Biological invasions can dramatically impact natural ecosystems and human societies. However, although knowledge of the economic impacts of biological invasions provides crucial insights for efficient management and policy, reliable syntheses are still lacking. This is particularly true for low income countries where economic resources are insufficient to control the effects of invasions. In this study, we relied on the recently developed "InvaCost" database – the most comprehensive repository on the monetised impacts of invasive alien species worldwide – to produce the first synthesis of economic costs of biological invasions on the African continent. We found that the reported costs of invasions ranged between US$ 18.2 billion and US$ 78.9 billion between 1970 and 2020. This represents a massive, yet highly underestimated economic burden for African countries. More alarmingly, these costs are exponentially increasing over time, without any signs of abatement in the near future. The reported costs were mostly driven by damage caused by invaders rather than expenses incurred for management. This trend was highly skewed towards a few regions (i.e. Southern and Eastern Africa) and activity sectors (i.e. agriculture) and incurred by a small number of invasive taxa (i.e. mainly three insect pests: Chilo partellus, Tuta absoluta, Spodoptera frugiperda). We also highlight crucial, large gaps in current knowledge on the economic costs of invasions that still need to be bridged with more widespread research effort and management actions across the continent. Finally, our study provides support for developing and implementing preventive measures as well as integrated post-invasion management actions at both national and regional levels. Considering the complex societal and economic realities in African countries, the currently neglected problem of biological invasions should become a priority for sustainable development.

There is an ever-growing need for clinically focused, culturally relevant research on which nurses can base their practice. However, there may not be a concurrent rise in efforts to strengthen infrastructure needed to promote research in developing and low-income countries. In such cases, nurse researchers must find innovative ways to address and overcome barriers to research. This article presents five exemplars of nurses conducting high-quality nursing research in resource-poor settings in southern and eastern Africa. Furthermore, it suggests strategies to address these barriers, such as piggybacking on larger studies, interdisciplinary collaboration, and partnership with influential stakeholders. These tactics may be used to increase research productivity elsewhere.

Policy Guidance

Having broadly stabilized inflation over the past two decades, many policymakers in sub-Saharan Africa are now asking more of their monetary policy frameworks. They are looking to avoid policy misalignments and respond appropriately to both domestic and external shocks, including swings in fiscal policy and spikes in food and export prices. In many cases they are finding current regimes—often characterized as ‘money targeting’—lacking, with opaque and sometimes inconsistent objectives, inadequate transmission of policy to the economy, and difficulties in responding to supply shocks. At the same time, little existing research on monetary policy is targeted to low-income countries. What do we know about the empirics of monetary transmission in low-income countries? (How) Does monetary policy work in countries characterized by a huge share of food in consumption, underdeveloped financial markets, and opaque policy regimes? (How) Can we use methods largely derived in advanced countries to answer these questions? And (how) can we use the results to guide policymakers? This book draws on years of research and practice at the IMF and in central banks from the region to shed empirical and theoretical light on these questions and to provide practical tools and policy guidance. A key feature of the book is the application of dynamic general equilibrium models, suitably adapted to reflect key features of low-income countries, for the analysis of monetary policy in sub-Saharan African countries.

Financing Infrastructure

Private sector investment opportunities in Africa’s infrastructure are huge. Regulatory reforms across African countries are identified as critical to the realization of the expected investment flows in the infrastructure sector. However, planners and policy makers need to note that there are infrastructure deficiencies in all subsectors with low income countries (LICs) in Africa facing the greatest challenge. Inefficiencies in implementing infrastructure projects account for USD 17 billion annually and improving the capacity of African countries will help minimize these costs. In this regard, the donor community must play a greater role in African LICs while innovative financing mechanisms must be the focus in the relatively richer countries of the continent. Traditional sources of financing infrastructure development remain important but private investment is critical in closing the current gaps. Countries need to devise mechanisms to exploit opportunities and avoid pitfalls in investing in infrastructure.

