Hydromorphological and socio-cultural assessment of urban rivers to promote nature-based solutions in Jarabacoa,Dominican Republic

In Latin America and the Caribbean, river restoration projects are increasing, but many lack strategic planning and monitoring. We tested the applicability of a rapid visual social–ecological stream assessment method for restoration planning, complemented by a citizen survey on perceptions and uses of blue and green infrastructure. We applied the method at three urban streams in Jarabacoa (Dominican Republic) to identify and prioritize preferred areas for nature-based solutions. The method provides spatially explicit information for strategic river restoration planning, and its efficiency makes it suitable for use in data-poor contexts. It identifies well-preserved, moderately altered, and critically impaired areas regarding their hydromorphological and socio-cultural conditions, as well as demands on green and blue infrastructure. The transferability of the method can be improved by defining reference states for assessing the hydromorphology of tropical rivers, refining socio-cultural parameters to better address river services and widespread urban challenges, and balancing trade-offs between ecological and social restoration goals.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01565-3.     

中国旅游业CO_2排放区域差异的空间分析

在旅游业节能减排形势严峻的背景下,深入研究中国旅游业CO_2排放问题,制定科学的区域节能减排政策已刻不容缓。本文首先运用"自下而上"法,估算了1993-2012年中国整体旅游业、旅游业各分部门、大陆各省区(不含西藏)旅游业CO_2排放量。在此基础上,对全国及三大地带旅游业CO_2排放的总体特征进行分析;利用Theil指数法分析了中国旅游业CO_2排放强度的区域差异、区域内差异和区域间差异;运用AreView软件对中国旅游业CO_2排放强度的省际差异进行直观图示。分析结果显示:1993-2012年,中国旅游业CO_2排放量从1 480.868×10~4t升至6 274.129×10~4t;全国及三大地带旅游业CO_2排放强度整体上呈现出先显著下降、再缓慢梯度下降的趋势;中国旅游业CO_2排放强度空间分布不均匀,东部地区旅游业CO_2排放强度低于中部和西部地区;中国旅游业CO_2排放强度的区域总体差异、区域间差异和区域内差异整体呈逐渐缩小的趋势,区域间差异对总体差异的贡献率为94%-98%,区域间差异占主导地位;中国旅游业CO_2排放强度省际差异明显,属于旅游业CO_2排放强度弱显著区的省区基本位于东部沿海地区,河北、湖南、河南、广西、甘肃和新疆等省区频繁出现在旅游业CO_2排放强度强显著区之列,因此上述省区应是中国旅游业CO_2未来节能减排的区域重点。据此提出差别化的CO_2减排对策:东部地区应通过技术改进和调整产业结构、能源消费结构来降低CO_2排放强度,并以此带动中部和西部地区旅游业节能减排;中部和西部地区应加强与东部地区合作,将提高能源使用率、降低CO_2排放强度作为旅游业减排工作的重点。

The Dual Model for Tourism Resource Productivity Improvement

For natural resource science, resource productivity studying is an important subject. But researches on tourism resource productivity are limited. The most significant influencing factor on tourism resource productivity is the potential market scale of tourist locations, and second most important influencing factor is the resource endowment. Regional urban population is significantly correlated with region tourist numbers, being the decisive factor of region potential tour market scale. In tourism development, the dual model should be adopted: on one hand to enhance tour spot attractiveness, on the other hand to cultivate the potential market by improving urbanization level and other means. In the situation of tourism development fever spreading, the dual model for improving tourism productivity helps to avoid the "Great Leap Forward" which means that too rapid tourism construction divorces from actual market demand.     

Sustainable Tourism Development Management of Local Cultural Landscapes

Abstract

Nowa days, ecological and cultural tourism, especially those ancient villages and towns in China, have attracted an increasing number of tourists because of their unique cultural features. However, rapid development of tourism brings economic benefits, but results in a series of problems that threaten further tourism development and protection of ancient towns, such as over-commercialization and tourism urbanization. Taking Longmen ancient town as an example, this paper presented a sustainable way of preserving and developing resources of ancient villages and towns. First, identify cultural features and the extent of ancient villages and towns, and find the approach through which a cultural landscape zoning can be applied. Second, define a cooperative function area to release the pressure on core areas and protect their authentic cultures by extending tourism space. Third, balance tourism development with traditional industries to enhance the sustainability of community economies.     

