This paper analyzes the human–nature interaction in a village in rural South Africa. It discusses preconditions, perceptions, and consequences of natural resource use, and places these findings into a regional and historical context. Applying an interdisciplinary perspective, the study uses interviews, questionnaires, remote sensing, and participatory mapping to analyze land cover changes and local perceptions of the environment. The study area is located in a former homeland (Transkei), a setting where well-recorded conflicts in the human–nature sphere have previously been triggered by population pressure, apartheid policies, and other historical, political, and social reasons. A small-scale and subjective conceptualization of environmental security is used as an approach to analyze local livelihood strategies in a selected village. The results indicate that the environment is not the highest priority in local survival strategies. Instead, formal and informal jobs and governmental grants are the most important security strategies. There are thus no major conflicts resulting from the interaction between the local population and the natural resources in this specific area. Explanations to this pattern can partly be found in historical contexts, which include apartheid policies, re-localizations, and a system of migrant labor. The study also suggests that general truths about a region such as Transkei might be misleading in specific localities. For relevant and successful environmental management and development planning however, it is crucial that decision-makers be able to get a clear picture of local situations and adjust their plans accordingly.  相似文献

This paper examines the 1998–2000 'border' war between Eritrea and Ethiopia and its continuing legacies from the perspective of food security.1 Focusing on the food crisis that hit both countries during the same period and was allowed to develop into a famine in southeast Ethiopia, it argues that this was linked with the war in more ways than hitherto recognised. Such connections can be appreciated only by taking a longer-term view of the decline of the rural economy of which this food crisis was part, factoring in the role played by this and other conflicts that have flared up in the region. An analysis of this kind might have helped donors and aid agencies to respond more effectively both to short-term humanitarian needs in the midst of an inter-state war and to the need for longer-term support for food security in a region beset by endemic conflict.  相似文献

Lead levels in different environmental media (soil, grass leaves, water, ceramics, pencil, paint, crayons and cosmetics) were determined to assess the major sources of lead exposure in Thohoyandou, South Africa. Soil and plant leaves were used as indicators of Pb pollution from vehicle exhaust emissions. After digestion with concentrated acids (HNO3, HCl and HClO4) Pb concentrations were determined in triplicate using a flame atomic absorption spectrometer. The mean Pb concentrations at the kerb of selected busy roads were 205.5 ± 90, 273.0 ± 90 and 312.8 ± 81 μg g−1 and 154.7 ± 67, 182.9 ± 76 and 240.6 ± 66 μg g−1 for soil and plant leaves (dry weight) respectively. These concentrations were substantially higher than the values found on soils 50 m away from the roads (97.4 ± 11 μg g−1). Pb concentrations in plants collected further away from the road (50 m) were substantially lower (71.8 ± 9.0 μg g−1). The observed levels on soil are lower than the UK critical value of 500 μg g−1 for gardens and allotments; and 2000 μg g−1 for parks and open space as well as the Canadian values for agricultural (375 μg g−1), residential (500 μg g−1 and industrial (1000 μg g−1). From these data it was clear that Pb concentrations in soil samples were substantially higher than the levels obtained for plant leaves. The Pb levels in green crayons, blue crayons, pencils (from China & Germany), were 10650 ± 75.2, 8200 ± 52.4, 1160 ± 50.2, 79 ± 10.1 μg g−1 for the inner contents; and 4870 ± 58.1, 5650 ± 55.5, 1950 ± 46.6, 60 ± 12.9 μg g−1 for the outer surface paint respectively. The ceramics showed Pb levels of 630 ± 50.3 μg g−1 (saucer) and 560 ± 32.2 μg g−1 (cup), while the inner contents and outer surface paint showed 480 ± 32.4 and 318 ± 21.2 μg g−1 of Pb respectively. Early morning tap water flush gave a Pb level of 20.6 ± 5.6 μg Pb l−1. This value is higher than the WHO and FDA maximum permissible concentrations of 10 μg l−1 and 15 μg l−1 respectively.  相似文献

This article discusses ways in which the South African Government and grassroots organizations envisage and implement democracy achieved since 1994 in the field of water resources management. The focus is on the democratic, political and economic freedom and equality in resource rights for poor black women, who are central to poverty eradication. While the new water policy and law provide an enabling framework for achieving these goals, implementation on the ground encounters both new opportunities and constraints. This is illustrated by several cases of establishing South Africa's new water management institutions: catchment management agencies and water user associations. The important nexus between state‐led democratization of water resources management and bottom‐up grassroots movements is also discussed. The article concludes that the Government's affirmative and targeted intervention is indispensable for redressing gender inequalities and eradicating poverty.  相似文献

