Challenges ahead
in Luxembourg?
(Source: http://voileluxembourg.canalblog.com/albums/vidange_lac1991/index.html)
17
Challenges ahead in Luxembourg?
1. Increase of demand due to
• Demographic development
• Economic development (industries, e.g. FAGE, Google)
• Food production
2. Decline of resources due to
• Climate change (precipitation, vegetation periods)
• Pollution (pesticides)

Water management scenarios in 2050 ?
1. Smart sustainability
• ICT driven control and monitoring of stocks and flows.
• Water cycles are closed, using smart technologies.
• Negative rebound effects from economic and demographic growth on natural water
bodies (pollution, overconsumption) are observed.
2. Common good
• Production and consumption of water is managed in a holistic way at river basin level,
respecting the natural cycles.
• Different technical and managerial solutions are implemented in the regions.
2. Web of life
• Natural water bodies have been restored and are strongly protected. Abstraction is
limited to a strict minimum.
• Water and related nutrient flows and stocks are managed in a holistic way, inspired
by nature.
• Water use for technological purposes is expensive and organised in closed loops.
