This study presents an integrated framework for the analysis of options of agricultural development and natural resource management at the ecosystem level. Pujiang County in Zhejiang Province, China, is used as a case-study area. The IMGLP model is applied to maximize regional agricultural economic surplus and labor market conditions in Pujiang. The consequences of four poverty reduction strategies (intensification of production, diversification toward livestock production, land expansion, and exit from agriculture) are determined for a set of regional poverty and biodiversity indicators. Diversification seems to be the most promising poverty reduction strategy, but requires an efficient use of animal manure in cropping systems to avoid environmental problems. Improved nutrient management in cropping systems is effective in reducing the regional nitrogen surplus, but less effective in increasing per capita income. The exit strategy is beneficial for reducing poverty and achieving biodiversity, but may have important social consequences that are not addressed in this study. Further reduction of rural poverty is hampered by labor constraints during the harvesting period for high-value crops such as vegetables and fruits. These constraints can be overcome by intensive research and development in the field of agricultural mechanization.  相似文献

This paper describes features of the emerging nexus in South Africa between tourism, poverty alleviation and local economic development (LED) interventions. The South African experience of evolving a strong pro-poor focus in LED planning is distinctive in the international context of writings on LED. Pro-poor LED is increasingly the outcome of the application of measures and programmes that are linked to the approach of pro-poor tourism in both rural and urban areas of South Africa. Two studies are presented of Alexandra township, Johannesburg and the Madikwe Game Reserve in North West Province as examples of pro-poor tourism as a form of pro-poor LED. It is argued that the growth of pro-poor tourism initiatives in South Africa suggests that the country is currently a laboratory for the testing and evolution of new approaches towards the planning of LED that potentially will have relevance for other countries in the developing world.  相似文献

Signs of desertification in Africa in the 1970s and 1980s were closely linked to rainfall fluctuations. There may now be an upward trend in the Sahel, but climate change models do not yet provide reliable predictions of rainfall. As family farms become smaller under conditions of population growth, some people move to new areas or new occupations (urban population is growing much faster than rural) and farmers attempt to raise the value of output (crops or livestock) per hectare. Long–term data for selected countries and areas provide some evidence of positive trends. Case studies show that adaptive strategies of small farmers include techniques to improve fertility, conserve water, manage trees, increase livestock, and take advantage of changing markets. However, their investments in improving land and productivity are constrained by poverty. Governments can best help by improving market access and opportunities for non–farm activities. The region's climate is characterized by variable rainfall, which means that droughts will continue to occur unpredictably.  相似文献

Studies of the resource curse as it affects African states abound, yet few deal specifically with the experiences of South Africa. The inability of countries to convert natural resource wealth into income and improved development measures remains highly pertinent and is especially apparent in Africa's largest economy. This paper takes a unique approach to study the resource curse by comparing South Africa's political economy with the existing resource curse literature. Using data from international organisations, studies of poverty and qualitative evidence this paper examines South Africa's experience with mineral extraction. It is found that South Africa has experienced many of the symptoms outlined in the resource curse literature including relatively slow GDP growth, gross inequalities, entrenched poverty and the creation of a rentier state. Overall, it is concluded that South Africa has failed to benefit from natural resource wealth and can be classified as a resource cursed state. Not only has mineral wealth failed to benefit much of South Africa's population, sections of society have actually been harmed through the process of mineral extraction. This paper is the first to examine South Africa in light of the current resource curse literature and to conclude that the state far more closely resembles its sub-Saharan African neighbours than its upper-middle income peers.  相似文献

Much of Sub‐Saharan Africa is burdened with water scarcity and poverty. Continentally, less than four percent of Africa's renewable water resources are withdrawn for agriculture and other uses. Investments in agricultural water management can contribute in several ways to achieving the Millennium Development Goals of eradicating extreme poverty and hunger and ensuring environmental sustainability. Increased yield and cropping area and shifts to higher valued crops could help boost the income of rural households, generate more employment, and lower consumer food prices. These investments can also stabilize output, income and employment, and have favourable impacts on education, nutrition and health, and social equity. Investments in agricultural water management can cut poverty by uplifting the entitlements and transforming the opportunity structure for the poor. The overall role of investments in agricultural water management in eradicating hunger and poverty is analyzed. This paper contributes to the present debate and efforts to identify strategies and interventions that can effectively contribute to poverty reduction in Africa. It provides an overview of population growth, malnutrition, income distribution and poverty for countries in three case study river basins — Limpopo, Nile, and Volta. With discussions on the contribution of agriculture to national income and employment generation, the paper explores the linkages among water resources investments, agricultural growth, employment, and poverty alleviation. It examines the potential for expansion in irrigation for vertical and horizontal growth in agricultural productivity, via gains in yield and cropping area to boost the agricultural output. Factors constraining such potential, in terms of scarcity and degradation of land and water resources, and poor governance and weak institutions, are also outlined. The paper argues that increased investments in land and water resources and related rural infrastructure are a key pathway to enhance agricultural productivity and to catalyze agricultural and economic growth for effective poverty alleviation.  相似文献

