Why is water harvesting system a viable alternative?

Water harvesting system is considered a viable alternative because of the following reasons:

1. Socio-economic viability: Multi-purpose projects have several disadvantages, including the displacement of people and the destruction of their homes and livelihoods. Water harvesting system, on the other hand, can be implemented without disrupting people’s lives, and can even provide socio-economic benefits like increased agricultural productivity and income.

2. Environmental viability: Multi-purpose projects often have negative environmental impacts, including the destruction of habitats and the disruption of natural water flows. Water harvesting system, on the other hand, can work in harmony with the environment, preserving natural resources and habitats.

3. Traditional knowledge: In ancient India, people had in-depth knowledge of local rainfall regimes, soil types, and ecological conditions, and developed a wide range of techniques to harvest rainwater, groundwater, river water, and flood water. This traditional knowledge can be harnessed and adapted to modern water harvesting practices.

Overall, water harvesting system is a sustainable and effective way to manage water resources, providing socio-economic and environmental benefits while preserving traditional knowledge and practices.
