    Energy Access Scenarios to 2030 for the Power Sector in Sub-Saharan Africa

    In order to reach a goal of universal access to modern energy services in Africa by 2030, consideration of various electricity sector pathways is required to help inform policy-makers and investors, and help guide power system design. To that end, and building on existing tools and analysis, we present several ‘high-level’, transparent, and economy-wide scenarios for the sub-Saharan African power sector to 2030. We construct these simple scenarios against the backdrop of historical trends and various interpretations of universal access. They are designed to provide the international community with an indication of the overall scale of the effort required. We find that most existing projections, using typical long-term forecasting methods for power planning, show roughly a threefold increase in installed generation capacity occurring by 2030, but more than a tenfold increase would likely be required to provide for full access – even at relatively modest levels of electricity consumption. This equates to approximately a 13% average annual growth rate, compared to a historical one (in the last two decades) of 1.7%.Energy Access, Power System Planning, Sub-Saharan Africa

    Ecosystem services auctions: the last decade of research

    Get PDF
    ReviewAuctions offer potential cost-effectiveness improvements over other mechanisms for payments for ecosystem services (PES) contract allocation. However, evidence-based guidance for matching design to application is scarce and research priorities are unclear. To take stock of the current state of the art, we conducted a systematic review and thematic content analysis of 56 peer-reviewed journal articles discussing ES auctions published in the last decade. Auctions were approached from three overlapping perspectives: mechanism design, PES, and policy analysis. Five major themes emerged: (1) performance, including measures like cost-effectiveness and PES criteria like additionality; (2) information dynamics like price discovery and communication effects; (3) design innovations like risk-integrating and spatially coordinated mechanisms; (4) contextual variables like policy context and cultural values; and (5) participation factors. Additional attention from policymakers and continued efforts to coordinate research in this diverse and interdisciplinary subfield may be beneficialinfo:eu-repo/semantics/publishedVersio

    Current Developments in Services for People with Intellectual Disabilities

    [Taken from Executive Summary] This literature review is the culmination of the Saskatchewan Community Living Division jurisdictional study which began in the autumn of 2003. Following a brief survey of developments in providing services to people with intellectual disabilities (hitherto the People) for creating the questionnaire for this study, information was gleaned from the provinces and territories on their services. The CLD Jurisdictional Project was completed in the spring of 2005. Subsequently, a thorough search and examination of pertinent resources for serving this People and for policy development was conducted. From over 800 documents about 350 were selected for this literature review. The material is recorded in the following chapters: Public Consultation and Policy Development; Social Philosophy: the philosophical influence on contemporary social issues; Definition of disabilities; Needs assessment systems; Human Rights; Advocacy; Community services & Deinstitutionalization; Issues and Influences; Citizenship; Inclusion; Self-determination; Person-centered planning; Supports; Respite; Individualized funding; Canadian governmental initiatives; Provincial Services

    A formal model for measuring the different levels of IT-based Design and Construction Integration (ITDCI) in colleges and universities

    Get PDF
    Modern manufacturing processes are becoming more integrated and relying on measuring performance to better identify ways of improvement. The AEC industry is now moving in this direction through IT-based Design and Construction Integration (ITDCI). ITDCI is a collaborative knowledge-based activity in which each participant continuously and timely contributes and shares his/her knowledge to realize a specific goal, bonded by a unified and cohesive culture with the use of the supportive IT-tools. Executing the project in an ITDCI fashion requires the satisfaction of these conditions. This research developed a formal model that consists of 75 ITDCI mechanisms distributed over the different phases of the facility development process within colleges and universities to enable the knowledge transfer process and achieve the highest level of integration. The level of ITDCI involved in a particular project can be then measured by quantifying the number of ITDCI mechanisms introduced. The research methodology included the following activities: reviewing the related literature, developing and validating a scenario for the facility development process within typical colleges and universities through literature review and interviews, providing a definition for each phase of the process to be executed in an ITDCI fashion and finally identifying actions or mechanisms that have to be activated to obtain the highest level of ITDCI. The model was validated through an online survey that targeted the members of the Society of Colleges and Universities (SCUP) and a case study. WPI\u27s new East Hall residence facility was used as a case study to validate the model. This model is a significant contribution to the construction industry because it acts as a measuring tool to assess the corresponding level of ITDCI in the facility development process. It also helps to develop a common understanding among industry practitioners on what is required to achieve a desired level of ITDCI in their project. This comprehension would guide them to a better recognition of the benefits and consequences of each specific level of IT-based integration on their project outcomes. It will also enable them to execute more accurate cost/benefit analyses and eventually opt for the optimum ITDCI level. For future work, the model could be expanded to include other types of facilities, such as residential, healthcare and commercial facilities to achieve wider adoption within the AEC industry

    Evaluation of the main achievements of cohesion policy programmes and projects over the longer term in 15 selected regions (from 1989-1993 programme period to the present)

    Get PDF
    Against a background of inconclusive evidence of the results of EU Cohesion policy since 1989, the aim of this study has been to evaluate the main achievements of EU Cohesion policy programmes and projects and their effectiveness and utility over the longer term in 15 selected regions of the EU15. Specifically, the main objectives of the study were twofold: (i) to examine the achievements of all programmes co-financed by the ERDF and, where applicable, the Cohesion Fund, which have been implemented in the 15 selected regions from 1989 to 2012 (regional programmes and national programmes implemented in the regions); and (ii) to assess the relevance of programmes and the effectiveness and utility of programme achievement

    The achievements of cohesion policy: long-period evidence on the factors conditioning success and failure from 15 selected regions

    Get PDF
    This paper exploits a unique dataset on regional interventions in 15 beneficiary regions of the European Regional Development Fund over four programming periods (1989-2013) to examine empirically the processes and conditioning factors underpinning success and failure of such interventions over time and across space. Our core results suggest an elevated role for two key policy-design factors in maximising the achievements of Cohesion Policy: planning consistency (confluence between planned and realised expenditures), and alignment between regional needs and programme objectives. Although derived from a ‘selected’ sample, we claim that the obtained results may generalise well beyond the 15 regions studied here
