Title: Remote sensing and GIS for land use mapping and crop planning in Cauvery delta region of Tamil Nadu, India.
Abstract:Land use map of Cauvery delta zone was prepared using satellite data and it revealed that distributions of crop lands were classified into kharif + rabi (124927 ha, 54.3%), kharif crop (1069 ha, 0.46%...Land use map of Cauvery delta zone was prepared using satellite data and it revealed that distributions of crop lands were classified into kharif + rabi (124927 ha, 54.3%), kharif crop (1069 ha, 0.46%), rabi crop (17461 ha, 7.59%) and aquaculture (721 ha, 0.31%). within forest, marsh vegetation and deciduous forest area were 251 ha (0.11%) and 6782 ha (2.95%), respectively. The waste land was subdivided into waterlogged area, mud flat, marshy and swampy, sandy area, mining and industrial area. It was observed that kharif + rabi crops occupied more than 50% of the cropped area due to the favorable climatic parameters, moisture availability and fine texture of the soils. The results of cross tabulation of soil and land use units revealed that land use unit 1 of kharif + rabi double crop was distributed in an area of 54.3% of total geographical area. Land use units 1 was occupied more than 50% in the entire mapping unit except in soil unit 15 and 10. Based on the soil and water resource information and present land use system, a rice crop has to be cultivated in 70% of the area (161380 ha) and its cultivation, depends on the water availability in kharif and rabi seasons, farmers can choose double crop (kharif + rabi) or a single (rabi) crop. It was suggested to raise groundnut or coconut on 13.2% area not suitable for paddy. sugarcane, gingelly, brinjal, chillie crops were recommended in pre rainy season period in fine textural soils depending on the water availability. Pulses like blackgram and greengram were also suggested to cultivate in rice follow to better utilize the residual soil water in the profile and rainfall.Read More
