Recovering Mantle Memories from River Profiles

Researchers use a closed-loop modeling strategy to validate regional uplift patterns recorded in river profiles across the African continent.

Violent Resistance

Why do communities form militias to defend themselves against violence during civil war? Using original interviews with former combatants and civilians and archival material from extensive fieldwork in Mozambique, Corinna Jentzsch's Violent Resistance explains the timing, location and process through which communities form militias. Jentzsch shows that local military stalemates characterized by ongoing violence allow civilians to form militias that fight alongside the government against rebels. Militias spread only to communities in which elites are relatively unified, preventing elites from coopting militias for private gains. Crucially, militias that build on preexisting social conventions are able to resonate with the people and empower them to regain agency over their lives. Jentzsch's innovative study brings conceptual clarity to the militia phenomenon and helps us understand how wartime civilian agency, violent resistance, and the rise of third actors beyond governments and rebels affect the dynamics of civil war, on the African continent and beyond.

Epidemiology of West Nile virus in Africa: An underestimated threat

Background West Nile virus is a mosquito-borne flavivirus which has been posing continuous challenges to public health worldwide due to the identification of new lineages and clades and its ability to invade and establish in an increasing number of countries. Its current distribution, genetic variability, ecology, and epidemiological pattern in the African continent are only partially known despite the general consensus on the urgency to obtain such information for quantifying the actual disease burden in Africa other than to predict future threats at global scale. Methodology and principal findings References were searched in PubMed and Google Scholar electronic databases on January 21, 2020, using selected keywords, without language and date restriction. Additional manual searches of reference list were carried out. Further references have been later added accordingly to experts’ opinion. We included 153 scientific papers published between 1940 and 2021. This review highlights: (i) the co-circulation of WNV-lineages 1, 2, and 8 in the African continent; (ii) the presence of diverse WNV competent vectors in Africa, mainly belonging to the Culex genus; (iii) the lack of vector competence studies for several other mosquito species found naturally infected with WNV in Africa; (iv) the need of more competence studies to be addressed on ticks; (iv) evidence of circulation of WNV among humans, animals and vectors in at least 28 Countries; (v) the lack of knowledge on the epidemiological situation of WNV for 19 Countries and (vii) the importance of carrying out specific serological surveys in order to avoid possible bias on WNV circulation in Africa. Conclusions This study provides the state of art on WNV investigation carried out in Africa, highlighting several knowledge gaps regarding i) the current WNV distribution and genetic diversity, ii) its ecology and transmission chains including the role of different arthropods and vertebrate species as competent reservoirs, and iii) the real disease burden for humans and animals. This review highlights the needs for further research and coordinated surveillance efforts on WNV in Africa.

The Fight Against Climate Change From an Indigenous System Perspective

The 21st century has witnessed that climate change has become an acute daily agony. In Africa, to be specific, it has made the attainment of the Millennium Development Goals (MDGs) and Sustainable Development Goals a myth. It is argued that the implications of climate change are evident in numerous ways on the African continent: incessant floods, cyclones, droughts, and heat waves. These have introduced disastrous outcomes: a heightened threat of food security, inadequate water resource availability, diminished biodiversity, decline in human health viability, and increasing land degradation. At the centre of all this, a more robust understanding of climate change and appropriate palliatives is called for. In South Africa, conservation by the state and numerous stakeholders on the thorny issue of climate change has tended to favour and privilege Western scientific interpretations at the expense of the “indigenous” interpretations as informed by their indigenous epistemologies.

Homophobic Bullying in South African Schools

Homophobic bullying in schools is a global phenomenon. However, on the African continent, the phenomenon is rife because homosexuality is regarded to be un-African and is often linked to Western culture and colonial influence. These misconceptions about homosexuality have resulted in a culture of homophobia being inculcated into major structures of the society including schools. In this regard, this chapter aims to explore and describe the problem of homophobic bullying in South African schools. Particular attention is paid to cases of school-based homophobic bullying as primary sources of data as well as secondary sources of data from extant literature, textbooks, and journals articles. The chapter employs the Epstein Theory of Overlapping Spheres of Influence to proffer practical solutions and recommendations to address the problem of homophobic bullying in South African schools. These are school-, family-, and community-based solutions and recommendations based on the principles of social justice, inclusion, diversity, and equality.

Rainfall Variability and Trends over the African Continent Using TAMSAT Data (1983–2020): Towards Climate Change Resilience and Adaptation

This study reveals rainfall variability and trends in the African continent using TAMSAT data from 1983 to 2020. In the study, a Mann–Kendall (MK) test and Sen’s slope estimator were used to analyze rainfall trends and their magnitude, respectively, under monthly, seasonal, and annual timeframes as an indication of climate change using different natural and geographical contexts (i.e., sub-regions, climate zones, major river basins, and countries). The study finds that the highest annual rainfall trends were recorded in Rwanda (11.97 mm/year), the Gulf of Guinea (river basin 8.71 mm/year), the tropical rainforest climate zone (8.21 mm/year), and the Central African region (6.84 mm/year), while Mozambique (−0.437 mm/year), the subtropical northern desert (0.80 mm/year), the west coast river basin of South Africa (−0.360 mm/year), and the Northern Africa region (1.07 mm/year) show the lowest annual rainfall trends. There is a statistically significant increase in the rainfall in the countries of Africa’s northern and central regions, while there is no statistically significant change in the countries of the southern and eastern regions. In terms of climate zones, in the tropical northern desert climates, tropical northern peninsulas, and tropical grasslands, there is a significant increase in rainfall over the entire timeframe of the month, season, and year. This implies that increased rainfall will have a positive effect on the food security of the countries in those climatic zones. Since a large percentage of Africa’s agriculture is based only on rainfall (i.e., rain-fed agriculture), increasing trends in rainfall can assist climate resilience and adaptation, while declining rainfall trends can badly affect it. This information can be crucial for decision-makers concerned with effective crop planning and water resource management. The rainfall variability and trend analysis of this study provide important information to decision-makers that need to effectively mitigate drought and flood risk.

Socio-Economic and Political Impact of Pandemics in the African Continent and Regional Mechanisms to Mitigate it

Throughout the history of African societies, pandemics have claimed, in some instances more lives than warfare. Africa is susceptible to many pandemics. Given the state of underdevelopment amongst African nation-states characterised by low levels of education, poor health care facilities, lack of basic infrastructure, poverty, low levels of income, lack of skilled health care workers, and many more factors, it is not sufficiently equipped to handle pandemics that are life-threatening. Hence, it is prone to outbreaks of infectious diseases. Pandemics cause the socio-economic crisis, which in turn affects political stability. In the history of Africa, the Ebola disease, HIV/Aids, Cholera are some of the major diseases that have ravished nation-states in contemporary times. Now, just like other parts of the world, it has to deal with the Covid-19 pandemic that has far-reaching consequences. This article seeks to interrogate the nature and causes of major pandemics in the globe and the African continent and the steps taken to ameliorate these. It further examines the impact of pandemics on the socio-economic and political spheres of life in the continent.
