Building a better future

The ongoing COVID-19 pandemic has wreaked havoc on institutions, systems, communities and individuals while, at the same time, laying bare structural inequalities — including gender disparities.  

Common gender norms mean that women are on the frontline collecting water, fuel, fodder and provide care work, both in the home and through formal employment, where 70% of global healthcare workers are women. Additionally, the sectors that women often rely on for income and food security are stressed by border closures, restricted transportation and social distancing guidelines. 

Women are also instrumental in the fight against shocks, including the facilitation of better COVID-19 adaptation strategies. In India women’s self-help groups are helping to feed people, provide health information and create face masks. Initiatives in Senegal and the Democratic Republic of Congo place women at the center of efforts to combat the virus. At the national level, initial research suggests that women leaders have managed the pandemic better, recording fewer infections and a lower death rate. 

This dichotomy, one where women are essential for combatting system shocks while simultaneously underrepresented in decision-making spaces, illustrates why gender research, especially research that aims to understand women’s roles as active agents of change, is essential. Gender research supports more equitable outcomes during and post-crisis, while helping to build more resilient systems.  

The International Day of Rural Women is an opportunity to celebrate the importance of women for the future of rural communities, while also examining how gender research, like that undertaken by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), plays an instrumental role in supporting them.  

Gender and the climate crisis

Gender research is also important in combatting another crisis we are facing — the climate crisis. For example, climate-smart agriculture (CSA) has the potential to reduce agriculture’s gender gap. To close the gap, women must be included in the design of CSA interventions, with special attention on how CSA technologies can reduce or add to the agriculture workloads that women face. Research on dairy intensification from Kenya points to the complicated role gender plays in household decisions about feeding livestock concentrate or whether milk is sold in formal or informal markets. 

The Scaling-Out Climate-Smart Village Program in the Vulnerable Areas of Indo-Gangetic Plains of India includes a gender integration for inclusive adaptation to climate risks component. Implemented in the Indian states of Bihar, Madhya Pradesh and Uttar Pradesh, it promotes technologies that reduce women’s agriculture-related labor while helping women develop their leadership and entrepreneurial skills. 

Farmers can also benefit from climate information services, which allows them to plan and prepare for changing weather. Once again, access to technology and gender norms play a role in how climate information is accessed, what type of information is needed, and how it is used. For example, when COVID-19 prevented farmers in Somotillo, Nicaragua from holding in-person meetings, they  turned to online tools. By connecting with women’s groups and considering women’s climate information needs, researchers can help create services that benefit both men and women.  

At the policy level, gender mainstreaming allows governments to effectively — and inclusively — combat climate change. However, developing and implementing these policies requires gender analysis, the creation of gender tools, data collection, analysis, the development of gender indicators, and gender budgeting as research from Uganda and Tanzania illustrates. 

These examples are just a few avenues through which gender research influences the uptake of technology, policy and information access. System shocks are inevitable and their frequency and severity are likely to increase due to climate change. Given this reality, men’s and women’s needs and perspectives must be considered in research activities so that climate solutions are inclusive, equitable and effective.

Farming has often been quoted as one of the noblest professions, shouldering the responsibility of feeding the world; yet it has been globally identified as one of the most perilous industries associated with a high vulnerability rate. Crop insurance has been established worldwide to provide social protection to farmers and reduce their vulnerability. While the emergence of crop insurance schemes around the world indicates commitment to secure the livelihoods of farmers, they often lack accurate seasonal crop growth monitoring and timely yield loss estimation, making the authentication of crop insurance claims more challenging.

Crop loss assessments are often done via crop cutting experiments (CCEs). However, these can suffer from human error and moral hazard. The experiments also require significant capital and human resources, and need to be carried out simultaneously, in a limited period of time. This often leads to inadequate and delayed claim payment, high premium rates, and poor execution of crop insurance schemes.

With technological advancements and availability, crop growth monitoring and productivity assessment can not only be more accurate and efficient but also less resource-intensive. Readily available data and technology, such as detailed weather data, remote sensing, modeling and big data analytics can be instrumental in further improving crop insurance mechanisms. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has developed a Crop-loss Assessment Monitor (CAM) tool as an integrated solution that uses technologies to improve loss assessment and make crop insurance more efficient.

The Crop-loss Assessment Monitor (CAM) tool

The CAM tool integrates multiple input data and methods for crop loss assessment at multiple times in the season. It uses different models for loss assessment depending on the time or stage in the season. To ensure user-friendliness, the tool was developed with a simple, easy-to-use interface and produces outputs customized for policy and risk management agencies. It uses freely available R libraries and does not require specific software installations and high-power processing engines, which in general are a prerequisite to process large gridded satellite data.

CAM provides a form-based user-interface to carry out the analysis. The user can log in and undertake analysis using multiple methods for a specified region and time. The tool allows users to choose between area-based yield insurance and weather-based index insurance. For insurance analysis, scheme details like sum insured and calamity years can be specified for calculation of threshold yields, premiums and claims.

CAM also includes tabs that provide ‘deviation in the weather’ and ‘deviation in satellite vegetation indices’ to help monitor crop conditions every fortnight. The tool also allows users to identify the model agreement between the four different methods for loss assessment, which strengthens the confidence levels in loss assessments, and related insurance analytics.

A single integrated framework

The tool combines agro-meteorological statistical analysis, crop simulation modelling and optimization techniques, and employs near real-time monitoring by using publicly available satellite products. It is also equipped to capture yield variability.

Highlighting the importance of this tool Dr. Pramod Aggarwal, lead author of the paper and CCAFS Asia Program Leader, notes that “assimilating relevant technologies into a single integrated framework is a good way to determine crop losses. Its deployment can assist in multi-stage loss assessment and thus provide farmers with immediate relief for sowing failure, prevented sowing and mid-season adversity apart from final crop loss assessment.”

The tool addresses three major challenges faced by existing crop insurance schemes; more efficient weather indices, timely estimate of loss assessment and improved contract design. As the tool readily uses freely available technology and data, it requires less capital and human resource compared to crop cutting experiments for crop loss assessment. This tool offers a robust mechanism that further reduces the chances of human errors, and makes the process more transparent, robust and reliable. Therefore, it enables timely relief for farmers facing challenges such as sowing failure, prevented sowing and mid-season adversity.

Ever-increasing emissions of greenhouse gases (GHG) is a global concern due to the association of high atmospheric GHG concentrations with global warming and climate change. A large and growing body of evidence predicts that this would further have a multifaceted impact on the human population, especially the poor and vulnerable groups, further exacerbating their vulnerabilities.

