How does a potentially devastating disturbance, such as drought or excess rainfall, effect the ripples of trade flow in sub-Saharan Africa? What is the spatial relationship between biophysical characteristics and net exports in a particular country or region? What do historical patterns and spatial variability in the environment, agricultural production, and natural shocks tell us about food distribution and possible mitigation through responsive trade flows? HarvestChoice explores these questions in a recently published chapter included in the flagship publication, ReSAKSS Annual Trends and Outlook Report (ATOR) 2013.

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.

The study presented here sheds new light on the link between the occurrence of weather shocks and violence by looking at the case of Sudan and South Sudan. Using geographically-disaggregated data from 1997 to 2009, it finds that higher temperatures greatly affect the risk of conflict.

To every crop there is a season with optimal times for planting, sowing, and harvesting. Precisely documenting these times in a Crop Calendar through time and space, however, remains a challenge, particularly at small scales such as the pixel. But pixels are what HarvestChoice is all about.

Stem rust is a potentially devastating fungal disease that can kill wheat plants and small grain cereals, but more typically reduces foliage, root growth, and grain yields. The pathogen multiplies rapidly, and its spores can be dispersed by wind over thousands of kilometers.

Risk: we all know what that means, right? But why is it such a critical part of our HarvestChoice portfolio, what does it mean when you look through the lens of farming in Sub-Saharan Africa?

We're not normally focused on this part of the world, but something like the Japanese tsunami tends to divert your attention.
