We Europeans take water for granted. Barring the occasional ban on using hosepipes during heatwaves, we use as much water as we like, when we like. It won’t be like that for much longer. Climate change has already forced many cities in Europe to drill even deeper for groundwater. Within the next decade, Europeans are likely to face the twin dilemmas of either too much or not enough water, as both droughts and floods become more frequent and extreme. As with other precious commodities, the question of access to this water will become intensely political. By and large, policymakers are yet to treat water supply with the importance it deserves. Projections show that already by 2025, 1.8 billion people will live in countries or regions facing absolute water scarcity. Yet only 5% of international climate finance is allocated to climate adaptation, and 1% to protecting and providing clean water for vulnerable communities.
