Water Scarcity and Management in the Thar Desert
Water scarcity solutions in Thar desert are crucial for sustainable development in this arid region. The Thar Desert faces severe water shortages due to minimal annual rainfall, ranging from just 120-240mm, coupled with extremely high evaporation rates.
Water is a precious resource in the Thar, essential for various economic activities:
- Mining operations
- Agricultural practices
- Tourism industry
- Daily household needs (drinking, cleaning, bathing)
The scarcity of water significantly limits development across these sectors. In some areas, the situation is exacerbated by over-irrigation, leading to water logging and subsequent salt deposits that hinder crop growth.
Example: In Jaisalmer, known as the 'golden city' due to its sandstone architecture, water demand has increased dramatically. Over the past 15 years, human water consumption has multiplied twelvefold, straining local resources.
The lack of proper wastewater management poses additional challenges. In Jaisalmer, uncontrolled wastewater seepage is undermining the foundations of the historic fort, causing walls to crumble and posing safety risks.
Highlight: In 1998, a wall collapse at the Jaisalmer fort resulted in six fatalities, underscoring the urgent need for improved water management.
To address these challenges, various traditional and modern solutions are being employed:
- Utilizing natural depressions between sand dunes as small drainage basins
- Traditional water storage in Tobas (natural ponds)
- Water-saving practices like washing with sand and using buttermilk for cooking
- Construction of the Indira Gandhi Canal in 1958 to provide irrigation and drinking water
These measures aim to improve water availability and management, supporting sustainable development in the Thar Desert region.
