I have been living in the city of Leiden for three years now and fell in love with the canals, the old streets and buildings and the little parks here and there. This beautiful scenery will however not last very long. The streets are subsiding, the city centre is heating up and water related problems are occuring. And these problems will only become more intense since the climate is changing due to global warming. There will be more tropical days, meaning that the heatstress problem will become dangerous to weaker people, such as small children and the elderly. Next to more tropical days, there will also be more heavy rainfall. Currently, with all the stone and little green in cities the amounts of water get to large and streets and buildings will flood, giving large damage costs. So, it is necessary that Leiden becomes climate adaptive.
This climate adaptation can be done by the munincipality who will force rules on the citizens to change. That however will be very hard and will not make the munincipality popular amongst their citizens. It is probably a better idea to have the initiatives come from the locals themselves. The munincipality can then help the citizens with expertise and subsidies.
There are already some local initiaves in the Netherlands that show great effort from within the local community. One of them is Amsterdam Rainproof, an initiative to decrease the water problems due to heavy rain in the city centre of Amsterdam. For instance, people can put rain barrels in their garden to collect the water. And the project encourages the citizens to add more green to their gardens so the ground and the plants can hold on to the water longer. More information can be found on their website. https://www.rainproof.nl/
Another local initiative is Operatie Steenbreek, it literally tries to break the stones in the city of Leiden. So, replacing stones by plants, the same kind of idea as Amsterdam Rainproof. Because, plants don’t only hold water but also lower the temperature of an area. This is important since we will have more tropical days and the heatstress will cause great problems. In the current situation, people still have a lot of stone in the gardens or balconies. If everyone would more their houses and direct environment greener, then the water and heat problems will drastically decrease.
This video below explains Operatie Steenbreek.
These are just two examples of local initiatives in communities to battle the problems that arise because of climate change. It shows that little changes can eventually solve a large problem. These kind of bottom up actions lead to more awareness amongst the citizen. This is a very important aspect in climate adaptation. The more people that think and act on possible solutions the faster we can solve the big issues. Because heatstress and water issues are serious problems that must be solved before they become a threat to our health.
