I am passionate about bringing evidence of the contribution of agro-ecology to food security, climate change adaptation and mitigation. I am an agronomist by training. I have worked five years in Mali for the Internation Crops Research Institute for the Semi-Arid tropics, where I was experimenting together with farmers on integrated soil fertility management and diversification with legume crops. I am now working with CIRAD in Zimabwe, looking at the potential of agroecological practises to contribute to reducing food insecurity, while bringing benefits for climate change adaptation and mitigation. I have significant experience in the use of crop simulation models, to help design and assess relevant cropping systems.