Introduction Recent debates surrounding the lagging covid-19 vaccination campaigns in low-income countries center around vaccine supply and financing. Yet, relatively little is known about attitudes towards covid-19 vaccines in these countries and in Africa in particular. In this paper, we provide cross-country comparable estimates of the willingness to accept a covid-19 vaccine in six Sub-Saharan African countries. Methods We use data from six national high-frequency phone surveys from countries representing 38% of the Sub-Saharan African population (Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, and Uganda). Samples are drawn from large, nationally representative sampling frames providing a rich set of demographic and socio-economic characteristics by which we disaggregate our analysis. Using a set of re-calibrated survey weights, our analysis adjusts for the selection biases common in remote surveys. Results Acceptance rates in the six Sub-Saharan African countries studied are generally high, with at least four in five people willing to be vaccinated in all but one country. Vaccine acceptance ranges from nearly universal in Ethiopia (97.9%, 97.2% to 98.6%) to below what would likely be required for herd immunity in Mali (64.5%, 61.3% to 67.8%). We find little evidence for systematic differences in vaccine hesitancy by sex or age but some clusters of hesitancy in urban areas, among the better educated, and in richer households. Safety concerns about the vaccine in general and its side effects emerge as the primary reservations toward a covid-19 vaccine across countries. Conclusions Our findings suggest that limited supply, not inadequate demand, likely presents the key bottleneck to reaching high covid-19 vaccine coverage in Sub-Saharan Africa. To turn intent into effective demand, targeted communication campaigns bolstering confidence in the safety of approved vaccines and reducing concerns about side effects will be crucial to safeguard the swift progression of vaccine rollout in one of the world's poorest regions.

It is now more than a decade since the acknowledgement of the health human resources crisis that exists in many low-income countries. During that decade much attention has focused on addressing the “pull” factors (e.g. developing voluntary international recruitment guidelines and bilateral agreements between recruiting and source countries) and on scaling up the supply of health professionals. Drawing on research conducted in two sub-Saharan African countries, we argue that a critical element in the human resources crisis is the poor working environments in these countries that not only continue to act as a strong “push” factor, but also impact on the motivation and performance of those who remain in their home countries. Unless attention is focused on improving work environments, the human resources crisis will continue in a vicious cycle leading to further decline in the health systems of low-income countries.

Abstract Background High Blood Pressure is the worldwide leading global burden of disease risk factor. In Sub-Saharan Africa, the number of adults with raised blood pressure has alarmingly increased from 0.59 to 1.13 billion between 1975 and 2015. Blood pressure-lowering medicines are cornerstone of cardiovascular risk reduction. Data on management of anti-hypertensive drugs in sub-Saharan Africa are squarce. Purpose Our study aims to describe antihypertensive drugs strategies in Africa. Methods We conducted a cross-sectional survey in urban clinics during outpatient consultation specialized in hypertension cardiology departments of 29 medical centers from 17 cities across 12 African countries (Benin, Cameroon, Congo, Democratic Republic of Congo, Gabon, Guinea, Ivory Coast, Mauritania, Mozambic, Niger, Senegal, Togo). Data were collected on demographics, treatment and standardized BP measures were made among the hypertensive patients attending the clinics. Country income was retrieved from the World Bank database. All analyses were performed through scripts developed in the R software (3.4.1 (2017–06–30)). Results A total of 2198 hypertensive patients (58.4±11.8 years; 39.9% male) were included. Among whom 2123 (96.6%) had at least one antihypertensive drug. Overall, 30.8% (n=653) received monotherapy and calcium-channel blockers (49.6%) were the most common monotherapy prescribed follow by diuretics (18.7%). Two-drug strategies were prescribed for 927 patients (43.6%). Diuretics and Angiotensin-converting enzyme inhibitors was the combination most frequently prescribed (33.7%). Combination of three drugs or more was used in 25.6% (n=543) of patients. The proportion of drugs strategies differed significantly according to countries (p<0.001), monotherapy ranged from 12.7% in Niger to 47.1% in Democratic Republic of the Congo (figure). Furthermore we observed a significantly difference of strategies between low and middle income countries (55.3% and 44.7% of monotherapy respectively) (p<0.001). According to hypertension grades 1, 2 and 3, the proportion of three-drugs or more combination was 25%, 28% and 34% in middle-income and lower in low-income countries (18%, 19% and 25%). Furthermore, Grade 3 hypertension in low income countries was still treated with monotherapy (36%) instead of 19% in middle income countries (p<0.01). Antihypertensive strategies by country Conclusion Our study described antihypertensive drugs use across 12 sub-Saharan countries, and identified disparities specific to the income context. Inequity in access to drugs combination is a serious barrier to tackle the burden of hypertension in Africa.

