If you want to understand the use and usefulness of small reservoirs in developing countries, you need to know about water, landscape, people, agriculture, fisheries, politics etc. etc.
Working with my colleagues of the Small Reservoirs Project (funded by the Challenge Program for Water and Food of the CGIAR), I was often amazed about the audacity with which they really wanted to find out everything, EVERYTHING that there was to find out about these reservoirs.
And even more, they also wanted to help everyone else to use the tools they developed to understand everything from storage capacity to water politics. I have rarely seen a research project that was able to attract so many dedicated and enthusiastic researchers beyond the original core team and now they have put everything that they have found out about how to find out EVERYTHING (about small reservoirs) together in the Small Reservoirs Toolkit.
