During the last decade, a large number of developing countries have engaged
into irrigation policy reforms. Such reforms are frequently associated wit
h changes in the distribution of irrigation benefits among interest groups.
This paper investigates the nature of the existing economic rent in public
irrigation systems. It proposes a conceptual framework to analyze its dist
ribution between private and public actors involved in irrigation managemen
t. A case study is conducted in Pakistan's Indus basin to quantify the over
all level of rent granted to the irrigation sector and to show how farmers
compete for the appropriation of the greatest possible share of this rent.
