This sounds amazing, but at the same time, I am concerned about the rain forest. Obviously more economically useful crops would accelerate repurposing the rain forest. Maybe the world would need to subsidize Brazil more to keep the rain forest? And could Brazil be expecting more subsidy with this development?
I wouldn't worry about the rain forest since. Not only it's likely too wet and hot for the new wheat cultivars, but AFAIK deforestation in the Brazilian Amazon is driven mostly by cattle-ranching and land speculation.
