Traversing waters : Recognizing Wetland Ecosystems Value in the Lower Danube

Persina Nature Park has high conservation value but is also of importance to local economies through its fish resources, climate regulation and biomass production. However, the societal, economic and environmental value of this wetland is not well recognized by local and national stakeholders and decision-makers. This exemplar aims to explore the link between Danube ecosystems and a range of environmental benefits for local and Danube-region communities, given the application of an appropriate set of instruments to safeguard or improve them.

Exploring how ecosystem services can be integrated in a land-use planning process using a real-life planning case. A special focus is on multifunctional green infrastructure and applying new tools to operationalise ecosystem services in the plans in a participatory way.

Informing policy makers at national and EU level about the short and long term consequences of forest bioenergy production and its trade-offs for other ecosystem services.

Quantifying the links between the ecological status and the provision of ecosystem services for a freshwater lake. Focus is on understanding environmental quality needed to deliver recreation and fishing services provided by the lake, and the value of these two services.

Testing the feasibility of a green infrastructure, instead of a traditional grey infrastructure, to treat sewage overflows, and investigating the multiple benefits that the green infrastructure provides and its relevance for water management.

There were plans for a huge dam for hydro-electric energy production, mainly for export. The study was designed as a standard Cost-Benefit Analysis (CBA), including environmental costs and distributional impacts. Cost-benefit-analysis was used to assess the value of the project because it is a widely accepted framework and can combine diverse secondary data about the expected consequences. Despite time pressure and relatively poor data availability, conservative estimates about investment costs, likely returns and environmental damage (along with associated loss of natural assets and...

Removing sediment from reservoirs is an important part of the costs of hydro-power generation. Under the “Rewarding Upland Poor for Environmental Services” project (RUPES), an initiative by ICRAF, upstream farmers changed land-use practices for reducing soil erosion and sedimentation load in streams. The sedimentation rate was used as an indicator to measure the effectiveness of the agreed activities. Monitoring sedimentation rate as an indicator for the positive impact of improving land-use practices made the success of the changes in land-use practices transparent and motivated all...

Removing sediment from reservoirs is an important part of the costs of hydro-power generation. Farmers adapt and diversify land-use, based on PES scheme with hydro-power company in Sumberjaya.

Protecting mangroves for local benefits, Philippines

Despite legal protection, mangroves were being cleared for shrimp farming by non-local investors. In a multi-day workshop, the ideas was to learn from local community stakeholders and participating scientists about the problems surrounding the conversion of mangrove ecosystems to shrimp aquaculture.

The aim was to develop potential solutions to the problems and communicate results to the authorities to take action. The main questions to be answered were: How to compare the value attached to shrimp farming with the value of maintaining mangroves? How can the economic, social and...

This case illustrates how ecosystem service assessments can help to catalyse changes in conservation and development policy and management practice − but are rarely the sole factor. In the Upper Tuul example, the intention was to “make the case” for a higher policy and budgetary priority to be accorded to the UpperTuul ecosystem.

The central Uzbek government needed to be convinced that investments in the Amu Darya delta would make social, ecological and economic sense. Ecosystem services of the delta were valued for three situations: the situation before degradation, the present degraded and the potential restored situation.

The Project “Demonstrating and promoting natural values, to support the decision-making process in Romania” (N4D) was developed based on folowing activities: A1. institutional infrastructure development; A2. Development of the ecosystem mapping and assessment framework in Romania; A3. Data analysis and management under the MAES process; A4. Biophysical mapping and assessment of ecosystems and of their services; A5. Project promotion; A6. Knowledge exchange with the neighbouring countries and with Norway, as the country providing the Project financing.

The Park 500 Natural Treatment System (NTS) was constructed as a voluntary effort to provide a low-energy, low-maintenance alternative to reducing nitrogen and phosphorus in the process’s wastewater, which is high in nitrate-nitrogen, organic nitrogen and total phosphorus.

