Much hope has been vested in pricing as a means of helping to regulate
and rationalize water management, notably in the irrigation sector. The
pricing of water has often been applied universally, using general and
ideological policies, and not considering regional environmental and
economic differences. Almost 15 years after the emphasis laid at the
Dublin and Rio conferences on treating water as an economic good, a
comprehensive review of how such policies have helped manage water
resources an irrigation use is necessary.
The case-studies presented here offer a reassessment of current policies
by evaluating their objectives and constraints and often demonstrating
their failure by not considering the regional context. They will
therefore contribute to avoiding costly and misplaced reforms and help
design water policies that are based on a deeper understanding of the
factors which eventually dictate their effectiveness.