But what about crops? Plants use carbon dioxide (CO2)—one of the most abundant GHGs, for photosynthesis. So shouldn’t an increase in atmospheric carbon dioxide aid crops to flourish? A counter-argument to this would be that at the same time there would be changes in other factors such as a change in precipitation rate, frequency and intensity of rains, among others, which might negatively impact crop production. So, how exactly would climatic variations impact the yield and productivity of crops? These are some of the questions that have been a global concern. Many studies have researched this, employing varied approaches such as systems biology, physiology and crop modelling. However, unprecedented changes in climatic conditions still pose uncertainties on the impacts on crops.

Recent research by an interdisciplinary team of scientists from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the CGIAR Research Program on Climate Chanage, Agriculture and Food Security (CCAFS)-Africa and CCAFS-Asia aspires to answer some of these questions. As part of this research, they have compiled recent progress made in the physiological and molecular attributes in plants, with special emphasis on legumes under elevated CO2 conditions in a climate change scenario. The study proposes a strategic research framework for crop improvement that integrates genomics, systems biology, physiology and crop modelling approaches to cope with the changing climate. Some of the prime results of the study are as follows:

1. Major physiological and biochemical alterations in legumes triggered by elevated CO2

A range of physiological and biochemical alterations take place in plants exposed to elevated CO2. In the case of legumes, elevated atmospheric CO2 concentrations also affect the nutritional quality and nodulation, causes changes in rhizosphere and Biological Nitrogen Fixation (BNF), among others. Studies have shown that elevated CO2 would stimulate plant growth under nitrogen-sufficient conditions, but under nitrogen-limited conditions, it may have the detrimental effect of reducing plant growth by altering its primary metabolism. The anatomical differences between C3 and C4 plants (plants with C3 and C4 photosynthetic pathways) and their different ways of sequestering carbon (removing carbon dioxide from the atmosphere), have been an area of interest for climate scientists. Elevated CO2 combined with limited nitrogen may also promote biological ageing (senescence) rates as observed in flag leaves of rice and wheat. Studies also show that a higher level of carbon dioxide increases senescence rate in legumes.

2. Impact of elevated carbon-dioxide interaction with other abiotic stresses

As mentioned earlier, CO2 is not the only factor that is impacting plant growth, it is dependent on other environmental factors such as water deficit stress and temperature, among others. Thus, these factors also need to be considered in combination with the atmospheric concentration. Studies have reported that elevated CO2 induced a decrease (of 10%) in evaporation rates in both C3 and C4 plants. This caused an increase in canopy temperature (0.7 °C) coupled with a 19% yield increase in C3 crops. There is evidence that an increase in CO2 has also phased down the effect of oxidative stress. Though, there is limited literature available about the impact of elevated carbon dioxide keeping into consideration the drought and heat responses of various crops.

3. Elevated carbon dioxide and its interaction with biotic stress-altered pathogen aggravation and virulence

The changing climate has affected pest-crop dynamics with more frequent outbreaks and changed the geographical distribution of pests, posing an economic threat to crops. Sometimes, other abiotic stresses like drought could increase fungal virulence as reported in drought-tolerant peanut and Aspergillus interaction. However, a combined interaction is not always additive as both unique and common responses have been observed. Increased CO2 causes greater photosynthate availability, but reduced foliage quality along with an increased concentration of plant defensive compounds after a pest infestation. This, in turn, affects insect feeding and increases disease incidence and predator parasitism interactions.

4. Molecular interventions for crop improvement under elevated carbon-dioxide

While elevated CO2 may cause greater photosynthate availability, the interaction of elevated CO2 with mentioned biotic and abiotic stresses calls for the development of climate change ready crop varieties. Thus, genomics assisted breeding along with other modern approaches can be very powerful tools to develop superior varieties, to de-risk the existing food system. This transformative approach towards the production of plants and crops would be instrumental in sustainably ensuring food security.

An integrated research framework for the future

The discussion and evidence presented illustrate that the effect of elevated CO2 under a changing climate scenario is multifaceted and aggravated by the overlapping interaction of stressors. The notion that CO2 has beneficial effects in terms of increased productivity is now being questioned since the photosynthetic fertilization effect is short term and often not time-tested for major crop species. The IPCC 2018 special report highlights several policy-level approaches that are aimed at limiting greenhouse gas emission. The scientific community needs to be prepared with suitable research outcomes to cope with the effects of elevated atmospheric CO2 levels. In this regard, an integrated framework combining different biological disciplines has been proposed by the team (Fig. 1).

While significant advances have been made in crop genomics, systems biology and genomics-assisted breeding, the success of trait dissection and trait deployment is very much dependent on the quality and precision of phenotyping. Recent advances in plant phenotyping using high throughput phenotyping tools have revolutionized the uptake of phenotype and allelic information in a more precise and robust way and complemented high throughput genomic resources

In the opinion of the authors of the publication, an integrated research framework that includes genomics/ systems biology and phenomics together with crop modelling would result in faster data-driven advances for understanding the optimal GxExM (genotype x environment x management) scenarios for current and projected climates. Interdisciplinary approaches as has been done through the Climate-Smart Village approach, are key to graduating from a descriptive level to an improved quantitative and process-level understanding of sustainable crop productivity.

Ethiopia puts in place strategies to ensure food availability amid COVID-19 crisis

Kindie Tesfaye (CIMMYT) appears on Fana Television.

As the COVID-19 pandemic continues to widen, its effects on the agriculture sector are also becoming apparent. In countries like Ethiopia, where farming is the backbone of the nation’s economy, early preparation can help mitigate adverse effects.

Recently, Fana Broadcasting Corporate (Fana Television) organized a panel discussion on how the Ethiopian government and its partners are responding to this crisis. Analyzing this topic were Kindie Tesfaye from the International Maize and Wheat Improvement Center (CIMMYT), Mandefro Negussi of the Ethiopian Institute of Agricultural Research (EIAR) and Esayas Lemma from the Ministry of Agriculture.

The panelists highlighted Ethiopia’s readiness in response to COVID-19. The country established a team from various institutions to work on strategies and to ensure no further food shortages occur due to the pandemic. The strategy involves the continuation of activity already started during the Bleg season — short rainy season — and the preparation for the Meher season — long rainy season — to be complemented by food production through irrigation systems during the dry season, if the crisis continues beyond September 2020.

