We have pretty much the same climate here and I followed what was going on- including that they wanted to tap into the aquifer - which will take forever (way longer than our lifetime) to replenish.
Permaculture is needed for sure...
Actually, we are about 200km/2 hours drive from Cape Town so we were not facing day zero. Our village is in a rain shadow but the mountains bless us with water. That said, were are, anyway, much drier than Cape Town - semi-Karoo and water conservation should have been be implemented sooner. We still have some restrictions. Too many people in the village have sunk/sinking boreholes on plots that are really relatively small. It's going to have an impact. Small plots: permaculture is not very doable. That said, the principles do apply.

Well, actually, even on a small plot all the water can be harvested - from roofs and such. If not in tanks, at least in the soil. And all water can be used twice. First in the house, then on the plants. Compost toilets eliminate a lot of water usage, growing food in closed systems like aquaponics or grow towers use very little water and the food is not being shipped, packaged and all of that...
It is surprising what all can be done 😄
I get you. We are actually quite urban. Erfs are 1000 sq m and quite regulated. Conservative. We compost and harvest what we can. Dew is a rarity when we need it most. All of that said, we wouldn't change things. Have a looooooong to do list! Lol
