This document discusses approaches to watering peri-urban landscapes in more sustainable ways. It advocates designing landscapes using ecological principles to increase water retention and create more productive, resilient ecosystems. Specifically, it recommends placing vegetation and water infiltration nodes at all high points and ridges in the landscape. This would help replace current 'discharge' systems with 'recharge' systems that use biological and ecological processes to ensure long-term water, soil, and ecosystem security while providing amenities. The goal is to establish cities and towns as "forest ecosystems" with over 70% vegetation cover, high biocapacity, and integrated peri-urban areas.
