Review of submarine groundwater discharge (SGD) in coastal zones of the Southeast and Gulf Coast regions of the United States with management implications

Groundwater serves as the primary drinking water source for over half of the coastal populations of the Southeast and Gulf Coast regions, two of the fastest growing regions in the United States. Increased demand for this resource has exceeded sustainable yields in many areas and induced saltwater intrusion of coastal aquifers. A process associated with coastal groundwater, submarine groundwater discharge (SGD), has been documented as a source of subsurface fluids to coastal ocean environments throughout the Southeast and Gulf Coast regions and is potentially a significant contributor to nearshore water and geochemical budgets (i.e., nutrients, carbon, trace metals) in many coastal regions. The importance of groundwater as a drinking water source for coastal populations and the influences of submarine groundwater discharge to the coastal ocean warrant increased research and management of this resource. This paper highlights findings from recent SGD studies on three hydrogeologically different continental margins (Onslow Bay, NC, southern Florida, and the Louisiana margin), provides background on the common methods of assessing SGD, and suggests a regional management plan for coastal groundwater resources. Suggested strategies call for assessments of SGD in areas of potentially significant discharge, development of new monitoring networks, and the incorporation of a regional coastal groundwater resources council.     

Reconnecting to the Biosphere

Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Governance challenges include a highly interconnected and faster world, cascading social-ecological interactions and planetary boundaries that create vulnerabilities but also opportunities for social-ecological change and transformation. Tipping points and thresholds highlight the importance of understanding and managing resilience. New modes of flexible governance are emerging. A central challenge is to reconnect these efforts to the changing preconditions for societal development as active stewards of the Earth System. We suggest that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability. The ongoing mind shift in human relations with Earth and its boundaries provides exciting opportunities for societal development in collaboration with the biosphere--a global sustainability agenda for humanity.     

Remotely engaged? Towards a framework for monitoring the success of stakeholder engagement in remote regions

The importance of stakeholder engagement for the success of natural resources management processes is widely acknowledged, yet evaluation frameworks employed by administrators of environmental programmes continue to provide limited recognition of or insistence upon engagement processes. This paper presents a framework for monitoring and evaluation of engagement that aims to better incorporate community engagement into mainstream environmental programmes, in particular in remote regions such as arid and desert regions of the world. It is argued that successful monitoring of engagement should not only comprise a generic set of indicators but rather, in addition to the principles of good monitoring practice, should take into account a variety of the stakeholder interests as well as key regional drivers, addressing them at right geographic, institutional and time scale.     

The greening of Chicago: environmental leaders and organisational learning in the transition toward a sustainable metropolitan region

Urban sustainability literature calls for new governance relations to support green urban agendas. Privileging non-hierarchical relations, this literature fails to address the means by which organisations create these capacities. The author interviewed public, private and community environmental leaders in metropolitan Chicago regarding their disposition toward creating boundary spanning organisations (BSOs) in addressing the City's Environmental Action Agenda. Their responses reflect engaged efforts to enhance cross-boundary sharing of information, resources, and power. However, they also reflect the decisive role of central authority in initiating this process. These findings suggest the complexity of urban governance in transitions toward sustainability and the opportunities they provide to explore the implications of on-the-ground practice.     

Using Multi-destination ZTCM to Evaluate the Recreational Values of Cultural Sights：an Application to Jiayuguan,China

This study explained the importance of environmental protection in tourism development and illustrated the relationship between recreational resource valuation and environmental consideration. We compare different models of travel cost method and reiterates long-time existing problems of multi-destination and treats of time opportunity cost (TOC). Taking Jiayuguan's cultural sights as an example, we establish an updated method called multi-destination zonal tourism cost method to evaluate the recreational values (RVs) of selected three cultural sights. We divide trip packages of Jiayuguan's tourists into 11 portfolios. Each portfolio can be seen as a separate commodity, and each commodity has its own demand curve. According to demand curves we can calculate consumer surplus (CS) of different portfolios of tourist destinations and later we sum up the total travel costs (including travel expenditure and TOC) and CS to come to the RVs of each portfolio. We then apply suitable proportions to calculate the RVs between different destinations in the portfolio. In the end, we add up all the RVs calculated for the objective destination. Using this method, we draw conclusions that Jiayuguan's RV in 2006 includes national and international values, summing up to 738.4762 million yuan. The tourist expenditure, CS and TOC of Jiayuguan is proportionating 62.96, 32.28 and 4.76%, respectively. This study is also an example of non-market valuation of cultural tourism resources.     

