Comparison of Rainfall Variability in the Kurnool Division of the Rayalaseema Region of Andhra Pradesh

Abstract

Water is essential for everyone. It comes from rain, as well as from streams and canals. Lakes, ponds, rivers, watersheds, oceans, and seas are all sources of water. Rainfall plays a significant role in Indian agriculture and is crucial for the nation. It impacts not only agriculture but also households, industries, and other businesses across the primary, secondary, and tertiary sectors. This underscores the importance of studying rainfall distribution and variability in drought-prone areas like the Rayalaseema region. Some rural and urban settlements are experiencing water shortages. The government is implementing sanitation schemes in both rural and urban areas. The research utilizes statistical methods, including a periodic analysis of annual rainfall differences. It examines the variability of district rainfall in the Kurnool division of the Rayalaseema region of Andhra Pradesh over a decade, from 2000 to 2021. The findings indicate important fluctuations in rainfall patterns, with implications for agricultural productivity and water management strategies in the region.
