This study investigates the optimal agricultural land use allocation and nitrogen application to arepresentative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis ata disaggregated level in order to capture the underlying heterogeneity of...

Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse agro-biodiversity impact of technology adoption might be partially counteracted by an...

A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

Agricultural crop production in Nigeria is mostly rain fed. Therefore any change in climatic factors such as changes in rainfall could alter crop yield. On the other hand prices of agricultural commodities give signals to producers over the type and quantity of commodity to produce. This study...

Organic and low-input farming practices are considered keystones for the conservation of biodiversity in semi-natural systems. Accordingly, attention to the assessment of the benefits stemming from these activities is increasing in order to provide a solid base for the adoption of...

This study investigates the optimal agricultural land use allocation and nitrogen application to a representative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis at a disaggregated level in order to capture the underlying heterogeneity of...

Replaced with revised version of paper 04/20/10.

In this paper, a dynamic optimization model was developed to simulate how farm-level realized price and profitability respond to yield change which was induced by climate change. Producers' acreage response was included in the dynamic model considering crop rotation effect. In the crop rotation...
