Sagar has been working at CIMMYT-Nepal since December 2015, contributing to various projects. His main focus has been on the CSISA initiative, which aims to research and scale up resource-saving technologies within Nepal’s cereal systems. Through his work, he has developed expertise in technology scaling within cereal systems, developing market systems, and strengthening governance in the agricultural research and extension services sector. This is in part due to his strong understanding of local contextual factors that influence the adoption of sustainable intensification technologies, including mechanization.

Since 2024, Sagar has turned his attention to generating innovations, tools and scaling pathways in the mixed farming systems of the mid-hills of Nepal as part of the CGIAR Mixed Farming Systems (MFS) Initiative.

Him Lal Neupane has been in the business of agriculture for more than a decade. His company Annupurna Suppliers, in Banke District, Nepal, trades in agri products and has an annual turnover of around $626,000, up from $195,000 eight years ago.

Recently, Neupane has been heavily investing in maize. He says involvement from the International Maize and Wheat Improvement Center (CIMMYT) in market strengthening has given him the confidence to go big on the crop. He encountered CIMMYT through the meetings led by the organization in the district, as part of its Nepal Seed and Fertilizer (NSAF) project. In the meetings, he was able to hear perspectives on maize production from leading market experts, as well as government officials. Getting direct access to high level government representatives and agricultural scientists was incredibly fruitful and raised his confidence to invest in maize. He also got to air his own grievances about the industry and learn more from other farmers.

“I learnt that the project was invested in training farmers to produce better quality maize,” said Neupane. “If we get quality products from farmers, I immediately deduced that there is a great chance that the product will keep doing well in the market.”

In 2022, Neupane bought a truck and has been constructing a massive storage facility that can store up to 4 million kilograms of produce. He has plans for proper grading and drying of maize in the facility to sell to industrial buyers.

The majority maize in Nepal is used as feed for the poultry industry, so there is high value for the crop in the market. “Since Nepal is a big consumer of poultry products and will remain so, it is inevitable that locally produced maize will sell,” explained Neupane.

Neupane went into agriculture because he could not secure employment after completing higher education. He grew up learning and practicing farming, so he understood farmers’ plights and wanted to start a company that would improve their lives. He also wants to grow the industry to curb the country’s maize import dependence, which has been affected by recent disruptions like the Ukraine conflict and the pandemic. Annually, Nepal imports around $120 million worth of maize, which depletes the country’s foreign currency reserves.

CIMMYT’s efforts in developing the maize market through value chain coordination and private public partnerships intend to help stakeholders at every level of the industry, from farmers to suppliers like Neupane, whose company’s growth represents a strong reinforcement of confidence in domestic maize production.

Nepal Government endorses new site-specific fertilizer recommendations for rice

After four decades, new site-specific fertilizer recommendations for rice have been introduced in Nepal that will help farmers increase the crop’s productivity by 10-30%, compared to their current practices.

The Ministry of Agriculture and Livestock Development (MoALD) endorsed the new fertilizer recommendations for rice crop at a consultative workshop in July 2022 held in Kathmandu. Developed by the International Maize and Wheat Improvement Center (CIMMYT), in close collaboration with the Nepal Agriculture Research Council’s (NARC) National Soil Science Research Center (NSSRC) and International Fertilizer Development Center (IFDC), the new regime replaces the existing blanket approach of recommendations to help increase crop yields and fertilizer use efficiency.

The blanket approach assumed the whole country as one domain despite the heterogeneity in soils, other biophysical conditions and agronomic management practices, including crop varieties. As a result, fertilizers were under-utilized in low fertile soils or overused in farms with high soil fertility status, thereby farmers were not able to obtain the achievable yield.

Unlike the generic recommendations, the site-specific fertilizer management will help farmers to determine the crop’s fertilizer requirements based on soil fertility status of a particular farm, attainable yield target of the selected crop variety, crop’s yield response to fertilizers and agronomic management practices, such as irrigation, cropping systems etc. In other words, this new regime allows farmers to produce more with less fertilizers through a balanced application of fertilizers based on available soil properties.

Old is not always gold

Generally, soil fertility status changes every 3-5 years when there is continuous nutrient removal from soils due to an intensive cropping system with the adoption of high nutrient demanding improved and hybrid varieties. Thus, soil fertility management recommendations should be updated periodically but the existing recommendations were not updated since 1976.

Realizing the limitations, CIMMYT through the Nepal Seed and Fertilizer (NSAF) project, supported by USAID, worked with NSSRC and IFDC to formulate fertilizer recommendations for major cereal crops and vegetables for specific domains of the country.

Under NSSRC’s leadership, a ‘Fertilizer Recommendation Committee’ comprising of a dedicated team of soil scientists within NSSRC and NSAF experts was formed to develop site-specific fertilizer recommendations using the Soil-SMART framework for delivering balanced fertilizers to farmers. Based on soil fertility status, agro-climate, irrigation regimes and geography, the country was divided into six soil fertility domains — four in the Terai region (Eastern, Central, Western and Far-western), one in inner Terai and one in the hills. Under each domain, recommendations were based on the attainable yield, crop variety, and irrigation regime.

This approach was first tested for rice crop.

Formulating new recommendations for rice

Three fundamental steps were used to develop site-specific fertilizer recommendations, which included: i) selection of yield goal, ii) estimation of crop nutrient requirement, and iii) estimation of indigenous nutrient supplies. To collect this information, NSAF and the committee designed field trials on nutrient omission and nutrient rates to determine the yield limiting nutrients and their optimum rate, respectively. Data from fertilizer trials conducted by different research institutes and universities, including trials from the project sites were collected and analyzed by the team to see the crop’s yield response to fertilizers. A modeling approach called Quantitative Evaluation of fertility of the tropical soils (QUEFTS) was also used to estimate the indigenous nutrient supply and attainable yield target of rice for different soil fertility domains. This model was applied as an alternate to extrapolate recommendations in areas where field data were not available, considering large financial and human resources required otherwise to conduct numerous field trials across different soil types and agro ecological zones. The model was validated with field trial data before making extrapolation of the recommendations. The QUEFTS model used soil properties from Nepal’s first digital soil map to identify nutrient status and deficiency.

In addition to agronomic optimum rate, an economic analysis was also conducted to see economic variability of the recommendations.

The newly developed recommendations provide guidance for balanced fertilization as it includes micronutrients zinc and boron, and organic inputs in addition to three major nutrients —Nitrogen, Potassium and Phosphorous (NPK). Results from field trials suggested that the new recommendation could increase rice productivity by 10-30% compared to existing farmers’ practice.

