Climate change is putting our water system under pressure: longer droughts, heavier rainfall and a landscape that drains water too quickly. Hydrologist Kobe Hostyn explains why Flanders needs to rethink how it deals with water.

How do you retain water in a landscape where agriculture, housing, nature and infrastructure all compete for space? It starts by looking closely: in the field, through map layers and measurements, but above all by understanding the full system. That reveals both bottlenecks and opportunities, not as isolated pieces, but as a solid basis for clear, neutral advice that helps public authorities move forward.

Around Berchem Station, the challenge becomes very real: how do we give rainwater a proper place in the city again? Not through isolated measures, but through a considered approach that brings together water, drought, heat, biodiversity and public space. From the 'Putteke van Berchem' to Antwerp’s neighbourhood plans, smart analysis and strong design show how climate adaptation can also improve everyday quality of life.

A cloudburst is no longer a theoretical worst-case scenario. Flanders is already feeling how vulnerable its water system has become, from the Dender Valley to the Kalmthoutse Heide. Kobe Hostyn explains why restoring valleys, retaining water for longer and working across boundaries are key to helping our landscape absorb and hold water again. Not only to reduce flood risk, but also to tackle drought.

Curious how major landscape decisions and small upstream measures can work together?
