Regional cooperation for mitigating energy poverty in Sub-Saharan Africa: a context-based approach through the tripartite lenses of access, sufficiency, and mobility

Persistent low electricity access continues to plague Sub-Saharan Africa (SSA) and has been made more obvious due to the precarious nature of adopted energisation schemes across the region. The absence of resilient electrification schemes within most countries in SSA portends grave danger for the region. Regional cooperation (like the integrated European Union (EU) electricity market) can guarantee stable, secure, and affordable electricity supply across regions when properly regulated. However, such a template as is obtainable in Europe may be impossible to replicate within SSA owing to the peculiar problems, local controversies and very wide variation in regional electrification statistics that exist within the region. This research work pertinently examines the power pools within SSA and argues that improved regional cooperation, especially in tackling the issue of energy poverty and achieving “universal energy access (SDG 7)”, should be pursued on the platform of national energy sufficiency. This argument draws extensively from the geopolitics within the region by different actors and the impact of national interests on regional cooperation. While we do not seek to oppose regional cooperation in electricity trading, we emphasize the need for nations within the region to strive for some level of national energy security through carefully crafted policies and road maps that resonate with their local realities. Regional cooperation should strive to standardise electricity access benchmarks and facilitate technology transfer through existing or improved instruments rather than pushing for more integrated electricity networks

Trace metals concentrations in fresh milk from dairy farms and stores: An assessment of human health risk.

Milk may be consumed daily for the supply of essential nutrients in the body, however, depending on the source, milk may contain different concentrations of trace metals. The present study investigated the presence of trace metals in fresh milk purchased from different dairy farms and stores to determine the possible health risks to humans. A total of 15 fresh milk samples were purchased from various dairy farms (7 fresh milk samples) and stores (8 milk samples). Trace metals in collected milk samples were determined using Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The human health risk was determined through the Hazard Quotient (HQ), Carcinogenic and Non-carcinogenic Risk. The results showed the presence of trace metals in fresh milk stores in the following order Pb>As>Se>Cr>Ni. The highest concentration for all the elements was recorded in Mg from milk purchased from the stores and ranged from 3.37±0.16 mg/L to 4.70±0.43 mg/L. In all the milk samples analyzed, levels of As, Pb, Se, Cr, and other elements were within the acceptable range recommended by the World Health Organization (WHO). Differences obtained in the concentrations of trace metals from both the purchased milk samples and those from the dairy farms were not significant (p<0.05). The Estimated Daily Intake (EDI) and Hazard Quotient Index showed no potential health risk for each trace metal indicating no health risk for the milk consumers at this stage. The traces of trace metals in the milk samples suggest the need for regular monitoring of trace metals in milk samples because prolonged exposure to these trace metals may seriously endanger the health of consumers
