Impacts of climate‐smart crop varieties and livestock breeds on the food security of smallholder farmers in Kenya
EfD Authors:
AbstractThis paper analyses the impact of climate-smart agriculture (CSA) technologies on household dietary diversity and food insufficiency as indicators of food and nutrition security in Kenya. Using a combination of Propensity Score Matching and endogenous treatment effect approaches, we found that adoption of stress-tolerant varieties of several crops (such as bean, pigeon pea, cowpea, maize and sorghum) improved household dietary diversity score by 40% and reduced food insufficiency by 75%.

Scaling smallholder tree cover restoration across the tropics
EfD Authors:
Restoring tree cover in tropical countries has the potential to benefit millions of smallholders through improvements
in income and environmental services. However, despite their dominant landholding shares in many
countries, smallholders’ role in restoration has not been addressed in prior global or pan-tropical restoration
studies. We fill this lacuna by using global spatial data on trees and people, national indicators of enabling
conditions, and micro-level expert information. We find that by 2050, low-cost restoration is feasible within 280,
What can we learn about the natural disasters and multidimensional poverty link for artisanal fishery in Chile?
EfD Authors:
This article examines the connection between household poverty and natural disasters in Chile using a multidimensional analysis of poverty. Rather than using household income as a single poverty indicator, we implement a multidimensional poverty index, which measures poverty in four dimensions: work and social security, housing, health and education. This study helps reduce the limited knowledge of the impact of the 2010 earthquake and tsunami on household poverty in Chile, separating those events as different but related shocks.
Biomass Development and Fishers’ Vulnerability in Nigeria: Evidence from a Survey Dataset
EfD Authors:
/Biomass decline is a vital threat for small-scale fisheries, but lack of data affects our ability to understand both biomass development and fishers’ adaptation. This study contributes to the literature on cost-effective, survey-data-based methods in data-poor and development-oriented settings. Based on original survey data from Nigeria, we find that 58% of respondents perceive a decline in fish abundance, in particular top-predator biomass. However, we also find signs of strategic behavior by respondents.
Soil Conservation Practices and Neighborhood Effects – How Sustained are the relationships?
EfD Authors:
Key findings
Soil conservation activities (i.e., mixed cropping) in the south-south and northwest regions of the country in 2015 are influenced by a high prevalence of neighbours’ activities in 2012. Similarly, low prevalence of soil conservation activities in the middle belt of the country is correlated with similarly low activity levels of farmers’ neighbours in the preceding period.
Farmers with high (low) legumes cultivation in 2015 were surrounded by other farmers with similarly high (low) cultivation in 2012.
