Could these also be used to help keep dry areas greener to help wild-fire prevention?

Several of my friends and colleagues who live and work in Southern California area, have been effected by the recent wildfires.

I wondering if using Demilune semicircular bunds for wild-fire prevention.

Local ‘fire steady’ vegetation, planted in bunds may help areas effected by aridity and drought.

This would slow wild-fire. Fire burning through green vegetation could prevent spread as opposed to the current arid brush and grass that act as tinder.

Flooding has also become a huge problem in Southern California. My hope is that ‘Sahel style’ Water-retention Bunds may help California in a natural, chemical free, sustainable method.
