Until the late 1960s rural Hong Kong had an attractive rustic landscape and a small but active farming population. The recent widespread agricultural decline provided opportunities for urban-oriented activities to invade, mainly as open storage and workshops unsuitable in city areas. Rapid container-port expansion and cross-border China trade generate demands for cheap and accessible land for non-conforming uses (NCU). Rural development control and land-use planning are inherently weak, and formal provision for such uses is lacking. An unfavorable landmark court judgement allows landowners to degrade the countryside. The activities have caused acute environmental problems, telescoped into a small territory, including visual blight, pollution, drainage blockage, loss of wetland habitats, and increased flooding hazard. The distinction between urban and rural has been blurred in the destruction of the valuable countryside heritage. An interim legislative amendment fails to stop unauthorized conversion of farmland. In the long term, an integrated and comprehensive rural planning strategy to conserve inherent elements, as well as accommodating selected urban spillover in properly located and serviced sites, is needed.  相似文献

The British pride themselves on their long tradition of landscape management rooted in the aristocratic and landowning classes of the 18th and 19th centuries. The British also emphasize that the rise of modern pollution control began in the Victorian industrial era with the emergence of the national Inspectorates and the local Commissioners of Sewers. All these traditions are rooted in British social history, which was heavily influenced by class, power, and the changing shape of industrial and agricultural development. In modern Britain, affected by industrial recession, where concern over jobs and growth appears to dominate public and political attention, as well as public spending cuts that sap the morale and effectiveness of the major regulatory agencies, attitudes toward, and the execution of, environmental protection are undergoing a subtle but profound revolution. It is slowly but agonizingly being recognized that economic growth and social well-being cannot be disconnected from environmental processes and the limits these impose on management and technological intervention. A 21st century Britain will have to integrate conservation with development in order to survive.  相似文献

Sovereign financial disaster risk management: The case of Mexico   总被引:1,自引:0,他引:1  
In 2006, Mexico became the first transition country to transfer part of its public-sector natural catastrophe risk to the international reinsurance and capital markets. The Mexican case is of considerable interest to highly exposed transition and developing countries, many of which are considering similar transactions. Risk financing instruments can assure governments of sufficient post-disaster capital to provide emergency response, disaster relief to the affected population and repair public infrastructure. The costs of financial instruments, however, can greatly exceed expected losses, and for this reason it is important to closely examine their benefits and alternatives. This paper analyzes the Mexican case from the perspective of the risk cedent (the Ministry of Finance and Public Credit), which was informed by analyses provided by the International Institute for Applied Systems Analysis (IIASA). The rationale for a government to insure its contingent liabilities is presented along with the fiscal, legal and institutional context of the Mexican transaction. Using publicly available data, the paper scrutinizes the choice the authorities faced between two different risk-transfer instruments: reinsurance and a catastrophe bond. Making use of IIASA's catastrophe simulation model (CATSIM), this financial risk management decision is analyzed within the context of a public investment decision.  相似文献

Land‐acquisition strategies employed by conservation organizations vary in their flexibility. Conservation‐planning theory largely fails to reflect this by presenting models that are either extremely inflexible—parcel acquisitions are irreversible and budgets are fixed—or extremely flexible—previously acquired parcels can readily be sold. This latter approach, the selling of protected areas, is infeasible or problematic in many situations. We considered the value to conservation organizations of increasing the flexibility of their land‐acquisition strategies through their approach to financing deals. Specifically, we modeled 2 acquisition‐financing methods commonly used by conservation organizations: borrowing and budget carry‐over. Using simulated data, we compared results from these models with those from an inflexible fixed‐budget model and an extremely flexible selling model in which previous acquisitions could be sold to fund new acquisitions. We then examined 3 case studies of how conservation organizations use borrowing and budget carry‐over in practice. Model comparisons showed that borrowing and budget carry‐over always returned considerably higher rewards than the fixed‐budget model. How they performed relative to the selling model depended on the relative conservation value of past acquisitions. Both the models and case studies showed that incorporating flexibility through borrowing or budget carry‐over gives conservation organizations the ability to purchase parcels of higher conservation value than when budgets are fixed without the problems associated with the selling of protected areas.  相似文献

ABSTRACT

This paper has a quintessentially explorative character. It aims at identifying existing as well as potential (yet missing) links between the finance industry and local businesses that aspire to more sustainable economic practices. Building on the observation that green investments have been gaining weight in global investors’ strategies, we analyse how sustainable – in the most comprehensive sense of the word – green investments could ultimately be(come), when green assets are still managed according to the logic of “financialised finance”. This latter’s technologies of commodification, securitisation and derivatives-trading allegedly oppose alternative economic practices that pursue economic sustainability through social and environmental gains. In contrast, we investigate how the finance industry relates to alternative financial practices, products and organisations that offer sustainability-oriented financing services, – for example, regional banks, cooperatives and the like, – with a specific focus on green, social and solidarity businesses. Both approaches subscribe to apparently contradictory ideologies. We establish a beneficial dialogue between the opposing models of “green capitalism” and “alternative economies” so as to identify potential points of intersection. The context of Luxembourg’s local/regional economies provides a great opportunity to empirically access three levels of investigation: the private sector, the public sector and an international financial centre, a key facilitator for green finance, thus utilising insights from the concept of bricolage. Whilst supporters of Luxembourg’s emerging green finance profile recognise its positive impact on the small country’s national branding, in combination with economic stimuli, more critical commentators point to pure “green washing” effects.  相似文献

The international minerals industry continues to have a substantial investment shortfall. The widening exploration and mineral development gaps, not only in the lesser developed countries but also in the developed nations, are sowing the seeds for future mineral supply disruptions and conflicts. Mutuality of interests demands concerted initiatives, individual as well as collective, to reverse the investment trends established by international mineral finance and the multinational corporations in order to pave the way for secure mineral supplies in the future at acceptable prices.  相似文献

This paper looks at the use and effectiveness of the Site of Special Scientific Interest designation in three counties in the East Midlands region of the Nature Conservancy Council, namely Nottinghamshire, Northamptonshire and Cambridgeshire. Using unpublished sources within the NCC an analysis is made of the SSSI system in practice since its inception in 1949. A number of findings relating to weaknesses in the designation and the operation of the designation system emerge. Each of these findings is discussed in turn with the presentation of the appropriate evidence from the county case studies.  相似文献
