uTshani BuyaKhuluma––The Grass Speaks: the political space and capacity of the South African Homeless People’s Federation

The point of departure for this article is the contemporary tendency towards localisation of politics in the context of neo-liberal globalisation. Mediated through institutional reforms, political discourses and localised struggles, this localisation of politics produce new and transformed local political spaces. The purpose of the article is to examine the capacity of popular movements to use and transform such political spaces within the South African housing sector. This analysis is done through a combination of conceptual examination of political space and actor capacity and a concrete case study of the political strategies and capacities of The South African Homeless People’s Federation. The article argues that the Federation has utilised political relations at different scales to mobilise resources such as land and subsidies for housing for its members. It has also influenced the formulation of housing policies through its discourses and practical experiences with people-driven housing processes. In consequence the Federation’s ability to function as a civil/political movement has granted them a certain capacity to participate in the complicated process of turning de jure rights to adequate shelter into de facto rights for the urban poor as citizens of a democratic South Africa.     

The spaces of modernisation: Outcomes, indicators and the local government modernisation agenda

The modernisation of local government has attempted to reinvent central-local government relations by offering freedoms and flexibilities to facilitate the governance of local issues. At the same time, a shift to outcome focussed targets as a new form of governmental rationality allows central government to delimit these opportunities. Drawing on aspects of governmentality and actor-network theory, the paper explores the tensions between these modes of government. It argues that outcome focussed targets circumscribe the limits of local governance by offering a despatialised technology of government. Using a case study of Local Public Service Agreements, the paper highlights the problems 10 English rural local authorities have experienced in their attempts to construct and negotiate a series of local policy targets with central government. The paper shows how the spatial limitations of statistical governance conspire against the construction of targets which reflect local policy priorities. In conclusion we consider the extent to which these limitations are a deliberate act of control and consider the implications for agency within networks of governmentality.     

‘Where is the life in farming?’: The viability of smallholder farming on the margins of the Kalahari, Southern Africa

This paper investigates the ways in which national and regional policies relate to farming activities and concerns amongst the rural population in an area of southern Africa. The struggle to make a living through farming was a common theme to emerge from research about changing livelihoods in response to both variability in the environment and changes in policy. This local discourse echoed regional debates about land and agrarian reform in post-apartheid South Africa and the uncertain future of mixed farming in Botswana. It also raised broader questions about the viability of the future of small-medium-scale farming systems in rural areas in Africa, especially those within dynamic dryland environments such as the Kalahari. This paper looks specifically at the links between poverty and asset holding and aims to identify the ways in which people are or are not able to utilise or mobilise these assets in times of need. We argue that this can vary significantly between seemingly similar settlements, and similar households and that understanding this complexity is the key to recognising how future interventions many impact upon people’s lives. Too often, in the quest to produce understandings of poverty and livelihoods, the complexity, incongruity and reality of day-to-day practices are overlooked. Thus we seek to draw out the interactions between policy and natural resource use, and the capital asset changes involved in these interactions, which influence the sustainability of livelihoods and the differing levels of poverty and vulnerability.     

Neoliberalising subjects: The legacy of New Labour’s construction of social exclusion in local governance

Analysis of ‘neoliberalism’ in recent geographical work has usefully drawn attention to the manner in which certain political-economic ideas resonate with a diverse range of state projects, policy objects and socio-political imaginaries. Positioning neoliberalism as a multifaceted political phenomenon, scholars have explored its local manifestations: the embodiments of an express commitment to market exchange in specific geo-historical contexts. Key to this process, it is argued here, is the attempt to instil a series of values and social practices in policy subjects. This process can have lasting effects by virtue of being embedded in practices of governance at the local level, a dimension that has been given less attention in existing research. Using the implementation of the New Deals for the Unemployed and New Deal for Communities in Bristol as an illustrative case, this paper investigates this potentiality by positioning New Labour’s construction of social exclusion as a mechanism of neoliberalisation and exploring the legacy of the neoliberal values espoused in and through its social exclusion policies.     

From smallholders to transnationals: The impact of changing consumer preferences in the EU on Ghana’s pineapple sector

This paper explores the impact that a new type of pineapple, and subsequent changing consumer preferences in the Global North, has had on the livelihoods of pineapple growers in Ghana. The paper starts by tracing how research and development in Costa Rica by the world’s largest producers of pineapple, Del Monte and Dole, have resulted in a new variety MD2. This new pineapple type has been marketed in the EU through campaigns carried out by plantation companies via supermarkets. Consumer preferences have subsequently switched to MD2 away from the varieties which previously dominated the market, including the Ghanaian grown Smooth Cayenne. Ghanaian smallholders have experienced a dramatic drop in the demand for Smooth Cayenne and are unable to switch to growing MD2. The Ghanaian pineapple sector is consequently being restructured with large-scale pineapple farms, principally run by transnational companies, growing large quantities of MD2 for export. Through a detailed empirical study of the changing livelihoods of pineapple growers in two settlements in Ghana, we show how smallholders have been affected in differing ways as transnational companies have increasingly entered the market. Recent attempts to incorporate smallholders as producers of niche pineapple products are discussed. The paper illustrates the mutual benefits of linking global value chain analysis with livelihood analysis.     

