Abstract This paper compares two approaches to measuring subnational ethnolinguistic diversity in Sub-Saharan Africa, one based on censuses and large-scale population surveys and the other relying on the use of geographic information systems (GIS). The two approaches yield sets of regional fractionalization indices that show a moderately positive correlation, with a stronger association across rural areas. These differences matter for empirical analysis: in a common sample of regions, survey-based indices of deep-rooted diversity show a more strongly negative association with a range of development indicators relative to their highest-quality GIS-based counterparts.

Large scale population growth in sub-Saharan Africa makes it imperative to achieve an equivalent increase in food production in this area. It is also important that any increase be sustainable in the long-term, not causing lasting damage to local ecosystems. Recent advances in information technology make the successful diffusion of relevant expertise to farmers a more practical option than ever before. How this might be achieved is described in this paper, which considers the transfer of expertise in the diagnosis, treatment and management of trypanosomiasis in cattle. Using current technology, the combination of different software systems in one integrated hybrid system could allow the delivery of high quality, well focused information to the potential user.

Even in the broader African context, in which the chieftaincy has enjoyed a renaissance, the institution enjoys unusual power in Sierra Leone, where chiefs have strong representation and votes in national politics. Following more sedentary, land-based models of sovereignty in colonial times, the decade-long civil war saw the reemergence of alternative, more mobile models of the chieftaincy harkening back to precolonial times, in the face of massive population displacements. In the aftermath of war, when many chieftaincies were vacant, the possibility of replacing this hybrid hereditary-elected office with more democratic district councils was debated, but chiefs continue to be key members of these institutions, which rely on them for the collection of revenue and the administration of justice, particularly in rural areas. The chapter argues that the resurgence of this institution in sub-Saharan Africa is due to the ways in which chieftaincy stands for a more culturally legitimate form of decentralized governance, in contrast with the corrupt institutions of state governance. In Sierra Leone, the office’s continued identification with the local administration and allocation of land gives it renewed importance in the face of large-scale land deals with (and land grabs by) foreign investors. The expanding practice of conferring honorary chieftaincies to foreign agents of development contributes to the deterritorialization of the institution.

Mobile phone penetration rates have reached 63% in sub-Saharan Africa (SSA) and are projected to pass 70% by 2013. In SSA, millions of people who never used traditional landlines now use mobile phones on a regular basis. Mobile health, or mHealth, is the utilization of short messaging service (SMS), wireless data transmission, voice calling, and smartphone applications to transmit health-related information or direct care. This systematic review analyzes and summarizes key articles from the current body of peer-reviewed literature on PubMed on the topic of mHealth in SSA. Studies included in the review demonstrate that mHealth can improve and reduce the cost of patient monitoring, medication adherence, and healthcare worker communication, especially in rural areas. mHealth has also shown initial promise in emergency and disaster response, helping standardize, store, analyze, and share patient information. Challenges for mHealth implementation in SSA include operating costs, knowledge, infrastructure, and policy among many others. Further studies of the effectiveness of mHealth interventions are being hindered by similar factors as well as a lack of standardization in study design. Overall, the current evidence is not strong enough to warrant large-scale implementation of existing mHealth interventions in SSA, but rapid progress of both infrastructure and mHealth-related research in the region could justify scale-up of the most promising programs in the near future.

Abstract ‘Global land grabbing’ represents one of the hottest topics of debate within the areas of developmental and agricultural studies. However, this article claims that a narrow focus on the illegality and consequences of the ‘grabbing’, rather than on large scale investments in land (LaSIL) as a form of economic development which is inherently exclusionary, can be detrimental to the future of small-scale farmers. A short-term perspective overlooks the indirect consequences of industrialization, and legitimizes long-term exclusions and marginalization. Through past and present evidence, this paper demonstrates that LaSIL as competing projects will inevitably produce the abandonment of rural areas, the proletarianization of peasants, and the increase in social inequality, against any possibility for coexistence and harmonious cooperation.

Understanding patterns of genetic diversity is a crucial component of medical research in Africa. Here we use haplotype-based population genetics inference to describe gene-flow and admixture in a collection of 48 African groups with a focus on the major populations of the sub-Sahara. Our analysis presents a framework for interpreting haplotype diversity within and between population groups and provides a demographic foundation for genetic epidemiology in Africa. We show that coastal African populations have experienced an influx of Eurasian haplotypes as a series of admixture events over the last 7,000 years, and that Niger-Congo speaking groups from East and Southern Africa share ancestry with Central West Africans as a result of recent population expansions associated with the adoption of new agricultural technologies. We demonstrate that most sub-Saharan populations share ancestry with groups from outside of their current geographic region as a result of large-scale population movements over the last 4,000 years. Our in-depth analysis of admixture provides an insight into haplotype sharing across different geographic groups and the recent movement of alleles into new climatic and pathogenic environments, both of which will aid the interpretation of genetic studies of disease in sub-Saharan Africa.