The project was initiated to reduce the environmental footprint of the tobacco production facility and help Philip Morris USA meet its environmental sustainability goals. The NTS reduces mass loading to the James River and creates a performance buffer for the existing plant discharge to ensure long-term...

Current catchment provision of flood mitigation services

Minimising the impacts of dredging and flood bank extension: In 2018/2019, in the Ria de Aveiro two management interventions will have negative unintended impacts on biodiversity: 1) a dredging programme to manage water flow and navigability in Ria de Aveiro coastal lagoon, and 2) the extension of a flood bank to stop surface saltwater intruding onto local farmland. The goal of this study is to apply adaptive management and minimise foreseen but unintended management challenges in a Natura 2000 protected area, which crosses fresh and marine waters, in the context of EU...

Rönne å catchment area is a river watershed located in Southern Sweden and includes lakes (e.g. Ringsjön), rivers (Rönne å) and marine coastal areas (Kattegatt). The AQUACROSS Case Study looks at the process of eutrophication and restoration of good water quality and their implications for the provision of ecosystem services along the Rönne å catchment.

Revitalisation in Chriesbach © Eawag, Peter Penicka

Freshwater ecosystems in the Swiss plateau are threatened by multiple stressors that deteriorate water quality and hydromorphology. This is the result of channelization, dams, wastewater, and agriculture, among other causes. To restore these ecosystems and stop the biodiversity decline, multiple management measures will be implemented over the next decades. We propose methods for prioritising the location and timing of restoration measures to maximise their effectiveness, considering many sectors and multiple societal objectives.

The objective of the LIFE-EnviFriendly project was to demonstrate low cost, nature based solutions that if used by all farmers within a watershed it will improve the water quality of the waters significantly. The NBS used in this case was a riparian forest restoration coupled with a river bank erosion protection.

The public perception of ecosystems (e.g. forests, including possibly protecting ones) is strongly worsened following floods with massive wood jams. This case study aims at performing a comprehensive and in-depth analysis of a Mediterranean catchment to assess NBS benefits, dis-benefits and co-benefits and ways to optimize them.

The aim of this research was to understand how private sector natural capital investments could be increased and diversified in the Spey catchment. The focus of the study was on businesses that do not primarily manage land, but nevertheless rely on the Spey landscape, e.g. for their supply chain or to attract customers. Specifically, the study tried to answer four questions:
1. How do businesses currently invest in natural capital?
2. What motivates and hinders businesses to invest in natural capital?
3. Is there potential for coordinated business investment in natural...

In its 2016-2022 Development Plan the city has set out a vision for a ‘Sustainable, Resilient Dublin based on economy, environment and equity’ (1). The Development Plan’s principles for green infrastructure include sustainable buildings which should use ‘sustainable energy technologies and innovative design solutions such as living walls, roofs as well as solar panels’. NBS could help address climate change, environmental infrastructure, green infrastructure, open spaces and recreation, cultural heritage and sustainable communities and neighbourhoods (1). For example, sustainable urban...

The city is currently revising its urban Master Plan, which aims to make Bilbao i) an example for other cities around the world; ii) a city in continuous renewal; iii) a sustainable city; and iv) a socially balanced city.

Extreme climate events in the recent – and not-so recent – past have shown that Bilbao is more vulnerable than most other cities. This realisation prompted scientific research into how the city could plan for sustainable development and prepare itself for further climate-change risks.

This resulted in the city authorities drawing up a list of the following...

All of the challenges identified in the Bristol Development Framework Core Strategy (1) concern areas which would benefit from NBS. Furthermore, the 20:20 plan – Bristol’s Sustainable City Strategy (2) – has identified climate change as one of three key challenges. It acknowledges the potential for green infrastructure, such as trees, green walls and roofs, to minimise and mitigate the urban heat island effect, while Sustainable Urban Drainage Systems (SUDS) are seen as an important part of flood management. Bristol’s Parks and Green Spaces Strategy (3) includes a 20-year investment...

