In sub-Saharan Africa, the past two decades have witnessed a phenomenal increase in the use of mobile phones which has attracted diverse research. This paper explores mobile phone use and livelihood activities in some urban and rural areas of Ghana. Qualitative data were extracted from a larger study that covered 24 sites ranging from urban to remote rural locations in Ghana, Malawi and South Africa. The Sustainable Livelihood Framework provided guidance for the study. The main findings of the study indicate that mobile phones provide direct phone-related employment and indirectly enable some others to secure jobs through contact with friends/relations and also facilitate marketing of farm produce in terms of reduction in transaction cost, access to ready market and contacts for better prices for produce. Additionally, phone use enhances job organization through communication between apprentices and their bosses and also facilitates the migration process of some irregular migrants. As a livelihood capital, mobile phone has the potential to reduce vulnerability and improve upon people’s livelihood outcomes. There is therefore the need to make mobile phones more affordable, expand mobile phone network coverage and improve upon service quality to facilitate livelihood activities, particularly in rural areas of the country.  相似文献

Inequality seems to be a feature of all societies, but some are probably more equal than others. It is in Third World countries however where inequalities between particular areas, groups and individuals are most marked. The paper first traces the growing interest in both the study of inequality and the rural household as a focus of analysis. Some of the problems of measuring inequality are then considered and various indicators of inequality are examined with reference to empirical evidence from rural W Africa. The paper concludes that recent development strategies have often directly or indirectly led to greater rural inequality and makes suggestions as to how future projects might achieve greater impact in reducing the gap between rich and poor.

The rapid expansion of the mobile telephony sector in African countries has been accompanied by the establishment of a wide range of informal support businesses, mostly run by young people. Little is known, however, about the lived experiences of young entrepreneurs working in this rapidly changing, technologically-driven sector. Drawing on qualitative research conducted in Accra, this paper explores young people's experiences of running informal businesses within the mobile telephony sector, including the sale of mobile phones and accessories, repair and technical support services, and the sale of airtime and mobile money services. Fateful and critical moments relating to personal and family events, as well as social networks and structural factors, are shown to mediate young entrepreneurs' chances of success in this new ‘niche' economic sub-sector. Despite the challenges they face, the paper illustrates how many of these young people have been able to achieve financial independence, afford rental accommodation, provide support for family members, and establish and sustain households. The mobile telephony sector is shown to be offering young people the opportunity to carve out a living, facilitate transitions into adulthood, and even enable some to move up the social ladder. By highlighting the agency of this group of young people, and for some their success in achieving the status of adulthood through their hard work and ingenuity, this study offers an important counter balance to images of young people in sub-Saharan Africa as being ‘stuck' or in ‘waithood'.  相似文献

In this paper we examine the ways in which mobile phones are becoming integrated into the everyday life of older adults in the UK by drawing on research funded as part of the British New Dynamics of Ageing programme. Specifically we draw on a digital engagement survey and the life history narratives of older men and women resident in the East Midlands of England to illuminate the challenges of remaining digitally engaged in old age focusing specifically on mobile phone use, with particular reference to maintaining social connections with spatially dispersed family and friends. Growing numbers of older adults possess a mobile phone, but the degree to which mobile phone use has been integrated into everyday practices is variable. For episodic users a mobile phone is used to complement a landline, to keep in touch with family and friends when out of the house. For confident users the mobile phone is used in multiple ways, via a range of applications, it is an integral part of numerous aspects of everyday life.  相似文献

Recent years have seen an upsurge in the numbers of studies investigating the potential link between climate variability and conflict—and particularly so quantitative studies of this relationship—without reaching any consensus on causal pathways or main findings. This study sets out to explore what the main causes of conflict between resource-user groups in arid and semi-arid areas in Sub-Saharan Africa are, with a particular focus on renewable-resource scarcity. We conduct a comparative analysis of eleven high-quality case studies of the escalation into violence of disputes between pastoralists and farmers or pastoralists in the Western Sahel and East Africa. This enables us to identify the mechanisms underpinning the actors’ motivations. Our analysis shows that the nature of these conflicts is complex. They cannot be reduced to a stimulus (resource scarcity)–response (violence) relationship. We find that drought is a contributing factor in four of the conflicts, and that a poor rainy season plays a role in a fifth one. However, resource scarcity is never the most important cause and it does not explain well the differences in conflict intensity. The most important contributor to explaining different levels of intensity is when local autochthonous and exclusionary claims are coupled with national-level political processes.  相似文献

