Climate change is a major contemporary global challenge. For developing countries like Nigeria, further challenge is poor power supply. Traditional power supply strategy has been through fossil-fuel based macrogrids. While most developed countries are replacing some macrogrids with renewable energy based microgrids, developing countries like Nigeria still maintain the status quo. This study intends to contribute to knowledge in the management of climate change and power supply in Nigeria through the adoption of microgrids as power supply strategy. In the study, data collected from a detached energy consuming community in Nigeria was used in a simulation using HOMER software for five different scenarios of energy resources combination, based on environmental impact and energy cost criteria. Results indicate that microgrids combining solar photovoltaic (SPV) and grid connection with battery energy storage (BES) are best in on-grid detached communities while microgrids combining diesel generators and SPV with BESare good for off-grid communities.

Climate change has emerged as one of the discussions where more is discussed and very less is implemented. People wait for actions to be taken by the government or multilateral organizations but seldom do they capture the developments going on. Several initiatives have been taken by individual countries as well as countries forming groups or conglomerates to tackle the challenges of climate change. This is true for BRICS as well. BRICS countries share the idea of climate protection but are sceptical of the policies passed by developed countries. BRICS as a forum of developing countries challenging the status quo of climate change policies has emerged to formulate its own climate change policies and initiatives in the light of BRICS discussions. The present study is aimed to capture the BRICS climate change policies and initiatives with a descriptive approach.

AbstractThe present article describes the main insights deriving from the papers collected in this special issue which jointly provide a ‘room with a view’ on some of the most relevant issues in climate policy such as: the role of uncertainty, the distributional implications of climate change, the drivers and applications of decarbonizing innovation, the role of emissions trading and its interactions with companion policies. While looking at different issues and from different angles, all papers share a similar attention to policy aspects and implications, especially in developing countries. This is particularly important to evaluate whether and to what extent the climate policies adopted thus far in developed countries can be replicated in emerging economies.

Drawing on the idea that countries are eligible to implement differentiated emission reduction policies based on their respective capabilities, some parties of UNFCCC attempt to weaken the principle of “Common but differentiated responsibilities(CBDR)” and impose carbon tariff on international trade. This initiative is in fact another camouflage to burden developing countries with emission cut obligation, which has no doubt undermined the development rights of developing countries. This paper defines Carbon Tariff as border measures that target import goods with embodied carbon emission. It can be import tariffs or other domestic tax measures that adjust border tax, which includes plain import tariffs and export rebates, border tax adjustment, emission quota and permit etc. For some developed countries, carbon tariffs mean to sever trade protectionism and to build trade barriers. Its theoretical arguments like “loss of comparative advantage”, “carbon leakage decreases environmental effectiveness” and “theoretical model bases” are pseudo-propositions without international consensus. Carbon tariff has become an intensively debated issue due to its duality of climate change and trade, but neither UNFCCC nor WTO has clarified this issue or has indicated a clear statement in this regard. As a result, it allows some parties to take advantage of this loophole and escape its international climate change obligation. Carbon tariff is an issue arising from global climate governance. To promote the cooperation of global climate governance and safeguard the social and economic development of developing countries, a fair and justified climate change regime and international trade institution should be established, and the settlement of the carbon tariff issue should be addressed within these frameworks. This paper argues that the international governance of carbon tariff should in cooperation with other international agreements; however, principles and guidelines regarding this issue should be developed under the UNFCCC. Based on these principles and guidelines, WTO can develop related technical operation provisions.

In developing countries and to a certain degree in developed countries too, either climate change (CC) consequences or drivers of CC are alien to the mindset of commoners, who after High School had with/without vocational skills entered the workforce. This deficit or ignorance can be rectified only by adding CC education in the school system. We present a school appropriate outline of CC learning content spanning Kinder Garten to High School. Adding CC content in school education is immensely warranted, as a large chunk of high schoolers annually joins the work force with or without vocational or skill training. Further, such a knowledge deficit among the generations of working class can be remedied only by providing appropriate and sufficient knowledge on CC consequences, etc., only through a structured adult education campaign.

Global food insecurity is becoming more severe under the threat of rising global carbon dioxide concentrations, increasing population, and shrinking farmlands and their degeneration. We acquired the ISI Web of Science platform for over 31 years (1988–2018) to review the research on how climate change impacts global food security, and then performed cluster analysis and research hotspot analysis with VosViewer software. We found there were two drawbacks that exist in the current research. Firstly, current field research data were defective because they were collected from various facilities and were hard to integrate. The other drawback is the representativeness of field research site selection as most studies were carried out in developed countries and very few in developing countries. Therefore, more attention should be paid to developing countries, especially some African and Asian countries. At the same time, new modified mathematical models should be utilized to process and integrate the data from various facilities and regions. Finally, we suggested that governments and organizations across the world should be united to wrestle with the impact of climate change on food security.

