Effects of Bt Cotton in India During the First Five Years of Adoption AgEcon
Sadashivappa, Prakash; Qaim, Matin.
While previous research has analyzed the impacts of Bt cotton in India, most available studies are based on one or two years of data only. We analyze the technology’s performance over the first five years of adoption, using panel data with three rounds of observations. On average, Bt adopting farmers realize pesticide reductions of about 40%, and yield advantages of 30-40%. Profit gains are in a magnitude of US $60 per acre. These benefits have been sustainable over time. Farmers’ satisfaction is reflected in a high willingness to pay for Bt seeds. Nonetheless, in 2006 Indian state governments decided to establish price caps at levels much lower than what companies had charged before. This intervention has further increased farmers’ profits, but the impact...

Prospects for climate friendly peatland management – Results of a socioeconomic case study in Germany AgEcon
Schaller, Lena; Kantelhardt, Jochen.
In the current debate on climate protection, agricultural production has become a focal point of interest. This study introduces the climate effectiveness of agricultural management of peat-soils. Agriculture on peatland demands a water-level drawdown that causes aerobe degradation of the soils. The resulting trace-gas emissions have a negative impact on the greenhouse-gas balance. In Germany more than 80% of peatland is used agriculturally; the resulting emissions account for 2.3 – 4.5% of Germany’s overall emission. Climate-friendly peatland management strategies, however, demand enhanced groundwater tables and decreased land-use intensity. With regard to agricultural income, severe economic consequences are to be expected. Against this background we...

Reshaping agricultural peatland use climate friendly in selected German regions AgEcon
Schaller, Lena; Kantelhardt, Jochen; Hübner, Rico; Freibauer, Annette; Droesler, Matthias.
About 30 percent of the world’s soil carbon is stored in peat soils. Peatland’s functional principle of carbon storage greatly depends on management strategies. Therefore agricultural peatland use becomes a focal point of interest in the current debate on climate protection. Agricultural management demands a drawdown of the water-level that causes aerobe degradation of the soils, as well as trace-gas emissions which have a negative impact on greenhouse-gas balance. Climate-friendly peatland management strategies, however, demand enhanced groundwater tables and decreased land-use intensity. Against this background we analyse ways of re-organising agricultural peatland use within a case study located in Germany, where intensive peatland use accounts for 2.3...