International Conventions

Little is known on current practices and challenges associated with the legal trade of medicines controlled under international conventions in low-income countries. This qualitative survey involved semi-structured interviews of stakeholders engaged in the trade of controlled medicines at a global level or at a country level in 3 African countries (Uganda, Kenya, Democratic Republic of the Congo). Nine interviews were conducted, including 3 international wholesalers, 2 relief organizations, 2 procurement officers, and 2 regulatory officers. Additionally, 4 other participants provided written information. All participants consistently reported that the current process of procuring controlled medicines in compliance with international conventions was long and complex given the number of administrative steps required for obtaining export and import authorizations, which are mandatory for both narcotic and psychotropic medicines. It may be difficult or impossible to obtain import authorizations from some health authorities in low-income countries because of long delays, mistakes in forms, absence or shortage of staff, or when annual national estimates are exceeded. The complexities of the trade of controlled medicines directly contribute to the lack of access to essential controlled medicines, both narcotics and psychotropics, in low-income countries.

Subject Cancer burden in Africa. Significance Cancer is a growing public health threat in low-income countries, including African states. With the increase in urbanisation, population growth and improving mortality rates, the World Health Organisation (WHO) estimates that by 2020, 16 million new cases of cancer will be diagnosed each year, with 70% of those in low-income countries. However, the rise in cancer rates has not been met with changes to aid funding. Global health priorities continue to emphasise infectious diseases, and African countries remain ill-equipped to prevent, diagnose or treat cancer. Impacts Rising consumption of processed foods in urban areas will contribute to an overall rise in non-communicable diseases. African countries are some of the fastest growing markets for tobacco companies as health awareness rises in traditional markets. Global brewers will enjoy significant market expansion in Africa, contributing to increased alcohol consumption. Despite the economic benefits, delayed childbearing and lower fertility in women is set to increase the incidence of breast cancer.

AbstractWe use new data on trade and production in 167 countries to infer estimates of trade costs for manufactured goods and agriculture for 1996‒2010. Trade costs are strongly declining in country income level. Among developing countries, only the upper middle income group has been successful in reducing trade costs faster than elsewhere in the world. Sub-Saharan African countries and low income countries remain subject to very high trade costs. Regional trade agreements, maritime transport connectivity, and trade facilitation performance are important determinants of trade costs.

Abstract Background Asthma is one of the most common chronic respiratory conditions in the world and is increasing in prevalence, particularly in Africa and other low-income countries. The disproportionately high numbers of premature deaths and severe or uncontrolled cases in many African countries are indicative of their inability to cope with a costly disease like asthma. Progress has, however, been made in understanding the complex and heterogeneous nature of the disease. The objective of this study will be to summarise the epidemiological literature on the nature of asthma in African countries. Methods We registered a study protocol for a scoping review. The review was designed following the Arksey and O’Malley framework. We will search PubMed/MEDLINE, African Journals Online (AJOL) and relevant grey literature (e.g. Google Scholar, EBSCOhost) from January 1990 onwards. Only primary epidemiological studies of asthma (e.g. frequency, disease mechanisms, associated risk factors and comorbidities) written in English and conducted in Africa will be included. Two reviewers will independently screen all citations, full-text articles and abstract data. Potential conflicts will be resolved through discussion. Findings will be reported using narrative synthesis and tabulation of the summaries. Discussion This scoping review will capture the state of the current epidemiological literature on asthma in African countries. Results will be published in a peer-reviewed journal. We anticipate this review will identify gaps and make recommendations for future areas of study. Scoping review registration Open Science Framework http://osf.io/n2p87/
