Opportunities for Increasing Resilience and Sustainability of Urban Social–Ecological Systems: Insights from the URBES and the Cities and Biodiversity Outlook Projects
Urban futures that are more resilient and sustainable require an integrated social–ecological system approach to urban policymaking, planning, management, and governance. In this article, we introduce the Urban Biodiversity and Ecosystem Services (URBES) and the Cities and Biodiversity Outlook (CBO) Projects as new social–ecological contributions to research and practice on emerging urban resilience and ecosystem services. We provide an overview of the projects and present global urbanization trends and their effects on ecosystems and biodiversity, as a context for new knowledge generated in the URBES case-study cities, including Berlin, New York, Rotterdam, Barcelona, and Stockholm. The cities represent contrasting urbanization trends and examples of emerging science–policy linkages for improving urban landscapes for human health and well-being. In addition, we highlight 10 key messages of the global CBO assessment as a knowledge platform for urban leaders to incorporate state-of-the-art science on URBES into decision-making for sustainable and resilient urban development
Towards an\u2028 EU research and innovation policy agenda for nature-based solutions & re-naturing cities. Final report of the Horizon 2020 expert group on nature-based solutions and re-naturing cities.
1. Nature-based solutions harness the power and sophistication of nature to turn environmental, social and economic challenges into innovation opportunities. They can address a variety of societal challenges in sustainable ways, with the potential to contribute to green growth, 'future-proofing' society, fostering citizen well-being, providing business opportunities and positioning Europe as a leader in world markets. \u2028
2. Nature-based solutions are actions which are inspired by, supported by or copied from nature. They have tremendous potential to be energy and resource-efficient and resilient to change, but to be successful they must be adapted to local conditions. \u2028
3. Many nature-based solutions result in multiple co-benefits for health, the economy, society and the environment, and thus they can represent more efficient and cost-effective solutions than more traditional approaches. \u2028
4. An EU Research & Innovation (R&I) agenda on nature-based solutions will enable Europe to become a world leader both in R&I and in the growing market for nature-based solutions. For this, the evidence base for the effectiveness of nature-based solutions needs to be developed and then used to implement solutions. Both need to be done in conjunction with stakeholders. The potential for transferability and upscaling of solutions also requires further investigation. There is also a need to develop a systemic approach that combines technical, business, finance, governance, regulatory and social innovation. \u2028
5. Four principal goals have been identified that can be addressed by nature-based solutions:
�� Enhancing sustainable urbanisation through nature-based solutions can stimulate economic growth as well as improving the environment, making cities more attractive, and enhancing human well-being. \u2028
�� Restoring degraded ecosystems using nature-based solutions can improve the resilience of ecosystems, enabling them to deliver vital ecosystem services and also to meet other societal challenges. \u2028
�� Developing climate change adaptation and mitigation using nature-based solutions can provide more resilient responses and enhance the storage of carbon. \u2028
�� Improving risk management and resilience using nature-based solutions can lead to greater benefits than conventional methods and offer synergies in reducing multiple risks. \u2028
6. Based on the four goals, seven nature-based solutions for R&I actions are recommended to be taken forward by the European Commission and Member States:
�� Urban regeneration through nature-based solutions \u2028
�� Nature-based solutions for improving well-being in urban areas \u2028
�� Establishing nature-based solutions for coastal resilience \u2028
�� Multi-functional nature-based watershed management and ecosystem restoration \u2028
�� Nature-based solutions for increasing the sustainability of the use of matter and energy \u2028
�� Nature-based solutions for enhancing the insurance value of ecosystems \u2028
�� Increasing carbon sequestration through nature-based solutions \u2028This report was produced by the Horizon 2020 Expert Group on 'Nature-Based Solutions and Re- Naturing Cities', informed by the findings of an e-consultation and a stakeholder workshop. \u202
Key insights for the future of urban ecosystem services research
Understanding the dynamics of urban ecosystem services is a necessary requirement for adequate planning, management, and governance of urban green infrastructure. Through the three-year Urban Biodiversity and Ecosystem Services (URBES) research project, we conducted case study and comparative research on urban biodiversity and ecosystem services across seven cities in Europe and the United States. Reviewing > 50 peer-reviewed publications from the project, we present and discuss seven key insights that reflect cumulative findings from the project as well as the state-of-the-art knowledge in urban ecosystem services research. The insights from our review indicate that cross-sectoral, multiscale, interdisciplinary research is beginning to provide a solid scientific foundation for applying the ecosystem services framework in urban areas and land management. Our review offers a foundation for seeking novel, nature-based solutions to emerging urban challenges such as wicked environmental change issues
Biodiversity and ecosystem services science for a sustainable planet: the DIVERSITAS vision for 2012–20
DIVERSITAS, the international programme on biodiversity science, is releasing a strategic vision presenting scientific challenges for the next decade of research on biodiversity and ecosystem services: “Biodiversity and Ecosystem Services Science for a Sustainable Planet”. This new vision is a response of the biodiversity and ecosystem services scientific community to the accelerating loss of the components of biodiversity, as well as to changes in the biodiversity science-policy landscape (establishment of a Biodiversity Observing Network — GEO BON, of an Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services — IPBES, of the new Future Earth initiative; and release of the Strategic Plan for Biodiversity 2011–2020). This article presents the vision and its core scientific challenges.Fil: Larigauderie, Anne. DIVERSITAS. Muséum National d’Histoire Naturelle; FranciaFil: Prieur Richard, Anne Helene. DIVERSITAS.

