Change detection is one of the primary applications of remote-sensing data, and many techniques have been developed during the past three decades. Although frequently criticized and despite many alternatives, due to its simplicity and intuitive manner, post-classification change detection still remains one of the most applied techniques. Many studies in the field of change detection analysis acknowledge, for instance, the impact of misregistration, inconsistencies in classification schemes or differences in methods for image interpretation.

With the growth of the biofuel complex, the concept of ‘marginal land’ has emerged as a term commonly associated with the promotion of agrofuels. Remote sensing and other data are used to globally characterize land as marginal based on predominantly biophysical features that render it ‘non-competitive’ for the purpose of commercial food agriculture.

This paper examines how tourism as a form of land use and economic development is a critical site of struggle over the meaning of neoliberalism, landscape and land rights in northern Tanzania. I examine two tourism arrangements in Loliondo: joint ventures between expatriate-owned ecotourism companies and predominately Maasai villages; and the leasing of a hunting concession on village lands by the central government to a powerful foreign investor from the United Arab Emirates.
