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.

"... (A) grand African paradox was beginning to form in Kenya: food shortages and surpluses side by side, simultaneous feast and famine. Drought was spreading in the northern and eastern reaches of Kenya, threatening herders and their livestock. The government declared a food shortage in the country and said it would be necessary to import food, either by purchasing from neighboring countries or inviting food aid, to feed the growing ranks of the hungry. ... At the same time, farmers in the breadbasket regions of western Kenya and the Rift Valley were complaining about the low prices they were receiving for their maize."

Characterizing global production systems just got easier. IFPRI/HarvestChoice has updated SPAM, from circa 2000 to centering on the year 2005. That’s right; SPAM 2005 is out for release and freely available to the public. That means more accurate and up-to-date spatially disaggregated crop production statistics and more of it.

Capturing the heterogeneity of VoP (Value of Production) across sub-Saharan Africa in a spatially explicit way is another example of what we do at HarvestChoice. Because informed decision making in agricultural development doesn't just rely on knowledge of important indicators, but a geographical context of where.

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.

Where in sub-Saharan Africa is the difference between actual and potential yield of maize most striking? We can answer this question pixel by pixel, region by region, but for the purpose of this brief analysis, let’s talk countries.

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.