Artisanal mining is to be viewed not only as an issue requiring mining expertise, but also as a socio-economic issue in the context of poverty, requiring multi-sectoral attention. This article traces global employment estimates in small-scale mining, outlining the extent and economic impact of small-scale mining in selected countries in Africa, Asia and Latin America. New approaches and developments are analyzed with special focus on the interrelated roles of government, the private sector, non-governmental organizations, lending institutions and the local communities. The flow of foreign capital, the creation of joint ventures, and the contribution of women are also discussed, as are strategies that have been implemented as well as recent developments including developments in the areas of health and safety.  相似文献

In this paper, we argue for the importance of incorporating a gendered perspective for the effective development of sustainable agricultural biotechnology systems in sub-Saharan Africa. Priority setting for agricultural policy and project development requires attention to gender issues specific to the demands of agricultural biotechnology. This is essential for successfully addressing food security and poverty reduction in sub-Saharan Africa (SSA). There has been a great deal of debate and literature on the implications of gender in agricultural development and policy. However, the implications of gender in agricultural biotechnology and have received relatively less attention, especially in SSA. Based on interviews with key stakeholders in agricultural biotechnology across SSA, review of pertinent literature and field observations, we have found that incorporating a gendered perspective is critical for the sustainable development of agricultural biotechnology and requires attention in five areas: the inclusion of women, particularly women farmers, in decision-making around biotech/genetically modified (GM) crop and trait selection; equal representation of women as men in education for agricultural science and in agricultural biotechnology research and development professions; greater involvement of women in extension services and farmers’ associations for successful delivery of information about biotech crops equality between men and women in access to resources for biotech/GM crop cultivation; and increased control for women farmers over biotech/GM crop management and income generation. We explain the consequences of failing to include such gender-responsive considerations into priority setting for agricultural biotechnology development and policy in SSA and provide recommendations for how policy makers and project partners of development initiatives can avoid such oversights.  相似文献

Summary The close links which exist between poverty, disease and development are surveyed, particularly with reference to the situation in Africa. Poverty may impede the correct use of the land which can in turn lead to malnutrition and a higher incidence of disease. A population in poor health cannot effectively improve its own economic condition or make full use of aid. Poor health may be due to a colonial heritage of unsatisfactory land use, inappropriate transfer of technology, short-sighted administration, or other causes. Not all development brings improvement in health, for instance, inadequate urban planning can induce health problems.The wealthy and secure nations of the world will realise that they cannot possibly remain either wealthy or secure if they continue to close their eyes to the pestilence of poverty that covers the whole southern half of the globe. They will act, if only to preserve their own immunity from infection.(McNamara, 1968)Paul Milligan, is a Research Assistant in the Department of Biological Sciences at the University of Salford.

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole.  相似文献

Semi-structured focus group interviews were employed to examine factors that affect the likelihood that resource managers in southern Africa will use information on vegetation fires provided by two satellite-derived products: an active fire product and a burned area product. The two products are updated regularly and aim to deliver the state-of-the-art in the global monitoring of fires from satellite remote-sensing. Both products are derived from data transmitted by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors carried onboard NASA's Aqua and Terra satellites. The active fire product can be accessed for free via the internet and on media by users working anywhere in the world; the burned area product will be accessible in a similar manner in 2006. The MODIS fire products provide systematic, near-global coverage and are freely available; as such, they give resource managers new opportunities to obtain or supplement information they need to manage vegetation fires effectively. However, the availability of these products does not mean that resource managers will use them, and many other factors are involved. To understand factors that affect whether southern African resource managers will use the two products, two focus groups were held with members of the Southern African Fire Network (SAFNet) in Malawi, Africa, August 2004. Analysis of the group discussions reveals a number of factors that influence whether they will use the products. The qualitative, in depth nature of the group discussions revealed 12 main factors that influence product use; not least the low international internet bandwidths for African countries outside of South Africa. Analysis of the group discussions also suggests how the uptake of MODIS fire products by resource managers in southern Africa might be enhanced by affecting specific changes to how MODIS products are packaged and delivered.  相似文献