Theoretically, a resource rent tax is neutral in that it does not influence the allocation of resources. However, the application of such fundamental principles in the tax formula of the South African gold mining industry negates the neutrality principle. A progressive element in the tax rate encourages mining of submarginal ores - leads to misallocation of resources. However, it substantially reduces the financial risks of a mining company engaged in the extraction of a commodity characterized by price volability, such as gold, and permits economies of scale in mining and encourages conservation of a non-renewable resource. As long as prices increase faster than costs, the advantages of this system probably exceed the disadvantages. The choice of the threshold rate in such a tax system is critical. If it is too high it will encourage mining of submarginal ores, and if too low it does not recognize the peculiar risks of gold mining investments.  相似文献

Pigeonpea is a tropical grain legume grown mainly in India. Though largely considered an orphan crop, pigeonpea has a huge untapped potential for improvement both in quantity and quality of production in Africa. More than any other legume adapted to the region, pigeonpea uniquely combines optimal nutritional profiles, high tolerance to environmental stresses, high biomass productivity and most nutrient and moisture contributions to the soil. The legume can be utilized in several diverse ways while the high genetic variability that exists within the cultivated and wild relatives remains to be explored for further uses. This article highlights the need for popularizing pigeonpea as a major legume crop in Africa. The main constraints to productivity are discussed and recent breeding efforts in Africa highlighted. Important opportunities for improvement are further provided.  相似文献

The long‐term integrity of protected areas (PAs), and hence the maintenance of related ecosystem services (ES), are dependent on the support of local people. In the present study, local people's perceptions of ecosystem services from PAs and factors that govern local preferences for PAs are assessed. Fourteen study villages were randomly selected from three different protected forest areas and one control site along the southern coast of Côte d'Ivoire. Data was collected through a mixed‐method approach, including qualitative semi‐structured interviews and a household survey based on hypothetical choice scenarios. Local people's perceptions of ecosystem service provision was decrypted through qualitative content analysis, while the relation between people's preferences and potential factors that affect preferences were analyzed through multinomial models. This study shows that rural villagers do perceive a number of different ecosystem services as benefits from PAs in Côte d'Ivoire. The results based on quantitative data also suggest that local preferences for PAs and related ecosystem services are driven by PAs' management rules, age, and people's dependence on natural resources.  相似文献

This paper analyses the relevance and potential of cash transfers as part of the disarmament, demobilisation and reintegration (DDR) assistance packages provided to ex-combatants in transitions from war to peace. To this end, a theoretical framework is established that permits the identification of the advantages and disadvantages of using cash in DDR. Subsequently, an empirical analysis is carried out to compare selected theoretical assumptions on the use of cash with the reality of lessons learned from recent experience in Sierra Leone and other African countries. The study shows that some theoretical drawbacks commonly associated with the use of cash in DDR processes may indeed bear out in practice. At the same time, though, the paper argues that the utility of cash transfers in DDR is affected by a variety of factors that go far beyond the simple choice of employing cash, most notably decisions on payment location, eligibility criteria and targeting.  相似文献

Scientists and global commentators watched African countries closely in the early months of the COVID-19 pandemic, predicting an impending disaster: the virus was projected to overwhelm already weak health systems. These expectations were informed by imaginaries of Africa as an inevitable site of epidemic disaster. This paper draws on accounts from Sierra Leone, Tanzania, and Democratic Republic of the Congo to contrast global catastrophe framings with everyday imaginations and experiences of crisis and crisis management. Utilising ethnographic research, the paper initially explores how COVID-19 was understood in relation to previous epidemics, from HIV (human immunodeficiency virus) to Ebola, as well as political conflict. It then considers how global crisis narratives both inform and are in tension with everyday collective and personal experiences. The paper brings these empirical reflections into a conversation with theoretical debates on the discursive construction of crisis and its effects, and argues that these tensions matter because crisis framings have consequences.  相似文献

Bridging the water infrastructure gap has become a major policy concern. In rural areas of Africa, access to water is as much constrained by territorial coverage as it is by the poor conditions of water points due to the difficulty in mobilizing communities for repairs. This paper examines the equity considerations of a rural water and sanitation programme in a district of Mozambique, and their impacts on the achievement of the programme's objectives. Our analysis underlines the contradictions in the conceptualization of equity in the design, planning and implementation of the programme. Even an explicitly pro‐poor strategy can fall short of delivering equity. Our findings stress the fact that overlooking local perception of equity can have a direct impact on the ability of a community to ensure the maintenance of their water points. They call for a careful definition of equity in the design of water programmes, as well as closer attention to this criterion as a precondition to achieving the long‐term objective of the programme.  相似文献
