    Abstract Agricultural systems are highly sensitive to climate change. Most studies focus on the effect of heat and water availability on crop yields, but little is known about the impact of changes in intra-seasonal climate variability (particularly challenging in mountain regions). Also, beyond the effect on crop yields –mostly focused on single cropping systems and major world crops- little analysis has been done on more complex, diversified and low-input cropping systems like those prevalent in the Andean region. This study investigates whether Andean farmers respond to increasing climate variability by increasing crop diversity (measured by intercropping and crop diversification indices) and by switching to crops which better tolerate heterogeneous environmental conditions. Since previous studies show that crop diversification fosters resilience of agricultural systems, decreasing crop portfolio diversity in an increasingly variable environment may challenge farms sustainability. The data used in the analysis combines district-level socio-economic information from two agrarian censuses (1994 and 2012) with district-level climate estimates of mean temperature, temperature range and precipitation (averages for periods 1964–1994 and 1982–2012). Based on fixed effects models that allow for sub-region parameter heterogeneity, I find that an increase in intra-seasonal climate variability leads farmers in colder areas (

    Summary Using a recursive optimization model, we analyze how the incorporation of charcoal production by pioneer farmers in the Peruvian Amazon rainforest would affect household net returns and the rate of deforestation at the early stage of forest colonization. Because charcoal production diverts scarce dry-season labor from land clearing for agriculture, deforestation by pioneer farmers may be slower. The model predicts that after 10 years, a representative pioneer farmer who produces charcoal would earn 17% higher net income and clear 17% less forested area. A sensitivity analysis predicts that any additional labor would be chiefly devoted to charcoal production, reinforcing the conservation effect.

    Authors: Douglas Horton;

    Abstract A number of studies are being conducted to assess the impacts of international agricultural programs. This “second generation” of impact studies can draw on earlier assessments of the production impacts of new, high-yielding rice and wheat varieties, particularly in Asia. New approaches and new data are needed, however, to assess the production impacts of other types of new technology (e.g., pest control methods, seed systems, and post-harvest technology) that are used with other crops and livestock, particularly in Africa and Latin America. Innovative study approaches are also needed to assess the institutional impacts of international programs. Given the high degree of institutional interdependence which characterizes agricultural research and extension it is inappropriate to attribute production impacts at the farm or consumer levels to specific international programs, as has sometimes been done. As an alternative to the narrow production economics framework employed in most previous impact studies, an interdisciplinary approach is outlined.
