Environment and Development (UNCED) in Rio de

integrated approach to water management. Global

behind the internationalisation of the concept. GWP

resources management as sectoral polices have
proven to be ineffective. IWRM provides an interface
for policy integration which is challenging and has
been beset with both technical and conceptual
problems. But integration is a multidimensional
phenomenon including strategic, structural,
