In the 21st century, many people have cell phones. This is true even in Tanzania, the focus of a recent IFPRI survey, where 35% of farm households report having mobile phones in 2007. Using technology, we can reach these farmers in a faster and less expensive way by sending surveys directly to their mobile phones.

One of the things we are working on at HarvestChoice is the diffusion of agricultural technologies. A number of papers include maps that show how a technology moves across areas and we have also begun to construct similar maps for Tanzania using agricultural census data. By better visualizing the diffusion of technology throughout Tanzania, we hope that this will spark more conversation about what might be influencing farmer decisions in sub-Saharan Africa.

In the era of big data, unmanned drones, and satellite remote sensing, our knowledge of crop growing locations remains surprisingly limited. We have even less information on crop yields that vary from plot to plot. While some developed countries have started to map their crops, most developing countries have no such capacity. Information on the distribution and performance of specific crops is therefore mostly available through national or sub-national statistics, which are often too general for a focused analysis.

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.