The present article examines the dynamic linkages between biomass energy consumption, capital stock, human capital and economic growth across selected Sub-Saharan African countries based on dynamic heterogeneous panels of a mean group (MG) and pooled mean group (PMG) techniques. The finding based on PMG as the preferred method reveals that biomass energy consumption, capital stock and human capital are statistically significant, which means aforementioned variables have positive significant impact on economic growth in the countries studied. When an alternative panel estimation techniques of panel cointegration, dynamic OLS (DOLS) and fully modified OLS (FMOLS) are applied, the result based on panel cointegration technique reveals that biomass energy consumption, capital stock, human capital and economic growth are cointegrated as null hypothesis of most statistics are rejected at 1 % level of significance. The finding based on FMOLS shows that biomass energy consumption, capital stock and human capital positively influences economic growth at 1 % level and same result is obtained from panel OLS. The result based on DOLS however reveals that biomass energy consumption and capital stock are significant at 1 % on economic growth while human capital is insignificant. Considering its positive effect on economic growth with little or no environmental degradation when compared with fossil fuel uses, consumption of biomass energy is more preferable in these countries therefore is the best option to adopt by the policy makers of Sub-Saharan African countries.  相似文献

Global exponential water demand has resulted in the quantity and quality of household water declining rapidly in recent years. Across Sub-Saharan Africa, many small to medium size towns growing at more than 5% per annum provide the region’s momentum for urbanisation. Owing to the dismal performances of water utilities companies, urban populations have tended to resort to diverse and unsafe sources of household water. Illustrating with the city of Buea in the coastal south west Cameroon, this paper examines the changing trends in water sources and the potential health risks to its populations. It relied on a blend of information ranging from reviews of relevant secondary sources, empirical data to field surveys and laboratory analysis. Key findings point to a high level of water misallocation and non-revenue water by the water utility company; a growing movement of households from the certified pipe-borne water source to unimproved sources as follows: 36% to springs, 20% to wells, 25% to water vendors, 27% to rainwater, and 22% to boreholes and only 11% from open streams to piped water. This has resulted in the presence of coliform bacteria in all alternative water sources in Buea, corroborated by hospital returns on water borne intestinal bacterial infections. Given the proven efficiency of water distribution via public pumps and smaller retailers, there is the urgent need for a change of the water distribution paradigm in small and medium size cities in Sub-Saharan Africa to increase access for more people than through the more costly home connections preferred by utility companies.  相似文献

A rapidly growing literature interrogates the social and economic impacts of various Reducing Emissions from Deforestation and Forest Degradation (REDD+) schemes in Sub-Saharan Africa. Less often, however, have scholars examined the necessary corollary of such initiatives; that is, both new and enhanced law enforcement initiatives to combat the global trade in illegal forest products and secure property rights to conserved forests. Drawing upon recent consultative experiences for relevant multinational agencies in East Africa, we critically analyze the emergent features of this additional ‘dark side’ of REDD+, highlighting in particular both its potential for ‘leakage’ effects on adjacent jurisdictions and deleterious implications for forest-dependent communities. Specifically, we highlight the ways in which such activities threaten to conflate illegal with informal trade in forest products; the ways in which they are potentially ill-suited for addressing the trade in charcoal as opposed to the trade in timber; and the incentives that they may provide for states to further marginalize indigenous forest-dwelling populations in the region. In doing so, we argue that this nascent synthesis of REDD+ and transnational law enforcement threatens to contribute significantly and regressively to the broader securitization of conservation in Sub-Saharan Africa and elsewhere.  相似文献

The current paper examines the relationship between health financing (public and out-of-pocket health financing), CO2 emission and health outcomes in 35 Sub-Saharan African countries for the period of 1995–2012. The panel unit root and cointegration tests are conducted as pre-tests, followed by the estimation of the parameters using the FM-OLS and DOLS techniques. The findings of the study show the importance of public health financing as one of the major factors that lead to better health outcomes, whereas the out-of-pocket expenditure is found to be harmful to population health since it leads to increase under-5 mortality rate. Although the results show a negative relationship between CO2 and health outcomes, still these results remain inclusive. In addition, the findings reveal the importance of socioeconomic factors such as income and education as key determinants of health outcomes.  相似文献

