Assessment of Climate Change Impacts in Andhra Pradesh Using Spatio-Temporal Ndvi Analysis and Geo-Informatics
Keywords:
Afforestation, Deforestation, NDVIAbstract
A comprehensive spatial analysis of the Normalized Difference Vegetation Index (NDVI) in Andhra Pradesh, focusing on the years 2011 and 2021 to assess changes in vegetation cover over the decade. This analysis intends to understand vegetation dynamics as well as their effects on ecosystem health and land management. We collected data using satellite imagery and NDVI calculations, yielding a quantitative assessment of vegetation cover across categories are sparse, very low, moderate and dense. The method used change detection to identify shifts in vegetation classes and evaluate trends in afforestation and deforestation.
The findings show considerable changes in vegetation cover between 2011 and 2021. Sparse vegetation increased from 40.66 to 44.44% while very low vegetation decreased from 33.71 to 20.91%. Moderate vegetation rose notably from 24.46 to 32.14% and dense vegetation, although minimal, increased from 1.18 to 2.52%. Change detection analysis indicated that 21.74% of the area remained as sparse vegetation, with 12.57% transitioning from sparse to moderate vegetation, indicating localized improvements. However, significant areas of dense vegetation shifted to lower classes, indicating environmental stress. Afforestation efforts accounted for 12.68% of land while deforestation impacted 15.59% causing concerns about ecosystem equilibrium.
In conclusion, the study illustrates a refined connection between vegetation recovery and continuing difficulties related to land degradation and climate change in Andhra Pradesh. The results underline the necessity for strategic land management and conservation initiatives to preserve environmental stability and promote sustainable growth in the region.
