This brief presents an overview of EPAR’s previous research related to gender. We first present our key takeaways related to labor and time use, technology adoption, agricultural production, control over income and assets, health and nutrition, and data collection. We then provide a brief overview of each previous research project related to gender along with gender-related findings, starting with the most recent project. Many of the gender-related findings draw from other sources; please see the full documents for references. Reports available on EPAR’s website are hyperlinked in the full brief.
This brief presents an overview of EPAR’s previous research on nutrition and food security and outlines summaries and key findings from 15 technical reports and research briefs. Key findings are drawn from our own original analyses as well as from other sources, which are cited in the individual reports. We also include appendices briefly summarizing EPAR’s research on health and climate change, topics somewhat related to nutrition and food security, and EPAR’s confidential work on nutrition and food security.
This brief summarizes the evidence base for various types of commonly-used time use measurements, lists categories of time use as identified by major organizations and reports, and identifies studies finding significant impacts of interventions designed to reduce specific time constraints. The various approaches to time use measurement method each have different limitations (cost, timing, seasonality, susceptibility to recall bias, etc.), which may have implications for data analysis. The choice of how to measure time use may be particularly important for analyzing women’s time use. For example, limiting respondents to one activity per time slot when measuring daily time allocation may underestimate women's productivity or time allocations, as they are more likely than men to conduct simultaneous activities, such as childcare along with other activities.
This four-part analysis describes the current suite of food security measures, then analyzes the respective relationships between food security and poverty, GDP, and crop yields using findings from in-depth literature reviews. Food security measures are criticized for inaccurately characterizing food security at individual, household, and national scales, yet guidelines exist to prescribe a food security measure for a given situation. Some authors see the potential of a combination of indicators that apply at different scales rather than a single, universal food security measure. Limited literature exists on the relationship between food security and poverty, GDP, or crop yields. The relationship between food security and poverty is particularly challenging because neither term has a consistent definition, and the limited literature suggests a lack of consensus among experts. Little empirical research exists on the relationship between food security and GDP, though studies generally note an association between the two Studies that evaluate food security and crop yields provide limited evidence that the two are associated, though many studies use measures of crop yield as food security indicators and vice versa. More research is needed to establish whether there are preferred food security measurement tools for specific scales and situations, and to further explore the relationship between food security and poverty, GDP, and crop yields.
Yam is a major staple in West and Central Africa and an important supplementary food in East Africa. In Sub-Saharan Africa (SSA), virtually all yams are produced for human consumption, with women responsible for processing yams for consumption. This brief provides an overview of the role of women in yam production, and provides a framework for analyzing barriers to women and technology’s impact on women throughout the cropping cycle. We find that though yam was traditionally considered a man’s crop, it is clear that women farmers contribute greatly to yam cultivation, especially during weeding, harvesting, and processing. Propagation of improved varieties with resistance to pests and diseases like yam mosaic disease has great potential to benefit women farmers. Increased yields and lower post-harvest losses will increase household food security. However, because yams extract high amounts of nutrients from the soil, soil and land management techniques are necessary to ensure future gains in yield. Women’s groups serve as potential venues for dissemination of new yam cultivation and processing technologies. Additionally, women’s groups can undertake new propagation techniques as income generating activities. Women farmers need increased extension efforts to fully benefit from technology improvements.
The millets, a group of small-seeded grasses indigenous to Africa, are an extremely important staple food in resource-poor regions of Sub-Saharan Africa (SSA). Millet requires few inputs, suffers less from insect pests and disease than other grains, and can tolerate areas even too hot and dry for sorghum. These characteristics make millet an essential component of food security and risk management strategies for many Africans, though both consumption and production per capita of millet has declined in the last 20 years as farmers have shifted toward maize and rice production. This brief provides an overview of the role of women in millet production, and provides a framework for analyzing barriers to women and technology’s impact on women throughout the cropping cycle. We find that the shift away from millet may result in poorer nutrition and increased time burden for women where they must find alternatives to millet fuel, but that little is known about these consequences. Investing in improved varieties that account for both men’s and women’s preferences, introducing labor-saving technology, and increasing market access all have the potential to increase millet’s production and consumption on the continent.
Sorghum grows well in arid and semi-arid agroecological zones and is thus one of the most important cereals in the Sahel region of Sub-Saharan Africa (SSA). Both men and women cultivate sorghum primarily for household consumption, though women are nearly exclusively responsible for post-harvest production of the grain, including brewing and selling sorghum beer. This brief provides an overview of the role of women in sorghum production, and provides a framework for analyzing barriers to women and technology’s impact on women throughout the cropping cycle. We find that improved sorghum varieties have the potential to greatly increase sorghum yields in SSA by alleviating cultivation threats from striga, pests, and drought. Because women farmers are the primary cultivators of sorghum, they stand to benefit most from these improved varieties. However, low adoption rates of new technologies suggest that more resources need to be dedicated to extension efforts and informal seed distribution networks that include women farmers. Post-harvest processing of sorghum is both time and labor intensive and is causing many women farmers to transition to maize or rice. Finally, increased demand for sorghum as a biofuel stock may not translate into gains for women farmers as expected, because women farmers tend to lack input resources, and women farmers often lose control over crops as they transition to cash crops.
In Sub-Saharan Africa (SSA), maize alone provides an estimated one third of the mean caloric intake and in 2006, accounted for 21% of all harvested food crops, making it the single most important food crop in the region. In addition, maize is also used as feedgrain and fodder, adding to its importance in integrated smallholder farming systems in SSA. In general, women are the main producers of staple crops such as maize. Understanding the gender dimensions of maize is particularly challenging because maize is used as both a subsistence and cash crop, and may be considered either a male or female crop depending on farmer circumstances and how the particular variety is promoted. This brief provides an overview of the role of women in maize production, and provides a framework for analyzing barriers to women and technology’s impact on women throughout the cropping cycle. We find that lower access to factors such as extension access, education level, land, and labor contribute to female’s lower rate of maize technology adoption. Understanding women’s disproportionate access to resources and how improved technology may change allocation of resources should help project developers improve both women’s and men’s productivity.
In the last half century, the increased opportunity cost of women’s time in Sub-Saharan Africa (SSA) has led to remarkable growth in the consumption of wheat and other easy-to-prepare staples. Wheat tends to be grown and processed on a large scale in SSA. Ethiopia (SSA’s largest producer of wheat) is the exception, where smallholders are responsible for 76% of total production. This brief provides an overview of the role of women in wheat production, and provides a framework for analyzing technology’s impact on women throughout the cropping cycle. We find that many constraints exist to adoption of improved wheat varieties by women. A review of improved wheat variety adoption in the developing world found that it takes 5-10 years after breeding to the release and another 5-10 years for full adoption, but this length of time has been found to be reduced with the use of participatory breeding, varietal selection, and gender analysis. By including women in every stage of development and planning of new technologies, programs can become more aware of the needs of targeted women and therefore, increase adoption rates and improve the productivity of men and women in wheat farming.
This brief presents an initial examination of the possibility of using Disability Adjusted Life Years (DALYs) as a way to evaluate agricultural interventions. We review DALYs, their formulation, and the data necessary to compute values. A review of relevant literature suggests that to use DALYs as an evaluative tool, an agricultural intervention must be tied to a specific disease, and from there, impacts on DALYs can be assessed.