Background: Diabetes mellitus (DM) is considered one of the main causes of mortality, morbidity, and health care expenditures. Effectively treating this disease is of crucial importance and imposes a global challenge. The incidence of Type 2 DM (T2DM) is rapidly rising in both developing and developed countries. The Arab community in Israel is a distinct ethnic group with unique characteristics. Recently, this community has undergone major changes in its lifestyle, adopting the Westernized one, which could have caused an increase in the T2DM incidence rate. Objective: This review aims to shed light on various studies undertaken to explore the prevalence of diabetes and determine its current status in the Arab society of Israel, resting on previous and current data. It is presented to highlight the status of diabetes globally and to focus on its current situation in the Arab society of Israel, attempting to forecast its direction in the upcoming decade. Methods: Data were obtained from our previous comprehensive socio-economic and health cross-sectional surveys for successive periods from 2004 to 2017. These surveys were conducted on the Arab society of Israel by the Galilee Society. Results: Our results showed a progressive increase in the prevalence of T2DM from 3.4% to 7.6% in the Arab society of Israel. This trend is expected to continue rising in the coming decade, and based on our predictions, may exceed 12% in 2030. Conclusion: Substantial and practical health-related actions must be initiated to prevent an increasing number of adults from developing diabetes and its complications.

This chapter presents an overview of e-Government technological divide in developing countries. Technological divide here does not consist simply of telecommunications and computer equipment (i.e. ICTs), but it is also e-Readiness (i.e. the available capacity as indicated by workforce capacity to build, deploy, and maintain ICT infrastructure), ICT literacy (using digital technology, communication tools, and/or networks appropriately to access, manage, integrate, evaluate, and create information), e-Inclusion and/or e-Exclusion (i.e. no one is left behind in enjoying the benefits of ICT), etc., which are factors also necessary in order for people to be able to use and benefit from e-Government applications. Most of the currently published works on e-Government strategies are based on successful experiences from developed countries, which may not be directly applicable to developing countries. Based on a literature review, this chapter reveals the status of e-Government technological divide in developing countries and also underscores the challenges associated with e-Government in developing countries, thus bringing to the limelight the factors that influence the growth of the technological divide and different approaches that have been put in place to overcome the divide. In conclusion, this chapter advocates education and training, local content development, enhancing network infrastructure, and capacity building, among others, as ways of bridging the divide.

Developed countries usually have the means to take action, but face the challenges of politicians debating whether or not climate change is a priority. The case of developing countries is different: because even though they might want to take action toward climate change, most of these countries lack the means to do it, which are mainly having effective institutional arrangements and regulation.

Purpose – The purpose of this paper is to measure the competencies of libraries in Nigerian universities, identify constraints to their performance and recommend infrastructures and competencies required. Institutional accreditation has compelled academic libraries in Nigerian to improve their quality, competencies and performances for accountability. Design/methodology/approach – A questionnaire was the main instrument for data collection. The population of the study was all the university librarians in the 89 universities in Nigeria that the author selected from federal, state and private universities. Of the 81 sets of questionnaires emailed, 49 were returned, which represents a 60.5 per cent response rate and provides the working population of the study. Data were analysed using frequency tables, simple percentages and bar charts. Findings – The results indicate that academic libraries and librarians in Nigeria are competent in three key areas – educational roles, professional development and research. However, they are not very effective in the provision and use of library resources in cyberspace, adequate funding, collection development and information technology skills. The main constraints are: poor Internet penetration, low bandwidth, unreliable power supply and weak Internet proficiency. This paper suggests that adequate funding, benchmark performance and multi-skilling can serve as strategies against these constraints in developing regions. Practical implications – This study contributes to library staff assessment because it links strategic objectives to performance measures and associated long-term targets. It broadens issues which affect sustainable performance in academic libraries in Nigeria, as well as in Africa and other developing countries. Originality/value – While performance measurement is well established in developed countries, it is less or not so well established in Nigeria and other developing countries. The current research seeks to develop a performance measurement framework for academic libraries that is testable and expandable to Nigeria and the whole African context.

PurposeLife cycle assessment (LCA) has considerably contributed to increasing the environmental friendliness of buildings in developed countries. However, it is hard to find evidence on the application of LCA for buildings in developing countries; particularly, Sri Lanka. There is a lack of research to compare the status of LCA of buildings in developed countries vs developing countries. In this context, the purpose of this study aims to examine the status of LCA implementation for buildings between developed countries and Sri Lanka, a developing country.Design/methodology/approachThe exploratory research was adapted, and in-depth interviews were held with LCA professionals from Sri Lanka and developed countries, respectively.FindingsRelatively less attention has been paid to the implementation of LCA for buildings in Sri Lanka compared to the developed countries due to the time and effort required to collect life cycle inventory data and limited stakeholder understanding of the LCA. Hence, this study proposed improvements, including the development of LCA databases containing region-specific data and conducting programmes to raise stakeholders' awareness to address the gaps in Sri Lanka.Research limitations/implicationsThe identified LCA implementation process for buildings could be used as a guide for first-time LCA users, and it equally makes a valued reference for experienced practitioners.Originality/valueA limited number of the studies formulate a comparison between the LCA for building in developed countries and developing countries. This research attempts to address this knowledge gap.
