From the reviews: "CAs are voluntary agreements negotiated between farmers and water suppliers ... . This is a very empirical and concrete book, providing very useful documentation of the European experience with CAs since the 1990s. ... For those working on water and environment issues in other parts of the world, notably the developing world, this book provides interesting insight into how the process of the internalisation of environmental concerns into national, regional and local water policy and practice is happening in Europe."