Advocating for endorsement

A three-day workshop was organized by CIMMYT and NSSRC to primarily share and approve the recommended fertilizer dose for rice crop as well as its relevance to achieve potential yield at farm level. Rajendra Mishra, joint secretary of MoALD inaugurated the event that was chaired by the Director of NARC’s Crop and Horticulture Research. Workshop attendees included MoALD, NARC, Department of Agriculture, USAID Nepal, secretaries from the Province Ministry of Land Management, soil scientists, university professors, agronomists and other high-level government officials.

During the workshop, NSAF explained the application of QUEFTS model with reference to the case of rice based on the field trial data for domain specific fertilizer recommendations. Shree Prasad Vista, soil scientist at NSSRC, summarized the results for rice as the approach and facilitated its approval from MoALD. The participants also discussed on strategies to link with the extension system to reach a large number of farmers through the three-tier governments. Fourteen research papers on nutrient management for major cereal crops were also reviewed at the event.

“I congratulate NARC for this historical work on updating the fertilizer recommendations after 46 years. Now, we are moving towards sustainable soil fertility management by adopting site-specific fertilizer recommendations,” said MoALD Secretary Govinda Prasad Sharma.

Although the recommendation for rice was a significant output of the workshop, fertilizer recommendations for other major crops will be carried out following a similar process.

NARC’s Executive Director Deepak Bhandari commented, “It is our pleasure to move from a blanket approach to site-specific approach. This is a milestone for agricultural research in the country and I would like to thank all the scientists, NSAF project and USAID’s support for this notable achievement.”

Similarly, speaking at the event, Jason Seuc, Director of Economic Growth Office at USAID Nepal, emphasized the importance of soil fertility management for achieving food security targets set by the Government of Nepal. Seuc remarked that a sustainable soil fertility management is critical not only for food security but also for reducing the environmental pollution.

Worsening food insecurity calls for stress-tolerant seeds

Written by Sarah Fernandes on . Posted in In the media.

From chemical fertiliser shortages to lack of irrigation, farmers in Nepal have been facing a multitude of human-induced problems every year. The most urgent concern is the climate crisis.

Erratic weather patterns, untimely and uneven rainfall and rapidly rising temperatures have got farmers by the scruff of their necks.

For the farmers, such dramatic climate change manifests in the form of floods, droughts and landslides, directly hitting their agriculture-dependent livelihoods. For the nation as a whole, the climate crisis worsens food insecurity.

The tales of the climate crisis are petrifying. However, not all hope is lost.

Interventions such as climate resilient seeds that are tolerant to extreme climatic stresses like drought, flooding or submersion have been discovered and implemented in phases, according to scientists, to help sustain agricultural productivity.

“Due to the increasing climate change impacts, farmers are facing challenges to produce traditional seeds used during normal situations,” says AbduRahman Beshir Issa, seed systems lead at the International Maize and Wheat Improvement Centre, South Asia Office.

“In Nepal, farmers are witnessing both drought stress and excess moisture during the summer cropping season. In the spring season, high temperatures, coupled with drought stress, make it difficult for normal seeds or varieties to grow.”

With an increasing number of mouths to feed, and more pronounced effects of climate change yet to present themselves, climate-resilient seeds can help sustain Nepal’s agricultural productivity, according to crop development experts.

“Climate resilient seeds are crucial for food security. In addition, these crops are nutritionally important,” said Prakash Acharya, a senior crop development officer at the Seed Quality Control Centre. “With changing climate, not all crops and seeds can endure even two-three days of drought or submergence or extreme heat.”

Approximately 3 million hectares of land is cultivated in Nepal, which is 21 percent of the total land area. Rice, maize and wheat constitute more than 80 percent of cereal acreage and production.

The overall cereal yield in Nepal is 2.6 tonnes per hectare, which is far lower than the regional and global average of 4.1 tonnes per hectare, indicating an overall low productivity.

Paddy constitutes the highest production, commanding a 20.8 percent share in the agriculture gross domestic product (AGDP).

Nepal’s economic wellbeing is intimately linked with the monsoon. Water from the skies is the lifeblood of Nepal’s Rs4.85 trillion economy which is farm-dependent, as nearly two-thirds of the farmlands are rain-fed.

A large part of the country gets nearly 80 percent of its annual rainfall during the four months—June to September.

The production of food grains, mainly rice, depends on the amount and distribution of monsoon rainfall over the country. The monsoon rains also replenish ground water and reservoirs critical for drinking and power generation.

Analysing data from the past 33 years of minimum and maximum temperatures and rainfall, scientists predict drought to be the most important limiting factor for crop production, including paddy.

As paddy is sensitive to drought due to its high water requirement, scientists say there is a need for promoting “climate change-ready rice” that can tolerate drought for up to months.

For instance, research in Nawalparasi in the central Tarai found that the existing paddy varieties would not sustain the yield potential of the present level after 2020.

In October 2021, unusual weather patterns led to a torrential downpour lasting three days, causing massive loss of agricultural harvests and physical infrastructure across many parts of Nepal.

In 2020, in East Rukum, continuous rainfall from January to September decreased maize yield. The drought that followed then destroyed the wheat crop. Right after, the heavy rains also wiped out potatoes and maize.

Climate projections further suggest changes in precipitation during the monsoon period (with variations from 14 percent to 40 percent), as well as the increased likelihood of heavy precipitation events.

Experts are concerned that such unpredictable changes in weather patterns will lead to a decline in agricultural productivity, further worsening food insecurity in the region.

“We aren’t food secure right now as well. And with climate change, it is only getting worse. In the long run, the condition of food security in Nepal will be alarming,” says Yamuna Ghale, agriculture and food security policy analyst who is also research director at the Nepal Centre for Contemporary Research.

Around 65 percent of Nepal’s population depends on agriculture for its livelihood, which accounts for 25 percent of the GDP.

With the increasing population and declining agricultural productivity, experts say that Nepal could sooner or later face food insecurity.

“Everyone has the right to food. But the current situation indicates that a food shortage is looming,” said Ghale, who is also an expert at the Food Security Coordination Committee under the Ministry of Agriculture and Livestock Development. “We have to focus on climate-smart alternatives now, beginning with climate-resilient seeds.”

Climate-resilient seeds can withstand extreme conditions brought about by climate change. For example, drought-tolerant seeds can sustain periods of dry conditions, and submergence-tolerant seeds can withstand flood stress.