Tesfaye indicated that CIMMYT continues to work at the national and regional levels as before, and is represented in the advisory team. One of the activities underway, he said, is the plan to use the Agro-Climate Advisory Platform to disseminate COVID-19 related information to extension agents and farmers.

Panelists agreed that the pandemic will also impact the Ethiopian farming system, which is performed collectively and relies heavily on human labor. To minimize the spread of the virus, physical distancing is highly advisable. Digital media, social media and megaphones will be used to reach out to extension agents and farmers and encourage them to apply all the necessary precaution measures while on duty. Training will also continue through digital means as face to face meetings will not be possible.

Could coronavirus drive farmers to adopt sustainable practices in India’s breadbasket?

June marks the start of the rice growing season in India’s breadbasket but on the quiet fields of Haryana and Punjab you wouldn’t know it.

Usually the northwestern Indian states are teeming with migrant laborers working to transplant rice paddies. However, the government’s swift COVID-19 lockdown measures in late March triggered reverse migration, with an estimated 1 million laborers returning to their home states.

The lack of migrant workers has raised alarms for the labor-dependent rice-wheat farms that feed the nation. Healthy harvests are driven by timely transplanting of rice and, consequently, by the timely sowing of the succeeding wheat crop in rotation.

Without political support for alternative farming practices, crop losses from COVID-19 labor disruptions could reach $1.5 billion and significantly diminish the country’s grain reserves, researchers from the International Maize and Wheat Improvement Center (CIMMYT) warned.

Researchers also fear delayed rice transplanting could encourage unsustainable residue burning as farmers rush to clear land in the short window between rice harvest and wheat sowing. Increased burning in the fall will exacerbate the COVID-19 health risk by contributing to the blanket of thick air pollution that covers much of northwest India, including the densely populated capital region of New Delhi.

Both farmers and politicians are showing increased interest in farm mechanization and crop diversification as they respond to COVID-19 disruptions, said M.L. Jat, a CIMMYT scientist who coordinates sustainable intensification programs in northwestern India.

“Farmers know the time of planting wheat is extremely important for productivity. To avoid production losses and smog-inducing residue burning, alternative farm practices and technologies must be scaled up now,” Jat said.

The time it takes to manually transplant rice paddies is a particular worry. Manual transplanting accounts for 95% of rice grown in the northwestern regions. Rice seedlings grown in a nursery are pulled and transplanted into puddled and leveled fields — a process that takes up to 30 person-days per hectare, making it highly dependent on the availability of migrant laborers.

Even before COVID-19, a lack of labor was costing rice-wheat productivity and encouraging burning practices that contribute to India’s air pollution crisis, said CIMMYT scientist Balwinder Singh.

“Mechanized sowing and harvesting has been growing in recent years. The COVID-19 labor shortage presents a unique opportunity for policymakers to prioritize productive and environmentally-friendly farming practices as long term solutions,” Singh said.

Sustainable practices to cope with labor bottlenecks

CIMMYT researchers are working with national and state governments to get information and technologies to farmers, however, there are significant challenges to bringing solutions to scale in the very near term, Singh explained.

There is no silver bullet in the short term. However, researchers have outlined immediate and mid-term strategies to ensure crop productivity while avoiding residue burning:

Delayed or staggered nursery sowing of rice:  By delaying nursery sowing to match delays in transplanting, yield potential can be conserved for rice. Any delay in transplanting rice due to labor shortage can reduce the productivity of seedlings. Seedling age at transplanting is an important factor for optimum growth and yield.

“Matching nursery sowing to meet delayed transplanting dates is an immediate action that farmers can take to ensure crop productivity in the short term. However, it’s important policymakers prioritize technologies, such as direct seeders, that contribute to long term solutions,” Singh said.

Direct drilling of wheat using the Happy Seeder: Direct seeding of wheat into rice residues using the Happy Seeder, a mechanized harvesting combine, can reduce the turnaround time between rice harvest and wheat sowing, potentially eliminating the temptation to burn residues.

“Identifying the areas with delayed transplanting well in advance should be a priority for effectively targeting the direct drilling of wheat using Happy Seeders,” said Jat. The average farmer who uses the Happy Seeder can generate up to 20% more profits than those who burn their fields, he explained. “Incentivizing farmers through a direct benefit transfer payment to adopt ‘no burn’ practices may help accelerate transitions.”

Directly sown rice: Timely planting of rice can also be achieved by adopting dry direct seeding of rice using mechanized seed-cum-fertilizer planters. In addition to reducing the labor requirement for crop establishment, dry direct seeding allows earlier rice planting due to its lower water requirement for establishment. Direct-seeded rice also matures earlier than puddled transplanted rice. Thus, earlier harvesting improves the chance to sow wheat on time.

“CIMMYT researchers are working with the local mechanical engineers on rolling out simple tweaks to enable the Happy Seeder to be used for direct rice seeding. The existing availability of Happy Seeders in the region will improve the speed direct rice sowing can be adopted,” Jat said.

Crop diversification with maize: Replacing rice with maize in the monsoon season is another option to alleviate the potential shortage of agricultural labor due to COVID-19, as the practice of establishing maize by machine is already common.

“Research evidence generated over the past decade demonstrates that maize along with modern agronomic management practices can provide a profitable and sustainable alternative to rice,” Jat explained. “The diversification of rice with maize can potentially contribute to sustainability that includes conserving groundwater, improving soil health and reducing air pollution through eliminating residue burning.”

Getting innovations into farmers’ fields

Rapid policy decisions by national and state governments on facilitating more mechanized operations in labor-intensive rice-wheat production regions will address labor availability issues while contributing to productivity enhancement of succeeding wheat crop in rotation, as well as overall system sustainability, said ICAR’s deputy director general for agricultural extension, AK Singh.

The government is providing advisories to farmers through multiple levels of communications, including extension services, messaging services and farmer collectives to raise awareness and encourage adoption.

Moving toward mechanization and crop diversity should not be viewed as a quick fix to COVID-19 related labor shortages, but as the foundation for long-term policies that help India in achieving the UN Sustainable Development Goals, said ICAR’s deputy director general for Natural Research Management, SK Chaudhari.

“Policies encouraging farming practices that save resources and protect the environment will improve long term productivity of the nation,” he said.

Northwestern India is home to millions of smallholder farmers making it a breadbasket for grain staples. Since giving birth to the Green Revolution, the region has continued to increase its food production through rice and wheat farming providing bulk of food to the country.

