Using household survey data from rural Ethiopia, this study explores the role of mobile telephony in smallholder farmers' price expectation formations. The empirical findings suggest that farmers who own mobile phones and who reside closer to markets make smaller price forecasting errors. The ben...

An approach for combining remote sensing spectral measurements with an ecosystem model was presented in an accompanying article. The sahelian grassland ecosystem STEP model developed for that purpose was also described and validated. In order to fulfill a prerequisite for using coarse resolution ...

An approach to combining remote sensing spectral measurements with an ecosystem process model is presented. In this approach, the ecosystem model is not bound by the sole use of satellite data, but integrates the latter in an explicit formulation of the main processes of vegetation functioning. A...
