Set up biodiverse “pocket parks” and rain gardens. Pocket parks and rain gardens capture rainwater and allow for better water infiltration into soils, and increase soil health and groundwater recharge. Grow an inexpensive Miyawaki Forest in your urban habitat (shown: Clifton Park in Karachi), with native plants, pollinators and biodiverse animal life. If there’s not much space, you can start with as little as 1,000 square feet (around six parking spaces).
