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.

We find that widows are about 13 percent more likely to experience pending land conflicts when their parcels are registered under the names of their deceased husbands than when titles are registered under their names.
