OAR@ICRISATMonitoring Rice Cropping Pattern and Fallows in Central and Western Part of IndiaPVineethaauthorIndia has the largest area under rice cultivation and holds the second position all over the world as it is one of the principal food crops. Rice-fallow croplands areas are those areas where rice is grown during the Kharif growing season (June- October) followed by fallow during Rabi season (November-February). These croplands are not suitable to grow in Rabi season rice due to their high water needs, but are suitable for short season (≤ 3months). According to national statistics there is an increase in the rice areas in Central and Western states of India. The goal of this project is to monitor the rice-fallow cropland areas & mapping the expansion of rice areas. This study is conducted in Central and Western states of India where different rice eco-systems exist. Time series Moderate Resolution Imaging Spectroradiometer (MODIS) 16days Normalized Difference Vegetation Index (NDVI) at 250m spatial resolution and season wise intensive ground survey data was used. We have applied hierarchical classification and Spectral Matching Techniques (SMT) to map rice areas and the fallows there after (rabi-fallows), in Central and Western states of India. And change detection was carried during 2000-2015 and 2010-2015. The resultant rice maps are compared with available national and sub-national level statistics.GIS Techniques/Remote SensingRice2019-12Institute Of Science And Technology, Jawaharlal Nehru Technological University, Hyderabad;Centre for Spatial Information TechnologyThesis
