Land Reform, Range Ecology, and Carrying Capacities in Namaqualand, South Africa

Abstract In South African rangeland management, there is a long history of using the notion of carrying capacity as a central planning tool for environmental conservation and agricultural modernization. Today, in the new South Africa, the “need” for livestock keepers to adhere to a defined carrying capacity in order to conserve rangeland resources and to achieve economic development remains an institutionalized “fact.” In this article, we use interviews, livestock and rainfall data, policy documents, and aerial photos to discuss the idea of carrying capacity as it is currently used in the implementation of land reform in Namaqualand in the Northern Cape Province. This article is a contribution at the interface of human ecology and political ecology, linking environmental issues to economic constraints, land rights, social justice, and values. Policymakers and extension services usually see carrying capacity as a purely technical issue. We argue that this is problematic because it gives privilege to environmental sustainability and to one particular perception of the ideal landscape at the expense of livelihood security and poverty alleviation. It also perpetuates the colonial myth that the private ranch system is an ideal one, independent of disparate production goals and unequal economic opportunities and constraints, and it ignores evidence going back more than half a century that the Namaqualand range is capable of sustaining livestock densities far greater than those recommended. The winners that emerge from the current policy focus on carrying capacity are the few emergent black commercial farmers as well as conservationist interests; the losers are the majority of poor stockowners in the communal areas.

The historical ecology of Namibian rangelands: Vegetation change since 1876 in response to local and global drivers

The influence of both local and global drivers on long-term changes in the vegetation of Namibias extensive rangelands was investigated. Fifty-two historical photographs of the Palgrave Expedition of 1876 were re-photographed and used to document changes over more than 130 years, in grass, shrub and tree cover within three major biomes along a 1200km climatic gradient in central and southern Namibia. We showed that patterns of change are correlated with mean annual precipitation (MAP) and that below a threshold of around 250mm, vegetation has remained remarkably stable regardless of land-use or tenure regime. Above this threshold, an increase in tree cover is linked to the rainfall gradient, the legacies of historical events in the late 19th century, subsequent transformations in land-use and increased atmospheric CO(2). We discuss these findings in relation to pastoral and settler societies, paleo- and historical climatic trends and predictions of vegetation change under future global warming scenarios. We argue that changes in land-use associated with colonialism (decimation of megaherbivores and wildlife browsers; fire suppression, cattle ranching), as well as the effects of CO(2) fertilisation provide the most parsimonious explanations for vegetation change. We found no evidence that aridification, as projected under future climate change scenarios, has started in the region. This study provided empirical evidence and theoretical insights into the relative importance of local and global drivers of change in the savanna environments of central and southern Namibia and global savanna ecosystems more generally.

One hundred years of separation: the historical ecology of a South African 'coloured reserve'

During the twentieth century, the 20,000 hectares commons surrounding the village of Paulshoek as well as the neighbouring privately-owned farms have been significantly influenced by evolving land-use practices driven largely by socio-economic and political change in the broader Namaqualand and South African region. Land-use practices in the communal lands of Namaqualand were based initially on transhumant pastoralism, then on extensive dryland cropping associated with livestock production under restricted mobility, and more recently on a sedentarized labour reserve where agricultural production now forms a minor part of the local economy. For the first half of the twentieth century, farmers on communal and privately-owned farms shared similar transhumant pastoral practices and both moved across unfenced farm boundaries. By the middle of the century, however, fence-lines were established and commercial farming on privately-owned farms was increasingly managed according to rangeland science principles. As the population grew in the communal areas, families gravitated to new ‘service’ villages such as Paulshoek and became increasingly dependent on migrant labour and state welfare. While the majority of former croplands are now fallow, many of them for decades or more, communal livestock populations have remained relatively high, fluctuating with rainfall. The impact of this history of land use can be compared with that of neighbouring privately-owned farms where low stocking rates, coupled with a variety of state subsidies, have had a very different environmental outcome. This article charts the environmental transformations that have occurred in the area of Paulshoek as a direct result of the region’s political history and the evolution of the regional economy. We present a variety of evidence drawn from archival sources, oral history, repeat aerial and ground photography, and detailed climate, cropping and livestock records to show that events far beyond the borders of Namaqualand’s communal areas have had a profound influence on their environments.

Contested land tenure reform in South Africa: experiences from Namaqualand

In South Africa the distribution of land rights remains a major manifestation and cause of injustice, only slowly affected by the constitutionally mandated programme of land restitution, redistribution and tenure reform. The Transformation of Certain Rural Areas Act 94, 1998 (Trancraa) is the first post-apartheid legislation to reform ‘communal’ land tenure. It applies to 23 former ‘coloured rural areas’ and was introduced in six areas in Namaqualand in the Northern Cape Province during 2001–2. In a different, contested process a Communal Land Rights Bill for the former ‘homelands’ was published in August 2002, adopted by Cabinet in 2003 and signed into law in July 2004. While the Communal Land Rights Act relies on ‘traditional councils’ with a majority of non-elected members, Trancraa was enacted in the context of the 1997 White Paper of South African Land Policy and focused on community choice and the role of municipalities. The consultative process in Namaqualand was driven by civil society organisations and community actors, but did not include the training, finance and development support needed to transform rural relations among people affected by unemployment, land scarcity and weak local organisations. To promote procedural and substantive justice, tenure reform must honour the human rights of equality, redress and land development support articulated in land policy and the Constitution.

