Sustainable development: Social outcomes of structural adjustments in a South Australian fishery     

Kate Brooks 《Marine Policy》2010

The assessment of sustainable development is a relatively recent advent in policy and the evaluation of industry structural adjustments. Although the elements of economic and environmental assessment have been relatively well developed and accepted, the effective inclusion of ‘social’ aspects in assessments of sustainable development are still being grappled with.  相似文献

Measuring Tourist’s Water Footprint in a Mountain Destination of Northwest Yunnan, China     

Luc HENS  Robert DE WULF 《山地科学学报》2011,8(5):682-693

Monitoring and minimizing tourist’s water consumption is essential for the sustainable development of mountain destinations in the world. However, available data and a generally accepted protocol on such measurement are still limited. This study uses water footprint accounting to quantify tourist’s water demand in the Liming valley, a World Heritage site and a rapidly growing tourism destination in Northwest Yunnan, China. Both the water for direct and indirect use is taken into account based on the consump...  相似文献   

Why are sustainable practices often elusive? The role of information flow in the management of networked human-environment interactions     

《Global Environmental Change》2023

Analyzing the spatial and temporal properties of information flow with a multi-century perspective could illuminate the sustainability of human resource-use strategies. This paper uses historical and archaeological datasets to assess how spatial, temporal, cognitive, and cultural limitations impact the generation and flow of information about ecosystems within past societies, and thus lead to tradeoffs in sustainable practices. While it is well understood that conflicting priorities can inhibit successful outcomes, case studies from Eastern Polynesia, the North Atlantic, and the American Southwest suggest that imperfect information can also be a major impediment to sustainability. We formally develop a conceptual model of Environmental Information Flow and Perception (EnIFPe) to examine the scale of information flow to a society and the quality of the information needed to promote sustainable coupled natural-human systems. In our case studies, we assess key aspects of information flow by focusing on food web relationships and nutrient flows in socio-ecological systems, as well as the life cycles, population dynamics, and seasonal rhythms of organisms, the patterns and timing of species’ migration, and the trajectories of human-induced environmental change. We argue that the spatial and temporal dimensions of human environments shape society’s ability to wield information, while acknowledging that varied cultural factors also focus a society’s ability to act on such information. Our analyses demonstrate the analytical importance of completed experiments from the past, and their utility for contemporary debates concerning managing imperfect information and addressing conflicting priorities in modern environmental management and resource use.  相似文献   

Geosites inventory of the northwestern Tabular Middle Atlas of Morocco   总被引：1，自引：0，他引：1

Across the northwestern Tabular Middle Atlas of Morocco there are many examples of landscapes, rocks and fossils that provide key evidence of a particular moment or period in Earth history. Such Earth heritage sites are important for educating the general public in environmental matters. They also serve as tools for demonstrating sustainable development and for illustrating methods of site conservation as well as remembering that rocks, minerals, fossils, soils, landforms form an integral part of the natural world. The significance of certain sites for aesthetic or tourism reasons is obvious. There are numerous geosites, which could contribute to effective exploitation of geotourism, often in conjunction with ecotourism. The strategy employed to such sites involves close consultation with all communities in the vicinity of the respective geosite and is not only aimed at tourism and education, but also at sustainable improvement of the infrastructure of the people of this area. Geological heritage sites, properly managed, can generate employment and new economic activities, especially in regions in need of new or additional sources of income.  相似文献

黄淮海平原水土资源利用的可持续性评价、开发潜力及对策   总被引：16，自引：11，他引：16  

吴凯  黄荣金 《地理科学》2001,21(5):390-395

黄淮海平原耕地顷均水资源量仅及全国平均水平的1／4，目前缺水率为19．3％，水资源利用可持续性综合评价指标属于中等偏下水平，为我国较为严重的缺水区，尤其是海河低平原区。土地资源利用对种植业而言，属于临界可持续状态，山前平原区指数值最低，有使耕地进一步向非农用方面转化的可能。2010年，本区水资源可供水量将比2000年增长22．4％，耕地面积仍能维持1998年水平。本区水土资源的区域匹配有明显的地区差异：山前平原区与海河低平原区水资源开发潜力不大，土地利用受缺水制约，水资源利用率已超过86％，平均可利用水资源量不足2500m^3/hm^2；但黄淮平原区和滨海低平原区水土资源均有较大的开发潜力，水资源利用率低于50％，平均可利用水资源量分别为3330m^3/hm^2和7020m^3/hm^2。本区水土资源利用的对策应为：积极开辟灌溉新水源（2010年外流域调水量和污水处理回用与微咸水利用量分别占可供水量的20．2％和4．9％），积极发展节水灌溉新技术，加快中低产地改造与高产农田的建设（中低产地改造后每公顷可增产粮食1950kg）以及实施稳定北部、提高中部、发展南部粮食生产的重点区域发展布局，以促进其农业和农村的可持续发展。  相似文献
