地方依恋有助于提高农户村庄环境治理参与意愿吗?——基于湖北省调查数据的分析

在农村社会转型背景下,从人地关系视角探讨农户地方依恋对其村庄环境治理参与意愿的影响,对剖析农村环境治理难题意义重大。以湖北省为例,利用1074份农户微观调查数据,从环境心理学视角下的人地关系出发,探讨了地方依恋对农户村庄环境治理参与意愿的影响,并进一步运用工具变量法(IV-Oprobit)进行内生性处理与稳健性检验。结果表明:①农户地方依恋水平整体一般,通过提高农户对村庄的依恋水平,可显著提升其村庄环境治理参与意愿。具体而言,农户地方依恋水平每提高1个单位,可使其环境治理“非常愿意”参与的概率提升35.51%。②社会信任在地方依恋对农户村庄环境治理参与意愿影响中发挥显著的调节和中介作用。一方面,地方依恋对农户村庄环境治理参与意愿的影响会随着农户社会信任水平的提高而不断增强;另一方面,地方依恋能够显著增强农户社会信任水平,从而提升其村庄环境治理参与意愿,即社会信任是地方依恋影响农户村庄环境治理参与意愿的重要传导中介,中介效应占总效应的比重为23.37%。③代际差异分析表明,在新生代和老一代农民群体中,地方依恋对其村庄环境治理参与意愿影响均显著。此外,性别、环保意识和环保态度等对农户村庄环境治理参与意愿也产生显著影响。据此,应加强村庄基础设施和文化建设等,不断增强农户的村庄认同感和依恋感,进而在美丽乡村建设中提升农户村庄环境治理参与水平。     

Leverage points to foster human–nature connectedness in cultural landscapes

Calls for a reconnection to nature and the biosphere have been growing louder over the last decades. Cultural landscapes are rapidly changing, posing a threat to ecosystems and biodiversity, but also to human–nature connections. Human–nature connectedness may be a potential lever to shift the unsustainable trajectory that we are currently proceeding, but is also negatively influenced by it. To concretize the call for a reconnection to nature, we used the leverage points perspective on five empirical case studies with focus on human–nature connectedness. Based on the synthesis of our yearlong work, in this perspective paper, we propose four leverage points to foster a sustainability transformation: (1) maintain and enhance the structural diversity of landscapes, (2) maintain and enhance economically and ecologically sustainable small-scale agriculture, (3) strengthen sense of place and (4) strengthen sense of agency in actors. Intervening in these leverage points could be effective to foster human–nature connectedness and ultimately contribute towards a sustainable trajectory. We further argue that the interconnection between leverage points is equally important as their systemic depth.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01504-2.     

Access and Local Government Research: Methodological Reflections

Abstract

This methodological paper draws on research from Australia to examine the question of gaining access to local governments in undertaking work on natural resource management. It is argued that a range of macro-level changes have impacted on the local government sector in Australia, and these changes have rendered access problematic for researchers. These changes include an expansion of local government roles, an increase in financial pressure within the sector, a proliferation of audit measures across local governments and a low level of respect amongst local government personnel for academics and academic work. The paper concludes by identifying the reasons why understanding access in qualitative research on local government and environmental sustainability is important.     

Reducing carbon,tackling fuel poverty: adoption and performance of air-source heat pumps in East Yorkshire,UK

Deploying heating technologies, such as air-source heat pumps (ASHPs), can respond to the dual challenges of tackling fuel poverty and reducing carbon emissions from domestic energy consumption. In the UK, ASHP performance has been found to be below design levels. Elements of three strands of literature – innovation diffusion, environmental psychology and neighbourhood effects – are combined to gain insights into why the adoption and performance of ASHPs are lagging policy targets and design potential. Evidence from users, installers and area-based scheme facilitators suggests that the perceived complexity of the technology is a barrier. The level of technology maturity and the typical profile of the elderly fuel poor do not match; the target group might prefer to be late adopters or laggards in adopting technology. The role of installers is critical as the disruption from installation is a barrier to adoption and ASHPs place demands on users to change existing practices.     