This high production has not come without shortfalls, different problems like a lowering water table, scarcity of labor during peak periods, deteriorating soil health, and air pollution from crop residue burning demands some alternative methods to sustain productivity as well as natural resources.

Big data analytics for climate-smart agricultural practices in South Asia (Big Data2 CSA)

Heterogeneity in soils, hydrology, climate, and rapid changes in rural economies including fluctuating prices, aging and declining labor forces, agricultural feminization, and uneven market access are among the many factors that constrain climate-smart agriculture (CSA) in South Asia’s cereal-based farming systems.

Most previous research on CSA has employed manipulative experiments analyzing agronomic variables, or survey data from project-driven initiatives. However, this can obscure the identification of relevant factors limiting CSA, leading to inappropriate extension, policy, and inadequate institutional alignments to address and overcome limitations. Alternative big data approaches utilizing heterogeneous datasets remain insufficiently explored, though they can represent a powerful alternative source of technology and management practice performance information.

In partnership with national research systems and the private sector in Bangladesh, India and Nepal, Big data analytics for climate-smart agricultural practices in South Asia (Big Data2 CSA) is developing digital data collection systems to crowdsource, data-mine and interpret a wide variety of primary agronomic management and socioeconomic data from tens of thousands of smallholder rice and wheat farmers.

The project team analyzes these data by stacking them with spatially-explicit secondary environmental, climatic and remotely sensed data products, after which data mining and machine learning techniques are used to identify key factors contributing to patterns in yield, profitability, greenhouse gas emissions intensity and resilience.

These approaches however must be practical in order for them to be useful in agricultural development and policy. As such, the project’s analytical results will be represented through interactive web-based dashboards, with gender-appropriate crop management advisories deployed through interactive voice recognition technologies to farmers in Bangladesh, India and Nepal at a large-scale. Big Data2 CSA is supported by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) Flagship 2 on Climate-Smart Technologies and Practices.

Objectives

  • Develop ICT tools enabling digital collection of crop management data and a cloud-based database that can be managed by next-users
  • Support advanced degree-level students to engage in field and data science research
  • Create a digital data collection platform enabling crowd sourcing of crop management information to evaluate contributions to CSA
  • Create interactive and customizable web-based dashboards presenting post-season research results and providing CSA management recommendations
  • Organize CSA and big data policy briefings on mainstreaming processes and policy workshops

A less risky business

Because of unpredictable climate conditions, agricultural production in Ethiopia faces uncertainties during both the growing and harvesting seasons. The risk and uncertainty are bigger for smallholder farmers, as they can’t protect themselves from climate-related asset losses. Access to insurance schemes, climate information and other tools could help to minimize climate risks for smallholder farmers.

A new collaborative project launched in Ethiopia aims to reduce agricultural investment risk. The Capacitating African Stakeholders with Climate Advisories and Insurance Development (CASCAID-II) project builds on learnings from the CASCAID-I project in West Africa. It will target Ethiopia, Ghana and Senegal, focusing not only on smallholder farmers but on the food value chain as a whole. In a context of increasing integration of farmers into urban markets, the project will improve agricultural productivity, food security and profitability of agricultural enterprises.

The International Maize and Wheat Improvement Center (CIMMYT) will partner with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the University of Florida, with the support of the CGIAR research program on Climate Change, Agriculture and Food Security (CCAFS).

Physical and digital tools across the value chain

In October 2019, thirty partners gathered for the CASCAID-II project launch and meeting in Addis Ababa, Ethiopia. They agreed on the project goals, a set of priority research questions and a schedule of activities for the next two years.

Partners also reviewed the tools that could be used to deliver climate advisories and agricultural insurance products, ensuring that all the actors in the value chain are engaged from the start. Team members aim to embed services in existing physical and digital (“phygital”) data infrastructures and to collect user feedback, so performance can be improved. Users will be segmented according to advanced socioeconomic and agro-ecological factors, so they can be targeted more efficiently with appropriate services and climate-smart agriculture options. The project will draw on real-time and multi-scale yield forecasting for better preparedness and decision-making.

Project partners agreed to start with the CCAFS Regional Agricultural Forecasting Tool (CRAFT) for sub-national yield forecasting in Ethiopia and to develop climate advisories and insurance services in line with the needs of the Ministry of Agriculture.

Precise data from scientists to farmers

In a related development, Ethiopia recently launched a digital agro-climate advisory platform, which offers great potential to improve farmers’ management of climate-induced risks, facilitate technology adoption and improve livelihoods.

Speaking at the platform’s launch ceremony, Eyasu Abraha, advisor to the Minister of Agriculture, thanked development partners for supporting the establishment of the platform in the timely move towards digitalization and use of precise data.

The platform incorporates location-specific climate information, as well as soil- and crop-specific best-bet agronomic management recommendations for farmers, development agents and extension officers. It automates crop-climate modeling and uses technologies such as text messaging, interactive voice response (IVRS) and smartphone apps for dissemination.

Agricultural research is entering a new age in Bangladesh. The days, months and years it takes to collect farm data with a clipboard, paper and pen are nearing their end.

Electronic smartphones and tablets are gaining ground, used by researchers, extension workers and farmers to revolutionize the efficiency of data collection and provide advice on best-bet practices to build resilient farming systems that stand up to climate change.

Digital data collection tools are crucial in today’s ‘big data’ driven agricultural research world and are fundamentally shifting the speed and accuracy of agricultural research, said Timothy Krupnik, Senior Scientist and Systems Agronomist at the International Maize and Wheat Improvement Center (CIMMYT).

“Easy-to-use data collection tools can be made available on electronic tablets for surveys. These allow extension workers to collect data from the farm and share it instantaneously with researchers,” he said.

“These tools allow the regular and rapid collection of data from farmers, meaning that researchers and extension workers can get more information than they would alone in a much quicker time frame.”

“This provides a better picture of the challenges farmers have, and once data are analyzed, we can more easily develop tailored solutions to farmers’ problems,” Krupnik explained.

Through the USAID and Bill and Melinda Gates supported Cereal Systems Initiative for South Asia (CSISA), and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) supported Big Data Analytics for Climate-Smart Agriculture in South Asia projects, 125 Department of Agricultural Extension (DAE) agents were trained throughout Bangladesh to use tablets to gather agronomic information from rice and wheat farmers.

It is the first time extension workers have been involved in data collection in the country. Since the pilot began in late 2019, extension workers have collected data from over 5,000 farmers, with detailed information on climate responses, including the management of soil, water and variety use to understand what drives productivity. The DAE is enthused about learning from the data, and plans to collect information from 7,000 more farmers in 2020.