Pollination by the locally endangered island flying fox (Pteropus hypomelanus) enhances fruit production of the economically important durian (Durio zibethinus)
Fruit bats provide valuable pollination services to humans through a unique coevolutionary relationship with chiropterophilous plants. However, chiropterophily in the
Old World and the pollination roles of large bats, such as flying foxes (Pteropus spp., Acerodon spp., Desmalopex spp.), are still poorly understood and require further elucidation. Efforts to protect these bats have been hampered by a lack of basic quantitative information on their role as ecosystem service providers. Here, we investigate the role of the locally endangered island flying fox Pteropus hypomelanus in the pollination
ecology of durian (Durio zibethinus), an economically important crop in Southeast Asia.On Tioman Island, Peninsular Malaysia, we deployed 19 stations of paired infrared camera and video traps across varying heights at four individual flowering trees in a durian orchard. We detected at least nine species of animal visitors, but only bats had mutualistic interactions with durian flowers. There was a clear vertical stratification in
the feeding niches of flying foxes and nectar bats, with flying foxes feeding at greater heights in the trees. Flying foxes had a positive effect on mature fruit set and therefore serve as important pollinators for durian trees. As such, semi-wild durian trees—particularly
tall ones—may be dependent on flying foxes for enhancing reproductive success. Our study is the first to quantify the role of flying foxes in durian pollination, demonstrating that these giant fruit bats may have far more important ecological, evolutionary, and economic roles than previously thought. This has important implications
and can aid efforts to promote flying fox conservation, especially in Southeast Asian countries
Natural capital informing decisions: from promise to practice
This is the accepted manuscript of a paper that will be published in PNAS. It is currently under an infinite embargo.The central challenge of the 21st century is to develop economic, social, and governance systems capable of ending poverty and achieving sustainable levels of population and consumption while securing the life-support systems underpinning current and future human well-being. Essential to meeting this challenge is the incorporation of natural capital and the ecosystem services it provides into decision-making. Here, we explore progress and crucial gaps at this frontier, reflecting upon the 10 years since the Millennium Ecosystem Assessment. We focus on three key dimensions of progress and ongoing challenges: raising awareness of the interdependence of ecosystems and human well-being; advancing the fundamental, interdisciplinary science of ecosystem services; and implementing this science in decisions to restore natural capital and use it sustainably. Awareness of human dependence on nature is at an all-time high, the science of ecosystem services is rapidly advancing, and talk of natural capital is now common from governments to corporate boardrooms. However, successful implementation is still in early stages. We explore why ecosystem service information has yet to fundamentally change decision-making and suggest a path forward that emphasizes: 1) developing solid evidence linking decisions to impacts on natural capital and ecosystem services, and then to human well-being, 2) working closely with leaders in government, business, and civil society to develop the knowledge, tools, and practices necessary to integrate natural capital and ecosystem services into everyday decision-making; and 3) reforming institutions to change policy and practices to better align private short-term goals with societal long-term goals.http://dx.doi.org/10.1073/pnas.150375111
Exploitation of TerraSAR-X Data for Land use/Land Cover Analysis Using Object-Oriented Classification Approach in the African Sahel Area, Sudan.
