Implementation Of Nature-based Solutions Research Articles

A framework for the successful application of nature-based solutions for climate change adaptation on rail infrastructure developed through the examination of two case studies

The management of railway infrastructure to withstand more frequent and more extreme weather conditions caused by climate change presents a significant global challenge for the rail industry. Nature-based solutions (NbS) have been proposed as potential options to protect and adapt rail infrastructure to accommodate the impacts of climate change, and an initial framework to aid the implementation of NbS in the industry has been developed. Few examples of the application of NbS in the rail environment have been documented however, with a lack of awareness on the concept being cited as the most significant barrier to its dissemination. By examining the application of NbS on two rail case studies in Adelaide, Australia, and Yorkshire, UK, including focus groups and interviews with rail professionals involved in each, this research explores the barriers encountered and the aids to NbS implementation used in these live railway examples, enabling the testing and refinement of the NbS operationalisation framework to produce an improved tool for use by the rail industry. The rail-specific case study outputs contribute to industry knowledge and awareness on NbS, which is critical for its successful uptake on rail infrastructure for climate change adaptation, and will support the continued provision of safe, sustainable rail services.

Perceptions of stakeholders on nature-based solutions in urban planning: A thematic analysis in six European cities

A commonly addressed aspect of urban planning involves the integration of nature-based solutions (NBS). Before applying NBS, acquiring stakeholders' viewpoints, e.g., city councils, local governments, and academia, contributes to the successful application and thus to mitigation of global challenges such as climate change, loss of biodiversity, water, and food scarcity. The present study explores how stakeholders across Europe view the role of NBS in urban planning. A thematic analysis was conducted to identify patterns, themes, and concepts within interview transcripts gathered through semi-structured interviews held in Budapest, Cordoba, Ljubljana, Reykjavik, Vienna, and Zurich. The study resulted in 107 distinctive codes categorized into NBS benefits, challenges, opportunities, NBS actors, and regulations. The frequency of codes (Fr) mentioned by the interviewees showed that NBS benefit cooperation (Fr=125) between individuals, while the most challenging issue obstructing NBS implementation was the lack of NBS knowledge (Fr=93). The need for green areas (Fr=42) was identified as an opportunity that could give rise to NBS applications. This study also provides practical recommendations to overcome some barriers when implementing NBS.

Can policy instruments enhance the benefits of nature-based solutions and curb green gentrification? The case of Genova, Italy

New policy solutions are necessary to make cities more liveable in a future that will be hampered by climate change, urbanization, landscape fragmentation and overall overexploitation of limited resources and space. There is an aspiration to continue to integrate Nature-Based Solutions (NBS) into global agendas to cope with climate change and urbanization due to their multiple benefits and co-benefits. Nevertheless, socio-economic and especially negative impacts of NBS are rarely considered and integrated into policy literature. Hence, the objective of this study is to address this gap by simulating three different policy instruments to mitigate green gentrification and enhance the impact of co-designed NBS in Genova. For that purpose, the spatially explicit hedonic pricing simulation model SULD (Sustainable Urbanizing Landscape Development) was used to simulate a linearly decreasing property tax to high-income households, a property tax subsidy provided to low and middle-income households and a zoning buffer policy around the NBS implementation area. Results show that all policy instruments have the ability to curb green gentrification, however the property tax subsidy led to added urban expansion, fostering urban sprawl. Both the zoning buffer and the property tax had better overall socio-economic and land use impacts by curbing green gentrification, posing little impact on low-income households and maintaining urban contraction, even though this contraction was smaller for the property tax instrument. Hence, it can be concluded that a policy mix including information, planning and economic instruments may be most effective to enhance the impact and mitigate green gentrification of NBS.

Financing climate adaptation in Flemish cities: Unpacking financial strategies and policy dynamics for nature-based solutions

As climate change continues to impact cities, nature-based solutions (NBS) are being advanced as important adaptation strategies for mitigating these negative effects. As is the case throughout Europe, Flemish cities have enacted adaptation policies and plans outlining the importance of NBS. Nevertheless, the implementation of NBS has been slow. Local governments identify financing as an important barrier. Although private financing is often proposed as a solution, few studies have applied a public-financing perspective to generate insight into and remedies for such issues. In this article, we examine how four Flemish cities are financing NBS implemented in public spaces as climate adaptation strategies. Based on a multiple case study approach, our results uncover that different financing strategies are employed during the design, implementation and maintenance phase of developing NBS projects. Additionally, we learn that the interplay between policy and financing becomes an important catalyst for investments in public NBS. We identified three approaches administrations use to secure (public) resources. During the design phase, support is developed within the administration and politically through (1) fostering internal collaboration by developing integrated spatial NBS designs. In the implementation phase resources are attracted by (2) putting the developed spatial designs to work and seizing available funding opportunities. During the maintenance phase (3) strategic partnerships are established with NBS beneficiaries to alleviate costs for municipalities. We conclude that, in the absence of more long-term forms of public financing, these approaches offer smaller cities tools to overcome the financial barrier.

