Land-use change in urban Bangalore using GIS and remote sensing

Priya NARAYANAN, Ashok HANJAGI

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 et.al., 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.

Certain aspects regarding the genesis, evolution and urbanization premises of Chisinau municipality

Elena SOCHIRCĂ

Abstract: Concrete knowledge about the genesis of a settlement has a great theoretical and practical importance, especially in a systematic process of territorial towns and villages. To know the genesis of settlements does not mean a simple historical “dating” or schematic reconstitution of a landscape. Such an approach, the genetic one, primarily involves knowledge about the capital feature of a nation, and its ability to develop into a stage or another, conditions that generate a way of life or another. Genesis of a settlement requires a good selection of socio-economic and natural factors ensuring the viability of any settlements, whether rural or urban, older or newer. Progress and current situation of the municipality of Chisinau is the result of complex socio-economic and natural factors, whose role and weight was changed over time and space according to the historical-political conditions. The evolution of the territorial Chisinau city is the result of the development of the functional settlement, in time and space, the gradual emergence of functions and development of existing and interconditioning of these with the demographic factor.
