Abstract: Environmental changes, modifications in ecosystem structures and the loss of biodiversity affect the whole planet and have aroused worldwide public concern. Since the beginning of the 20th century, scientific and political debate on these issues, both nationally and internationally stated (Boletta et. Al. 2000) have pointed towards land-use change, which is one of the most important human and nature induced environmental changes. Generally, land-use change refers to the alteration in the physical land surface and biotic component on it. Monitoring land-use change has become an important theme of research. Land-use has enormous effects through fragmentation of natural habits (Tuner, 2003; Verburg at. Al 1999; Vitousek, 1994). Bangalore is internationally recognized as a technological hub. Along the proud economical growth of this knowledge capital of India, there are noticeable blemishes in terms of its loss of ecology and threatened food security. Such changes can clearly be attributed to land-use change. When compared with its past status, the present land-use of the city clearly denotes the mounting pressure of some classes of land-use which are under stress. A balanced and sustainable growth is often only conceptual in terms of urban land-use. Using GIS and Remote Sensing, this case study for Bangalore clearly marks the awaiting problems that are caused by land-use changes. The resultant statistics also gives the scope for the future planning of land-use.
