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.

In recent years, private companies have acquired long-term leasehold titles to more than five million hectares of what was formerly customary land in Papua New Guinea (PNG), but hardly any of this land has been devoted to production of the four green commodities in which PNG might have some comparative advantage – sustainable palm oil, bio-ethanol, biodiversity and carbon credits. Nearly all of it is dedicated to so-called ‘agro forestry’ projects that appear to be short-term salvage logging projects justified by the promise of a purely virtual form of large-scale agricultural production.
