Water Management Decision Making in the Face of Multiple Forms of Uncertainty and Risk

In the Wasatch Range Metropolitan Area of Northern Utah, water management decision makers confront multiple forms of uncertainty and risk. Adapting to these uncertainties and risks is critical for maintaining the long‐term sustainability of the region's water supply. This study draws on interview data to assess the major challenges climatic and social changes pose to Utah's water future, as well as potential solutions. The study identifies the water management adaptation decision‐making space shaped by the interacting institutional, social, economic, political, and biophysical processes that enable and constrain sustainable water management. The study finds water managers and other water actors see challenges related to reallocating water, including equitable water transfers and stakeholder cooperation, addressing population growth, and locating additional water supplies, as more problematic than the challenges posed by climate change. Furthermore, there is significant disagreement between water actors over how to best adapt to both climatic and social changes. This study concludes with a discussion of the path dependencies that present challenges to adaptive water management decision making, as well as opportunities for the pursuit of a new water management paradigm based on soft‐path solutions. Such knowledge is useful for understanding the institutional and social adaptations needed for water management to successfully address future uncertainties and risks.     

国家重点生态功能区县域环境监测质量评价方法及应用示范

以国家重点生态功能区县域环境监测质量评价为目标,综合应用德尔菲法、层次分析法和模糊综合评价法,构建了国家重点生态功能区县域环境监测质量评价方法,并确定了评价因子、权重系数、计算方法。该方法评价指标共分为三层:第一层为目标层,即国家重点生态功能区县域环境监测质量;第二层为准则层,包括人员及资质、现场监测、实验室管理、报告编制及数据上报;第三层为方案层,包括人员操作、持证上岗、资质认定、人员培训、水质布点采样流转情况、空气自动站运维情况、现场质控实施情况、实验室环境条件、样品试剂的保存与管理、仪器检定与校准、实验室质量控制实施情况、数据填报软件运行情况、监测报告规范性等13个评价要素。经矩阵一致性检验确定了各评价要素的权重,将该权重与各要素得分运算后得到县域环境监测质量评价结果。在此基础上,选取广东、山西、陕西、四川和青海等5个省份的15个国家重点生态功能区县域作为典型区开展了实地调研,并应用评价体系对其进行了监测质量等级评价。结果表明,15个典型县域中,环境监测质量等级为优的县域占13.3%,一般、较差的县域分别占66.7%、20%。县域环境监测承担单位在资质、报告编制及数据上报方面表现较好,在现场监测、人员操作方面问题突出,在实验室管理方面有待提升。

地方政府土地出让策略互动行为的检验及其影响分析

本文以山东省设区市地方政府土地出让行为作为研究对象,通过构建空间面板模型,从价格和数量两个维度,全面检验了地方政府商服、住宅、工业用地出让的策略互动行为,并利用空间计量工具,分析了地方政府土地出让策略互动行为的影响。研究发现:(1)山东省内地方政府商服、住宅、工业用地出让价格以及工业用地出让量存在显著的策略互动,地方政府的商服、住宅、工业用地出让价格以及工业用地出让量,不仅会受城市自身情况的约束,还会受邻近地区地方政府土地出让行为的影响,外在表现为你涨我跌、你增我减的反向变动格局;(2)由于未考虑策略互动,传统计量经济学非空间面板模型对地方政府土地出让行为影响因素的估计普遍存在偏误。对于商服用地出让价格,第三产业比重、人口密度的影响分别被低估了33.33%、13.08%;对于住宅用地出让价格,人口城镇化率、人均可支配收入的影响分别被低估了20.00%、9.98%,人口密度的影响被高估了32.34%;对于工业用地出让价格,人均外商直接投资的影响被高估了3.68%;对于工业用地出让量,第二产业比重、地均工业产值的影响分别被高估了13.95%、31.36%;(3)地方政府土地出让行为的影响因素普遍存在明显的空间溢出效应。对于商服用地出让价格,具有空间溢出效应的影响因素为人口密度;对于住宅用地出让价格,具有空间溢出效应的影响因素为人口城镇化率、人口密度、人均可支配收入;对于工业用地出让价格,具有空间溢出效应的影响因素为人均外商直接投资、地均固定资产投资;对于工业用地出让量,具有空间溢出效应的影响因素为第二产业比重、地均固定资产投资。     

