    Various forms of coastal landuse covering study site (46,785.69 hectares) were observed to underwent changes as evidently detected between satellite images sensed in 1994 and 2001 at the Banten Bay. It was important to identify what these changes were. Therefore, appropriate change detection must be selected. The image preprocessing step involved removing errors from raster data. This was done by performing basic processes, such as, radiometric correction, geometric correction and image calibration.

    Net farm income for all representative farms in 2014 is projected to be lower than in 2004. Low-profit farms, which comprise 25% of the farms in the study, may not have financial resiliency to survive without off-farm income. Costs are projected to increase faster than yields, which will pressure net farm income downward. Cropland prices and cash rental rates are projected to increase slightly in all regions. Debt-to-asset ratios for most farms will decrease slightly throughout the forecast period.

    More than three-quarters of Mexico's coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico's shade coffee areas is increasingly being cleared to make way for subsistence agriculture, a direct result of the unprecedented decline of international coffee prices over the past decade.

    There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry.

    We offer a practical test of local government effectiveness in the provision of public services. Building on the work of Brueckner (1979, 1982, 1983) and Henderson (1990, 1995) we offer a property value maximization model where levels of local public services are capitalized into property values. Using data for Wisconsin municipalities we demonstrate that service expenditure levels, and corresponding taxation levels, should be increased. In other words, the property value maximization test suggests that local public services in Wisconsin are consistently under-provided.

    This study summarizes an analysis of uniform, topographical and other site-specific soil fertility testing procedures based on observations of various crops at various locations in North Dakota and one location in Minnesota for 2001 through 2004. Results showed little difference in economic returns among the soil fertility testing methods by crop or location.