Impact of synsedimentary metre-scale normal fault scarps on sediment gravity flow dynamics: An example from the Grès d’Annot Formation, SE France

Synsedimentary faults result in the direct interaction between tectonic and sedimentary processes at similar spatio-temporal scales. Sedimentological analysis of sediment-laden gravity flows in the northern part of the Grès d'Annot Formation (Sanguinière sub-basin, Col de la Moutière/Tête Ronde) has revealed the presence of fault scarps of metre-scale height. These synsedimentary fault scarps were sufficient to disturb the sediment gravity flow dynamics resulting in (i) a strong variation of the erosive behaviour of a concentrated flow and (ii) the transformation of a strongly stratified, laminar hyperconcentrated flow into a turbulent flow, in short distance (less than 500 m). These disturbances develop without the flows being deviated by the fault scarps but produce great facies heterogeneity, the least homogeneous facies (mixing sand and clay) being localized on the upstream obstacle side, the most homogeneous (massive sand) downstream.     

Age and autochthonous evolution of the Sunsás Orogen in West Amazon Craton based on mapping and U–Pb geochronology

The West Amazon Craton consists of rocks of the Sunsás Orogen and the Rondônia-Juruena Province. The Sunsás Orogen comprises the western part of the Amazon Craton in South America and is best exposed in eastern Bolivia and western Rondônia and Mato Grosso states of Brazil. The integration of available maps and isotopic data together with new U–Pb and Sm–Nd analyses from 20 samples (plus 55 earlier dates), establish the timing of geologic events in the West Amazon Craton from 1840 to 1110 Ma. To unravel the complex geologic history of the study area, we primarily sampled granitoids and gneisses to develop a better stratigraphy and secondarily to narrow the age gaps between known discordances. Four periods of orogenic activity are identified within the Sunsás Orogen: 1465–1427 Ma (Santa Helena orogeny), 1371–1319 Ma (Candeias orogeny), ca. 1275 Ma (San Andrés orogeny), and 1180–1110 Ma (Nova Brasilândia orogeny). Notable is the absence of an Ottawan orogeny (1080–1020 Ma) equivalent. In the Rondônia-Juruena Province three main orogenies are recognized: the Juruena (1840–1780 Ma), the Jamari (1760–1740 Ma) and the Quatro Cachoeiras (1670–1630 Ma). Post-Sunsás rocks include Rondônia tin granites, Palmeiral sandstones, Nova Floresta basalt, and alkalic pipes.All inherited U–Pb ages of zircon and all exposed pre-Sunsás rocks in Bolivia have ages that correlate well to the neighbouring Rondônia-Juruena Province. This fact, together with the absence of fragments of older, Archean and Trans-Amazonian crust, suggests that the Sunsás Orogen is autochthonous and evolved over a continental margin formed dominantly by rocks of the Jamari (1760–1740 Ma) and Quatro Cachoeiras (1670–1630 Ma) orogenies plus rocks of the post-tectonic Serra Providência Suite (1560–1540 Ma). Almost all granulites known in Eastern Bolivia and in neighbouring area in Brazil are not basement rocks, but were formed during the Mesoproterozoic and are mainly associated with the Candeias orogeny (1371–1319 Ma). Dated samples of the Chiquitania and Lomas Manechi Complexes in Bolivia revealed a variety of ages and types of ages (metamorphic, magmatic, and inherited) indicating that those two units require more study. There is no evidence for the existence of a Paraguá Craton or Paraguá Block, which is almost totally composed of arc-related granites also formed during the Candeias orogeny.The main difference between the Sunsás Orogen and the Grenville Orogen of Laurentia is the absence in Amazonia of an Ottawan-equivalent orogeny (1080–1020 Ma). The existence of age-equivalents of the Candeias and Santa Helena orogenies in Laurentia (Pinwarian orogeny and rocks of the Eastern Granite-Rhyolite Province and the Composite Arc Belt) indicates that the connection of the two continents may have started from about 1450 Ma. In addition, the two belts may not have been directly juxtaposed, but instead, that one may have been the extension of the other during the Mesoproterozoic. The possibility that Amazonia joined the southwestern part of Laurentia also provides a good fit for the Hudson-Tapajós and Mazatzal-Yapavai-Rondônia-Juruena Provinces. This possible link to Laurentia may have started during the formation of the Trans-Hudson Orogen and its correlative Rondônia-Juruena and Tapajós provinces from about 1900 Ma.     

Démantèlement des paysages cuirassés anciens en zones forestières tropicales d'Afrique centrale : formation d'accumulations ferrugineuses actuelles en bas de versantOld ferricrete landscape dismantling in Central Africa rain forest zone: formation of the present downslope iron accumulations

Present downslope iron accumulations were investigated in the rainforest zone in southern Cameroon. Six clay and Fe-hydroxide dominated patterns have been identified and occur on the lower part of hill slopes. They can be subdivided in three different sequences, related to gentle, moderate or steep slopes. They are discontinuous with respect to the dismantling zone of the old ferricrete cap formed at Cretaceous period. They show a gradual development from a soft Fe-crust (carapace) to a vesicular facies that will, with time, cover the whole landscape again. To cite this article: É. Temgoua et al., C. R.
