Inside the "African cattle complex": animal burials in the holocene central Sahara.

Directory of Open Access Journals (Sweden)

Savino di Lernia

Full Text Available Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological value well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in-depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi-dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC. This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art make the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O analyses of animal remains, and botanical information are used to explore this highly formalized ritual and the lifeways of a pastoral community in the Holocene Sahara.

Income-environment relationship in Sub-Saharan African countries: Further evidence with trade openness.

Zerbo, Eléazar

2017-07-01

This paper examines the dynamic relationship between energy consumption, income growth, carbon emissions and trade openness in fourteen Sub-Saharan African (SSA) countries. The autoregressive distributed lag (ARDL) approach to cointegration and the Toda-Yamamoto causality test were used to investigate the long-run and short-run properties, respectively. The long-run estimations give evidence against the environmental Kuznets curve (EKC) hypothesis in SSA countries. In contrast, the results highlight the significant and monotonically contribution of income growth and energy consumption in explaining carbon emissions in the long-run and short-run in several countries. Furthermore, the results show that trade openness enhances economic growth and is not linked to causing carbon emissions in these countries. Hence, a trade incentive policy may be implemented without harmful effect on the quality of the environment.

To estimate the sources of funds for health research (revenue) and the uses of these funds (expenditure). A structured questionnaire was used to solicit financial information from health research institutions. Forty-two sub-Saharan African countries. Key informants in 847 health research institutions in the 42 sub-Saharan African countries. Expenditure on health research by institutions, funders and subject areas. An estimated total of US$ 302 million was spent on health research by institutions that responded to the survey in the World Health Organization (WHO) African Region for the biennium 2005-2006. The most notable funders for health research activities were external funding, ministries of health, other government ministries, own funds and non-profit institutions. Most types of health research performers spent significant portions of their resources on in-house research, with medical schools spending 82% and government agencies 62%. Hospitals spent 38% of their resources on management, and other institutions (universities, firms, etc.) spent 87% of their resources on capital investment. Research on human immunodeficiency virus/tuberculosis and malaria accounted for 30% of funds, followed by research on other communicable diseases and maternal, perinatal and nutritional conditions (23%). Research on major health problems of the Region, such as communicable diseases, accounts for most of the research expenditures. However, the total expenditure is very low compared with other WHO regions. © The Royal Society of Medicine.

Sub-Saharan African countries' economic development is dependent on energy consumption. This paper assesses total energy demand, which is composed of traditional energy (wood fuel) and commercial energy (electricity and petroleum), in the Central, East, South, and West regions of Sub-Saharan Africa. Cross-sectional time series data for 20 countries in 25 years are analyzed, and the results of the study show that wood fuel accounts for 70% of energy consumption, followed by petroleum, with most industrial activities utilizing some form of wood fuel. Regression results suggest that energy demand is inversely related to the price of petroleum and industrial development, but positively related to GDP, population growth rate, and agricultural expansion, and that price elasticity is less than one. The model results also show that there are regional differences in energy demand. In addition, the interaction of population growth rates by regions generates mixed results, and there are regional differences in the use of commercial energy consumption, and GDP growth. The findings of this study suggest that countries must diversify their energy sources and introduce energy-efficient devices and equipment at all levels of the economy to improve GDP growth rate and GDP per capita.

Full Text Available Africa belongs to important regions of the world economy with specific problems distinguishing this part of the world from other regions. The region is suffering because of limited economy structure and high level of poverty. Low economic performance ranks most of African countries among the worldwide poorest ones (both from the point of view of total economy performance and also individuals living standards; the development is hindered by political instability and also by other accompanied problems as high level of corruption, deficit of democracy, low level of education, limited investments, criminality, local conflicts, civil wars etc. On the other hand, African natural, economy and social resources and unexploited opportunities in many areas offer a potential for a considerable economic development. Understanding the current economic position of African states thus may reveal causes of problematic development and outline ways to overcome existing shortcomings. The aim of the paper is to analyze main changes in area of GDP structure formation (agricultural, industrial and services sector share in GDP and value performance which have occurred in selected African (Sub-Saharan countries. Changes are analyzed both in relation to the total GDP and GDP per capita. The authors identify main trends of economic development in the Sub-Saharan region and to specify differences among Sub-Saharan countries with the intention to identify particular groups of African countries according to their economic structure and to identify differences in their GDP formation.

Infrastructure and Other Considerations to Launch Nuclear Power Programme: The Case of Sub-Sahara African Developing Countries like Ethiopia

International Nuclear Information System (INIS)

Meshesha, Atnatiwos Zeleke

2011-01-01

Trends in the world's population and energy use during the past decades show dramatic increases; and the demand for electricity, mainly from developing countries, is expected to increase more rapidly than the demand for other forms of energy. Besides, concern of climate change led to the need for production of significant amount of 'safe and clean' energy which in turn favours to nuclear option. Other alternative renewable sources like solar and wind can assist but currently they are short of supplying the required high energy demand either economically or/and in substantial amount. Nuclear option therefore remains a possible (developed) technology to fill this energy gap; and many countries including developing one show interest to make use of this energy source. In this paper the economic situations and energy production of six East Africa Sub-Saharan developing countries, with total population of 240 million were assessed, and 6.8% and 2.9% average GDP and population growth respectively registered in the last four years; however, their energy production in 2008 (est.) was 17.662 billion kWh, which is the least in the world. The contribution of inadequate energy and its poor coverage in hampering development, increase poverty and unstability were also analyzed. To come out of this cyclic challenge; it is recommended that countries based on regional economic cooperation should interconnect their electricity grid like EAPP and cooperate to invest commonly or unilaterally to launch Nuclear Power Programmes in relatively stable countries. Candid support of the international community is crucial, and IAEA should support and encourage such arrangements. It is also noted that the best candidate to start NP programme in these countries would be the worldwide dominant water cooled reactors. However, for countries with low grid capacity and to carry out projects in remote areas which are far-away from national grid systems or to desalinate water, considerations for smaller

Antiretrovirals are available at low prices in sub-Saharan Africa, but these prices may not be consistently available for middle-income countries in other regions with large HIV epidemics. Over 30% of HIV infected people live in countries outside sub-Saharan Africa. Several key antiretrovirals are still on patent, with generic production restricted. We assessed price variations for key antiretroviral drugs inside versus outside sub-Saharan Africa. HIV drug prices used in national programmes (2010-2014) were extracted from the WHO Global Price Reporting Mechanism database for all reporting middle-income countries as classified by the World Bank. Treatment costs (branded and generic) were compared for countries inside sub-Saharan Africa versus those outside. Five key second-line antiretrovirals were analysed: abacavir, atazanavir, darunavir, lopinavir/ritonavir, raltegravir. Prices of branded antiretrovirals were significantly higher outside sub-Saharan Africa (psub-Saharan Africa versus $4689 (IQR $4075-5717) in non-African middle-income countries, an increase of 541%. However, when supplied by generic companies, most antiretrovirals were similarly priced between countries in sub-Saharan Africa and other regions. Pharmaceutical companies are selling antiretrovirals to non-African middle-income countries at prices 74-541% higher than African countries with similar gross national incomes. However, generic companies are selling most of these drugs at similar prices across regions. Mechanisms to ensure fair pricing for patented antiretrovirals across both African and non-African middle-income countries need to be improved, to ensure sustainable treatment access.

What drives energy consumption in developing countries? The experience of selected African countries

Keho, Yaya

2016-01-01

This study investigates the drivers of energy consumption in Sub-Saharan African countries. It applies the bounds testing approach to cointegration to time series data at individual country levels over the period from 1970 to 2011. The study finds that energy consumption is cointegrated with real GDP per capita, industrial output, imports, foreign direct investment, credit to private sector, urbanization and population. Furthermore, the sign and magnitude of long-run estimates vary significantly for a single country and across countries depending on the energy consumption variable used. Overall, the findings confirm the leading role of economic growth, industrial output, population and urbanization. Economic growth, industrial output and population have positive effects on energy consumption in the majority of countries. Given the urgent need to address climate change, African countries should adopt policies to improve energy efficiency and accelerate transition toward renewable energy. The African Renewable Energy Initiative launched at the 21st session of the United Nations Conference of the Parties (COP21) is an opportunity for African countries to provide and maintain widespread access to reliable and affordable environmentally cleaner energy to meet the requirements of rapid economic growth and improved living standards. - Highlights: •Key drivers of energy use in 12 African countries are examined. •Economic growth, industrial GDP, population and urbanization play a leading role in explaining energy use. •Urbanization has a positive effect on energy use in six countries and a negative effect in four countries. •The results obtained have useful policy implications.

Corruption in Sub-Saharan Africa: A practical-theological response

Full Text Available On the 2012 Corruption Perceptions Index of Transparency International, 89.6% of Sub-Saharan African countries received scores below 50, where a score of zero signifies that the country is highly corrupt and a score of 100 declares a country free of corruption. From these results, it seems as if Sub-Saharan African countries are quite vulnerable to corruption. In this article, the question whether certain traits in the Sub-Saharan African culture such as communalism, gift giving and a shame culture could in some situations influence people’s perception of, and their possible openness towards, certain forms of corruption was investigated. The research showed that cultural traits do influence people’s behaviour and that there are certain traits in the Sub-Saharan African culture that might sanction corruption. In response to these findings, some preliminary suggestions were proposed as to how Christians living in Africa could evaluate their cultural practices in the light of God’s Word and from a reformed theological paradigm. Instead of succumbing to the pressure posed by their culture to participate in immoral or corrupt activities, they could contribute to a moral regeneration on the African continent. Volgens Transparency International se 2012-CorruptionPerceptions Index het 89.6% van Afrikalande suid van die Sahara ’n telling van minder as 50 gekry, waar ’n telling van nul op hoë korrupsie dui en ’n telling van 100 aandui dat ’n land vry van korrupsie is. Hieruit blyk dat hierdie lande kwesbaar is vir korrupsie. In hierdie artikel word die moontlikheid ondersoek dat daar sekere eienskappe in die kultuur van hierdie lande is wat mense se persepsie van, en moontlike deelname aan, sekere vorme van korrupsie kan beïnvloed. Aandag word aan aspekte soos kommunalisme, die gee van geskenke en ’n ‘skandekultuur’ gegee. Die navorsing toon dat kultuur wel mense se gedrag beïnvloed en dat daar sekere eienskappe in die kultuur van

Global economic and financial crisis: Exploring the transmission channels and impacts on sub-saharan african economies

2016-12-01

Full Text Available Over the past decade sub-Saharan African countries have made remarkable gains in promoting growth alongside economic stability. However, with the outbreak of the financial and economic crisis in advanced economies, will these hard-won economic gains in the region be threatened? In this paper, we seek to provide an overview of how sub-Saharan African countries are exposed to the crisis through both financial and real transmission channels, and to critically assess the impact of the crisis on different economies. To accomplish this task, we first provide an overview of the recent economic development of sub-Saharan African countries, and a brief discussion of the sources and the development of the crisis. We then proceed to explore the direct financial transmission channels of the crisis and their impacts on sub-Saharan African countries. In addition, we explore the indirect real transmission channels of the crisis and how the sub-Saharan African economies are impacted by them. Thereafter, we identify a couple of policy implications

Full Text Available Abstract Background Most European countries are ethnically and culturally diverse. Globally, cardiovascular disease (CVD is the leading cause of death. The major risk factors for CVD have been well established. This picture holds true for all regions of the world and in different ethnic groups. However, the prevalence of CVD and related risk factors vary among ethnic groups. Methods This article provides a review of current understanding of the epidemiology of vascular disease, principally coronary heart disease (CHD, stroke and related risk factors among populations of Sub-Sahara African descent (henceforth, African descent in comparison with the European populations in Europe. Results Compared with European populations, populations of African descent have an increased risk of stroke, whereas CHD is less common. They also have higher rates of hypertension and diabetes than European populations. Obesity is highly prevalent, but smoking rate is lower among African descent women. Older people of African descent have more favourable lipid profile and dietary habits than their European counterparts. Alcohol consumption is less common among populations of African descent. The rate of physical activity differs between European countries. Dutch African-Suriname men and women are less physically active than the White-Dutch whereas British African women are more physically active than women in the general population. Literature on psychosocial stress shows inconsistent results. Conclusion Hypertension and diabetes are highly prevalent among African populations, which may explain their high rate of stroke in Europe. The relatively low rate of CHD may be explained by the low rates of other risk factors including a more favourable lipid profile and the low prevalence of smoking. The risk factors are changing, and on the whole, getting worse especially among African women. Cohort studies and clinical trials are therefore needed among these groups to

Full Text Available Abstract There is an ongoing global movement for the entrenchment of occupational mental health as an integral part of occupational health and safety schemes. Aside from being a fundamental human right issue, this move has been demonstrated to be of cost-benefit in terms of workplace productivity and general economic growth. Despite being among the regions most prone to the human and economic repercussions of work-related mental health problems by reason of her socio-economic circumstance; sub-Sahara Africa is yet to fully plug into this movement. With a view to make recommendations on the ways forward for sub-Sahara Africa, this paper examines the current state of and the barriers to effective occupational mental health policy and practice in the region.

2011-11-01

In recent years, governments of several low-income countries have taken decisive action by removing fully or partially user fees in the health sector. In this study, we review recent reforms in six sub-Saharan African countries: Burkina Faso, Burundi, Ghana, Liberia, Senegal and Uganda. The review describes the processes and strategies through which user fee removal reforms have been implemented and tries to assess them by referring to a good practice hypotheses framework. The analysis shows that African leaders are willing to take strong action to remove financial barriers met by vulnerable groups, especially pregnant women and children. However, due to a lack of consultation and the often unexpected timing of the decision taken by the political authorities, there was insufficient preparation for user fee removal in several countries. This lack of preparation resulted in poor design of the reform and weaknesses in the processes of policy formulation and implementation. Our assessment is that there is now a window of opportunity in many African countries for policy action to address barriers to accessing health care. Mobilizing sufficient financial resources and obtaining long-term commitment are obviously crucial requirements, but design details, the formulation process and implementation plan also need careful thought. We contend that national policy-makers and international agencies could better collaborate in this respect.

Trends and challenges toward integration of traditional medicine in formal health-care system: Historical perspectives and appraisal of education curricula in Sub-Sahara Africa

Innocent, Ester

2016-01-01

The population residing Sub-Sahara Africa (SSA) continues to suffer from communicable health problems such as HIV/AIDS, malaria, tuberculosis, and various neglected tropical as well as non-communicable diseases. The disease burden is aggravated by shortage of medical personnel and medical supplies such as medical devices and minimal access to essential medicine. For long time, human beings through observation and practical experiences learned to use different plant species that led to the emergence of traditional medicine (TM) systems. The ancient Pharaonic Egyptian TM system is one of the oldest documented forms of TM practice in Africa and the pioneer of world’s medical science. However, the medical practices diffused very fast to other continents being accelerated by advancement of technologies while leaving Africa lagging behind in the integration of the practice in formal health-care system. Challenging issues that drag back integration is the development of education curricula for training TM experts as the way of disseminating the traditional medical knowledge and practices imbedded in African culture. The few African countries such as Ghana managed to integrate TM products in the National Essential Medicine List while South Africa, Sierra Leone, and Tanzania have TM products being sold over the counters due to the availability of education training programs facilitated by research. This paper analyses the contribution of TM practice and products in modern medicine and gives recommendations that Africa should take in the integration process to safeguard the SSA population from disease burdens.

Full Text Available Forests contribute immensely to economic and social development through formal trade in timber environmental services non- timber forest products safety net spiritual and aesthetic value. Wood is a key source of energy that has been used for millennia for cooking boiling water lighting and heating. Today about 2.5billion people depend on biomass energy for cooking and heating with 87 of this energy being provided by wood. In sub-Saharan African more than 90 of the population relies on wood fire that is firewood and charcoal as their primary source of domestic energy. Over 80 of urban householders and small industries use charcoal and firewood as their source of energy. Despite their numerous importance Africas forest continue to decline rapidly due to increase in agricultural practices into forest lands population growth and urbanization increased poverty high dependence on natural resources for subsistence and income through forest. The study centred on the implications of fuel wood demand on forest conservation in sub-Sahara Africa - a regional focus on Akure metropolitan area Ondo State. The specific objectives of the paper were to identify firewood consumption pattern in Akure metropolitan area and factors responsible for increased fuelwood demand in the study area. The paper adopted direct observation oral interview and 0.05 of the study area as sample size for the study. The study observed lack of adequate alternative poor implementation and enforcement of government regulation on forestry poverty and poor awareness on the menace of forest depletion among others. The paper posited provision of alternative fuel with subsidy regular awareness campaign proper monitoring implementation and enforcement of forest regulations with a view to achieving sustainable conservation.

Aridification of the Sahara desert caused by Tethys Sea shrinkage during Late Miocene

Science.gov (United States)

Zhang, Z.; Ramstein, G.; Schuster, M.; Li, C.; Contoux, C.; Yan, Q.

2014-12-01

It is widely believed that the Sahara desert is no more than ~2-3 million years (Myr) old, with geological evidence showing a remarkable aridification of north Africa at the onset of the Quaternary ice ages. Before that time, north African aridity was mainly controlled by the African summer monsoon (ASM), which oscillated with Earth's orbital precession cycles. Afterwards, the Northern Hemisphere glaciation added an ice volume forcing on the ASM, which additionally oscillated with glacial-interglacial cycles. These findings led to the idea that the Sahara desert came into existence when the Northern Hemisphere glaciated ~2-3 Myr ago. The later discovery, however, of aeolian dune deposits ~7 Myr old suggested a much older age, although this interpretation is hotly challenged and there is no clear mechanism for aridification around this time. Here we use climate model simulations to identify the Tortonian stage (~7-11 Myr ago) of the Late Miocene epoch as the pivotal period for triggering north African aridity and creating the Sahara desert. Through a set of experiments with the Norwegian Earth System Model and the Community Atmosphere Model, we demonstrate that the African summer monsoon was drastically weakened by the Tethys Sea shrinkage during the Tortonian, allowing arid, desert conditions to expand across north Africa. Not only did the Tethys shrinkage alter the mean climate of the region, it also enhanced the sensitivity of the African monsoon to orbital forcing, which subsequently became the major driver of Sahara extent fluctuations. These important climatic changes probably caused the shifts in Asian and African flora and fauna observed during the same period, with possible links to the emergence of early hominins in north Africa.

Speleothem evidence for the greening of the Sahara and its implications for the early human dispersal out of sub-Saharan Africa

Although there is a consensus that there were wet periods (greening events) in the Sahara in the past, the spatial extent and the timing of these greening events are still in dispute, yet critical to our understanding of the early human dispersal out of Africa. Our U-series dates of speleothems from the Northeastern Sahara (Wadi Sannur cave, Egypt) reveal that the periods of speleothem growth were brief and restricted to the interglacial Marine Isotope Stages MIS 5.5, MIS 7.3, and the early MIS 9 with a remarkable absence of the Holocene deposition of speleothems. These growth periods of Wadi Sannur cave speleothems correspond to periods of high rainfall and spread of vegetation (green Sahara). Distinct low δ18O values of speleothems indicate a distal moisture source that we interpret to be the Atlantic Ocean. These two lines of evidence from the Wadi Sannur speleothems thus suggest that maximal northward shifts in the West African monsoon system occurred during the growth periods of the speleothems, leading to greening of the Sahara, facilitating human migration into Eurasia. The periods of speleothem growth at Wadi Sannur cave are contemporaneous with important archeological events: (1) the earliest occurrence of the Middle Stone Age assemblages and Homo sapiens in North Africa (Jebel Irhoud), suggesting wide spread of greening conditions over the East-West transect of the Sahara, (2) the sharp technological break between the Acheulo-Yabrudian and the Mousterian industries, and (3) the arrival of Homo sapiens in Levant, indicating a key role of the Sahara route in early human dispersal out of Africa.

Migrant health workers fill care gaps in their destination countries, but they also actively engage in improving living conditions for people of their countries of origin through expatriate professional networks. This paper aims to explore the professional links that migrant health workers from sub-Saharan African countries living in five African and European destinations (Botswana, South Africa, Belgium, Austria, and the United Kingdom) have to their countries of origin. Qualitative interviews were conducted with migrant doctors, nurses, and midwives from sub-Saharan Africa (N=66). A qualitative content analysis of the material was performed using the software ATLAS.ti. Almost all migrant health workers have professional ties with their countries of origin supporting health, education, and social structures. They work with non-governmental organizations, universities, or hospitals and travel back and forth between their destination country and country of origin. For a few respondents, professional engagement or even maintaining private contacts in their country of origin is difficult due to the political situation at home. The results show that African migrant health workers are actively engaged in improving living conditions not only for their family members but also for the population in general in their countries of origin. Our respondents are mediators and active networkers in a globalized and transnationally connected world. The research suggests that the governments of these countries of origin could strategically use their migrant health workforce for improving education and population health in sub-Saharan Africa. Destination countries should be reminded of their need to comply with the WHO Global Code of Practice for the international recruitment of health professionals.

Effective coverage and systems effectiveness for malaria case management in sub-Saharan African countries.

Directory of Open Access Journals (Sweden)

Katya Galactionova

Full Text Available Scale-up of malaria preventive and control interventions over the last decade resulted in substantial declines in mortality and morbidity from the disease in sub-Saharan Africa and many other parts of the world. Sustaining these gains will depend on the health system performance. Treatment provides individual benefits by curing infection and preventing progression to severe disease as well as community-level benefits by reducing the infectious reservoir and averting emergence and spread of drug resistance. However many patients with malaria do not access care, providers do not comply with treatment guidelines, and hence, patients do not necessarily receive the correct regimen. Even when the correct regimen is administered some patients will not adhere and others will be treated with counterfeit or substandard medication leading to treatment failures and spread of drug resistance. We apply systems effectiveness concepts that explicitly consider implications of health system factors such as treatment seeking, provider compliance, adherence, and quality of medication to estimate treatment outcomes for malaria case management. We compile data for these indicators to derive estimates of effective coverage for 43 high-burden Sub-Saharan African countries. Parameters are populated from the Demographic and Health Surveys and other published sources. We assess the relative importance of these factors on the level of effective coverage and consider variation in these health systems indicators across countries. Our findings suggest that effective coverage for malaria case management ranges from 8% to 72% in the region. Different factors account for health system inefficiencies in different countries. Significant losses in effectiveness of treatment are estimated in all countries. The patterns of inter-country variation suggest that these are system failures that are amenable to change. Identifying the reasons for the poor health system performance and

The need to decompose CO 2 emission intensity is predicated upon the need for effective climate change mitigation and adaptation policies. Such analysis enables key variables that instigate CO 2 emission intensity to be identified while at the same time providing opportunities to verify the mitigation and adaptation capacities of countries. However, most CO 2 decomposition analysis has been conducted for the developed economies and little attention has been paid to sub-Saharan Africa. The need for such an analysis for SSA is overwhelming for several reasons. Firstly, the region is amongst the most vulnerable to climate change. Secondly, there are disparities in the amount and composition of energy consumption and the levels of economic growth and development in the region. Thus, a decomposition analysis of CO 2 emission intensity for SSA affords the opportunity to identify key influencing variables and to see how they compare among countries in the region. Also, attempts have been made to distinguish between oil and non-oil-producing SSA countries. To this effect a comparative static analysis of CO 2 emission intensity for oil-producing and non oil-producing SSA countries for the periods 1971-1998 has been undertaken, using the refined Laspeyres decomposition model. Our analysis confirms the findings for other regions that CO 2 emission intensity is attributable to energy consumption intensity, CO 2 emission coefficient of energy types and economic structure. Particularly, CO 2 emission coefficient of energy use was found to exercise the most influence on CO 2 emission intensity for both oil and non-oil-producing sub-Saharan African countries in the first sub-interval period of our investigation from 1971-1981. In the second subinterval of 1981-1991, energy intensity and structural effect were the two major influencing factors on emission intensity for the two groups of countries. However, energy intensity effect had the most pronounced impact on CO 2 emission

Aridification of the Sahara desert caused by Tethys Sea shrinkage during the Late Miocene

Science.gov (United States)

2014-09-01

It is widely believed that the Sahara desert is no more than ~2-3 million years (Myr) old, with geological evidence showing a remarkable aridification of north Africa at the onset of the Quaternary ice ages. Before that time, north African aridity was mainly controlled by the African summer monsoon (ASM), which oscillated with Earth's orbital precession cycles. Afterwards, the Northern Hemisphere glaciation added an ice volume forcing on the ASM, which additionally oscillated with glacial-interglacial cycles. These findings led to the idea that the Sahara desert came into existence when the Northern Hemisphere glaciated ~2-3 Myr ago. The later discovery, however, of aeolian dune deposits ~7 Myr old suggested a much older age, although this interpretation is hotly challenged and there is no clear mechanism for aridification around this time. Here we use climate model simulations to identify the Tortonian stage (~7-11 Myr ago) of the Late Miocene epoch as the pivotal period for triggering north African aridity and creating the Sahara desert. Through a set of experiments with the Norwegian Earth System Model and the Community Atmosphere Model, we demonstrate that the African summer monsoon was drastically weakened by the Tethys Sea shrinkage during the Tortonian, allowing arid, desert conditions to expand across north Africa. Not only did the Tethys shrinkage alter the mean climate of the region, it also enhanced the sensitivity of the African monsoon to orbital forcing, which subsequently became the major driver of Sahara extent fluctuations. These important climatic changes probably caused the shifts in Asian and African flora and fauna observed during the same period, with possible links to the emergence of early hominins in north Africa.

Maternity health care: The experiences of Sub-Saharan African women in Sub-Saharan Africa and Australia.

Mohale, Hlengiwe; Sweet, Linda; Graham, Kristen

2017-08-01

Increasing global migration is resulting in a culturally diverse population in the receiving countries. In Australia, it is estimated that at least four thousand Sub-Saharan African women give birth each year. To respond appropriately to the needs of these women, it is important to understand their experiences of maternity care. The study aimed to examine the maternity experiences of Sub-Saharan African women who had given birth in both Sub-Saharan Africa and in Australia. Using a qualitative approach, 14 semi-structured interviews with Sub-Saharan African women now living in Australia were conducted. Data was analysed using Braun and Clark's approach to thematic analysis. Four themes were identified; access to services including health education; birth environment and support; pain management; and perceptions of care. The participants experienced issues with access to maternity care whether they were located in Sub-Saharan Africa or Australia. The study draws on an existing conceptual framework on access to care to discuss the findings on how these women experienced maternity care. The study provides an understanding of Sub-Saharan African women's experiences of maternity care across countries. The findings indicate that these women have maternity health needs shaped by their sociocultural norms and beliefs related to pregnancy and childbirth. It is therefore arguable that enhancing maternity care can be achieved by improving women's health literacy through health education, having an affordable health care system, providing respectful and high quality midwifery care, using effective communication, and showing cultural sensitivity including family support for labouring women.

A Bayesian analysis of the impact of post-crash care on road mortality in Sub-Saharan African countries

2017-10-01

Full Text Available Sub-Saharan Africa is undergoing a disproportionate road tragedy compared to its motorization rate and road network density. Most of the road traffic deaths occur in the pre-hospital phase. Yet, more than half of the African countries do not possess formal pre-hospital care system. This study assesses the potential impact of post-crash care on road mortality in 23 Sub-Saharan African countries. A panel Bayesian normal linear regression with normally distributed non-informative priors is used to fit the data set covering the time period 2001–2010. The post-crash care system is proxied by the estimated share of seriously injured transported by ambulance, and three binary variables indicating the existence of emergency access telephone services and emergency training for doctors and nurses. The findings suggest a negative correlation between the road mortality rate and the estimated share of seriously injured transported by ambulance, the emergency access telephone services and the emergency training for doctors. A positive relation is unexpectedly observed for the emergency training for nurses. Other regressors such as the Gross Domestic Product per capita and populations in the age range 15–64 years are related to higher fatality rates while the length of the road network and life expectancy are linked to decreasing fatality rates.

Timing of maternal death: Levels, trends, and ecological correlates using sibling data from 34 sub-Saharan African countries.

Full Text Available Millennium Development Goal 5 has not been universally achieved, particularly in sub-Saharan Africa. Understanding whether maternal deaths occur during pregnancy, childbirth, or puerperium is important to effectively plan maternal health programs and allocate resources. Our main research objectives are to (1 describe the proportions and rates of mortality for the antepartum, intrapartum, and postpartum periods; (2 document how these trends vary by sub-region; and (3 investigate ecological correlations between these rates and maternal care interventions. We used data from the Demographic and Health Survey program, which comprises 84 surveys from 34 sub-Saharan African countries conducted between 1990 and 2014. We calculated age-standardized maternal mortality rates and time-specific maternal mortality rates and proportions, and we assessed correlations with maternal care coverage. We found high levels of maternal mortality in all three periods. Time-specific maternal mortality rates varied by country and region, with some showing an orderly decline in all three periods and others exhibiting alarming increases in antepartum and postpartum mortality. Ecological analysis showed that antenatal care coverage was significantly associated with low antepartum mortality, whereas the presence of a skilled attendant at childbirth was significantly associated with low postpartum mortality. In sub-Saharan Africa, maternal deaths occur at high rates in all three risk periods, and vary substantially by country and region. The provision of maternal care is a predictor of time-specific maternal mortality. These results confirm the need for country-specific interventions during the continuum of care to achieve the global commitment to eliminating preventable maternal mortality.

2018-06-01

Afforestation of the Sahara has been proposed as a climate engineering method to sequester a substantial amount of carbon dioxide, potentially effective to mitigate climate change. Earlier studies predicted changes in the atmospheric circulation system. These atmospheric feedbacks raise questions about the self-sustainability of such an intervention, but have not been investigated in detail. Here, we investigate changes in precipitation and circulation in response to Saharan large-scale afforestation and irrigation with NCAR's CESM-WACCM Earth system model. Our model results show a Saharan temperature reduction by 6 K and weak precipitation enhancement by 267 mm/year over the Sahara. Only 26% of the evapotranspirated water re-precipitates over the Saharan Desert, considerably large amounts are advected southward to the Sahel zone and enhance the West African monsoon (WAM). Different processes cause circulation and precipitation changes over North Africa. The increase in atmospheric moisture leads to radiative cooling above the Sahara and increased high-level cloud coverage as well as atmospheric warming above the Sahel zone. Both lead to a circulation anomaly with descending air over the Sahara and ascending air over the Sahel zone. Together with changes in the meridional temperature gradient, this results in a southward shift of the inner-tropical front. The strengthening of the Tropical easterly jet and the northward displacement of the African easterly jet is associated with a northward displacement and strengthening of the WAM precipitation. Our results suggest complex atmospheric circulation feedbacks, which reduce the precipitation potential over an afforested Sahara and enhance WAM precipitation.

Many studies have investigated the migration intentions of sub-Saharan African medical students and health professionals within the context of a legacy of active international recruitment by receiving countries. However, many health workers migrate outside of this recruitment paradigm. This paper aims to explore the reasons for migration of health workers from sub-Saharan Africa to Belgium and Austria; European countries without a history of active recruitment in sub-Saharan Africa. Data were collected using semistructured interviews. Twenty-seven health workers were interviewed about their migration experiences. Included participants were born in sub-Saharan Africa, had trained as health workers in sub-Saharan Africa, and were currently living in Belgium or Austria, though not necessarily currently working as a health professional. Both Austria and Belgium were shown not to be target countries for the health workers, who instead moved there by circumstance, rather than choice. Three principal reasons for migration were reported: 1) educational purposes; 2) political instability or insecurity in their country of origin; and 3) family reunification. In addition, two respondents mentioned medical reasons and, although less explicit, economic factors were also involved in several of the respondents' decision to migrate. These results highlight the importance of the broader economic, social, and political context within which migration decisions are made. Training opportunities proved to be an important factor for migration. A further development and upgrade of primary care might help to counter the common desire to specialize and improve domestic training opportunities.

