Introduction The Himalayas, often referred to as the “Third Pole”, host the largest concentration of glaciers outside the polar regions. They are the lifeline of several major rivers in South Asia, including the Ganga, Indus, Brahmaputra, and their tributaries, which support over 1.5 billion people. In recent decades, these glaciers have been shrinking at an…
The effective management of land and water resources plays a central role in alleviating poverty, reducing disasters, improving food security, and ensuring environmental sustainability. It is widely recognized that a mismanagement of these resources is at the core of many human miseries ranging from drought and famine to displacement, economic instability, and conflict. A systematic…
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 Mangroves are one of the most vital ecosystems in the tropical and subtropical coastal zones. They consist of salt-tolerant plant species such as Rhizophora, Avicennia, Sonneratia, and Bruguiera, thriving in intertidal regions where rivers meet the sea. Despite covering less than 1% of tropical forests globally, mangroves provide disproportionate ecological, economic, and social benefits….
Introduction In the 21st century, humanity faces the dual challenge of ensuring economic growth while safeguarding the environment. Rapid industrialization, urbanization, population growth, and technological expansion have created unprecedented opportunities but also generated critical environmental challenges. Climate change, biodiversity loss, deforestation, air and water pollution, and resource depletion threaten the very foundation of life on…
Introduction Agroecology has emerged as a transformative approach to agriculture that merges ecological science with traditional agricultural knowledge and sustainable farming practices. Rooted in both scientific and indigenous understandings of nature, agroecology seeks to design resilient farming systems that are ecologically sound, socially just, and economically viable. Central to the practice and philosophy of agroecology…
Introduction Climate change has emerged as a significant threat to global food security, ecosystem balance, and rural livelihoods, particularly in countries like India where agriculture remains the mainstay of millions. Erratic rainfall patterns, increasing temperatures, soil degradation, and the loss of biodiversity are intensifying farming challenges. In this context, agroforestry has gained prominence as a…
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…
Introduction In recent decades, the frequency and intensity of natural disasters have escalated dramatically across the globe. These disasters—ranging from cyclones, floods, earthquakes, wildfires, and droughts—are increasingly linked to the growing impacts of climate change. Rising global temperatures, melting glaciers, erratic rainfall, and rising sea levels are not only environmental challenges but also catalysts for…
Introduction The Himalayas, often referred to as the “Third Pole,” are home to the largest concentration of glaciers outside the polar regions. These glaciers are vital for sustaining perennial rivers such as the Ganga, Yamuna, Indus, and Brahmaputra. However, in recent decades, the Himalayan glaciers have been retreating at an alarming rate, threatening not only…
