Introduction Disaster management has evolved from a centralized, top-down approach to a more inclusive and participatory model, where local communities play a central role. In a country like India—marked by vast diversity, high population density, and varying vulnerability—community participation becomes not just desirable but essential. Disasters often strike suddenly, and the first responders are not…
Introduction India, due to its vast geographical diversity and socio-economic conditions, is among the countries most vulnerable to climate change-induced disasters. In recent decades, the frequency, intensity, and unpredictability of disasters such as floods, cyclones, heatwaves, droughts, and landslides have increased significantly. Unlike traditional natural disasters, these events are increasingly being influenced or intensified by…
Introduction India’s geographical diversity—ranging from the Himalayan mountains to long coastlines and vast river systems—makes it highly prone to multiple types of disasters. Over time, it became clear that ad hoc relief-based approaches were insufficient to deal with the growing scale and complexity of disasters. This led to the creation of a dedicated institutional mechanism,…
Introduction Disasters, whether natural or man-made, have been an integral part of human history. However, in recent decades, their frequency and intensity have increased significantly due to factors such as climate change, rapid urbanization, environmental degradation, and population growth. These disasters not only cause loss of life and property but also disrupt socio-economic systems and…
Introduction Tropical cyclones are among the most destructive natural hazards, capable of causing massive loss of life, property damage, and economic disruption. Across the globe, these storms are known by different regional names such as hurricanes in the Atlantic and eastern Pacific, typhoons in the western Pacific, and cyclones in the Indian Ocean and South…
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 Coral reefs, often referred to as the “rainforests of the sea,” are among the most biologically diverse and productive ecosystems on Earth. They provide shelter, food, and breeding grounds for nearly one-quarter of all marine species, despite covering less than 1% of the ocean floor. Beyond biodiversity, coral ecosystems contribute to human societies by…
Introduction Landslides are among the most destructive forms of natural disasters that occur due to the downward and outward movement of slope-forming materials like rocks, debris, and soil under the influence of gravity. In India, landslides are a recurrent hazard, especially in the mountainous and hilly terrains that cover a significant portion of the country….
Introduction Biological disasters, particularly pandemics, have emerged as some of the most complex and devastating challenges for modern societies. India, with its vast population, diverse ecology, and varying levels of healthcare infrastructure, is particularly vulnerable. The COVID-19 pandemic exposed many gaps in India’s biological disaster preparedness, but it also catalyzed reforms. In this essay, we…
Introduction Earth’s climate system is a complex interaction of various atmospheric, oceanic, and terrestrial processes. Among the most influential natural climatic phenomena that disrupt this balance are El Niño and La Niña, collectively known as the El Niño-Southern Oscillation (ENSO). These irregular periodic variations in sea surface temperatures (SSTs) and wind patterns in the central…
