Governance,credit access and clean cooking technologies in Sub-Saharan Africa: Implications for energy transition

There is a global effort toward reducing or eliminating dirty fuels and technologies for cooking due to their severe health, environmental and economic implications. Reducing dirty energy usage requires an effective transition toward clean fuels and technologies for cooking. Effective governance and financial systems are needed to hasten the transition toward clean fuels and technologies for cooking. However, not much is known empirically about the role of access to credit and governance in the transition towards clean cooking technologies, especially in sub-Saharan Africa (SSA). This study, therefore, utilizes the two-step-dynamic system generalized method of moment estimator to investigate the effect of access to credit and governance on the adoption of clean cooking technologies in SSA. The findings indicate that access to credit and governance variables do not facilitate clean cooking technologies usage. The conditional analysis also reveals that the governance variables moderate the effect of access to credit to impede the adoption of clean fuels and technologies for cooking. The findings indicate that economic growth, education, and rural population drive the adoption of clean cooking technologies. Sensitivity checks show that the effect of access to credit and governance on clean fuels and cooking technologies usage differs among income and regional groups within SSA. We, therefore, argue that better financial and governance systems are required to hasten the transition toward clean fuels and technologies for cooking in SSA.     

Electronic Psychosocial Assessment Tool: Concept Development and Identification of Barriers to Successful Implementation

Information Communication Technologies (ICT) have resulted in positive outcomes in a range of clinical studies, however, most have not had widespread subsequent uptake, partly because they were not developed with all stakeholder requirements in mind. In the current study, we engaged stakeholders in the concept development stage of a project to transform a psychosocial assessment into an ICT-enabled format. By engaging the stakeholders in this early process we were able to identify a range of software functionalities that are likely to improve the applicability for users, as well as identify possible barriers to implementation.     

Virtual Shop Fronts: The Internet,Social Media,and Caribbean Civil Society Organisations

The Internet and, more recently, social media seem to promise the ability for non-state actors to more easily participate in domestic and international politics. ‘Global civil society’ can become ever more global with the help of these ‘new media’. This article uses the Caribbean Community (CARICOM) case to question the capacity of information and communication technologies (ICTs) to contribute positively to the insertion of developing country civil society organisations (CSOs) in a global civil society. Notwithstanding the possibilities that ICTs may open, Caribbean CSOs are not yet able to tap into these potentials effectively. Caribbean CSOs face resource constraints that ICTs alone may be unable to solve. However, the most significant hurdle that Caribbean CSOs face to elevating their work within global civil society is their relative powerlessness within global civil society. The article contends that this limited ability to be of influence is historically contingent and illustrates that hierarchies exist within global civil society that mirror asymmetries of power inherent in the state system.     

Implications of spatial and physical structures for ICT as a tool of urban management and development in Cameroon

Information and communication technologies (ICTs) hold enormous promise for development efforts in developing countries. However, the potential of ICTs remains untapped for reasons that are largely unknown in sub-Saharan Africa (SSA). This region has the lowest level of ICT penetration in the world. The need to understand impediments to ICT performance are therefore most urgent in this region. This paper seeks to address this need by identifying factors that inhibit the functionality of ICT as a tool for improving urban management. It analyzes two cities in the region, namely Douala and Yaounde, respectively Cameroon’s economic/cultural and politico-administrative capitals. The following three factors are shown to impede the functioning of ICT devices, hence urban management in these cities: colonial racial segregation policies, the colonial legacy of land use compartmentalization and the lack of unambiguous physical addresses for structures in the built environment. It is suggested that concerned authorities institute the following measures. 1] Establish an unambiguous addressing system reposed on the municipal governance structure and the country’s vehicle matriculation taxonomy. 2] Actively promote ICT as an element of national development. Finally, it presents some examples of efforts to improve ICT penetration and functionality from Senegal and South Africa.

Foresight Study on the Risk Governance of New Technologies: The Case of Nanotechnology

Technology‐led innovation represents an important driver of European economic and industrial competitiveness and offers solutions to societal challenges. In order to facilitate responsible innovation and public acceptance, a need exists to identify and implement oversight approaches focused on the effective risk governance of emerging technologies. This article describes a foresight study on the governance of new technologies, using nanotechnology as a case example. Following a mapping of the governance landscape, four plausible foresight scenarios were developed, capturing critical uncertainties for nanotechnology governance. Key governance elements were then stress tested within these scenarios to see how well they might perform in a range of possible futures and to inform identification of the strengths, weaknesses, opportunities, and threats for nanotechnology governance in Europe. Based on the study outcomes, recommendations are proposed regarding the development of governance associated with the responsible development of new technologies.