Site selection for nature-based solutions for stormwater management in urban areas: An approach combining GIS and multi-criteria analysis

In recent years, particularly following the definition of the UN Sustainable Development Goals (SDGs) for 2030, Nature-Based Solutions (NBS) have gained considerable attention, capturing the interest of both the scientific community and policymakers committed to addressing urban environmental issues. However, the need for studies to guide decision-makers in identifying suitable locations for NBS implementation within urban stormwater management is evident. To address this gap, the present study employs a methodological approach grounded in multi-criteria analysis integrated with Geographic Information Systems (GIS) to identify areas with potential for NBS implementation. In this process, ten NBS were proposed and tested in the drainage area of a shallow tropical urban lake in Londrina, southern Brazil. Additionally, the study investigates areas hosting lower-income populations, a relevant aspect for public managers given the diverse economic subsidies required to implement NBS. Furthermore, the study incorporates a preliminary analysis that evaluates the potential ecosystem benefits to determine the most suitable NBS for a specific site. The result shows that all the ten analyzed NBS were deemed suitable for the study area. Rain barrels had the highest percentage coverage in the study area (37.1%), followed by tree pits (27.9%), and rain gardens (25.4%). Despite having the highest distribution in the basin area, rain barrels exhibited only moderate ecosystem benefits, prompting the prioritization of other NBS with more significant ecological advantages in the final integrated map. In summary, the methodology proposed showed to be a robust approach to selecting optimal solutions in densely populated urban areas.

A community-scale study on nature-based solutions (NBS) for stormwater management under tropical climate: The case of the Asian Institute of Technology (AIT), Thailand

Abstract Rapid urbanization and population growth are placing more demands on the world's natural water resources. New infrastructures are increasing the degree of surface sealing as well as the tendency for urban flooding and water quality degradation. These problems can be counteracted by nature-based solutions (NBS) for urban drainage in developed countries mostly having a temperate climate. Hence, there is a need to develop similar sustainable measures for tropical regions as currently there are no guidelines available. In this study, the multi-criteria decision analysis (MCDA) approach was utilized to identify the best site for NBS in the Asian Institute of Technology (AIT) in Bangkok, Thailand. Then, PCSWMM software was used to develop a numerical model. It was found that MCDA approach is an appropriate approach to determine the best site for NBS implementation considering different aspects including economic, environmental, and technical ones. The results strongly suggested that Site-1 is a suitable alternative to implement NBS in the AIT campus. It was found that a bioretention system can reduce runoff volume by at least 14% and pollutants by at least 14–20%, respectively. The present study will provide a guideline for site selection and development of the NBS model for urban water management in a tropical climate.

Key Innovations in Financing Nature-Based Solutions for Coastal Adaptation

The implementation of nature-based solutions (NBSs) for coastal adaptation to climate change is limited by a well-documented lack of finance. Scholars agree that financial innovation represents a solution to this problem, particularly due to its potential for mobilising private investments. It remains unclear however how exactly innovative solutions address the specific barriers found in NBS implementation and, given the distinctive local characteristics of NBSs, to what extent successful innovations can be replicated in other locations. This study addresses this issue by reviewing the literature and case studies of innovative financial solutions currently implemented in NBS projects, highlighting which financial barriers these arrangements address and which contextual conditions affect their applicability. We find that there is no “low-hanging fruit” in upscaling finance in NBSs through financial innovation. Innovative solutions are nevertheless expected to become more accessible with the increase in NBS project sizes, the increased availability of data on NBS performance, and the establishment of supportive policy frameworks. The flow of finance into NBS projects can be further enhanced through the external support of both public (de-risking and regulation) and private actors (financial expertise).

