The project you propose looks good on the surface, but to attempt to change the climate of an area over a long period of time, it should be a requirement to first consult with an ecologist to make sure you do not do some unanticipated damage to the fragile dryland ecosystem. A botanical census should be done before the start of the project, and at regular intervals throughout the project, to see if the changes in climate are really a good thing for biodiversity, or if all the increase in biomass is of a few species, possibly introduced ones, at the expense of others, especially native species which are addapted to the normal climate of the region and upon which local animal life depends.
To just blindly go ahead without any consultation with an ecologist and simply assume any added rainfall is a good thing is a sign of an outdated attitude towards the environment that has no place in the modern world. Like most other attempts to apply the Reich Cloudbuster, this one does not comply with modern standards of ecological knowledge and responsibility.
