🔆Micro-Water Shed Management and Development:

✅It’s one of the most efficient method of conserving water and managing scarce Water resources with a decentralized approach. Size of Micro watershed ranges from 100 to 1000 Hect. So, it gives scope for adopting area specific approach for better water resource management.

▪️What’s watershed?

✅Watershed is defined as any surface area from which rainfall is collected and drains through a common point.
✅“A watershed is a drainage area on earth’s surface from which runoff resulting from Precipitation flows past a single point into a larger stream viz., a river, a lake or an ocean”.
✅A watershed could be described as fan shaped (near circular) or fen shaped (elongated). Hydrologically the shape of the watershed is important because it controls the time taken for the runoff to concentrate at the outlet.
✅ Watershed management is the integration of technologies within the natural boundaries of a drainage area for optimum development of land, water, and plant resources to meet the basic needs of the people and animals in a sustained manner.

✅Watershed sizes are classified into three: micro, mini, and macro watersheds.

▪️TYPES OF WATERSHEDS

Watersheds is classified depending upon the size, drainage, shape and land use pattern.
✅Macro watershed (> 50,000 Hect)
✅Sub-watershed (10,000 to 50,000 Hect)
✅ Milli-watershed (1000 to10000 Hect)
✅ Micro watershed (100 to 1000 Hect)
✅ Mini watershed (1-100 Hect)

Amongst the above watersheds, Micro-Watershed is of utmost importance to develop successful strategy of water resource management.

✅Micro watershed
The smallest one: covers 100-1000 ha. It covers regional planning at the village level with the objective to improve the efficiency of water use for the betterment of agricultural productivity and the value addition of rural populations (SWAJAL Scheme)
