Watershed land and hydrology are resources that are very important in agricultural development. Adequate and proper land use planning and management of these resources is of ultimate importance in sustainable development. In this study remote sensing and Geographic Information System (GIS) techniques were used to generate information on the current status and utilization potentials of the Kubili watershed and generate local specific micro watershed development plans for the area. The study revealed that about 33.25 per cent of the land cover is used for rain fed agriculture that lacks sufficient soil and moisture to support good yield. The drainage density …

This study investigates whether a fuzzy clustering method is of any practical value in delineating urban housing submarkets relative to clustering methods based on classic (or crisp) set theory. A fuzzy c-means algorithm is applied to obtain fuzzy set membership degree of census tracts to housing submarkets defined within a metropolitan area. Issues of choosing algorithm parameters are discussed on the basis of applying fuzzy clustering to 85 metropolitan areas in the U.S. The comparison between results of fuzzy clustering and those of crisp set counterpart shows that fuzzy clustering yields statistically more desirable clusters.
