我国当前城乡建设用地置换的实践探索及问题剖析

当前我国城乡建设用地利用存在着城市建设用地指标紧缺、农村建设用地低效利用和城乡建设用地"双增"大量侵占耕地等问题。城乡建设用地增减挂钩政策推动下的城乡建设用地置换有望成为破解该问题的综合途径。2004年开始,伴随相关政策陆续出台,城乡建设用地置换实践在多个省市试点推进,其中江苏省万顷良田建设工程、天津市宅基地换房、山东省农村社区化、重庆市地票交易市场的实践较为典型。基于上述典型案例和系统要素分析,总结了实践的问题、根源与演进,认为目前系统中的要素与相应的操作环节中存在问题隐患且部分问题表现突出;实践中主要以涉及"非自愿"置换、补偿与保障不足、生产生活方式改变等的农民利益受损问题较为突出;问题的根源集中在三个方面,即国家层面的约束性的法律、法规、政策尚不健全,地方政府操作不合理和缺乏科学研究支撑。今后的实践中,应该建立统一的城乡土地市场并逐步完善政府主导下的城乡土地市场运行机制,建立科学合理的征地补偿机制,深入开展相关科学研究,遵循集约型用地增长模式,同小城镇建设紧密结合,注重保护村落景观风貌。     

餐厨垃圾国家政策及地方法规研究和思考

文章介绍了餐厨垃圾的产生和危害,以及目前国家及地方在餐厨垃圾处理方面颁布和制定的指导性文件、政策性法规、及行业标准。通过总结苏州、宁波、西宁、乌鲁木齐等城市在治理餐厨垃圾过程中的经验,结合这些地区在餐厨垃圾处理方面的地方法规、收集运输系统、无害化处理体系的建立过程,通过分析思考,提出了适用于一般城市的关于餐厨垃圾收集、运输、处理过程系统性的工作框架。指出了餐厨垃圾处理目前面临的主要问题,并对未来如何推进和完善餐厨垃圾处理工作提出了合理化建议,对政府未来的决策具有一定程度的参考意义。     

低碳经济背景下地方政府环境政策执行力调控研究

环境政策执行力与低碳经济发展之间相互促进、相互推动。目前我国已形成较完整的环境政策体系,但在实际执行中并未取得应有的成效。参考国内外已有的地方政府环境政策执行力调控经验,分析环境政策执行力影响因素,从管理体制、诱导制度、监督制度、执行主体自身建设等多个角度提出在低碳经济背景下我国地方政府环境政策执行力调控策略。     

The role of coalitions in disaster policymaking

Disasters have the potential to act as focusing events, which can increase the amount of attention on disaster‐related problems and encourage policy action. Understanding of the political characteristics of disaster policymaking is underdeveloped, yet it is known that these features may be dissimilar to those of non‐disaster policy areas, especially concerning the coalitions of policy actors engaged in the disaster policy process. Coalitions in the realm of disaster policy processes may be less likely to form, may look very different, and may have different goals than those in non‐disaster domains. Knowledge of the emergence, composition, and purpose of coalitions in disaster policy is lacking. This paper draws on prior theory and case observations to define and describe the characteristics of a disaster policy subsystem and to build a typology of coalitions that may appear within such a subsystem, providing a foundation upon which scholars can work to study coalition dynamics in disaster policy subsystems.     

Return to the River: Environmental Flow Policy in the United States and Canada1

Abstract: This paper provides an overview and summary of United States and Canadian federal, state, and provincial laws that offer some form of legal protection for environmental flows. Special attention is given to the new “second generation” law established in Texas and to ways western states are beginning to encourage transactions that help restore dewatered streams. Progress in the eastern states and some Canadian provinces to provide environmental flow protection is addressed. Based on this review, this paper presents recommended elements of a “model” environmental flow policy.     

Adaptation Bridges and Barriers in Water Planning and Management: Insight from Recent Extreme Droughts in Arizona and Georgia1

Abstract: It is critical to understand the ability of water management to prepare for and respond to the likely increasing duration, frequency, and intensity of droughts brought about by climate variability and change. This article evaluates this ability, or adaptive capacity, within large urban community water systems (CWSs) in Arizona and Georgia. It analyzes interview data on the bridges and barriers to adapting water management approaches in relation to extreme droughts over the past decade. This study not only finds levers for building adaptive capacity that are unique to each state but also identifies several unifying themes that cut across both cases. The interviews also show that a particular bridge or barrier, such as state regulation, is not universally beneficial or detrimental for building adaptive capacity within each state. Such knowledge is useful for improving water and drought management and for understanding how CWSs might prepare for future climate variability and change by removing the barriers and bolstering the bridges in efforts to build adaptive capacity.     

How Research‐Prioritization Exercises Affect Conservation Policy

Abstract: Conservation scientists are concerned about the apparent lack of impact their research is having on policy. By better aligning research with policy needs, conservation science might become more relevant to policy and increase its real‐world salience in the conservation of biological diversity. Consequently, some conservation scientists have embarked on a variety of exercises to identify research questions that, if answered, would provide the evidence base with which to develop and implement effective conservation policies. I synthesized two existing approaches to conceptualizing research impacts. One widely used approach classifies the impacts of research as conceptual, instrumental, and symbolic. Conceptual impacts occur when policy makers are sensitized to new issues and change their beliefs or thinking. Instrumental impacts arise when scientific research has a direct effect on policy decisions. The use of scientific research results to support established policy positions are symbolic impacts. The second approach classifies research issues according to whether scientific knowledge is developed fully and whether the policy issue has been articulated clearly. I believe exercises to identify important research questions have objectives of increasing the clarity of policy issues while strengthening science–policy interactions. This may facilitate the transmission of scientific knowledge to policy makers and, potentially, accelerate the development and implementation of effective conservation policy. Other, similar types of exercises might also be useful. For example, identification of visionary science questions independent of current policy needs, prioritization of best practices for transferring scientific knowledge to policy makers, and identification of questions about human values and their role in political processes could all help advance real‐world conservation science. It is crucial for conservation scientists to understand the wide variety of ways in which their research can affect policy and be improved systematically.     

Downgrading,Downsizing, Degazettement,and Reclassification of Protected Areas in Brazil

Protected areas (PAs) are key elements for biodiversity conservation and ecosystem services. Brazil has the largest PA system in the world, covering approximately 220 million ha. This system expanded rapidly in the mid‐1990s to the mid‐2000s. Recent events in Brazil, however, have led to an increase in PA downgrading, downsizing, and degazettement (PADDD). Does this reflect a shift in the country's PA policy? We analyzed the occurrence, frequency, magnitude, type, spatial distribution, and causes of changes in PA boundaries and categories in Brazil. We identified 93 PADDD events from 1981 to 2012. Such events increased in frequency since 2008 and were ascribed primarily to generation and transmission of electricity in Amazonia. In Brazilian parks and reserves, 7.3 million ha were affected by PADDD events, and of these, 5.2 million ha were affected by downsizing or degazetting. Moreover, projects being considered by the Federal Congress may degazette 2.1 million ha of PA in Amazonia alone. Relaxing the protection status of existing PAs is proving to be politically easy in Brazil, and the recent increase in frequency and extension of PADDD reflects a change in governmental policy. By taking advantage of chronic deficiencies in financial and personnel resources and surveillance, disputes over land tenure, and the slowness of the Brazilian justice, government agencies have been implementing PADDD without consultation of civil society. If parks and reserves are to maintain their integrity, there will need to be investments in Brazilian PAs and a better understanding of the benefits PAs provide.