Bangladesh’s DAE is directly benefiting through partnerships with expert national and international researchers developing systems to efficiently collect and analyze massive amounts of data to generate relevant climate-smart recommendations for farmers, said the department Director General Dr. M. Abdul Muyeed.

For the first time widespread monitoring examines how farmers are coping with climate stresses, and agronomic data are being used to estimate greenhouse gas emissions from thousands of individual farmers. This research and extension partnership aims at identifying ways to mitigate and adapt to climate change, he explained.

“This work will strengthen our ability to generate agriculturally relevant information and increase the climate resilience of smallholder farmers in Bangladesh,” Dr. Muyeed said.

Next-gen big data analysis produces best-bet agricultural practices

“By obtaining big datasets such as these, we are now using innovative research methods and artificial intelligence (AI) to examine patterns in productivity, the climate resilience of cropping practices, and greenhouse gas emissions. Our aim is to develop and recommend improved agricultural practices that are proven to increase yields and profitability,” said Krupknik.

The surveys can also be used to evaluate on-farm tests of agricultural technologies, inform need-based training programs, serve local knowledge centers and support the marketing of locally relevant agricultural technologies, he explained.

“Collecting farm-specific data on greenhouse gas emissions caused by agriculture and recording its causes is a great step to develop strategies to reduce agriculture’s contribution to climate change,” added Krupnik.

New publications: Optimum nitrogen fertilizer rates for rice and wheat in the Indo-Gangetic Plains of India

New research by an international team of scientists, including International Maize and Wheat Improvement Center (CIMMYT) agricultural systems and climate change scientist Tek Sapkota, has identified the optimum rates of nitrogen fertilizer application for rice and wheat crops in the Indo-Gangetic Plains of India.

By measuring crop yield and nitrous oxide (N2O) fluxes over two years, Sapkota and his colleagues reported that the optimum rate of N fertilizer for rice is between 120 and 200 kg per hectare, and between 50 and 185 kg per hectare for wheat. The results of the study have the potential to save farmer’s money and minimize dangerous greenhouse gas emissions while maintaining crop productivity.

Nitrous oxide, one of the most important greenhouse gases in the earth’s atmosphere, is responsible for ozone depletion and global climate change, and has a global warming potential 265 times that of carbon dioxide (CO2).

Research has shown that agricultural soils account for around 60% of global nitrous oxide emissions. These emissions are directly related to the application of nitrogen fertilizers to croplands. While these fertilizers help crop yields, studies show that only about one third of the applied nitrogen is actually used by crops. The rest is released as nitrous oxide or seeps into waterways, causing harmful algal blooms.

In India, the total consumption of nitrogen fertilizer is about 17 million tons — expected to rise to 24 million tons by 2030 to feed a growing population. Nitrous oxide emissions will rise along with it if farmers do not minimize their fertilizer use and manage application more efficiently. What’s more, farmers receive a higher subsidy for nitrogen fertilizer — a policy that leads farmers to apply more fertilizer than the recommended dose.

Measured methods

The study, led by Sapkota, estimated the rate of nitrogen fertilizer application with the most economically optimum yield and minimum environmental footprint. Applying more fertilizer than this would be a waste of farmer’s money and cause unnecessary harm to the environment.

Researchers measured crop yield and nitrous oxide fluxes for two wheat seasons and one rice season from 2014 to 2016.  The scientists found that nitrogen fertilization rate clearly influenced daily and cumulative soil nitrous oxide emissions in wheat and rice for both years. Nitrous oxide emissions were higher in both wheat and rice in the nitrogen-fertilized plots than in the control plots.

Using statistical methods, the researchers were able to measure the relationship between crop productivity, nitrogen rate and emissions intensity, in both rice and wheat. This gave them the optimum rate of nitrogen fertilizer application.

This work was carried out by International Maize and Wheat Improvement Center (CIMMYT) and implemented as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), with support from the CGIAR Trust Fund and through bilateral funding agreements.

What is conservation agriculture?

If not practiced sustainably, agriculture can have a toll on the environment, produce greenhouse gases and contribute to climate change. However, sustainable farming methods can do the opposite — increase resilience to climate change, protect biodiversity and sustainably use natural resources.

One of these methods is conservation agriculture.

Conservation agriculture conserves natural resources, biodiversity and labor. It increases available soil water, reduces heat and drought stress, and builds up soil health in the longer term.

What are the principles of conservation agriculture?

Conservation agriculture is based on the interrelated principles of minimal mechanical soil disturbance, permanent soil cover with living or dead plant material, and crop diversification through rotation or intercropping. It helps farmers to maintain and boost yields and increase profits, while reversing land degradation, protecting the environment and responding to growing challenges of climate change.

To reduce soil disturbance, farmers practice zero-tillage farming, which allows direct planting without plowing or preparing the soil. The farmer seeds directly through surface residues of the previous crop.

Zero tillage is combined with intercropping and crop rotation, which means either growing two or more crops at the same time on the same piece of land, or growing two different crops on the same land in a sequential manner. These are also core principles of sustainable intensification.

How is conservation agriculture different from sustainable intensification?

Sustainable intensification is a process to increase agriculture yields without adverse impacts on the environment, taking the whole ecosystem into consideration. It aims for the same goals as conservation agriculture.

Conservation agriculture practices lead to or enable sustainable intensification.

What are the benefits and challenges of conservation agriculture?       

Zero-tillage farming with residue cover saves irrigation water, gradually increases soil organic matter and suppresses weeds, as well as reduces costs of machinery, fuel and time associated with tilling. Leaving the soil undisturbed increases water infiltration, holds soil moisture and helps to prevent topsoil erosion. Conservation agriculture enhances water intake that allows for more stable yields in the midst of weather extremes exacerbated by climate change.

While conservation agriculture provides many benefits for farmers and the environment, farmers can face constraints to adopt these practices. Wetlands or soils with poor drainage can make adoption challenging. When crop residues are limited, farmers tend to use them for fodder first, so there might not be enough residues for the soil cover. To initiate conservation agriculture, appropriate seeders are necessary, and these may not be available or affordable to all farmers. Conservation agriculture is also knowledge intensive and not all farmers may have access to the knowledge and training required on how to practice conservation agriculture. Finally, conservation agriculture increases yields over time but farmers may not see yield benefits immediately.

However, innovations, adapted research and new technologies are helping farmers to overcome these challenges and facilitate the adoption of conservation agriculture.

How did conservation agriculture originate?