Five databases, Medline, Embase, Africa-wide Information, Cinahl Plus, and Global Health were searched using a systematic search strategy. There were no language restrictions. 26 included studies measured current smoking prevalence in nationally representative adult populations in sub-Saharan African countries. Study details were independently extracted using a standard datasheet. Data on tobacco control policies, taxation and trends in prices were obtained from the Implementation Database of the WHO FCTC website. Studies represented 13 countries. Current smoking prevalence varied widely ranging from 1.8% in Zambia to 25.8% in Sierra Leone. The prevalence of smoking was consistently lower in women compared to men with the widest gender difference observed in Malawi (men 25.9%, women 2.9%). Rwanda had the highest prevalence of women smokers (12.6%) and Ghana had the lowest (0.2%). Rural, urban patterns were inconsistent. Most countries have implemented demand-reduction measures including bans on advertising, and taxation rates but to different extents. Smoking prevalence varied widely across sub-Saharan Africa, even between similar country regions, but was always higher in men. High smoking rates were observed among countries in the eastern and southern regions of Africa, mainly among men in Ethiopia, Malawi, Rwanda, and Zambia and women in Rwanda and rural Zambia. Effective action to reduce smoking across sub-Saharan Africa, particularly targeting population groups at increased risk remains a pressing public health priority.

Long-distance autumn migration across the Sahara by painted lady butterflies: exploiting resource pulses in the tropical savannah.

Stefanescu, Constantí; Soto, David X; Talavera, Gerard; Vila, Roger; Hobson, Keith A

2016-10-01

The painted lady, Vanessa cardui, is a migratory butterfly that performs an annual multi-generational migration between Europe and North Africa. Its seasonal appearance south of the Sahara in autumn is well known and has led to the suggestion that it results from extremely long migratory flights by European butterflies to seasonally exploit the Sahel and the tropical savannah. However, this possibility has remained unproven. Here, we analyse the isotopic composition of butterflies from seven European and seven African countries to provide new support for this hypothesis. Each individual was assigned a geographical natal origin, based on its wing stable hydrogen isotope (δ 2 H w ) value and a predicted δ 2 H w basemap for Europe and northern Africa. Natal assignments of autumn migrants collected south of the Sahara confirmed long-distance movements (of 4000 km or more) starting in Europe. Samples from Maghreb revealed a mixed origin of migrants, with most individuals with a European origin, but others having originated in the Sahel. Therefore, autumn movements are not only directed to northwestern Africa, but also include southward and northward flights across the Sahara. Through this remarkable behaviour, the productive but highly seasonal region south of the Sahara is incorporated into the migratory circuit of V. cardui. © 2016 The Author(s).

Angola - an Oil Dependant Country in Sub-Saharan Africa

Full Text Available The Sub-Saharan Africa belongs to the most underdeveloped regions in the world economy. This region consists of forty nine countries but it’s world GDP share is only a small percentage. There are some very resource rich countries in this region. One of them is Angola. This former Portuguese colony has one of the largest inventories of oil among all African countries. Angola recorded one of the highest growth of GDP between 2004-2008 from all countries in the world economy and nowadays is the third biggest economy in Sub-Saharan Africa after Nigeria and South Africa. The essential problem of Angola is the one-way oriented economy on oil and general on natural resources. Angola will be forced to change their one-way oriented economy to be more diversified and competitive in the future.

Spain and the Western Sahara: the Political Party Dimension

Directory of Open Access Journals (Sweden)

Jordi Vaquer i Fanés

2007-12-01

Full Text Available Since the Spanish army’s hasty withdrawal from Western Sahara in 1975, the two main parties since Spain acquired its democracy have differed over what stance should be taken with respect to the Sahara issue. The aim of this article is to establish to what extentthis is the result of the opposing government/opposition dynamic and how far it is a result of the parties’ own stances, by analysing the evolution of their attitudes and approaches with respect to the Sahara issue. The hypothesis is that the Spanish parties’ position with respect to Algeria and Morocco was initially very much determined by their view of the Sahara issue, but that there has been an inversion of this attitude. Thus at present, opposing stances on the Sahara issue are mainly the result of different views on Spain’s interests in the Maghreb region and, above all, of different ideas about which country Morocco or Algeria should benefit most from bilateral relations.

Morocco has experienced a dramatic increase of migration from sub-Sahara Africa during the past decade. Recently included among the most vulnerable populations cited in the Morocco National Strategic Plans on HIV/TB for 2012-2016, sub-Saharan Africa migrants living in an irregular administrative situation participated in a survey to provide baseline data about their socio-demographic, sexual and HIV testing behaviors and HIV and syphilis prevalence. Two surveys using respondent driven sampling were conducted in 2013 among males and females, ≥18 years, originating from sub-Saharan African countries and living and/or working in an irregular administrative situation in Rabat and residing at least 3 months in Morocco. Analysis was conducted to evaluate differences between the two samples and between females and males within each sample using the successive sampling estimator in RDS Analyst. Roughly 3 % of francophone and anglophone migrants were infected with HIV, whereas a statistically significantly higher percentage of francophone (2.8 %), compared to anglophone (0.3 %), migrants were infected with syphilis. Females were found to have HIV infection rates three times higher and past year sexually transmitted infection signs and symptoms more than two times higher than their male counterparts. Female migrants also had statistically significantly higher percentages of ever testing for HIV and HIV testing and receiving results in the past year compared to males. We found distinct and important differences between migrants depending on whether they come from francophone versus anglophone countries and whether they were male or female. Future research should continue to explore these differences, while policies and programs should note these differences to best allocate resources in providing social and health services to these populations.

Sub-Saharan Africa suffers a disproportionate share of the world's burden of disease while having some of the world's greatest health care workforce shortages. Doctors are an important component of any high functioning health care system. However, efforts to strengthen the doctor workforce in the region have been limited by a small number of medical schools with limited enrolments, international migration of graduates, poor geographic distribution of doctors, and insufficient data on medical schools. The goal of the Sub-Saharan African Medical Schools Study (SAMSS) is to increase the level of understanding and expand the baseline data on medical schools in the region. The SAMSS survey is a descriptive survey study of Sub-Saharan African medical schools. The survey instrument included quantitative and qualitative questions focused on institutional characteristics, student profiles, curricula, post-graduate medical education, teaching staff, resources, barriers to capacity expansion, educational innovations, and external relationships with government and non-governmental organizations. Surveys were sent via e-mail to medical school deans or officials designated by the dean. Analysis is both descriptive and multivariable. Surveys were distributed to 146 medical schools in 40 of 48 Sub-Saharan African countries. One hundred and five responses were received (72% response rate). An additional 23 schools were identified after the close of the survey period. Fifty-eight respondents have been founded since 1990, including 22 private schools.

Objectives In many sub-Saharan African countries, the use of long-acting reversible contraceptives (LARCs) is low while unmet need for family planning (FP) remains high. We evaluated the effectiveness of a LARC access expansion initiative in reaching young, less educated, poor, and rural women. Methods Starting in 2008, Marie Stopes International (MSI) has implemented a cross-country expansion intervention to increase access to LARCs through static clinics, mobile outreach units, and social franchising of private sector providers. We analyzed routine service statistics for 2008-2014 and 2014 client exit interview data. Indicators of effectiveness were the number of LARCs provided and the percentages of LARC clients who had not used a modern contraceptive in the last 3 months ("adopters"); switched from a short-term contraceptive to a LARC ("switchers"); were aged <25; lived in extreme poverty; had not completed primary school; lived in rural areas; and reported satisfaction with their overall experience at the facility/site. Results Our annual LARC service distribution increased 1037 % (from 149,881 to over 1.7 million) over 2008-2014. Of 3816 LARC clients interviewed, 46 % were adopters and 46 % switchers; 37 % were aged 15-24, 42 % had not completed primary education, and 56 % lived in a rural location. Satisfaction with services received was rated 4.46 out of 5. Conclusions The effectiveness of the LARC expansion in these 14 sub-Saharan African FP programs demonstrates vast untapped potential for wider use of LARC methods, and suggests that this service delivery model is a plausible way to support FP 2020 goals of reaching those with an unmet need for FP.

African leaders accepted in the year 2001 through the Abuja Declaration to allocate 15% of their government expenditure on health but by 2013 only five (5) African countries achieved this target. In this paper, a comparative analysis on the impact of health expenditure between countries in the CEMAC sub-region and five other African countries that achieved the Abuja declaration is provided. Data for this study was extracted from the World Development Indicators (2016) database, panel ordinary least square (OLS), fully modified ordinary least square (FMOLS) and dynamic ordinary least square (DOLS) were used as econometric technic of analysis. Results showed that health expenditure has a positive and significant effect on economic growth in both samples. A unit change in health expenditure can potentially increase GDP per capita by 0.38 and 0.3 units for the five other African countries that achieve the Abuja target and for CEMAC countries respectively, a significant difference of 0.08 units among the two samples. In addition, a long-run relationship also exist between health expenditure and economic growth for both groups of countries. Thus African Economies are strongly advised to achieve the Abuja target especially when other socio-economic and political factors are efficient.

Full Text Available Substantial amount of studies have examined the validity of mean-reversion onthe real exchange rate. However very limited studies of this nature have beenconducted in Sub-Saharan Africa countries, particularly energy exportingcountries, hence this study endeavors to find evidence for or against the mean-reversion of the real exchange rate. There is, however inadequate data requiredfor the statistical significance for Sub-Saharan African currencies. Hence thisstudy uses a panel of 5 energy exporting countries, i.e. South Africa,Mozambique, Congo Republic, Nigeria and Angola, to examine the validity of thepurchasing power parity. Relying on the Im, Pesaran and Shin and the Fisher ADFproposed panel unit root tests the study fails to reject the null hypothesis of a unitroot when small sample size is employed however by extending sample size andemploying different price index, i.e. traded goods prices instead of GDP deflatorsthe study reject the null hypothesis of a unit root and hence concludes thepurchasing power parity holds in Sub-Saharan African energy exporting countriesconsidered in the study.

Schistosomiasis, a neglected tropical disease of poverty ranks second among the most widespread parasitic disease in various nations in sub-Saharan Africa. Neglected tropical diseases are causes of about 534,000 deaths annually in sub-Saharan Africa and an estimated 57 million disability-adjusted life-years are lost annually due to the neglected tropical diseases. The neglected tropical diseases exert great health, social and financial burden on economies of households and governments. Schistosomiasis has profound negative effects on child development, outcome of pregnancy, and agricultural productivity, thus a key reason why the "bottom 500 million" inhabitants of sub-Saharan Africa continue to live in poverty. In 2008, 17.5 million people were treated globally for schistosomiasis, 11.7 million of those treated were from sub-Saharan Africa. This enervating disease has been successfully eradicated in Japan, as well as in Tunisia. Morocco and some Caribbean Island countries have made significant progress on control and management of this disease. Brazil, China and Egypt are taking steps towards elimination of the disease, while most sub-Saharan countries are still groaning under the burden of the disease. Various factors are responsible for the continuous and persistent transmission of schistosomiasis in sub-Saharan Africa. These include climatic changes and global warming, proximity to water bodies, irrigation and dam construction as well as socio-economic factors such as occupational activities and poverty. The morbidity and mortality caused by this disease cannot be overemphasized. This review is an exposition of human schistosomiasis as it affects the inhabitants of various communities in sub-Sahara African countries. It is hoped this will bring a re-awakening towards efforts to combat this impoverishing disease in terms of vaccines development, alternative drug design, as well as new point-of-care diagnostics.

2012-07-01

Full Text Available Abstract Background The burden of fevers remains enormous in sub-Saharan Africa. While several efforts at reducing the burden of fevers have been made at the macro level, the relationship between socioeconomic status and fever prevalence has been inconclusive at the household and individual levels. The purpose of this study was to examine how individual and household socioeconomic status influences the prevalence of fever among children under age five in four sub-Saharan African countries. Methods The study used data from the 2008 Demographic and Health Survey (DHS from Ghana, Nigeria, Kenya and Sierra Leone with a total of 38,990 children below age five. A multi-level random effects logistic model was fitted to examine the socioeconomic factors that influence the prevalence of fever in the two weeks preceding the survey. Data from the four countries were also combined to estimate this relationship, after country-specific analysis. Results The results show that children from wealthier households reported lower prevalence of fever in Ghana, Nigeria and Kenya. Result from the combined dataset shows that children from wealthier households were less likely to report fever. In general, vaccination against fever-related diseases and the use of improved toilet facility reduces fever prevalence. The use of bed nets by children and mothers did not show consistent relationship across the countries. Conclusion Poverty does not only influence prevalence of fever at the macro level as shown in other studies but also the individual and household levels. Policies directed towards preventing childhood fevers should take a close account of issues of poverty alleviation. There is also the need to ensure that prevention and treatment mechanisms directed towards fever related diseases (such as malaria, pneumonia, measles, diarrhoea, polio, tuberculosis etc. are accessible and effectively used.

Socioeconomic inequalities in HIV/AIDS prevalence in sub-Saharan African countries: evidence from the Demographic Health Surveys

Science.gov (United States)

2014-01-01

Introduction Extant studies universally document a positive gradient between socioeconomic status (SES) and health. A notable exception is the apparent concentration of HIV/AIDS among wealthier individuals. This paper uses data from the Demographic Health Surveys and AIDS Indicator Surveys to examine socioeconomic inequalities in HIV/AIDS prevalence in 24 sub-Saharan African (SSA) countries, the region that accounts for two-thirds of the global HIV/AIDS burden. Methods The relative and generalized concentration indices (RC and GC) were used to quantify wealth-based socioeconomic inequalities in HIV/AIDS prevalence for the total adult population (aged 15-49), for men and women, and in urban and rural areas in each country. Further, we decomposed the RC and GC indices to identify the determinants of socioeconomic inequalities in HIV/AIDS prevalence in each country. Results Our findings demonstrated that HIV/AIDS was concentrated among higher SES individuals in the majority of SSA countries. Swaziland and Senegal were the only countries in the region where HIV/AIDS was concentrated among individuals living in poorer households. Stratified analyses by gender showed HIV/AIDS was generally concentrated among wealthier men and women. In some countries, including Kenya, Lesotho Uganda, and Zambia, HIV/AIDS was concentrated among the poor in urban areas but among wealthier adults in rural areas. Decomposition analyses indicated that, besides wealth itself (median = 49%, interquartile range [IQR] = 90%), urban residence (median = 54%, IQR = 81%) was the most important factor contributing to the concentration of HIV/AIDS among wealthier participants in SSA countries. Conclusions Further work is needed to understand the mechanisms explaining the concentration of HIV/AIDS among wealthier individuals and urban residents in SSA. Higher prevalence of HIV/AIDS could be indicative of better care and survival among wealthier individuals and urban adults, or reflect

The Ethics of Introducing GMOs into sub-Saharan Africa: Considerations from the sub-Saharan African Theory of Ubuntu.

Science.gov (United States)

Komparic, Ana

2015-11-01

A growing number of countries in sub-Saharan Africa are considering legalizing the growth of genetically modified organisms (GMOs). Furthermore, several projects are underway to develop transgenic crops tailored to the region. Given the contentious nature of GMOs and prevalent anti-GMO sentiments in Africa, a robust ethical analysis examining the concerns arising from the development, adoption, and regulation of GMOs in sub-Saharan Africa is warranted. To date, ethical analyses of GMOs in the global context have drawn predominantly on Western philosophy, dealing with Africa primarily on a material level. Yet, a growing number of scholars are articulating and engaging with ethical theories that draw upon sub-Saharan African value systems. One such theory, Ubuntu, is a well-studied sub-Saharan African communitarian morality. I propose that a robust ethical analysis of Africa's agricultural future necessitates engaging with African moral theory. I articulate how Ubuntu may lead to a novel and constructive understanding of the ethical considerations for introducing GMOs into sub-Saharan Africa. However, rather than reaching a definitive prescription, which would require significant engagement with local communities, I consider some of Ubuntu's broader implications for conceptualizing risk and engaging with local communities when evaluating GMOs. I conclude by reflecting on the implications of using local moral theory in bioethics by considering how one might negotiate between universalism and particularism in the global context. Rather than advocating for a form of ethical relativism, I suggest that local moral theories shed light on salient ethical considerations that are otherwise overlooked. © 2015 John Wiley & Sons Ltd.

Price elasticity of petroleum products in selected African countries

Kaul, S.

1995-01-01

In this paper, a fundamental understanding of the economic impact which is directly related to the price elasticity of petroleum products in six selected African countries is obtained by using the Jorgorson-Lian model for shares. Each kind of fuel price has a different impact on the share of oil products for the different countries. The price increase of one kind of fuel may increase or decrease the share of another fuel in the total oil products. In the oil importing African countries, the price of one product is relatively inelastic, whereas in the oil producing African countries, the price is elastic. (Author)

Antenatal syphilis screening using point-of-care testing in Sub-Saharan African countries: a cost-effectiveness analysis.

2013-11-01

Full Text Available Untreated syphilis in pregnancy is associated with adverse clinical outcomes for the infant. Most syphilis infections occur in sub-Saharan Africa (SSA, where coverage of antenatal screening for syphilis is inadequate. Recently introduced point-of-care syphilis tests have high accuracy and demonstrate potential to increase coverage of antenatal screening. However, country-specific cost-effectiveness data for these tests are limited. The objective of this analysis was to evaluate the cost-effectiveness and budget impact of antenatal syphilis screening for 43 countries in SSA and estimate the impact of universal screening on stillbirths, neonatal deaths, congenital syphilis, and disability-adjusted life years (DALYs averted.The decision analytic model reflected the perspective of the national health care system and was based on the sensitivity (86% and specificity (99% reported for the immunochromatographic strip (ICS test. Clinical outcomes of infants born to syphilis-infected mothers on the end points of stillbirth, neonatal death, and congenital syphilis were obtained from published sources. Treatment was assumed to consist of three injections of benzathine penicillin. Country-specific inputs included the antenatal prevalence of syphilis, annual number of live births, proportion of women with at least one antenatal care visit, per capita gross national income, and estimated hourly nurse wages. In all 43 sub-Saharan African countries analyzed, syphilis screening is highly cost-effective, with an average cost/DALY averted of US$11 (range: US$2-US$48. Screening remains highly cost-effective even if the average prevalence falls from the current rate of 3.1% (range: 0.6%-14.0% to 0.038% (range: 0.002%-0.113%. Universal antenatal screening of pregnant women in clinics may reduce the annual number of stillbirths by up to 64,000, neonatal deaths by up to 25,000, and annual incidence of congenital syphilis by up to 32,000, and avert up to 2.6 million

National Strategic Plans (NSPs) for HIV/AIDS are country planning documents that set priorities for programmes and services, including a set of targets to quantify progress toward national and international goals. The inclusion of sex-disaggregated targets and targets to combat gender inequality is important given the high disease burden among young women and adolescent girls in Sub-Saharan Africa, yet no comprehensive gender-focused analysis of NSP targets has been performed. This analysis quantitatively evaluates national HIV targets, included in NSPs from eighteen Sub-Saharan African countries, for sex-disaggregation. Additionally, NSP targets aimed at reducing gender-based inequality in health outcomes are compiled and inductively coded to report common themes. On average, in the eighteen countries included in this analysis, 31% of NSP targets include sex-disaggregation (range 0-92%). Three countries disaggregated a majority (>50%) of their targets by sex. Sex-disaggregation in data reporting was more common for targets related to the early phases of the HIV care continuum: 83% of countries included any sex-disaggregated targets for HIV prevention, 56% for testing and linkage to care, 22% for improving antiretroviral treatment coverage, and 11% for retention in treatment. The most common target to reduce gender inequality was to prevent gender-based violence (present in 50% of countries). Other commonly incorporated target areas related to improving women's access to family planning, human and legal rights, and decision-making power. The inclusion of sex-disaggregated targets in national planning is vital to ensure that programmes make progress for all population groups. Improving the availability and quality of indicators to measure gender inequality, as well as evaluating programme outcomes by sex, is critical to tracking this progress. This analysis reveals an urgent need to set specific and separate targets for men and women in order to achieve an equitable

Spousal approval of family planning is critical for contraceptive use. Both contraceptive use rates and women's education are low in many West-African countries and this study examines the role of wives' education in spousal agreement on approval of family planning in two sub-Saharan West African countries. We used couples' data from Demographic Health Surveys in Senegal and in Niger, conducted in 2005 and 2006, respectively. Multiple logistic regression results using multilevel modeling show that the odds of spousal agreement on approval of family planning were slightly over three times [OR: 3.16; 95% CI: 1.32 to 7.57] in Senegal and were about three times [OR: 3.07; 95% CI: 1.64 to 5.76] in Niger higher for women with more than primary education. Findings suggest that improvement in women's education could lead to spousal agreement on approval of family planning, which may lead to use of family planning in sub-Saharan African countries.

The author analyzes migration from Africa to the developed countries of the north, focusing on the underlying logic and methods of such migration. He suggests that Africans see migration to the northern countries as a survival strategy and as an attempt to integrate themselves into the world economic system. The methods employed by African migrants to circumvent the increasing efforts to limit their numbers are described, with a focus on their use of regulations designed to aid the reunification of families. The author suggests that rich countries may have a moral obligation to allow migration from Africa, since its causes lie in the history of colonialism and the present and past exploitation of the developing countries by those of the north.

Interactions and Feedbacks Between Biomass Burning and Water Cycle Dynamics Across the Northern Sub-Saharan African Region

The northern sub-Saharan African (NSSA) region, bounded on the north and south by the Sahara and the Equator, respectively, and stretching from the West to the East African coastlines, has one of the highest biomass-burning rates per unit land area among all regions of the world. Because of the high concentration and frequency of fires in this region, with the associated abundance of heat release and gaseous and particulate smoke emissions, biomass-burning activity is believed to be one of the drivers of the regional carbon and energy cycles, with serious implications for the water cycle. A new interdisciplinary research effort sponsored by NASA is presently being focused on the NSSA region, to better understand the possible connection between the intense biomass burning observed from satellite year after year across the region and the rapid depletion of the regional water resources, as exemplified by the dramatic drying of Lake Chad. A combination of remote sensing and modeling approaches is being utilized in investigating multiple regional surface, atmospheric, and water-cycle processes, and inferring possible links between them. In this presentation, we will discuss preliminary results as well as the path toward improved understanding of the interrelationships and feedbacks between the biomass burning and the environmental change dynamics in the NSSA region.

This study investigated the impact of energy consumption and CO 2 emission on GDP (gross domestic product) growth and the financial development in thirty Sub Saharan African Countries. The panel model was used in this study from the period 1980 to 2008. The results showed that energy consumption had played an important role to increase both economic growth and the financial development in the investigated economies but with the consequence of high po llution. This study recommended that these countries should increase energy productivity by increasing energy efficiency, implementation of energy savings projects, energy conservation, and energy infrastructure outsourcing to achieve its financial development and GDP growth and to increase their investment on energy projects to achieve the full energy potential. -- Highlights: ► The impact of energy consumption, CO 2 emission on GDP and the financial development in the SSA countries was investigated. ► The panel model was implied in this study from the period 1980 to 2008. ► The results show energy consumption increased economic growth and the financial development but with higher pollution.

Background To date no validated instrument in the French language exists to screen for posttraumatic stress disorder (PTSD) in survivors of torture and organized violence. Objective The aim of this study is to adapt and validate the Harvard Trauma Questionnaire (HTQ) to this population. Method The adapted version was administered to 52 French-speaking torture survivors, originally from sub-Saharan African countries, receiving psychological treatment in specialized treatment centers. A structured clinical interview for DSM was also conducted in order to assess if they met criteria for PTSD. Results Cronbach's alpha coefficient for the HTQ Part 4 was adequate (0.95). Criterion validity was evaluated using receiver operating characteristic curve analysis that generated good classification accuracy for PTSD (0.83). At the original cut-off score of 2.5, the HTQ demonstrated high sensitivity and specificity (0.87 and 0.73, respectively). Conclusion Results support the reliability and validity of the French version of the HTQ. PMID:23233870

The European & Developing Countries Clinical Trials Partnership (EDCTP) is a partnership of European and sub-Saharan African countries that aims to accelerate the development of medical interventions against poverty-related diseases (PRDs). A bibliometric analysis was conducted to 1) measure research output from European and African researchers on PRDs, 2) describe collaboration patterns, and 3) assess the citation impact of clinical research funded by EDCTP. Disease-specific research publications were identified in Thomson Reuters Web of Science using search terms in titles, abstracts and keywords. Publication data, including citation counts, were extracted for 2003-2011. Analyses including output, share of global papers, normalised citation impact (NCI), and geographical distribution are presented. Data are presented as five-year moving averages. European EDCTP member countries accounted for ~33% of global research output in PRDs and sub-Saharan African countries for ~10% (2007-2011). Both regions contributed more to the global research output in malaria (43.4% and 22.2%, respectively). The overall number of PRD papers from sub-Saharan Africa increased markedly (>47%) since 2003, particularly for HIV/AIDS (102%) and tuberculosis (TB) (81%), and principally involving Southern and East Africa. For 2007-2011, European and sub-Saharan African research collaboration on PRDs was highly cited compared with the world average (NCI in brackets): HIV/AIDS 1.62 (NCI: 1.16), TB 2.11 (NCI: 1.06), malaria 1.81 (NCI: 1.22), and neglected infectious diseases 1.34 (NCI: 0.97). The NCI of EDCTP-funded papers for 2003-2011 was exceptionally high for HIV/AIDS (3.24), TB (4.08) and HIV/TB co-infection (5.10) compared with global research benchmarks (1.14, 1.05 and 1.35, respectively).

Infant and child mortality rates are among the most important indicators of child health, nutrition, implementation of key survival interventions, and the overall social and economic development of a population. In this paper, we investigate the role of coverage of maternal and child health (MNCH) interventions in contributing to declines in child mortality in sub-Saharan Africa. Data are from 81 Demographic and Health Surveys from 35 sub-Saharan African countries. Using ecological time-series and child-level regression models, we estimated the effect of MNCH interventions (summarized by the percent composite coverage index, or CCI) on child mortality with in the first 5 years of life net of temporal trends and covariates at the household, maternal, and child levels. At the ecologic level, a unit increase in standardized CCI was associated with a reduction in under-5 child mortality rate (U5MR) of 29.0 per 1,000 (95% CI: -43.2, -14.7) after adjustment for survey period effects and country-level per capita gross domestic product (pcGDP). At the child level, a unit increase in standardized CCI was associated with an odds ratio of 0.86 for child mortality (95% CI: 0.82-0.90) after adjustment for survey period effect, country-level pcGDP, and a set of household-, maternal-, and child-level covariates. MNCH interventions are important in reducing U5MR, while the effects of economic growth in sub-Saharan Africa remain weak and inconsistent. Improved coverage of proven life-saving interventions will likely contribute to further reductions in U5MR in sub-Saharan Africa.

Full Text Available Optimal nutrition is critical for human development and economic growth. Sub-Saharan Africa is facing high levels of food insecurity and only few sub-Saharan African countries are on track to eradicate extreme poverty and hunger by 2015. Effective research capacity is crucial for addressing emerging challenges and designing appropriate mitigation strategies in sub-Saharan Africa. A clear understanding of the operating environment for nutrition research in sub-Saharan Africa is a much needed prerequisite. We collected data on the barriers and requirements for conducting nutrition research in sub-Saharan Africa through semi-structured interviews with 144 participants involved in nutrition research in 35 countries in sub-Saharan Africa. A total of 133 interviews were retained for coding. The main barriers identified for effective nutrition research were the lack of funding due to poor recognition by policymakers of the importance of nutrition research and under-utilisation of research findings for developing policy, as well as an absence of research priority setting from within Africa. Current research topics were perceived to be mainly determined by funding bodies from outside Africa. Nutrition researchers argued for more commitment from policymakers at national level. The low capacity for nutrition research was mainly seen as a consequence of insufficient numbers of nutrition researchers, limited skills and a poor research infrastructure. In conclusion, African nutrition researchers argued how research priorities need to be identified by African stakeholders, accompanied by consensus building to enable creating a problem-driven national research agenda. In addition, it was considered necessary to promote interactions among researchers, and between researchers and policymakers. Multidisciplinary research and international and cross-African collaboration were seen as crucial to build capacity in sub-Saharan nutrition research.

Full Text Available Mercy Mvundura, Neeti Nundy, Maggie Kilbourne-Brook, Patricia S Coffey Technology Solutions Global Program, PATH, Seattle, WA, USA Background: Female condoms are the only currently available woman-initiated option that offers dual protection from pregnancy and sexually transmitted infections, including HIV. The Woman’s Condom is a new female condom designed to provide dual protection and to be highly pleasurable and acceptable. Objective: We sought to estimate the potential dual health impact and cost-effectiveness of a Woman’s Condom distribution program in 13 sub-Saharan African countries with HIV prevalence rates >4% among adults aged 15–49 years. We used two separate, publicly available models for this analysis, the Impact 2 model developed by Marie Stopes International and the Population Services International disability-adjusted life years (DALY calculator program. We estimated the potential numbers of pregnancies and DALYs averted when the Woman’s Condom is used as a family planning method and the HIV infections and DALYs averted when it is used as an HIV prevention method. Results: Programming 100,000 Woman’s Condoms in each of 13 countries in sub-Saharan Africa during a 1-year period could potentially prevent 194 pregnancies and an average of 21 HIV infections in each country. When using the World Health Organization CHOosing Interventions that are Cost-Effective (WHO-CHOICE criteria as a threshold to infer the potential cost-effectiveness of the Woman’s Condom, we found that the Woman’s Condom would be considered cost-effective. Conclusion: This was a first and successful attempt to estimate the impact of dual protection of female condoms. The health impact is greater for the use of the Woman’s Condom as an HIV prevention method than for contraception. Dual use of the Woman’s Condom increases the overall health impact. The Woman’s Condom was found to be very cost-effective in all 13 countries in our sample. Keywords

Sub Saharan African Terrorist Groups’ use of the Internet

Full Text Available Recent actions by French military forces in Niger and the global prominence of terrorist groups such as Al Shabaab and Boko Haram, have highlighted the growing counter terrorist focus on the countries of Sub Saharan Africa. Additionally in a post Bin Laden world and with the immanent withdrawal of coalition combat troops from Afghanistan, there is the possibility of Africa as a continent becoming the new front in the Global War on Terror ('Mben' et al., 2013. However, it is a mistake to assume that Africa’s story is uniformly one of violence and death. Vibrant cultures and a rugged entrepreneurial spirit have combined with a robust Internet backbone, to create the embryonic emergence of high tech hotspots across Africa. With rising IT literacy levels, more and more Africans are becoming connected to the information super highway on a daily basis (Graham, 2010. A tiny minority of these Africans are terrorists.

Energy-water-food nexus under financial constraint environment: good, the bad, and the ugly sustainability reforms in sub-Saharan African countries.