Microbial response to Nature-Based Solutions in urban soils: A comprehensive analysis using Biolog® EcoPlates™

The study presents a comprehensive examination of changes in soil microbial functional diversity (hereafter called microbial activity) following the implementation of Nature-Based Solutions (NBS) in urban areas. Utilizing the Biolog® EcoPlates™ technique, the study explored variations in microbial diversity in urban soil under NBSs implementation across timespan of two years.Significant differences in microbial activity were observed between control location and those with NBS implementations, with seasonal variations playing a crucial role. NBS positively impacted soil microbial activity especially at two locations: infiltration basin and wild flower meadow showing the most substantial increase after NBS implementation. The study links rainfall levels to microbial functional diversity, highlighting the influence of climatic conditions on soil microbiome. The research investigates also the utilization of different carbon sources by soil microorganisms, shedding light on the specificity of substrate utilization across seasons and locations. The results demonstrate that NBSs implementations lead to changes in substrate utilization patterns, emphasizing the positive influence of NBS on soil microbial communities. Likewise, biodiversity indices, such as Shannon-Weaver diversity (H′), Shannon Evenness Index (E), and substrate richness index (S), exhibit significant variations in response to NBS. Notably, NBS implementation positively impacted H′ and E indexes, especially in infiltration basin and wild flower meadow, underlining the benefits of NBS for enhancing microbial diversity.The obtained results demonstrated valuable insight into the dynamic interactions between NBS implementation and soil microbial activity. The findings underscore the potential of NBS to positively influence soil microbial diversity in urban environments, contributing to urban sustainability and soil health. The study emphasizes the importance of monitoring soil microbial activity to assess the effectiveness of NBS interventions and guides sustainable urban development practices.

Aligning nature-based solutions with ecosystem services in the urban century

In an increasingly urbanized world, the concepts of ecosystem services and nature-based solutions can help tackle grand challenges. However, ambiguity in their definitions and in the relationship between the two concepts complicates comprehensive research efforts as well as their effective application in policy and planning in urban systems. This paper presents a framework to clarify and explicitly relate the two concepts, enhancing their applicability in the management of urban challenges. Within the framework, addressing urban challenges serves as the starting point for the development and implementation of nature-based solutions. Nature-based solutions alter the flows of ecosystem services that are produced by an ecosystem by altering the performance of the ecosystem or by changing how people engage with the ecosystem. This results both in changes in the target ecosystem services, as well as non-targeted ecosystem services, leading to benefits. Using two illustrative case studies, we show how the framework can be applied to two urban challenges that are expected to increase in intensity in cities across the world: stormwater management and urban heat stress. Moreover, we highlight key research topics that will benefit from more integrated use of nature-based solutions and ecosystem services. The framework helps emphasize co-benefits, and can be used to help make co-benefits and multifunctionality explicit in urban decision-making and planning processes.

Nature-based Solutions can help restore degraded grasslands and increase carbon sequestration in the Tibetan Plateau

The Tibetan grassland ecosystems possess significant carbon sink potential and have room for improved carbon sequestration processes. There is a need to uncover more ambitious and coherent solutions (e.g., Nature-based Solutions) to increase carbon sequestration. Here, we investigated the rationale and urgency behind the implementation of Nature-based Solutions on sequestering carbon using literature review and meta-analysis. We also project the changes in terrestrial carbon sink of Tibetan Plateau grassland ecosystems using model simulations with different future emissions scenario. The results show that the Nature-based Solution projects are expected to increase the carbon sink of Tibetan Plateau grassland ecosystems by 15 to 21 tetragrams of carbon by 2060. We defined a conceptual framework of Nature-based Solutions that integrates initiatives for the restoration of degraded grasslands and carbon sequestration. Our framework consists of four stages: theory, identification, practice, and goal. Traditional Tibetan knowledge plays an important role in reframing the proposed Nature-based Solutions framework. We also apply this framework to optimize ecological restoration techniques and projects and to evaluate the annual changes in the carbon sink under different socioeconomic pathway scenarios.

Enhancing river floodplain management with nature‐based solutions: Overcoming barriers and harnessing enablers

