On the Economics of US Agricultural Policy
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This paper presents an economic analysis of US agricultural policy, building on a modified version of Gardner's efficient redistribution. We argue that agricultural policy is motivated as an attempt to implement an efficient redistribution scheme that redistributes income toward farmers who, as a group, have been adversely affected by ...

Comparison of potential and real erodibility of soil by wind
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 Areas the most susceptible to wind erosion were chosen for the comparison of potential and real erodibility of soil by wind. All the areas are located in the Southern Moravia, the south-east of the Czech Republic.

The Effects of Wind Erosion Depending on Cropping System and Tillage Method in a Semi-Arid Region
Agronomy, 2020 Wind erosion is a major environmental problem in arid and semi-arid regions, where it has significant impacts on desertification and soil degradation. To understand the effects of cropping systems and tillage methods on the reduction of soil wind erosion,

Effects of recreation and environment upon the erosion of mountain footpaths in the Lake District National Park. [PDF]
, 1979 Increasing numbers of walkers in mountain areas have led to concern about the deterioration of footpaths through the erosion of vegetation and soil. Sites were established to monitor path erosion by repeated measurements of cross sections.

American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

The prevention of wind erosion in agriculture
, 1977 The wind erosion is a problem over more than 80 000 hectares in the Netherlands. The damage in wind erodible areas is on the average at least 150 Dfl. per hectare per year.