Environmental sustainability agenda are generally compromised by energy, water, and food production resources, while in the recent waves of global financial crisis, it mediates to increase the intensity of air pollutants, which largely affected the less developing countries due to their ease of environmental regulation policies and lack of optimal utilization of economic resources. Sub-Saharan African (SSA) countries are no exception that majorly hit by the recent global financial crisis, which affected the country's natural environment through the channel of unsustainable energy-water-food production. The study employed panel random effect model that addresses the country-specific time-invariant shocks to examine the non-linear relationship between water-energy-food resources and air pollutants in a panel of 19 selected SSA countries, for a period of 2000-2014. The results confirmed the carbon-fossil-methane environmental Kuznets curve (EKC) that turned into inverted U-shaped relationships in a panel of selected SSA countries. Food resources largely affected greenhouse gas (GHG), methane (CH 4 ), and nitrous oxide (N 2 O) emissions while water resource decreases carbon dioxide (CO 2 ), fossil fuel, and CH 4 emissions in a region. Energy efficiency improves air quality indicators while industry value added increases CO 2 emissions, fossil fuel energy, and GHG emissions. Global financial crisis increases the risk of climate change across countries. The study concludes that although SSA countries strive hard to take some "good" initiatives to reduce environmental degradation in a form of improved water and energy sources, however, due to lack of optimal utilization of food resources and global financial constraints, it leads to "the bad" and "the ugly" sustainability reforms in a region.

PEPFAR Funding and Reduction in HIV Infection Rates in 12 Focus Sub-Saharan African Countries: A Quantitative Analysis

Directory of Open Access Journals (Sweden)

Roger J. Chin, MA, MPA

2015-04-01

Full Text Available Background: HIV and AIDS continue to have a calamitous effect on individuals living on the continent of Africa. U.S. President George W. Bush implemented the President’s Emergency Plan for AIDS Relief (PEPFAR with the objective of committing approximately $15 billion from 2004 through 2008 to assist with the reduction of the HIV pandemic worldwide. The majority of the PEPFAR policy and funding focused on 12 countries in sub-Saharan Africa: Botswana, Cote d’Ivoire, Ethiopia, Kenya, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Uganda, and Zambia. The policy question this research paper seeks to analyze is whether the PEPFAR funding (as a % of Gross Domestic Product (GDP allocated to the 12 countries in Africa had any effect on the decrease of HIV infection rates of males and females between the ages of 15 and 49. Methods: A fixed-effects panel regression analysis was conducted to determine if this association exists. This study examined the 12 African countries that received PEPFAR funding over the years 2002 to 2010; even though PEPFAR was only active from 2004 through 2008, this research included two years prior and two years after this timeframe in order to better estimate the effect of PEPFAR funding on HIV reduction. Results: The results illustrate that on average, ceteris paribus, for every 1 percentage point increase in PEPFAR funding per GDP a country received, the country’s HIV infection rate decreased by 0.355 percentage points. Conclusions and Global Health Implications: While the empirical findings in this study suggested that the correlation between PEPFAR funding and HIV reduction is statistically significant, the practical significance is perhaps less obvious. Arguably, the reduction rate should be higher given the extent of funding targeted to this project. The conclusion of this research provides suggestions on future research and the policy implications of PEPFAR.

This study reviewed grey literature to assess clinical nursing and midwifery research conducted in southern and eastern African countries over the past decade. The shortage of published nursing research from African countries severely limits the ability of practicing nurses and midwives to base clinical decisions on solid evidence. However, little is known regarding unpublished or unindexed clinical research ('grey literature'), a potentially rich source of information. Identifying these sources may reveal resources to assist nurses in providing evidence-based care. This scoping review of grey literature on clinical nursing and midwifery research in southern and eastern African countries helped to identify gaps in research and assess whether these gaps differ from published research. Systematic searches of grey literature were performed. Research was included if it was conducted by nurses in 1 of 25 southern or eastern African countries, between 2004 and 2014 and included patient outcomes. Data were extracted on location, institution, research topic, institutional connections and author information. Chi-square tests were performed to compare differences between indexed and non-indexed literature. We found 262 studies by 287 authors from 17 southern and eastern African countries covering 13 topics. Although all topics were also found in indexed literature and there were statistically significant differences between the number of times, fewer topics were covered in grey literature vs. indexed. Patient satisfaction and experience and traditional health practices were more likely to be published, whereas chronic disease, assault and paediatric-related research were less often published. Generally, there is a paucity of clinical nursing research in this region. This could reflect the shortage of nurses prepared to conduct research in this region. Nurses may find additional resources for evidence in the grey literature. A complete understanding of the state of nursing

An approach to rural distribution network design for sub-Saharan Africa

The bulk of rural populations in sub-Saharan Africa have no access to electricity and are under-served by any other form of modern infrastructure. The cost of infrastructure to mainly scattered communities has been perennially cited as largely to blame. Quite often rural networks are overdesigned, resulting in under utilization and, therefore, costly overheads. One reason often cited for the overspecification is anticipation of load growth. In most sub-Sahara African rural areas, however, economic growth rates are low, and a designer has no justification in specifying an infrastructure capacity exceeding more than a few percent of existing consumer requirements. This paper proposes methods that critically look at the geometry of small grid network designs to address the construction challenges in rural sub-Saharan Africa

2012-04-01

The Middle-East, mostly at its southern edge together with North Africa, the northern edge of the Sahara Desert, are located at the boundary between high- to-mid latitude and tropical-subtropical climate systems. The geographical duality of desert adjacent to Mediterranean-type climate regions played and still plays a major role on the water availability. Thanks to the number of important paleoclimate studies that been made on accurate dating of cave speleothems in Southern Arabia and Oman (Fleitmann et al., 2011) and in the northeast Sahara, the Negev Desert Israel (Vaks et al., 2010) and the study of sapropels in Eastern and central Mediterranean (Almogi-Labin et al., 2009; Osborne et al, 2008), it is clear that the region was graced with water during peak interglacials when the African monsoon and westerly storm/rainfall systems intensified. Northward penetration of the Inter Tropical Convergence Zone over the Arabian and African continents resulted in increased discharge of the Nile River and rivers that emerged from central Sahara into the Eastern Mediterranean Sea. Correspondingly, enhanced westerly wind activity led to an increase in rainfall from Atlantic-Mediterranean sources over the entire Mediterranean basin, which even penetrated south into the north-east corner of the Sahara Desert. The Saharo-Arabian Desert became narrower and climatic "windows" opened for the dispersal of hominids and animals out of the African continent at 250-239, 210-193, 138-120, 108-98, 87-84 and 10-6.5 ka BP, with severe dry conditions in between. Greening of the Sahara Desert at these intervals is supported also by various marine and terrestrial records, such as corals, lakes, tufa deposits and archeological findings. Dry conditions prevailed in the Sahara desert during glacials. This is in contrast to the climatic conditions in the Eastern Mediterranean coastal region and the Jordan Rift Valley (Bar-Matthews et al., 2003; Lisker et al., 2010), where water was available for

Archaeology can provide insight into interactions of climate change and human activities in sensitive areas such as the Sahara, to the benefit of both disciplines. Such analyses can help set bounds on climate change projections, perhaps identify elements of tipping points, and provide constraints on models. The opportunity exists to more precisely constrain the relationship of natural solar and climate interactions, improving understanding of present and future anthropogenic forcing. We are beginning to explore the relationship of human occupation of the Sahara and long-term solar irradiance variations synergetic with changes in atmospheric-ocean circulation patterns. Archaeological and climate records for the last 12 K years are gaining adequate precision to make such comparisons possible. We employ a range of climate records taken over the globe (e.g. Antarctica, Greenland, Cariaco Basin, West African Ocean cores, records from caves) to identify the timing and spatial patterns affecting Saharan climate to compare with archaeological records. We see correlation in changing ocean temperature patterns approx. contemporaneous with drying of the Sahara approx. 6K years BP. The role of radar images and other remote sensing in this work includes providing a geographically comprehensive geomorphic overview of this key area. Such coverage is becoming available from the Japanese PALSAR radar system, which can guide field work to collect archaeological and climatic data to further constrain the climate change chronology and link to models. Our initial remote sensing efforts concentrate on the Gilf Kebir area of Egypt.

Globally, the nursing shortage has been deemed a crisis, but African countries have been hit hardest. Therefore, it is of utmost importance nurses use the best available evidence and that nursing research is targeted to address gaps in the evidence. To achieve this, an understanding of what is currently available and identification of gaps in clinical nursing research is critical. We performed a scoping review of existing literature to assess clinical nursing research conducted in all African countries over the past decade, identify gaps in clinical nursing and midwifery research, determine whether they match with health priorities for countries, and define priorities for regional clinical nursing research agendas to improve health outcomes. This is a scoping review of published clinical nursing research conducted in African countries. Systematic searches of literature published between January 01, 2004 and September 15, 2014 were performed in PubMed, Medline, CINHAL, and Embase. Research was included if it was conducted by nurses, included data obtained in African countries or regions within the African continent, published in a peer-reviewed journal with an abstract, and included patient outcomes. Abstracts were independently reviewed for inclusion by two authors. The following data were extracted: countries of publication and study, study type and design, journal, language, and topics of research. Gaps in the literature were identified. Initially, 1091 papers were identified with a final sample of 73 articles meeting inclusion criteria. Studies used 12 designs, were published in 35 journals published in five countries (including two African countries); 29% of the research was published in a single journal (Curatonis). Research was mostly qualitative (57%) and included twenty countries in Africa (38%). There were 12 major topics of study, most often midwifery/maternal/child health (43%), patient experiences (38%), and human immunodeficiency virus (HIV

Full Text Available To assess social inequalities in the use of antenatal care (ANC, facility based delivery (FBD, and modern contraception (MC in two contrasting groups of countries in sub-Saharan Africa divided based on their progress towards maternal mortality reduction. Six countries were included in this study. Three countries (Ethiopia, Madagascar, and Uganda had 4.5% average annual reduction rate while another three (Cameroon, Zambia, and Zimbabwe had >550 MMR in 2010 with only <1.5% average annual reduction rate. All of these countries had at least three rounds of Demographic and Health Surveys (DHS before 2012. We measured rate ratios and differences, as well as relative and absolute concentration indices in order to examine within-country geographical and wealth-based inequalities in the utilization of ANC, FBD, and MC. In the countries which have made sufficient progress (i.e. Ethiopia, Madagascar, and Uganda, ANC use increased by 8.7, 9.3 and 5.7 percent, respectively, while the utilization of FBD increased by 4.7, 0.7 and 20.2 percent, respectively, over the last decade. By contrast, utilization of these services either plateaued or decreased in countries which did not make progress towards reducing maternal mortality, with the exception of Cameroon. Utilization of MC increased in all six countries but remained very low, with a high of 40.5% in Zimbabwe and low of 16.1% in Cameroon as of 2011. In general, relative measures of inequalities were found to have declined overtime in countries making progress towards reducing maternal mortality. In countries with insufficient progress towards maternal mortality reduction, these indicators remained stagnant or increased. Absolute measures for geographical and wealth-based inequalities remained high invariably in all six countries. The increasing trend in the utilization of maternal care services was found to concur with a steady decline in maternal mortality. Relative inequality declined overtime in countries

To provide a comprehensive understanding of neurology training from the sub-Saharan African perspective. A 40-question survey was distributed to attendees of the 7th annual sub-Saharan African neurology teaching course in Khartoum, Sudan (2015). Themes included the student body, faculty, curriculum, assessment and examinations, technology, and work hours and compensation. Of 19 responding countries, 10 had no formal neurology training programs; Burkina Faso, Cameroon, Republic of the Congo, and Mozambique had an adult neurology program; Ethiopia, Madagascar, Nigeria, Senegal, and South Africa had adult and pediatric neurology programs (training duration range = 3-6 years). There was a median of 2.5 full-time neurologists on the teaching faculty at the respondents' training institutions (neurologists on-faculty:in-country ratio = 0.48), with the lowest ratios in Sudan and Nigeria. Neurology was perceived to be a competitive specialty for entrance in 57% of countries, with 78% of respondents reporting a requisite entrance examination. Ninety-five percent had access to a personal smartphone, 62% used the Internet more than occasionally, and 60% had access to online neurology journals. The average number of weekly work hours was 51 (range = 40-75), and average monthly salary among those earning income was 1,191 USD (range = 285-3,560). Twenty percent of respondents reported paying for training. The most common barriers to neurology postgraduate education were few training programs and lack of training in neurodiagnostic tests. Among 17 reporting countries, there is an estimated average of 0.6 neurologists per million people. Neurology training programs in sub-Saharan Africa are relatively limited in number and have several unmet needs including a small cadre of faculty and an opportunity to standardize curricula and financing of programs.

Racial Disparities in the Pathogenesis of Type 2 Diabetes and its Subtypes in the African Diaspora: A New Paradigm.

Gaillard, Trudy R; Osei, Kwame

2016-03-01

The global epidemic of diabetes has extended to the developing countries including Sub-Sahara Africa. In this context, blacks with type 2 diabetes in the African Diaspora continue to manifest 1.5-2 times higher prevalent rates than in their white counterparts. Previous studies have demonstrated that blacks with and without type 2 diabetes have alterations in hepatic and peripheral insulin sensitivity, beta-cell function, and hepatic insulin clearance as well as hepatic glucose dysregulation when compared to whites. In addition, non-diabetic blacks in the African Diaspora manifest multiple metabolic mediators that predict type 2 diabetes and its subtypes. These pathogenic modifiers include differences in subclinical inflammation, oxidative stress burden, and adipocytokines in blacks in the African Diaspora prior to clinical diagnosis. Consequently, blacks in the African Diaspora manifest subtypes of type 2 diabetes, including ketosis-prone diabetes and J type diabetes. Given the diversity of type 2 diabetes in blacks in the African Diaspora, we hypothesize that blacks manifest multiple early pathogenic defects prior to the diagnosis of type 2 diabetes and its subtypes. These metabolic alterations have strong genetic component, which appears to play pivotal and primary role in the pathogenesis of type 2 diabetes and its subtypes in blacks in the African Diaspora. However, environmental factors must also be considered as major contributors to the higher prevalence of type 2 diabetes and its subtypes in blacks in the African Diaspora. These multiple alterations should be targets for early prevention of type 2 diabetes in blacks in the African Diaspora.

North African populations are distinct from sub-Saharan Africans based on cultural, linguistic, and phenotypic attributes; however, the time and the extent of genetic divergence between populations north and south of the Sahara remain poorly understood. Here, we interrogate the multilayered history of North Africa by characterizing the effect of hypothesized migrations from the Near East, Europe, and sub-Saharan Africa on current genetic diversity. We present dense, genome-wide SNP genotyping array data (730,000 sites) from seven North African populations, spanning from Egypt to Morocco, and one Spanish population. We identify a gradient of likely autochthonous Maghrebi ancestry that increases from east to west across northern Africa; this ancestry is likely derived from “back-to-Africa” gene flow more than 12,000 years ago (ya), prior to the Holocene. The indigenous North African ancestry is more frequent in populations with historical Berber ethnicity. In most North African populations we also see substantial shared ancestry with the Near East, and to a lesser extent sub-Saharan Africa and Europe. To estimate the time of migration from sub-Saharan populations into North Africa, we implement a maximum likelihood dating method based on the distribution of migrant tracts. In order to first identify migrant tracts, we assign local ancestry to haplotypes using a novel, principal component-based analysis of three ancestral populations. We estimate that a migration of western African origin into Morocco began about 40 generations ago (approximately 1,200 ya); a migration of individuals with Nilotic ancestry into Egypt occurred about 25 generations ago (approximately 750 ya). Our genomic data reveal an extraordinarily complex history of migrations, involving at least five ancestral populations, into North Africa. PMID:22253600

Full Text Available Microfinance institutions (MFIs have the dual objective of providing social welfare and financial stability. We evaluated the financial efficiency of MFIs in sub-Saharan African countries by comparing their regional performances during the period 2004-2013. We addressed prevailing MFI heterogeneity by using the concept of "metafrontier". The results showed that on an average, more than half the MFIs showed a drop in productivity. The measure of how much one country gets closer to or further away from world frontier technology is commonly known as the TGC score. In world frontier technology, East and South Asian countries have taken the lead (TGC score 1.0048 while sub-Saharan African countries lag behind (TGC score 1.0020. Most East and South Asian countries have a TGC score of 1, and most sub-Saharan African countries have a TGC score less than 1. This signifies that Asian countries lead world frontier technology and most African countries do not. The decomposition of efficiency scores showed that with regard to technical changes, African nations had progressed on average only 0.01%, and efficiency change scores had regressed by 0.59% annually.

Corruption in Sub-Saharan Africa: A practical-theological response

Directory of Open Access Journals (Sweden)

Petria M. Theron

2013-11-01

Full Text Available On the 2012 Corruption Perceptions Index of Transparency International, 89.6%of Sub-Saharan African countries received scores below 50, where a score of zero signifies that the country is highly corrupt and a score of 100 declares a country free of corruption. From these results, it seems as if Sub-Saharan African countries are quite vulnerable to corruption. In this article, the question whether certain traits in the Sub-Saharan African culture such as communalism, gift giving and a shame culture could in some situations influence people’s perception of, and their possible openness towards, certain forms of corruption was investigated. The research showed that cultural traits do influence people’s behaviour and that there are certain traits in the Sub-Saharan African culture that might sanction corruption. In response to these findings, some preliminary suggestions were proposed as to how Christians living in Africa could evaluate their cultural practices in the light of God’s Word and from a reformed theological paradigm. Instead of succumbing to the pressure posed by their culture to participate in immoral or corrupt activities, they could contribute to a moral regeneration on the African continent.

The impacts of oil price fluctuations on the economy of sub-Saharan African countries, importers of oil products

International Nuclear Information System (INIS)

Sacko, I.

1997-01-01

This work comprises three parts. The first part aims at presenting the energy situation of sub-Saharan African (SSA) countries grouped in five regions. Because of the demographic pressure and of the petroleum shocks, the commercial energy consumption is growing up rapidly and the energy prices are high for the end-users (because the energy is imported and paid in dollars, and the fiscality share is increased by governments in the case of prices drop in the international market). The important problem of wood fuel is considered, together with the energy-economic growth relations and the determining factors of the energy demand in SSA. Some econometric relations are tested. The second part analyzes the mechanisms generated by petroleum shocks and counter-shocks, and stresses first on the transfers induced by these fluctuations. Then, it presents some macro-economical models which try to integrate the effects of a petroleum shock and makes some calculations based on a decomposition of imports and exports global and partial coefficients. Some important conclusions are inferred from this study: 1 - the second petroleum shock strikes more seriously the oil importing SSA countries because they do not benefit from a favorable international context, like during the first shock (also because the second shock is accompanied by a dollar shock); 2 - the absence of symmetry in oil shocks-counter-shocks; 3 - the crisis of SSA countries is not only of petroleum origin but is also linked with the drop of the export incomes (which itself is partially explained by the impact of petroleum shocks on the industrialized economies), with their bad insertion in the world economy, and with unsuitable domestic economies. The third part proposes some solutions to attenuate the energy and economical difficulties of these countries. It is necessary to implement an energy planning mainly based on the mastery of the demand and on a better management of local resources. The policies of

Whereas mobile phone-based surveillance has the potential to provide real-time validated data for disease clustering and prompt respond and investigation, little evidence is available on current practice in sub-Sahara Africa. The objective of this review was to examine mobile phone-based mHealth interventions for Public Health surveillance in the region. We conducted electronic search in MEDLINE, EMBASE, IEE Xplore, African Index Medicus (AIM), BioMed Central, PubMed Central (PMC), the Public Library of Science (PLoS) and IRIS for publications used in the review. In all, a total of nine studies were included which focused on infectious disease surveillance of malaria (n = 3), tuberculosis (n = 1) and influenza-like illnesses (n = 1) as well as on non-infectious disease surveillance of child malnutrition (n = 2), maternal health (n = 1) and routine surveillance of various diseases and symptoms (n = 1). Our review revealed that mobile phone-based surveillance projects in the sub-Saharan African countries are on small scale, fragmented and not well documented. We conclude by advocating for a strong drive for more research in the applied field as well as a better reporting of lessons learned in order to create an epistemic community to help build a more evidence-based field of practice in mHealth surveillance in the region.

There is little information on the extent to which African countries are addressing alcohol consumption and alcohol-related harm, which suggests that evaluations of national alcohol policies are needed in this region. The aim of this article is to examine the strength of a mix of national alcohol control policies in African countries, as well as the relationship between alcohol policy restrictiveness scores and adult alcohol per capita consumption (APC) among drinkers at the national level. We examined national alcohol policies of 46 African countries, as of 2012, in four regulatory categories (price, availability, marketing and drink-driving), and analyzed the restrictiveness of national alcohol policies using an adapted Alcohol Policy Index (API). To assess the validity of the policy restrictiveness scores, we conducted correlational analyses between policy restrictiveness scores and APC among drinkers in 40 countries. Countries attained a mean score of 44.1 of 100 points possible, ranging from 9.1 (Sao Tomé and Principe) to 75.0 (Algeria), with low scores indicating low policy restrictiveness. Policy restrictiveness scores were negatively correlated with and APC among drinkers (rs = -0.353, P = 0.005). There is great variation in the strength of alcohol control policies in countries throughout the African region. Tools for comparing the restrictiveness of alcohol policies across countries are available and are an important instrument to monitor alcohol policy developments. The negative correlation between policy restrictiveness and alcohol consumption among drinkers suggests the need for stronger alcohol policies as well as increased training and capacity building at the country level. © The Author 2015.

Financing renewable energy in developing countries. Drivers and barriers for private finance in sub-Saharan Africa

Energy Technology Data Exchange (ETDEWEB)

NONE

2012-02-15

The focus of this report is to identify and portray current barriers to the scaling up of private investment and finance for electricity generation from renewable energy sources in the sub-Saharan region. Best practice in tackling these barriers is identified, partly from a literature review but especially from the results of a survey conducted among 36 financial institutions that are UNEP Finance Initiative members and two non-member banks (all survey respondents have experience in the field of energy infrastructure finance). Promising avenues in the areas of local policy reform, incentive mechanisms and international de-risking instruments are highlighted. In particular, this report addresses the following questions: (a) Why are sub-Saharan Africa and developing countries elsewhere failing to expand electricity generation from renewable sources? What are the barriers to such expansion? What is keeping the risk-return profile of renewable energy investments in sub-Saharan Africa unattractive and projects commercially unviable?; (b) What have been the experiences of private sector lenders and investors in the area of renewable energy projects in developing countries? What barriers and drivers have they encountered, and how can these experiences be of use in sub-Saharan Africa?; (c) What can be learned from the modest but encouraging successes of a few sub-Saharan African countries? Can these results be replicated? What was done in these countries to improve the risk-return profile of renewable energy and unlock private finance?.

Scale-up of malaria interventions over the last decade have yielded a significant reduction in malaria transmission and disease burden in sub-Saharan Africa. We estimated economic gradients in the distribution of these efforts and of their impacts within and across endemic countries. Using Demographic and Health Surveys we computed equity metrics to characterize the distribution of malaria interventions in 30 endemic countries proxying economic position with an asset-wealth index. Gradients were summarized in a concentration index, tabulated against level of coverage, and compared among interventions, across countries, and against respective trends over the period 2005-2015. There remain broad differences in coverage of malaria interventions and their distribution by wealth within and across countries. In most, economic gradients are lacking or favor the poorest for vector control; malaria services delivered through the formal healthcare sector are much less equitable. Scale-up of interventions in many countries improved access across the wealth continuum; in some, these efforts consistently prioritized the poorest. Expansions in control programs generally narrowed coverage gaps between economic strata; gradients persist in countries where growth was slower in the poorest quintile or where baseline inequality was large. Despite progress, malaria is consistently concentrated in the poorest, with the degree of inequality in burden far surpassing that expected given gradients in the distribution of interventions. Economic gradients in the distribution of interventions persist over time, limiting progress toward equity in malaria control. We found that, in countries with large baseline inequality in the distribution of interventions, even a small bias in expansion favoring the least poor yielded large gradients in intervention coverage while pro-poor growth failed to close the gap between the poorest and least poor. We demonstrated that dimensions of disadvantage

To measure within-country wealth-related inequality in the health service coverage gap of maternal and child health indicators in sub-Saharan Africa and quantify its contribution to the national health service coverage gap. Coverage data for child and maternal health services in 28 sub-Saharan African countries were obtained from the 2000-2008 Demographic Health Survey. For each country, the national coverage gap was determined for an overall health service coverage index and select individual health service indicators. The data were then additively broken down into the coverage gap in the wealthiest quintile (i.e. the proportion of the quintile lacking a required health service) and the population attributable risk (an absolute measure of within-country wealth-related inequality). In 26 countries, within-country wealth-related inequality accounted for more than one quarter of the national overall coverage gap. Reducing such inequality could lower this gap by 16% to 56%, depending on the country. Regarding select individual health service indicators, wealth-related inequality was more common in services such as skilled birth attendance and antenatal care, and less so in family planning, measles immunization, receipt of a third dose of vaccine against diphtheria, pertussis and tetanus and treatment of acute respiratory infections in children under 5 years of age. The contribution of wealth-related inequality to the child and maternal health service coverage gap differs by country and type of health service, warranting case-specific interventions. Targeted policies are most appropriate where high within-country wealth-related inequality exists, and whole-population approaches, where the health-service coverage gap is high in all quintiles.

The impact of HIV/AIDS on human development in African countries.

Science.gov (United States)

Boutayeb, Abdesslam

2009-11-18

In the present paper, we consider the impact of HIV/AIDS on human development in African countries, showing that, beyond health issues, this disease should and must be seen as a global development concern, affecting all components of human development. Consequently, we stress the necessity of multidisciplinary approaches that model, estimate and predict the real impact of HIV/AIDS on human development of African countries in order to optimise the strategies proposed by national countries, international institutions and their partners. In our search strategy, we relied on secondary information, mainly through National Human Development Reports of some African countries and regular publications released by the United Nations (UN), United Nations Development Programme (UNDP), World Health Organization (WHO) and the World Bank. We restricted ourselves to reports dealing explicitly with the impact of HIV/AIDS on human development in African countries. HIV/AIDS is affecting the global human development of African countries through its devastating impact on health and demographic indicators such as life expectancy at birth, healthcare assistance, age and sex distribution, economic indicators like income, work force, and economic growth, education and knowledge acquisition and other indicators like governance, gender inequality and human rights. On the basis of the national reports reviewed, it appears clearly that HIV/AIDS is no longer a crisis only for the healthcare sector, but presents a challenge to all sectors. Consequently, HIV/AIDS is a development question and should be viewed as such. The disease is impeding development by imposing a steady decline in the key indicators of human development and hence reversing the social and economic gains that African countries are striving to attain. Being at the same time a cause and consequence of poverty and underdevelopment, it constitutes a challenge to human security and human development by diminishing the chances of

Background Cholera burden in Africa remains unknown, often because of weak national surveillance systems. We analyzed data from the African Cholera Surveillance Network (www.africhol.org). Methods/ Principal findings During June 2011–December 2013, we conducted enhanced surveillance in seven zones and four outbreak sites in Togo, the Democratic Republic of Congo (DRC), Guinea, Uganda, Mozambique and Cote d’Ivoire. All health facilities treating cholera cases were included. Cholera incidences were calculated using culture-confirmed cholera cases and culture-confirmed cholera cases corrected for lack of culture testing usually due to overwhelmed health systems and imperfect test sensitivity. Of 13,377 reported suspected cases, 34% occurred in Conakry, Guinea, 47% in Goma, DRC, and 19% in the remaining sites. From 0–40% of suspected cases were aged under five years and from 0.3–86% had rice water stools. Within surveillance zones, 0–37% of suspected cases had confirmed cholera compared to 27–38% during outbreaks. Annual confirmed incidence per 10,000 population was Conakry had corrected incidences of 20.2 and 5.8 respectively, while the other zones a median of 0.3. During outbreaks, corrected incidence varied from 2.6 to 13.0. Case fatality ratios ranged from 0–10% (median, 1%) by country. Conclusions/Significance Across different African epidemiological contexts, substantial variation occurred in cholera incidence, age distribution, clinical presentation, culture confirmation, and testing frequency. These results can help guide preventive activities, including vaccine use. PMID:27186885

Several studies of environmental samples indicate that the levels of many persistent organic pollutants (POPs) are increasing in Africa, but few studies have been conducted in humans. Simultaneously, many African countries are experiencing a rapid economic growth and implementing information and communication technologies (ICT). These changes have generated high amounts of electronic waste (e-waste) that have not been adequately managed. We tested the hypothesis that the current levels of two main classes of POPs in Western and Central African countries are affected by the degree of socioeconomic development. We measured the levels of 36 POPs in the serum of recent immigrants (N = 575) who came from 19 Sub-Saharan countries to the Canary Islands (Spain). We performed statistical analyses on their anthropometric and socioeconomic data. High median levels of POPs were found in the overall sample, with differences among the countries. Organochlorine pesticide (OCP) and polychlorinated biphenyl (PCB) levels increased with age. People from low-income countries had significantly higher OCP levels and much lower PCB levels than those from high-income countries. We found a significant association between the implementation of ICT and PCB contamination. Immigrants from the countries with a high volume of imports of second-hand electronic equipment had higher PCB levels. The economic development of Africa and the e-waste generation have directly affected the levels of POPs. The POP legacies of these African populations most likely are due to the inappropriate management of the POPs' residues. - Highlights: • Higher levels of organochlorine pesticides in Africans from low-income countries • Higher levels of PCBs in Africans from high-income countries • Levels of PCBs are significantly higher in people from West Africa. • Significant association between implementation of ICT and PCB contamination • High volume of second-hand electronic equipment is associated

The aim of this paper is to provide new empirical evidence on the relationship between energy consumption and economic growth for 21 African countries over the period from 1970 to 2006, using recently developed panel cointegration and causality tests. The countries are divided into two groups: net energy importers and net energy exporters. It is found that there exists a long-run equilibrium relationship between energy consumption, real GDP, prices, labor and capital for each group of countries as well as for the whole set of countries. This result is robust to possible cross-country dependence and still holds when allowing for multiple endogenous structural breaks, which can differ among countries. Furthermore, we find that decreasing energy consumption decreases growth and vice versa, and that increasing energy consumption increases growth, and vice versa, and that this applies for both energy exporters and importers. Finally, there is a marked difference in the cointegration relationship when country groups are considered. - Highlights: > We assess the energy consumption and economic growth nexus in 21 African countries. > There exists a long-run relationship between energy consumption and economic growth. > This result is robust to cross-country dependence and for structural breaks. > Our findings finally support the feedback hypothesis of bidirectional causality.

Linking the sub-Saharan and West Eurasian gene pools: maternal and paternal heritage of the Tuareg nomads from the African Sahel.

The Tuareg presently live in the Sahara and the Sahel. Their ancestors are commonly believed to be the Garamantes of the Libyan Fezzan, ever since it was suggested by authors of antiquity. Biological evidence, based on classical genetic markers, however, indicates kinship with the Beja of Eastern Sudan. Our study of mitochondrial DNA (mtDNA) sequences and Y chromosome SNPs of three different southern Tuareg groups from Mali, Burkina Faso and the Republic of Niger reveals a West Eurasian-North African composition of their gene pool. The data show that certain genetic lineages could not have been introduced into this population earlier than approximately 9000 years ago whereas local expansions establish a minimal date at around 3000 years ago. Some of the mtDNA haplogroups observed in the Tuareg population were involved in the post-Last Glacial Maximum human expansion from Iberian refugia towards both Europe and North Africa. Interestingly, no Near Eastern mtDNA lineages connected with the Neolithic expansion have been observed in our population sample. On the other hand, the Y chromosome SNPs data show that the paternal lineages can very probably be traced to the Near Eastern Neolithic demic expansion towards North Africa, a period that is otherwise concordant with the above-mentioned mtDNA expansion. The time frame for the migration of the Tuareg towards the African Sahel belt overlaps that of early Holocene climatic changes across the Sahara (from the optimal greening approximately 10 000 YBP to the extant aridity beginning at approximately 6000 YBP) and the migrations of other African nomadic peoples in the area.