For example, improved varieties like Sukkhaa Dhan 4, Sukkhaa Dhan 5 and Sukkhaa Dhan 6 have an average yield of 4-4.5 tonnes per hectare, and under good irrigation conditions, the output can go up to 5.5 tonnes per hectare on an average.

Sukkhaa 6 has the ability to re-grow even two weeks after submergence.

Swarna Sub-1, Sambha Mansuli Sub-1, Cherang Sub-1, Gangasagar-1, and Gangasagar-2 are submergence-tolerant paddy varieties.

Rice varieties like Bahuguni-1 and Bahuguni-2 are both drought and submergence tolerant.

Similarly, maize varieties that are drought tolerant, such as Deuti, Manakamana-5 and Manakamana-6 are also available. Rampur hybrid-10 and Rampur hybrid-12 are heat-tolerant varieties.

Seto Kaguno is a promising variety of foxtail millet that is drought-tolerant and extremely climate-resilient.

Paddy varieties which possess the “Sub1A” gene remain dormant during submergence, and conserve energy until the floodwaters recede. Paddy plants with the “Sub1A” gene can survive more than two weeks of complete submergence. The plant recovers well from drought by growing new shoots.

“A character is incorporated into existing rice varieties to make them stress-tolerant or climate-resilient. This makes them fare better than traditional crops,” said Acharya.

“In very recent years, because of climate change, we have begun researching drought- and submergence-tolerant seeds,” said Acharya.

These climate-smart varieties, which can survive under stress and retain desirable grain qualities, can create positive impacts on the lives of farmers, scientists say.

Since 1966, Nepal has released and registered 144 varieties of paddy seeds, according to the Agriculture Ministry.

Scientists say that a majority of these stress-tolerant varieties do not demand excess fertilisers or tillage methods.

The Nepal Agriculture Research Council (NARC) is spearheading various projects for producing and popularising drought- and submergence-tolerant seeds.

“Under USAID’s support, Nepal Seed and Fertiliser Project, paddy seeds which are drought and submergence tolerant are being produced and marketed in Nepal in partnership with the government and the private seed companies,” Issa said in an email.

The National Maize Research Programme of NARC has released heat stress-tolerant maize hybrids that can survive at high temperatures compared to traditional varieties.

Likewise, under the National Grain Legumes Research Programme of NARC, field testing of waterlogging-tolerant lentil varieties is being done to come up with varieties that can withstand excess moisture from unusual winter rains during the lentil growing season, according to Issa.

Despite the availability of stress-tolerant seeds, farmers are not much aware of the new varieties and are hesitant to adopt such seeds easily.

Due to lack of awareness, farmers hardly adopt new varieties and they prefer traditional varieties. Local governments too have failed to create awareness.

According to experts, Sukhaa Dhan 3, Samba Mansuli Sub-1 and Cherang Sub-1 are popular among farmers in the Tarai and mid-hills.

However, varieties like Bahuguni-2 have been rejected by farmers because “Nepali consumers prefer non-sticky, fluffy rice as opposed to sticky varieties,” experts say.

Despite being both drought and submergence tolerant, such varieties are not adopted by farmers.

“Farmers are enthusiastic about using new ways and techniques of farming, but local governments have completely ignored investing in agriculture,” said Ujjal Acharya, freelance researcher on climate change and environment economics.

“They have been more focused on building infrastructure, roads, bridges, temples and so on. Food security, climate resilient agriculture, organic farming—all do not fall within the priorities of local governments,” he said.

However, scientists acknowledge that climate resilient crop varieties are only a part of the solution of the bigger climate-resilient agricultural system.

“It is extremely important to develop climate-resilient crop varieties that can withstand extreme weather conditions, but seeds are just one part among the various solutions,” says Issa.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) are conducting a study in the state of Bihar, India, to improve our understanding of women’s and men’s contributions to decision-making around wheat crop management. The results will help reach women with new varieties that meet their needs and priorities.

The study seeks to overcome a big challenge for research organizations and national policymakers: to design a better framework for faster turnover of improved varieties and increased access to women and marginalized farmers.

Wheat is the second-largest crop grown in Bihar after rice, with a production of 5-6 million tonnes of it every year. Despite women’s contributions to farming activities, from sowing to harvesting, traditional gender norms can undermine their access to productive resources and influence household decisions. Additionally, women’s workload in wheat agriculture is increasing, due to men’s departure to non-agricultural jobs, but women are still not necessarily recognized as capable farmers.

Gender exclusion in agriculture

Given social norms and household-and-farm labor division based on gender, women are often confined to specific roles in the agricultural production system. In smallholder farming communities of South Asia like Bangladesh, India, and Nepal, men’s increasing involvement in non-agricultural activities has increased women’s workloads in every sphere of agricultural production. However, these long-held assumptions of their role can lead to exclusion from decision-making, limiting their control over what, how, and how much a crop is produced, their economic wellbeing, including household food security.

The CIMMYT study on “Intra-household gender dynamics in decision-making for wheat crop management in India (Bihar)” investigates women’s and men’s roles in production decisions. Led by Hom Gartaula, Gender, and Social Inclusion Specialist at CIMMYT, it covers eight villages — four in Darbhanga and four in Madhepura district — with 25 houses considered in each village.

As part of the Accelerating Genetic Gains in Maize and Wheat for improved livelihoods in Asia and Africa (AGG)  project, the research study will help gain deeper insights into the intra-household gender dynamics. It will also help in untangling who does what, how wheat cultivation and management decisions are organized within the households and the perceptions of the male and female farmers around why decisions are made in such a way.

Storytelling through household decision-making scenarios

In traditional rural societies, survey-based data collection might not be the best way to evaluate women’s agency, as the deeply rooted cultural restrictions might not allow them to talk openly about sensitive issues, like their relationship with a spouse. This study uses an innovative storytelling approach to data collection: using vignettes, farmers are given short stories to relate to their household circumstances. Stories are also easier to remember and help build a connection with the characters quickly.

The vignettes approach was first applied in the context of smallholder maize production in Kenya under the AGG project. According to Rachel Voss, the leader of the Kenyan study, “Using vignettes to explore decision-making in both East Africa and South Asia allows us to learn and compare across these regions and across crops. Gender relations in Indian wheat and Kenyan maize production might look similar in some ways, but very different in other ways, and our research and programming will need to respond to those differences.”

In this study, five vignettes with fictitious husband and wife characters are presented to participants to represent the different ways production and consumption decisions are made in the household. These vignettes describe how they engage in key decisions like seed procurement, labor hired, and harvest used for consumption or sale. With guidance from evaluators, respondents identify which scenario best aligns with the decision-making process in their household.