To address these challenges, Budapest has drafted several strategic documents, in which NBS are promoted as a way to improve the environment, sustainability, and quality of life. These documents include:

The Budapest 2030 Long-Term Urban Development Concept. This strategic document aims to protect and increase green areas, so as to ensure ecological connectivity and develop walking and cycling corridors. It also promotes greater investment in brownfield sites, the prevention of urban sprawl, and 'smart' city development.
The Integrated Urban Development Strategy 2020.

Urban redevelopment was an opportunity to adopt solutions and achieve different targets through nature-based solutions. Carta of Milan, the city's strategic environmental plan, recognises ‘green infrastructure’ as the best way to achieve environmental targets, promote social development and improve social welfare. On a wider scale, the Lombardy Region manages the green infrastructure actions for ecological connections and the creation of ecosystems, ensuring continuity between the Alps and the Po Valley (Pianura Padana) and the urban environments within that area...

The above-mentioned challenges are addressed in Oradea’s plan for a green area within a 5 minute walking distance from anywhere in the city, evaluated in its Urban Development Plan 2030. Oradea’s main objective is to improve quality of life for its citizens, including by prioritising the increase of leisure opportunities.

Szeged’s urban development concept and integrated urban development strategy aim to improve the quality of green areas and to restore natural habitats and ecological corridors for social and recreational purposes and to mitigate the impacts of climate change. Due to the required structure for integrated urban development strategies and related financing mechanisms, there are separate objectives and plans for most urban districts (Liget, Mórapark, Makkosháza, Odessza, Roosevelt square, Tápé, Tarján, Stefánia, Vértó). They are called action areas and are developed in relation to the general...

The city’s Grünlandkonzept (green space strategy) provides detailed strategic indications for local land use and infrastructure planning (Stadt Linz, 2013). Enhancing and protecting urban green areas is seen as a way of increasing the city’s attractiveness, and will also form part of the upcoming transformation of the city harbour area. Linz AG, a holding company owned by the municipality, is planning to position the harbour on the Danube river as an important regional and international business location, inter alia by means of intensive greening for parts of the area...

The primary goal of the city strategy (Development Strategy for the City of Poznań 2030) is to improve quality of life for all inhabitants, in such a way that everyone feels that they have a stake in co-creating the city. One of the five strategic objectives of the city strategy – 'A green, mobile city' – sets out NBS objectives, while the other strategic objectives, including 'Friendly housing estates' and 'The spirit of community and social dialogue' contain elements of NBS. NBS objectives are also incorporated in the documents on strategy and additional spatial planning (Development...

Genk’s multi-annual strategic plan for 2014-19 is a response to the closure of the Ford car manufacturing company. The main objective of the plan has been to use Genk’s natural and human capital for sustainable value creation. Nature-based solutions are an integral part of the plan, used to create blue-green connections (top-down approach) and promote social inclusion (bottom-up approach).

The Greater London Authority (GLA) participants in the BRIDGE FP7 project identified the primary planning goals for the Central Activities Zone (CAZ)[1] as to: (a) increase green space; (b) improve air quality; (c) reduce the UHI effect (heat island) and (d) prevent flash floods, with climate change adaptation and mitigation seen as a cross cutting issue.

London has a number of plans aimed at addressing these challenges, including:

The Mayor’s London Plan in which two goals relate to urban green space and aim

In the framework of "Vision Ljubljana 2025", the city has adopted several sustainability-oriented strategic documents, especially the:

Urban Master Plan (83% of all city development is directed towards renewing existing developed areas and brownfields). This is the most important planning instrument for green spaces in the city.

Environment Protection Programme 2014-20, aiming to protect and enhance the natural environment in the city.

To improve and validate a portable, modular, enery-free, decentralized water treatment system, the PM-NBSTM, to remediate source water to high quality for resuse, filling a major gap in small agglomerations and remote areas where good quality waters are needed and no other solution is feasible

Together we can build more resilient and liveable cities

The overall objective of BEGIN is to demonstrate at target sites how cities can improve climate resilience with Blue-Green Infrastructure involving stakeholders in a value-based decision- making process to overcome its current implementation barriers.

