Why cewas?
The world is facing a global water crisis. Continuing population growth and urbanisation, rapid industrialisation and expanding and intensifying food and goods production are all putting pressure on water resources. Climate change exacerbates the problems of water availability.
- Water quality decreases globally (over-fertilisation, non-treatment of sewage, micropollutants and endocrine disruptors, etc.)
- Aquatic ecosystems are degraded and oceans overfished
- Changing consumption patterns lead to larger water footprints
- Increasing lack of water in quantity and quality results in limited development
- Food security and health are jeopardised
- Upstream-downstream conflicts increase within countries, regions or economic sectors (industry, agriculture, population)
The lack of sustainable use and management of global water resources undermines progress and development. Yet, integrated water management and sustainable sanitation are hardly implemented today, and synergies within different groups of interest are barely exploited. Once used, proper treatment and reuse of wastewater is, worldwide, the exception rather than the norm – despite the urgent need for water and nutrients in agriculture and the contamination of aquatic ecosystems. Different stakeholders (water suppliers, industry, agriculture, households, sewage management etc.) generally fulfil their water needs without taking into account the impact on other stakeholders. This lack of coordination leads to an overuse and waste of water resources.
