Understanding key vectors and vector-borne diseases associated with freshwater ecosystem across Africa: Implications for public health.

The emerging and re-emerging vector-borne diseases transmitted by key freshwater organisms have remained a global concern. As one of the leading biodiversity hotspots, the African ecoregion is suggested to harbour the highest number of freshwater organisms globally. Among the commonly found organisms in the African ecoregion are mosquitoes and snails, with a majority of their life cycle in freshwater, and these freshwater organisms can transmit diseases or serve as carriers of devastating diseases of public health concerns.

Macro problems from microplastics: Toward a sustainable policy framework for managing microplastic waste in Africa.

Microplastic pollution is a ubiquitous and emerging environmental and public health concern in Africa due to increased plastic production, product and waste importation, and usage. While studies on the environmental monitoring and characterization of microplastics demonstrated the urgent need for a drastic reduction in plastic waste generation, the effectiveness of the various regulatory and policy interventions implemented or proposed in Africa countries remains poorly understood. We critically examined policies, legislations, and regulations enacted to control microplastic pollution in Africa to develop a sustainable, harmonized framework for the coordinated reduction of plastic waste generation across Africa.

Another insight into the contamination levels at Ogoniland in Niger Delta, Nigeria, with focus on Goi Creek.

Environmental pollution arising from crude oil exploratory activities has adversely impacted both the living and non-living components of the ecosystem. An insight into the impact of such activities with focus on Goi Creek in Ogoniland was provided in this study. We generated reliable data for physicochemical, heavy metal, and total hydrocarbon levels in the creek via a total of 40 samples collected across 4 stations designated within the creek in a duration of 10 months.

Phylogeography and genetic diversity of the copepod family Cyclopidae (Crustacea: Cyclopoida) from freshwater ecosystems of Southeast Nigeria.

Background: Copepods are key components of aquatic ecosystems and can help regulate the global carbon cycle. Much attention has been paid to the species diversity of copepods worldwide, but the phylogeography and genetic diversity of copepods in Nigeria is unexplored.

Results: Using a mitochondrial cytochrome c oxidase subunit I marker, we preformed phylogenetic and phylogeographic analyses for Cyclopidae copepods in Southeast Nigeria.

A values-based approach for generating localized social indicators for use in sustainability assessment and decision-making: Test case of brownfield soft reuse in Nigeria.

Sustainable development is a global aim, aided in its application by the use of social, environmental and economic indicators for monitoring, planning, and assessment. However, several significant weaknesses are reported which reveal the need for improvement of the social indicators such as problems of being difficult to localize; to measure, and to be complete; being less commonly used; and thus, leading to assessments which are unbalanced across the three domains. Here we demonstrate that a values-based approach called WeValue InSitu, previously known to reliably 'crystallize' local shared values, can be successfully used as a bolt-on process to produce localized social indicators for direct insertion into the SuRF-UK process.
