IWMI Research Reports

The publications in this series cover a wide range of subjects — from computer modeling to experience with water user associations — and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some Research Reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.

Although most of the Research Reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each Research Report is reviewed internally by IWMI staff, and by external reviewers.