The post-2015 development agenda for diabetes in sub-Saharan Africa: challenges and future directions.

2015-01-01

Diabetes is one of the non-communicable diseases (NCDs) which is rising significantly across sub-Saharan African (SSA) countries and posing a threat to the social, economic, and cultural fabric of the SSA population. The inclusion of NCDs into the post-2015 development agenda along with the global monitoring framework provides an opportunity to monitor progress of development programmes in developing countries. This paper examines challenges associated with dealing with diabetes within the development agenda in SSA and explores some policy options. This conceptual review draws from a range of works published in Medline and the grey literature to advance the understanding of the post-2015 development agenda and how it relates to NCDs. The paper begins with the burden of diabetes in sub-Sahara Africa and then moves on to examine challenges associated with diabetes prevention, treatment, and management in Africa. It finishes by exploring policy implications. With regards to development programmes on NCDs in the SSA sub-continent, several challenges exist: 1) poor documentation of risk factors, 2) demographic transitions (rapid urbanisation and ageing), 3) the complementary role of traditional healers, 4) tuberculosis and the treatment of the acquired immunodeficiency syndrome as risk factors for diabetes, 5) diabetes in complex emergencies, 6) diabetes as an international development priority and not a policy agenda for many SSA countries, and 7) poorly regulated food and beverage industry. For the post-2015 development agenda for NCDs to have an impact, sufficient investments will be needed to address legislative, technical, human, and fiscal resource constraints through advocacy, accountability, political leadership, and effective public-private partnership. Striking the right balance between competing demands and priorities, policies, and implementation strategies hold the key to an effective response to diabetes in SSA countries.

Conventional energy supply and impacts in African cities; L'approvisionnement en energie traditionnelle et impacts dans les villes africaines

Energy Technology Data Exchange (ETDEWEB)

Dianka, M. [GAA/RPTES, Dakar (Senegal)

2002-03-01

Before discussing supplies of conventional energy in sub-Sahara, one must consider certain information and important facts. In each country, the supplies in conventional energy are moving within a holistic frame with inter sectoral links between energy and the other problems encountered by national economies: forestry, agriculture, livestock production, demography, urbanization, poverty. In this light, the author indicated it might be wise to take into account a few major facts that underlay the Urban Demand in Domestic Combustibles before devising sustainable solutions. It was explained that in most of the African countries located South of the Sahara, there was a trend toward greater urbanization and the movement of refugees. In large part, these trends are the result of poverty, conflicts, or the degradation of the environment. Therefore, it follows that energy consumption is concentrated in cities. In countries such as Burkina Faso or Zambia, a large proportion of urban dwellers still rely on biomass to meet their culinary needs, as well as heating and other tasks. Urbanization occurred in an anarchic manner, and the forests that used to encircle cities are fast disappearing, leaving in their wake pollution. In addition, the supply sources of biomass are farther than ever. Nowadays, the supply of wood energy for Dakar, the capital of Senegal, extends over an area covering 500 kilometres, rather than the 100 kilometres it required thirty years ago. Wood energy in cities is considered to be the major cause of deforestation. Health problems such as asthma are caused by the smoke emanating from the fires used to cook meals. A few solutions are beginning to emerge, linked to the presence of youth and women in the cities, as well as sufficient manpower to implement the solutions. 9 refs., 3 figs.

2014-01-01

Background Development of human resources for eye health (HReH) is a major focus of the Global Action Plan 2014 to 2019 to reduce the prevalence of avoidable visual impairment by 25% by the year 2019. The eye health workforce is thought to be much smaller in sub-Saharan Africa than in other regions of the world but data to support this for policy-making is scarce. We collected HReH and cataract surgeries data from 21 countries in sub-Sahara to estimate progress towards key suggested population-based VISION 2020 HReH indicators and cataract surgery rates (CSR) in 2011. Methods Routinely collected data on practitioner and surgery numbers in 2011 was requested from national eye care coordinators via electronic questionnaires. Telephone and e-mail discussions were used to determine data collection strategies that fit the national context and to verify reported data quality. Information was collected on six practitioner cadres: ophthalmologists, cataract surgeons, ophthalmic clinical officers, ophthalmic nurses, optometrists and ‘mid-level refractionists’ and combined with publicly available population data to calculate practitioner to population ratios and CSRs. Associations with development characteristics were conducted using Wilcoxon rank sum tests and Spearman rank correlations. Results HReH data was not easily available. A minority of countries had achieved the suggested VISION 2020 targets in 2011; five countries for ophthalmologists/cataract surgeons, four for ophthalmic nurses/clinical officers and two for CSR. All countries were below target for optometrists, even when other cadres who perform refractions as a primary duty were considered. The regional (sample) ratio for surgeons (ophthalmologists and cataract surgeons) was 2.9 per million population, 5.5 for ophthalmic clinical officers and nurses, 3.7 for optometrists and other refractionists, and 515 for CSR. A positive correlation between GDP and CSR as well as many practitioner ratios was observed

Collaboration between Sub-Saharan African researchers is important for the generation and transfer of health technology assessment (HTA) evidence, in order to support priority-setting in health. The objective of this analysis was to evaluate collaboration patterns between countries. We conducted a rapid evidence assessment that included a random sample of health economic evaluations carried out in 20 countries (Angola, Botswana, Congo, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, Ghana, Kenya, Nigeria, Ethiopia, Uganda). We conducted bibliometric network analysis based on all first authors with a Sub-Saharan African academic affiliation and their co-authored publications ("network-articles"). Then we produced a connection map of collaboration patterns among Sub-Saharan African researchers, reflecting the number of network-articles and the country of affiliation of the main co-authors. The sample of 119 economic evaluations mostly related to treatments of communicable diseases, in particular HIV/AIDS (42/119, 35.29 %) and malaria (26/119, 21.85 %). The 39 first authors from Sub-Saharan African institutions together co-authored 729 network-articles. The network analysis showed weak collaboration between health economic researchers in Sub-Saharan Africa, with researchers being more likely to collaborate with Europe and North America than with other African countries. South Africa stood out as producing the highest number of health economic evaluations and collaborations. The development and evaluation of HTA research networks in Sub-Saharan Africa should be supported, with South Africa central to any such efforts. Organizations and institutions from high income countries interested in supporting priority setting in Sub-Saharan Africa should include promoting collaboration as part of their agendas, in order to take advantage of the potential transferability of results and methods of the

AbstractChildren living in homes with livestock may have both an increased risk of enteric infections and improved access to food, and therefore improved nutritional status. Few studies, however, have characterized these relationships in tandem. This study investigated the association between child health and household ownership of livestock. A cross-sectional study was performed using data from Demographic and Health Surveys conducted in 30 sub-Saharan African countries with 215,971 rural children under 5 years of age from 2005 to 2015. Logistic regression was performed for each country to estimate the relationship between a log 2 increase in the number of livestock owned by the household and three child-health outcomes: 2-week prevalence of diarrhea, stunting, and all-cause mortality. Results for each country were combined using meta-analyses. Most countries (22 of 30) displayed an odds ratio (OR) less than 1 for child stunting associated with livestock (pooled OR = 0.97; 95% confidence interval [CI] = 0.95, 0.99). The results for diarrhea were more even with 14 countries displaying ORs greater than 1 and 10 displaying ORs less than 1. Most countries (22 of 30) displayed an OR greater than 1 for child mortality (pooled OR = 1.04; 95% CI = 1.02, 1.06). All meta-analyses displayed significant heterogeneity by country. Our analysis is consistent with the theory that livestock may have a dual role as protective against stunting, an indicator of chronic malnutrition, and a risk factor for all-cause mortality in children, which may be linked to acute infections. The heterogeneity by country, however, indicates more data are needed on specific household livestock management practices.

Built environment and policy interventions are effective strategies for controlling the growing worldwide deaths from physical inactivity-related non-communicable diseases. To improve built environment research and develop African specific evidence, it is important to first tailor built environment measures to African contexts and assess their psychometric properties across African countries. This study reports on the adaptation and test-retest reliability of the Neighborhood Environment Walkability Scale in seven sub-Saharan African countries (NEWS-Africa). The original NEWS comprising 8 subscales measuring reported physical and social attributes of neighborhood environments was systematically adapted for Africa through extensive input from physical activity and public health researchers, built environment professionals, and residents in seven African countries: Cameroon, Ghana, Kenya, Mozambique, Nigeria, South Africa and Uganda. Cognitive testing of NEWS-Africa was conducted among diverse residents (N = 109, 50 youth [12 - 17 years] and 59 adults [22 - 67 years], 69 % from low socioeconomic status [SES] neighborhoods). NEWS-Africa was translated into local languages and evaluated for 2-week test-retest reliability in adult participants (N = 301; female = 50.2 %; age = 32.3 ± 12.9 years) purposively recruited from neighborhoods varying in walkability (high and low walkable) and SES (high and low income) and from villages in six of seven participating countries. The original 67 NEWS items was expanded to 89 scores (76 individual NEWS items and 13 computed scales). Several modifications were made to individual items, and some new items were added to capture important attributes in the African environment. A new scale on personal safety was created, and the aesthetics scale was enlarged to reflect African specific characteristics. Over 95 % of all NEWS-Africa scores (items plus computed scales) demonstrated evidence of "excellent" (ICCs�

The present study provides evidence to support enhanced attention to reproductive health and comprehensive measures to increase access to quality reproductive health services. We compare and contrast the financing and utilization of reproductive health services in six sub-Saharan African countries using data from National Health Accounts and Demographic and Health Surveys. Spending on reproductive health in 2006 ranged from US$4 per woman of reproductive age in Ethiopia to US$17 in Uganda. These are below the necessary level for assuring adequate services given that an internationally recommended spending level for family planning alone was US$16 for 2006. Moreover, reproductive health spending shows signs of decline in tandem with insufficient improvement in service utilization. Public providers played a predominant role in antenatal and delivery care for institutional births, but home deliveries with unqualified attendants dominated. The private sector was a major supplier of condoms, oral pills and IUDs. Private clinics, pharmacies and drug vendors were important sources of STI treatment. The findings highlight the need to commit greatly increased funding for reproductive health services as well as more policy attention to the contribution of public, private and informal providers and the role of collaboration among them to expand access to services for under-served populations.

2015-06-01

The President's Emergency Plan for AIDS Relief (PEPFAR) has provided billions of US tax dollars to expand HIV treatment, care, and prevention programs in sub-Saharan Africa. This investment has generated significant health gains, but much less is known about PEPFAR's population-level economic effects. We used a difference-in-differences approach to compare employment trends between ten countries that received a large amount of PEPFAR funding (focus countries) and eleven countries that received little or no funding (control countries). We found that PEPFAR was associated with a 13 percent differential increase in employment among males in focus countries, compared to control countries. However, we observed no change in employment among females. In addition, we found that increasing PEPFAR per capita funding by $100 was associated with a 9.1-percentage-point increase in employment among males. This rise in employment generates economic benefits equal to half of PEPFAR's cost. These findings suggest that PEPFAR's economic impact should be taken into account when making aid allocation decisions. Project HOPE—The People-to-People Health Foundation, Inc.

How dietary intake has been assessed in African countries? A systematic review.

Science.gov (United States)

Vila-Real, Catarina; Pimenta-Martins, Ana; Gomes, Ana Maria; Pinto, Elisabete; Maina, Ndegwa Henry

2018-04-13

Dietary patterns are often considered as one of the main causes of non-communicable diseases worldwide. It is of utmost importance to study dietary habits in developing countries since this work is scarce. To summarize the most recent research conducted in this field in African countries, namely the most used methodologies and tools. A systematic review was conducted on MEDLINE®/PubMed, aiming to identify scientific publications focused on studies of dietary intake of different African populations, in a ten-year period. Papers not written in English/Portuguese/Spanish, studies developed among African people but not developed in African countries, studies aiming to assess a particular nutrient/specific food/food toxin and studies that assessed dietary intake among children were excluded. Out of 99 included studies, the 24-hour recall and the food-frequency questionnaire were the most used dietary intake assessment tools, used to assess diet at an individual level. It was also observed that often country-unspecific food composition databases are used, and the methodologies employed are poorly validated and standardized. There is an emergent need to improve the existing food databases by updating food data and to develop suitable country-specific databases for those that do not have their own food composition table.

Crocker-Buque, Tim; Pollock, Allyson M

2015-02-01

To critically appraise the quality of sub-Saharan African cancer registration systems that submitted data to GLOBOCAN 2008 with respect to population coverage using publicly available information and to show the use of GLOBOCAN statistics in determining global health priorities. Sources of cancer registration data for twenty-six sub-Saharan African cancer registries were identified from GLOBOCAN 2008 factsheets. Additional information was extracted from International Agency for Research on Cancer publications. A literature search was conducted to identify studies that reported additional information on data collection methods and provided 27 studies. The websites of the 10 largest funders of development assistance for health were searched for GLOBOCAN citations. Twenty-six sub-Saharan African cancer registration systems submitting data to GLOBOCAN 2008 in relation to 21 countries. Information on 15 quality variables were extracted and compared with the international gold standard for cancer registration systems. Population coverage of the cancer registries ranged from from 2.3% of the population in Kenya to 100% in The Gambia, with a heavy urban bias in all countries. However, 20 countries (300 million people) had no cancer registration systems. Nineteen of the 26 registries failed to meet more than five of the 15 quality criteria and only one country met more than 10. Seven of the 10 largest funders of development assistance for health cite GLOBOCAN statistics in support of policy priorities. GLOBOCAN 2008 estimates are based on data drawn from poor quality cancer registration systems, with limited or no population registry coverage. It is essential the GLOBOCAN 2012 estimates should provide information on the quality of the data collection and explain the limitations of the estimates. Development organisations and the World Health Organization need to take a more cautious approach when using these data to determine priorities and allocating resources. © The

Determinants of Adherence to Antiretroviral Therapy among HIV-Infected Patients in Africa

Directory of Open Access Journals (Sweden)

Ayalu A. Reda

2012-01-01

Full Text Available Background. There are only a few comprehensive studies of adherence to ART and its challenges in Africa. This paper aims to assess the evidence on the challenges and prospects of ART adherence in sub-Saharan Africa. Methods. The authors reviewed original and review articles involving HIV-positive individuals that measured adherence to ART and its predictors in the past decade. Findings. Against expectations, sub-Saharan Africa patients have similar or higher adherence levels compared to those of developed countries. The challenges to ART adherence include factors related to patients and their families, socioeconomic factors, medication, and healthcare systems. Conclusion. Despite good adherence and program-related findings, antiretroviral treatment is challenged by a range of hierarchical and interrelated factors. There is substantial room for improvement of ART programs in sub-Sahara African countries.

Climate change and global warming: implications for sub-Saharan Africa

Energy Technology Data Exchange (ETDEWEB)

Christian, E.

2010-07-01

The study reviews the potential threats of climate change in sub-Sahara Africa. It paints a picture of how the major green house gases (GHGs) -- CO{sub 2}, CH{sub 4} -- will grow in the sub-continent before the year 2015. The study also highlights the potential causes of climate change in the sub-continent based on anthropogenic and physical factors. It further examined the impacts of climate change in the sub-region based on the sensitivity, vulnerability and adaptations opened to the sub-region. Observation shows that overall social and economic activities in sub-Sahara Africa will be substantially worse than in any other developing world. Consequently, mitigation and adaptation measures were suggested to alleviate the impacts of climate change in the sub-region.

Resource Geopolitics: Cold War Technologies, Global Fertilizers, and the Fate of Western Sahara.

Science.gov (United States)

Camprubí, Lino

2015-07-01

When, after years of geological and geophysical exploration, a phosphate mine was discovered at Bu-Craa in 1964, Western Sahara received renewed geopolitical attention. Several countries competing for the control of the world fertilizer market, including Morocco, Spain, France, and the United States, developed diverging strategies to gain control of the mineral. After intense negotiations revolving around the materiality of mining technologies and involving reserve estimations, sabotage, and flexing of diplomatic muscles, Morocco took over the Spanish colony in 1975. While this secured Morocco's place in the world market, it condemned the local population to exile and domination. This article explores three technological stages of the exploitation of phosphate in Western Sahara that underpin the geopolitical history. This perspective yields new visions of cold war technology and postcolonial markets.

This paper employs a number of panel methodological approaches to explore the link between per capita carbon dioxide emissions, per capita real income, renewable energy consumption and health expenditures for a panel of 42 sub-Saharan African countries, spanning the period 1995-2011. The empirical findings provide supportive of a long-run relationship among the variables. Granger causality reveals the presence of a short-run unidirectional causality running from real GDP to CO2 emissions, a b...

Mental health of sub-saharan african migrants: The gendered role of migration paths and transnational ties

Directory of Open Access Journals (Sweden)

Julie Pannetier

2017-12-01

Full Text Available In Europe, migrants are at higher risk of common mental disorders or psychological distress than are natives. Little is known regarding the social determinants of migrant mental health, particularly the roles played by migration conditions and transnational practices, which may manifest themselves in different ways for men and for women. The goal of this paper was to understand the gendered roles of migration paths and transnational ties in mental health among sub-Saharan African migrants residing in the Paris, France, metropolitan area. This study used data from the Parcours study conducted in 2012–2013, which employed a life-event approach to collect data from a representative sample of migrants who visited healthcare facilities (n = 2468. We measured anxiety and depressive symptoms at the time of data collection with the Patient Health Questionnaire-4 (PHQ-4. Reasons for migration, the living conditions in the host country and transnational ties after migration were taken into account by sex and after adjustment. Our study demonstrates that among sub-Saharan African migrants, mental health is related to the migratory path and the migrant’s situation in the host country but differently for women and men. Among women, anxiety and depressive symptoms were strongly related to having left one’s home country because of threats to one’s life. Among men, residing illegally in the host country was related to impaired mental health. For both women and men, cross-border separation from a child less than 18 years old was not independently associated with anxiety and depressive symptoms. In addition, social and emotional support from relatives and friends—both from the society of origin and of destination—were associated with lower anxiety and depressive symptoms. Migrant mental health may be impaired in the current context of anti-migrant policies and an anti-immigrant social environment in Europe.

Insurance market development: An empirical study of African countries

Directory of Open Access Journals (Sweden)

Athenia Bongani Sibindi

2015-12-01

Full Text Available The insurance industry plays a very crucial role in an economy by fostering intermediation and by its mechanism of risk bearing. As such it could be argued that the insurance industry fosters economic growth. In this article we analyse the global insurance market development trends, particularly focusing on Africa. Our sample comprise of the 10 African countries namely—South Africa, Angola, Nigeria, Kenya, Mauritius, Namibia, Algeria, Tunisia, Morocco and Egypt. We employ three insurance market development metrics namely; premium volumes, insurance density and insurance penetrations ratios to establish trends in the level of development of global insurance markets. Our results document that the African countries (excluding South Africa have the least developed insurance markets. For most of the countries in our sample, the non-life insurance industry dominates the life-insurance industry. As such, it is imperative that their respective governments put in place measures that will grow their economies inorder to stimulate the development of insurance markets in Africa.

changes in the sub-Saharan African region as a whole and in some of the case countries in particular. Political leadership has changed in Ghana and Cote d'Ivoire with some course corrections in Ghana's health plans. Health sector financing in the region has become more dependent on external donors. The World Bank leads the external donor community in promoting policy-based lending. The complexity of a number of health problems has changed while the problems themselves remain the same as before. Essentially, building viable public health infrastructures to address basic public health needs must still be high on the agenda of action for most governments in the region. Thus, notwithstanding some course corrections and reasonable shifts in priorities, all the PHC principles are still applicable, indeed, much needed in the sub-Saharan African region. This study's findings, underscoring the fact that significant improvements in health are possible even where financial resources are limited, still hold true.

Cost Effective Ways of Implementing Nuclear Power Programme in African Countries

International Nuclear Information System (INIS)

Aderojua, Abraham; Choi, Kwang Sik

2011-01-01

1.1 Energy Poverty Energy Poverty is a term for a lack of access to electricity, heat or other forms of power. This more than often refers to the situation of peoples in the developing world. According to the records of the International Energy Agency (IEA), a detailed country-by-country database estimated that in 2009 the number of people without access to electricity was 1.4 billion or 20% of the world's population. Some 85% of those people live in rural areas. According to, current forecasts suggest the world will see an increase in global energy consumption of over 50% by 2030 with 70% of this growth in demand expected to come from developing countries. There is therefore the need to seek for a way of meeting this need within the time frame and doing so at an affordable price or rather with the most efficient allocation of resources. Nuclear energy can play a role in providing increased access to affordable energy in many parts of the world. There are growing concerns all over the world about energy security. This is partially due to the instability in the price of fossil fuel and to the political instability of most of the oil rich regions of the world. There arises therefore a need for means of meeting the increasingly growing energy demands of the nations while cutting down on the release of greenhouse gases into the atmosphere. 1.2 The African Situation Presently, the only country on the African continent that has operational nuclear power plants is South Africa. South Africa has two nuclear power plants. Koeberg- 1 and Koeberg-2. Koeberg-1 started operation in 1984 and Koeberg-2 in 1985. Both are 900 MW(e) PWRs. The remaining nations across Africa are dependent largely on either hydro power plants, thermal or gas or a combination of both. However, there has been an increase in interest in nuclear electricity in a number of African countries. The list includes countries like Algeria, Egypt, Nigeria, Namibia, e.tc. These are countries whose economies are

The impact of family planning on primary school enrolment in sub-national areas within 25 African countries.

Science.gov (United States)

Longwe, Abiba; Smits, Jeroen

2013-06-01

We study how the availability and use of family planning services in African countries influences the family planning situation of households and through this the educational participation of young children. A district panel dataset is used for 441 urban and rural areas within 233 districts of 25 countries. Path analysis shows that a decrease in the number of births is associated with an increase in educational participation in the area. The number of births is negatively associated with acceptance, knowledge and actual use of contraceptives in the area. As reversed causality and selection bias seem unlikely, the identified relationship probably is at least partially causal. Hence, investments in family planning services in poor areas are not only important because they allow women to plan their births better, but also because they may lead to higher primary enrolment rates and thus contribute to the region's future economic growth.

Several studies of environmental samples indicate that the levels of many persistent organic pollutants (POPs) are increasing in Africa, but few studies have been conducted in humans. Simultaneously, many African countries are experiencing a rapid economic growth and implementing information and communication technologies (ICT). These changes have generated high amounts of electronic waste (e-waste) that have not been adequately managed. We tested the hypothesis that the current levels of two main classes of POPs in Western and Central African countries are affected by the degree of socioeconomic development. We measured the levels of 36 POPs in the serum of recent immigrants (N=575) who came from 19 Sub-Saharan countries to the Canary Islands (Spain). We performed statistical analyses on their anthropometric and socioeconomic data. High median levels of POPs were found in the overall sample, with differences among the countries. Organochlorine pesticide (OCP) and polychlorinated biphenyl (PCB) levels increased with age. People from low-income countries had significantly higher OCP levels and much lower PCB levels than those from high-income countries. We found a significant association between the implementation of ICT and PCB contamination. Immigrants from the countries with a high volume of imports of second-hand electronic equipment had higher PCB levels. The economic development of Africa and the e-waste generation have directly affected the levels of POPs. The POP legacies of these African populations most likely are due to the inappropriate management of the POPs' residues. Copyright © 2014 Elsevier B.V. All rights reserved.

Wastage in the health workforce: some perspectives from African countries.

Science.gov (United States)

Dovlo, Delanyo

2005-08-10

Sub-Saharan Africa faces a human resources crisis in the health sector. Over the past two decades its population has increased substantially, with a significant rise in the disease burden due to HIV/AIDS and recurrent communicable diseases and an increased incidence of noncommunicable diseases. This increased demand for health services is met with a rather low supply of health workers, but this notwithstanding, sub-Saharan African countries also experience significant wastage of their human resources stock. This paper is a desk review to illustrate suggestions that the way human resources for health (HRH) are trained and deployed in Africa does not enhance productivity and that countries are unable to realize the full potential expected from the working life of their health workers. The paper suggests data types for use in measuring various forms of "wastage". "Direct" wastage--or avoidable increases in loss of staff through factors such as emigration and death--is on the rise, perhaps as a result of the HIV/AIDS epidemic. "Indirect" wastage--which is the result of losses in output and productivity from health professionals' misapplied skills, absenteeism, poor support and lack of supervision--is also common. HIV/AIDS represents a special cause of wastage in Africa. Deaths of health workers, fear of infection, burnout, absenteeism, heavy workloads and stress affect productivity. The paper reviews strategies that have been proposed and/or implemented. It suggests areas needing further attention, including: developing and using indicators for monitoring and managing wastage; enhancing motivation and morale of health workers; protecting and valuing the health worker with enhanced occupational safety and welfare systems; and establishing the moral leadership to effectively tackle HIV/AIDS and the brain drain.

Conflict and human African trypanosomiasis.

Science.gov (United States)

Berrang-Ford, Lea; Lundine, Jamie; Breau, Sebastien

2011-02-01

Human African Trypanosomiasis (HAT) has reemerged in sub-Saharan Africa as a disease of major public health importance. The success of HAT elimination in sub-Saharan Africa is subject to the feasibility of controlling, eliminating, or mitigating the determinants of incidence in affected countries. Conflict has been widely recognized and cited as a contributing factor to the resurgence of HAT in many countries, as well as to continuing HAT incidence in politically unstable and resource-poor regions. Despite extensive anecdotal and qualitative recognition of the role of conflict, there has been no quantitative research of this topic at the population level in affected African countries. We characterize the qualitative and quantitative associations between HAT incidence and conflict-related processes in HAT-affected African countries over the past 30 years. HAT and conflict-related data were collected for 35 affected countries in sub-Saharan Africa for the years 1976-2004. Descriptive and univariate inferential statistics, as well as negative binomial regression modeling, are used to assess the associations between HAT and conflict. A space-time scan statistic is used to identify significant incidence clusters. Clusters of HAT incidence over the past 30 years have predominantly coincided with periods of conflict or socio-political instability. HAT cases occurred significantly more often in countries and during years with conflict, high political terror, and internationalized civil war. The results indicate a lag period between the start of conflict events and a peak in incidence of approximately 10 years. We recommend explicit consideration and quantification of socio-political measures such as conflict and terror indices in GIS (Geographic Information Systems)-based risk assessments for HAT policy and intervention.

Full Text Available Most of the countries of sub-Saharan Africa belong to the most underdeveloped and poorest countries in the world economy. This region consists of forty-nine countries but at world GDP, world export, world import and inflow of foreign direct investment share only by small percent. There are some positive facts in the recent history of sub- Saharan Africa. Sub-Saharan Africa has grown faster than the world economy in the past ten years. The predictions are also positive. There is an expectation of another growth till the 2020. If the sub-Saharan countries want to keep the growth in the future they have to invest to infrastructure, in educational system, in research and science to make their economies more competitive.

Population Genomics of sub-saharan Drosophila melanogaster: African diversity and non-African admixture.

Directory of Open Access Journals (Sweden)

John E Pool

Full Text Available Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved. We report the genome sequencing of 139 wild-derived strains of D. melanogaster, representing 22 population samples from the sub-Saharan ancestral range of this species, along with one European population. Most genomes were sequenced above 25X depth from haploid embryos. Results indicated a pervasive influence of non-African admixture in many African populations, motivating the development and application of a novel admixture detection method. Admixture proportions varied among populations, with greater admixture in urban locations. Admixture levels also varied across the genome, with localized peaks and valleys suggestive of a non-neutral introgression process. Genomes from the same location differed starkly in ancestry, suggesting that isolation mechanisms may exist within African populations. After removing putatively admixed genomic segments, the greatest genetic diversity was observed in southern Africa (e.g. Zambia, while diversity in other populations was largely consistent with a geographic expansion from this potentially ancestral region. The European population showed different levels of diversity reduction on each chromosome arm, and some African populations displayed chromosome arm-specific diversity reductions. Inversions in the European sample were associated with strong elevations in diversity across chromosome arms. Genomic scans were conducted to identify loci that may represent targets of positive selection within an African population, between African populations, and between European and African populations. A disproportionate number of candidate selective sweep regions were located near genes with varied roles in gene regulation.

The Digital Divide prevents Africa from taking advantages of new information technologies. One of the most urgent priorities is to bring the Internet in African Universities, Research, and Learning Centers to the level of other regions of the world. eGY-Africa, and the Sharing Knowledge Foundation are two bottom-up initiatives by scientists to secure better cyber-infrastructure and Internet facilities in Africa. Recommendations by the present scientific communities are being formulated at national, regional and international levels. The Internet capabilities are well documented at country level overall, but this is not the case at the University level. The snapshot of the Internet status in universities in 17 African countries, obtained by a questionnaire survey, is consistent with measures of Internet penetration in the corresponding country. The monitoring of Internet performance has been proposed to those African universities to provide an information base for arguing the need to improve the coverage for Africa. A pilot program is recommended that will start scientific collaboration with Europe in western Africa using ICT. The program will lay the foundations for the arrival of new technologies like Grids.

As an innovative solution to poor access to care in low- and middle-income countries (LMICs), m-health has gained wide attention in the past decade. Despite enthusiasm from the global health community, LMICs have not demonstrated high uptake of m-health promoting policies or public investment. To benchmark the current status, this study compared m-health policy readiness scores between sub-Saharan Africa and high-income Organization for Economic Cooperation and Development (OECD) countries using an independent two-sample t test. In addition, the enabling factors associated with m-health policy readiness were investigated using an ordinal logistic regression model. The study was based on the m-health policy readiness scores of 112 countries obtained from the World Health Organization Third Global Survey on e-Health. The mean m-health policy readiness score for sub-Saharan Africa was statistically significantly lower than that for OECD countries (p = 0.02). The enabling factors significantly associated with m-health policy readiness included information and communication technology development index (odds ratio [OR] 1.57; 95% confidence interval [CI] 1.12-2.2), e-health education for health professionals (OR 4.43; 95% CI 1.60-12.27), and the location in sub-Saharan Africa (OR 3.47; 95% CI 1.06-11.34). The findings of our study suggest dual policy goals for m-health in sub-Saharan Africa. First, enhance technological and educational support for m-health. Second, pursue global collaboration for building m-health capacity led by sub-Saharan African countries with hands-on experience and knowledge. Globally, countries should take a systematic and collaborative approach in pursuing m-health policy with the focus on technological and educational support.

Global potential for carbon sequestration. Geographical distribution, country risk and policy implications

We have provided a framework for identifying least-cost sites for afforestation and reforestation and deriving carbon sequestration cost curves at a global level in a scenario of limited information. Special attention is given to country risk in developing countries and the sensitivity to spatial datasets. Our model results suggest that within 20 years and considering a carbon price of USD 50/tC, tree-planting activities could offset 1 year of global carbon emissions in the energy sector. However, if we account for country risk considerations-associated with political, economic and financial risks - carbon sequestration is reduced by approximately 60%. With respect to the geography of supply, illustrated by grid-scale maps, we find that most least-cost sites are located in regions of developing countries such as the Sub-Sahara, Southeast Brazil and Southeast Asia.

