The objective of this study was to analyse the impact of hydropower operation on surface
hydrology dynamics of the Zambezi river basin, and understanding how such dynamics could be
affected by future climate change. This study entailed the synthesis of existing GIS and
monitoring data, hydrological data analysis, development of a model application of the Reservoir
System Simulator (ResSim) for the Zambezi; verification of the model for historical conditions,
and evaluation of the effect of future climate change scenarios on reservoir water levels, river

The Zambezi as a shared water resource in SADC presented numerous sensitive issues related to data availability and data sharing. The data needed included climate, flow, agricultural water use, groundwater hydrology and use, water quality and all the flow information. The Zambezi is also used for power generation and this impact on flow.
The information base also included remotely sensed information, soils maps, landuse and the geomorphology of the total Zambezi catchment.
The project also looked at access to existing models and their applicability as management models, with the man aim to also be usable in terms of dam level responses related to power generation.
Three groups were found that developed models for the Zambezi Catchment. The first was a group at TU Delft, the second a group from Switzerland, and the last, a group from South Africa.. The first two used SWAT modelling and the last used the South African Pitman model, also known as SPATSIM. SPATSIM was made available to group and the group was trained to use SPATSIM
The SPATSIM (and Pitman) model is used by the South African water authorities as a water planning model. The model is based on flow measurements and response curves and mainly driven by distributed rainfall data.
SPATSIM was found to be a good model to use for the Zambezi Catchment and ultimate aim is to include SPATSIM in the ZAMCOM database system to be utilized for future water planning. This model was also easier to set up, making use of CRU climate data and all the flow data for the catchment.

The Zambezi River is a very important water resources with its catchment area covering most parts of Southern Africa. It is a habitat to a wide range of plant and animal species. Humanity in this region just like other animals depend on water from the Zambezi River and its tributaries. Its dependence ranges from provision of potable water, agriculture, power, manufacturing, mining, tourism and many other sectors (World Bank 2010). With such benefits from the river, the human population is proved to be rapidly increasing.

Le monde affronte, depuis le début de l’année, une crise sanitaire sévère provoquée par un virus nouveau, le SRAS Cov 2, aussi appelé Coronavirus ou Covid-19. À juste titre, 1,3 milliard d’Africains s’inquiètent de cette crise née en Asie, devenue rapidement européenne puis américaine, et qui est en train de devenir africaine. Trois questions taraudent les esprits, de Casablanca à Abidjan et de Dakar à Libreville : le continent parviendra-t-il à rester à l’écart de cette pandémie et quelles conséquences cela aura-t-il sur la vie quotidienne ? combien de morts au bout du tunnel ?

REMARKS AT ONE PLANET SUMMIT Paris, 12 December 2017
[as delivered]
President Macron, Excellencies, World Bank President Jim Kim, Ladies and gentlemen,
We are not yet winning the war on climate change — the defining challenge of our times.
The Paris Agreement lays the basis for ambitious action.
But we know that current commitments will not get us there.
Every day, in every region, the front pages are dominated by weather-related disasters – storms, floods, droughts, fires.

Document published in 2011 by OSS (Sahel and Sahara Observatory), focused on the design and implementation of a hydrogeological model of the Iullemeden Aquifer System. The aquifer, extending through Mali, Niger and Nigeria, is one of the two outmost important groundwater systems in the Niger basin, with groundwater flowing mainly from north to the south.