A Kuznets curve is the graphical representation of Simon Kuznets’ hypothesis that as a country develops, there is a natural cycle of economic inequality driven by market forces, which at first increase inequality and then decrease it after a certain average income is attained. The concept has been applied to environmental studies hypothesizing that the relationship between per capita income and the use of natural resources and/or the emission of wastes has an inverted-U shape. This paper presents a holistic study aimed at validating the applicability of the Kuznets curve to flood disaster. The focus is China and Japan. Both countries are prone to flooding and have experienced great economic growth. Data analysis detected the turning points of annual flood fatality in both countries, and the change in annual flood fatality with economic growth in both countries was found to match the Kuznets curve. However, the variation pattern of annual flood-caused economic loss was different between China and Japan. The difference may be partially attributed to the difference in residential characteristics between the two countries. Besides, it was found that climate change affected the flood-caused economic loss in Japan over recent decades. Furthermore, the variations in annual flood fatality and economic loss in the largest city of China were also analyzed.  相似文献

The classical model of continental accretion and progressive cratonization, starting with an ancient nucleus onto which younger orogenic belts are welded (onion skin tectonics), has dominated geotectonic research for many years and has received new impetus with the general acceptance of the theory of plate tectonics. It has also been applied to the geotectonic evolution of large Precambrian crustal segments such as Africa.It is demonstrated, however, that new structural, geochronological and paleomagnetic data from Africa provide strong evidence for the existence of large cratonic continental plates since at least the Early Proterozoic which were later transected by linear mobile belts and thus partly destroyed. Crustal reworking and rejuvenation in these belts now gives the impression of younger orogens surrounding ancient “nuclei”.The geotectonic evolution of Africa is therefore characterized by plate destruction rather than by plate accretion with progressive cratonization, and only the “nuclei” have escaped this process.Many phenomena in the African mobile belts seem to indicate processes involving little or no relative motion of crustal plates or crustal shortening between them, and there is as yet no evidence of former oceanic plates to have been generated or consumed. It is therefore suggested that large-scale dispersive movements of major continental fragments were uncommon or absent in the Early and Middle Precambrian.Widespread drift may only have begun during the Late Precambrian/Early Paleozoic Pan African Tectogenesis, eventually leading to a crustal evolution as envisaged by the modern theory of global tectonics.  相似文献

We examine the current ‘datafication’ process underway in low- and middle-income countries (LMICs), and the power shifts it is creating in the field of international development. The use of new communications and database technologies in LMICs is generating ‘big data’ (for example from the use of mobile phones, mobile-based financial services and the internet) which is collected and processed by corporations. When shared, these data are also becoming a potentially valuable resource for development research and policy. With these new sources of data, new power structures are emerging within the field of development. We identify two trends in particular, illustrating them with examples: first, the empowerment of public–private partnerships around datafication in LMICs and the consequently growing agency of corporations as development actors. Second, the way commercially generated big data is becoming the foundation for country-level ‘data doubles’, i.e. digital representations of social phenomena and/or territories that are created in parallel with, and sometimes in lieu of, national data and statistics. We explore the resulting shift from legibility (Scott, 1998) to visibility, and the implications of seeing development interventions as a byproduct of larger-scale processes of informational capitalism.  相似文献

Cell phones present new forms of sociality and new possibilities of encounter for young people across the globe. Nowhere is this more evident than in sub-Saharan Africa where the scale of usage, even among the very poor, is remarkable. In this paper we reflect on the inter-generational encounters which are embedded in young people’s cell phone interactions, and consider the wider societal implications, not least the potential for associated shifts in the generational balance of power. An intriguing feature of this changing generational nexus is that while many young people’s phone-based interactions, from their mid-teens onwards, are shifting away from the older generation towards friendship networks in their own age cohort, at the same time they are repositioning themselves – or becoming repositioned – as family information hubs, as a consequence of their phone expertise. The paper draws on mixed-methods research with young people aged c. 9–25 years and in-depth interviews with older age-groups in 24 sites (ranging from high density poor urban to remote rural) across Ghana, Malawi and South Africa.  相似文献

