For the poster assignment of Water 1 (HWM10303), I chose to analyse the drought in the Veluwe. The poster contains all parts of the assignment. This poster is meant for inspiration and for coming up with topic ideas.

There are multiple measures that can be taken to
reduce precipitation deficits. For example, it is possible
to replace coniferous forests by deciduous forests or
heathlands[3], which will result in a decrease of
desiccation. Also, it is possible to plant deciduous forest,

Conclusion
The Veluwe is home to 1.1 million people[1] who depend
on clean drinking water that is pumped up there. The
effects of climate change could jeopardise this. When no
measure are taken, the Veluwe will become prone to
desiccation, which will result in a loss of biodiversity and
economic setbacks. Measures as reforestation, replacing
coniferous forests by deciduous forests or heathlands
and creating policies to achieve these goals can
contribute to the preservation of the Veluwe.
