I AM CONVINCED THAT THIS IS POSSIBLE IN ALL THE DRYLANDS, USING DROUGHT-TOLERANT TREE SPECIES:
Prof. Dr. Willem VAN COTTHEM (Ghent University, Belgium)
One can start with one or more separate teepees (easier to achieve), and then, on the basis of the successes booked, go for the bigger constructions (living rooms), like the one shown in this article:
It would be an enormous advantage, particularly for nomadic populations, to find similar “refuges” (places or situations providing safety or shelter) here and there along the roads. A task for the local authorities with national (and international) support.
Impossible ? Come on, give it a try in some African, Asian and South American countries, and you will see: IT WORKS !
Just like it worked for the small teepee (“tipi”) I constructed in my own garden in Belgium, planting some poles of the drought-tolerant Navajo willow (Salix matsudana var. Navajo).
No more plastic greenhouses or tunnels needed : grow your own live greenhouse (a tipi or a tunnel) with branches of the drought-tolerant Navajo willow, also globe willow, or the Chinese willow (Salix matsudana). One can grow these willows with a minimum of water in the drylands, even in the desert.
Such a live greenhouse offers remarkable advantages : natural shade and higher air humidity inside because of the transpiration by the leaves.
In drylands or deserts people can easily grow plants, e.g. young fruit trees and vegetables, inside the greenhouse, which can also offer shelter against the sun heat.
Outgrowing branches of the willow can be pruned to construct progressively new greenhouses.
