IWRA WEBINAR Sustainability of Engineered Rivers in Arid Lands: Challenge and Response 23 September, 15h Central European Time
IWRA’s next webinar will introduce participants to major river systems that typically originate in
mountains and flow through arid or semi-arid climates downstream. For millennia, spring floods have
deposited fertile soil here, which together with diversions from the rivers’ flows have enabled extensive
irrigated agriculture. These downstream areas form the backbone of regional economies and world
food production. Engineering works in these river systems, notably reservoirs built over the last 120
years, have increased year-round water supply for food production and for growing cities. Yet today,
climate change, reservoir sedimentation, depletion of groundwater and reduced environmental flows
challenge the sustainability of these river systems. This webinar addresses the above concerns and looks
at possible responses.
The theme of this webinar was that of a multiyear project, Sustainability of Engineered Rivers in Arid
Lands (SERIDAS), introduced in Water International by Aysegül Kibaroglu, Jurgen Schmandt and George
Ward in the article entitled “Engineered Rivers in Arid Lands: Searching for Sustainability in Theory and
Practice” (42.3, 241-253). The full results of the project will appear shortly in a book published by
Cambridge University Press.