The 2030 Agenda for Sustainable Development and China’s implementation

The concept of sustainable development has experienced great development and change at different levels of theoretical connotation and practical implementation since 1960s and 1970s when it was first proposed. People’s understanding of the relationship between economy, society, and environment has been continuously deepened over the years. When it came to the end of 2015, it is necessary to examine the results of the United Nations Millennium Development Goals on sustainable development, and at the same time, the post-2015 framework and guidance on sustainable development at the global level were to be made, including the ideas, action plans, key areas that would guide the global sustainable development. The 2030 Agenda for Sustainable Development has developed a 5P theoretical framework of being people-centered, global environmental security, sustained economic prosperity, social justice and harmony and partnership promotion, including a political declaration, 17 overarching goals and 169 specific targets, specific ways of implementation, as well as the follow-up. It is the road map to achieve global sustainable development and meet the requirements of the millennium development goals. This paper summarizes the understanding of the concept of sustainable development from its origin, its significant development, to the proposition and development of the 2030 Agenda for Sustainable Development, and its strategic impact on China.     

Application of environmental risk assessment for strategic decision-making in coastal areas: case studies in China

Environmental risk assessment (ERA) is a powerful technical tool for analyzing potential and extreme adverse environmental impacts, and has found wide application in supporting decision-making processes over the last two decades. However, to date there has been no interrelated application of ERA to support the processes of strategic decision-making (SDM), especially in coastal areas.

In this paper, we attempt to verify the feasibility of the proposed integrated ERA–SDM approach and its methodology by applying it to two case studies (in Xiamen Bay and Luoyuan Bay) of the principal coastal functional zoning (PCFZ, a kind of SDM and similar to the coastal and marine spatial planning in western). The results show that the integrated ERA–SDM approach could integrate ERA into the entire SDM process, directly support the PCFZ, and avoid or mitigate dire environmental risk that can be introduced by SDM processes.     

Applications of Very High‐Resolution Imagery in the Study and Conservation of Large Predators in the Southern Ocean

The Southern Ocean is one of the most rapidly changing ecosystems on the planet due to the effects of climate change and commercial fishing for ecologically important krill and fish. Because sea ice loss is expected to be accompanied by declines in krill and fish predators, decoupling the effects of climate and anthropogenic changes on these predator populations is crucial for ecosystem‐based management of the Southern Ocean. We reviewed research published from 2007 to 2014 that incorporated very high‐resolution satellite imagery to assess distribution, abundance, and effects of climate and other anthropogenic changes on populations of predators in polar regions. Very high‐resolution imagery has been used to study 7 species of polar animals in 13 papers, many of which provide methods through which further research can be conducted. Use of very high‐resolution imagery in the Southern Ocean can provide a broader understanding of climate and anthropogenic forces on populations and inform management and conservation recommendations. We recommend that conservation biologists continue to integrate high‐resolution remote sensing into broad‐scale biodiversity and population studies in remote areas, where it can provide much needed detail.

The Quagga Mussel Crisis at Lake Mead National Recreation Area,Nevada (U.S.A.)

Abstract: Parks are cornerstones of conservation; and non‐native invasive species drive extensive changes to biological diversity in parks. Knowing this, national park staff at Lake Mead National Recreation Area in the southwestern United States had a program in place for early detection of the non‐native, invasive quagga mussel (Dreissena rostriformis bugensis). Upon finding the mussel in January 2007, managers moved quickly to access funding and the best available science to implement a response. Managers considered four options—doing nothing, closing the park, restricting movement on the lakes, and educating and enforcing park visitors—and decided to focus on education and enforcing existing laws. Nonetheless, quagga spread throughout the park and soon began to appear throughout the western United States. I examined why efforts to control the expansion failed and determined the general lessons to be learned from this case. Concentrating human visitation on the lakes through land‐use zoning opened a pathway for invasion, reduced management options, and led to the rapid spread of quagga. To reconcile competing mandates to protect nature and provide recreation, zoning in parks has become a common practice worldwide. It reduces stress on some areas of a park by restricting and thus concentrating human activity in particular areas. Concentrating the human activity in one area does three things: cements pathways that repeatedly import and export vectors of non‐native invasive species; creates the disturbed area necessary to enable non‐native invasive species to gain a foothold; and, establishes a source of invasions that, without appropriate controls, can quickly spread to a park's wilderness areas.
