 to produce a version of Nutrient Expert suitable for the country. Researchers trialed the app on six maize-belt districts in Oromia the following year, in which Nutrient Expert recommendations were compared with soil-test based and regional ones.

Researchers found that though the app recommended lower amounts of phosphorus and potassium fertilizer, overall maize yields were comparable to those in other test sites. In Ethiopia, this reduction in the use of NPK fertilizer resulted in an investment saving of roughly 80 dollars per hectare.

Results from Nutrient Expert trials in Ethiopia, Nigeria and Tanzania showed improved yields, fertilizer-use efficiency and increased profits, and the app has since been successfully adapted for use in developing fertilizer recommendations that address a wide variety of soil and climatic conditions in each of the target countries.

The World Bank’s 2016 Digital Dividends report states that we are currently “in the midst of the greatest information and communications revolution in human history.” This shifting digital landscape has significant implications for the ways in which stakeholders in the agricultural sector generate, access and use data. Amidst Africa’s burgeoning technology scene, CIMMYT’s TAMASA project demonstrates the transformative power of harnessing ICTs for agricultural development.

CIMMYT celebrates AWARD’s ten years empowering African women in agricultural research

Written by on January 10, 2019. Posted in News.

The International Maize and Wheat Improvement Center’s (CIMMYT) gender team joined African Women in Agricultural Research and Development (AWARD) to celebrate its ten years of empowering women with essential skills and knowledge.

The AWARD program advocates for a more gender-responsive agricultural research ecosystem. This is key in driving a more sustainable and inclusive agricultural growth in Africa.

The tenth anniversary event took place in Nairobi on November 29, 2018. Rahma Adam, Gender and Development Scientist, and Kristie Drucza, Gender and Social Inclusion Researcher, showcased the work that CIMMYT’s gender team has done on maize and wheat-based farming systems, not just in Africa, but globally.

“Our participation at AWARD’s anniversary celebrations was not an end in itself, but rather relevant for other organizations within and outside the CGIAR system to learn from CIMMYT’s gender strategic and inclusive research work and draw lessons from it,” Adam said. “We especially appreciate the work done by AWARD, including the leadership trainings offered to promising young women at academic and research institutions, and at international organizations across Africa and beyond.”

Several researchers at CIMMYT have participated in AWARD’s initiatives, both getting mentorship or training and mentoring fellow scientists, thereby nurturing the next crop of researchers and leaders in agriculture.

“These courses are useful in helping one to strike a balance between being a good researcher and a good leader at the workplace and beyond,” Adam said.

Drucza commented on the leadership training she participated in: “They provide opportunities for leaders (some of whom are heads of research institutes across Africa) to understand common leadership challenges women face, engage in thought-provoking conversations and create lasting networks, among other issues.”

In 2018, Drucza, mentored a gender unit director at the Ethiopian Institute for Agricultural Research (EIAR). “As part of the AWARD program, my mentee attended a leadership development course as well as a scientific writing course. This improved her confidence and skills as a researcher and leader,” Drucza said.

As a beneficiary of the AWARD mentorship program in 2014-2015, Pauline Muindi, a research associate at CIMMYT’s gender unit, honed her communication and public speaking skills, which have proved useful for her work.

“These skills have enabled me to train several seed companies in eastern and southern Africa on the integration of gender in the seed value chains as well as gender integration in the workplace,” she said. Her mentor was a previous AWARD fellow. The program also helped her set realistic yet attainable goals for her career growth. “At CIMMYT, I have an opportunity to learn and gain new experiences, while at the same time build sustainable networks that are important in my professional life.”

The keynote speaker was Ameenah Gurib-Fakim, former president of Mauritius. “Women have a special power to be advocates for themselves and each other. We must become aware of that power and unleash it. Ultimately, it will be for we women to open the doors so that others may live and prosper,” Gurib-Fakim concluded.

Finding the story behind weeds

The main focus of the Sustainable and Resilient Farming Systems Intensification (SRFSI) project is on conservation agriculture technologies. Since farmers may face an increase in weeds after adopting zero-till planters, however, more research is needed about how farmers are dealing with weed.

One of the research objectives of the project is to understand farmers’ knowledge, perception, and practices of conservation agriculture. To this end, researchers are using the Photovoice methodology in Cooch Behar (West Bengal, India), Rongpur (Bangladesh) and Sunsari (Nepal) to collect relevant data on weed management practices.

Photovoice is a visual qualitative research method that allows people to express their perspectives through photographs. Photography can be used for evaluation purposes, through storytelling exercises.

On December 6-7, 2019, field technicians in Bangladesh, India and Nepal participated in a training about this methodology. They learned the rationale of Photovoice, its technical and logistic aspects, as well as the ethical considerations and the need to collect consent forms.

Participants also learned how to take pictures of inter-row cultivation and weeds on the farm, and how to confirm the geolocation of the farm.

Worth a thousand words

Using the Photovoice method, 30 households will be explored, including their labor allocation and decision-making dynamics around the implementation of conservation agriculture practices.

The effectiveness of this approach will emerge as smallholder farmers present their perspectives through photographs accompanied by their narratives.

Activities will be monitored on weekly basis.

The SRFSI project, funded by the Australian Centre for International Agricultural Research (ACIAR) and led by the International Maize and Wheat Improvement Center, is set to improve the productivity, profitability and sustainability of smallholder agriculture in the Eastern Gangetic Plains of Bangladesh, India and Nepal, by promoting sustainable intensification based on conservation agriculture technologies.
