Towards sustainability: An assessment of an urbanisation bubble in China using a hierarchical - stochastic multicriteria acceptability analysis - Choquet integral method

Urbanisation bubbles have become an increasingly serious problem. Attention has been paid to the speed of urbanisation; however, the issue of quality has been neglected, particularly in the case of China. Therefore, the aim of this research is to evaluate China’s urbanisation bubbles by employing a hierarchical - stochastic multicriteria acceptability analysis (SMAA) - Choquet integral method. In order to highlight regional disparities, we measure the urbanisation bubbles at a provincial level. Our study aggregates the urbanisation bubble indices using the Choquet integral preference model, and considers the interactions between various indicators. Furthermore, robust ordinal regression and SMAA are applied to resolve the robustness issues associated with the entire set of weights assigned to the urbanisation bubble composite indicator. In addition, by employing a multiple criteria hierarchy process, the study aggregates urbanisation bubble indices not only at the comprehensive level, but also at the intermediate levels of the hierarchy. Our findings suggest that the ranking of urbanisation bubbles is positively related to the level of regional development. This study contributes to the evaluation of regional urbanisation and sustainable development

Security analysis for agroterrorism: applying the threat, vulnerability, consequence framework to developing countries

"We examine access to, use of, and participation in decisions on improved water supply in the Volta basin of Ghana, one of the first countries to introduce a community-based approach to rural water supply on a large scale. While 71 percent of the households interviewed have access to improved water, 43 percent of these continue to use unsafe sources as their main domestic water source. Our results indicate that quality perceptions and opportunity costs play an important role in households' choice of water source. The effect of prices and income levels on this choice differs according to the pricing system used. Given that supply characteristics such as the location and pricing system affect household decisions to use the improved source, households may try to influence these characteristics in their favor during the community decision-making process for the improved source. However, less than 40 percent of the households interviewed participated in decisions on location or technology. We argue that the decision whether to participate depends on three main factors: (i) the household's bargaining power, (ii) the potential benefits from influencing outcomes, and (iii) the cost of participation, (mainly opportunity cost of time). Our results indicate that bargaining power matters In some developing countries the potential exists for agroterrorism to cause widespread disruption through loss of sustenance, income and production. Defense of agriculture may also be problematic because of the lack stability and basic biosecurity infrastructure for the detection and prevention of diseases or invasive species. Currently new methodological approaches for terrorism risk assessments are being actively explored for resource prioritization. One such methodology for risk based allocation of resources is Threat, Vulnerability, and Consequence (TVC) Analysis. A qualitative application of the TVC framework is used to analyze the risk of agroterrorism in developing countries relative to industrialized countries. The analysis suggests that evidence exists to demonstrate general terrorist threats, vulnerability of agriculture and, depending on the country, potentially serious consequences arising from argoterrorism. Where specific threats emerge, action may be needed by the international community to strengthen biosecurity systems in developing countries through: increasing global cooperation, capacity building in monitoring, remediation and risk analysis technologies, and the dissemination of novel technologies for control of pests and diseases."

Uncertain Multi-Criteria Optimization Problems

Most real-world search and optimization problems naturally involve multiple criteria as objectives. Generally, symmetry, asymmetry, and anti-symmetry are basic characteristics of binary relationships used when modeling optimization problems. Moreover, the notion of symmetry has appeared in many articles about uncertainty theories that are employed in multi-criteria problems. Different solutions may produce trade-offs (conflicting scenarios) among different objectives. A better solution with respect to one objective may compromise other objectives. There are various factors that need to be considered to address the problems in multidisciplinary research, which is critical for the overall sustainability of human development and activity. In this regard, in recent decades, decision-making theory has been the subject of intense research activities due to its wide applications in different areas. The decision-making theory approach has become an important means to provide real-time solutions to uncertainty problems. Theories such as probability theory, fuzzy set theory, type-2 fuzzy set theory, rough set, and uncertainty theory, available in the existing literature, deal with such uncertainties. Nevertheless, the uncertain multi-criteria characteristics in such problems have not yet been explored in depth, and there is much left to be achieved in this direction. Hence, different mathematical models of real-life multi-criteria optimization problems can be developed in various uncertain frameworks with special emphasis on optimization problems