Researchers feel this qualitative data, gathered through a storytelling approach, could guide the reach of gender interventions in a more effective way. Gartaula and the team explained that the participants can build connections to a character in the story without biases, expressing their experiences in household decision-making through vignettes. They also observed that sometimes what the participant shared is the opposite of their assumption of women being excluded from decisions.

Rethinking gender roles

Traditional gender roles are deeply entrenched in the region. In the farming communities of rural Bihar, one might assume that who does what in wheat-rice cultivation is obvious, and it has been well studied in the past. However, investigating the stereotypes around gender to understand practices within households is an innovative aspect of this study.

For example, landless couple Pappu Paswan and Kamini Devi of village Kamtaul in Darbhanga district have been cultivating wheat on leased farm plots for many years. Devi is engaged in every aspect of decision-making. “We cultivate in leased plots of different sizes, spread across, requiring more effort and time in attending to them. We discuss additional labor during harvest and if there is money enough to pay them,” said Devi pointing her finger at the vignette illustrating ‘cooperation’ in household decision-making. They produce enough for their consumption, but when possible, “I advise my husband to sell some for income,” she added.

Despite contributing to decisions jointly with Pappu when it comes to farm labor and household finances, Devi has little or no knowledge of seed varieties and access. Her husband informs that it was UP262 (wheat seed variety) they have been cultivating for the last two years.

In Rishikesh Ram’s household, land ownership and livelihood specialization were factors in decision-making. He owns the land and makes all farming decisions, including how much will be saved for consumption at home. His wife, Kiran Devi, a nurse at the village primary health center, is hardly involved in any farming work. “As the income from her job contributes to expenses at home, decisions about loans or payment for labors on the farm are joint decisions,” Ram said.

“In these two households of the diverse decision-making process, different approaches to messaging and relevant extension services must be explored to address the issues of exclusion, access, and knowledge gaps in these households,” Gartaula observed.

Bridging the gender gap in agri-food systems

With the feminization of agriculture in the region, women’s contribution to agricultural production is likely to increase. Policy and research interventions must recognize this growing population and support their full economic and social contributions as cultivators, entrepreneurs, and laborers. However, whether women’s growing role in wheat production leads to increased decision-making authority and empowerment is still unknown. But hope is that AGG-supported gender research in South Asia and East Africa will help guide actions on gender and social inclusion in agri-food systems and support cross-learning between the regions.

Cereal seed value chains in Nepal

Written by Sarah Fernandes on . Posted in Publications.

Cereals cover around 80% of Nepal’s cultivated land area, with a low level of productivity. The country’s commercial cereal seed sector development has been rather slow as more than 83% of seed comes from the informal system. The formal sector cannot produce adequate seeds to meet the farmers’ needs. Moreover, the formal market is largely driven by public seed varieties. To catalyze the sector’s development and enhance productivity, building a well-performing seed system that produces and timely supplies quality seeds at affordable rates to farmers is integral.

The adoption of a federal system of governance since 2018, creating new structures within the system, along with the after-effects of COVID-19 has impacted the public sector seed production and distribution with implications on private seed business. A recent assessment conducted by the International Maize and Wheat Improvement Center (CIMMYT) examines the current functions in the cereal value chain in Nepal and identifies upgrading strategies to bring efficiency and competitiveness in the cereal seed market systems, specifically for rice and maize.

The study provides a detailed analysis of the market size and trends for the various hybrid and open-pollinated varieties of rice and maize seeds as well as their production, distribution and margins in seed business.

A majority of rice and maize seeds, especially high-yielding hybrids, sold to farmers are brought in by importers and wholesalers who directly sells them to farmers or indirectly through agro-dealers. Nepali hybrid varieties are lagging because farmers, grain producers and millers have low awareness and information on new and improved varieties produced by local seed companies and cooperatives. A significant supply gap of rice and maize seeds was found in all the seven provinces of Nepal.

The study reviews the nature of inter-business relations in the seed value chain and provision of services by the government, NGOs and others for the development of the cereal seed value chain. In the context of federalism, the study assesses the seed policies and actions under the Revised Seed Act (2020) to establish provincial seed systems. Considering migration-induced feminization of agriculture in Nepal, the study identifies approaches to promote inclusive seed systems and youth engagement in seed value chains. Strategic measures to build a resilient seed system that can respond to abrupt market and mobility disruptions, as caused by the COVID-19 pandemic, is also taken into account. However, it also details out the various challenges and risks encountered by the value chain actors that hinders seed business and the sector’s growth overall.

Some of the strategies to address these bottlenecks include strengthening value chain functions in research and development, hybrid seed production, seed processing and innovative approaches for market promotion and sales. Creating an enabling environment for seed companies in areas of variety testing and release, quality assurance in seed production and commercialization, financial and business management services, seed extension services and promotion of new domestic varieties are also fundamental propositions to achieve Nepal’s National Seed Vision (2013-2025) targets.

Managing seeds and agricultural losses in the wake of extreme climate events: Lessons from Nepal

As climate change-induced disasters surge around the world, it is the people of the least developed countries paying the bulk of the costs.  According to the International Disaster Database, the number of disasters across the globe has risen by 74.5% — comparing data from 1980–1999 with 2000–2019 — and these numbers are expected to increase due to the most recent climate change scenarios. The major climate change impacts identified by the Intergovernmental Panel on Climate Change relevant for Nepal include an increase in economic losses from weather and climate-related events, with a significant contribution related to agricultural losses.

In Nepal, for example, an unexpected and untimely excessive rainfall and flood in October of 2021 caused massive damage to the ready-to-harvest crop across all major rice-producing areas of Nepal – threatening the food security and livelihood of the country’s smallholder rice farmers.

A rice damage assessment was essential to gather insights on the seed production losses and propose anticipatory measures for seed management and distribution to farmers for the next season. Thanks to a collaboration between scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Integrated Mountain Development (ICIMOD), a rapid loss assessment through a survey of rice-growing farmers was conducted to quickly assess the damage and recommend critical operational decisions to the Nepali government to mitigate the impact. With the help of an operational mobile app, Geofairy, the USAID-supported Nepal Seed and Fertilizer project (NSAF), implemented by CIMMYT, surveyed 253 farmers in six districts of the mid and far western region with a particular focus on the potential seed production losses for next year’s cultivation.

