Suboptimal diets are a major risk factor for avoidable death and disease in low- and middle-income countries. Evidence shows that some foods or food components (e.g., processed red meat, saturated fat, salt, sugar) significantly elevate the risk of noncommunicable diseases and mortality, while others protect health (e.g., vegetables, fruits, pulses, nuts/seeds, fish, whole grains—referred to […]
Understanding the production of “protective” foods in East Africa: A cross-country analysis of drivers and policy options
Supply chains for nutritious (“protective”) foods in Africa south of the Sahara are often poorly developed, especially for perishable crops that are vulnerable to wastage. We used LSMS-ISA surveys and geographic information system (GIS) data to explore which factors predict production patterns of four protective food crops (pulses, nuts and seeds, vegetables, and fruits) relative […]
A review of evidence on gender equality, women’s empowerment, and food systems
Achieving gender equality and women’s empowerment in food systems can result in greater food security and better nutrition, and in more just, resilient, and sustainable food systems for all. This paper uses a scoping review to assess the current evidence on pathways between gender equality, women’s empowerment, and food systems. The paper uses an adaptation […]
How accurate are yield estimates from crop cuts? Evidence from smallholder maize farms in Ethiopia
Agricultural statistics and applied analyses have benefitted from moving from farmer estimates of yield to crop cut based estimates, now regarded as a gold standard. However, in practice, crop cuts and other sample-based protocols vary widely in the details of their implementations and little empirical work has documented how alternative yield estimation methods perform. Here, […]
Mismatch between soil nutrient requirements and fertilizer applications: Implications for yield responses in Ethiopia
Lack of accurate information about soil nutrient requirements coupled with limited access to appropriate fertilizers could lead to mismatch between soil nutrient requirements and fertilizer applications. Such anomalies and mismatches are likely to have important implications for agricultural productivity. In this paper we use experimental (spectral soil analysis) data from Ethiopia to examine farmers’ response […]