基于上海案例的大都市旅游容量及承载力研究

都市旅游容量和承载力问题是事关都市旅游可持续发展、和谐旅游环境建设的重大战略性命题。上海都市旅游发展跨入了由数量扩张向质量提升的重要转型发展期。面临警旅游容量问题的严峻挑战。都市旅游容量管理与调控是一项社会系统工程。实施旅游容量管理与调控不是剥夺或限制公民进入都市旅游和体验的权利。而是根据这种区域的极限容量阀值。疏导进入大都市的旅游流。使之保持警一种合理的、持续的容量态势发展，维系整个区域发展的可持续性。为此。要创新都市旅游容量与承载力管理的制度安排。通过都市旅游产品转型与创新、基础设施技术升级和扩能、都市旅游布局空间战略调整、区域协调与联动、实施旅游可持续指标行动等举措，进一步释放都市旅游容量及承载力潜力，缓解都市中心城区容量压力。促进都市旅游可持续发展。     

上海都市旅游与长三角区域旅游的互动响应

随着经济全球化和区域一体化进程的加速,从长江三角洲地区区域旅游发展的视角重新审视上海都市旅游发展,探析都市旅游与其周边区域旅游发展的互动响应,具有重要的先导和示范效应。基于上海都市旅游发展面临挑战及长三角区域旅游合作进程的梳理,在对长三角旅游城市体系规模结构、长三角城市旅游经济联系度等指标的测评分析与研究基础上,提出上海都市旅游与长三角区域旅游互动响应路径首先是长三角核心城市（上海 南京 杭州）网络化发展,通过旅游产业网络化、市场网络化、组织网络化、服务保障体系网络化等各个子（分）网络共同构成互补、协作和理性竞争的长三角大旅游产业体系,尝试构筑“上海都市旅游 长三角区域旅游”共轭型的旅游地域综合体,旨在推进上海都市旅游与长三角区域旅游的和谐可持续发展,进而提升长三角区域旅游的整体竞争优势。     

Comprehensive Assessment on Tourism Eco-environment of Gansu Province Based on Spatial Data

The article studies tourism eco-environment of 14 cities of Gangsu Province, China, based on GIS with many kinds of multi-subject spatial database, such as remote sensing data, observation data and literature data. The research results were as follows. First, spatial features of 14 cities＇ tourism eco-environment are displayed with five levels of vulnerability respectively. The vulnerability in Gansu becomes worse from Gannan City, located in southern Gansu to Hexi Corridor which lies in northwestern Gansu. Second, the areas of above the middle vulnerability level make up 75% of the total areas of Gansu Province. Third, more than 70% of high-level human and natural tourism resources are in the areas with high vulnerability eco-environment. Fourth, it is crucial to develop comprehensive tourism industry in order to improve the harmonious development between tourism industry and eco-environment in Gansu Province.     

中国旅游业空间集聚与集群化发展研究

旅游产业集聚与集群是联系密切而又有明显区别的一组概念,旅游产业集聚是集群形成的前提,但旅游产业集聚不一定形成集群,影响旅游产业空间集聚和集群发展的因素较多。选择行业集中度、基尼系数、赫芬代尔系数等指标,以相关数据为依据,探讨了中国旅游业的空间集聚问题,指出中国旅游业具有明显的空间集中分布与分散相结合的集聚特征。分析了中国旅游业集群发展现状与存在的问题并提出了相应对策,认为我国旅游业集群化发展是非常必要而且有可能的。     

Water Resource Management in Botswana: Balancing Sustainability and Economic Development*

Botswana is a rapidly developing country in southern Africa. Over the last three decades, diamond mining and tourism have provided double-digit rates of economic growth. Yet most of Botswana’s land is in the Kalahari desert where the climate is subject to sustained periods of severe drought. In this environment, water resources are the most crucial of all environmental resources. Water use directly affects economic development because water utilization impacts all the major national economic sectors. A sustainable water use resource management plan must stretch several decades into the future to assure the availability of adequate supplies of water to future generations while not compromising the ability of the current generation to reasonable rates of economic development. Yet thinking about sustainability is present in Botswana water policy mostly only in rhetoric. A series of cultural traditions and political constraints, coupled with bureaucratic managerial weaknesses, serve to maintain a system of water allocation that is unsustainable in the long run and inefficient in the short-term. Unless sustainable water use patterns are adopted, the results for the short-term, as well as the long-term, will be devastating. Drawing on data obtained through a series of interviews with government officials, leaders of non-governmental organizations (NGOs), and water resource researchers, this paper explores water policy in Botswana within the larger context of sustainable natural resource management practice and the pressures of economic development.