This paper investigates whether and how World Bank mining sector reforms have fuelled the expansion of illegal artisanal mining activity in Sub-Saharan Africa. In doing so, the analysis examines three issues. First, the emerging correlation between reforms and poverty, mainly a result of increased unemployment caused by Structural Adjustment Programmes and concurrent privatisation of state-owned enterprises, is explored. Second, the possibility that reform of large-scale mining has decreased available land for peasant farming as well as legalised small-scale mining activity is discussed. Finally, the notion that the regularisation of informal mining activities has been an exceedingly bureaucratic procedure in Africa, therefore providing individuals with little incentive to operate within the legal domain, is examined. Faced with few employment prospects, a growing number of Africans are pursuing employment in the artisanal mining sector, a worrying prospect given its intimate association with environmental degradation and HIV/AIDS.  相似文献

In sub-Saharan Africa, Southern Africa is the most urbanized region. This dynamic is rapidly transforming the nature of Southern African human settlements which, in turn, has a chain reaction of consequences from negative environmental impact to the need to develop policy for the sustainability of the region's cities. This paper examines the relationship between urbanization trends and environmental change in Southern Africa, and then advocates and discusses priority areas of a managed policy framework for a more constructive approach to responding to the challenge of the sustainability of cities in the region. The paper concentrates on those countries that are members of the Southern African Development Community (SADC).  相似文献

Among the world's poor, approximately 75% of those in extreme poverty live and work in rural areas and two‐thirds of them depend mainly on farming or farm labour for their livelihood. Policies to grant the rural poor secure access to land and water for irrigation — and to improve the economic efficiency of small‐scale agriculture — can thus play a critical role in the implementation of rural development strategies, including efforts to combat rural poverty. Since inadequate access to arable land is probably the most important cause of rural poverty, redistributive land reform is increasingly seen as crucial for socio‐economic development and poverty alleviation in many developing countries with substantial amounts of (unused) arable state land or (under‐utilized) large private landholdings. This article argues that market‐based land redistribution schemes, such as the one being implemented in South Africa, can be considered one of the most innovative approaches to land reform that have emerged over the last decade. These schemes thus provide a useful alternative to more conventional, state‐controlled land redistribution programmes. The article concludes, however, that when countries opt for market‐based approaches to land redistribution, the State still has an important role to play, without necessarily deciding which land parcels change hands.  相似文献

Sub‐Saharan Africa continues to face the daunting challenge of alleviating poverty due to slow economic growth. In southern Africa, most countries are adopting policies that promote the integration of biodiversity conservation and rural development to contribute to rural poverty alleviation. Numerous approaches have been undertaken in this endeavour, including Transfrontier Parks (TFPs) and Transfrontier Conservation Areas (TFCAs). This paper discusses some of the limitations of the TFPs. In conclusion I posit that unlike TFPs, which are state controlled and managed, TFCAs, which promote multi‐land use and multi‐stakeholder participation are attainable and have a higher probability of sustaining biodiversity conservation and contributing to the alleviation of rural poverty, if: (i) areas of high biodiversity conservation within communal areas can be identified, zoned and leveraged to biodiversity conservation and managed in partnership between the communities and the private sector; (ii) local communities can secure legal rights to their customary land being devoted to biodiversity conservation and use such pieces of land as collateral in negotiating partnerships with the private sector in developing conservation‐based enterprises; (iii) functional community natural resource governance institutions can be established and empowered to represent their constituencies in securing fair equity from profits made from sustainable use of the conserved biodiversity assets and tourism businesses; (iv) concerted effort can be invested in developing and implementing family planning and fertility reduction strategies that would slow down human population growth to levels that can be sustained by the available natural resources; and (v) if sustainable financing mechanisms can be developed, and the governance of protected areas occurring in the TFCAs can be broadened to include other stakeholders.  相似文献

The Water Poverty Index: Development and application at the community scale   总被引:17,自引:1,他引:17  
The article details the development and uses of the water poverty index (WPI). The index was developed as a holistic tool to measure water stress at the household and community levels, designed to aid national decision makers, at community and central government level, as well as donor agencies, to determine priority needs for interventions in the water sector. The index combines into a single number a cluster of data directly and indirectly relevant to water stress. Subcomponents of the index include measures of: access to water; water quantity, quality and variability; water uses (domestic, food, productive purposes); capacity for water management; and environmental aspects.
The WPI methodology was developed through pilot projects in South Africa, Tanzania and Sri Lanka and involved intensive participation and consultation with all stakeholders, including water users, politicians, water sector professionals, aid agency personnel and others. The article discusses approaches for the further implementation of the water poverty index, including the possibilities of acquiring the necessary data through existing national surveys or by establishing interdisciplinary water modules in school curricula. The article argues that the WPI fills the need for a simple, open and transparent tool, one that will appeal to politicians and decision makers, and at the same time can empower poor people to participate in the better targeting of water sector interventions and development budgets in general.  相似文献