Unforeseen disaster

The 2021 disaster in Nepal came as a shock to farmers: the 2021 monsoon was proceeding as forecasted in the seasonal outlook, and by the end of the season, farmers were generally expecting bumper rice crops. The withdrawal of southwest monsoon system was declared in early October. However, from 18-20 October 2021, instead of dry spell, the country experienced a three-day excessive rainfall and accompanying flooding that caused massive damage to the ready-to-harvest crop across all major rice-producing areas in the southern lowland Terai region of Nepal.

The partially harvested and standing crop suffered three kinds of damage. First, farmers near the riverbanks lost their ready-to-harvest paddy as it was swept away by flash floods. The second category was in the low-lying southern plains, where rainwater inundated the harvested, but not collected, paddy fields for more than two days, causing seeds or grains on the panicles to sprout. Sprouted seeds on the mother plant have reduced germination capacity and vigor, and cannot be stored for a long period while maintaining the germination capacity. The third damage was stem and root lodging (falling over) due to powerful winds.

Digital technologies for rapid damage assessment

With conventional approaches, on-ground damage assessments after a disaster can take weeks, sometimes months, limiting critical operational decisions in the first few hours and days. However, Nepal’s Ministry of Agriculture and Livestock Development (MoALD) was already prepared: since 2019, the Ministry has been using satellite remote sensing for in-season rice area estimation through the USAID-supported SERVIR HKH program.

Thanks to the platform, experts from ICIMOD were able to share a satellite image-based assessment as early as 22 October 2021: two days after the flood.

This existing digital crop monitoring platform was used to produce a rapid-damage assessment to provide an analytical basis for initial decisions. In the rapid damage assessment, GMP IMERGE satellite data was used to measure the rainfall intensity across Nepal (Figure 1) and Selntinel-1 SAR satellite data was used to map flood water extent in the Terai district of Nepal on 21 October 2022. The assessment also served as a planning tool for in-depth damage evaluation for farmer compensations.

Widespread flooding

Satellite precipitation data showed the occurrence of hefty rainfall in Morang, Sunsari, Saptari, Siraha and Jhapa districts in the Eastern region. In the Western region, Kailali and Kanchanpur experienced intense rainfall, while most of the central districts of the Terai region remained below heavy rain.

Based on satellite images acquired, the flood extent assessment showed major flood spread in the western parts, including Kanchanpur, Kailali, Bardiya and Banke districts (Figure 2). The flood water extent remained lower in the Eastern districts compared to the West. The causes of severe damage were from direct rain pour and winds in the Eastern region, and flood swept from riverbanks in the Western parts.

Assessment results: Reduced seed quality and shortage of rice seed supply for the next planting season

According to a field-based assessment, the two most popular varieties, Radha-4 and Sarju-52, are the most affected by the flood, especially in Banke, Bardiya, Kailali and Kanchanpur districts. Accordingly, 89% of Radha-4 and 42% of Sarju-52 seed production field has faced partial or complete loss in the surveyed districts. As per the district-wise loss assessment, 80% of Sirju-52 grown in Kailali and 61% in Kanchanpur suffered 50-100% damage. Similarly, nearly 60% of Radha-4 grown in Banke and Bardiya districts has suffered a crop loss ranging from 50-100%. This clearly indicates a huge shortage of these varieties for the next rice season which calls for immediate action to mitigate the seed deficit.

The survey found that farmers in Bardiya, Banke and Kailali had severe or complete crop loss, while those in Kanchanpur, Kapilvastu and Rupendehi had partial crop failure (Figure. 3)

Losses and the limits of early warning systems

According to the government’s final estimates, about 1,10,000 ha of rice crop area was damaged across the country. Respondents from the western districts reported that 80% of the farmers could only manage 50% or less than the expected harvest. The farmers reported an average input cost of $526 per hectare (NPR 63,162 per ha) and gross expected income of $972 per hectare (NPR 116,674 per ha) – leaving a very narrow margin of profit. To compensate for this economic blow, the government distributed  $43 million (NPR 5.52 billion) among the farmers. However, with a total loss of $0.1 billion (NPR 12 billion), farmers still suffered a great loss.

Although early warning systems were in place in the surveyed districts, some respondents expressed low trust and reliability in the early warnings and only 20% of respondents were aware of the heavy rainfall forecast issued three days before the extreme event. Earlier studies in the Ganges basin have suggested that a 10–20-day lead-time forecast is needed to avoid agriculture losses. However, predicting a high magnitude of low-frequency extreme events with sufficient advance notice is still a significant challenge in climate science.

How to mitigate and weather such challenges?

Nepal’s rice seed replacement rate is around 20%, which means that about 80% of farmers are not accessing good quality seeds every season. The addition of this untimely flash flood and the subsequent seed loss will further worsen seed availability, in turn contributing to food insecurity at the national level. The assessment findings have several implications for actions needed to mitigate future climate shocks.

  • Among other mitigation approaches, stakeholders need to assess in-country level quality rice seed availability and design a plan to mobilize preferred varieties from the surplus districts — less affected by the flood — to those in need.
  • During challenging times, maintaining seed quality standards might be difficult. Hence, stakeholders need to consider adopting a flexible quality standard such as “quality declared seeds” in similar emergency scenarios. The “quality declared seed” standard helps as an important intervention when normal seed production is greatly affected by drought and/or flood. It offers alternative seed quality standards for seed producers to provide seeds and ensure continuity of crop production.
  • Promoting climate-resilient varieties, especially lodging- or submergence-tolerant rice varieties, will better withstand flooding as compared to the susceptible ones.
  • Furthermore, farmers need access to a suitable crop insurance scheme to offset seed losses during extreme weather events. For instance, seed growers can purchase a group insurance scheme where customized premiums could be available to the members.

Some of the above mitigation approaches can be applied when extreme weather events are well forecasted and less severe. However, in the wake of an emerging climate crisis and limited mitigation options, there is a need to balance efforts on all aspects of adaptation, including the adoption of crop management practices including accelerated varietal turnover to modify threats and prevent adverse impacts, strengthen early warning systems with a focus on last-mile connection to minimize damages, and develop innovative mechanisms to address risk transfer and loss and damage compensations for sharing losses.

Pablo D Olivera Firpo

Scientist Pablo D Olivera Firpo has been awarded the Excellence in International Service Award by Advancing the Science of Plant Pathology (APS) for outstanding contributions to plant pathology by APS members for countries other than their own.

Firpo was born in Montevideo, Uruguay, where he received a BSc degree as an agronomy engineer in 1997 from the University of the Republic, College of Agronomy. His PhD degree in 2008 was from the Department of Plant Pathology at the University of Minnesota (UMN). He began his career as a postdoctoral research associate with the Department of Plant Pathology and the USDA-ARS Cereal Disease Lab, and then became a research assistant professor in the Department of Plant Pathology at UMN in 2017.