Recently, object-oriented classification techniques based on image segmentation approaches are being studied using high-resolution satellite images to extract various thematic information. In this study different types of land use/land cover (LULC) types were analysed by employing object-oriented classification approach to dual TerraSAR-X images (HH and HV polarisation) at African Sahel. For that purpose, multi-resolution segmentation (MRS) of the Definiens software was used for creating the image objects. Using the feature space optimisation (FSO) tool the attributes of the TerraSAR-X image were optimised in order to obtain the best separability among classes for the LULC mapping. The backscattering coefficients (BSC) for some classes were observed to be different for HH and HV polarisations. The best separation distance of the tested spectral, shape and textural features showed different variations among the discriminated LULC classes. An overall accuracy of 84 % with a kappa value 0.82 was resulted from the classification scheme, while accuracy differences among the classes were kept minimal. Finally, the results highlighted the importance of a combine use of TerraSAR-X data and object-oriented classification approaches as a useful source of information and technique for LULC analysis in the African Sahel drylands
Regenerative agriculture in Europe: A critical analysis of contributions to European Union Farm to Fork and Biodiversity Strategies
Globally, agriculture is the main driver of deforestation and land conversion, and food systems account for more than a third of global greenhouse gas (GHG) emissions, making food production a major contributor to climate change. At the same time, agriculture is extremely vulnerable to shifts and variability in temperature and rainfall, which are expected to increase because of climate change. More and more farmers, and particularly the smallholders who produce about a third of the world’s food, are struggling with harvest and livestock losses while trying to adapt to increasingly irregular weather conditions. However, the United Nations Food System Summit (UNFSS) in September 2021 pointed out that the global food system also holds important keys to keeping global warming below 2 °C. With the right investments in research, innovation and smallholder farming, UNFSS argued that it is possible to transform global food systems in ways that simultaneously reduce climate risks, hunger and poverty, and improve access to healthy diets while also enhancing biodiversity. As part of the European Green Deal, the Farm to Fork and Biodiversity Strategies together address the challenging transition of European Union (EU) agriculture towards a net 55% reduction in GHG emissions by 2030, with the aim of making European food production the global standard for sustainability. This is to be achieved by substantially strengthening diverse efforts to tackle climate change, protect the environment, and restore and preserve biodiversity in European agricultural landscapes. Here, the concept of regenerative agriculture is increasingly viewed as a promising set of principles to meet the main goals and targets of the Farm to Fork and Biodiversity Strategies. Regenerative agriculture aims to maintain agricultural productivity, increase biodiversity, and in particular restore and maintain soil biodiversity, and enhance ecosystem services including carbon capture and storage. Our evaluation of the concept of regenerative agriculture has revealed some clear advantages when it comes to developing policies for sustainable agriculture. Regenerative agriculture is not viewed as defined a priori by a given set of rules and practices; instead the goals that should be achieved are set and then practices and new technologies are adopted over time which contribute to achieve these goals. Hence the concept is viewed as broader and less prescriptive compared with other related concepts such as agroecology, organic farming, conservation farming, and carbon farming, and does not exclude the use of, for example, modern plant and animal breeding technology, tilling, use of inorganic fertilisers or pesticides, but aims for a limited, more targeted use. Although regenerative agriculture has no clear consensus definition and may have many components, there are two main characteristic features: 1. Restoration, particularly of soil health, including increasing the capacity of soils to capture and store carbon to mitigate climate change. 2. Reversal of biodiversity loss. Despite the increasing interest and application of regenerative agriculture in farming and its wide adoption by agricultural businesses, a critical scientific analysis of its effectiveness has not been conducted. This report provides a critical analysis of the main components of regenerative agriculture: soil restoration, carbon capture and storage, and reversal of biodiversity loss. On the basis of an extensive review of existing meta-analyses and systematic reviews on farming practices commonly viewed as part of regenerative agriculture (i.e. intended to increase carbon capture and storage and enhance biodiversity), the report analyses the potential synergies and trade-offs that may occur at different scales from plot- and farm- to landscape scale, and derives evidence-based policy recommendations for meeting Green Deal targets. Given the global nature of the problems regenerative agriculture is meant to address, the report analyses regenerative agriculture in the EU in its global food system context, where agriculture is viewed as a subsystem of the food system
