We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade.

We show empirically using panel data at the plot and farm level and based on a model incorporating supervision costs, risk, credit-market imperfections and scale-economies associated with mechanization that small-scale farming is inefficient in India. Larger farms are more profitable per acre, more mechanized, less constrained in input use after bad shocks, and employ less per-acre labor than small farms.

Human activities have exerted small to large scale changes on the hydrological cycle. The current scenario regarding groundwater resources suggests that globally there is a water crisis in terms of quantity (availability) and quality. Therefore there is a great need for the assessment and monitoring of quality and quantity of groundwater resources at local level. This paper presents a case study of the lower Shiwalik hills, in Rupnagar, Punjab, India, to trace land-use and land-cover changes during the past 17 years, with an emphasis on groundwater quality and quantity.

Developing countries are currently attempting to fulfill these demands by evolving new IPR regimes that simultaneously protect the rights of breeders and farmers. What are the possible implications of establishing such a system of multiple rights on the utilization and exchange of genetic resources among various actors?

This paper explores the feasibility of adopting an integrated economic approach to raise farmers’ tolerance of the presence of elephants on their farming lands. Responses to this approach were sought from a sample of farmers in the areas affected by human elephant conflict in the northwestern province of Sri Lanka. Results from a contingent valuation survey of their willingness to pay for a scheme to conserve elephants are also reported.

I evaluate India's transition from an inward-oriented development strategy to greater participation in the world economy. While tariff rates have decreased significantly over the past decade, India is still one of the more autarkic countries. Despite improvement over the past in export performance, India continues to lag behind its South- and East Asian neighbors. Second, official debt flows have been largely replaced by foreign direct investment (FDI) and portfolio investment in the 1990s. India's ability to attract FDI would be greatly enhanced by further reforms.
