It didn't take genetic engineering or charities doling out vitamin pills for children in Mozambique and Uganda to get more Vitamin A in their diets. It just took introducing a tasty crop similar to one people already grew and ate - orange fleshed sweet potatoes as opposed to pale ones - and working the women's networks with a fun campaign (theatre and song) to promote it.
The results are truly remarkable. Two thirds of the households targeted adopted OFSP.
It all made me think about my tree collard - another good source of Vitamin A that's easy to grow in mild climates and provides a continuous supply of greens under tough conditions.
Golden rice was never necessary, except in the minds of some bio-engineers with messianic longings. How often the best solution is the simplest and the closest.