AbstractFloodplains are regularly inundated areas of land that provide ecosystem benefits for the entire catchment area, along with numerous benefits for communities making them ideal for human settlement. The management of floodplains involves an ongoing dilemma; how best to balance the need to protect urban settlements from significant flood events with the benefits that inundation brings to the environmental and cultural values of the floodplain. These flood events have been traditionally addressed using technical flood protection measures. However, nature‐based solutions (NbS), provide a potential alternative approach. In this research, we analyze 29 global case studies centered on river floodplain management to investigate the barriers and enablers that affect the implementation of NbS, including floodplain restoration, mangroves, riparian forest restoration, wetland green infrastructure, among other strategies. The aim of this paper is to gain insights into improving floodplain management through the assessment of barriers and enablers evident in these case studies. The barriers and enablers were divided into six categories: social, technical, financial, political, institutional and economic and further into several sub‐divided categories. Social and technical categories were the most commonly described barriers and enablers closely followed by the institutional category. The discussion is centered around four topics: understanding community and decision‐maker risk perceptions, increased focus on stakeholders, managing multiple conflicting objectives, and consideration of multiple spatial scales. Further research on the uptake of NbS needs to focus on addressing risk communication and modeling, managing trade‐offs, and demonstration of delayed benefits.This article is categorized under: Water and Life > Conservation, Management, and Awareness Science of Water > Water and Environmental Change

Nature-based Natural-hazard Preparedness: A Cross Section of Categorized Examples

Despite prevailing interests, no rigorous research has been conducted to examine the role of nature in natural-hazard preparedness. This systematic review aimed to describe how nature can reduce the impacts of natural hazards during the preparedness stage. The study focuses on the land, water, and air systems and on three types of stakeholders: international organizations, developed countries, and developing countries. Further, it provides supplementary strategies, such as immediate actions, local engagement, and research and development, that the stakeholders should apply to enhance their nature-based natural-hazard preparedness. We suggest integrating costs and benefits analysis, local culture, societal challenges, and environmental justice into the implementation of nature-based solutions. Finally, this review outlines the framework of nature-based natural-hazard preparedness by discussing the relationship between nature and society.

Home-buying decisions influenced by the implementation of nature-based solutions: The case of Sponge City, Guiyang SW China

Urban floods induced by the compound effects of climate change and rapid urbanisation are one of the key challenges facing many Chinese cities. In 2013, China initiated the Sponge City Program (SCP) to address this issue via constructing/restoring green-blue infrastructure as Nature-Based Solutions (NBS). Various green and blue spaces have been integrated into traditional grey facilities to mitigate urban floods, provide recreational venues, and enhance the natural aesthetics of urban landscapes. While housing development has been actively included in NBS provision, it remains unclear whether and how homebuying decisions might be influenced by NBS implementation under the framework of the Sponge City Program. Our study uses Guiyang, one of the pilots selected by the central government for the construction of “Sponge City” via implementing NBS. In-depth semi-structured interviews (n = 25) were used to examine whether the multiple benefits generated by newly established green-blue (sponge) facilities would affect residents’ home-purchasing preferences/decisions. We found that the provision of a green and blue facility, and whether it is part of the SCP or not, significantly influences a homebuyers’ choice. This study sheds additional light on the nexus of end users (homebuyers) and NBS provision (developers) under the framework of the Sponge City Program, generating practical implications for stakeholder engagement for NBS implementation to achieve sustainable urbanization.

A conceptual framework to help choose appropriate blue nature-based solutions

Biodiversity loss and climate change have severely impacted ecosystems and livelihoods worldwide, compromising access to food and water, increasing disaster risk, and affecting human health globally. Nature-based Solutions (NbS) have gained interest in addressing these global societal challenges. Although much effort has been directed to NbS in urban and terrestrial environments, the implementation of NbS in marine and coastal environments (blue NbS) lags. The lack of a framework to guide decision-makers and practitioners through the initial planning stages appears to be one of the main obstacles to the slow implementation of blue NbS. To address this, we propose an integrated conceptual framework, built from expert knowledge, to inform the selection of the most appropriate blue NbS based on desired intervention objectives and social-ecological context. Our conceptual framework follows a four incremental steps structure: Step 1 aims to identify the societal challenge(s) to address; Step 2 highlights ecosystem services and the underlying biodiversity and ecological functions that could contribute to confronting the societal challenge(s); Step 3 identify the specific environmental context the intervention needs to be set within (e.g. the spatial scale the intervention will operate within, the ecosystem's vulnerability to stressors, and its ecological condition); and Step 4 provides a selection of potential blue NbS interventions that would help address the targeted societal challenge(s) considering the context defined through Step 3. Designed to maintain, enhance, recover, rehabilitate, or create ecosystem services by supporting biodiversity, the blue NbS intervention portfolio includes marine protection (i.e., fully, highly, lightly, and minimally protected areas), restorative activities (i.e., active, passive, and partial restoration; rehabilitation of ecological function and ecosystem creation), and other management measures (i.e., implementation and enforcement of regulation). Ultimately, our conceptual framework guides decision-makers toward a versatile portfolio of interventions that cater to the specific needs of each ecosystem rather than imposing a rigid, one-size-fits-all model. In the future, this framework needs to integrate socio-economic considerations more comprehensively and be kept up-to-date by including the latest scientific information.

