    Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops.

    More than three-quarters of Mexico's coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico's shade coffee areas is increasingly being cleared to make way for subsistence agriculture, a direct result of the unprecedented decline of international coffee prices over the past decade.

    There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry.

    Increasing land degradation and concomitant low agricultural productivity are important determinants of rural poverty in the hillside areas of Honduras. Using data at the levels of the farm household, parcel and plot, we develop an econometric modeling framework to analyze land management decisions and their impact on crop productivity. Our econometric model allows for endogenous household decisions regarding livelihood strategy choice, use of labor and external inputs, and participation in organizations.

    A household-level switching regression model is implemented to examine potential selectivity bias for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. In the presence of selectivity bias, separate stochastic production frontiers are estimated for low and high adopters. The main results indicate that households with higher levels of investments in soil conservation show higher average TE than those with a lower level of investments. Constrains in the rural land and credit markets are likely explanations for these differences.

    This paper presents an econometric analysis of land-cover change in western Honduras. Ground-truthed satellite image analysis indicates that between 1987 and 1996, net reforestation occurred in the 1,015.12 km2 study region. While some reforestation can be attributed to a 1987 ban on logging, the area of reforestation greatly exceeds that of previously clear-cut areas. Further, new area was also deforested between 1987-1996. Thus, the observed land-cover changes most likely represent a complex mosaic of changing land-use patterns across time and space.

    We evaluate the impact of agricultural land market liberalization policies in Latin America by empirically examining the degree to which the reforms have broken down the dependence of operational area on owned area. We use panel data sets from Honduras and Peru to estimate the relationship between operational and owned land holdings for pre and post reform periods.

    This study evaluates technical efficiency (TE) levels for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. To correct for potential self-selectivity bias a household-level switching regression framework is implemented to estimate separate stochastic production frontiers for the two groups of households under analysis. The main results indicate that a systematic difference exists between the two studied groups.

    The growth in federal conservation programs has created a need for policy modeling frameworks capable of measuring micro-level behavioral responses and macro-level landscape changes. This paper presents an empirical model that predicts crop choices, crop rotations, and conservation tillage adoption as a function of conservation payment levels, profits, and other variables at more than 42,000 agricultural sites of the National Resource Inventory (NRI) in the Upper Mississippi River Basin.

    In this paper we discuss the principal results of participatory surveys that were conducted between June 2001 and May 2002 in 95 communities (villages) in the rural hillside areas in Honduras. The principal objectives of the study were to determine the main income earning strategies at the community level; identify the most important determinants of these strategies; and analyze the principal factors that determine the use of conservation technologies and investments.
