Abstract The present investigation was carried out in Kupti watershed (11257 ha) of Darwha block, Yavatmal district, Maharashtra to characterize, map and evaluate the natural resources for their proper management and land use planning using remote sensing and GIS techniques. The soil data were collected at 1:10000 scale. The LANDSAT satellite data were interpreted in conjunction with SOI toposheet No. 55L/11 to derive spatial information about land use/land cover change, slope, physiography and ground water potential. Temporal data for the year 2000, 2005, 2012 and 2016 were analysed for land use land cover changes. Socio-economic data were collected through interview and informal interaction. Slope map of the study area was prepared by Cartosat-DEM 30m resolution that enabled to classify the study area into five slope classes viz. very gently sloping (4168 ha), gently sloping (2015 ha), moderately sloping (1646 ha), moderately steeply sloping (1824 ha) and steeply sloping (1605 ha). The study area revealed six major landform units viz., plateau top, pediment, upper alluvial plain, lower alluvial plain, escarpment and isolated hillock covering an area of 4749 ha, 4255 ha, 605 ha, 603 ha, 259 ha and 148 ha respectively. LULC studies showed a significant change. The ground realities of changes and impact of those changes were verified and ascertained respectively through field observations and site-specific interviews. During 2000 and 2005 period, the croplands decreased by 2.2 per cent in the watershed. The second notable decrement in these years was the wasteland area (709 ha in base year) that was constantly decreasing and is now 493 ha in 2016 as it was converted to croplands mainly due to encroachment by the farmers or by habitation (49 ha increased from 2000 to 2016). Further, 246 ha of area of waterbody was added in the watershed during 2000 to 2005. An increase in the forest cover was 8 ha over 2285 ha within 15 years. Soil survey at 1:10000 scale was carried out using base map and landform-soil relationship was established. Ten soil series have been tentatively identified. The representative of each soil series were analysed for different parameters. The soils of very gently sloping and gently sloping plateau top were shallow to slightly deep, well drained to somewhat excessively drained, clay loam to clay, moderate to severely eroded and classified as Lithic Ustorthent and Vertic Haplustept whereas, most soils occurring on very gently sloping lower and upper alluvial plains were deep, well drained, brown (7.5YR 3/2 and 10 YR 4/2) in colour, calcareous, clay loam to clay in texture, moderately eroded were classified as Vertic Haplustept and Typic Haplustert. The soils of pediment occurring on gently to moderately sloping lands were very shallow to moderately deep, clay in texture, moderately eroded were classified as Lithic Ustorthent and Typic Haplustert. The soils of escarpments on moderately steeply sloping lands were shallow, well drained, clay loam, very severely eroded and classified as Lithic Ustorthent. Surface horizons of most of the soils exhibit medium, moderate subangular blocky structure whereas, it is sub-angular to angular blocky in the sub-surface horizons. Ground water recharge potential assessment of Kupti watershed indicate that ‘High’ recharge potential zone (7.1% of TGA) is located around the drainage channels and waterbodies. ‘Poor’ recharge zone (26.3% of TGA) occurred in hilly region, forestland and wasteland. More than 50% of the watershed area was observed to have ‘Poor to Moderate’ potential. Wells density was higher (0.11 per ha) in ‘Moderate to High’ recharge potential area and lower in (0.01 per ha) in ‘Poor’ potential area. The recharge potential map could substantially help in decisions related to investment in direct recharge of abandoned open wells. Soils were evaluated for their land capability, irrigability, productivity and suitability classes for the crops grown in the area. The soils are grouped into IIIes, IVes, Ves, and VIes and 2st, 2t, 2std, 3s, 3std, 3t, and 4st land capability and irrigability subclasses, respectively and have poor, average and good productivity classes. The soil-site suitability evaluation of soils of Kupti watershed indicate that 649.1 ha i.e. 5.8 per cent of total geographical area is not suitable for all agricultural crops due severe limitation of depth and PAWC whereas, in moderately suitable class cotton (36.2%), soybean (45.6%), sorghum (45.3%), pigeonpea (17.5%), wheat (36.2%), chickpea (2.6%), green gram (47.9%) and black gram (47.9%) were found. Pigeonpea is highly suitable in 36.2% of watershed area. A Decision Support System was developed for land use planning of Kupti watershed that enables a cadastral level information. It will assist the farmers in taking guided decisions about the crop to be grown while administrators can visualize different scenarios originating from amount of rainfall received, its effects on ground water recharge, crop response and socioeconomic impact.
