This is a long thread from permies.com relating to growing fruit trees in arid areas  from seed.   It seems that  trees grown from seed  are  more resilient to drought than  ones planted  as growing trees and do not require water at the time of sowing.  Of course it only works in areas that have rain at some  time of the year like Mediterranean areas that have rain in winter but are dry in summer.  If trees can be established they can give some shade to other food plants and if done on a large scale the effect is to retain moisture.   There are lots of areas in Africa and the Middle East that have suitable conditions, particularly the northern edge of the Sahara  and the area immediately to the south as well as  coastal areas of the Middle East.     Compared to the expense of   dealing with mass migration and conflict in many of the  drought affected countries the cost would be tiny.

It has long been the 'solution' as I remember when I was at school it was the taking point for fund raising during one term and that was over 35 years ago.

One issue I have since seem is that these tree use ground water to handle droughts, but vast amounts of fund raising today is focused on supplying pumps and depth well equipment because the water tables in many areas at risk have been lowered over time due to human activity.

Can't resist this.  If you haven't read 'The Man Who PLanted Trees' by Jean Giono please do.   Literature not science, but wonderfully evocative. And pretty much as per most reforestation ecology I've read.