Natural disasters in African countries: what can we learn about them?

Directory of Open Access Journals (Sweden)

M T Lukamba

2010-03-01

Full Text Available Problems posed by disasters have become increasingly important for all African governments. Every year a variety of disas ters occurs in Sub-Saharan Africa and these are becoming more prevalent. This article presents an analysis of statistical surveys for natural disasters in different regions of Africa over a 30-year period from 1974 to 2003. It shows that disaster frequency is increasing on the continent. The investigation of the data demonstrates that the East Africa region is under the greatest threat from natural disasters. In 2008, climatological disasters, notably droughts, claimed many victims in the eastern part of Africa, with more than one third of the population affected in Djibouti, Eritrea, and Somalia. The region has experienced the highest recorded number of disaster events for the past 30 years, followed by the West Africa region. The Southern Africa region is placed third as far as the frequency of disaster events in sub-Saharan Africa is concerned. The least disaster prone region is central Africa. The observations made in this analysis relate to the economic losses in different regions from the impact of natural disasters. In some instances, recovery from economic loss could not be recouped because of stunted growth and other internal problems in these countries. In addition, this article suggests some strategies to mitigate the problem of natural hazards in sub-Saharan Africa.

The state, refugees and migration in sub-Saharan Africa.

Science.gov (United States)

Akokpari, J K

1998-01-01

Migration and refugee movements could significantly decline in sub-Saharan African countries. However, countries must redistribute meager resources equitably and engage in environmental protection. Refugee and migrant populations have increased in sub-Saharan Africa during 1969-95, from 700,000 to 6.8 million. This study examined the causes of migration and the implications for host countries. Doornbos (1990) identifies the root problem as the partisan nature of African politics and the incapacity to manage ecological degradation. The African state is wholly or partially responsible for the creation of conflicts. Examples abound in Zaire, South Africa, Sudan, Rwanda, Burundi, Somalia, Ethiopia, Liberia, Congo, and Chad. State partisanship is also evident in Angola, Mozambique, Uganda, and Sierra Leone. An estimated 10 million Africans, in 1985, left their homes due to wars, government repression, or the inability of land to support them. In 1994, USAID estimated that 11.6 million Africans in 10 countries were threatened by famine from drought. Environmental degradation has generated conflicts. Africa's marginalized economy results in recession, unemployment, inflation, and distributional conflicts. Democratization has brought conflicts between the state, civil society, and exiles. Refugees face homelessness, poverty, emotional distress, inadequate food, and disease. Host countries face security threats, pressure on limited resources, rebellions from refugees and their involvement with foreign mercenaries, local conflicts between native and refugee populations, and environmental degradation from refugees.

Wastage in the health workforce: some perspectives from African countries

North Africa is a key region for understanding human history, but the genetic history of its people is largely unknown. We present genomic data from seven 15,000-year-old modern humans, attributed to the Iberomaurusian culture, from Morocco. We find a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East. We do not find evidence for gene flow from Paleolithic Europeans to Late Pleistocene North Africans. The Taforalt individuals derive one-third of their ancestry from sub-Saharan Africans, best approximated by a mixture of genetic components preserved in present-day West and East Africans. Thus, we provide direct evidence for genetic interactions between modern humans across Africa and Eurasia in the Pleistocene.

The Finance Growth Link: Comparative Analysis of Two Eastern African Countries

Directory of Open Access Journals (Sweden)

Fanta Ashenafi Beyene

2016-09-01

Full Text Available This paper examines the finance growth link of two low-income Sub-Saharan African economies – Ethiopia and Kenya – which have different financial systems but are located in the same region. Unlike previous studies, we account for the role of non-bank financial intermediaries and formally model the effect of structural breaks caused by policy and market-induced economic events. We used the Vector Autoregressive model (VAR, conducted impulse response analysis and examined variance decomposition. We find that neither the level of financial intermediary development nor the level of stock market development explains economic growth in Kenya. For Ethiopia, which has no stock market, intermediary development is found to be driven by economic growth. Three important inferences can be made from these findings. First, the often reported positive link between finance and growth might be caused by the aggregation of countries at different stages of economic growth and financial development. Second, country-specific economic situations and episodes are important in studying the relationship between financial development and economic growth. Third, there is the possibility that the econometric model employed to test the finance growth link plays a role in the empirical result, as we note that prior studies did not introduce control variables.

The genetic impact of the lake chad basin population in North Africa as documented by mitochondrial diversity and internal variation of the L3e5 haplogroup.

Science.gov (United States)

Podgorná, Eliška; Soares, Pedro; Pereira, Luísa; Cerný, Viktor

2013-11-01

The presence of sub-Saharan L-type mtDNA sequences in North Africa has traditionally been explained by the recent slave trade. However, gene flow between sub-Saharan and northern African populations would also have been made possible earlier through the greening of the Sahara resulting from Early Holocene climatic improvement. In this article, we examine human dispersals across the Sahara through the analysis of the sub-Saharan mtDNA haplogroup L3e5, which is not only commonly found in the Lake Chad Basin (∼17%), but which also attains nonnegligible frequencies (∼10%) in some Northwestern African populations. Age estimates point to its origin ∼10 ka, probably directly in the Lake Chad Basin, where the clade occurs across linguistic boundaries. The virtual absence of this specific haplogroup in Daza from Northern Chad and all West African populations suggests that its migration took place elsewhere, perhaps through Northern Niger. Interestingly, independent confirmation of Early Holocene contacts between North Africa and the Lake Chad Basin have been provided by craniofacial data from Central Niger, supporting our suggestion that the Early Holocene offered a suitable climatic window for genetic exchanges between North and sub-Saharan Africa. In view of its younger founder age in North Africa, the discontinuous distribution of L3e5 was probably caused by the Middle Holocene re-expansion of the Sahara desert, disrupting the clade's original continuous spread. © 2013 John Wiley & Sons Ltd/University College London.

Many of these migrants are women who have a precarious legal status and can no longer reach Europe, whose borders have been considerably securitized since September 11, 2001. They also have no wish to risk their lives again returning south across the Sahara Desert. This paper discusses the results of an exploratory research project conducted in Morocco on the relationships between the sub-Saharan migrant women's traumatic experiences, social invisibility, and emotional distress in the context of a massive securitization of Euro-Mediterranean borders.

Information and Communication Technologies and Poverty Reduction in Developing Countries : the Case of Sub Saharan Africa countries

Full Text Available There is a growing interest in using Information and Communication Technologies (ICTs to support poverty reduction efforts and strategies in the framework of the Millennium Development Goals (MDGs. These interest ended up revealing how much the Poverty Reduction Strategy Papers (PRSPs of many african nations have underestimated the importance of ICTs as a development tool. The fact that so little was mentionned about the use of ICTs for poverty alleviation and creation of employment highlighted the confusion, and uncertainty of decision makers. At the country level, ICT is still to be effectively integrated into national poverty alleviation and development strategies. The question then is how ICTs can help achieve those objectives. How can ICTs be used as tools to fight against poverty? Poverty is widely recognized as multidimensional, encompassing food security, health, education, rights, security and dignity, amongst others as stressed by Bachelor and al in a model showing the intricate linkages between ICTs and most PRSP goals. The link between ICTs and poverty reduction strategy is therefore not that obvious. Although, researchers and development partners involved in poverty alleviation recognize more easily the linkage between ICT and poverty reduction strategies. In any case, it is a prerequisite to have a conducive environment and country readiness for ICTs implementation. Unfortunately, in many Sub-Saharan Africa countries, there is not yet a clear and effective policy and strategy for the use of ICT.

It is unknown whether resources necessary to implement the Surviving Sepsis Campaign guidelines and sepsis bundles are available in Africa. This self-reported, continent-wide survey compared the availability of these resources between African and high-income countries, and between two African regions (Sub-Sahara Africa vs. South Africa, Mauritius and the Northern African countries). The study was conducted as an anonymous questionnaire-based, cross-sectional survey among anaesthesia providers attending a transcontinental congress. Based on the respondents' country of practice, returned questionnaires were grouped into African and high-income countries. The questionnaire contained 74 items and evaluated all material resources required to implement the most recent Surviving Sepsis Campaign guidelines. Group comparisons were performed with the Chi2, Fisher's Exact or Mann Whitney U test, as appropriate. The overall response rate was 74.3% (318/428). Three-hundred-seven questionnaires were analysed (African countries, n = 263; high-income countries, n = 44). Respondents from African hospitals were less likely to have an emergency room (85.5 vs. 97.7%, P = 0.03) or intensive care unit (73.8 vs. 100%, P resources available to implement the Surviving Sepsis Campaign guidelines in entirety. The percentage of implementable recommendations was lower in African than in high-income countries (72.6 (57.7 to 87.7)% vs. 100 (100 to 100)%, P resources to implement the majority of strong Surviving Sepsis Campaign recommendations and the sepsis bundles may allow modification of current sepsis guidelines based on available resources and implementation of a substantial number of life-saving interventions into sepsis care in Africa.

HIV-related stigma hampers treatment and prevention efforts worldwide. Effective interventions to counter HIV-related stigma are greatly needed. Although the "contact hypothesis" suggests that personal contact with persons living with HIV (PLHIV) may reduce stigmatizing attitudes in the general population, empirical evidence in support of this hypothesis is lacking. Our aim was to estimate the association between personal contact with PLHIV and HIV-related stigma among the general population of sub-Saharan Africa. Social distance and anticipated stigma were operationalized using standard HIV-related stigma questions contained in the Demographic and Health Surveys and AIDS Indicator Surveys of 26 African countries between 2003 and 2008. We fitted multivariable logistic regression models with country-level fixed effects, specifying social distance as the dependent variable and personal contact with PLHIV as the primary explanatory variable of interest. We analyzed data from 206,717 women and 91,549 men living in 26 sub-Saharan African countries. We estimated a statistically significant negative association between personal contact with PLHIV and desires for social distance (adjusted odds ratio [AOR] = 0.80; p  interventions should be developed and tested to reduce the stigma of HIV.

To estimate the lost investment of domestically educated doctors migrating from sub-Saharan African countries to Australia, Canada, the United Kingdom, and the United States. Human capital cost analysis using publicly accessible data. Sub-Saharan African countries. Nine sub-Saharan African countries with an HIV prevalence of 5% or greater or with more than one million people with HIV/AIDS and with at least one medical school (Ethiopia, Kenya, Malawi, Nigeria, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe), and data available on the number of doctors practising in destination countries. The financial cost of educating a doctor (through primary, secondary, and medical school), assuming that migration occurred after graduation, using current country specific interest rates for savings converted to US dollars; cost according to the number of source country doctors currently working in the destination countries; and savings to destination countries of receiving trained doctors. In the nine source countries the estimated government subsidised cost of a doctor's education ranged from $21,000 (£13,000; €15,000) in Uganda to $58,700 in South Africa. The overall estimated loss of returns from investment for all doctors currently working in the destination countries was $2.17bn (95% confidence interval 2.13bn to 2.21bn), with costs for each country ranging from $2.16m (1.55m to 2.78m) for Malawi to $1.41bn (1.38bn to 1.44bn) for South Africa. The ratio of the estimated compounded lost investment over gross domestic product showed that Zimbabwe and South Africa had the largest losses. The benefit to destination countries of recruiting trained doctors was largest for the United Kingdom ($2.7bn) and United States ($846m). Among sub-Saharan African countries most affected by HIV/AIDS, lost investment from the emigration of doctors is considerable. Destination countries should consider investing in measurable training for source countries and strengthening of their

Full Text Available Is Africa’s current growth reducing inequality? What are the implications of growth on output performances in Africa? Does the effect of Africa’s growth on sectorial output have any implication for inequality in Africa? The study investigates the effect of shocks on a set of macroeconomic variables on inequality (measured by life expectancy and the implication of this on sectors that are perceived to provide economic empowerment in form of employment for people living in the African countries in our sample. Studies already find that growth in many African countries has not been accompanied with significant improvement in employment. Therefore inequality is subject to a counter cyclical trend in production levels when export destination countries experience a recession. The study also provides insight on the effect of growth on sectorial output for three major sectors in the African economy with the intent of analyzing the impact of growth on sectorial development. The method used in this study is Panel Vector Autoregressive (PVAR estimation and the obvious advantage of this method lies in the fact that it allows us to capture both static and dynamic interdependencies and to treat the links across units in an unrestricted fashion. Data is obtained from World Bank (WDI Statistics for the period 1985 to 2012 (28 years for 10 African Countries. Our main findings confirm strong negative relationship between GDP growth and life expectancy and also for GDP and the services and manufacturing sector considering the full sample.

Pluvial Phases In The Sahara During The Holocene: A Multi-disciplinary Comparison

Science.gov (United States)

Barnikel, F.; Becht, M.

The understanding of low latitude palaeoclimatic dynamics is incomplete without a thorough analysis of the wide-spread fluctuations between humid and arid phases in the Sahara. It is especially the holocene that has been scrutinized in respect to lake and river deposits, pollen analysis, macrorest analysis, groundwater dating, remote sensing, pedology, archaeology and even glottochronology. During the last decades a lot of teams from different countries (e.g. French in the west and south, Germans in the south and east, Americans, Italians and Polish in the east and many more) have evaluated numerous data gained from different disciplines all over the Sahara. Inten- sive work has shed new light on climate dynamics especially in the eastern part. But even there, as in other parts as well, the data are insufficient to explain palaeoclimatic variability to a satisfying degree. Meticulous analysis of the published data has shown grave inconsistencies between the different disciplines concerning dates for pluvial phases (differences up to several millenia), the intensity of rainfall, the face of the palaeoenvironment and the like. Our aim is to show the areas that lack sufficient data and to point out the huge problems that arise from the differing research results in other parts. Since a valid assessment of holocene palaeoclimatic dynamics for large parts of the globe is unthinkable without a proper understanding of emergence, form and ending of pluvial phases in the Sahara, more multi-disciplinary work is neces- sary. Furthermore, all data, especially the radiocarbon datings, need to be collected and made accessible for all disciplines in a data bank.

Dry Deposition from Sahara Sources Regions of Western Africa

2014-01-01

Full Text Available Sahara dust storms during March 2004 have attracted much attention from the dust-research community due to their intensity, wide coverage, and endurance. In the present work, the dry deposition mechanisms of mineral dust are analysed during an event on the 3 March 2004 over the Northwest African coast. This particular case was chosen based on the strong dry removal that occurred, rendering it ideal for examining the deposition processes. The simulation of synoptic conditions and dry deposition of four dust particles including clay, small silt, large silt, and sand was performed with Eta model, coupled with a desert dust cycle module. The results have been compared with surface data from weather stations in North Africa, data of dry metals from stations located in Gran Canaria, and various satellite images such as European Organization for the Exploitation of Meteorological Satellites and Moderate Resolution Imaging Spectroradiometer for the period in question.

20th-Century Climate Change over Africa: Seasonal Variation in Hydroclimate Trends and Sahara Desert Extent

Science.gov (United States)

Nigam, S.; Thomas, N. P.

2017-12-01

Twentieth-century trends in seasonal temperature and precipitation over the African continent are analyzed from observational data sets and historical climate simulations. Given the agricultural economy of the continent, a seasonal perspective is adopted as it is more pertinent than an annual-average one which can mask off-setting but agriculturally-sensitive seasonal hydroclimate variations. Examination of linear trends in seasonal surface air temperature (SAT) shows that heat stress has increased in several regions, including Sudan and Northern Africa where largest SAT trends occur in the warm season. Broadly speaking, the northern continent has warmed more than the southern one in all seasons. Precipitation trends are varied but notable declining trends are found in the countries along the Gulf of Guinea, especially in the source region of Niger river in West Africa, and in the Congo river basin. Rainfall over the African Great Lakes - one of the largest freshwater repositories - has however increased. We show that the Sahara Desert has expanded significantly over the 20th century - by 12-20% depending on the season. The desert expanded southward in summer, reflecting retreat of the northern edge of the Sahel rainfall belt; and to the north in winter, indicating potential impact of the widening of the Tropics. Specific mechanisms driving the expansion in each season are investigated. Finally, this observational analysis is used to evaluate the state-of-the-art climate models from a comparison of the 20th-century hydroclimate trends with those manifest in historical climate simulations. The evaluation shows that modeling regional hydroclimate change over the Africa continent remains challenging.

A first contribution comments the situation of the African electricity sector by notably highlighting its paradoxes (huge available reserves but very low production capacities). The author proposes a brief overview and discussion of the present production capacities and supply, outlines production shortfalls and their main reasons, comments the situation of demand, consumption and markets by distinguishing three main geographical areas (Northern Africa, Southern Africa, and Central Africa) and indicating some data related to urban and rural electrification in different parts of Africa. He also addresses the issue of prices and costs. After having outlined these paradoxes and differences, he notices the weight of history, the fact that markets are too narrow and supported by too fragile economies, and the negative influence of political and economic failures. He proposes perspectives to introduce a sustainable growth of the African electricity sector. The second contribution proposes an analysis of the present situation in Sub-Saharan Africa and possibilities of action in the field of biomass. The author notably reports the case study of Bamako. The third contribution addresses the possibility of transformation of the African gas into electricity. He notably comments the leading and innovating projects in West-Africa: the West African Gas Pipeline (the first African gas project with a regional importance), the Mauritanian gas potential which could be a chance for the mining industry of this country and for neighbouring countries, the developments in Ivory Coast and Senegal. He gives an overview of projects in Central and Southern Africa: the Logbaba deposit in Cameroon, slow advances in the Republic of Congo, the challenge of methane development by the Kivu Lake, investments in Mozambique and Tanzania. The fourth contribution discusses challenges to be faced for energy projects (energy planning, hydrocarbons, renewable energies, electric energy) and for energy

Modelling a sustainability yardstick in modern energisation of rural sub-Saharan Africa

2007-01-01

The bulk of rural Africa (as well as much of the third world) remains un-electrified and is underserved or poorly served by any other form of modern energy infrastructure. In case of a deep sub-Sahara African country like Kenya it is often dismissively argued that lack of finance and appropriate technology are the obvious causes. This argument would however not hold when applied to the more technologically advanced South Africa where a whopping 50% of rural households still suffer a similar fate. The common perception is that in the presence of modern technology the desired social change process will automatically commence. Unfortunately (and possibly due to pressure from donors) typical post project reports from the third world often contain deliberate commissions or omissions that essentially belie the grim reality on the ground. What seems to lack is a well-defined yardstick or standard check-off list as to the essential attributes of a sustainable energy dissemination project. Problems in modern society are now largely tackled using a wide range of software applications. However even with all the well-tested skills in computer coding endless consumer complaints abound. 'Usability Engineering' is an example a state-of-the-art scientific tool that has been extensively used in recent times by the software design industry to tackle such problems as enhancement of the human/computer interface. This paper proposes that these modern scientific tools could be adopted to create a yardstick and break the intangible technological barrier to African rural modernization to better the lot of our communities

Biofuel Development Initiatives in Sub-Saharan Africa: Opportunities and Challenges

Directory of Open Access Journals (Sweden)

Patrick T. Sekoai

2016-06-01

Full Text Available In recent years, biofuels have emerged as a suitable alternative to hydrocarbon fuel due to their foreseen potential of being a future energy resource. Biofuel development initiatives have been successfully implemented in countries like Brazil, United States of America, European Union, Canada, Australia, and Japan. However, such programmes have been stagnant in Africa due to various constraints, such as financial barriers, technical expertise, land availability, and government policies. Nonetheless, some countries within the continent have realized the potential of biofuels and have started to introduce similar programmes and initiatives for their development. These include the bioethanol production initiatives and the plantation of jatropha oil seeds in most Sub-Saharan African countries for biodiesel production. Therefore, this paper examines the biofuel development initiatives that have been implemented in several countries across Sub-Saharan Africa over the past few years. It also discusses the opportunities and challenges of having biofuel industries in the continent. Finally, it proposes some recommendations that could be applied to accelerate their development in these Sub-Saharan African countries.

Immigrants' utilization of primary health care (PHC) services differs from that of the host populations. However, immigrants are often classified in broad groups by continent of origin, and the heterogeneity within the same continent may hide variation in use among immigrant groups at a national level. Differences in utilization of PHC between sub-Saharan African immigrants have not received much attention. Registry-based study using merged data from the National Population Register and the Norwegian Health Economics Administration. African immigrants and their descendants registered in Norway in 2008 (36,366 persons) where included in this study. Using χ 2 test and logistic regression models, we assessed the differences in the use of PHC, including general practitioner (GP) and emergency room (ER) services, and the distribution of morbidity burden for immigrants from Somalia, Ethiopia, Eritrea, and Gambia. For the analyses, we used the number of visits and medical diagnoses from each consultation registered by the physician. Among the total studied population, 66.1% visited PHC within 1 year. The diagnoses registered were similar for all four immigrants groups, regardless of country of origin. Compared to immigrants from Somalia, the age and sex adjusted odds ratios (OR) for use of GP were significantly lower for Ethiopians (OR 0.91; 0.86-0.97), Eritreans (OR 0.85; 0.79-0.91), and Gambians (OR 0.88; 0.80-0.97). Similarly, we also observed lower use of ER among Ethiopians (OR 0.88; 0.81-0.95), Eritreans (OR 0.56; 0.51-0.62) and Gambians (OR 0.81; 0.71-0.92). However, immigrants from Somalia reduced their use of PHC with longer duration of stay in Norway. Differences between groups persisted after further adjustment for employment status. Despite the similarities in diagnoses among the sub-Saharan African immigrant groups in Norway, their use of PHC services differs by country of origin and length of stay. It is important to assess the reasons for the differences

Chinsembu, Kazhila C

2015-12-01

Although the burden of malaria is decreasing, parasite resistance to current antimalarial drugs and resistance to insecticides by vector mosquitoes threaten the prospects of malaria elimination in endemic areas. Corollary, there is a scientific departure to discover new antimalarial agents from nature. Because the two antimalarial drugs quinine and artemisinin were discovered through improved understanding of the indigenous knowledge of plants, bioprospecting Sub-Saharan Africa's enormous plant biodiversity may be a source of new and better drugs to treat malaria. This review analyses the medicinal plants used to manage malaria in Sub-Saharan Africa. Chemical compounds with antiplasmodial activity are described. In the Sub-Saharan African countries cited in this review, hundreds of plants are used as antimalarial remedies. While the number of plant species is not exhaustive, plants used in more than one country probably indicate better antimalarial efficacy and safety. The antiplasmodial data suggest an opportunity for inventing new antimalarial drugs from Sub-Saharan-African flora. Copyright © 2015 Elsevier B.V. All rights reserved.

Evidence suggests that the developmentenhancingeffects of FDI are felt more highly in the developing economies, such as economies in Africa.However, FDI inflow to the developing economies has been very low. Using data generated from the AfricanDevelopment Indicators (ADI between 1980 and 2008 in econometric estimations, this paper finds thatgovernment policies (especially fiscal and monetary policies play significant roles in facilitating FDI inflow tothe African countries studied. The study thereby suggests an improved regulatory framework to make Africamore attractive to inflow of FDI.

Paleohydrology and paleoenvironments at Bir Sahara: Pleistocene lithostratigraphy and sedimentology in the southern Egyptian Sahara

Science.gov (United States)

Hill, Christopher L.; Schild, Romuald

2017-12-01

The Bir Sahara area contains a remarkable record of Middle and Late Pleistocene hydrologic and environmental conditions for Saharan North Africa, based on lithostratigraphic and sedimentologic evidence from basin-fill deposits. Some of the deposits contain Lower Paleolithic (Acheulean) or Middle Paleolithic artifacts that help to constrain their age, since Acheulian artifacts are assigned to the Middle Pleistocene, while Middle Paleolithic artifacts are limited to either the Middle or Late Pleistocene. Locality BS-14 is in the southern part of Bir Sahara, while localities E-88-15, E-88-2, BS-13, and BS-16 are situated in the south-central part of the deflational basin, closer to the present-day water-hole. Lowered groundwater conditions during arid intervals resulted in erosional topographic basins. These deflational basins were later filled with sediments associated with wetter hydrologic conditions. The oldest studied sedimentary sequence in the Bir Sahara depression (BS-14) contains in situ Acheulian artifacts. Acheulian handaxes are found in sands underlying carbonates that are interpreted as evidence of spring-fed pond and marsh environments during a Middle Pleistocene wet interval. At the E-88-15 locality, the stratigraphic sequence documents deposition in a possible perennial pond or small lake that varied in extent and depth and is associated with Middle Paleolithic artifacts. At E-88-12 and BS-13, lateral and vertical variations in the lithofacies of the basin-fill sediments provide additional records of changing hydrologic conditions during the Late Pleistocene. These hydrologic conditions appear to reflect variations in water-table levels related to groundwater recharge and, at times, local rains.

Despite the threat of violence to the health and rights of women yet, for many years, there has been a dearth of nationally comparable data on domestic violence in sub-Saharan Africa. This paper examines whether women from poor households are more likely to experience violence from husband/partner than other women who are from middle or rich households. Data for the study are derived from most recent DHS surveys of ever-married women age 15-49 in Cameroun(3,691), Kenya(4,336), Mozambique(5610), Nigeria (16,763), Zambia(3,010) and Zimbabwe(5,016) who participated in the questions on Domestic Violence Module. Bivariate analysis and Binary Logistic Regression Analysis are used to explore the linkage between household poverty-wealth and spousal violence while simultaneously controlling for confounding variables. The overall prevalence of any form of violence (physical, sexual or emotional) ranges from 30.5% in Nigeria to 43.4% in Zimbabwe; 45.3% in Kenya; 45.5% in Mozambique; 53.9% in Zambia and 57.6% in Cameroun. Both bivariate and multivariate analyses show that in two of the six countries -Zambia and Mozambique, experience of violence is significantly higher among women from non-poor (rich) households than those from other households (poor and middle). For Zimbabwe and Kenya, women from poor households are more likely to have ever experienced spousal violence than those from non-poor households. In the remaining two countries- Nigeria and Cameroun, women from the middle class are more likely to have ever suffered abuse from husband/partner than those from the poor and rich households. Our results thus show that similar measurements of household poverty-wealth have produced varying relationships with respect to experience of spousal violence in six sub-Saharan African countries. In other words, experience of violence cuts across all household poverty-wealth statuses and therefore may not provide enough explanations on whether household-poverty necessarily serves to

According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper ...

This study examines the social anxieties associated with HIV prevention in adolescents in three African countries (Nigeria, Kenya, and Zimbabwe). The subjects used in this study were black Africans in form 2 or grade 10 in public high schools (Nigeria, n = 387; Kenya, n = 274; Zimbabwe n = 313). Subjects responded to the 33 item AIDS Social Assertiveness Scale (ASAS). Data indicated similar factor structures for each of the three countries and included five factors. The combined sample factor intercorrelations were modestly but significantly correlated. The mean scores for each factor were compared, and ANOVA of the factors by country, by gender, and by interaction between country and gender were performed. The factor structures were very similar between countries, each including five factors that had similar themes: condom interactions, refusal of risk, confiding in significant others, contact with people with HIV/AIDS, and general assertiveness. These factor structures were also very similar to one found in previous studies of Australian adolescents on the ASAS. The Kenyan means for four of the five factors were significantly lower than those for Nigeria, and were also significantly lower than the Zimbabwean means for two of the five factors, suggesting that Kenyan students are less anxious about social situations related to HIV/AIDS than others. Significant variance was found for several factors due to gender, country, and the interaction between gender and country. These results have important implications for designing education programs. The similarities of anxieties regarding HIV/AIDS social situations suggest that these clusters of social barriers to reduction of HIV infection risk might form the basis of educational interventions, and that dimensions of HIV social anxieties are similar across countries.

Today, African pastoralists are found mainly in the Sahel/Savannah belt spanning 6,000 km from west to east, flanked by the Sahara to the north and tropical rainforests to the south. The most significant group among them are the Fulani who not only keep cattle breeds of possible West Eurasian ancestry, but form themselves a gene pool containing some paternally and maternally-transmitted West Eurasian haplogroups. We generated complete sequences for 33 mitogenomes belonging to haplogroups H1 and U5 (23 and 10, respectively), and genotyped 16 STRs in 65 Y chromosomes belonging to haplogroup R1b-V88. We show that age estimates of the maternal lineage H1cb1, occurring almost exclusively in the Fulani, point to the time when the first cattle herders settled the Sahel/Savannah belt. Similar age estimates were obtained for paternal lineage R1b-V88, which occurs today in the Fulani but also in other, mostly pastoral populations. Maternal clade U5b1b1b, reported earlier in the Berbers, shows a shallower age, suggesting another possibly independent input into the Sahelian pastoralist gene pool. Despite the fact that animal domestication originated in the Near East ∼ 10 ka, and that it was from there that animals such as sheep, goats as well as cattle were introduced into Northeast Africa soon thereafter, contemporary cattle keepers in the Sahel/Savannah belt show uniparental genetic affinities that suggest the possibility of an ancient contact with an additional ancestral population of western Mediterranean ancestry. © 2017 Wiley Periodicals, Inc.

Current and future availability of and need for human resources for sexual, reproductive, maternal and newborn health in 41 countries in Sub-Saharan Africa.

The WHO African region, covering the majority of Sub-Saharan Africa, faces the highest rates of maternal and neonatal mortality in the world. This study uses data from the State of the World's Midwifery 2014 survey to cast a spotlight on the WHO African region, highlight the specific characteristics of its sexual, reproductive, maternal and newborn health (SRMNH) workforce and describe and compare countries' different trajectories in terms of meeting the population need for services. Using data from 41 African countries, this study used a mathematical model to estimate potential met need for SRMNH services, defined as "the percentage of a universal SRMNH package that could potentially be obtained by women and newborns given the composition, competencies and available working time of the SRMNH workforce." The model defined the 46 key interventions included in this universal SRMNH package and allocated them to the available health worker time and skill set in each country to estimate the potential met need. Based on the current and projected potential met need in the future, the countries were grouped into three categories: (1) 'making or maintaining progress' (expected to meet more, or the same level, of the need in the future than currently): 14 countries including Ghana, Senegal and South Africa, (2) 'at risk' (currently performing relatively well but expected to deteriorate due to the health workforce not keeping pace with population growth): 6 countries including Gabon, Rwanda and Zambia, and (3) 'low performing' (not performing well and not expected to improve): 21 countries including Burkina Faso, Eritrea and Sierra Leone. The three groups face different challenges, and policy solutions to increasing met need should be tailored to the specific context of the country. National health workforce accounts should be strengthened so that workforce planning can be evidence-informed.

Regular rain and fogwater sampling in the Podocarpus National Park, on the humid eastern slopes of the Ecuadorian Andes, along an altitude profile between 1960 and 3180 m, has been carried out since 2002. The samples, accumulated over about 1-week intervals, were analysed for pH, conductivity and major ions (K+, Na+, NH4+, Ca2+, Mg2+, Cl-, SO42-, NO3-, PO43-). About 35% of the weekly samples had very low ion contents, with pH mostly above 5 and conductivity below 10 μS/cm. 10-days back trajectories (FLEXTRA) showed that respective air masses originated in pristine continental areas, with little or no obvious pollution sources. About 65%, however, were significantly loaded with cations and anions, with pH as low as 3.5 to 4.0 and conductivity up to 50 μS/cm. The corresponding back trajectories clearly showed that air masses had passed over areas of intense biomass burning, active volcanoes, and the ocean, with episodic Sahara and/or Namib desert dust interference. Enhanced SO42- and NO3+ were identified, by combining satellite-based fire pixel observations with back trajectories, as predominantly resulting from biomass burning. Analyses of oxygen isotopes 16O, 17O, and 18O in nitrate show that nitrate in the samples is indeed a product of atmospheric conversion of precursors. Some SO42-, about 10% of the total input, could be identified to originate from active volcanoes, whose plumes were encountered by about 10% of all trajectories. Enhanced Na+, K+, and Cl- were found to originate from ocean spray sources. They were associated with winds providing Atlantic air masses to the receptor site within less than 5 days. Episodes of enhanced Ca2+ and Mg2+ were found to be associated with air masses from African deserts. Satellite aerosol data confirm desert sources both on the Northern (Sahara) as on the Southern Hemisphere (Namib), depending on the season. A few significant PO43- peaks are related with air masses originating from North African phosphate mining fields.