Surrender or resistance to the implementation of Local Agenda 21 in Portugal: the challenges of local governance for sustainable development

The aim of this paper is to understand how Local Agenda 21 (LA21) is contributing to update local policy and decision making towards sustainable development in Portugal. Departing from a theoretical view of governance for sustainable development – its core values and challenges – and the role of LA21 in its endorsement, the paper presents the main results of a questionnaire survey submitted to Portuguese municipalities, with the purpose of understanding how far LA21 is being incorporated into planning and management. The paper then tries to expose some of the main potential, limitations and challenges in the local Portuguese case for the short-term sustainable future.

跨界大气污染治理体系和政策措施——欧洲经验及对中国的启示

大气污染具有明显的跨界特性,跨区域联防联治机制是大气污染治理的重要手段。欧洲跨界大气污染治理具有完整的治理体系和丰富的实践经验,取得了显著成就,充分借鉴和吸收欧洲跨界大气污染治理的经验,对提高中国大气污染治理的科学性和有效性、推动解决大气污染治理难题具有重要意义。本文深入分析了欧洲跨界大气污染治理的背景、制度演化、治理体系和政策措施,结果发现,欧洲跨界大气污染治理机制是以EMEP为基础、以CLRTAP为核心、八项议定书为补充的不断扩展治理领域和政策边界的动态过程,其治理政策的制定表现出明显的阶段性特征。从科学化定量体系和制度化保障体系两个维度总结了欧洲跨界大气污染治理的主要措施,结合中国实际,对中国跨界大气污染治理提出了政策建议:(1)建立健全大气治理立法及配套执行体系,并严格落实问责;(2)尽快建立和完善跨界大气污染监测评估系统;(3)科学划分大气污染治理区域,成立跨区域组织领导机构;(4)加快研究制定符合国情的跨区域生态补偿机制。     

第四次工业革命对环境治理体系建设的影响与挑战

以人工智能为代表的第四次工业革命发展迅速,特别是能源和新材料技术的突破,极大可能改变人类现有能源格局,并对建立在化石能源思维下的传统环境治理体系带来巨大影响。为此,本文梳理了第四次工业革命代表性的科技进展,分析了其对国家环境治理体系的积极影响:(1)将改变建立在化石能源基础上的工业、农业和城市形态,打破经济发展对资源、能源和土地的高度依赖,彻底告别环境污染和生态破坏;(2)将真正实现面向现在和未来的数据精准决策,显著改善人类应对不确定性环境风险能力。另一方面,由于人工智能会极大提升公民个体对复杂科学技术和社会规则的掌握能力,会改变传统治理结构中政府—市场—社会三元力量对比,给政府在环境治理领域的政策制定和执行带来新的挑战:(1)公众的能力足以使得他们对政府做出的任何不利于自己的政策提出挑战,政府信息公开和透明决策压力空前;(2)社交媒体使得公众对政府及主流媒体信息的关注大大下降,对政府如何利用新型社交媒体进行环境保护宣传教育提出了新的挑战,同时也对社会管理部门如何培育环保社会组织,弥补政府影响力下降所产生的空白提出了新的课题;(3)个体可以同时具有律师、会计、记者等处理复杂社会问题的能力,挑战政府维护社会公平稳定的利益裁量权,对环境司法公正提出更高要求。当前,中国正在进行环境体制改革创新,追求环境治理体系和治理能力现代化,如何关注、分析并积极适应由于技术变革引起的经济基础和上层建筑变化,避免制度资源错配,对于我们这样一个正在进行工业化的后发型国家尤为重要。文章最后建议,要高度关注这个领域的研究前沿进展,在制定发展规划与改革措施过程中,以未来的技术环境为出发点;要加强治理创新,引导技术朝着有利环境保护的方向发展;要加强技术对国家治理体系和治理能力双向影响研究,推进政府改革与创新,为人民提供更好的公共产品。     

Protected area governance in Sweden: new modes of governance or business as usual?

This paper explores whether ambitions to open up the traditional Swedish model of top-down conservation methods to local influences are indicative of an actual transition in governance of Swedish national park policy (NPP), and examines whether such a shift entails an increase in local influence over local interests and needs. Methodologically, we analyse a combination of governance types and incorporate theoretical definitions of power and accountability. The establishment of new governance arrangements – where power is shared, interactions promoted and accountability is directed downwards – indicates that Sweden's NPP is undergoing a change in its mode of governance. This change also seems to include ceding some influence to local interests, and the possibility of combining conservation with the utilisation of certain natural resources. The results of our research also provide valuable insights into when the establishment of shared-governance arrangements are likely to succeed; in short, this seems more likely when there are established sectors sited in a robust legal framework and where strong international commitments potentially play a role. In conclusion, we contend that when seeking diversified governance arrangements it is not enough simply to take local practices and customs into consideration – they have to be strengthened.
