According to Waite, over the last few decades, farmers in Niger have managed the natural regrowth of native Faidherbia trees across 5m hectares. The Faidherbia fixes nitrogen in the soil, protects fields from wind and water erosion and contributes organic matter to soils when its leaves drop. Compared to conventional farms in the country, yields of maize in these agroforestry systems can be doubled and farmers in Ethiopia, Kenya, and Zambia are taking note.

But for the next wave of research breakthroughs, the FAO has estimated that we will need $45-$50bn annual spending globally. It's currently at $4bn.