BEGIN’s driving ambition is to substitute traditional ‘grey infrastructure’ such as concrete for ‘blue-green infrastructure’ (BGI) such as parks, rivers, and lakes.

The aim was to deliver sustainable drainage systems (SuDS) measures on school sites in order to reduce local flood risk, provide benefits for participating schools and educate the pupils and wider community about surface water flooding .

The Programme for Enhancing the Urban Green Infrastructure is an ambitious government measure approved in 2017. It establishes the main strategies for enhancing the quality and quantity of green infrastructure in Barcelona till 2030. Barcelona wants to renature the city and create, in this period, 165 ha of new green spaces, which increases the green spaces/inhabitant ratio by 1m². As Barcelona is a compact city, there are various strategies to improve, transform or create new green spaces. The actions will take place at various urban scales (street, district or city scale) and...

UAG parks were installed since 2011 as part of a process of social inclusion, where quality of the public space was the decisive point for citizen engagement and approval.

For several reasons, protecting important ecological areas in Lisbon from urbanisation has become difficult. Remnant areas of natural habitat have gained particular importance in consolidating the green corridors network, benefiting from the fact that much of this land is still within the municipality’s property holdings. The “Lisbon Green Plan” published in 1996 set out the approach used in 2008 to implement safeguarding measures to protect the ecological structure under development threat at that point. It triggered an update to the Lisbon Master Plan at a time when climate issues were...

A Green Infrastructure Plan of Llanquihue, which includes the Baquedano Wetland Park, was developed through the joint working of the Landscape Architecture Master Program Universidad de Chile and the NGO Legado Chile Fundatio. It is a response to several socio-ecological pressures created by urban living that were affecting ecosystems within the city boundaries. In 2016 both institutions called on an open dialogue with 300 members of the community, including residences, local authorities, the school community, regional services, representative of productive industries, scientists and...

The so-colled Border Meuse or "Grensmaas" Project has three main objectives: reduce flood risk, healthier and more diverse nature, and the commercial benefit of both gravel extraction and nature-based economic development.

The extensive use of bromelias on the green roofs for keeping the weight of the structure low for safety (Image from Herzong and Rozado 2019).

Controlling and mitigating the heat island effect in Arará slum, northern Rio de Janeiro, based on the development and monitoring of green roofs, using epiphytes or lithophytes. Given the common uses of cement or metal, tiles required the development of specific techniques and materials to allow for the growth of vegetation while keeping the overall weight low for safety.

This case study examines in particular the interface between four sets of plans and strategies, providing important context for further examination of meso- and micro-scale interventions covered in subsequent sections. This case also touches on other formally adopted plans and strategies only in relation to the above meso- and micro- scale initiatives, in an attempt to better understand contexts.

Example of a forest restoration planned and conducted by activists and local engaged population in the city of São Paulo (image courtesy by Ricardo Cardim).

Developing a planting scheme with the support of the local engaged population. The creation of national institutions and laws that gave the support for the local activism focused on natural areas. In São Paulo, different groups are working to increase the biodiversity and tree cover in the city by planting small forest patches, locally known as pocket forests. These activities are first planned with the local stakeholders, and then the area is prepared for planting, including the eventual removal of pavement, preparation of the soil, among other measures. The act of planting per se is...

This study aimed to use a semi-natural meadow as an ecological restoration tool for the optimisation of ecosystem services and landscape attractiveness of river revetments. River revetments combine bank reinforcement with greening and can resist flood washing and provide waterfront space for human activities; thus, it has become a key functional unit in riparian ecosystems used to foster ecosystem services such as the interception and filtration of polluted surface water, habitat for organisms and aesthetic beauty.

Herbaceous species that naturally occur in habitats with infrequent...