The term “conservation agriculture” was coined in the 1990s, but the idea to minimize soil disturbance has its origins in the 1930s, during the Dust Bowl in the United States of America.

CIMMYT pioneered no-till training programs and trials in the 1970s, in maize and wheat systems in Latin America. In the 1980s this technique was also used in agronomy projects in South Asia.

CIMMYT began work with conservation agriculture in Latin America and South Asia in the 1990s and in Africa in the early 2000s. Today, these efforts have been scaled up and conservation agriculture principles have been incorporated into projects such as CSISA, FACASI, MasAgro, SIMLESA, and SRFSI.

Farmers worldwide are increasingly adopting conservation agriculture. In the 2015/16 season, conservation agriculture was practiced on about 180 mega hectares of cropland globally, about 12.5% of the total global cropland — 69% more than in the 2008/2009 season.

Is conservation agriculture organic?

Conservation agriculture and organic farming both maintain a balance between agriculture and resources, use crop rotation, and protect the soil’s organic matter. However, the main difference between these two types of farming is that organic farmers use a plow or soil tillage, while farmers who practice conservation agriculture use natural principles and do not till the soil. Organic farmers apply tillage to remove weeds without using inorganic fertilizers.

Conservation agriculture farmers, on the other hand, use a permanent soil cover and plant seeds through this layer. They may initially use inorganic fertilizers to manage weeds, especially in soils with low fertility. Over time, the use of agrichemicals may be reduced or slowly phased out.

How does conservation agriculture differ from climate-smart agriculture?

While conservation agriculture and climate-smart agriculture are similar, their purposes are different. Conservation agriculture aims to sustainably intensify smallholder farming systems and have a positive effect on the environment using natural processes. It helps farmers to adapt to and increase profits in spite of climate risks.

Climate-smart agriculture aims to adapt to and mitigate the effects of climate change by sequestering soil carbon and reducing greenhouse gas emissions, and finally increase productivity and profitability of farming systems to ensure farmers’ livelihoods and food security in a changing climate. Conservation agriculture systems can be considered climate-smart as they deliver on the objectives of climate-smart agriculture.

A wake-up call for the fertilizer industry

When you hear the words ‘plant nutrition’ or ‘fertilizer’, do you think of sustainability?

Many might not but the recent gathering of plant nutrition experts in Versailles at the High Level Forum on Sustainable Plant Nutrition might indicate that the tide is turning.

“This event is a first of its kind. Here you have the fertilizer industry, which is relatively conservative, and yet there are speakers such as Mostafa Terrab of the OCP Group or Svein Tore Holsether of Yara who are pushing this future agenda,” said Bruce Campbell, Director of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).

“If I was from the fertilizer industry, I would really wake up, as perhaps is happening with some companies. If you look at the airlines industry, you see some super visionary players and others who are not. I feel that there could be players in this group who could be as visionary: looking at cutting down the energy inputs into fertilizer production, working together with governments to reform subsidies that promote over-fertilization, working towards precision fertilizer application. If the fertilizer industry wants to gain the trust of a more and more discerning public, then they need to show climate leadership,” Campbell remarked.

The right time and place

Although fertilizer use revolutionized agriculture and allowed farmers to grow better crops on less land, plant nutrients are often vilified because of the negative environmental impact caused by their improper use.

For this reason, experts often speak of the 4R stewardship principles of fertilizer: right fertilizer source, at the right rate, at the right time, and in the right place.

“The industry needs solid science to back up agricultural technology solutions in the realms of both nutrient and water management. Regarding the right placement, right time and the right quantity of fertilizer, mechanization solutions — such as direct seeders, which place fertilizer close to the seed — can really increase nutrient use efficiency and improve plant early vigor. Together with a wide range of partners, CIMMYT has been using these across smallholder systems of Asia, Africa and Latin America,” highlighted Martin Kropff, Director General of the International Maize and Wheat Improvement Center (CIMMYT), during one of the panel discussions.

In order to scale up the most relevant scientific findings and extension efforts, the focus should be on using available fertilizers better. This goes hand in hand with better management of organic matter and soils. There is a human element too: farmers’ efficiency could be improved with better advice especially targeted at extension offices or service providers.

S for sustainability

In order to identify the missing link of sustainability, just a day before the launch of the forum, the International Fertilizer Association (IFA) created a new Scientific Panel on Responsible Plant Nutrition. This group of international experts will provide objective knowledge and assessments for the fertilizer industry and other stakeholders to develop a more responsible plant nutrition system.

Bruno GĂ©rard, Director of CIMMYT’s Sustainable Intensification research program and a member of the panel, spoke about CIMMYT’s unique selling proposition. “CIMMYT has a significant research agenda and experience in better nutrient management in wheat- and maize-based systems. In regions such as South Asia, the challenge is to produce more or the same with less and better fertilizers through improved management practices. Instead in Sub-Saharan Africa, the focus is on giving better access and knowledge so that farmers can produce more with adequate fertilizer inputs.”

Being part of the panel will give CIMMYT the opportunity to better link up with the fertilizer industry and contribute to improved fertilizer use in term of profitability, yield stability and risk, accessibility but also — from an environmental perspective — minimize the footprint of fertilizer through better agronomic practices and management.

The High Level Forum on Plant Nutrition took place on November 18-20, 2019, in Versailles, France.

Agricultural solutions to tackle humanity’s climate crisis

More than 11,000 scientists signed on to a recent report showing that planet Earth is facing a climate emergency and the United Nations warned that the world is on course for a 3.2 degree spike by 2100, even if 2015 Paris Agreement commitments are met.

Agriculture, forestry, and land-use change are implicated in roughly a quarter of global greenhouse gas emissions.

Agriculture also offers opportunities to mitigate climate change and to help farmers — particularly smallholders in developing and emerging economies who have been hardest hit by hot weather and reduced, more erratic rainfall.

Most of CIMMYT’s work relates to climate change, helping farmers adapt to shocks while meeting the rising demand for food and, where possible, reducing emissions.

Climate-resilient crops and farming practices

53 million people are benefiting from drought-tolerant maize. Drought-tolerant maize varieties developed using conventional breeding provide at least 25% more grain than other varieties in dry conditions in sub-Saharan Africa — this represents as much as 1 ton per hectare more grain on average. These varieties are now grown on nearly 2.5 million hectares, benefiting an estimated 6 million households or 53 million people in the continent. One study shows that drought-tolerant maize can provide farming families in Zimbabwe an extra 9 months of food at no additional cost. The greatest productivity results when these varieties are used with reduced or zero tillage and keeping crop residues on the soil, as was demonstrated in southern Africa during the 2015-16 El Niño drought. Finally, tolerance in maize to high temperatures in combination with drought tolerance has a benefit at least twice that of either trait alone.