Energy Use Efficiency

Energy is one of the most important factors of production. Its efficient use is crucial for ensuring production and environmental quality. Unlike normal goods with supply management, energy is demand managed. Efficient energy use—or energy efficiency—aims to reduce the amount of energy required to provide products and services. Energy use efficiency can be achieved in situations such as housing, offices, industrial production, transport and agriculture as well as in public lighting and services. The use of energy can be reduced by using technology that is energy saving. This Special Issue is a collection of research on energy use efficiency

Water use efficiency and influence of management policies, analysis for the small-scale irrigation sector in South Africa

With the growing water scarcity, the need for more efficient water use has worldwide increased in importance. In addition, cost-recovery is now widely acknowledged as a cornerstone of sustainable water management. This research aims to contribute to improved water management in the small-scale irrigation sector in South Africa, which also faces these challenges. In a first analysis the economic production value of irrigation water was determined. Results show that without government subsidies on inputs, the profitability of many smallholders was low. Achieving full cost recovery therefore appears to be problematic for the current users. In the next part the concept of sub-vector efficiencies is introduced as a measure for water use efficiency. The analysis shows that smallholders fail to reach their overall technical efficiency levels when it concerns water use. Even using the current technologies the potential to reallocate irrigation water to other water demands is substantial. In a third part an innovative two-steps simulation model was developed to study the impact of water pricing. The model introduces a representation of the technology and smallholder efficiencies in a profit maximisation model. Farmers appear to be quite responsive to water charges and adjust their water use, even when the charge is relatively low. Pricing water can thus be used to provide incentives for efficiency improvement. However, the introduction of a water price is also shown to significantly decrease farm profit, particularly for smaller farms. The last part of the study investigates the impact of improving the water rights system in South Africa. Using a contingent ranking experiment the WTP of smallholders for specific interventions is estimated. The results show that farmers are prepared to pay considerably higher water prices if this is connected with advancements in the water rights system. This implies that such interventions would improve the efficiency of the small-scale irrigation sector. A higher WTP for water is also interesting in the light of the cost recovery, because it allows the government to increase water charges. In general, this research shows how economic analyses can be used to inform policy making to improve water management

