The Great Green Wall is ambitious in scope, but composed of relatively simple parts: capturing rain-water with berms, planting the right kinds of plants in the right order, and creating a system of ecologically sound incentives for people to participate in the project. It's wonderful to learn about.

Andrew Millison, the creator of the linked YouTube video, has an interesting channel where he essentially showcases applications of / advances in ecological technology (i.e., permaculture.) I take some solace in the fact that his videos get millions of views; suggesting that permaculture / ecological design principles aren't some fringe-y thing any more.