Multi-scenario analysis in the Apulia shoreline: A multi-tiers analytical framework for the combined evaluation and management of coastal erosion and water quality risks

Ongoing climate change is causing threats to coastal areas, according to scenarios of Intergovernmental Panel on Climate Change (IPCC). The coastal areas are becoming highly exposed to erosion as a direct consequence of natural and anthropogenic processes that occur at different spatial-temporal scales. Against this interplay, coastal managers are calling for integrated tools supporting a multi-scenario evaluation of risks arising from natural and anthropogenic stress. A multi-tier analytical framework, exploiting the openly available Earth Observation databases, was developed, allowing the combination of remote sensing, GIS and Bayesian Network to evaluate the probability and uncertainty of coastal erosion risks and connected water quality variation, against ‘what-if’ scenarios, representing different management measures (i.e., Nature-Based Solution) and climate change impacts (e.g., higher incident waves due to increased storminess). Based on the available data for the Municipality of Ugento (Italy), the designed framework was applied over the 2009–2018 timeframe, allowing to capture local-scale shoreline erosion dynamics and driving forces. Results from scenario analysis revealed, to a minor extent, a nexus between oceanographic drivers, shoreline evolution, and water quality changes, with increasing probability of high erosion/accretion and higher turbidity under the simulated rising maximum significant wave height. However, the implementation of Nature-Based Solutions (i.e., circular approach exploiting beached Posidonia oceanica leaves) resulted in significant positive effects, stabilizing the shoreline by reducing high erosion and accretion rates. Despite data constraints, outcomes of the performed assessment could represent valuable information to drive adaptive policy pathways in the context of coastal management along the Ugento shoreline.

Cooperative expert-commoners action to mitigate hydraulic risk may be undermined by incomplete knowledge about nature-based solution. Results of two parallel surveys in Veneto region (Italy)

Adaptation to extreme rain events implies a reorganization of urban and peri-urban centers that involves human behavior related to the individual perception of risk. The creation and management of Nature-Based Solutions (NBS) to mitigate hydraulic risk require the collaboration of various stakeholders in the decision and management process. As in many other cooperative processes, the successful implementation of NBS necessitates the promotion of commoner confidence and cooperation. Additionally, the shared vision between commoners and technicians is expected to play a crucial role in facilitating communication and fostering synergistic action. Previous studies on hydrologic risk assessment in the Veneto Region have highlighted a general lack of awareness and acceptance of Nature-Based Solutions (NBS) among the population.This paper explores the awareness of the population regarding hydraulic risks, encompassing the risk of floods, droughts, and water pollution. It also examines the correlation between the emphasis placed by mass media and the awareness of different forms of risk in the absence of an official information campaign. Results from two parallel surveys conducted in Veneto, Italy, indicate that both commoners and technicians may have incomplete risk perception and knowledge regarding Nature-Based Solutions (NBS). Additionally, these perceptions seem to be susceptible to media influence, raising concerns about the potential for synergistic cooperation among stakeholders in the context of risk mitigation.

Nature-based solutions in agricultural landscapes for reducing tradeoffs between food production, climate change, and conservation objectives

This paper presents a synthesis of evidence and implementation gaps in the application of nature-based solutions (NbS) in agricultural landscapes that contribute to reduce trade-offs between food production, climate change and conservation objectives. The literature and data surveyed relies primarily in peer-reviewed sources and is organized around an overview of NbS science and applications in agricultural landscapes in major biomes. To date, the focus of NbS applications in food production has been predominantly for carbon sequestration, water quality, and disaster-risk management objectives while documented examples of NbS benefits in agricultural production are sparse. Conservation applications of NbS appear to show evidence of effectiveness across multiple objectives in biodiversity, land, soil and water. Evidence and analysis of NbS to meet climate change mitigation targets has surged in recent years driven by global community efforts. Overall, considerable scientific work remains to refine and reduce the uncertainty of NbS benefit estimates across production, climate and conservation objectives, and resilience implications. However, delaying implementation of NbS in agricultural landscapes would likely increase the costs to meet agricultural production, climate, conservation and other societally beneficial goals, while degrading the capacity of natural systems to continue to provide these and other ecosystem services.