高密度电阻率法在排石场稳定性评价中的应用

简述了高密度电阻率法的工作原理。在将高密度电阻率法实际应用于排石场的稳定性评价中时,根据各种装置的特点和T、λ参数对高低电阻率的表征特性,进行了多装置及多参数的探测。通过对各二维反演视电阻率成果图的综合对比和解释,划分出了存在地质隐患的区段。经钻孔验证,效果很好。结果表明通过高密度电阻率法多装置、多参数勘探,可以确定地下介质的电阻率及其电阻率特征,进而对排石场的稳定性做出评价,对同类地质情况的监测、预警,也是行之有效的。     

背景噪声的测量和用于修正计算的问题分析及建议

在诸多有关噪声排放的标准中，背景噪声的定义在时间和空间位置方面的规定不够完备；相关的测量的规范方法也未对背景噪声的测量作了规定。实际操作上的“非同时性”给背景噪声的测量结果及用于修正均带来一些失准问题。文中分析了这些问题并提出了初步建议。     

城市体育馆应急避难服务能力评价研究

为了更好地提升体育馆在灾时的应急效率及服务能力,对城市体育馆的应急避难服务能力进行评价,并基于系统管理视角从工作人员素质、设备设施配置、支撑结构功能、应急响应能力4个方面建立包含19个特定指标的城市体育馆应急避难服务能力评价体系。对北京市中心城区4座区级体育馆进行实地调研,凭借建立的指标体系利用FAHP法进行避难服务能力评价,发现4座体育馆整体水平均处于合格水平以上,但通过对比总结分析发现,4座体育馆在志愿者队伍建设、应急标识系统、应急避难响应能力3个指标上存在共性问题,研究结果可为今后改善体育馆避难能力提供借鉴意义。     

Assessment of predation risk via illumination level: facultative central place foraging in the cricetid rodent Phyllotis darwini

It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess predation hazard since direct evaluation may be dangerous. I studied the assessment of predation risk, manipulated via environmental illumination level, and the trade-off between foraging and predation hazard avoidance in the nocturnal rodentPhyllotis darwini (Rodentia: Cricetidae). In experimental arenas I simulated dark and full moon nights (which in nature correlate with low and high predation risk, respectively) and measured the immediate responses of animals to flyovers of a raptor model. Second, varying illumination only, I evaluated patch use, food consumption, central place foraging, and nocturnal variation of body weight. During flyover experiments, animals showed significantly more evasive reactions under full moon illumination than in moonless conditions. In the patch use experiments, rodents significantly increased their giving-up density and decreased their total food consumption under moonlight. On dark nights, rodents normally fed in the food patch, but when illumination was high they became central place foragers in large proportion. Moreover, the body weight of individuals decreased proportionately more during bright nights. These results strongly suggest thatP. darwini uses the level of environmental illumination as a cue to the risk of being preyed upon and may sacrifice part of its energy return to avoid risky situations.     

Biofuels – tools for achieving environmental goals or green place branding? Present drivers and future visions in two Swedish municipalities

This paper presents a study of two Swedish municipalities’ engagement in biogas development. To analyse the drivers of such biogas development, the conceptual framing incorporates two perspectives on local biogas policy: first, policy drivers as connected to environmental goals and, second, policy as a matter of green place branding. The results indicate that biogas engagement serves as a self-governing activity with the fulfilment of environmental goals as a driver; furthermore, it is a way of expressing the mission of municipalities as “engines” of environmental policy. In one studied municipality, biogas engagement has an important symbolic value for green identity, meaning that green place branding is a driver. Still, interviewed actors from both municipalities lack clear long-term visions of biogas. Further studies of biofuel production should critically investigate visions of the future among central and local governments and evaluate the implications of municipalities as biofuel producers.
