<abstract> <p>Access to clean energy is necessary for environmental cleanliness and poverty reduction. That notwithstanding, many in developing countries especially those in sub-Saharan Africa region lack clean energy for their routine domestic activities. This study sought to unravel the factors that influence clean energy accessibility in sub-Saharan Africa region. Clean energy accessibility, specifically access to electricity, and access to clean cooking fuels and technologies, were modeled as a function of income, foreign direct investment, inflation, employment and political regime for a panel of 31 sub-Saharan countries for the period 2000–2015. Regression analysis from fixed effect, random effect and Fully Modified Ordinary Least Squares show that access to clean energy is influenced positively by income, foreign direct investment, political regime and employment while inflation has some negative effect on its accessibility. The policy implications from the findings among other things include that expansion in GDP per capita in the sub-region shall be helpful in increasing accessibility to clean energy. Moreover, strengthening the democratic institutions of countries in the region shall enhance the citizens' accessibility to clean energy. Ensuring sustainable jobs for the citizens is necessary for access clean energy.</p> </abstract>

This paper estimates the economic impact of climate change on road infrastructure using the stressor-response methodology. Our analysis indicates that it could cumulatively (2020-2100) cost Ghana $473 million to maintain and repair damages caused to existing roads as a result of climate change (no adapt scenario). However, if the country adapts the design and construction of new road infrastructure, expected to occur over the asset's lifespan (adapt scenario), the total cumulative cost could increase to $678.47 million due to the initial costs of adaptation. This investment provides lower costs on a decadal basis later in the infrastructure lifespan. This creates the planning question of whether lower decadal costs in the future are a priority or if minimizing initial costs is a priority. The paper addresses this question through decadal and average annual costs up to the year 2100 for the ten regions, using the potential impacts of 54 distinct potential climate scenarios.
