Lawrence Haddad, IDS Director, has written about the future of biofortification (and mentioned the STEPS Centre's work) on his blog, Development Horizons:
"To date, biofortification has relied on conventional breeding techniques and behavior change research to answer 3 questions: (a) is there a significant, in terms of human nutrition, variation in the micronutrients zinc, iron, provitamin A in naturally occurring varieties of rice, wheat, maize and tubers? (b) can these varieties be crossed with high yielding varieties so that they are equally profitable for farmers to adopt? and (c) will they be acceptable to consumers?
The evidence is accumulating and is looking increasingly positive on all 3 counts--but not for all crops and not in all contexts."
