In irrigation systems over-abstraction of water and/or neglected maintenance are common problems
faced by their users. For a generalized system with head- and tail-users, which interact through water
abstraction and maintenance, a feedback structure is presented. It builds on causal relationships derived
from theoretical work on collective action and irrigation. The concept of the model can be looked upon as
a general formulation of two mutually but asymmetrically dependent groups of users with regard to a
common resource. Main objective of the study is to provide a systems framework allowing for a deeper
understanding of the social and institutional nature of irrigation problems. It is embedded in
transdisciplinary research in Kyrgyzstan and Kenya aimed at developing strategies for a sustainable future
in semi-arid rural areas.
