The South African government has named the transition towards a greener economy one of its priorities. Meanwhile it has developed a new multilevel integrated planning process, and announced a massive public infrastructure investment plan. The converging point of these three dynamics should be the integration of green infrastructure principles into the different plans as the foundation of the green transition. This paper uses a policy integration analytical framework to assess whether this convergence is in fact taking shape. It analyses the level of integration of green infrastructure principles into the different plans and suggests options to move the green infrastructure agenda forward. 相似文献

The effect of a number of dietary and synthetic chelating agents on the intestinal absorption of lead has been examined using the everted sac preparation and the tracer isotope 203Pb. All the agents examined increased lead transport into the serosal compartment. An explanation of the way in which these agents modify the model to describe lead transport is proposed. 相似文献

This paper analyses the differences between investment decisions for coal-fired power plants in Croatia and in Bosnia and Herzegovina (BiH). The long-run marginal cost (LRMC) of each plant is calculated based on a technical analysis that accounts for the important influences on overall project costs by combining a mathematical model and a simulation model. The former was used to calculate annual costs and the latter to predict power plant performance on the electricity market. This research offers insights about potential risks associated with power-plant investment with a particular focus on the regulatory framework and the relevance of participation in the European Union Emissions Trading Scheme (EU ETS) for costs, prices, and environmental impacts. 相似文献

This paper examines the impact of the physical environment and residents' perception and use of the environment settings on the social cohesiveness of disadvantaged communities in South Korea. Multiple regression and qualitative analysis were applied based on the data collected in four public rental housing estates in Seoul accommodating the lowest income households. This paper argues that social cohesiveness could be operationalised in shared norms and trust, attachment to housing estate and social networking. It was found that the characteristics of social cohesiveness were different across the same type of public rental housing estates, and that this variance was partly due to the different conditions of the physical environment. It was also found that a more positive perception of the physical environment and the more frequent use of facilities generally enhanced community cohesiveness. Desirable land use mix and housing types around the housing estates, preferable community facilities, housing block design and more effective refurbishment programmes within the estates were recommended. 相似文献

Building cities from scratch has continued unabated since the latter half of the twentieth century despite some of these planned cities achieving global infamy for their failures. These endeavors are, in part, due to a persistent belief by governments that newly constructed cities can set their nations on a fast path to the future. Today, challenges posed both by global climate change and increased urbanization have widened this platform from projects almost exclusively of developing nations to include those in the developed world. Today we talk of the eco-city, a local solution to a global crisis. If completion is successfully fast-tracked, the resultant eco-city will position its respective nation at the forefront of innovation in what is effectively a global race: the resultant city can be exported as a model both locally and globally. In this regard, the envisioning and building of Songdo in South Korea may not be unique. Songdo is a city underway on flat land created from wetland reclamation. As part of the Incheon Free Economic Zone (IFEZ), Songdo's development has benefited from opportunistic circumstances that has led to its pursuit of becoming a “Ubiquitous Eco-City.” The green infrastructure of the new city is to be enhanced by the provision of extra services that combine information and communication technologies as well as digital networks to ideally create harmony among the environment, society, and technology. Songdo, as planned, will position South Korea among a group of leading nations, and possibly at the forefront of new city development, potentially producing a model for export. 相似文献

The HIV/AIDS pandemic poses a substantial long‐term threat to economic development in South Africa. A questionnaire survey explored the perceptions of a sample of construction firms in the Western Cape regarding HIV/AIDS policy and treatment programmes. The findings show that there is no universal view about the long‐term threat of HIV/AIDS. Most organizations have awareness policies in place but prevention and treatment policies are less common. Treatment programmes are the least implemented of all intervention services due to insufficient resource capacity, the potential stigmatization of infected persons, and low take‐up rates. Despite an acknowledgement of the benefits flowing from mounting treatment programmes, doubt exists as to their financial viability. 相似文献

ABSTRACTFor many cities in the Global South, colonialism played a dominant role in shaping their urban form. The historical objective of planning in colonial mother-cities was dealing with poor health and living conditions, therefore a planning approach similar to that followed in post-war Britain would appear beneficial in post-colonial cities, characterized by environmental and physical infrastructure unable to cope with massive population growth. Urban growth management is a discourse born in an attempt to control the growing industrial city in the early twentieth century, and in recent years applied through instruments such as urban edges or growth boundaries to limit urban sprawl and encourage higher density urban development. In South Africa, the principles of compaction and urban growth management formed part of the post-apartheid planning agenda towards transforming the inefficient and fragmented landscape inherited from separate spatial development. Consequently, urban edges and urban growth boundaries formed key components of municipal spatial planning frameworks since the early 2000s. The purpose of this paper is to explore the origin and status of urban edges in three metropolitan municipalities in South Africa to aid in understanding of these spatial instruments in the south. 相似文献
