Change Detection using NDVI in Some Selected Villages of Pendurthi Mandal as an Aid to Augment Crop Production, Visakhapatnam District, Andhra Pradesh, India: A Geospatial Study

Abstract

With global warming and the overexploitation of resources driven by population growth and other challenges, several research projects are underway worldwide to restore balance between current resource use and consumption. In the Visakhapatnam district, Andhra Pradesh, India, in Pendurthi mandal, a few villages have been selected as exemplary models to promote sustainable green initiatives that boost crop production and provide adequate fodder for livestock using NDVI. NDVI of the study area was calculated in ArcGIS 10.0 using Sentinel 2015 and Sentinel 2025 data. Change detection is used to present the study's findings, which can aid in planning and construction of sustainable villages to boost vegetation in the study area. NDVI plays a crucial role in distinguishing healthy vegetation from areas lacking vitality, as it reflects the unique spectral characteristics of thriving plants. This technology enables effective monitoring of plant growth and health, including stressed or damaged areas. Its applications are vast, encompassing crop monitoring, vegetation health assessment, precision agriculture, land-use and land-cover mapping, and ecosystem health monitoring. The selected village communities are currently undergoing considerable human-driven changes. The details from this study can serve as a foundation for planning and developing sustainable village practices.
