Sustainable Water Storage for Food and Energy production (co-organized) 
Convener: Mário J Franca  | Co-conveners: Juan Carlos Chacon-Hurtado , John Conallin , Gretchen Gettel , Germán Santos 
Superficial water storage is essential to sustain and stabilize water supply, food and energy production, reduce hydro-climatological hazards, and adapt to climate change. Synergistic approaches to respond to both food and energy needs and an integrated management of water are essential to respond to the WEF Nexus, in particular to attain the Sustainable Development Goals 2, 6 and 7. In that sense, dams and reservoirs play a major role in socio-economic development and presently we witness a renewed interest in constructing new dams and reservoirs, mainly in Asia, Africa, and Latin America, while changes in operation and construction practices are almost inexistent. Conventional practices related to the construction and operation of dams and reservoirs, lead in the past to undesired social and environmental impacts. Most of these undesired effects are related or consequence of changes induced in the geophysical substratum such as water retention and redistribution in time, sediment upstream accumulation and downstream privation, and river morphology alteration. There is a risk that many of the previously experienced impacts may be repeated, perhaps more severely, alongside with unforeseen consequences. In response to this global development challenge, we propose a session to bring together the community of engineers, scholars and scientists, with a common interest on assessing the impact of artificial storage of water and the mitigation of its undesirable effects. To this end, we urge a thorough analysis and debate of the approaches to sustainable multipurpose water storage, including the definition and implementation of environmental flows, sediment management, geomorphology and landscape protection, ecological continuity and connectivity, socio-economic adaptation, among others. We intend to discuss improved approaches for sustainable multipurpose water storage, which not only considers the effects in the geophysical system (water, sediment, landscape) but also further implications related to socio-economic and ecological spheres.
