My interests lie in applying solutions that regenerate ecosystem processes and enhance agricultural production of nutrient dense food and other valuable products, in partnership with farmers and relying on minimal external inputs. A current research project is on the incorporation of agroforestry into dryland maize production by conservation agriculture in Zambezi region. A project being embarked upon is converting encroached bush into biochar and fungal dominated compost.
