A University of Leeds collaborative study has probed links between environmental change and famine – two problems perceived to lie at the heart of Africa’s current crisis – in the context of another all too often linked to the continent - warfare and civil unrest. Land hunger and environmental depletion in the aftermath of war are often cited as causes of famine that in turn will lead to further conflict. Is such a chain reaction really at work? Is there an inevitable causal link between environmental degradation and violent conflict?

Since the early 1970s, the position of pastoralists in West Africa's Sahel zone has become ever more precarious. Their plight is evidenced by rural-urban migration movements as well as the results of field surveys. The last major drought of 1983-1985 delivered a major blow to communities which derive most of their food and revenues from herding. In many rangeland areas there is civil unrest - even building to armed conflict in places - owing to mounting tensions between various pastoral groups.

In Accra, as in other cities where rural-to- urban migration has added to the pressure on land, methods for the management and storage of land registry data are inadequate. How can land administration processes be automated through the introduction of information technology (IT) and Geographic Information Systems (GIS)? What institutional changes must be put in place?