Wheat yields rise in difficult environments. Nearly two decades of data from 740 locations in more than 60 countries shows that CIMMYT breeding is pushing up wheat yields by almost 2% each year — that’s some 38 kilograms per hectare more annually over almost 20 years — under dry or otherwise challenging conditions. This is partly through use of drought-tolerant lines and crosses with wild grasses that boost wheat’s resilience. An international consortium is applying cutting-edge science to develop climate-resilient wheat. Three widely-adopted heat and drought-tolerant wheat lines from this work are helping farmers in Pakistan, a wheat powerhouse facing rising temperatures and drier conditions; the most popular was grown on an estimated 40,000 hectares in 2018.

Climate-smart soil and fertilizer management. Rice-wheat rotations are the predominant farming system on more than 13 million hectares in the Indo-Gangetic Plains of South Asia, providing food and livelihoods for hundreds of millions. If farmers in India alone fine-tuned crop fertilizer dosages using available technologies such as cellphones and photosynthesis sensors, each year they could produce nearly 14 million tons more grain, save 1.4 million tons of fertilizer, and cut CO2-equivalent greenhouse gas emissions by 5.3 million tons. Scientists have been studying and widely promoting such practices, as well as the use of direct seeding without tillage and keeping crop residues on the soil, farming methods that help capture and hold carbon and can save up to a ton of CO2 emissions per hectare, each crop cycle. Informed by CIMMYT researchers, India state officials seeking to reduce seasonal pollution in New Delhi and other cities have implemented policy measures to curb the burning of rice straw in northern India through widespread use of zero tillage.

Measuring climate change impacts and savings

In a landmark study involving CIMMYT wheat physiologists and underlining nutritional impacts of climate change, it was found that increased atmospheric CO2 reduces wheat grain protein content. Given wheat’s role as a key source of protein in the diets of millions of the poor, the results show the need for breeding and other measures to address this effect.

CIMMYT scientists are devising approaches to gauge organic carbon stocks in soils. The stored carbon improves soil resilience and fertility and reduces its emissions of greenhouse gases. Their research also provides the basis for a new global soil information system and to assess the effectiveness of resource-conserving crop management practices.

Managing pests and diseases

Rising temperatures and shifting precipitation are causing the emergence and spread of deadly new crop diseases and insect pests. Research partners worldwide are helping farmers to gain an upper hand by monitoring and sharing information about pathogen and pest movements, by spreading control measures and fostering timely access to fungicides and pesticides, and by developing maize and wheat varieties that feature genetic resistance to these organisms.

Viruses and moth larvae assail maize. Rapid and coordinated action among public and private institutions across sub-Saharan Africa has averted a food security disaster by containing the spread of maize lethal necrosis, a viral disease which appeared in Kenya in 2011 and quickly moved to maize fields regionwide. Measures have included capacity development with seed companies, extension workers, and farmers the development of new disease-resilient maize hybrids.

The insect known as fall armyworm hit Africa in 2016, quickly ranged across nearly all the continent’s maize lands and is now spreading in Asia. Regional and international consortia are combating the pest with guidance on integrated pest management, organized trainings and videos to support smallholder farmers, and breeding maize varieties that can at least partly resist fall armyworm.

New fungal diseases threaten world wheat harvests. The Ug99 race of wheat stem rust emerged in eastern Africa in the late 1990s and spawned 13 new strains that eventually appeared in 13 countries of Africa and beyond. Adding to wheat’s adversity, a devastating malady from the Americas known as “wheat blast” suddenly appeared in Bangladesh in 2016, causing wheat crop losses as high as 30% on a large area and threatening to move quickly throughout South Asia’s vast wheat lands.

In both cases, quick international responses such as the Borlaug Global Rust Initiative, have been able to monitor and characterize the diseases and, especially, to develop and deploy resistant wheat varieties.

Launching digital agro-climate advisory platform in Ethiopia

In this era of climate emergency, what is left when traditional knowledge is no longer enough?

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.

Climate, nutrition and security challenges require global food system transformation

“Can we sustainably feed the nine to ten billion people in our planet in 30 years?” asked Kenneth M. Quinn, president of the World Food Prize Foundation. “This question becomes even more challenging with two current game changers: conflict and climate change.”

Food and agriculture experts met in Des Moines, Iowa, to discuss these issues at the Borlaug Dialogue and awarding of the 2019 World Food Prize.

The focus has shifted over the last few years from food to food systems, now including health and nutrition. “We need an integrated agri-food systems approach for food security, nutrition, nature conservation and human security,” said Bram Govaerts, director of the Integrated Development program at the International Maize and Wheat Improvement Center (CIMMYT).

Speakers agreed that to meet the current challenges of nutrition and climate change, we need a transformation of the global food system. “We have something very positive — this narrative of food system transformation,” said Ruben Echeverría, Director General of the International Center for Tropical Agriculture (CIAT).

In the discussions, speakers highlighted several areas that must be taken into consideration in this transformation.

Food security for peace and development

The theme of this year’s Borlaug Dialogue was “Pax Agricultura: Peace through agriculture.” Panels addressed the interconnected issues of food security, conflict and development.

In the keynote address, USAID Administrator Mark Green issued a call to action and challenged participants “to take on the food and economic insecurity issues that are emerging from this era’s unprecedented levels of displacement and forced migration.” Ambassadors, ministers and development experts gave examples of the interdependence of agriculture and peace, how droughts and floods could create conflict in a country, and how peace can be rebuilt through agriculture.

“Agriculture could root out the insurgency better than anything we did,” said Quinn about the Khmer Rouge surrender in Cambodia, where he served as an ambassador.

In the 1994 genocide in Rwanda, more than 1 million people died in 100 days. Geraldine Mukeshimana, Rwanda’s minister of Agriculture and Animal Resources, explained that in the country’s rebuilding process, all policies centered on agriculture.

“Almost no country has come out of poverty without an agricultural transformation,” said Rodger Voorhies, president of Global Growth and Opportunity at the Bill & Melinda Gates Foundation, in a fireside chat with 2009 World Food Prize Laureate Gebisa Ejera.

Agriculture is vital because without food, we cannot build institutions, processes or economies. “You cannot talk about human rights if you don’t have any food in your stomach,” said Chanthol Sun, Cambodia’s minister of Public Works and Transportation.

