Adaptation to climate change in Sub-Saharan agriculture: assessing the evidence and rethinking the drivers

In this paper, after a review of the evolution of the literature on climate change economics in agriculture, I present some evidence of the impact of different moments of the distribution of rainfall on farmers risk aversion.

It is found that while more rainfall is negatively associated with the probability of observing risk aversion, rainfall variability is positively correlated. This result highlights an important behavioural dimension of climatic factors.

This study investigates the impact of package adoption of inorganic fertilizers and improved maize seed varieties on yield among smallholder households in Kenya. We used a quasi-experimental difference-in-differences approach combined with propensity score matching to control for both time-invariant and unobservable household heterogeneity.

Cartels and Rent Sharing at the Farmer–Trader Interface: Evidence from Ghana’s Tomato Sector

Submitted by Salvatory Macha on

Itinerant traders provide an important route for West Africa’s farmers’ to get their perishable produce rapidly to the distant urban markets. But these farmers often accuse the traders of offering “unfairly” low prices while preventing direct access to these markets.

Integrating soil science into agricultural production frontiers

Submitted by Anonymous (not verified) on

This paper integrates soil science variables into an economic analysis of agricultural output among small-scale farmers in Kenya's highlands. The integration is valuable because farmers’ choice of inputs depends on both the status of the soil and socioeconomic conditions. The study uses a stochastic production frontier in which the individual farm's distance to the frontier depends systematically on individual factors.
