68 INTEGRATED WATERSHED DEVELOPMENTAL PLANNING USING REMOTE SENSING & GIS Y.V.N. Krishna Murthy, A.K. Sinha, A. Jeyaram, S. Srinivasa Rao, S.N. Das, D.S. Pandit, D.S. Srinivasan, C.K. Rajender Regional Remote Sensing Service Centre, Nagpur 1.0 INTRODUCTION Integrated development is a comprehensive action programme aimed at optimal realization of resource potential in the light of physical, economical, social and other developmental goals. Such an endeavor entails harmonious development of land, water, vegetation and other resources of an area in a sustainable manner, so that the changes proposed to meet the needs of the development are brought about without diminishing the. potential for their future use. In order to derive maximum benefit out of these resources, in a sustainable way, it is preferable to treat the watershed as a single unit. Watershed is a natural geographical unit with a certain extent of homogeneity and uniformity. Even though the parameters vary, the variation shows a common trend. A watershed is an open physical system in terms of inputs of precipitation arid solar radiation and outputs of discharge, evaporation, transpiration and reradiation. It can be taken as a basic erosion landscape element where land and water resources interact in a perceptible manner. For all practical purposes it can be considered as a balanced system, whether it is water balance or energy balance. Thus, the watershed approach is holistic, linking upstream and downstream areas and the chain of cause and effect relationships is related by hydrologic processes. The utilitarian aspects of natural resources development within a watershed involving complex decisions are best handled by the state-of-the-art modern tools remote sensing and geographic information systems (GIS). Earth observing sensors on board aircraft and spacecraft and advanced image processing technology provide researchers, resource managers and policy makers with powerful tools for producing and analysing spatial, spectral and temporal information. Geographic information systems provide a tool for the effective and efficient storage and manipulation of remotely sensed data and other spatial and non-spatial data types for scientific, commercial, management and policy-oriented purposes. As such, remotely sensed data effectively employed within a GIS can be used to facilitate measurement, mapping, monitoring, modelling and management of natural resources. GIS not only facilitate the storage of and access to many types of data, but they also allow them to be updated readily. Indeed, the synergism between remotely sensed data for updating GIS information and the use of GIS for improving information extraction potential from remotely sensed data is a major advantage of integrating these powerful tools. 1.1 Approach A practical approach in planning, directed at preservation, conservation, development, management and exploitation of the natural resources of the watershed for the benefit of the people has to operate within the framework of : (i) Physical and biological attributes (ii) Socio-economic conditions and (iii) Institutional constraints Physical and biological attributes comprise baseline data on geomorphology, geology, soils, hydro geology, hydrology, climate, demography, plant, animal and other biological resources. Socio-economic conditions relate to information on basic needs of the people, input-output relationships, marketing and transportation arrangements, developmental incentives and facilities, such as technologies, equipments, labour, material, energy/power, etc. Institutional constraints relate to laws, regulations and ordinances; Governmental policies and priorities; political acceptability; accepted customs, beliefs and attitudes of the people, and administrative support. The separate inventories of the physical and biological attributes, socio-economic conditions and institutional constraints are integrated using GIS. This would provide the physico-socio-economic profile of the watershed and permit suitable development models in the different sectors of economy and production. The system as a whole, would thus be operated upon to develop appropriate alternatives of conservation- production programmes commensurate with the production potential. For example, a particular land unit-,
