"Climate change is a story about water. Too much, too little, at the wrong time." - Jesse Scott
In an earlier post, I mentioned how the frequency of extreme heat and extreme precipitation events will likely be the hallmark of climate change. Recently, I've been talking about the benefit of green roofs and shading on the urban heat island. Now I would like to speak to extreme precipitation.
Flooding in Accra, Ghana this past June left over 150 dead. This number comes from both those who drowned and the who died in a petrol station fire that was offering shelter. Source: Africa News Today |
Current adaptation strategies in these areas include weighing down possessions with bricks and sitting on the highest dresser with your family until flood levels recede. This is unacceptable in the 21st century. Communities need, at the bare minimum, (improved) drainage systems and waste disposal services, to prevent the drainage from getting backed up. I will not be covering the logistics of hooking these areas up to local disposal services. Instead, I will focus on sustainable drainage systems proposed for London that may help worldwide.
