Agricultural land use and the management of agricultural lands in Ghana as evidenced fromfarmer practices have been analysed using descriptive and regression analysis. The analysisshows that different land management practices affect crop yields differently in the differentecological zones.
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.
Vast areas of forests in North‐eastern Ethiopia have been replaced by cropland, shrub land or grazing areas. Thus, information about how vegetation composition and structure varies with disturbance is fundamental to conservation of such areas.
In this paper we present an application of aerial remote sensing to the analysis of spatial information in a mountainous area of central Italy by applying texture measures and landscape indices.
