Vast piece of fertile agricultural land remain fallow during major fraction of the year in most of the developing countries due to lack of technology and assessment. Nagaon, a district of Assam falls south of perennial-river Brahmaputra, making it the most fertile land due to alluvial and silt deposits. To demonstrate the agricultural fallow land study has been carried out by computing the cropping pattern of the district using spectral information in respect to crop phenology from Landsat OLI 8 for 3 consecutive crop year. Various crops in different seasons were identified through site investigation. The result of the pilot study uncovers major fraction of cultivable land is left fallow. Post Kharif crop Rabi area 54% (107593 ha), and post Kharif crop Zaid area 39% (77399 ha) are identified as a potential area for crop intensification. Finally, cropping system indices (namely, MCI, ADI and CLUI) was used to implement proper planning to increase total productivity and also to identify areas that needs crop intensification, crop diversification or both. Block-wise statistics were prepared for comprehensive development strategies for crop area expansion. This study can be extended to other states/ districts throughout the world as data collected by satellite can be standardized, the data are reliably objective.
