“…Afterward, the image of 2023 was geocoded with the help of GCPs collected from the field, and the other images were successively geo-referenced using the image-to-image georeferencing method. For the georeferencing of the successive images, a third-order polynomial geometrical model was selected and the root mean square error (RMSE) was retained less than 0.5 pixels (Bhattacharjee et al, 2022). The area of interest indicating the study area was clipped from the images using the same software.…”

The spatio-temporal growth trajectory of coastal brackishwater aquaculture (CBA) in the coastal tracts of Purba Medinipur, India and its impending repercussions on the immediate environs, was primarily assessed in this study through application of geostatistics, landscape metrics, and geospatial technologies. Three Community Development (CD) Blocks, namely, Contai-I, Deshapran, and Ramnagar-II were considered to analyze the growth pattern of the area under CBA. Landsat datasets of the assessment years (1991, 2001, 2011, 2021, and 2023) were used to prepare the land use/ land cover (LULC) maps and to derive pertinent landscape metrics of patch and class levels for this region. This brought forward a highly fragmented and dispersive spatial concentration of the CBA farms in the entire study area. Additionally, Census Village-wise growth pattern of CBA was analyzed by conducting a spatial autocorrelation analysis which depicted prominent clustering of villages with a higher concentration of CBA. Results showed that there has been an incessant growth of CBA in the last three decades, however, a sharp drop has been recorded owing to recurrent bouts of diseases, swelling production costs, and a sharp drop-in market rate. The nature of growth and/ or decay of the CBA was predicted for the year 2025 using Cellular Automata and Artificial Neural Network (CA-ANN) model. After careful calibration and validation, the model projected further lessening of the CBA area along with a continued expansion of abandoned aquaculture. Accordingly, ecologically viable livelihood alternatives and environmentally sustainable management measures were suggested for the efficient monitoring of these highly fragile tropical ecosystems.

This study, conducted in fire‐prone dry deciduous forests of Ajodhya and Susunia hills, aims to assess the diverse impacts of forest fire events on vegetation health, soil nutrient balance, and availability of nontimber forest products (NTFPs) that conjointly modulate the livelihoods of local communities. Vegetation health and soil nutrient pool were assessed through transect sampling at both fire‐affected (FA) and fire‐unaffected (FU) forest plots of the study area. Two depths (D1: 0–15 cm, D2: 15–30 cm) were considered for soil sampling. Vegetation parameters like basal area, canopy cover, above‐ground biomass, species diversity, and tree density were significantly lower (p < 0.01) in FA compared to FU. Organic C and available N were significantly lower (p < 0.01) at D1 of soils in FA than in FU. Significant differences were found in organic C (p < 0.01), available N (p < 0.001), and available P (p < 0.01) contents of FA and FU plots at D2. Participatory appraisals conducted among the neighboring forest‐dependent communities indicated that almost every forest fire event was human‐induced. These adversely affected extraction of Shorea robusta leaves, fuelwood, wild mushrooms, Madhuca indica fruits, etc. Conversely, Diospyros melanoxylon leaf production increased after 2–3 weeks of fire due to clearing up of hitherto untapped forestlands. Cumulatively, this study uniquely attempts to contextualize the environmental impacts of fire with its socio‐economic ramifications as evident from degrading natural resources, scarcity of essential NTFPs, and escalation in number plus intensity of human–animal conflicts.
