This article uses case study evidence from Makua and Manganeng, two rural villages in the Capricorn region, to investigate the effects of private and social costs, such as land degradation, on rural livelihoods in the area. Information is derived from household surveys, key informant interviews, participatory appraisal techniques, and a detailed ecological baseline study of the area. Livelihood activities such as agricultural practices (crop and livestock production), and wood and edible product gathering are included. This article attempts to synthesise the information gathered and lessons learnt from these studies, quantifies the contribution of these livelihood activities in monetary terms, and considers the implications for sustainable livelihood practices. The study finds that non-cash earnings contribute an important component of overall household income - between 40 and 50 per cent before social and opportunity costs are deducted. However, external costs significantly undermine overall earnings from natural resource-based products.

ABSTRACT Rhino populations are at a critical level and new approaches are needed to ensure their survival. This study conducts a review and categorisation of policies for the management of rhinos. Twenty-seven policies are identified and classified into in-situ (reserve-based) and ex-situ (market-based) policies. The policies are then evaluated based on four target areas: poachers/hunters, consumers, intermediaries and the game reserves themselves. The study finds that protected area management policies seem most beneficial in the short run, in particular the enforcement of private property rights over resource utilisation, as well as the establishment of wildlife sanctuaries that act as sustainable breeding grounds for rhino populations.