Josette Sheeran, president and CEO of Asia Society, echoed this thought, “Nothing is more important to human stability than access to food.”

In a luncheon keynote, Víctor M. Villalobos, Mexico’s Secretary of Agriculture and Rural Development, spoke about CIMMYT, the MasAgro project, and the need to improve food systems and agriculture to fight violence and forced migration. “Agriculture, prosperity and peace are inextricably linked together.”

How to make technological innovations work

Innovations and technology can support a global food system transformation and help to achieve the Sustainable Development Goals.

In a panel on food security in the next decade, speakers shared the agricultural technologies they are excited about: data, gene editing, synthetic biology, data science and precision farming.

Josephine Okot, managing director of Victoria Seeds Ltd said, “We must have mechanization.” She described the fact that Ugandan women farmers still rely on hand tools as a “disgrace to humanity.”

The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) organized a session where panelists discussed how to realize a transformation in food systems through next generation technologies, highlighting the role regulatory frameworks and policies play in the adoption of new technologies.

Making innovations work is about more than developing the product. “It takes a lot more than just a good seed to get a farmer to use it,” said 2019 World Food Prize Laureate Simon Groot. “It includes good distribution, good marketing, good training, etcetera.”

Technology adoption requires a human emphasis and cultural element in addition to technology development.

Breeding demand-driven crops for all

“The real enemy of farmers is lousy seeds,” said Simon Groot in his speech after receiving the World Food Prize.

CGIAR took the occasion of the World Food Prize to launch a new initiative, Crops to End Hunger. “We are looking for big solutions at CGIAR. Crops to End Hunger is one of them,” said CIMMYT Director General Martin Kropff. This program aims to meet the food, nutrition and income needs of producers and consumers, respond to market demands and increase resilience to challenges of the climate crisis.

“CGIAR released 417 new varieties last year. However, we can do more. Crops to End Hunger will rapidly excel breeding cycles,” said Elwyn Grainger-Jones, CGIAR Executive Director.

Felister Makini, deputy director general for Crops at Kenya Agricultural & Livestock Research Organization (KALRO), explained that focusing on the end users is what will have real impact. “It is important to develop technologies that are demand-driven so that farmers want to grow them and consumers want to buy and eat them.”

In a session to unpack the Crops to End Hunger initiative hosted by Corteva Agriscience and CGIAR, Marco Ferroni, Chair of the CGIAR System Management Board, said that CGIAR is shifting toward a more demand-driven agenda for plant breeding, where markets dictate what the research priorities should be.

“We must consider the human aspect in breeding,” said Michael Quinn, Director of the CGIAR Excellence in Breeding Platform (EiB). “This is where success will really come.”

Panelists discussed gender-conscious breeding, or taking both women and men’s desired traits into account.

The theme of gender was also emphasized by 2019 Norman Borlaug Field Award winner Hale Ann Tufan. She asked the Dialogue attendees to question gender biases and “not only to ‘take it to the farmer’ but take it to all farmers.”

To mitigate the food security and economic risks of South Asia’s frequent and intense droughts, scientists and policymakers from the South Asian Association for Regional Cooperation (SAARC), the International Centre for Integrated Mountain Development (ICIMOD) and the International Maize and Wheat Improvement Center (CIMMYT) recently joined forces to launch an innovative decision support and agricultural planning system that combines remote sensing and  climate data analysis for drought monitoring and early warning.

The Regional Drought Monitoring and Outlook System application was unveiled during a workshop to train experts and policymakers in its use at relevant regional and national institutes in Islamabad, Pakistan, from July 29 to August 1, 2019. The Regional Drought Monitoring and Outlook System is the product of an ICIMOD-CIMMYT partnership through the United States Agency for International Development (USAID) and the National Aeronautics and Space Administration (NASA) supported SERVIR Hindu Kush Himalaya (HKH) programme, in collaboration with Climate Service for Resilient Development (CSRD), led by ICIMOD and CIMMYT, respectively.

“Commonly associated with epic flooding, particularly in the enormous breadbasket region known as the Indo-Gangetic Plains that extends across Pakistan, India, southern Nepal, and Bangladesh, the region also faces droughts driven by rising temperatures and erratic rainfall and which threaten crops, food security, and livelihoods,” said Faisal Mueen Qamer, Remote Sensing Specialist of ICIMOD, which helped develop the system and organize the workshop.

“We expect the system to foster resilience in South Asian agriculture, while supporting future institutional frameworks and policies for farm compensation and adaptation, through decision makers’ access to timely and action-oriented information,” Qamar explained.

With a growing population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land. A 2010 study found a linear drop of 7.5% in rainfall in South Asia from 1900 to 2005.

“Shrinking glaciers, water scarcity, rising sea levels, shifting monsoon patterns, and heat waves place considerable stress on South Asian countries, whose primary employment sector remains agriculture,” said Mohammad Faisal, Director General for South Asia at Pakistan’s Ministry of Foreign Affairs, during the workshop opening.

Media reports in early 2019 documented displacement and hunger from Pakistan’s worst drought in years.

Raising awareness about drought and its mitigation

Twenty-three participants from six South Asia countries plus five expert instructors attended the workshop, which offered presentations and hands-on training on a suite of applications and associated data analysis tools, including the South Asian Land Data Assimilation System (SALDAS), the Regional Drought Explorer, and the National Drought Early Warning System.

Muhammad Azeem Khan, Member of the Food Security & Climate Change at the Planning Commission of Pakistan, said the scale of present and future climate challenges is clearly evident.

“In Pakistan, we regularly see parts of the country in the grip of severe drought, while others have flash floods,” Khan commented during the workshop closing, while commending its organizers. “Frequent drought diminishes agricultural production and food security, especially for people in rural areas. Effectively managing the impacts of climate change requires a response that builds and sustains South Asia’s social, economic, and environmental resilience, as well as our emergency response capacity.”

Through CSRD, a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries, CIMMYT helped extend the Regional Drought Monitoring and Outlook System to Bangladesh, from its original coverage of Afghanistan, Nepal, and Pakistan.

“Translating complex climate information into easy-to-understand and actionable formats is core to CSRD’s mission and helps spread awareness about climate challenges,” said Tim Krupnik, CIMMYT cropping systems agronomist based in Bangladesh. “This consortium provides strength and technical expertise to develop relevant climate products, including decision-support information for farmers and other stakeholders, thus fostering resilience to climate-related risks.”
