In other words, to create spaces and infrastructures capable of absorbing, retaining, and releasing rainwater in a way that allows it to return to the natural water cycle without causing damage. In addition to heavy rains, longer periods of drought are also effects of climate change. Kongjian Yu explains that, in cultivable areas, reserving 20% of the land to operate as a reservoir system is sufficient to prevent the rest of the plot from being flooded. This area can also be adapted for moisture-resistant crops and to later supply the remaining plantations during dry seasons.

These spaces offer another benefit, which is the creation of green areas, parks, and habitats for animals, purifying surface runoff water with plants that remove toxic pollutants and nutrients.
