Résumé
Water is an important resource for socio-economic development in the Eastern Nile Basin. Current water withdrawals are at the limits of available renewable water resources. Competing demands on water use and allocation include population increase, climate change uncertainty, and the socio-economic and political situation prevailing in the region. Scrutiny of the water balance shows this resource is not a binding constraint for development and that perceived water problems are the result of naturally occurring uneven distribution and inadequacies related to water resources mismanagement. This research aims at finding paths to create flexibility in water availability for the basin. Focus is set on agriculture, the largest land- and water-demanding sector. Examining irrigation efficiency, agriculture practices, rainwater harvesting, and cropping patterns several strategies are proposed and assessed. Results show there is potential to increase the annual water availability up to 11 billion cubic meters, a value representing 13% of the Nile Waters Agreement flow. The largest impact stems from strategies that have little or nothing to do with infrastructure for or policy on water resources, at least from a traditional standpoint. This work aims at shifting the current conversation - in a region where riparian countries struggle to allocate water framing it as a limited resource - to exploratory and collaborative efforts towards sustainable solutions by reframing water as a flexible resource.
