To address the issue of equity in peasant irrigation, it is clearly insufficient just to analyze the distribution of irrigation water resources alone. We must also examine the distribution of other rights related to irrigation practice, as well as the distribution of obligations involving peasant irrigation. Further, it is also necessary to broaden the analytical focus since there are generally other users who require the same water, but for other, non-agricultural uses. And it is necessary, moreover, not to limit the approach solely to the level of the irrigation system, since part of the causes of injustice and various potential means for change toward a more equitable situation are often lodged within the system's interaction with external actors and related to the system's position within overall social structures. Therefore, any analysis must be multidisciplinary, the book's authors come from a wide range of disciplines and fields of work. The book is divided into an introductory section, eight parts with conceptual and empirical contributions, and finally some reflections. Of these eight basic parts in the book, the last four parts of the book focus on the book's central case, which is peasant irrigation in the Andes region.