Firpo has been a vital member in the global cereal rust pathology community and contributed substantially to the fight against Ug99 and other virulent wheat stem rust races that have re-emerged around the world and pose serious threats to food security. Firpo’s contributions are not only within the realm of research of great impact, but also include training 79 scientists and facilitating the establishment of a world-class research group in Ethiopia. He has worked to improve international germplasm screening in Ethiopia. As a postdoctoral research associate, Firpo’s first assignment was to search for new sources of resistance to Ug99 in durum wheat, used for pasta, and related tetraploid wheat lines. That project took him to Ethiopia, where an international Ug99-screening nursery for durum wheat was established at Debre Zeit Research Center. He worked closely with researchers from the Ethiopian Institute of Agricultural Research (EIAR) and the International Maize and Wheat Research Center (CIMMYT) to improve the methodologies for screening and to provide hands-on training to researchers managing the international screening nursery. During a period of 10 years (from 2009 to 2019), he traveled to Ethiopia 21 times to evaluate stem rust reactions of US and international durum wheat germplasm and completed the screening of the entire durum collection (more than 8,000 accessions) from the USDA National Small Grains Collection.

Firpo’s research on sources and genetics of stem rust resistance led to discoveries of valuable genetic resistance in durum and other relatives of wheat. These sources of resistance have provided the needed diversity to ensure the development and sustainability of durable stem rust resistance.

With frequent epidemics and severe yield losses caused by stem rust in eastern Africa, establishing a functional rust pathology laboratory to support international screening, as well as to monitor and detect new virulences in the pathogen population, became a high priority for the international wheat research community. Utilizing the onground opportunities in Ethiopia, Firpo and his colleagues at the CDL and UMN enthusiastically participated in building up the rust pathology lab at the Ambo Plant Protection Center of EIAR. Firpo traveled to Ambo 11 times to provide hands-on training to staff and to develop cereal rust protocols to suit local conditions. He worked closely with colleagues at CDL, EIAR, and CIMMYT to secure and upgrade facilities, equipment and supplies to a standard that ensures reliable rust work will be carried out. As a result, the rust pathology lab at the Ambo Center became the only laboratory in eastern Africa, and one of a handful in the world, that can conduct high-quality race analysis of wheat stem rust samples and provide vital and necessary support for breeding global wheat varieties for rust resistance. Currently, the laboratory is playing a critical role in the global surveillance of the stem rust pathogen and supports wheat breeding efforts led by EIAR, CIMMYT, and the USDA.

Firpo has been passionate in supporting capacity building of human resources in Ethiopia and elsewhere. He has been eager to share his knowledge whenever he encounters an opportunity to do so. In addition to the direct training of the staff at the Ambo Center, Firpo accepted invitations to provide training lectures and hands-on field- and greenhouse-based workshops on rust pathology at three research centers in Ethiopia. He prepared training materials, delivered a total of 12 lectures and 10 practical sessions in three Ethiopia national workshops in 2014, 2015, and 2017. These workshops enhanced human resource development and technical capacity in ​Ethiopia in cereal rust pathology; participants included a total of 64 junior scientists and technical staff from nationwide research centers. Beyond Ethiopia, he was responsible for developing and implementing a six-week training program in cereal rust prevention and control for international scientists. This training program, under the aegis of the Stakman-Borlaug Center for Sustainable Plant Health in the Department of Plant Pathology, University of Minnesota, provided an experiential learning opportunity for international scientists interested in acquiring knowledge and practical skills in all facets of working with cereal rusts. The program trained 15 rust pathologists and wheat scientists from Ethiopia, Kenya, Pakistan, Nepal, Bhutan, Georgia, and Kyrgyzstan, ranging from promising young scientists selected by the USDA as Borlaug Fellows to principal and senior scientists in their respective countries. Many of these trainees have become vital partners in the global surveillance network for cereal rusts.

Working in collaboration with CDL and international scientists, Firpo has been closely involved in global surveillance of the stem rust pathogen, spurred by monitoring the movements of, and detecting, new variants in the Ug99 race group. Since 2009, he and the team at the CDL have analyzed 2,500 stem rust samples from 22 countries, described over 35 new races, and identified significant virulence combinations that overcome stem rust resistance genes widely deployed in global wheat varieties. Among the most significant discoveries were the identification of active sexual populations of the stem rust pathogen in Kazakhstan, Georgia, Germany, and Spain that have unprecedented virulence and genetic diversities. More than 320 new virulent types (or races) were identified from these sexual populations. Evolution in these populations will present continued challenges to wheat breeding. Research in race analysis has provided valuable pathogen isolates that are used to evaluate breeding germplasm to select for resistant wheat varieties and to identify novel sources of stem rust resistance.

A shortage of farm workers is driving the serious consideration by farmers and policymakers to replace traditional, labor-intensive puddled rice cropping (shown here), which leads to sizable methane emissions and profligate use of irrigation water, with the practice of growing rice in non-flooded soils, using conservation agriculture and drip irrigation practices.

A climate-smart remodeling of South Asia’s rice-wheat cropping is urgent

Written by Mike Listman on . Posted in Publications.

A climate change hotspot region that features both small-scale and intensive farming, South Asia epitomizes the crushing pressure on land and water resources from global agriculture to feed a populous, warming world. Continuous irrigated rice and wheat cropping across northern India, for example, is depleting and degrading soils, draining a major aquifer, and producing a steady draft of greenhouse gases.

Through decades-long Asian and global partnerships, the International Maize and Wheat Improvement Center (CIMMYT) has helped to study and promote resource-conserving, climate-smart solutions for South Asian agriculture. Innovations include more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations. Partners are recently exploring regenerative agriculture approaches — a suite of integrated farming and grazing practices to rebuild the organic matter and biodiversity of soils.

Along with their environmental benefits, these practices can significantly reduce farm expenses and maintain or boost crop yields. Their widespread adoption depends in part on enlightened policies and dedicated promotion and testing that directly involves farmers. We highlight below promising findings and policy directions from a collection of recent scientific studies by CIMMYT and partners.

Getting down in the dirt

A recent scientific review examines the potential of a suite of improved practices — reduced or zero-tillage with residue management, use of organic manure, the balanced and integrated application of plant nutrients, land levelling, and precise water and pest control — to capture and hold carbon in soils on smallholder farms in South Asia. Results show a potential 36% increase in organic carbon in upper soil layers, amounting to some 18 tons of carbon per hectare of land and, across crops and environments, potentially cutting methane emissions by 12%. Policies and programs are needed to encourage farmers to adopt such practices.

