HarvestChoice is interested in developing global indices that capture the level of sustainable intensification in agricultural systems. We are exploring the utility of Net Primary Productivity (NPP) as a co-indicator of environmental impact and ecosystem services. This post describes the rationale and some of our findings from a pilot study recently completed by our team.

With limited resources to cope with weather variability, smallholder farmers in Sub-Saharan Africa (SSA) are facing highly unreliable crop production from year to year. In this modeling exercise we quantified how much area is under such condition and what are their production potential under intensification. The simulation result indicates that, without further intensification, only 15% of current maize growing area has the potential to reliably produce more than 3 t/ha, a yield level suggested as being sufficient to sustain the cereal needs of a typical smallholder household. However, with well-managed intensification, 82% of the current maize area showed the potential to reliably produce 3 t/ha or more.