Full Text Available Objective: To evaluate the influence of the temperature on honey colour, polyphenol contents and antimycotic capacity and to evaluate the correlation between these parameters. Methods: Sahara honey were heated up to 25, 50, 75 and 100 °C for 15, 30 and 60 min, and their colour intensity, polyphenol contents and antimycotic capacity. The Folin-Ciocalteu test was used to determine the total polyphenol contents (TPC. The antimycotic activity was evaluated both by agar diffusion method and micro wells dilution method against the Candida albicans (C. albicans and Candida glabrata (C. glabrata. Results: Initial values for TPC in Sahara honey ranged from 0.55 to 1.14 mg of gallic acid per kg of honey, with the average value of 0.78 mg of gallic acid per kg of honey. The TPC values after heat-treatment were 0.54 to 1.54 with the average value of 1.49 mg. The minimal inhibitory concentrations before heat-treatment of Sahara honey against C. albicans and C. glabrata ranged from 3.06%-12.5% and 50% respectively. After heat-treatment the minimal inhibitory concentrations between 12.5% and 50% for C. albicans and C. glabrata, respectively. The diameters of inhibition zones of Sahara honey with 50% concentration varied from (12.67-15.00 mm by C. albicans to (14.33-15.67 mm by C. glabrata. The diameters of inhibition zones after heat-treatment at 25 and 50 °C for 15.30 and 60 min ranged from (2.00-18.67 mm by C. albicans to (8.00-16.67 mm by C. glabrata. Statistically significant relations between the TPC and the colour intensity of Sahara honey (r=0.99, P<0.05. Furthermore, the results showed that the TPC and colour is not correlated with the antimycotic capacity. Conclusions: To our knowledge this is the first report on the antimycotic capacity of Sahara honey.

Water footprint as an indicator of agricultural productivity in African countries

2017-04-01

Sub-Saharan Africa is one of the regions with the largest scope for improved agricultural development that would contribute to global food security while respecting environmental boundaries. More importantly, undernourishment is a challenge for many African countries and needs to be addressed to achieve the 2030 Agenda for Sustainable Development. This study was conducted to support the Netherlands Ministry of Foreign Affair's Inclusive Green Growth aim of increasing water use efficiency by 25% in Dutch financed projects. A water footprint profile was developed for 7 Sub-Saharan countries; Benin, Ethiopia, Ghana, Kenya, Mali, Mozambique and Rwanda. The profiles provide an overview of water use from the perspective of the goods produced within the country, the consumption of goods, in particular agricultural crops, whether these goods are produced domestically or imported from other countries and the level of blue water scarcity experienced in the country. Across all countries, key food crops such as maize, and sorghum have low water productivity relative to the global water footprint benchmark. Export crops such as tea in Kenya or cocoa in Ghana show a good performance over global production. Furthermore, the water footprint of crops over the period 2006-2013 was compared to data from the period 1996-2005. Changes in yield and the resulting changes in the water footprint were assessed for both food and export crops. Yields in food crops improved in some countries, and in some years, but not consistently across all countries and years. The greatest gains in water productivity were in key export crops. The results provide insights into whether improvements have been made in water productivity in recent years and through comparison with the global water footprint benchmark, remaining opportunities for further gains in water productivity were identified. Going forward, policies that will enhance further improvement in water productivity and support greater food and

Sovereign bonds in developing countries: Drivers of issuance and spreads

Directory of Open Access Journals (Sweden)

Andrea F. Presbitero

2016-06-01

Full Text Available In the last decade there has been a new wave of sovereign bond issuances in Africa. What determines the ability of developing countries to issue bonds in international capital and what explains the spreads on these bonds? This paper examines these questions using a dataset that includes 105 developing countries during the period 1995–2014. We find that a country is more likely to issue a bond when, in comparison with non-issuing peers, it is larger in economic size, has higher per capita GDP, a lower public debt, and a more effective government. Spreads on sovereign bonds are lower for countries with strong external and fiscal positions, as well as robust economic growth and government effectiveness. We also find that primary spreads for the average Sub-Saharan African issuer are higher than in other regions. With regard to global factors, our results confirm the existing evidence that issuances are more likely during periods of global liquidity and high commodity prices, especially for Sub-Saharan African countries, and spreads are higher in periods of higher market volatility.

Contemporary issues on the epidemiology and antiretroviral adherence of HIV-infected adolescents in sub-Saharan Africa: a narrative review

Introduction Adolescents are a unique and sometimes neglected group in the planning of healthcare services. This is the case in many parts of sub-Saharan Africa, where more than eight out of ten of the world's HIV-infected adolescents live. Although the last decade has seen a reduction in AIDS-related mortality worldwide, largely due to improved access to effective antiretroviral therapy (ART), AIDS remains a significant contributor to adolescent mortality in sub-Saharan Africa. Although inadequate access to ART in parts of the subcontinent may be implicated, research among youth with HIV elsewhere in the world suggests that suboptimal adherence to ART may play a significant role. In this article, we summarize the epidemiology of HIV among sub-Saharan African adolescents and review their adherence to ART, emphasizing the unique challenges and factors associated with adherence behaviour. Methods We conducted a comprehensive search of online databases for articles, relevant abstracts, and conference reports from meetings held between 2010 and 2014. Our search terms included “adherence,” “compliance,” “antiretroviral use” and “antiretroviral adherence,” in combination with “adolescents,” “youth,” “HIV,” “Africa,” “interventions” and the MeSH term “Africa South of the Sahara.” Of 19,537 articles and abstracts identified, 215 met inclusion criteria, and 148 were reviewed. Discussion Adolescents comprise a substantial portion of the population in many sub-Saharan African countries. They are at particular risk of HIV and may experience worse outcomes. Although demonstrated to have unique challenges, there is a dearth of comprehensive health services for adolescents, especially for those with HIV in sub-Saharan Africa. ART adherence is poorer among older adolescents than other age groups, and psychosocial, socio-economic, individual, and treatment-related factors influence adherence behaviour among adolescents in this region.

Stretching from southern boundary of Sahara to the equator and expanding west to east from Atlantic Ocean coasts to the India Ocean coasts, the northern sub-Saharan African (NSSA) region has been subject to intense biomass burning. Comprised of savanna, shrub, tropical forest and a number of agricultural crops, the extensive fires burn belt covers central and south of NSSA during dry season (from October to March) contributes to one of the highest biomass burning rate per km2 in the world. Due to smoke particles' absorption effects of solar radiation, they can modify the surface and atmosphere temperature and thus change atmospheric stability, height of the boundary layer, regional atmospheric circulation, evaporation rate, cloud formation, and precipitation. Hence, smoke particles emitted from biomass burning over NSSA region has a significant influence to the air quality, weather and climate variability. In this study, the first version of this Fire Energetics and Emissions Research (FEER.v1) emissions of several smoke constituents including light-absorbing organic carbon (OC) and black carbon (BC) are applied to a state-of-science meteorology-chemistry model as NOAA Weather Research and Forecasting Model with Chemistry (WRF-Chem). We analyzed WRF-Chem simulations of surface and vertical distribution of various pollutants and their direct radiative effects in conjunction with satellite observation data from Moderate Resolution Imaging Spectroradiometer (MODIS) and Cloud-Aerosol Lidar data with Orthogonal Polarization (CALIPSO) to strengthen the importance of combining space measured emission products like FEER.v1 emission inventory with mesoscale model over intense biomass burning region, especially in area where ground-based air-quality and radiation-related observations are limited or absent.

Sub-Saharan African university students' beliefs about condoms, condom-use intention, and subsequent condom use: a prospective study.

Heeren, G Anita; Jemmott, John B; Mandeya, Andrew; Tyler, Joanne C

2009-04-01

Whether certain behavioral beliefs, normative beliefs, and control beliefs predict the intention to use condoms and subsequent condom use was examined among 320 undergraduates at a university in South Africa who completed confidential questionnaires on two occasions separated by 3 months. Participants' mean age was 23.4 years, 47.8% were women, 48.9% were South Africans, and 51.1% were from other sub-Saharan African countries. Multiple regression revealed that condom-use intention was predicted by hedonistic behavioral beliefs, normative beliefs regarding sexual partners and peers, and control beliefs regarding condom-use technical skill and impulse control. Logistic regression revealed that baseline condom-use intention predicted consistent condom use and condom use during most recent intercourse at 3-month follow-up. HIV/STI risk-reduction interventions for undergraduates in South Africa should target their condom-use hedonistic beliefs, normative beliefs regarding partners and peers, and control beliefs regarding technical skill and impulse control.

Sub-Saharan Africa at the global education market: role of South Africa

Directory of Open Access Journals (Sweden)

Ramil Ravilevich Asmyatullin

2016-12-01

Full Text Available This article is dedicated to the development of the higher education in Sub-Saharan countries, particularly to the topic of internationalization of education. Most African countries have underdeveloped education systems. The quality and availability of higher education is a formidable obstacle for economic and social development. There is a growing demand for higher education in the SSA, but national education systems can’t cope fully with it. Hence many students go abroad, mostly in other African countries. The article focuses on the position of South Africa in the global and regional education market. As it’s a regional leader in this field South Africa attracts more than a half of international students within the Sub-Saharan Africa. The main reasons why African students choose South Africa are geographic proximity, familiar culture, lack of wanted higher education programs in their countries. However, there are as well disadvantages like xenophobia and race discrimination. South Africa has become a leader in Africa in the field of higher education, but it plays still small part at a global scale.

A vision for a United States of Africa has been advocated since the dawn of independence by, among others, pioneers like Kwame Nkrumah, Gamal Abdel Nasser and Julius Nyerere. More recently the idea gained new momentum, through such initiatives as the New Partnership for African Development (NEPAD) and the African Union (AU) to create a single market of Africa's 750 million people that is competitive within itself and within the global economy. This would be achieved through a deliberate, systematic and concerted effort to integrate, upgrade and modernize infrastructure that would offer the required catalyst for economic growth. However, the prioritization by African policy makers of a grand plan to link up the entire African continent's electric power grid networks would appear to be incompatible with 21st century thinking. The specifications for a centrally managed power grid were made by Nicola Tesla in 1883 and have served the power industry for over 125 years but are now obsolete in the era of digital micro-electronics and smart grid concepts. This paper examines some issues that surround the evolution of sub-Sahara African regional power pools and highlights the anomalies and perhaps wrong timing around the conceptualization and prioritization of grand inter-state power grids. The authors then propose an alternative model that conforms to a new and more sustainable paradigm in electricity supply economics. The proposals are however not meant to provide a panacea but it is hoped that the article will ignite a debate that will lead to a lasting solution. (author)

The epidemiology of cardiovascular diseases in sub-Saharan Africa is unique among world regions, with about half of cardiovascular diseases (CVDs) due to causes other than atherosclerosis. CVD epidemiology data are sparse and of uneven quality in sub-Saharan Africa. Using the available data, the Global Burden of Diseases, Risk Factors, and Injuries (GBD) 2010 Study estimated CVD mortality and burden of disease in sub-Saharan Africa in 1990 and 2010. The leading CVD cause of death and disability in 2010 in sub-Saharan Africa was stroke; the largest relative increases in CVD burden between 1990 and 2010 were in atrial fibrillation and peripheral arterial disease. CVD deaths constituted only 8.8% of all deaths and 3.5% of all disability-adjusted life years (DALYs) in sub-Sahara Africa, less than a quarter of the proportion of deaths and burden attributed to CVD in high income regions. However, CVD deaths in sub-Saharan Africa occur at younger ages on average than in the rest of the world. It remains uncertain if increased urbanization and life expectancy in some parts of sub-Saharan African nations will transition the region to higher CVD burden in future years. © 2013.

Yellow fever, Asia and the East African slave trade.

Cathey, John T; Marr, John S

2014-05-01

Yellow fever is endemic in parts of sub-Saharan Africa and South America, yet its principal vectors--species of mosquito of the genus Aedes--are found throughout tropical and subtropical latitudes. Phylogenetic analyses indicate that yellow fever originated in Africa and that its spread to the New World coincided with the slave trade, but why yellow fever has never appeared in Asia remains a mystery. None of several previously proposed explanations for its absence there is considered satisfactory. We contrast the trans-Atlantic slave trade, and trade across the Sahara and to the Arabian Peninsula and Mesopotamia, with that to Far East and Southeast Asian ports before abolition of the African slave trade, and before the scientific community understood the transmission vector of yellow fever and the viral life cycle, and the need for shipboard mosquito control. We propose that these differences in slave trading had a primary role in the avoidance of yellow fever transmission into Asia in the centuries before the 20(th) century. The relatively small volume of the Black African slave trade between Africa and East and Southeast Asia has heretofore been largely ignored. Although focal epidemics may have occurred, the volume was insufficient to reach the threshold for endemicity.

Symptom research across conditions has historically focused on single symptoms, and the burden of multiple symptoms and their interactions has been relatively neglected especially in people living with HIV. Symptom cluster studies are required to set priorities in treatment planning, and to lessen the total symptom burden. This study aimed to identify and compare symptom clusters among people living with HIV attending five palliative care facilities in two sub-Saharan African countries. Data from cross-sectional self-report of seven-day symptom prevalence on the 32-item Memorial Symptom Assessment Scale-Short Form were used. A hierarchical cluster analysis was conducted using Ward's method applying squared Euclidean Distance as the similarity measure to determine the clusters. Contingency tables, X2 tests and ANOVA were used to compare the clusters by patient specific characteristics and distress scores. Among the sample (N=217) the mean age was 36.5 (SD 9.0), 73.2% were female, and 49.1% were on antiretroviral therapy (ART). The cluster analysis produced five symptom clusters identified as: 1) dermatological; 2) generalised anxiety and elimination; 3) social and image; 4) persistently present; and 5) a gastrointestinal-related symptom cluster. The patients in the first three symptom clusters reported the highest physical and psychological distress scores. Patient characteristics varied significantly across the five clusters by functional status (worst functional physical status in cluster one, ppeople living with HIV with longitudinally collected symptom data to test cluster stability and identify common symptom trajectories is recommended.

The paper attempts to test the Environment Kuznets Curve (EKC) hypothesis for 36 high-income countries for the period 1980-2005. The test is based on the suggestion of . Various panel data unit root and co-integration tests are applied. Carbon dioxide (CO{sub 2}) emissions and GDP series are integrated of order one and co-integrated, especially after controlling for cross-sectional dependence. Additionally, the Blundell-Bond system generalised methods of moments (GMM) is employed to conduct a panel causality test in a vector error-correction mechanism (VECM) setting. Unidirectional causality running from real per capita GDP to per capita CO{sub 2} emissions is uncovered in both the short-run and the long-run. The empirical analysis based on individual countries provides evidence of an EKC for Greece, Malta, Oman, Portugal and the United Kingdom. However, it can be observed that for the whole panel, a 1% increase in GDP generates an increase of 0.68% in CO{sub 2} emissions in the short-run and 0.22% in the long-run. The lower long-run income elasticity does not provide evidence of an EKC, but does indicate that, over time, CO{sub 2} emissions are stabilising in the rich countries. - Research highlights: {yields} The Environment Kuznets Curve hypothesis for 36 rich countries is studied over the period 1980-2005. {yields} approach is used and extended by including a causality analysis. {yields} Carbon dioxide (CO{sub 2}) emissions are found to be stabilizing in the rich countries.

Violence against women, especially by intimate partners, is a serious public health problem that is associated with physical, reproductive and mental health consequences. Even though most societies proscribe violence against women, the reality is that violations against women's rights are often sanctioned under the garb of cultural practices and norms, or through misinterpretation of religious tenets. We utilised data from 17 Demographic and Health Surveys (DHS) conducted between 2003 and 2007 in sub-Saharan Africa to assess the net effects of socio-demographic factors on men's and women's attitudes toward intimate partner violence against women (IPVAW) using multiple logistic regression models estimated by likelihood ratio test. IPVAW was widely accepted under certain circumstances by men and women in all the countries studied. Women were more likely to justify IPVAW than men. "Neglecting the children" was the most common reason agreed to by both women and men for justifying IPVAW followed by "going out without informing husband" and "arguing back with the husband". Increasing wealth status, education attainment, urbanization, access to media, and joint decision making were associated with decreased odds of justifying IPVAW in most countries. In most Sub-Saharan African countries studied where IPVAW is widely accepted as a response to women's transgressing gender norms, men find less justification for the practice than do women. The present study suggests that proactive efforts are needed to change these norms, such as promotion of higher education and socio-demographic development. The magnitude and direction of factors associated with attitudes towards IPVAW varies widely across the countries, thus suggesting the significance of capitalizing on need-adapted interventions tailored to fit conditions in each country.

2018-05-01

Deforestation worldwide could have important consequences for diet quality and human nutrition given the numerous ecosystem services that are provided by forests and biodiverse landscapes. Yet, empirical research assessing the links between deforestation and diets is lacking. In this study, we examined the association between deforestation and diet diversity among children using geolocated Demographic and Health Survey data for 33,777 children across 15 countries of sub-Saharan Africa coupled with remotely-sensed data on forest cover loss. Deforestation was negatively associated with diet diversity (regression coefficient (95% CI): - 0.47 (- 0.76, - 0.18)), as well as recent consumption of legumes and nuts, flesh foods, and fruits and vegetables among children aged 6 months to 24 months. Regionally, these trends were statistically significant only in the West Africa region. This hypothesis-generating research adds to the growing body of evidence that forests and forest-based ecosystems are associated with diet quality and nutrition and provides support for future studies that examine mechanisms linking forest loss and human nutrition.

Assessment of the Vulnerability of Water Resources to Seasonal Fires Across the Northern Sub-Saharan African Region

Science.gov (United States)

Ichoku, Charles M.

2010-01-01

The northern sub-Saharan African (NSSA) region, extending from the southern fringes of the Sahara to the Equator, and stretching west to east from the Atlantic to the Indian ocean coasts, plays a prominent role in the distribution of Saharan dust and other airborne matter around the region and to other parts of the world, the genesis of global atmospheric circulation, and the birth of such major (and often catastrophic) events as hurricanes. Therefore, this NSSA region represents a critical variable in the global climate change equation. Recent satellite-based studies have revealed that the NSSA region has one of the highest biomass-burning rates per unit land area among all regions of the world. Because of the high concentration and frequency of fires in this region, with the associated abundance of heat release and gaseous and particulate smoke emissions, biomass-burning activity is believed to be a major driver of the regional carbon, energy, and water cycles. We acknowledge that the rainy season in the NSSA region is from April to September while biomass burning occurs mainly during the dry season (October to March). Nevertheless, these two phenomena are indirectly coupled to each other through a chain of complex processes and conditions, including land-cover and surface-albedo changes, the carbon cycle, evapotranspiration, drought, desertification, surface water runoff, ground water recharge, and variability in atmospheric composition, heating rates, and circulation. In this presentation, we will examine the theoretical linkages between these processes, discuss the preliminary results based on satellite data analysis, and provide an overview of plans for more integrated research to be conducted over the next few years.

Split skin graft (SSG) is one of the most commonly performed operations on any Plastic Surgery service. Rate of donor site healing is affected by various factors including the type of dressing applied. The aim of this study was to survey the practice of plastic surgeons in the sub region with respect to management of SSG donor site and see how it conforms to international standards. Structured questionnaires on various aspects of the harvest and management of SSG donor sites were administered to plastic surgeons during the 53rd annual conference of the West African College of Surgeons (WACS) at Lome, Togo in March 2013. The data were analyzed using descriptive statistics. There were 47 respondents out of 55 plastic surgeons from four West African countries, which represented 85.4% of registered participants at the plastic surgery section of the conference. All the respondents performed SSG regularly, and the thigh was the most commonly used donor site. Different types of paraffin gauze remained the most commonly used primary donor site dressing. Only 17% of the respondents apply a topical local anaesthetic agent on the donor site. The choice of SSG donor site dressing in the sub region was driven mainly by availability. Concerted efforts must be made to access newer wound care products for optimum management of this commonly performed operation.

2011-03-01

Medicine benefits through health insurance programs have the potential to improve access to and promote more effective use of affordable, high quality medicines. Information is lacking about medicine benefits provided by health insurance programs in Sub-Saharan Africa. We describe the structure of medicine benefits and data routinely available for decision-making in 33 health insurance programs in Ghana, Kenya, Nigeria, Tanzania and Uganda. Most programs surveyed were private, for profit schemes covering voluntary enrollees, mostly in urban areas. Almost all provide both inpatient and outpatient medicine benefits, with members sharing the cost of medicines in all programs. Some programs use strategies that are common in high-income countries to manage the medicine benefits, such as formularies, generics policies, reimbursement limits, or price negotiation. Basic data to monitor performance in delivering medicine benefits are available in most programs, but key data elements and the resources needed to generate useful management information from the available data are typically missing. Many questions remain unanswered about the design, implementation, and effects of specific medicines policies in the emerging and expanding health insurance programs in Sub-Saharan Africa. These include questions about the most effective medicines policy choices, given different corporate and organizational structures and resources; impacts of specific benefit designs on quality and affordability of care and health outcomes; and ways to facilitate use of routine data for monitoring. Technical capacity building, strong government commitment, and international donor support will be needed to realize the benefits of medicines coverage in emerging and expanding health insurance programs in Sub-Saharan Africa.

Stigma of mental illness and substance misuse can deter help seeking, especially in immigrants who are often reluctant to seek help early for these issues. The aim of the present study was to explore the stigma experience surrounding mental illness and substance misuse, and its implications for improving help seeking, for youths and parents from sub-Saharan African immigrant communities. A qualitative, descriptive design was used. Individual interviews were undertaken with 28 youths, and focus group discussions were held with 41 parents and community leaders in Melbourne, Australia. The findings indicated that public stigma and self-stigma were common and deterred participants' help seeking within sub-Saharan African communities. There was concern about the consequences of disclosure. Personal shame, fear of community rejection, and being labelled a 'lunatic' deterred help seeking. Programmes are needed to address stigma, promote help seeking, and increase mental health knowledge. Mental health nurses and other clinicians in the mental health and alcohol and other drug fields can make an important contribution. Steps are needed to employ more sub-Saharan African immigrant clinicians to help increase help seeking from their communities. © 2017 Australian College of Mental Health Nurses Inc.

Utopia Switzerland (2) - A Country Without CO{sub 2} Emissions

Energy Technology Data Exchange (ETDEWEB)

Streit, Marco [Aare-Tessin Ltd for Electricity, Bahnhofquai 12, 4601 Olten (Switzerland)

2008-07-01

Global warming and climate change are major themes in the today's energy policy discussion. Awarding Al Gore and the IPCC with the Nobel price in 2007 shows the importance of the climate change for the whole world. That we are running into climatic problems is already known since several decades and possibilities to solve the CO{sub 2} emissions were proposed and discussed since years, but a reduction in the CO{sub 2} emissions is not detectable. This might be due to the fact, that the major part of CO{sub 2} production (traffic and heating) is not consequently touched. It seems to be easier to discuss about renewable energies in the electricity market than in other areas. And the consequences of discussing stepping out of nuclear all over the world, has enforced the problem. Although the renaissance of nuclear has started and the known positive impact to the climate from this energy source, it is not forced to be the solution for the biggest problem of the near future. There are only a few countries worldwide which produce electricity without or with only small amounts of CO{sub 2} emissions like Norway or Switzerland. Those countries could be demonstration countries to show the possibilities for reducing and avoiding CO{sub 2} emissions. Would it be possible to replace all fossil energy sources during a reasonable period of time by using nuclear energy and hydrogen as an energy storage system? Is this scenario technical feasible and of economic interest for a small, developed country like Switzerland? If yes, Switzerland might be a good candidate to establish the first CO{sub 2}-free industrial developed state in the world. Looking much more ahead this study will discuss a simple but might be effective scenario for Switzerland. The study is based on a paper presented at IYNC 2006 and will update the used data as well as going in more details. (authors)

African medical schools are expanding, straining resources at tertiary health facilities. Decentralizing clinical training can alleviate this tension. This study assessed the impact of decentralized training and contribution of undergraduate medical students at health facilities. Participants were from 11 Medical Education Partnership Initiative-funded medical schools in 10 African countries. Each school identified two clinical training sites-one rural and the other either peri-urban or urban. Qualitative and quantitative data collection tools were used to gather information about the sites, student activities, and staff perspectives between March 2015 and February 2016. Interviews with site staff were analyzed using a collaborative directed approach to content analysis, and frequencies were generated to describe site characteristics and student experiences. The clinical sites varied in level of care but were similar in scope of clinical services and types of clinical and nonclinical student activities. Staff indicated that students have a positive effect on job satisfaction and workload. Respondents reported that students improved the work environment, institutional reputation, and introduced evidence-based approaches. Students also contributed to perceived improvements in quality of care, patient experience, and community outreach. Staff highlighted the need for resources to support students. Students were seen as valuable resources for health facilities. They strengthened health care quality by supporting overburdened staff and by bringing rigor and accountability into the work environment. As medical schools expand, especially in low-resource settings, mobilizing new and existing resources for decentralized clinical training could transform health facilities into vibrant service and learning environments.

Full Text Available Abstract Objective To quantify schizophrenia trialling activity in African countries and to describe the main features of these trials. Methods We searched the Cochrane Schizophrenia Group Register, which contains 16,000 citations to 13,000 studies relating only to people with schizophrenia or schizophrenia-like illness, to identify schizophrenia trials conducted in Africa without time limitation. Results A total of 38 trials met the inclusion criteria and were included in our analysis. Of the 54 countries of Africa, only 8 produced at least one trial: South Africa produced the majority of trials (20 out of 38 trials, 53%, followed by Nigeria (7 out of 38 trials, 18% and Egypt (4 out of 38 trials, 11%. The majority of studies investigated the efficacy of pharmacological interventions, were short in duration, and employed a double-blind design. The quality of reporting was generally poor. We found six trials comparing antipsychotics from the WHO Essential List of Medicine versus new generation antipsychotics. In terms of efficacy and acceptability, these studies failed to show any advantage of newer antipsychotics over first-generation agents. Conclusions We observed an impressive mismatch between the number of individuals with schizophrenia living in African countries, estimated to be around 10 million, and the overall number of patients included in African trials, which is less than 2,000. These few trials were of low quality and appeared not to reflect the real needs of the population. We argue that the concept of pragmatism should be introduced into the design of randomized trials in African countries. Pragmatic trials should investigate whether treatments, given in real-world circumstances, really have clinically meaningful effects.

Deserts and arid regions are generally perceived as bare and rather homogeneous areas of low diversity. The Sahara is the largest warm desert in the world and together with the arid Sahel displays high topographical and climatic heterogeneity, and has experienced recent and strong climatic oscillations that have greatly shifted biodiversity distribution and community composition. The large size, remoteness and long-term political instability of the Sahara-Sahel, have limited knowledge on its biodiversity. However, over the last decade, there have been an increasing number of published scientific studies based on modern geomatic and molecular tools, and broad sampling of taxa of these regions. This review tracks trends in knowledge about biodiversity patterns, processes and threats across the Sahara-Sahel, and anticipates needs for biodiversity research and conservation. Recent studies are changing completely the perception of regional biodiversity patterns. Instead of relatively low species diversity with distribution covering most of the region, studies now suggest a high rate of endemism and larger number of species, with much narrower and fragmented ranges, frequently limited to micro-hotspots of biodiversity. Molecular-based studies are also unravelling cryptic diversity associated with mountains, which together with recent distribution atlases, allows identifying integrative biogeographic patterns in biodiversity distribution. Mapping of multivariate environmental variation (at 1 km × 1 km resolution) of the region illustrates main biogeographical features of the Sahara-Sahel and supports recently hypothesised dispersal corridors and refugia. Micro-scale water-features present mostly in mountains have been associated with local biodiversity hotspots. However, the distribution of available data on vertebrates highlights current knowledge gaps that still apply to a large proportion of the Sahara-Sahel. Current research is providing insights into key

European and Developing Countries Clinical Trials Partnership (EDCTP) was founded in 2003 by the European Parliament and Council. It is a partnership of 14 European Union (EU) member states, Norway, Switzerland, and Developing Countries, formed to fund acceleration of new clinical trial interventions to fight the human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS), malaria and tuberculosis (TB) in the sub-Saharan African region. EDCTP seeks to be synergistic with other funding bodies supporting research on these diseases. EDCTP promotes collaborative research supported by multiple funding agencies and harnesses networking expertise across different African and European countries. EDCTP is different from other similar initiatives. The organisation of EDCTP blends important aspects of partnership that includes ownership, sustainability and responds to demand-driven research. The Developing Countries Coordinating Committee (DCCC); a team of independent scientists and representatives of regional health bodies from sub-Saharan Africa provides advice to the partnership. Thus EDCTP reflects a true partnership and the active involvement and contribution of these African scientists ensures joint ownership of the EDCTP programme with European counterparts. The following have been the major achievements of the EDCTP initiative since its formation in 2003; i) increase in the number of participating African countries from two to 26 in 2008 ii) the cumulative amount of funds spent on EDCTP projects has reached 150 m euros, iii) the cumulative number of clinical trials approved has reached 40 and iv) there has been a significant increase number and diversity in capacity building activities. While we recognise that EDCTP faced enormous challenges in its first few years of existence, the strong involvement of African scientists and its new initiatives such as unconditional funding to regional networks of excellence in sub-Saharan Africa is envisaged to

Methods We utilised data from 17 Demographic and Health Surveys (DHS conducted between 2003 and 2007 in sub-Saharan Africa to assess the net effects of socio-demographic factors on men's and women's attitudes toward intimate partner violence against women (IPVAW using multiple logistic regression models estimated by likelihood ratio test. Results IPVAW was widely accepted under certain circumstances by men and women in all the countries studied. Women were more likely to justify IPVAW than men. "Neglecting the children" was the most common reason agreed to by both women and men for justifying IPVAW followed by "going out without informing husband" and "arguing back with the husband". Increasing wealth status, education attainment, urbanization, access to media, and joint decision making were associated with decreased odds of justifying IPVAW in most countries. Conclusion In most Sub-Saharan African countries studied where IPVAW is widely accepted as a response to women's transgressing gender norms, men find less justification for the practice than do women. The present study suggests that proactive efforts are needed to change these norms, such as promotion of higher education and socio-demographic development. The magnitude and direction of factors associated with attitudes towards IPVAW varies widely across the countries, thus suggesting the significance of capitalizing on need-adapted interventions tailored to fit conditions in each country.