Spatiotemporal monitoring of subtropical urban forests in mitigating air pollution: Policy implications for nature-based solutions

Air pollution remains a major global challenge in addressing environmental and health issues requiring continuous and immediate action. Nevertheless, the extensive adverse effects from atmospheric pollution are mainly experienced by communities and people in lower- and middle-income countries, such as the medium- and large-sized cities in Latin America including the coastal city of Guaruja in Brazil. Urban forests, as integral parts of the city landscape, play a crucial role in mitigating air pollution and should therefore be considered in environmental policies. This study aimed to evaluate the spatiotemporal concentrations of air pollutants using the biological monitoring method with Tillandsia usneoides L. to highlight the capacity of urban forests to act as nature-based solutions (NbS) in improving air quality and providing other ecosystem services. Based on the quantification of chemical indicators of vehicle emissions, scientifically recognized as traffic‐related elements (TREs) such as cadmium (Cd), Copper (Cu) and lead (Pb) in the biomonitoring samples, the results showed spatiotemporal variations in their concentrations. This finding demonstrates that urban fragments in the low-income settlement of the city exhibited higher values for TREs during the wet season. Cu values were the highest during the wet season in all study areas, underscoring the intensity of the light vehicle fleet. Forest fragments attenuated air pollution, highlighting their importance as features of environmental planning. The identification of atmospheric pollution hotspots in the territory guided the strategic implementation of NbS through tree planting, thus promoting a healthier environment with greater mitigation potential. This study is the first in Brazil to explore the spatiotemporal relationship between air pollution and urban forests in highly dense and low-income settlements providing quantitative indicators toward the benefits of NbS.

Making co-creation operational: A RECONECT seven-steps-pathway and practical guide for co-creating nature-based solutions

Co-creation as a practice of collaborative product or service development is not a novel concept, however its application in the field of nature-based solutions (NBS) requires a certain level of knowledge, expertise and capacity building to ensure a shared understanding and collaborative dialogue. NBS are defined as cost-effective and ecosystem-based solutions to solving sustainability challenges and climate-change pressures through embedding a more citizen-oriented engagement within its implementation. Although some co-creation principles and guidelines are scientifically well elaborated, only a few of them was put into practice. Thus there is still a need for making them clearer and more feasible to a broad range of stakeholders from the non-scientific community. This problem is mostly caused by the lack of easy-to use framework / strategy for organizing a co-creation and selecting the appropriate co-creation activity for the certain purpose of the NBS realization process. It includes making a right decision on what particular tools, how and with what groups of stakeholders can be applied in a certain case and by the availability of particular resources. For this purpose, a stepwise pathway/guide on how participatory approach can be incorporated into the whole process of NBS co-creation was developed within the RECONECT project. The main innovative contribution of this work is to propose the following ready-to-use solutions:•detailed seven-steps-co-creation pathway and practical recommendations for NBS design and implementation;•multidimensional and comprehensive decision-making matrix consisting of 88 tools for selecting the most suitable solution (tool) according to the particular co-creation goal, available resources and capacities;•additional resources to facilitate and operationalise the co-creation process at each stage of NBS development, offered in the form of a Toolbox.

A global assessment of lake restoration in practice: New insights and future perspectives

A global survey of 179 restoration practitioners spanning 65 countries identified the extent of stakeholder engagement as a key factor determining the success or failure of restoration projects. Lack of support across sectors and for funding, policy, monitoring, governance and knowledge assessment of pressures and their effects were most frequently cited as factors contributing to restoration failure.The responses indicate that, although nutrient enrichment is perceived to be the primary issue for lakes globally, the impacts of climate change, hydrological modifications and invasive species are widely recognized as pervasive anthropogenic pressures of global importance. Practitioners recognized that the ecosystem services most impacted by these pressures were recreation and tourism, although in low income countries the provisioning service, aquaculture, was considered most impacted. Ecology-based and/or pressure-related restoration targets had been set for most restoration programs in our survey. However, the strength of the evidence underpinning these targets was often weak and the effects of climate change were rarely considered when setting targets.The most effective and widely used restoration measures target nutrient loading (both catchment and in-lake) while hydrological modifications and the implementation of nature-based solutions are used to a lesser extent. Measures for the control of non-native invasive species are rarely applied and are viewed as being largely ineffective.The results of the survey provide direction for future work. New and emerging pressures, singly and in combination, may require new approaches to lake restoration: for both setting restoration targets and devising restoration strategies. The future of lake restoration depends on joined-up thinking that better integrates science into policy and practice and, most importantly, ensures strong and inclusive stakeholder engagement and collaboration across multiple sectors.
