Two such towering personalities are Sir Mokshagundam Visvesvaraya and Dr. Monkombu Sambasivan Swaminathan, whose groundbreaking work in water engineering and agricultural science respectively laid the foundations for India’s development…
Introduction Rivers are dynamic landform creators, and their lower courses often deposit sediments to form deltas at their mouths. Deltas are fan-shaped or triangular deposits of alluvium, formed where rivers enter a standing body of water such as a sea or a lake. India, with its vast river systems, hosts many prominent deltas, including the…
Introduction Sugarcane cultivation and sugar production have long been integral to India’s agricultural and industrial landscape. India is the second-largest producer of sugar globally, contributing significantly to rural employment, agro-industrial development, and foreign exchange earnings through sugar exports. Traditionally, northern states like Uttar Pradesh and Bihar have dominated sugar production due to favorable agro-climatic conditions…
The effective management of land and water resources plays a central role in alleviating poverty, reducing disasters, improving food security, and ensuring environmental sustainability.

Introduction The monsoon climate is one of the most distinctive climatic systems in the world, marked by seasonal reversal of winds, distinct wet and dry periods, and high rainfall intensity. It plays a crucial role in sustaining the agriculture, economy, and livelihoods of over 50% of the world’s population residing in Monsoon Asia, which includes…
Introduction Mountain ecosystems are among the most fragile and biodiverse ecosystems on Earth. They provide essential ecosystem services such as water regulation, biodiversity conservation, soil stabilization, climate regulation, and cultural heritage. These ecosystems support millions of people directly and indirectly through agriculture, forest products, and tourism. However, in recent decades, development initiatives and tourism have…
Introduction Water is one of the most essential natural resources, critical for human survival, agriculture, industry, and ecosystem sustainability. India, with a population exceeding 1.4 billion, faces a growing challenge of water stress, characterized by the scarcity of water relative to demand.
