The individual farmer in a developing country has little incentive to care about the public good properties of on-farm biodiversity in the form of different crop varieties. There is a common assumption that, because of this, farmers will tend to maintain too little biodiversity on their farms.

Since the beginning of the decade, climate resilient green economy strategies have been proposed in many African countries. One of the pillars of the strategies is the adoption and diffusion of various climate smart agricultural practices for improving crop and livestock production and farmer income while reducing greenhouse gas emissions. The effects of these innovations on household nutritional security, including gender-differentiated nutritional status, have hardly been analyzed.

The aim of this paper is to study the association between weather shocks (droughts and floods) and agricultural market performance in Mozambique. To do so, we employ a dyadic regression analysis on monthly maize prices, transport costs, and spatial identification of markets as well as droughts and flooded areas. Our estimates show that, while a drought reduces price differences between markets, price dispersion increases during flood periods, an effect that is mainly driven by increases in transport costs.