AbstractThis paper explores the use of international governance frameworks as being one of the ways to regulate large-scale land acquisitions (LSLAs). LSLAs are currently flourishing in both developed and developing countries, in particular in the sub-Saharan Africa region. Although they can potentially have many positive impacts in rural areas, many LSLAs have been shown to mainly produce negative impacts in poor countries with weak national policy and institutional frameworks and poorly defined rights for rural people. To successfully regulate the occurrence of LSLAs and their impacts, it needs to be understood that LSLAs are more complex than they are usually portrayed as being. Some of the complexities pertain to water issues; provenience of investors; legality and legitimacy of acquisitions; as well as the diversity of actors and the people affected. Against this background, five international frameworks are looked at: human rights, voluntary international guidelines, international global water governance regimes and bi-/multilateral river treaties, and voluntary private standards and codes. The paper concludes that the frameworks reviewed provide valuable guidance regarding LSLAs, but no single approach can help in dealing with the multitude of actors, situations, and impacts of LSLAs. Even if they are considered collectively, they can tackle many but not all challenges. Yet, their implementation could substantially improve the process and the impact of LSLAs, including their refusal. A key question is how these frameworks are deployed at the local level. Some rely on translation into national laws and on their implementation, others try to establish a direct linkage between the international and the local level. It is of great interest to study how international frameworks trickle down to local policy arenas, how they are used by stakeholders, and how they are finally shaping conflicts at the local level and affecting their results. In particular, their potential for empowering poor stakeholders should be of interest for research and development.

Opportunities exist for adoption of precision agriculture technologies in all parts of the world. The form of precision agriculture may vary from region to region depending on technologies available, knowledge levels and mindsets. The current review examined research articles in the English language on precision agriculture practices for increased productivity among smallholder farmers in Sub-Saharan Africa. A total of 7715 articles were retrieved and after screening 128 were reviewed. The results indicate that a number of precision agriculture technologies have been tested under SSA conditions and show promising results. The most promising precision agriculture technologies identified were the use of soil and plant sensors for nutrient and water management, as well as use of satellite imagery, GIS and crop-soil simulation models for site-specific management. These technologies have been shown to be crucial in attainment of appropriate management strategies in terms of efficiency and effectiveness of resource use in SSA. These technologies are important in supporting sustainable agricultural development. Most of these technologies are, however, at the experimental stage, with only South Africa having applied them mainly in large-scale commercial farms. It is concluded that increased precision in input and management practices among SSA smallholder farmers can significantly improve productivity even without extra use of inputs.

Malaria still remains a challenging infection affecting the lives of several HIV infected pregnant women in sub-Saharan Africa. This study was undertaken to determine malarial infection in HIV infected pregnant women in relation to sociodemographic and obstetrical factors. The study also assessed relationship between malarial infection and haemoglobin level, CD4+ counts, and ART regimen, as well as predisposing risk factors that influenced occurrence of malarial infection in the women. Thick and thin blood smears were prepared and stained with Giemsa. Haemoglobin level was determined using a hematology analyzer, while the flow cytometry was used to measure CD4+ counts. Sociodemographic and obstetrical parameters were obtained through the administration of questionnaires. Of the 159 HIV infected pregnant women examined, 33.3% (59/159) had malarial infection. Malarial infection was significantly higher in pregnant women who were divorced, 40.24% (33/82) (χ2=5.72; P=0.05), were at their first trimester (4–12 weeks), 54.8% (17/31) (χ2=14.85; P=0.01), had CD4+ = [201–500 cells/μL], 42.42% (42/99) (χ2=10.13; P=0.00), and those that had severe anaemia (<8 dg/L), 100.00% (χ2= 45.75; P=0.00). However, risk factors that influenced the occurrence of malarial infection in the pregnant women were occupation (farming) (AOR=0.226; P=0.03), marital status (divorced) (AOR=2.80; P=0.02), gestation (first trimester) (AOR=0.33; P=0.00), haemoglobin level (Hb < 8 dg/L) (AOR=0.02; P=0.00), and CD4+ counts (low CD4+) (OR=0.40; P=0.05). The study reported endemicity of malaria in HIV infected pregnant women living in rural areas of Benue State, Nigeria. Malarial infection was higher in women that were divorced, and at their first trimester, had low CD4+ count, and had severe anaemia. Farming, divorce, gestation, severe anaemia, and low CD4+ counts were predisposing risk factors that influenced malaria occurrence in the HIV infected pregnant women. It is advocated that HIV infected pregnant women should be properly and thoroughly educated on malaria preventive measures in rural areas so as to avoid unpleasant effect of malaria during their pregnancies.

This paper presents the results of a three-year research project aimed at addressing the issue of water shortage and retention/collection in drought-affected rural areas of Sub-Saharan Africa. The project consisted in the design, construction, and the upgrade of existing barrages near Kita, the regional capital of Kayes in Mali. The effort was led by the Department of Architecture of Roma Tre University in partnership with the Onlus Gente d’Africa (who handled the on-the-ground logistics), the Department of Architecture of the University of Florence and the École Supérieure d’Ingénierie, d’Architecture et d’Urbanisme of Bamako, Mali. The practical realization of the project was made possible by Romagna Acque Società delle Fonti Ltd., a water utility supplying drinking water in the Emilia-Romagna region (Italy) that provided the financing as well as the operational contribution of AES Architettura Emergenza Sviluppo, a nonprofit association operating in the depressed areas of the world. The completion of the research project resulted in the replenishment of reservoirs and renewed presence of water in the subsoil of the surrounding areas. Several economic activities such as fishing and rice cultivation have spawned from the availability of water. The monitoring of these results is still ongoing; however, it is already possible to assess some critical issues highlighted, especially with the progress of the COVID-19 pandemic in the research areas.
