Transformation of the Aquaculture Value Chain in Kenya

The Kenyan aquaculture sector has undergone a profound structural transformation over the last decade, evolving from a subsistence-based activity into a sophisticated commercial ecosystem. This growth is most evident in the cage-based segment of Lake Victoria, which saw an explosive 1,300-fold increase in production volume between 2014 and 2024.

High Value Crop Commercialization and Women’s Empowerment in Sub-Saharan Africa: Panel Insights Reinforced by Double Machine Learning and Quasi-Experiments

We examine how agricultural commercialization relates to women’s empowerment across Ethiopia, Malawi, Tanzania, Uganda, and Nigeria using LSMS-ISA household panels (2010–2020), a modified A-WEAI (5DE), two-way fixed effects, Double Machine Learning, and propensity-score matched difference-in-differences. Entry into markets (extensive margin) is consistently associated positively with empowerment where identification is strongest: PSM-DiD shows noticeable gains when households begin selling any crops—especially in Ethiopia, Malawi, Tanzania and Nigeria—and positive correlations when existing sellers add cash crops to sales in Malawi (Ethiopia marginal).

Towards inclusive and sustainable vegetable value chains in Odisha

The Hidden Middle—the segment of agrifood systems that connects farmers to consumers through aggregation,
storage, logistics, and processing—has long been overlooked in both research and policy. Yet this is where most
value addition, employment, and efficiency gains actually occur. When midstream actors function well, food
systems are more resilient, markets are more stable, and small producers gain predictable access to buyers and
inputs. When they do not, costs rise, losses increase, and opportunities for inclusive growth dissipate.

Social Learning and Peer Influence in Smallholder Commercialization

This paper examines how peer behavior influences small-scale producers’ (SSPs) decisions to purchase inputs and sell outputs in six sub-Saharan African countries. Using comparable nationally representative panel data and a correlated random effects framework, we assess the extent and shape of social interactions driving input and output market participation.