In recent years, policy mechanisms to support a formalized artisanal and small‐scale mining (ASM) sector in sub‐Saharan Africa have gained increasing currency. Proponents of formalization argue that most social and environmental problems associated with the sector stem from the fact that ASM is predominantly unregulated and operates outside the legal sphere. This paper critically examines recent efforts to formalize artisanal and small‐scale mining in West Africa, drawing upon recent fieldwork carried out in Sierra Leone, Ghana and Mali. In exploring the sector's livelihood dimensions, the analysis suggests that bringing unregulated, informal mining activities into the legal domain remains a considerable challenge. The paper concludes by confirming the urgent need to refocus formalization strategies on the main livelihood challenges and constraints of small‐scale miners themselves, if poverty is to be alleviated and more benefits are to accrue to depressed communities in mineral‐rich regions.  相似文献

Natural resource management is central to global efforts to reduce poverty and environmental degradation, and is one of the principal ways in which countries are seeking to advance sustainable development and the implementation of Agenda 21. But these efforts to advance natural resource management are strongly impacted by climate and by seasonal and inter–annual climate variability.
This article aims to further advance understanding of the relationship between natural resource management and climate variability, with particular attention to ways in which natural resource managers at every level — from the household to the national and international levels — can cope more effectively with such variability. In particular, the article provides an overview of the way in which efforts to manage natural resources to reduce poverty and environmental degradation are impacted by natural climate variability. It examines what natural resource managers are doing to cope with these challenges, and discusses the kinds of new approaches and partnerships that are needed to improve their capacity to cope more effectively with climate variability. In doing so, the article touches on the implications of future climate changes for natural resource managers and the way in which their efforts to cope more effectively with climate variability will provide opportunities to gain experience in identifying and adjusting responses to longer–term climate change.  相似文献

The fact that the artisanal and small-scale mining (ASM) sector in Ghana is driven largely by poverty means that the sector is a major source of livelihood for people in mining communities across the country. However, given the various social and environmental problems associated with the ASM sector, there is now an emerging consensus that the formalization of the sector would not only allow for these associated problems to be addressed but also ensures that the sector contributes to sustainable development and safeguard the livelihood of local communities. While a large body of extant literature has examined the challenges and opportunities facing the process of formalization, the question of the criminalization of the sector and its consequences for local livelihood has received only limited attention. Drawing from primary data collected during fieldwork in Ghana, this study examined the livelihood implications of the ban on galamsey in the Tarkwa-Nsuaem Municipality in South-Western Ghana from the perspectives of local communities and other key stakeholders. The study reveals that the ban on galamsey has imposed significant socio-economic hardships on the people and appears to be entrenching poverty rather than sustainable development. The study considers the theoretical and practical implications of the findings for sustainable livelihood enhancement in developing countries.  相似文献

Reservoirs are important for various purposes including flood control, water supply, power generation, and recreation. The aging of America's reservoirs and progressive loss of water storage capacity resulting from ongoing sedimentation, coupled with increasing societal needs, will cause the social, economic, environmental, and political importance of reservoirs to continually increase. The short‐ and medium‐term (<50 years) environmental consequences of reservoir construction and operation are well known and include an altered flow regime, lost connectivity (longitudinal, floodplain), an altered sediment regime, substrate compositional change, and downstream channel degradation. In general, reservoir‐related changes have had adverse consequences for the natural ecosystem. Longer term (>50 years) environmental changes as reservoirs enter “old” age are less understood. Additional research is needed to help guide the future management of aging reservoir systems and support the difficult decisions that will have to be made. Important research directions include assessment of climate change effects on aging and determination of ecosystem response to ongoing aging and various management actions that may be taken with the intent of minimizing or reversing the physical effects of aging.  相似文献

This paper uses a critical realist framework to analyse environmental risk in a local space. It argues that urban risk needs to be understood in terms of the causal mechanisms that shape risk events and the contingent conditions that provide the context within which they occur. It uses a case study of an informal settlement in Hout Bay, South Africa, to explore these ideas. It is an approach that challenges the dominant technical and scientific discourse that usually determines the understanding of risk. The research suggests that the key causal mechanisms that shape risk events in informal settlements are globalisation and urbanisation, poverty and vulnerability, the social construction of environmental problems, gender relations, the rise of civil society organisations, political governance and the spatial distribution of risk. The environmental characteristics of the site, as well as the development of the settlement during the political transformation in South Africa, are the key contingent conditions determining the nature of risk.  相似文献
