| Abstract: | A transdisciplinary synthesis, grouped into four main themes, of the key papers in this Special Issue on Namaqualand is provided. Perspectives on current environmental, economic and social issues in the region are interpreted in the context of the past and are used to inform future trajectories of change and development needs within the region. Firstly, in terms of the climatic and biophysical environment, Namaqualand's rich biodiversity is not uniformly distributed and is explained in terms of the spatially heterogeneous geological, pedological and topographical gradients that characterize the region. Spatial and temporal variation in rainfall over long time frames would also have promoted speciation within isolated, poorly-dispersed, leaf succulent populations. Future climate models propose a decrease in rainfall across the region with an associated reduction in livestock production. The second theme provides an historical perspective on changing land use practices in Namaqualand over the last 2000 years. It suggests that they have frequently been influenced by events originating far from the region such as colonial expansion, apartheid legislation and globalization. Local people, particularly marginalised communal farmers have had to adapt to these outside influences within an increasingly confined landscape that has progressively eroded their mobility and restricted their ability to utilise the spatial and temporal variability inherent in semi-arid environments. The third theme shows how livelihood diversification has been one of the key ways in which local people from communal areas have adapted to change. While farming makes up a relatively small part of the income of most households it enhances the resilience of livelihoods in the region. The fourth theme is concerned with land reform, conservation and restoration in Namaqualand. While a significant amount of land has been transferred to previously-marginalised groups, equitable access to these resources is lacking. An exclusively commercial orientation within the extension and development programmes of the Department of Agriculture further hampers the effectiveness of land reform as a tool for reducing levels of poverty in the majority of households in the region. Conservation initiatives could enhance livelihood options in Namaqualand but are viewed by some as being in competition with the state's land reform programme and are too recent to reflect significant regional benefits at this stage. While restoration is possible in severely degraded lands, the costs and operational difficulties in these event-driven, semi-arid systems are emphasised. Finally, this synthesis suggests that the important exogenous drivers of change in the 21st century are likely to be climate, biodiversity conservation initiatives, land redistribution and continued processes of de-agrarianisation as a result of macro-economic change. A focus on building institutions, encouraging livestock mobility within a significantly expanded commons and supporting livelihood diversification are some of the approaches necessary to address the development needs of Namaqualand. |
