Hydropower Along the Nile

Description: The following visuals highlight and help to better understand the hydropower expansion along the Nile River. The main factors explaining such development in the sector are: 1) Riparian countries lack access to grid electricity although demand is increasing with rising economies and population; 2) High hydropower potential with few existing infrastructure; 3) The Nile Basin Initiative (NBI) contributes to hydropower expansion by providing a forum for joint planning and cooperative development; 4) Availability of new funding sources from emerging powers (e.g. China, Turkey or Arab States).

Discussion - Co-evolutions Between Mega-Cities’ Development and the Vulnerability to Floods: Lessons from the Yangtze and the Yellow River

Description: Diversity in the type of impact - Each factor interacts on its own way with the variables of intensity of flood impact - There is no correlation between the variables of intensity of impacts. Public policies have to be put in their context - Take into account the geographic and socio-economic territories. Three characteristics to compare megacities worldwide

Challenge Map - Co-evolutions Between Mega-Cities’ Development and the Vulnerability to Floods: Lessons from the Yangtze and the Yellow River

Description: Watersheds are socio-ecological systems: human-beings and the environment interact (co-evolution), thus, natural disasters and urbanisation co-evolve. Observations: population distribution disparities - widespread high density areas - downstream dams for protection, and upstream dams for hydropower. How are people affected by floods? Evaluation of megacities’ vulnerability to floods, variations on the profile of risk is observed on: - number of floods - type of impacts (deaths, affected, damages), what are linkages between megacities’ structural characteristics and their vulnerability to floods?

Context Map - Co-evolutions Between Mega-Cities’ Development and the Vulnerability to Floods: Lessons from the Yangtze and the Yellow River

Description: Territories stressed by floods, more and more urbanized world, insights from China and two watersheds (among the world’s biggest), a multitude of megacities and dams are observed (used for protection or electricity generation)