HSE management system and efficiency evaluation of construction projects

The strategy of Belt and Road Initiative actively advocates the establishment of economic partnerships with countries along the belt and road, and makes infrastructure construction a field for preferential development. It provides good development opportunities for domestic and foreign engineering contracting enterprises. The "Strategic Implementation Guidance Document" mentions that infrastructure construction and operation should be green and efficient. However, most state owned engineering contracting enterprises do not attach importance to HSE management, which obviously affects the engineering efficiency and hinders the sustainable development of enterprises. However, China's engineering contracting enterprises pay less attention to HSE management, which obviously affects project efficiency and hinders the sustainable develop ment of enterprises. This study takes a typical large project contracting enterprise (Enterprise A) in China as the research object, adopts the SWOT analysis method, analyzes the weakness of project management at the organization level, and consummates th e organization level project HSE management system of the enterprise at the organization layer and the project layer. Through the enterprise interview, questionnaire design and investigation, this study puts forward the suitable indicators and methods of H SE management performance evaluation, and verifies the effectiveness of the methods through the empirical analysis of eight projects. Then, this study proposes incorporating the project HSE management performance into the comprehensive evaluation methods o f project efficiency. The empirical analysis shows that the HSE management system proposed in this study at the organization layer and at the project layer can improve the HSE management performance of the project. Project HSE management performance has a positive impact on project efficiency, that is, the more enterprises attach importance to project HSE management, the higher the degree of completion of project objectives. The above research results are helpful to improve project management system at the organizational level and enhance the competitiveness of project contracting enterprises.A estratégia da "Belt and Road Initiative" defende ativamente o estabelecimento de parcerias económicas com os países ao longo de uma determinada faixa e faz da construção de infraestruturas um campo preferencial para desenvolvimento. Este campo fornece boas oportunidades de desenvolvimento para as empresas de engenharia nacionais e estrangeiras. O "Documento de Orientação de Implementação Estratégica" menciona que a construção e operação de infraestruturas deve ser eficiente e sustentável. No entanto, a grande maioria das empresas públicas contratadas não atribuem a devida importância aos sistemas de gestão de saúde e segurança (HSE) o que, obviamente, afecta a eficiência da engenharia e dificulta o desenvolvimento sustentável das empresas. As empresas privadas chinesas de engenharia ignoram a gestão HSE o que, obviamente, afecta, também, a eficiência dos projetos de sustentabilidade das empresas. Neste trabalho foi considerada uma grande empresa Chinesa de contratação (Empresa A) na China como referência de pesquisa, que adota a análise swot, analisa as fraquezas na gestão de projetos ao nível da organização e consuma a gestão de projetos em HSE ao nível da organização e do projeto em si. Através de entrevistas, questionários e investigação, este projeto apresenta os indicadores e métodos a dequados de avaliação de desempenho e verifica a efetividade dos métodos através da análise empírica de oito projetos. Em suma, este projeto propõe incorporar métodos de avaliação da eficiência através dos indicadores de gestão do HSE. A análise empírica demonstrou que o sistema proposto de gestão HSE, ao nível da organização e de projeto, pode aumentar efetivamente a gestão de performance do HSE em projeto. A gestão da performance do projeto HSE teve um impacto positivo na eficiência do projeto, ou seja, quanto mais as empresas atribuirem importância à gestão de projetos HSE maior será o nível de conclusão dos objetivos sustentáveis do projeto. Os resultados deste projeto são úteis para melhorar o sistema de gestão de projetos ao nível organizacional e aum entar a competitividade das empresas na contratação de projectos

Sustainability in China: Bridging Global Knowledge with Local Action

China’s road to sustainability has attracted global attention. Since the “Reform & Opening Up” policy, China’s rapid pace of both urbanization and industrialization has made its being the second largest economy but meantime a heavy environmental price has been paid over the past few decades for addressing the economic developmental target. Today, as the biggest developing country, China needs to take more responsibilities for constructing its local ecological-civilization society as well as for addressing the global challenges such as climate change, resources scary and human beings well-fare; therefore, we need to have deeper understandings into China’s way to sustainability at very different levels, both spatially and structurally, concerns ranging from generating sustainable household livelihoods to global climate change, from developing technological applications to generate institutional changes. In this spirit, this publication, “Sustainability in China: Bridging Global Knowledge with Local Action” aims to investigate the intended and spontaneous issues concerning China’s road to sustainability in a combined top-down and bottom-up manner, linking international knowledge to local-based studies

Multinational Corporations, Technology Spillovers and Human Rights's Impacts on Developing Countries

This paper stems from the recognition that, in the current globalized world, the achievement of economic development goals is not necessarily accompanied by improved social conditions, or respect of people?s human rights more generally. Through their internal resources and capabilities, which often exceed those of many developing countries, Multinational Corporations (MNCs) can either positively or negatively condition their route towards development. While there are reported cases of positive economic effects generated by MNCs operations in developing countries, there is also plenty of evidence about MNCs involvement in human rights' abuses in these countries. To date, no scholarly research has analysed the factors that favour a positive (negative) MNC effect on host developing countries, by looking jointly at economic and human rights? impacts. This paper is a first attempt to take into account and integrate evidence coming from two distinct streams of literature, which have so far poorly interacted -- i.e. studies on MNCs' economic impact with a focus on technology spillovers; and studies on MNCs' human rights? impact on host developing countries.Multinational corporations, development, human rights, technology spillovers
