Getting a head start on a small project that can power small desalination equipment with alternative energy can prove there is hope outside of the under water systems. It's only feasible if it's to support animal feed, this way camels don't need to graze and can stay in one area.
During my uni years I had direct contact (via proff.) to a small team in India who built a desal plant that operated on solar power. These things can absolutely be set up on a small scale, and they are not expensive relatively speaking. There's also an opportunity to dose the hard-water in many of our Somali towns.
We just need enthusiastic diaspora engineers who are willing to dedicate time and effort - funding would be easy if we look at Somali remittance numbers across the world.
