Climate and Weather

For a long time now, historians have been using epigraphy to infer the political and economic aspects of the past.

Every year, thousands of villages in Maharashtra get affected by droughts. Experts say that the reasons for recurrent droughts include a lack of policy framework, technical knowledge and community participation as well as poor implementation of government programmes.

Water is a crucial part of all societies as it has myriad uses. In India, however, it is of much more importance as over 600 million people make a living off the land. They rely on the monsoon to replenish their water sources and the unpredictable nature of rain leaves them vulnerable. Even today, the country breaks out in a cold sweat every time the south-west monsoon is delayed.

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion.

River Mahakali snakes its way through the hills and valleys of Nepal and Uttaranchal, collecting its water from the numerous streams it receives on the way. Also known as Sharda in India, the river forms the international boundary between India and Nepal.

Understanding water in all its forms in every part of the water cycle is vital to ensuring its sustainable and equitable management. Whether there is a scarcity of water or an excess of it, knowing precisely the quantum of water, whether underground in aquifers, embedded in the soil as soil moisture or in numerous lakes, reservoirs and rivers is vital.

Alternative Futures: India Unshackled is a riveting new book that brings together scenarios of an India that is politically and socially egalitarian, radically democratic, economically sustainable and equitable, and socio-culturally diverse and harmonious.
