A spatial analysis of cropping intensity and canal proximity in Janjgir-Champa district using Sentinel-2 Imagery (2022-23)

The main objective of the present study is to determine the spatial relationships between crop intensity and canal proximity in the Janjgir-Champa district using Sentinel-2 Satellite Imagery (2022-23). This research utilized spatial techniques such as NDVI, QGIS-based multi-ring buffer analysis (500-2500 meters), and zonal histograms. According to the results of the analysis, the district's crop intensity is 108.16%, with agricultural intensity highest in the Nawagarh and Janjgir tehsils. The buffer analysis indicates that crop intensity is highest within 500 to 1500 meters of the canal network, while it gradually declines beyond 2000 meters. Comparing the Satellite-based data with district statistical data yielded an RMSE of 7.38 for cropping intensity index and 4799.73 hectares for the irrigated area, which is a testament to the high accuracy and scientific rigor of the study. In conclusion, this study certifies that the canal irrigation facility plays a key role in increasing crop intensity and provides a scientific basis for agricultural planning at a micro-level in the future.
