Information on the spatial distribution of poverty can be useful in designing geographically targeted rural poverty reduction programs. This paper uses recently released município-level data on rural poverty in Brazil to identify and analyze spatial patterns of rural poverty in the São...

This paper presents a linked hydro-economic model and uses it to examine the regional effects of water use regulations and product price changes on the agriculture of the São Francisco River Basin, Brazil. The effects of weather on surface water availability are explicitly addressed using the...

Policymakers, managers of water use associations, and many others in developing countries are considering policy actions that will directly or indirectly change the costs and availability of groundwater and surface water for agricultural users. While in many cases such actions may bring about...

We overview the roles of production structure models in measuring fisheries' productive performance to provide policy-relevant guidance for fishery managers and analysts. In particular, we summarize the literature on the representation and estimation of production structure models to construct...

Applications of nonlinear dynamic tools for studying air pollution are gaining attention. Studies on ozone concentration in urban areas have reported the presence of low-dimensional deterministic natures and thus the possibility of good predictions of air pollution dynamics. In light of these...

Farming practices, including tillage, cover cropping and residue management can have profound effects on the efficiency of irrigation practices. The effects of three field management practices (FMPs) standard tillage and winter-fallow (ST), standard tillage and winter-cover crop (STCC), and...

Rates of obesity among adults and children in the U.S. are soaring, with potentially huge private and social costs. Increasing attention is being paid to agricultural policies as both the culprits through their perceived roles in reducing the relative prices of energy-dense foods, and as the...

Green Revolution technologies were developed and promoted in the 1960s in response to alarm about impending famine in Asia. By boosting food supplies and fostering development, the technologies were expected to create "breathing space" for completing demographic transitions there. This paper...
