Urban planning is commonly blamed for its failure to exert a positive influence on managing climate change impacts in urban Africa; yet little is known about planning agencies' perspectives on climate change-urban planning conundrum, and corresponding policy responses. It is in response to this gap, this paper explores agency perspectives and policy responses on the possibility and procedure for harnessing urban planning as a tool for managing climate change impacts in a Ghanaian city of Kumasi. ...

Private capital is required to urgently complement government's efforts to meet initial capital outlay in renewable energy investments. However, minimising the downside risks for a given return in such a venture presents valuation challenges, including the timing of such investments. Investment timing is therefore relevant to consider when making investments in utility-scale renewable energy technologies which require high initial capital. This study assesses the value of investment delay in renewable ...

A three-phase land use scenario (2000, 2007 and 2013) employing the “fix-changing” method was used to simulate the hydrology of the Olifants Basin. Changes in land uses were related to different hydrological responses through a multi-regression analysis to quantify the effects of land use changes. Results reveal that from 2000 to 2013, a 31.6% decrease ...

Under-reporting remains a challenge particularly in developing countries among healthcare professionals (HCPs) who are considered the primary stakeholders in the reporting of ADRs.

This study examines the rate of reporting as well as awareness, knowledge, ...
