Question

In which state pynes system of irrigation is common?

Answer 1

This paper published in the Indian Journal of Traditional Knowledge provides a brief overview of the the Ahar-Pyne system, a traditional water harvesting system still practised in the south Bihar plains of India and argues that these traditional water harvesting systems that have existed in India since a very long time are relevant or perhaps even more relevant in today's times and that there is an urgent need to revive these systems taking into consideration India's vulnerability to climatic changes and disasters and the increasing need for having sustainable water management systems in the future.
The article goes on to describe the details of the Ahar-Pyne system and its evolution, an overview of the physical features of the state of Bihar and the current status of the system. The reasons for the success of the system in the past have been attributed to the following factors:

Fragmented land holdings and equity in water distribution
Cheap source of irrigation
Uniformity in cropping
Collective action.
