By affecting evapotranspiration and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e., both attenuating floods and maintaining flow duri...

Rainfall variability is a key constraint to agricultural production and economic growth in many developing countries. This is likely to be exacerbated in many places as rainfall variability is amplified (even where the total amount of rain increases) as a result of climate change. Changes in rain...

The concept of ‘Underground Taming of Floods for Irrigation’ (UTFI) is introduced as an approach for co-managing floods and droughts at the river basin scale. UTFI involves strategic recharge of aquifers upstream during periods of high flow, thereby preventing local and downstream flooding, and s...

A review of global water demand projections (WDPs) show substantial overpredictions or under-predictions. The pre-1990 WDPs, with population as the main driver of change, overpredicted current water use by 20 to 130%. The post-1990 WDPs, with sophisticated modeling frameworks, show substantial un...

Although the protection of the aquatic environment is high on the world water resources agenda, most developing countries still lack the technical and institutional capacity to establish environmental water allocation practices and policies. The existing methods of assessment of environmental wat...

The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrologica...

Project report submitted to UNEP under the SADC project "Dam Synchronization and Flood Releases in the Zambezi River Basin".

Water infrastructure is a cornerstone of economic development. In the Zambezi River Basin huge investments have been made in dams for hydropower, irrigation, water supply and flood control. Ecosystem functions are central to outcomes from dams. Not only does the performance of dams depend on ecos...
