Spatially explicit models are becoming increasingly important tools for simulating land-use change. In this study, we formulated and tested models that incorporated spatial correlates of agricultural expansion and used them to predict local- and landscape-scale patterns of agricultural land-use change and its implications in the Maasai-Steppe of Northern Tanzania. We evaluated the relationship between agricultural land-use and its spatial correlates using Multiple Logistic Regression on data derived from satellite imageries for the year 2000.

The 2009 drought in Kenya has had a devastating effect on pastoralists. Hundreds of thousands of cattle died and with them a way of life that had provided families a livelihood from the land. We met Lawrence in a quarry just out of of Nairobi. For many generations his family have reared cattle on the rangelands of Kitengela. Now he shifts rocks in order to pay his way through University and the dream of a better life.