A persistent theme in land and agrarian studies is the appropriation of land and natural resources by mostly Western foreigners and the inequitable division of land and natural resources between Indigenous people and white settlers. It was this overt racial inequality in land ownership and the accompanying structures of oppression that led to the rise of liberation movements in Africa, South America and Asia. Most, if not all, land and agrarian reform programmes in the former colonies take the racial inequality in land as their point of departure. The same applies to the process of changing the inequalities in the use and ownership of natural resources such as wildlife, fisheries and forests. Whereas critical scholarship and social movements vehemently opposed the racialized nature of land dispossession, less attention has been paid to the persistence of racialized tenure systems. The silence on the racial character of land and natural resource tenure is rather surprising given that colonial tenure systems were based on race and racist grounds. This paper draws on examples from nature conservancies and communal land reform in southern Africa to argue that the dual land and natural resource tenure inherent from colonialism and apartheid remains intact in contemporary southern Africa. It also suggests that the democratic governments in the region and critical scholarship have failed to challenge the racialized character of land tenure. Instead, they continued to reinvent orthodox views of society and culture. Race seems to matter most in property regimes in the region in as far as it relates to equity rather than its initial categorization of people. The consequences of the persistence of the racialized tenure systems are that the success or failure of land and resource use and management reproduces racial explanations.  相似文献

This paper is aimed at examining the role of African Global Earth Observation System of Systems (AfriGEOSS) in Earth Observation (EO) mission cooperation on the continent of Africa. It discusses the importance of earth observation programs for developing countries as well as the benefits of international cooperative efforts. The paper further examined some collaborative projects on Earth Observation in Africa and their associated problems. It specifically looked at the EO data coordination initiatives such as the Spatial Data Infrastructure (SDI), GEOSS, Africa Discovery Broker, etc. It then situates AfriGEOSS in the context of African Space Agenda (ASA) with recommendations especially to the Africa Union Commission for the realization of ASA set goals. The paper reiterated that regardless of whether developed or developing, Earth observation information provides substantial benefit supporting economic development, decision making and policy implementation of all countries of the world. This is as a result of its multifarious benefits to humans in areas like agriculture, forestry, risk management, disaster monitoring, maritime, defence and security and natural resources management. Consequently, the paper argued that the numerous benefits from space assets have driven countries within the continent of Africa to either acquire or develop capabilities in space systems which is devoted to improving quality of life in general. The paper concluded that while space systems are expensive, there is need for continuity and sustainability as a result of its numerous advantages to the human’s society.  相似文献

Urban concentration (or primacy) and inequality (in size distribution of income) are expected to follow bell shaped curves through the development process. Spatial convergence (through investments in transportation etc.) is expected to precede income convergence. Using longitudinal data from six Asian countries (Japan, Taiwan, Malaysia, the Philippines, Sri Lanka and India) this paper shows that (i) the bell shapes for urban concentration and income inequality generally hold, and (ii) the temporal relationship between the curve peaks is determined by geographical factors (for urban concentration); income inequality is seen to be more policy amenable.  相似文献

Although governments are generally expected to provide environmental services such as sanitation and solid waste collection for their citizens, most (municipal) governments in Sub-Saharan Africa seem hardly able to take up this task. Without ignoring the lack of material resources resulting from poverty, there are other structural causes for this failure as well and related to the role of the state. Since independence, the state in Africa has been debated in political as well as in academic circles and opposing views can still be discerned today. While some promote a strong interventionist state which can effectively enhance development, others consider introducing network governance by involving various societal actors in combination with different levels of government a more promising alternative. After presenting an historical overview, in this paper I will summarize this debate and discuss future options for East African authorities for providing more effective and sustainable urban environmental infrastructures and services.  相似文献

This study explores the spatial transformation of urban South Africa since the ending of Apartheid rule two decades ago. It places this experience within the context of countries which have also gone through a “loosening” of political control and of related controls over spatial arrangements. The paper provides a discussion of South Africa’s spatial trends between 1996 and 2011, focusing on urbanisation; urban form; and socio-spatial segregation, and exploring the extent to which changes identified are shaped by the state, private sector investment, and the everyday actions of households and individuals. It shows that South Africa’s urban spatial transformation, post-Apartheid, is both idiosyncratic and comparable. The consequences of spatial controls, and of their loosening, have been diverse across countries, but also within countries. Loosening has led to differing relationships between state, citizenry and private enterprise, and to complex new crossing points between these groupings, affecting spatial change. In South Africa, significant trends have been: movement to the major cities where employment growth is stronger; levels of racial desegregation; and densification of parts of cities and towns, along with peripheral growth and employment decentralisation. Many of the changes however are differentiated across space and between settlements. While proactive state policies have had some impact (not necessarily in the direction of desired spatial transformation), and there are complex interrelationships, our empirical studies suggest that the major weight of evidence is towards the roles of private enterprise and people in shaping spatial change, enabled in part by forms of state loosening.  相似文献
