Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...

There is lack of consensus in the literature on the impact of contract farming on the welfare of smallholder farmers. Some authors argue that contact farming improves access to markets hence income, while others view contract farming as an avenue by which large corporations exploit smallholder...

Risk is a central issue in rural areas that affects many different aspects of people’s livelihoods in the developing world. Unless well managed, risks in agriculture can slow development and hinder poverty reduction. Farmers’ perceptions of and responses to risk are therefore...

To develop weather insurance, GROUPAMA builds a general model of agronomic crop yielddensity function. This approach is applied for cereal, industrial products, wine and fruits.From the density function, weather risk premium is computed. The wine-producing practicesdisturb our approach of risks....

Recent academic discussion regarding crop insurance in developing and transition countries has focused on weather index insurance. But empirical analyses of such schemes based on farm level data cannot be found in the literature, though this insurance type shows clear advantages compared to...

Index-based weather insurances are innovative tools for mitigating weather risks in agriculture.Several donor agencies and development organisations are investing substantially topropagate these programmes in developing countries. However, often due to high basis risks,these products mitigate...

California specialty crop growers are exposed to extreme price volatility, as well as considerable yield volatility caused by fluctuations in temperature, precipitation, and other specific weather events. Weather derivatives do provide a promising market-based solution to managing risks for...

The EPA has imposed mandatory refuge requirements for Bt crops to prolong the efficacy of Bt. Growers have no economic incentive to plant the required refuge because refuge crops are on average less productive and more risky. This paper evaluates refuge insurance—insurance thatpays indemnities...