Another study on soil quality in India’s extensive breadbasket region found that conservation agriculture practices raised per-hectare wheat yields by nearly half a ton and soil quality indexes nearly a third, over those for conventional practices, as well as reducing greenhouse gas emissions by more than 60%.

Ten years of research in the Indo-Gangetic Plains involving rice-wheat-mungbean or maize-wheat-mungbean rotations with flooded versus subsoil drip irrigation showed an absence of earthworms — major contributors to soil health — in soils under farmers’ typical practices. However, large earthworm populations were present and active under climate-smart practices, leading to improved soil carbon sequestration, soil quality, and the availability of nutrients for plants.

Rebooting marginal farms by design

Using the FarmDESIGN model to assess the realities of small-scale, marginal farmers in northwestern India (about 67% of the population) and redesign their current practices to boost farm profits, soil organic matter, and nutritional yields while reducing pesticide use, an international team of agricultural scientists demonstrated that integrating innovative cropping systems could help to improve farm performance and household livelihoods.

More than 19 gigatons of groundwater is extracted each year in northern India, much of this to flood the region’s puddled, transplanted rice crops. A recent experiment calibrated and validated the HYDRUS-2D model to simulate water dynamics for puddled rice and for rice sown in non-flooded soil using zero-tillage and watered with sub-surface drip irrigation. It was found that the yield of rice grown using the conservation agriculture practices and sub-surface drip irrigation was comparable to that of puddled, transplanted rice but required only half the irrigation water. Sub-surface drip irrigation also curtailed water losses from evapotranspiration and deep drainage, meaning this innovation coupled with conservation agriculture offers an ecologically viable alternative for sustainable rice production.

Given that yield gains through use of conservation agriculture in northern India are widespread but generally low, a nine-year study of rice-wheat cropping in the eastern Indo-Gangetic Plains applying the Environmental Policy Climate (EPIC) model, in this case combining data from long-term experiments with regionally gridded crop modeling, documented the need to tailor conservation agriculture flexibly to local circumstances, while building farmers’ capacity to test and adapt suitable conservation agriculture practices. The study found that rice-wheat productivity could increase as much as 38% under conservation agriculture, with optimal management.

Nitrogen-Efficient Wheat Production Systems in the Indo-Gangetic Plains through Biological Nitrification Inhibition (BNI) Technology

Written by Bea Ciordia on . Posted in Uncategorized.

The Nitrogen-Efficient Wheat Production Systems in the Indo-Gangetic Plains through Biological Nitrification Inhibition (BNI) Technology project aims to raise awareness of the benefits of new nitrogen-efficient wheat production systems among stakeholders in India.

By introducing technologies that maintain crop yield and quality, even with a reduced amount of nitrogen fertilizer, this project will also lessen the footprint of food production systems and combat environmental degradation.

Rapid Point-of-Care Diagnostics for Wheat Rusts (MARPLE)

Written by Bea Ciordia on . Posted in Uncategorized.

MARPLE (Mobile And Real-time PLant disEase) diagnostics is a new innovative approach for fungal crop pathogen diagnostics developed by Diane Saunders’s team at the John Innes Centre.

MARPLE is the first operational system in the world using nanopore sequencing for rapid diagnostics and surveillance of complex fungal pathogens in situ. Generating results in 48 hours of field sampling, this new digital diagnostic strategy is leading revolutionary changes in plant disease diagnostics. Rapid strain level diagnostics are essential to quickly find new emergent strains and guide appropriate control measures.

Through this project, CIMMYT will:

  • Deploy and scale MARPLE to priority geographies and diseases as part of the Current and Emerging Threats to Crops Innovation Lab led by Penn State University / PlantVillage and funded by USAID’s Feed the Future.
  • Build national partner capacity for advanced disease diagnostics. We will focus geographically on Ethiopia, Kenya and Nepal for deployment of wheat stripe and stem rust diagnostics, with possible expansion to Bangladesh and Zambia (wheat blast).
  • Integrate this new in-country diagnostic capacity with recently developed disease forecasting models and early warning systems. Already functional for wheat stripe rust, the project plans to expand MARPLE to incorporate wheat stem rust and wheat blast.

Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar)

Written by Bea Ciordia on . Posted in Uncategorized.

The Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar) project aims to define the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains of Bangladesh, India and Nepal.

Home to 450 million people, this region has the world’s highest concentration of rural poverty and strong dependence on agriculture for food and livelihoods. Productivity remains low and diversification is limited due to poorly developed markets, sparse agricultural knowledge and service networks, inadequate development of available water resources, and low adoption of improved, sustainable production practices.

Rupantar builds on existing work and partnership networks to link research outputs and development goals through the demonstration of inclusive diversification pathways, definition of processes for scaling to the millions of smallholder farmers in the region, and generating a better understanding of the policies that support diversification.

Research objectives

  • Defining the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains.
  • Understanding the context for diversification in the Eastern Gangetic Plains.
  • Defining and implementing diversification pathways using collaborative and inclusive approaches.
  • Deepening understanding of the trade-offs and synergies associated with diversification pathways.
  • Engaging and communicating with change-makers to ensure outputs are used and integrated into independent programs.

Project outcomes

  • Demonstrated pathways for equitable and sustainable diversified food systems in the EGP.
  • Improved evidence-based policies for planning and development programs that promote diversification.
  • Self-sustaining diversification pathways that are owned by local partners and promoted without ongoing project support.

On April 26–29, 2022, researchers from Nepal participated in a workshop on the use of MARPLE Diagnostics, the most advanced genetic testing methodology for strain-level diagnostics of the deadly wheat yellow rust fungus. Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the John Innes Centre trained 21 researchers from the Nepal Agricultural Research Council (NARC) and one from iDE. The workshop took place at NARC’s National Plant Pathology Research Centre in Khumaltar, outside the capital Kathmandu.

“The need for new diagnostic technologies like MARPLE and the critical timing of the workshop was highlighted by the severe yellow rust outbreak observed this season in the western areas of Nepal,” commented Dave Hodson, Senior Scientist at CIMMYT and project co-lead. “Having national capacity to detect the increasing threats from yellow rust using MARPLE will be an important tool to help combat wheat rusts in Nepal”.

The yellow rust fungus can cause grain yield losses of 30–80 % to wheat, Nepal’s third most important food crop.