Data on social representations of world history have been collected everywhere in the world except sub-Saharan Africa. Two studies using open-ended data involving university students from six African countries fill this gap. In Study 1, nominations from Cape Verde and Mozambique for the most important events in world history in the past 1000 years were dominated by war and politics, recency effects, and Western-centrism tempered by African sociocentrism on colonization and independence. The first three findings replicated previous research conducted in other parts of the world, but the last pattern contrasted sharply with European data. Study 2 employed a novel method asking participants how they would begin the narration of world history, and then to describe a major transition to the present. Participants most frequently wrote about the evolution of humanity out of Africa, followed by war and then colonization as a beginning, and then replicated previous findings with war, colonization, and technology as major transitions to the present. Finally, when asked about how they foresaw the future, many participants expressed hope for peace and cooperation, especially those facing more risk of collective violence (Burundi and Congo). A colonial/liberation narrative was more predominant in the data from former Portuguese colonies (Angola, Cape Verde, and Guinea-Bissau) than from former Belgian colonies (Burundi and Congo).

The New Oil-Related Issues in the Sahara

Auge, Benjamin

2011-01-01

The Sahara is one of the last African regions to remain under-explored by oil companies. After the swift rise in crude oil prices about a decade ago, the land-locked nature of the terrain, the main hurdle standing in the way of exploration, had been overcome thanks to an exponential growth in sums set aside for exploration. The arrival on the scene of State enterprises, especially from China, also made profitability secondary to the pressing need to find new reserves. A study of the state of affairs in Mauritania, Mali, Niger, and Chad discloses how the situation differs from case to case. Some are already producing like Mauritania, albeit in small quantities, and Chad, which is the sole net exporter of the region, whereas Niger will begin producing in 2012 and Mali has not had a single well drilled for decades due to its haphazard choice of oil companies. The four States mentioned do not cooperate in any way in the oil sector even though this ought to be essential in a zone that has such special peculiarities in terms of climate, geography, and security as it is facing the threat of Al Qaeda in the Islamic Maghreb (AQMI) and the Tuareg

Refraining from terror: the puzzle of non violence in Western Sahara

Full Text Available In Western Sahara, the former Spanish colony occupied by Morocco since 1975, virtually no violent resistance has been mounted by the indigenous Sahrawi people since the end of the 1975-1991 war between Morocco and the pro-independence Polisario Front. This absence of violence is puzzling in the light of several factors: the widespread public support for independence; the social and economic disparities between Moroccan and Sahrawi inhabitants of the territory; and Morocco’s brutal repression of Sahrawi culture, resistance, and expressions of proindependence feeling. This article examines the logic of violence (and its absence and of resistance, and draws lessons from Western Sahara. As well as advancing theoretical development, the article makes a methodological contribution to the study of resistance, and improves our understanding of the Western Sahara conflict through fieldwork, including around 60 interviews with Sahrawi activists conducted in the summer of 2014.

Reflections on entrepreneurship education in African tertiary institutions

2006-12-01

Full Text Available It is a well-established fact that several developed economies grew on the back of small businesses and entrepreneurial development. It stands to reason then that the development of Sub-Saharan Africa (SSA can also be catalysed by a rise in the number of entrepreneurs and entrepreneurial activity. In that general regard, this paper sought to investigate the state of entrepreneurship education in Sub-Saharan Africa (SSA. The method adopted in investigating this phenomenon was to critique the existing tertiary education entrepreneurship structures (where these existed at all and to proffer recommendations where anomalies were discovered. It came to light that despite the critical importance of entrepreneurs in the economic development of a nation, Sub-Saharan African (SSA countries have not fully developed strategies to tap this resource. What the countries have, are haphazard policies designed to promote the lesser or uneducated individuals in the informal sector into entrepreneurship. SSA educational leaders must find ways to structure their curricula so that all or most of their students can take courses in entrepreneurship. This is essential for SSA countries in order to move them from their present disadvantaged economic status, to greater economic and social development. A tentative syllabus for African tertiary education is proffered at the end of the article but its robustness needs to be tested.

Prata, Ndola; Weidert, Karen; Sreenivas, Amita

2013-07-01

The need for a concerted effort to address the gaps in family planning services for youth in sub-Saharan Africa has been underreported and underexplored. Trends in fertility, childbearing, unmet need for family planning options and contraceptive prevalence (CP) among youth are described with data from six African countries with four consecutive Demographic and Health Surveys. Estimates of exposure to risk of pregnancy and number of new contraceptives users needed to maintain and double CP in 2015 are calculated using current CP and projected youth population size in six African countries. The youth population is expected to range from approximately 3 to 35 million in six African countries by 2015. Accounting for population growth and current estimates of sexual activity among youth, family planning services will need to absorb more than 800,000 and 11.3 million new contraceptive users total to maintain and double CP, respectively, in 2015 in those six African countries alone. Our findings support existing literature that calls for a reorientation of family planning policies and programs, especially improved access to modern contraceptive methods among African youth.

Lakeside cemeteries in the Sahara: 5000 years of holocene population and environmental change.

Directory of Open Access Journals (Sweden)

Paul C Sereno

Full Text Available BACKGROUND: Approximately two hundred human burials were discovered on the edge of a paleolake in Niger that provide a uniquely preserved record of human occupation in the Sahara during the Holocene ( approximately 8000 B.C.E. to the present. Called Gobero, this suite of closely spaced sites chronicles the rapid pace of biosocial change in the southern Sahara in response to severe climatic fluctuation. METHODOLOGY/PRINCIPAL FINDINGS: Two main occupational phases are identified that correspond with humid intervals in the early and mid-Holocene, based on 78 direct AMS radiocarbon dates on human remains, fauna and artifacts, as well as 9 OSL dates on paleodune sand. The older occupants have craniofacial dimensions that demonstrate similarities with mid-Holocene occupants of the southern Sahara and Late Pleistocene to early Holocene inhabitants of the Maghreb. Their hyperflexed burials compose the earliest cemetery in the Sahara dating to approximately 7500 B.C.E. These early occupants abandon the area under arid conditions and, when humid conditions return approximately 4600 B.C.E., are replaced by a more gracile people with elaborated grave goods including animal bone and ivory ornaments. CONCLUSIONS/SIGNIFICANCE: The principal significance of Gobero lies in its extraordinary human, faunal, and archaeological record, from which we conclude the following: The early Holocene occupants at Gobero (7700-6200 B.C.E. were largely sedentary hunter-fisher-gatherers with lakeside funerary sites that include the earliest recorded cemetery in the Sahara.Principal components analysis of craniometric variables closely allies the early Holocene occupants at Gobero with a skeletally robust, trans-Saharan assemblage of Late Pleistocene to mid-Holocene human populations from the Maghreb and southern Sahara.Gobero was abandoned during a period of severe aridification possibly as long as one millennium (6200-5200 B.C.E.More gracile humans arrived in the mid

Little is known about the influence of control beliefs on antiretroviral drug adherence in patients who migrated from sub-Saharan Africa to Europe. The aim of this study was to explore the differences in health locus of control and control beliefs between HIV infected patients from sub-Saharan Africa with and without a lifetime experience of migration. A sample of 62 HIV infected consecutive patients referred to the HIV clinics at the University Hospital of Münster (Germany) and at the Rubaga Hospital Kampala (Uganda) were enrolled into this study. We compared three groups of patients: sub-Saharan African migrants, German patients, and local Ugandan patients. We used the German health and illness related control beliefs questionnaire (KKG), the Competence and control beliefs questionnaire (FKK), and the Powe Fatalism Inventory-HIV/AIDS-Version (PFI-HIV/AIDS-Version) and translated these scales into English and Luganda. In addition, the patients' sociodemographic, acculturation, clinical, and immunological data were registered. Significant results were shown in HIV related external locus of control between migrated sub-Saharan African and local Ugandan patients compared to German patients. General control beliefs showed no significant differences. In the PFI-HIV-Version, there was a significant difference between migrated sub-Saharan African and Ugandan patients compared to German patients. Our data suggest that the experience of migration does not influence the locus of control. Compared to German HIV patients, African patients in general showed a significantly higher external health locus of control which might have implications for drug adherence.

The private sector role in HIV/AIDS in the context of an expanded global response: expenditure trends in five sub-Saharan African countries.

Sulzbach, Sara; De, Susna; Wang, Wenjuan

2011-07-01

Global financing for the HIV response has reached unprecedented levels in recent years. Over US$10 billion were mobilized in 2007, an effort credited with saving the lives of millions of people living with HIV (PLHIV). A relatively unexamined aspect of the global HIV response is the role of the private sector in financing HIV/AIDS services. As the nature of the response evolves from emergency relief to long-term sustainability, understanding current and potential contributions from the private sector is critical. This paper examines trends in private sector financing, management and resource consumption related to HIV/AIDS in five sub-Saharan African countries, with a particular emphasis on the effects of recently scaled-up donor funding on private sector contributions. We analysed National Health Accounts HIV/AIDS subaccount data for Kenya, Malawi, Rwanda, Tanzania and Zambia between 2002 and 2006. HIV subaccounts provide comparable data on the flow of HIV/AIDS funding from source to use. Findings indicate that private sector contributions decreased in all countries except Tanzania. With regards to managing HIV/AIDS funds, non-governmental organizations are increasingly controlling the largest share of resources relative to other stakeholders, whereas private for-profit entities are managing fewer HIV/AIDS resources since the donor influx. The majority of HIV/AIDS funds were spent in the public sector, although a considerable amount was spent at private facilities, largely fuelled by out-of-pocket (OOP) payments. On the whole, OOP spending by PLHIV decreased over the 4-year period, with the exception of Malawi, demonstrating that PLHIV have increased access to free or subsidized HIV/AIDS services. Our findings suggest that the influx of donor funding has led to decreased private contributions for HIV/AIDS. The reduction in private sector investment and engagement raises concerns about the sustainability of HIV/AIDS programmes over the long term, particularly in

Rapid screening of toxic glycoalkaloids and micronutrients in edible nightshades (Solanum spp.

Full Text Available African indigenous vegetables (AIVs because of their nutrient density have the unique potential to reduce micronutrient deficiencies in sub-Saharan Africa, yet some may also contain anti-nutritive compounds. Vegetable nightshades from Solanum americanum, Solanum nigrum, Solanum scabrum and Solanum villosum are among the major AIVs used as a leafy vegetables and consumed regularly in many countries in sub-Sahara Africa. These under-recognized food crops have not been subjected to extensive studies for their nutritional and antinutritive factors. In this study, 15 entries of the vegetable nightshades were field-grown and the leaves which are the consumed product of commerce chemically profiled by LC/ESI-MS. Twenty-three flavones, eight saponins, and two glycoalkaloids along with a phenolic acid of chlorogenic acid were identified by MS and UV data. Anti-nutrient glycoalkaloids were quantified as total aglycones after acidic hydrolysis using MS detection and found to be within safe-consumption thresholds by comparison with the glycoalkaloid level in the globally consumed Solanum member eggplants. Edible nightshades were also found to be sources of β-carotene, vitamin E and total polyphenols and exhibited high antioxidant activity. Results of this study support that consumption of vegetable nightshades are safe from the presence of glycoalkaloids and thus, can contribute to the reduction of micronutrient deficiency in sub-Sahara Africa. Keywords: Alkaloids, Flavonoids, Carotene, Vitamin E, Antioxidant activity, Saponins, Solanum

The negative consequences of the brain drain of sub-Saharan African health workers for source countries are well documented and include understaffed facilities, decreased standards of care and higher workloads. However, studies suggest that, if migrated health workers eventually return to their home countries, this may lead to beneficial effects following the transfer of their acquired skills and knowledge (brain gain). The present study aims to explore the factors influencing the intentions for return migration of sub-Saharan African health workers who emigrated to Austria and Belgium, and gain further insight into the potential of circular migration. Semi-structured interviews with 27 sub-Saharan African health workers in Belgium and Austria were conducted. As mentioned by the respondents, the main barriers for returning were family, structural crises in the source country, and insecurity. These barriers overrule the perceived drivers, which were nearly all pull factors and emotion driven. Despite the fact that only a minority plans to return permanently, many wish to return regularly to work in the healthcare sector or to contribute to the development of their source country. As long as safety and structural stability cannot be guaranteed in source countries, the number of return migrants is likely to remain low. National governments and regional organizations could play a role in facilitating the engagement of migrant health workers in the development of the healthcare system in source countries.

Purchasing power parity is used as a basis for international income and expenditure comparison through the exchange rate theory. However, empirical studies show disagreement on the validity of PPP. In this paper, we conduct the testing on the validity of PPP using panel data approach. We apply seven different panel unit root tests to test the validity of the purchasing power parity (PPP) hypothesis based on the quarterly data on real effective exchange rate for 21 African countries from the period 1971: Q1-2012: Q4. All the results of the seven tests rejected the hypothesis of stationarity meaning that absolute PPP does not hold in those African Countries. This result confirmed the claim from previous studies that standard panel unit tests fail to support the PPP hypothesis.

Many young migrants and their parents are reluctant to seek help for mental health and substance use problems. Help-seeking delays can result in longer duration of untreated problems and poorer outcomes. In this study, we aimed to identify the help-seeking barriers and facilitators for anxiety, depression and alcohol and drug use problems in young people from recently established sub-Saharan African migrant communities. A qualitative study, incorporating individual, in-depth interviews and focus group discussions, was undertaken in Melbourne, Australia. Twenty-eight young sub-Saharan African migrants participated in the individual interviews, and 41 sub-Saharan African-born parents and key community leaders participated in 4 focus groups. All participants were aged 16 years or over. A thematic analysis of the data was undertaken. Themes and related sub-themes were abstracted from the data, reflecting the young people's, parents' and key community leaders' beliefs about barriers and facilitators to help-seeking for mental health and substance use problems. Four help-seeking barriers were identified: stigma of mental illness, lack of mental health literacy in parents and young people, lack of cultural competency of formal help sources, and financial costs deterring access. Five help-seeking facilitators were abstracted: being open with friends and family, strong community support systems, trustworthiness and confidentiality of help-sources, perceived expertise of formal help-sources, increasing young people's and parents' mental health literacy. Programs that identify and build on help-seeking facilitators while addressing help-seeking barriers are needed to address mental health issues among young sub-Saharan African migrants. Strategies to address help-seeking barriers should consider counteracting stigma and increasing mental health literacy in sub-Saharan African communities, increasing health providers' cultural competency and perceived trustworthiness, and

IAEA to Help West African Countries Diagnose Ebola

International Nuclear Information System (INIS)

2014-01-01

Full text: The International Atomic Energy Agency (IAEA) will provide specialized diagnostic equipment to help Sierra Leone in its efforts to combat an ongoing Ebola Virus Disease (EVD) outbreak, IAEA Director General Yukiya Amano announced today. Later, the support is planned to be extended to Liberia and Guinea. The support is in line with a UN Security Council appeal and responds to a request from Sierra Leone. The IAEA assistance will supplement the country's ability to diagnose EVD quickly using a diagnostic technology known as Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The assistance, expected to be delivered in the coming weeks, initiates broader IAEA support to African Member States to strengthen their technological abilities to detect diseases transmitted from animals to humans - zoonotic diseases. The IAEA and the Food and Agriculture Organization of the United Nations have been at the forefront of developing RT-PCR, a nuclear-derived technology which allows EVD to be detected within a few hours, while other methods require growing on a cell culture for several days before a diagnosis is determined. Early diagnosis of EVD, if combined with appropriate medical care, increases the victims' chance of survival and helps curtail the spread of the disease by making it possible to isolate and treat the patients earlier. Health authorities in Sierra Leone and other affected countries are already applying RT-PCR, but their diagnostic capability is limited; there is a shortage of the diagnostic kits and other materials needed for the process and backup equipment is needed to avoid diagnostic downtime in case of equipment failure. The IAEA will support the most affected countries' sustained ability to detect the disease in cooperation with the World Health Organization (WHO) and the United Nations Mission for Ebola Emergency Response. The IAEA, as part of its ongoing work, has helped 32 African countries and several other Member States develop skills

Using Cluster Analysis to Group Countries for Cost-effectiveness Analysis: An Application to Sub-Saharan Africa.

Russell, Louise B; Bhanot, Gyan; Kim, Sun-Young; Sinha, Anushua

2018-02-01

To explore the use of cluster analysis to define groups of similar countries for the purpose of evaluating the cost-effectiveness of a public health intervention-maternal immunization-within the constraints of a project budget originally meant for an overall regional analysis. We used the most common cluster analysis algorithm, K-means, and the most common measure of distance, Euclidean distance, to group 37 low-income, sub-Saharan African countries on the basis of 24 measures of economic development, general health resources, and past success in public health programs. The groups were tested for robustness and reviewed by regional disease experts. We explored 2-, 3- and 4-group clustering. Public health performance was consistently important in determining the groups. For the 2-group clustering, for example, infant mortality in Group 1 was 81 per 1,000 live births compared with 51 per 1,000 in Group 2, and 67% of children in Group 1 received DPT immunization compared with 87% in Group 2. The experts preferred four groups to fewer, on the ground that national decision makers would more readily recognize their country among four groups. Clusters defined by K-means clustering made sense to subject experts and allowed a more detailed evaluation of the cost-effectiveness of maternal immunization within the constraint of the project budget. The method may be useful for other evaluations that, without having the resources to conduct separate analyses for each unit, seek to inform decision makers in numerous countries or subdivisions within countries, such as states or counties.

2006-07-01

To investigate associations between mortalities in African countries and problems that emerged in Africa in the 1990s (reduction of national income, HIV/AIDS and political instability) by adjusting for the influences of development, sanitation and education. We compiled country-level indicators of mortalities, national net income (the reduction of national income by the debt), infection rate of HIV/AIDS, political instability, demography, education, sanitation and infrastructure, from 1990 to 2000 of all African countries (n=53). To extract major factors from indicators of the latter four categories, we carried out principal component analysis. We used multiple regression analysis to examine the associations between mortality indicators and national net income per capita, infection rate of HIV/AIDS, and political instability by adjusting the influence of other possible mortality determinants. Mean of infant mortality per 1000 live births (IMR); maternal mortality per 100,000 live birth (MMR); adult female mortality per 1000 population (AMRF); adult male mortality per 1000 population (AMRM); and life expectancy at birth (LE) in 2000 were 83, 733, 381, 435, and 51, respectively. Three factors were identified as major influences on development: education, sanitation and infrastructure. National net income per capita showed independent negative associations with MMR and AMRF, and a positive association with LE. Infection rate of HIV/AIDS was independently positively associated with AMRM and AMRF, and negatively associated with LE in 2000. Political instability score was independently positively associated with MMR. National net income per capita, HIV/AIDS and political status were predictors of mortality indicators in African countries. This study provided evidence for supporting health policies that take economic and political stability into account.

Background The aim of the study was to analyse trends in the relationship between mother’s educational level and mortality of children under the year of five in Sub-Saharan Africa, from 1990 to 2015. Data and Methods Data used in this study came from different waves of Demographic and Health Surveys (DHS) of Sub-Saharan countries. Logistic regression and Buis’s decomposition method were used to explore the effect of mother’s educational level on the mortality of children under five years. Results Although the results of our study in the selected countries show that under-five mortality rates of children born to mothers without formal education are higher than the mortality rates of children of educated mothers, it appears that differences in mortality were reduced over the past two decades. In selected countries for our study, we noticed a significant decline in mortality among children of non-educated mothers compared to the decrease in mortality rates among children of educated mothers during the period of 1990–2010. The results show that the decline in mortality of children under five years was much higher among the children born to mothers who have never received formal education—112 points drop in Malawi, over 80 in Zambia and Zimbabwe, 65 points in Burkina Faso, 56 in Congo, 43 in Namibia, 27 in Guinea, Cameroon, and 22 to 15 in Niger. However, we noted a variation in results among the countries selected for the study—in Burkina Faso (OR = 0.7), in Cameroon (OR = 0.8), in Guinea (OR = 0.8) and Niger (OR = 0.8). It is normally observed that children of mothers with 0–6 years of education are about 20% more likely to survive until their fifth year compared to children of mothers who have not been to school. Conversely, the results did not reveal significant differences between the under-five deaths of children born to non-educated mothers and children of low-level educated mothers in Congo, Malawi and Namibia. Conclusion The decline in under

This study explored the demographic and social factors, including perceived HIV stigma, that influence job satisfaction in nurses from 5 African countries. A cross-sectional survey was conducted of nurses (n = 1,384) caring for patients living with HIV infection in Lesotho, Malawi, South Africa, Swaziland, and Tanzania. Total job satisfaction in this sample was lower than 2 comparable studies in South Africa and the United Kingdom. The Personal Satisfaction subscale was the highest in this sample, as in the other 2. Job satisfaction scores differed significantly among the 5 countries, and these differences were consistent across all subscales. A hierarchical regression showed that mental and physical health, marital status, education level, urban/rural setting, and perceived HIV stigma had significant influence on job satisfaction. Perceived HIV stigma was the strongest predictor of job dissatisfaction. These results provide new areas for intervention strategies that might enhance the work environment for nurses in these countries.

2016-06-01

Full Text Available In the framework of the Fennec international programme, a field campaign was conducted in June 2011 over the western Sahara. It led to the first observational data set ever obtained that documents the dynamics, thermodynamics and composition of the Saharan atmospheric boundary layer (SABL under the influence of the heat low. In support to the aircraft operation, four dust forecasts were run daily at low and high resolutions with convection-parameterizing and convection-permitting models, respectively. The unique airborne and ground-based data sets allowed the first ever intercomparison of dust forecasts over the western Sahara. At monthly scale, large aerosol optical depths (AODs were forecast over the Sahara, a feature observed by satellite retrievals but with different magnitudes. The AOD intensity was correctly predicted by the high-resolution models, while it was underestimated by the low-resolution models. This was partly because of the generation of strong near-surface wind associated with thunderstorm-related density currents that could only be reproduced by models representing convection explicitly. Such models yield emissions mainly in the afternoon that dominate the total emission over the western fringes of the Adrar des Iforas and the Aïr Mountains in the high-resolution forecasts. Over the western Sahara, where the harmattan contributes up to 80 % of dust emission, all the models were successful in forecasting the deep well-mixed SABL. Some of them, however, missed the large near-surface dust concentration generated by density currents and low-level winds. This feature, observed repeatedly by the airborne lidar, was partly forecast by one high-resolution model only.

Full Text Available Background There is paucity of data-driven scientific reports from sub-Saharan Africa on the burden of spontaneous intracerebral haemorrhage (sICH. We have maintained a prospective consecutive in-hospital data base of cases of sICH referred for neurosurgical intervention over a 5-year period. Methods This is a cross-sectional descriptive study of the clinical epidemiology and brain-CT characterization of sICH from the data base in this region in the current era. Results There were 63 subjects, 38 (60.3% males, aged 28 to 85 years, mean 55.7 (SD, 12.7, the modal age distribution being the sixth decade. Uncontrolled hypertension was the main predisposition in the study: present, premorbid, in 79% but uncontrolled in 88% of these known cases, and exhibited malignant derangements of blood pressure in more than half. The clinical ictus to in-hospital presentation was delayed, median 72 hours; was in severe clinical state in 70%; 57% was comatose, and was complicated with fever in 57% and respiratory morbidity also in 55.6%. The main clinical symptomatology was hemiparesis, headache, vomiting and aphasia. The sICH was supratentorial on brain CT in 85.7%, ganglionic in 50.8% and thalamic in 58.3% of the latter. The bleed had CT evidence of mass effect and intraventricular extension in more than half. Twenty three patients (36.5% underwent operative interventionsConclusions In this patient population, sICH is mainly ganglionic and thalamic in location with significant rate of associated IVH. In-hospital clinical presentation is delayed and in critical state, and, the bleeding is uncontrolled hypertension related in >95%.

Sahara Coal: the fine art of collecting fines for profit

Energy Technology Data Exchange (ETDEWEB)

Schreckengost, D.; Arnold, D.

1984-09-01

Because of a change in underground mining methods that caused a considerable increase in the amount of fine sizes in the raw coal, Sahara Coal Co. designed and constructed a unique and simple fine coal system at their Harrisburg, IL prep plant. Before the new system was built, the overload of the fine coal circuit created a cost crunch due to loss of salable coal to slurry ponds, slurry pond cleaning costs, and operating and maintenance costs--each and every one excessive. Motivated by these problems, Sahara designed a prototype system to dewater the minus 28 mesh refuse. The success of the idea permitted fine refuse to be loaded onto the coarse refuse belt. Sahara also realized a large reduction in pond cleaning costs. After a period of testing, an expanded version of the refuse system was installed to dewater and dry the 28 mesh X 0 clean coal. Clean coal output increased about 30 tph. Cost savings justified the expenditures for the refuse and clean coal systems. These benefits, combined with increased coal sales revenue, paid back the project costs in less than a year.

Prevention of mother-to-child transmission (PMTCT) of HIV is a life-saving public health intervention. Sub-Saharan African (SSA) countries have made significant progress in the programme, but little is known about the strategies used by them to eliminate mother-to-child transmission of HIV. To map evidence of strategies and interventions employed by SSA in bridging the implementation gap in the rapidly changing PMTCT of HIV programme policy. Electronic search of the databases MEDLINE, PubMed and SABINET for articles published in English between 2001 and August 2016. Key words included 'Sub-Saharan African countries', 'implementation strategies', 'interventions to bridge implementation gap', 'prevention of mother-to-child transmission of HIV' and 'closing implementation gap'. Of a total of 743 articles, 25 articles that met the inclusion criteria were included in the study. Manual content analysis resulted in the identification of three categories of strategies: (1) health system (referral systems, integration of services, supportive leadership, systematic quality-improvement approaches that vigorously monitors programme performance); (2) health service delivery (task shifting, networking, shared platform for learning, local capacity building, supportive supervision); as well as (3) community-level strategies (community health workers, technology use - mHealth, family-centred approaches, male involvement, culturally appropriate interventions). There are strategies that exist in SSA countries. Future research should examine multifaceted scientific models to prioritise the highest impact and be evaluated for effectiveness and efficiency.

Increasing access to skilled birth attendance, usually via childbirth in health facilities, is a key intervention to reduce maternal and perinatal mortality and morbidity. Yet, in some countries of sub-Saharan Africa, the uptake is Health Surveys from 34 sub-Saharan African countries were used to assess women's delivery locations. 72 772 women having their first birth in the 5 years preceding the surveys were included in the analysis. Proportions and 95% CIs of facility-based deliveries were estimated overall and by country. Multivariable logistic regression was used to calculate the odds of facility-based delivery for different maternal age groups (15-19, 20-24 and ≥25 years) for a pooled sample of all countries. 59.9% of women had a facility-based delivery for their first birth (95% CI 58.6 to 61.2), ranging from 19.4% in Chad to 96.6% in Rwanda. Compared with women aged 15-19 years, the adjusted odds of having a facility-based delivery for those aged 20-24 was 1.4 (95% CI 1.3 to 1.5, psub-Saharan Africa. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Nygaard, Ivan; Hansen, Ulrich Elmer; Mackenzie, Gordon; Pedersen, Mathilde Brix

2017-08-01

This paper investigates how African governments are considering supporting and promoting the diffusion of solar PV. This issue is explored by examining so-called 'technology action plans (TAPs)', which were main outputs of the Technology Needs Assessment project implemented in 10 African countries from 2010 to 2013. The paper provides a review of three distinct but characteristic trajectories for PV market development in Kenya (private-led market for solar home systems), Morocco (utility-led fee-for service model) and Rwanda (donor-led market for institutional systems). The paper finds that governments' strategies to promoting solar PV are moving from isolated projects towards frameworks for market development and that there are high expectations to upgrading in the PV value chain through local assembly of panels and local production of other system elements. Commonly identified measures include support to: local production; financing schemes; tax exemptions; establishment and reinforcement of standards; technical training; and research and development.

The paper evaluates effects of energy resource development within the Greater Mekong Sub-region (GMS) on energy supply mix, energy system cost, energy security and environment during 2000-2035. A MARKAL-based integrated energy system model of the five GMS countries was developed to examine benefits of regional energy resource development for meeting the energy demand of these countries. The study found that an unrestricted energy resource development and trade within the region would reduce the total-regional energy systems cost by 18% and would abate the total CO{sub 2} emission by 5% as compared to the base case. All the five countries except Myanmar would benefit from the expansion of regional energy resource integration in terms of lower energy systems costs and better environmental qualities. An imposition of CO{sub 2} emission reduction constraint by 5% on each of the study countries from that of the corresponding emissions under the unrestricted energy resource development in the GMS is found to improve energy security, reduce energy import and fossil fuels dependences and increase volume of power trade within the region. The total energy system cost under the joint CO{sub 2} emission reduction strategy would be less costly than that under the individual emission targets set for each country. (author)

Laboratory capacity building for the International Health Regulations (IHR[2005]) in resource-poor countries: the experience of the African Field Epidemiology Network (AFENET).

Laboratory is one of the core capacities that countries must develop for the implementation of the International Health Regulations (IHR[2005]) since laboratory services play a major role in all the key processes of detection, assessment, response, notification, and monitoring of events. While developed countries easily adapt their well-organized routine laboratory services, resource-limited countries need considerable capacity building as many gaps still exist. In this paper, we discuss some of the efforts made by the African Field Epidemiology Network (AFENET) in supporting laboratory capacity development in the Africa region. The efforts range from promoting graduate level training programs to building advanced technical, managerial and leadership skills to in-service short course training for peripheral laboratory staff. A number of specific projects focus on external quality assurance, basic laboratory information systems, strengthening laboratory management towards accreditation, equipment calibration, harmonization of training materials, networking and provision of pre-packaged laboratory kits to support outbreak investigation. Available evidence indicates a positive effect of these efforts on laboratory capacity in the region. However, many opportunities exist, especially to support the roll-out of these projects as well as attending to some additional critical areas such as biosafety and biosecuity. We conclude that AFENET's approach of strengthening national and sub-national systems provide a model that could be adopted in resource-limited settings such as sub-Saharan Africa.

Sub-Saharan Africa: Sustainability Risk Discussion

Victoria Bakhtina

2011-11-01

Full Text Available Africa is a rising star - one of the most desirable investment destinations in the world. Nonetheless, economic growth is uneven among African countries, and many obstacles must be overcome in order to realize the full potential of opportunity. To achieve long-term sustainable investment results, and ultimately progress towards Sustainable Development goals, many risks must be isolated, analyzed, and mitigated. This paper introduces the concept of Sustainability Risk, identifying a set of major risk components for Sub-Saharan Africa and building an integral measure to quantify the degree of remoteness of the forty-six Sub-Saharan Africa countries from the total set of threats considered. The countries are separated into distinct groups with similar characteristics in terms of Sustainability Risk, and an analysis for potential decision-making, based on the visualization of the countries' position in relation to the major sustainability threats, is performed for each group. The research identifies risks with maximum impacts.

The aim of this study was to assess and characterize Mycobacterium tuberculosis complex (MTBC) genotypic diversity in Tanzania, as well as in neighbouring East and other several African countries. We used spoligotyping to identify a total of 293 M. tuberculosis clinical isolates (one isolate per patient) collected in the Bunda, Dar es Salaam, Ngorongoro and Serengeti areas in Tanzania. The results were compared with results in the SITVIT2 international database of the Pasteur Institute of Guadeloupe. Genotyping and phylogeographical analyses highlighted the predominance of the CAS, T, EAI, and LAM MTBC lineages in Tanzania. The three most frequent Spoligotype International Types (SITs) were: SIT21/CAS1-Kili (n = 76; 25.94%), SIT59/LAM11-ZWE (n = 22; 7.51%), and SIT126/EAI5 tentatively reclassified as EAI3-TZA (n = 18; 6.14%). Furthermore, three SITs were newly created in this study (SIT4056/EAI5 n = 2, SIT4057/T1 n = 1, and SIT4058/EAI5 n = 1). We noted that the East-African-Indian (EAI) lineage was more predominant in Bunda, the Manu lineage was more common among strains isolated in Ngorongoro, and the Central-Asian (CAS) lineage was more predominant in Dar es Salaam (p-value<0.0001). No statistically significant differences were noted when comparing HIV status of patients vs. major lineages (p-value = 0.103). However, when grouping lineages as Principal Genetic Groups (PGG), we noticed that PGG2/3 group (Haarlem, LAM, S, T, and X) was more associated with HIV-positive patients as compared to PGG1 group (Beijing, CAS, EAI, and Manu) (p-value = 0.03). This study provided mapping of MTBC genetic diversity in Tanzania (containing information on isolates from different cities) and neighbouring East African and other several African countries highlighting differences as regards to MTBC genotypic distribution between Tanzania and other African countries. This work also allowed underlining of spoligotyping patterns tentatively grouped within the newly designated EAI3-TZA

African Female Physicians and Nurses in the Global Care Chain: Qualitative Explorations from Five Destination Countries.

