A Geospatial Approach To Optimal Land Utilization And Farming Systems of A Sub-Basin of Raiwada Watershed, Visakhapatnam District, Andhra Pradesh, India

Abstract

In the ancient past, Indian civilization was highly prosperous. However, population pressure on the planet and frequently changing governmental plans have outdated traditional lifestyles and rural habits. Due to such changes, there was no option but to apply scientific and modern technology and the absolute necessity to pace with the changing times.

The natural resources in an area, including the most precious commodity that is water, have become scarcer due to (1) the depletion of the available resources due to misuse and abuse over time, (II) neglect of water works (tanks and canals) (III) the increased dependency in living on the government subsidies. Therefore, to mitigate the problem, an objective assessment of the available resources and a rational distribution of the same become imperative.

Therefore, remote sensing for optimum utilization of resources was attempted along with GIS techniques. Different thematic maps have been prepared and integrated into the Geographical Information System environment. The interpretation based on these maps was transformed into several recommendations whose implementation may lead to far-reaching changes in the development of the land's economy and people's well-being.
