Resumo(s)
The years fly by but the African continet and its enourmos richness remains an undiscovered
treasure. The Angolan province Cuando-Cubango includes one of the biggest watersheds of
the African continent, the Cubango-Okavango river basin. One of the rivers where most parts
remains untouched and in a pristine form. Ongoing water resources planning intends to
regulate large parts of the basin and to intensify human uses. In order to better understand
and to analize ecological responses of the Angolan part of this river basin, three main steps
were conducted: The first one was to develop and to validate a geomorphological zonation in
order to understand the evolution and the main characteristics of river planforms. In second
place, the different fish species that inhabit the main water courses where taken into account
and a fish zonation was designed for the entire watershed in order to establish biological
responses based on the species’s needs and their connectivity dependence. The projected
dams’ construction for the different rivers was analized and their impacts on the species
movements and habitat exploitation were desmasked in order to understand the ecological
implications of this constructions for the watershed enviroment.