LANDSCAPE CHANGE AND ECOLOGICAL PROCESSES IN RELATION TO LAND-USE IN NAMAQUALAND, SOUTH AFRICA, 1939 TO 2005

ABSTRACT This paper examines the consequences of land use on vegetation over a sixty-six year period, within various agrarian landscapes across the winter/summer rainfall ecotone in northern Namaqualand. We employ repeat ground and aerial photography and interviews with land users to elucidate the causal factors that explain environmental change and stability. Ecological literature on landscape change in Namaqualand has suggested that communal land-use is detrimental to vegetation cover and species richness. Our study shows that there have been very few changes in vegetation cover and species richness in cultivated and grazed communal areas during the last 65 years, but that there has been a regeneration process in the private and protected areas. We demonstrate that these different vegetation responses reflect different land management histories. This evidence suggests that the potential for increased vegetation cover and species richness in response to land-use change is higher than was previously assumed and provides a new perspective on the latent capacity of communal landscapes to regenerate from changes caused by cultivation and grazing pressure. The environmental history presented in this paper spans a temporal and spatial scale that elucidates the complex relationship between land-use, climate, soils and vegetation change.

Blow me down: A new perspective on Aloe dichotoma mortality from windthrow

BackgroundWindthrow, the uprooting of trees during storms associated with strong winds, is a well-established cause of mortality in temperate regions of the world, often with large ecological consequences. However, this phenomenon has received little attention within arid regions and is not well documented in southern Africa. Slow rates of post-disturbance recovery and projected increases in extreme weather events in arid areas mean that windthrow could be more common and have bigger impacts on these ecosystems in the future. This is of concern due to slow rates of post-disturbance recovery in arid systems and projected increases in extreme weather events in these areas. This study investigated the spatial pattern, magnitude and likely causes of windthrown mortality in relation to other forms of mortality in Aloe dichotoma, an iconic arid-adapted arborescent succulent and southern Africa climate change indicator species.ResultsWe found that windthrown mortality was greatest within the equatorward summer rainfall zone (SRZ) of its distribution (mean = 31%, n = 11), and was derived almost exclusively from the larger adult age class. A logistic modelling exercise indicated that windthrown mortality was strongly associated with greater amounts of warm season (summer) rainfall in the SRZ, higher wind speeds, and leptosols. A statistically significant interaction term between higher summer rainfall and wind speeds further increased the odds of being windthrown. While these results would benefit from improvements in the resolution of wind and substrate data, they do support the hypothesised mechanism for windthrow in A. dichotoma. This involves powerful storm gusts associated with either the current or subsequent rainfall event, heavy convective rainfall, and an associated increase in soil malleability. Shallow rooting depths in gravel-rich soils and an inflexible, top-heavy canopy structure make individuals especially prone to windthrown mortality during storms.ConclusionsResults highlight the importance of this previously unrecognised form of mortality in A. dichotoma, especially since it seems to disproportionately affect reproductively mature adult individuals in an infrequently recruiting species. Smaller, more geographically isolated and adult dominated populations in the summer rainfall zone are likely to be more vulnerable to localised extinction due to windthrow events.

Sophia Klaaste: self-portraits

The photographs of Sophia Klaaste comprise an intimate personal archive of South African rural life, a kind of street photography in a village without streets, recording a young woman’s transition from adolescence to adulthood in the context of a remote Namaqualand village. Sophia Klaaste first used a camera as a participant in a photography project in 1999. Her photos stood out for their freshness, sensitivity, composition and candid portrayal of village society. She was only 16-years-old at the time, and trying desperately to find outlets for her feral imagination and vivacious personality; photography was one way she found to make sense of her life and the world she inhabits. Today, her collection of photographs consists of more than 1000 images. They record more than a decade of village life from the perspective of a young woman growing up in the ‘new’ South Africa, documenting family, friends, village events – funerals, dances, birthday parties, the Debutantes’ Ball – as Figure 1.

plague spread from Dakar to Yoff, Thiès, and even to Kaolack and Djourbel. The total loss of life can be estimated in the range of four to eight thousand. After 1919, the plague became endemic in Senegal. Although medical officials eventually came to appreciate that the rat flea was the principal vector of plague, public health measures remained focused on the control of Africans’ movements. The temporary disappearance of the plague by the 1930s seems to have been owing to natural causes, rather than French colonial interventions. In 1944, during the Second World War, another major outbreak of plague occurred. The Americans stationed in Senegal made decisive interventions, using DDT and sulfa drugs, after prevailing in a series of politico-medical conflicts with the French. After 1945, the plague disappeared from Senegal. Gracefully written and well-researched, Black Death, White Medicine makes an important contribution to the field of historical epidemiology and opens wide new windows on the history of colonial Senegal.
