AbstractLack of access to modern forms of energy hampers efforts to reduce poverty. The provision of electricity to off-grid communities is therefore a long-standing developmental goal. Yet, many off-grid electrification projects neglect mid- and long-term operation and maintenance costs. When this is the case, electricity services are unlikely to be affordable to the communities that are the project’s primary target. Here we show that, compared with diesel-powered electricity generation systems, solar photovoltaic systems are more affordable to no less than 36% of the unelectrified populations in East Asia, South Asia, and sub-Saharan Africa. We do so by developing geo-referenced estimates of affordability at a high level of resolution (1 km2). The analysis illustrates the differences in affordability that may be found at the subnational level, which underscores that electrification investments should be informed by subnational data.

The archaeology of Islam in Sub-Saharan Africa is remarkably diverse in relation to its material components, its geographical and chronological frameworks, and the life ways that were influenced by Islam, from settled and nomadic populations, peasants and kings, to merchants, farmers, warriors and townspeople. Islamisation processes were equally varied involving, for example, trade, proselytisation, jihad and prestige. Economically, new markets might be reached. Politically, the adoption of Arabic, of new forms of administration and of literacy could have a significant impact. Socially, material culture and ways of life could alter as manifest via diet and funerary practices, house types and settlement patterns. It is not possible to adequately summarise this diversity here.1 Instead emphasis will be placed upon selectively considering the evidence in order to indicate what archaeology can tell us about Islamisation processes in Africa, and to demonstrate the value and utility of archaeology for examining this Islamisation
