GIS Based Integrated Land Use Planning For Optimum Natural Resource Management
Prof Ashish Kumar Samal,  Prof V Madhava Rao
Land is a natural resource and a pre-requisite for primary production system as well as for meeting social priorities such as shelter, communication, industrialization, infrastructure, agriculture, NRM and the like, however the scenario is changing due to soil erosion, salinisation, desertification, anthropogenic process, constructions, mining, industrialisation and other degradational processes, for which sustainable land development practices has become an urgent need. The land was looked as a physical entity in terms of its topography and spatial nature, now a renewed view with respect to atmosphere, climate, ground water, soil, terrain, hydrological, vegetative and land use taken predominance. In this context, a study was carried out to analyse the available land resource information and integrate them to generate action plans for land resource management, in Nalgonda distroict of Telengana State, India, with a primary aims of to evaluate the land resources, identify LULC and suggest a rational Action Plan, for optimizing the landuse without any adverse impact. The geological and geomorphological maps were prepared for providing alignment of transportation and communication routes and sites for irrigation, energy and industrial projects, delineating mineral and groundwater potential areas. Soil is a three dimensional continuum which depends on parent material, geomorphic processes, and environmental characteristics. Soil mapping showing soil erosion, excess salinity and alkalinity and water logging conditions prepared. Water resources mapping showing surface water and stream pattern, pre-flood and post-flood river configuration and flood plain mapping, water quality , irrigated areas, potential zones of ground water prepared. Crop identification and acreage estimation, crops growth, cropland, harvested fields, crop identification, prepared. Forest Maps showing extent of forest cover, type of forest tree species, vulnerable areas for forest fire, disease monitoring, excessive felling, clearing of forest for agriculture prepared. Based on all these layers, the land use planning is prepared for the future use of the land and the changing demands of the area and the communities. Suitable site specific recommendations for alternate land use and water conservation measures, for optimum land use keeping in view the requirements of present and future for the district of Nalgonda has been prepared to recommend the areas of human habitation, lands to be used for production of food, fiber, commercial and horticultural crops, areas having standing crops during July to September/October months, double-cropped areas, delineation of fallow land , which can be brought into productive use, forestry, scrub lands, waste lands, water bodies, ground water potential zones, broad soil types, slope, aspect, etc are prepared for developing the district. The present study helped in the reconnaissance survey of the area as well as integrating the information to look at different scenarios in the landscape and plan for sustainable use of the land, which give an insight into the areas potential for alternate land use, for natural resource management for sustainable development.
