Planning and governing nature-based solutions in river landscapes: Concepts,cases, and insights

Nature-based solutions (NBS), understood as actions that use ecosystem processes to address societal needs, can play important roles to future-proof river landscape development for people and nature. However, knowledge gaps exist how NBS can be planned and implemented at landscape scales. This Special Issue brings together insights and experiences from studies of assessing, planning, and implementing NBS in river landscapes in Europe and beyond. It addresses three research fields: (i) NBS effects, looking at the effectiveness of NBS to achieve ecological, social, and/or economic outcomes, (ii) NBS planning, focusing on approaches for planning and designing NBS, and (iii) NBS governance, relating to governance and business models for implementation. The twelve contributions deliver evidence on how NBS outperform conventional, rather technical solutions, provide guidance and tools to operationalize the NBS concept into practice, and showcase successful governance models of NBS in different contexts. The editorial ends with an outlook on further research needs.     

露天矿开采对区域生态完整性的影响研究—田家沟矿区钛磁铁矿为例

在介绍生态完整性的概念及其度量方法的基础上,以湖北省丹江口市田家沟矿区钛磁铁矿为例,从自然体系生产力、景观生态体系质量与生态系统脆弱性3个方面,阐述了露天矿开采对区域生态完整性产生的影响。结果表明：区域生物生产力的变化仅局限于项目区内;作为模地的林地优势度值从84．64％降低到80．15％,下降的幅度较小,恢复稳定性和阻抗稳定性变化也不大;各植被群落的脆弱性均属于轻微脆弱,在受到人为干扰时,森林生态系统具有稳定性和可恢复性。因此工程建设对区域生态完整性的影响在可承受的范围之内。

Caring for country through participatory art: creating a boundary object for communicating Indigenous knowledge and values

The trend towards the inclusion of diverse groups in environmental decision-making has led to the need to explore new forms of communication to engage communities in expressing their values and aspirations. Participatory art as an emergent methodology was explored with Traditional Owner groups involved in policy development through the Girringun Aboriginal Corporation in northern Queensland, Australia. The works began with a moderated focus group exploring the theme What does caring for country mean to you? Participants then worked collaboratively on one canvas over some six weeks. Individual expressions were discussed with participants during and following their creation. Themes emerging from the focus group and painting workshop included those related to culture, well-being, environment, politics, and holism, which was central to the discussions. The common thread of the work was that people need to interact with country in order to care for country.     

“Single-minded,compelling, and unique”: Visual Communications,Landscape, and the Calculated Aesthetic of Place Branding

Place branding strategies play a significant role in the professional composition of landscape imagery, including the depiction of “natural” landscapes. In this paper, Brand Blue Mountains, a brand currently implemented in the Blue Mountains region (Australia), is discursively analyzed. The brand sets out an all-encompassing “Vision” defining the identity, values and personality of the World Heritage listed Blue Mountains landscape, summarized in the tagline Elevate Your Senses. This “vision” is visually translated into a strictly coordinated and copyrighted suite of logos, graphic design, color, fonts and various photographic styles. Analysis reveals that the degree of control that place brand strategists seek to exert over the visual expression of landscape identity is significant. A highly selective narrative of positive nature-based sensory experience is constructed through the holistic application of contemporary visual media. The brands' communications strategy naturalizes and reinforces a particular market-friendly version of place. The framework that brands set for the representation of landscapes overall amounts to an exercise in calculated aesthetics, whereby the form and content of landscape images of various kinds is measured to achieve the greatest market differentiation and impact which technologies allow. The result of this calculated aesthetic system, with its taglines, saturated color, careful composition and magazine-format brevity, is a reduction in the complexity of landscape representations and a perpetuation of nature stereotypes.     

Flexibility in daily travel routines causes regional variation in bird migration speed

We used novel Global Positioning System-based satellite telemetry to reconstruct daily time budgets on travelling days of a long-distance migrant, the Osprey Pandion haliaetus, to reveal how landscape affects migratory performance. We compared daily travel routines between the Ospreys’ passage of Europe and the Sahara. In Europe, where feeding habitat is abundant, Ospreys fed both before–after flights and during interruptions, thus, combining migration with foraging. This resulted in a 2.7-h shorter daily flight period in Europe than in the Sahara. A calculated energy budget indicated that a ‘fly-and-forage migration strategy’ is favourable in Europe because associated benefits (energy intake) more than outweigh costs (reduced flight time). The much shorter flight time in Europe was the main explanation why Ospreys covered on average 78 km less distance on a travelling day in Europe than in the Sahara. In addition, there were regional differences in hourly flight speeds that are most probably the result of variation in thermal soaring conditions. We conclude that landscape properties have a profound effect on migration through regional variation in daily routines.     

社会环境道德价值观发展阶段与可持续发展

社会环境道德价值观是人们对人与自然环境道德关系的一种普遍的社会意识，它作为环境意识的核心内容，决定着人们的环境行为取向。当前我国社会环境道德价值观发展正处于从传统人类中心主义向现代人类中心主义的转变阶段。为实现我国可持续发展目标，社会环境道德价值观尚须由现代人类中心主义阶段向生存系统协调论阶段迈进。     

Measuring Asset Values and Flow Benefits of Non-Traded Products and Ecosystems Services of Forest and Woodland Resources in South Africa

Conventional measures of economic output, national income and wealth highly underestimate the value and contribution of natural resources to economic welfare. This paper makes estimates of the asset values and flow benefits of non-traded goods and services from forests and woodland resources in South Africa. Four benefit categories were included, namely direct consumptive use values (timber and non-timber products), non-consumptive use values (recreation for example), indirect use values (environmental services such as carbon sequestration, watershed protection, etc.), and non-use values (based on contingent valuation by tourists). Asset values were calculated knowing the change in physical stocks and the relevant prices. In South Africa, the increase in assets was equivalent to 1.1% of gross domestic product (GDP) (forests were improving, but fynbos deteriorating), and the flow benefits were equivalent to 0.8% of GDP. These are large magnitudes.     

Shared values for the marine environment – developing a culture of practice for marine spatial planning

Though still relatively new, the development of marine spatial planning has been based on the on the premise that as a rational planning process, it can be applied following universal principles and steps informed by land-based inspired theoretical underpinnings. However, within this process, differences between marine and terrestrial environments are being overlooked, potentially affecting the way in which the marine environment is understood and valued, and the development of a culture of practice for, and specific to, marine spatial planning. By framing planning as a cultural construct, this paper aims to explore the extent to which land-based rationales are affecting the development of a marine spatial planning culture of practice, with its own ethos and shared values. A culturalised planning model adapted from [Knieling, J. and Othengrafen, F. (2015). Planning culture—a concept to explain the evolution of planning policies and processes in Europe? European Planning Studies, 23(11), 2133–2147] is used as a framework. Whilst acknowledging the importance of the contributions from land-based planning and the ecological sciences, the findings suggest that those unconscious beliefs and perceptions affecting society’s understanding of the marine environment should contribute to informing shared values for marine spatial planning practice.
