in conjunction with water could be profitably and sustainably exploited for agriculture or forestry or other uses, consistent with land capability evaluation so as to maintain ecological balance, provide protection against soil loss and land degradation and deliver clean and controlled tlow of water. Likewise, based on hydrologic groupings of soils, appropriate water management programmes would be identified not only to improve water regime and water use, but also to protect the land against water logging and salinization. 1.2 Prelude to Inventory Each watershed has its own problems, potentials and development needs, defined by a set of geo physical, climatic, demographic and socio-economic factors. It is necessary to have a broad idea about these aspects prior to information generation, primary for identifying the planning goals and deciding the abstraction level of thematic mapping in each case. The preparatory information is derived mainly from literature, including the State and Central Government Departmental reports and maps, as well as discussions with the Divisional, District and Block authorities and rapid traverses in the area. The information relates to : Specific needs of the people - Overall potential of the area - General problems of the area Availability of information - Gaps in the information Acceptability of the information 1.3 Planning Goals Based on the preparatory information, the following broad planning goals are addressed. • Provide for basic needs of the people - water, fuel, food and fodder. • Develop and optimize primary production systems and practices - Agriculture, forests, grasslands, fruit and other economic plantations. • Control of soil erosion/land degradation and reclamation of degraded lands. • Soil conservation, sediment control and runoff moderation. • Optimize production of minerals with proper plans for rehabilitation of mined areas. • Restore wastelands to their production potentials consistent with land capability classification. • Development and management of surface and ground water resources. • Optimize irrigation and management of agricultural land. • Promote animal husbandry, dairy development and poultry. • Industrial growth, environmental security and improvement of socio-economic conditions. 2.0 DATA BASES The data bases are meant to serve an efficient system of information gathering, compiling, classifi cation, transformation, storage, retrieval synthesis/ analysis and presentation. Data base comprises of spatial information which are derived from remote sensing satellite data and available maps as well as non spatial information collected from different sources. 2.1 Remote Sensing and Collateral Data (a) Remote Sensing Data IRS L1SS-II, LISS-III and PAN data are exten sively used for generating spatial data bases. Multi date satellite data covering the whole watershed are considered necessary to guard against any information loss and improve data sensitivity. (b) Collateral Data The collateral data available with various agencies are collected and attribute database has been established. - Topographical maps - Detailed soil survey maps and reports - Vegetation map and reports - Ground water map and reports - Geological map and reports - Socio-economic data - Existing water and soil conservation practices - Existing developmental schemes. 2.2 Base Map Digital Cartographic Data Base (DCDB) with the planning unit of a village and corresponding sub watershed linkages is prepared by digitising the watershed boundary and other cultural features from topographical maps. Masks of watershed, taluks, forests and cultural features are generated. The district and tahsil masks are used to extract data pertaining to these administrative units from the classified image and hence are useful in areal statistics generation.
