This document discusses hydrogeology and watershed planning from the perspective of an organization called Samaj Pragati Sahayog based in Madhya Pradesh, India. It explains how the organization started working on watershed projects and learned that considering groundwater systems is important for success. The document outlines developing typologies of groundwater systems based on geological features and using these to determine appropriate community-based management strategies. It provides examples of management protocols for different hydrogeology types and argues national policy should focus on mapping aquifers, pilots in different areas, demand regulation, community management, and empowering local institutions.