Current diagnostic methods for wheat rust used in Nepal are slow, typically taking months between collecting the sample and final strain identification. They are also costly and reliant on sending samples overseas to highly specialized labs for analysis.

MARPLE (Mobile and Real-time PLant disEase) Diagnostics is the first method to place strain-level genetic diagnostics capability directly into the hands of Nepali researchers, generating data in-country in near-real time, for immediate integration into early warning systems and disease management decisions.

“This is a fantastic opportunity to bring the latest innovations in plant disease diagnostics for the wheat rust pathogens to where they are needed most, in the hands of researchers in the field working tirelessly to combat these devastating diseases,” commented Diane Saunders, Group Leader at the John Innes Centre and project co-lead.

Suraj Baidya senior scientist and chief of the National Plant Pathology Research Centre at NARC noted the worrying recent geographical expansion of yellow rust in Nepal. “Due to global warming, yellow rust has now moved into the plain and river basin area likely due to evolution of heat tolerant pathotypes. MARPLE Diagnostics now gives us the rapid diagnostics needed to help identify and manage these changes in the rust pathogen population diversity,” he said.

The highly innovative MARPLE Diagnostics approach uses the hand-held MinION nanopore sequencer, built by Oxford Nanopore, to generate genetic data to type strains of the yellow rust fungus directly from field samples.

Beyond MARPLE Diagnostics, Saunders noted that “the workshop has also opened up exciting new possibilities for researchers in Nepal, by providing local genome-sequencing capacity that is currently absent.”

What’s next for MARPLE Diagnostics in Nepal?

Following the successful workshop, Nepali researchers will be supported by CIMMYT and the John Innes Centre to undertake MARPLE Diagnostics on field samples collected by NARC. “The current plan includes monitoring of yellow rust on the summer wheat crop planted at high hill areas and then early sampling in the 2022/23 wheat season,” Hodson noted.

“We were struck by the enthusiasm and dedication of our colleagues to embrace the potential offered by MARPLE Diagnostics. Looking forward, we are excited to continue working with our Nepali colleagues towards our united goal of embedding this methodology in their national surveillance program for wheat rusts,” Saunders remarked.

MARPLE Diagnostics is supported by the Feed the Future Innovation Lab for Current and Emerging Threats to Crops, funded by the United States Agency for International Development (USAID), the UK Biotechnology and Biological Sciences Research Council (BBSRC) Innovator of the Year Award, the CGIAR Big Data Platform Inspire Challenge, the Bill & Melinda Gates Foundation and the United Kingdom’s Foreign, Commonwealth and Development Office.

Researchers at the International Maize and Wheat Improvement Center (CIMMYT) have studied and witnessed that women, particularly in South Asia, have strongly ingrained and culturally determined gender roles.

While women play a critical part in agriculture, their contributions are oftentimes neglected and underappreciated. Is there any way to stop this?

On International Day of Women and Girls in Science, we spoke to Pragya Timsina about how women’s participation in agriculture is evolving across the Eastern Gangetic Plains and her findings which will be included in a paper coming out later this year: ‘Necessity as a driver of bending agricultural gender norms in South Asia’. Pragya is a Social Researcher at CIMMYT, based in New Delhi, India. She has worked extensively across different regions in India and is currently involved in various projects in India, Nepal and Bangladesh.

What is the current scenario in the Eastern Gangetic Plains of South Asia on gender disparities and women’s involvement in agriculture? Is it the same in all locations that your research covered?

Currently, traditional roles, limited mobility, societal criticism for violating gender norms, laborious unmechanized agricultural labor, and unacknowledged gender roles are among the social and cultural constraints that women face in the Eastern Gangetic Plains. Our research shows that while these norms exist throughout the Eastern Gangetic Plains, there are outliers, and an emerging narrative that is likely to lead to further bending (but not breaking, yet) of such norms.

Are there any factors that limit women from participating in agriculture? 

Cultural and religious norms have influence gender roles differently in different households but there are definitely some common societal trends. Traditionally, women are encouraged to take on roles such as household chores, childcare, and livestock rearing, but our research in the Eastern Gangetic Plains found that in specific regions such as Cooch Behar (West Bengal), women were more actively involved in agriculture and even participated in women-led village level farmers’ groups.

How or what can help increase women’s exposure to agricultural activities?

At the community level, causes of change in gender norms include the lack of available labor due to outmigration, the necessity to participate in agriculture due to a labor shortage, and a greater understanding and exposure to others who are not constrained by gendered norms. There are instances where women farmers are provided access and exposure to contemporary and enhanced technology advances, information, and entrepreneurial skills that may help them become knowledgeable and acknowledged agricultural decision makers. In this way, research projects can play an important role in bending these strongly ingrained gendered norms and foster change.

In a context where several programs are being introduced to empower women in agriculture, why do you think they haven’t helped reduce gender inequality?

Our study reveals that gender norms that already exist require more than project assistance to transform.

While some women in the Eastern Gangetic Plains have expanded their engagement in public places as they move away from unpaid or unrecognized labor, this has not always mirrored shifts in their private spaces in terms of decision-making authority, which is still primarily controlled by men.

Although, various trends are likely to exacerbate this process of change, such as a continued shortage of available labor and changing household circumstances due to male outmigration, supportive family environments, and peer support.

What lessons can policymakers and other stakeholders take away to help initiate gender equality in agriculture?

Although gender norms are changing, I believe they have yet to infiltrate at a communal and social level. This demonstrates that the bending of culturally established and interwoven systemic gender norms across the Eastern Gangetic Plains are still in the early stages of development. To foster more equitable agricultural growth, policymakers should focus on providing inclusive exposure opportunities for all community members, regardless of their standing in the household or society.

What future do the women in agriculture perceive?

Increasing development projects are currently being targeted towards women. In certain circumstances, project interventions have initiated a shift in community attitudes toward women’s participation. There has been an upsurge in women’s expectations, including a desire to be viewed as equal to men and to participate actively in agriculture. These patterns of women defying gender norms appear to be on the rise.

What is your take on women’s participation in agriculture, to enhance the desire to be involved in agriculture?

Higher outmigration, agricultural labor shortages, and increased shared responsibilities, in my opinion, are likely to expand rural South Asian women’s participation in agricultural operations but these are yet to be explored in the Eastern Gangetic Plains. However, appropriate policies and initiatives must be implemented to ensure continued and active participation of women in agriculture. When executing any development projects, especially in the Eastern Gangetic Plains, policies and interventions must be inclusive, participatory, and take into account systemic societal norms that tend to heavily impact women’s position in the society.