Directory of Open Access Journals (Sweden)

Silvia Wojczewski

Full Text Available Migration of health professionals is an important policy issue for both source and destination countries around the world. The majority of migrant care workers in industrialized countries today are women. However, the dimension of mobility of highly skilled females from countries of the global south has been almost entirely neglected for many years. This paper explores the experiences of high-skilled female African migrant health-workers (MHW utilising the framework of Global Care Chain (GCC research. In the frame of the EU-project HURAPRIM (Human Resources for Primary Health Care in Africa, the research team conducted 88 semi-structured interviews with female and male African MHWs in five countries (Botswana, South Africa, Belgium, Austria, UK from July 2011 until April 2012. For this paper we analysed the 34 interviews with female physicians and nurses using the qualitative framework analysis approach and the software atlas.ti. In terms of the effect of the migration on their career, almost all of the respondents experienced short-term, long-term or permanent inability to work as health-care professionals; few however also reported a positive career development post-migration. Discrimination based on a foreign nationality, race or gender was reported by many of our respondents, physicians and nurses alike, whether they worked in an African or a European country. Our study shows that in addition to the phenomenon of deskilling often reported in GCC research, many female MHW are unable to work according to their qualifications due to the fact that their diplomas are not recognized in the country of destination. Policy strategies are needed regarding integration of migrants in the labour market and working against discrimination based on race and gender.

Here, the Panel seemingly unrelated regressions augmented Dickey-Fuller test (SURADF) test, first introduced and advanced by Breuer et al. [Misleading inferences from panel unit-root tests with an illustration from purchasing power parity, Rev. Int. Econ. 9(3) (2001) 482-493], is used to investigate the mean-reverting behavior of the current account of 48 African countries during the 1980-2004 periods. The empirical results from numerous panel-based unit root tests, conducted earlier, indicated that the current account of each of these countries is stationary; however, when Breuer et al.'s (2001) Panel SURADF test is conducted, it is found that a unit root exists in the current account of 11 of the countries studied. These results have one extremely important policy implication for the 48 African countries studied: the current account deficit of most is sustainable, and thus signifying that those nations should have no incentive to default on their international debt.

Globalization, Financial Depth, and Inequality in Sub-Saharan Africa

OpenAIRE

Hisako KAI; Shigeyuki HAMORI

2009-01-01

This paper examines the relationship between globalization, financial deepening, and inequality in sub-Saharan Africa between 1980 and 2002. We provide the first detailed econometric analysis in this regard covering the entire sub-Saharan African region; such an analysis has hardly been conducted owing to the lack of relevant data. We find that while globalization deteriorates inequality, its disequalizing effect depends on the level of development of the country. Further, this paper confirms...

The proportion of the population that is > or = 60 years of age in sub-Saharan Africa (SSA) is increasing rapidly and is likely to constrain healthcare systems in the future. Nevertheless, the elderly are not a health policy priority for African countries. This paper reviews the nutritional and health status of older adults in SSA and their determinants. Literature was abstracted through the Medline, Google Scholar, and Dogpile databases using the following search terms: sub-Saharan Africa, older adults, nutrition, health. Findings showed that up to half (6-48%) of elderly Africans in SSA are underweight and almost a quarter (2.5-21%) are overweight, while 56% of older South Africans are obese. Low-quality diets contribute to poor nutritional status. Poverty, HIV/AIDS, and complex humanitarian emergencies are major determinants of undernutrition. Effective interventions need to consider socioeconomic, health, and demographic factors; social pensions may be the most cost-effective option for improving the health and nutritional status of the elderly in SSA.

Women's empowerment and ideal family size: an examination of DHS empowerment measures in Sub-Saharan Africa.

Upadhyay, Ushma D; Karasek, Deborah

2012-06-01

The Demographic and Health Survey (DHS) program collects data on women's empowerment, but little is known about how these measures perform in Sub-Saharan African countries. It is important to understand whether women's empowerment is associated with their ideal number of children and ability to limit fertility to that ideal number in the Sub-Saharan African context. The analysis used couples data from DHS surveys in four Sub-Saharan African countries: Guinea, Mali, Namibia and Zambia. Women's empowerment was measured by participation in household decision making, attitudes toward wife beating and attitudes toward refusing sex with one's husband. Multivariable linear regression was used to model women's ideal number of children, and multivariable logistic regression was used to model women's odds of having more children than their ideal. In Guinea and Zambia, negative attitudes toward wife beating were associated with having a smaller ideal number of children (beta coefficients, -0.5 and -0.3, respectively). Greater household decision making was associated with a smaller ideal number of children only in Guinea (beta coefficient, -0.3). Additionally, household decision making and positive attitudes toward women's right to refuse sex were associated with elevated odds of having more children than desired in Namibia and Zambia, respectively (odds ratios, 2.3 and 1.4); negative attitudes toward wife beating were associated with reduced odds of the outcome in Mali (0.4). Women's empowerment--as assessed using currently available measures--is not consistently associated with a desire for smaller families or the ability to achieve desired fertility in these Sub-Saharan African countries. Further research is needed to determine what measures are most applicable for these contexts.

In sub-Saharan Africa, many patients initiate antiretroviral therapy (ART) at CD4 cell counts much lower than those recommended in national guidelines. We examined program-level and contextual-level factors associated with low median CD4 cell count at ART initiation in populations initiating ART. Multilevel analysis of aggregate and program-level service delivery data. We examined data on 1690 cohorts of patients initiating ART during 2004-2008 in eight sub-Saharan African countries. Cohorts with median CD4 less than 111 cells/μl (the lowest quartile) were classified as having low median CD4 cell count at ART initiation. Cohort information was combined with time-updated program-level data and subnational contextual-level data, and analyzed using multilevel models. The 1690 cohorts had median CD4 cell count of 136 cells/μl and included 121,504 patients initiating ART at 267 clinics. Program-level factors associated with low cohort median CD4 cell count included urban setting [adjusted odds ratio (AOR) 2.1; 95% confidence interval (CI) 1.3-3.3], lower provider-to-patient ratio (AOR 2.2; 95% CI 1.3-4.0), no PMTCT program (AOR 3.6; 95% CI 1.0-12.8), outreach services for ART patients only vs. both pre-ART and ART patients (AOR 2.4; 95% CI 1.5-3.9), fewer vs. more adherence support services (AOR 1.6; 95% CI 1.0-2.5), and smaller cohort size (AOR 2.5; 95% CI 1.4-4.5). Contextual-level factors associated with low cohort median CD4 cell count included initiating ART in areas where a lower proportion of the population heard of AIDS, tested for HIV recently, and a higher proportion believed 'limiting themselves to one HIV-uninfected sexual partner reduces HIV risk'. Determinants of CD4 cell count at ART initiation in populations initiating ART operate at multiple levels. Structural interventions targeting points upstream from ART initiation along the continuum from infection to diagnosis to care engagement are needed.

2013-10-01

Full Text Available The study investigates Corporate Social Responsibility (CSR information disclosure practices of a sample of public enterprises operating in a less developing African country (i.e. Swaziland over the years 2008 and 2010. Corporate annual reports and other relevant documents were used to extract CSR disclosure information. The study used content analysis of CSR information appearing in the corporate reports. Content analysis was measured in accordance with number of words. The paper examines five major categories of CSR disclosure such as environmental performance and policies, human resources, community activities, fair business practices, and human rights. Findings show that the trend of increasing amounts of corporate social information disclosure amongst the enterprises from 2008 to 2010 has not increased significantly. Results show that human resources disclosure issues were greatest followed by community involvement and then by environmental related issues. There was no attempt to disclose human rights issues by the enterprises. This study contributes to the literature on CSR reporting practices by public enterprises in the context of less developing African countries.

Energy Security and Sub-Saharan Africa

Directory of Open Access Journals (Sweden)

Emily Meierding

2013-02-01

Full Text Available Published by Palgrave MacmillanOver the last decade the topic of energy security has reappeared on global policy agendas. Most analyses of international energy geopolitics examine the interests and behaviour of powerful energy-importing countries like the US and China. This chapter begins by examining foreign powers’ expanded exploitation of oil and uranium resources in Sub-Saharan Africa. It goes on to examine how energy importers’ efforts to enhance their energy security through Africa are impacting energy security within Africa. It assesses Sub-Saharan states’ attempts to increase consumption of local oil and uranium reserves. Observing the constraints on these efforts, it then outlines some alternative strategies that have been employed to enhance African energy security. It concludes that, while local community-based development projects have improved the well-being of many households, they are not a sufficient guarantor of energy security. Inadequate petroleum access, in particular, remains a development challenge. Foreign powers’ efforts to increase their oil security are undermining the energy security of Sub-Saharan African citizens.

McCarthy Carey F

2012-08-01

Full Text Available Abstract Background More than thirty-five sub-Saharan African countries have severe health workforce shortages. Many also struggle with a mismatch between the knowledge and competencies of health professionals and the needs of the populations they serve. Addressing these workforce challenges requires collaboration among health and education stakeholders and reform of health worker regulations. Health professional regulatory bodies, such as nursing and midwifery councils, have the mandate to reform regulations yet often do not have the resources or expertise to do so. In 2011, the United States of America Centers for Disease Control and Prevention began a four-year initiative to increase the collaboration among national stakeholders and help strengthen the capacity of health professional regulatory bodies to reform national regulatory frameworks. The initiative is called the African Health Regulatory Collaborative for Nurses and Midwives. This article describes the African Health Regulatory Collaborative for Nurses and Midwives and discusses its importance in implementing and sustaining national, regional, and global workforce initiatives. Discussion The African Health Profession Regulatory Collaborative for Nurses and Midwives convenes leaders responsible for regulation from 14 countries in East, Central and Southern Africa. It provides a high profile, south-to-south collaboration to assist countries in implementing joint approaches to problems affecting the health workforce. Implemented in partnership with Emory University, the Commonwealth Secretariat, and the East, Central and Southern African College of Nursing, this initiative also supports four to five countries per year in implementing locally-designed regulation improvement projects. Over time, the African Health Regulatory Collaborative for Nurses and Midwives will help to increase the regulatory capacity of health professional organizations and ultimately improve regulation and

2011-01-01

The northern sub-Saharan African (NSSA) region, bounded on the north and south by the Sahara and the Equator, respectively, and stretching from the West to the East African coastlines, has one of the highest biomass-burning rates per unit land area among all regions of the world. Because of the high concentration and frequency of fires in this region, with the associated abundance of heat release and gaseous and particulate smoke emissions, biomass-burning activity is believed to be one of the drivers of the regional carbon and energy cycles, with serious implications for the water cycle. A new interdisciplinary research effort sponsored by NASA is presently being focused on the NSSA region, to better understand the possible connection between the intense biomass burning observed from satellite year after year across the region and the rapid depletion of the regional water resources, as exemplified by the dramatic drying of Lake Chad. A combination of remote sensing and modeling approaches is being utilized in investigating multiple regional surface, atmospheric, and water-cycle processes, and inferring possible links between them. In this presentation, we will discuss preliminary results as well as the path toward improved understanding'of the interrelationships and feedbacks between the biomass burning and the environmental change dynamics in the NSSA region.

Full Text Available Abstract Background The implementation of the 58th World Health Assembly resolution on e-health will pose a major challenge for the Member States of the World Health Organization (WHO African Region due to lack of information and communications technology (ICT and mass Internet connectivity, compounded by a paucity of ICT-related knowledge and skills. The key objectives of this article are to: (i explore the key determinants of personal computers (PCs, telephone mainline and cellular and Internet penetration/connectivity in the African Region; and (ii to propose actions needed to create an enabling environment for e-health services growth and utilization in the Region. Methods The effects of school enrolment, per capita income and governance variables on the number of PCs, telephone mainlines, cellular phone subscribers and Internet users were estimated using a double-log regression model and cross-sectional data on various Member States in the African Region. The analysis was based on 45 of the 46 countries that comprise the Region. The data were obtained from the United Nations Development Programme (UNDP, the World Bank and the International Telecommunications Union (ITU sources. Results There were a number of main findings: (i the adult literacy and total number of Internet users had a statistically significant (at 5% level in a t-distribution test positive effect on the number of PCs in a country; (ii the combined school enrolment rate and per capita income had a statistically significant direct effect on the number of telephone mainlines and cellular telephone subscribers; (iii the regulatory quality had statistically significant negative effect on the number of telephone mainlines; (iv similarly, the combined school enrolment ratio and the number of telephone mainlines had a statistically significant positive relationship with Internet usage; and (v there were major inequalities in ICT connectivity between upper-middle, lower-middle and

Full Text Available The millennium development goals are now replaced by seventeen sustainable development goals. The emphasis of old goals was on improving water, sanitation, and child mortality conditions in developing countries. The study explored the major question about the association between different household environment conditions with child survival and health in Sub-Saharan African and South Asian countries in the current scenario. This paper estimated the risk of death, morbidity and under-nutrition among children living in households with the improved sources of water, sanitation and non-solid cooking fuel. Two sources of information explored in this study. First, data from World Health Statistics (WHS -2014 for all of the Sub-Saharan African and South Asian countries were used. Second, available standard Demographic and Health Survey performed in the countries of Sub-Saharan Africa and South Asia after 2010, included in the study. It resulted in inclusion of 15 countries which were Bangladesh (2011, Congo Republic (2013-14, Cote d'Ivoire (2011-12, Ethiopia (2011, Gambia (2013, Mali (2012-13, Mozambique (2011, Namibia (2013, Nepal (2011, Niger (2012, Nigeria (2013, Pakistan (2012-13, Sierra Leone (2013, Uganda (2011 and Zambia (2013.

Cox regression and logistic regression were used to estimate adjusted risks (odds ratio of child mortality and health outcomes using DHS surveys. The use of non-solid cooking fuel was very high in most of the Sub-Saharan African and South Asian Countries. There was a positive correlation between improving access to safe drinking water and sanitation. The exponential curve fitted well with child mortality and Household environmental indicators. The use of improved source of water and sanitation significantly related with the lower odds ratio of death, morbidity and under-nutrition among children aged 12-59 months. The risks were not

While sexual and gender-based violence (SGBV) is recognized as an important factor driving the HIV epidemic in sub-Saharan Africa, attitudes toward and prevalence of SGBV within sub-Saharan African military populations are unknown. Data on SGBV were collected from military service members of nine sub-Saharan African militaries. Attitudes related to SGBV and characteristics of those who commit and experience SGBV are reported. Data for 8815 service members (8165 men and 650 women) aged 18 years or older who voluntarily participated in the Seroprevalence and Behavioral Epidemiology Risk Surveys from 2009 to 2014 were included in this secondary data analysis. Data were collected on demographics, HIV prevalence, SGBV attitudes, and experiences. Descriptive and bivariate statistical analyses were performed. 5% of men and 9% of women reported experiencing SGBV, and 6% of men reported they had ever committed SGBV. Men and women who had experienced SGBV were significantly more likely to agree with negative gender attitudes toward SGBV, and the majority of those who reported experiencing SGBV reported that SGBV was committed by someone outside of the military. This is the first study to examine SGBV in sub-Saharan military populations during periods of limited conflict. It provides evidence that SGBV is experienced by both male and female service members at rates not typically found in previous research examining SGBV in other military populations. A better understanding of SGBV in sub-Saharan military service members is necessary to ensure appropriate services and interventions are part of the military infrastructure.

Since the Sahelian drought in the 1970s, climate variability in north tropical Africa has been the subject of intensive research focusing on the functioning of the Atlantic monsoon system as well as on past variations in rainfall from historical and natural archives. An "abrupt" climate change has been recorded off the Mauritanian coast at the end of the African Humid Period (AHP) 5500 years ago illustrating the onset of the modern climate regime [deMenocal et al., 2000]. At lake Yoa in NE Chad, [Kroepelin et al., 2008] report a "gradual" environmental change. Was this change abrupt or gradual, and amplified or not through vegetation change and feedbacks to the atmosphere is still the subject of debate. Here, we compile paleohydrological and palynological data between 10 and 28°N in the Sahara and Sahel with the purpose of understanding the response of the hydrological system and the vegetation cover to rainfall fluctuations from the onset of the AHP. Our data set is extracted from published studies. It is composed of 1651 dated samples from about 420 localities in the present day Sahara and Sahel. The occurrence of high and intermediate lake levels, fluvial terraces and wetlands as well as of dune edification are analysed with a 1000 yr period from 16 000 yrs BP to present. Clear trends are observed in the evolution of paleohydrological indicators versus time and latitude showing the progression of the centre of the distribution of humidity from south to north during the humid period and to the south after the AHP. The humidity maximum is observed with some temporal delay as compared to the June solar radiation maximum at 30°N. The reasons are investigated along the line of pure climate based processes and/or hydrological impacts. Further, the overall coherence among these signals is examined. Using climate simulations for different key periods in the Holocene, we investigate the relative impact of the insolation forcing, of the remnant ice sheet in the early

The West African sub-region comprises of sixteen different countries, which are as follows: Nigeria, Benin, Togo, Ghana, Code Ivore, Guinea, Guinea Bissau, Liberia, Sierra-Leone, Gambia, Senegal, Mauritania, Western Sahara, Mali, Burkina Faso and Niger Republique. Apart from Nigeria, Senegal and Ghana all the other remaining' countries are extremely poor and unviable. As a result of this the sub-region has been experiencing a lot of civil unrest, countries like Liberia, Sierra Leon and Code Ivore have been experiencing civil wars since the early 1990s. In addition to the already existing problems of trafficking in drugs, arms, humans and weaponry trade within the sub-region. Today the sub-region is experiencing the coming of a new evil deal called 'Trade in radio active waste'; which involves the transporting Of radioactive wastes from the developed countries to it's waste bin in West Africa, where it is unsafely buried after collecting millions of dollars from It's original owners. Recent statistics have revealed that most of the people involved in the evil businesses of trafficking in drugs, human, arms and trading in weaponry, are diverting in to the so called evil business of 'Trade in Radioactive waste' because this new illegal trade financially exceeds the rest of the above listed evil businesses

Effective implementation and sustainability of quality laboratory programmes in Sub-Saharan Africa relies on the development of appropriate staff retention strategies. Assessing the factors responsible for job satisfaction and retention is key for tailoring specific interventions aiming at improving the overall impact of health programmes. A survey was developed to assess these factors among 224 laboratorians working in the laboratory programme the University of Maryland implemented in seven Sub-Saharan African countries. Lack of professional development was the major reason for leaving the previous job for 28% of interviewees who changed jobs in the past five years. Professional development/training opportunities was indicated by almost 90% (195/224) of total interviewees as the most important or a very important factor for satisfaction at their current job. Similarly, regular professional development/opportunities for training was the highest rated incentive to remain at their current job by 80% (179/224). Laboratory professionals employed in the private sector were more likely to change jobs than those working in the public sector (P = 0.002). The findings were used for developing specific strategies for human resources management, in particular targeting professional development, aiming at improving laboratory professionals within the University of Maryland laboratory programme and hence its long-term sustainability.

2017-12-01

Full Text Available Several African countries have recently introduced or are currently introducing the HPV vaccine, either nationwide or through demonstration projects, while some countries are planning for introduction. A collaborative project was developed to strengthen country adolescent immunisation programmes and health systems in the African Region, addressing unique public health considerations of HPV vaccination: adolescents as the primary target group, delivery platforms (e.g. school-based and facility based, socio-behavioural issues, and the opportunity to deliver other health interventions alongside HPV vaccination.Following a successful “taking-stock” meeting, a training programme was drafted to assist countries to strengthen the integration of adolescent health interventions using HPV vaccination as an entry point. Two workshops were conducted in the Eastern and Southern African Regions. All countries reported on progress made during a final joint symposium.Of the 20 countries invited to participate in either of the workshops and/or final symposium, 17 countries participated: Angola, Botswana, Ethiopia, Kenya, Malawi, Mauritius, Mozambique, Namibia, Rwanda, Seychelles, South Africa, South Sudan, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe. Countries that are currently implementing HPV vaccination programmes, either nationally or through demonstration projects, reported varying degrees of integration with other adolescent health interventions. The most commonly reported adolescent health interventions alongside HPV vaccination include health education (including sexually transmitted infections, deworming and delivering of other vaccines like tetanus toxoid (TT or tetanus diphtheria (Td.The project has successfully (a established an African-based network that will advocate for incorporating the HPV vaccine into national immunisation programmes; (b created a platform for experience exchange and thereby contributed to novel ideas of

HIV-related stigma is associated with increased risk-taking behavior, reduced uptake of HIV testing, and decreased adherence to antiretroviral therapy (ART). Although ART scale-up may reduce HIV-related stigma, the extent to which levels of stigma in the general population have changed during the era of ART scale-up in sub-Saharan Africa is unknown. Social distance and anticipated stigma were operationalized using standard HIV-related stigma questions contained in the Demographic and Health Surveys and AIDS Indicator Surveys of 31 African countries between 2003 and 2013. We fitted multivariable linear regression models with cluster-correlated robust standard errors and country fixed effects, specifying social distance or anticipated stigma as the dependent variable and year as the primary explanatory variable of interest. We estimated a statistically significant negative association between year and desires for social distance (b = -0.020; P stigma (b = 0.023; P stigma in the general population increased despite a decrease in social distancing toward people living with HIV. Although ART scale-up may help reduce social distancing toward people living with HIV, particularly in high-prevalence countries, other interventions targeting symbolic or instrumental concerns about HIV may be needed.

Background. A group A meningococcal conjugate vaccine (PsA-TT) was developed specifically for the African “meningitis belt” and was prequalified by the World Health Organization (WHO) in June 2010. The vaccine was first used widely in Burkina Faso, Mali, and Niger in December 2010 with great success. The remaining 23 meningitis belt countries wished to use this new vaccine. Methods. With the help of African countries, WHO developed a prioritization scheme and used or adapted existing immunization guidelines to mount PsA-TT vaccination campaigns. Vaccine requirements were harmonized with the Serum Institute of India, Ltd. Results. Burkina Faso was the first country to fully immunize its 1- to 29-year-old population in December 2010. Over the next 4 years, vaccine coverage was extended to 217 million Africans living in 15 meningitis belt countries. Conclusions. The new group A meningococcal conjugate vaccine was well received, with country coverage rates ranging from 85% to 95%. The rollout proceeded smoothly because countries at highest risk were immunized first while attention was paid to geographic contiguity to maximize herd protection. Community participation was exemplary. PMID:26553672

2007-01-01

Countries in sub-Saharan Africa are some of the poorest and least developed in the world, with deplorable health and education levels. One way intended to promote better living standards in this region has been through development aid. This study examines the determinants of multilateral aid inflows to sub-Saharan Africa to determine whether it is directed to the least developed countries. I use panel data about 22 countries in sub-Saharan Africa from the 1995-2004 period to estimate a regres...

Background and Objectives Serologic screening for the major transfusion transmissible viruses (TTV) is critical to blood safety and has been widely implemented. However, actual performance as measured by proficiency testing has not been well studied in Sub-Saharan Africa. Therefore, we conducted an external quality assessment of laboratories engaged in transfusion screening in the region. Materials and Methods Blinded test panels, each comprising 25 serum samples that were pedigreed for HIV, HBsAg, HCV and negative status, were sent to participating laboratories. The panels were tested using the laboratories’ routine donor screening methods and conditions. Sensitivity and specificity were calculated and multivariable analysis was used to compare performance against mode of testing, country and infrastructure. Results A total of 12 African countries and 44 laboratories participated in the study. The mean (range) sensitivities for HIV, HBsAg and HCV were 91.9% (14.3-100), 86.7% (42.9-100) and 90.1% (50-100), respectively. Mean specificities for HIV, HBsAg and HCV were 97.7%, 97% and 99.5% respectively. After adjusting for country and infrastructure, rapid tests had significantly lower sensitivity than enzyme immunoassays (EIA) for both HBsAg (p<0.0001) and HCV (p<0.05). Sensitivity also varied by country and selected infrastructure variables. Conclusion While specificity was high, sensitivity was more variable and deficient in a substantial number of testing laboratories. These findings underscore the importance of proficiency testing and quality control, particularly in Africa where TTV prevalence is high. PMID:25052195

Increasing women's status and male involvement are important strategies in reducing preventable maternal morbidity and mortality. While efforts to both empower women and engage men in maternal health care-seeking can work synergistically, in practice they may result in opposing processes and outcomes. This study examines whether a woman's empowerment status, in sum and across economic, socio-familial, and legal dimensions, is associated with male partner accompaniment to antenatal care (ANC). Women's empowerment was measured based on the sum of nine empowerment items in the 2010-2011 Demographic and Health Surveys in eight sub-Saharan African countries: Burkina Faso (n = 2,490), Burundi (n = 1,042), Malawi (n = 1,353), Mozambique (n = 414), Rwanda (n = 1,211), Senegal (n = 505), Uganda (n = 428) and Zimbabwe (n = 459). In cross-sectional analyses, bivariate and multivariable logistic regressions models were used to examine the odds of male partner accompaniment to ANC between women with above-average versus below-average composite and dimensional empowerment scores. In the majority of countries, male accompaniment to ANC was not uncommon. However, findings were mixed. Positive associations in women's composite empowerment and male involvement were observed in Burkina Faso (OR = 1.27, 95% CI: 1.08, 1.50) and Uganda (OR = 1.53, 95% CI: 1.00-2.35), and in the economic empowerment dimension in Burkina Faso (OR = 1.24, 95% CI: 1.05-1.47). In Malawi, significant negative associations were observed in the odds of male accompaniment to ANC and women's composite (OR = 0.77, 95% CI: 0.62-0.97) and economic empowerment scores (OR = 0.75, 95% CI: 0.59-0.94). No significant differences were observed in Burundi, Mozambique, Rwanda, Senegal, or Zimbabwe. Women's empowerment can be positively or negatively associated with male antenatal accompaniment. Male involvement efforts may benefit from empowerment initiatives that promote women's participation in social and economic spheres

The debate between pro- and anti-international adoption advocates relies heavily on rhetoric and little on data analysis. To better understand the state of orphans and potential adopters in this debate, we utilize the National Survey of Family Growth (NSFG) and the Demographic and Health Surveys (DHS) to study who adopts internationally and the status of orphaned children in sub-Saharan Africa. According to NSFG data adopters are church going, highly educated, stable families aware of the challenges faced by international adoption, with high rates of infertility and rates of child abuse half the population average. According to the DHS data, orphans in sub-Saharan Africa suffer from significantly higher deprivation, reduced schooling and increased levels of stunting and underweight reported than their cohort. Using this data, we estimate conservatively that that 1 50 000 orphans from our sample of sub-Saharan African countries died from their 5-year birth cohort. Given the large number of families seeking to adopt and the high number of orphan deaths, it seems counterproductive to restrict international adoptions given the significantly lower risks faced by children in adopted families compared with remaining orphaned. © The Author 2015; all rights reserved.

Rheumatic valve disease, a consequence of acute rheumatic fever, remains endemic in developing countries in the sub-Saharan region where it is the leading cause of heart failure and cardiovascular death, involving predominantly a young population. The involvement of the mitral valve is pathognomonic and mitral surgery has become the lone therapeutic option for the majority of these patients. However, controversies exist on the choice between valve repair or prosthetic valve replacement. Although the advantages of mitral valve repair over prosthetic valve replacement in degenerative mitral disease are well established, this has not been the case for rheumatic lesions, where the use of prosthetic valves, specifically mechanical devices, even in poorly compliant populations remains very common. These patients deserve more accurate evaluation in the choice of the surgical strategy which strongly impacts the post-operative outcomes. This report discusses the factors supporting mitral repair surgery in rheumatic disease, according to the patients' characteristics and the effectiveness of the current repair techniques compared to prosthetic valve replacement in developing countries.

The trade winds that blow along the Atlantic coast from Morocco to Senegal represent one of the the largest and most productive wind potentials available on earth. Because of the erratic nature of winds however, wind electricity cannot be integrated locally on any significant scale, unless mechanisms are developed for storing these intermittent renewable energies. Developing distributed wind energy solutions feeding into smaller electricity markets are essential for solving energy access issues and enabling the development of a local, viable renewable energy industry. These may be critical to address the region's economic challenges currently under pressure from Sub-Saharan migrant populations. Windelectrolysis for the production of hydrogen can be used in grid stabilization, as power storage, fuel or chemical feedstock in specific industries. The objective of the NATO SfP 'Sahara Trade Winds to Hydrogen' project is to support the region's universities through an applied research framework in partnership with industries where electrolysis applications are relevant. By powering two university campuses in Morocco and Mauritania with small grid connected wind turbines and 30 kW electrolyzers generating hydrogen for power back-up as part of ''green campus concepts'' we demonstrated that wind-electrolysis for the production of hydrogen could absorb larger quantities of cheap generated wind electricity in order to maximize renewable energy uptakes within the regions weaker grid infrastructures. Creating synergies with local industries to tap into a widely available renewable energy source opens new possibilities for end users such as utilities or mining industries when processing raw minerals, whose exports generates key incomes in regions most exposed to desertification and climate change issue.

In sub-Saharan Africa, it is estimated that 215 million people continue to engage in open defecation. This practice facilitates the transmission of diarrheal diseases - one of the leading causes of mortality in children under 5 in sub-Saharan Africa. The main purpose of this study is to: estimate changes in open defecation prevalence between 2005 and 2010 across countries in sub-Saharan Africa; examine the association between national level indices and changes in open defecation prevalence; and assess how many countries can achieve 'open defecation free status' by 2015. After applying selection criteria, this study analyzed country-level data for 34 sub-Saharan African countries. Seven country-level indices were collected: 1) presence of a national sanitation policy; 2) budget line for sanitation; 3) budget allocated to sanitation; 4) annual per capita GDP; 5) GDP growth; 6) implementation of total sanitation approaches; and 7) per capita aid disbursement for water supply and sanitation. The relationships between these country-level indices and the change in open defecation from 2005 to 2010 were investigated using Wilcoxon Signed-Rank test and Spearman's rank correlation test. Only 3 countries (i.e. Ethiopia, Angola and Sao Tome and Principe) decreased open defecation by 10% or more between 2005 and 2010. No significant associations were observed between the change in open defecation prevalence and all of national level indices except per capita aid disbursement. Per capita aid disbursement for water and sanitation was positively associated with a reduction in open defecation (p-value = 0.02) for a subset of 29 low-income countries from 2005 to 2010. Only one country in our analysis, Angola, is on track to end open defecation by 2015 based on their performance between 2000 and 2010. Most of the national level indices, including a country's economic status, were not associated with the change in the open defecation prevalence. Based on current trends, the goal
