The Legume-based Agroecological Intensification of Maize and Cassava Cropping Systems in Sub-Saharan Africa (LEG4DEV) project aims to promote scaling of legume-based agroecological intensification of smallholder maize and cassava cropping systems in sub-Saharan Africa for water-food-energy nexus sustainability that enables food security and livelihood resilience.
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 womenâs 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: âNecessity as a driver of bending agricultural gender norms in South Asiaâ. 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 womenâs 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?Â
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 womenâs 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 havenât 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 womenâs 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.
In sub-Saharan Africa, smallholder production is characterized by low agricultural productivity which is often cited as a major factor of  food insecurity in the region. Recent research from multiple countries in the region suggests that average maize yields of around 1.7 t/ha in 2010 must increase to 6.8 t/ha to meet estimated demand in 2050. To achieve this, per-hectare maize output must grow by about 3.5% per year. Although addressing this challenge seems daunting, estimates suggest that such high yields are technically feasible. However, a shared understanding of the investments and policies required remain elusive.
Under the Taking Maize Agronomy to Scale in Africa (TAMASA) project, scientists from Wageningen University and the International Maize and Wheat Improvement Center (CIMMYT) conducted research on this question, using uniquely detailed farm surveys which provide integrated information about smallholdersâ agronomic practices and farm management, soil health and other biophysical characteristics, as well as socioeconomic and other characteristics of farm households.
Decomposing yield gaps
Yield gaps for rainfed crops are defined as the difference between the water-limited yield potential and the actual yield observed in farmersâ fields. One framework to explain yield gaps decomposes the yield gap into efficiency, resource and technology components (Figure 1).
The study disaggregated maize yield gaps in Ethiopia based on field level and farming systems information (Figure 2), which helps to consider the variation in biophysical and socio-economic conditions observed in the country.
Major drivers of yield (and yield gap) outcomes in Ethiopia
The study showed that income from non-farm sources, value of productive assets, education and shorter plot distance from home reduced the efficiency yield gap. The resource yield gap was attributed to sub-optimal input use, specifically of pesticide and nitrogen. The technology yield gap comprised the largest share of the total yield gap, mostly due to limited use of fertilizer and improved varieties and not using the right type and placement of fertilizers and of improved seeds
The investigation further showed that crop residue and weeding frequency affected maize yield only when nitrogen was applied. In a related study, the authors also showed that maize yield reponse to fertilizer application was dependent on other inputs, specifically type of maize variety, manure application and high rainfall implying the need to integrate agricultural technologies in order to improve and sustain the maize productivity. The authors conclude that targeted but integrated policy design and implementation is required to narrow the overall maize yield gap and improve food security.
“Disaggregating and explaining maize yield gaps is essential to identify potential pathways that can narrow the yield gaps,” said Banchayehu Assefa from CIMMYT. “This can help guide policy and investments to be more effective at raising smallholder productivity.”
How to improve fertilizer profitability
Modern maize varieties and mineral fertilizers use have been increasing over time and are believed to be among the factors behind the maize yield improvements observed in Ethiopia. However, maize yield response to fertilizer depends on other inputs and management factors and higher fertilizer application rates may not always lead to higher profitability. Using the details of management decisions and biophysical and marketing context, the authors estimated a maize yield response function and evaluated fertilizer yield responses and economic profitability of fertilizer investments by smallholder maize producers. They found that maize yield response to fertilizer was variable with an average value of 7.3 kg maize/ kg N, and it varied from -9 to 18 kg maize /kg. The degree of response was positively affected by phosphorus input and type of maize variety, and negatively by manure input and high rainfall. The key pathways identified to increase the profitability of nitrogen fertilizer use by smallholder maize producers are: improving yield responses with better management (e.g. use of improved maize varieties, complementary use of phosphorus where appropriate); addressing risk aversion (e.g. via crop insurance) in order to strengthen economic incentives for fertilizer investments; enabling the delay of crop sales to take advantage of higher output prices (possibly through expanded access to storage facilities and/or post-harvest loans to alleviate liquidity needs); and improving farm gate price ratios through improved access to markets.
Implications and further research
Even though maize yields have improved recently, under existing management practices smallholdersâ maize yield still falls far below the water-limited potential yield. This urges revising the maize sector in terms of input provision, extension services and output markets. Fertilizer use was highly variable and maize response to fertilizer use depended on other management choices. The study suggests that integrated management practices that work for specific conditions need to be identified, instead of sticking to blanket policy and management recommendations.
This work further points at the importance of additional detailed empirical research on the role of agronomic management practices, to decrease yield gaps. Studying the constraining factors that hinder timely input provision to the farmers might also help to improve input use and hence productivity. In addition, maize prices are too low to advance maize commercialization. Investigating potentials and constraints along the maize value chain might help to improve market participation.
