Exploring the Interactive Effects of Wells in Hardrock Areas of Peninsular India: An Illustration of the PRA Approach
The interactive effects of wells refers to the withdrawal of groundwater from one well resulting in a reduction in water level in another, accidentally connected, well. Among several wells the cumulative interference may be complex. Well interference poses serious threats to sustainability and equity in well irrigation. This paper provides a combination of statistical and PRA approaches for selecting farmers to study and analyse the equity issues involved. The statistical approach provides the method for sampling study sites, and PRA is used for selecting farmers in the study sites.
