A look at new and existing hydropower projects on the Zambezi under climatic uncertainty
نویسندگان
چکیده
While holding great development opportunities to be seized, Africa has been identified as particularly vulnerable to climate changes, and the ZRB is no exception to that. With increasing demands to the Zambezi system in terms or water and energy, and rising challenges in the form of less runoff due to climate change, it is paramount to plan ahead. In particular, it must be understood how major hydropower schemes will interact with large and ecologically invaluable wetlands in order to support balanced decisions for the future of the basin.

Analysis of Future Hydropower Development and Operational Scenarios on the Zambezi River Basin
The Zambezi River basin is the fourth largest in Africa. Covering an area of about 1 400 000 km2 that is shared among 8 countries, it is the home of over 30 million people. There are ample opportunities for development in the region, including on the hydropower sector, whose estimated potential still to be exploited amounts to over 8 000 MW. In the future, the Zambezi is thought to be particula...
متن کاملHydropower Production in Future Climate Scenarios; the Case for the Zambezi River
Climate change remains a threat to water resources projects in southern Africa where impacts resulting from changes in climate are projected to be negative and worse than in most other regions of the world. This work presents an assessment of the impacts of climate change on water resources and hydropower production potential in the Zambezi River Basin. Future climate scenarios projected throug...
متن کاملA New Version of Earned Value Analysis for Mega Projects Under Interval-valued Fuzzy Environment
The earned value technique is a crucial and important technique in analysis and control the performance and progress of mega projects by integrating three elements of them, i.e., time, cost and scope. This paper proposes a new version of earned value analysis (EVA) to handle uncertainty in mega projects under interval-valued fuzzy (IVF)-environment. Considering that uncertainty is very common i...

متن کاملA New Uncertain Modeling of Production Project Time and Cost Based on Atanassov Fuzzy Sets
Uncertainty plays a major role in any project evaluation and management process. One of the trickiest parts of any production project work is its cost and time forecasting. Since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the ...
