Great Question!! I recommend the SWITCH training modules: http://www.switchtraining.eu/home/
And another document on adaptation (enclosed). The challenges are described in our own review, that has been specifically written for non-experts (the challenges of water, waste and climate change in cities) that can be found here: https://link.springer.com/article/10.1007/s10668-016-9760-4 or here https://www.linkedin.com/pulse/challenges-water-waste-climate-change-cities-kees-van-leeuwen/ and of course the Urban Water Atlas for Europe: https://www.linkedin.com/pulse/urban-water-atlas-europe-kees-van-leeuwen/
