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.

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.

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.

The AQUACROSSCase Study examines the implications of the regulation on Invasive Alien Species (IAS) (i.e. non-native plants and animals harming the local ecosystem) for practical management in Lough Erne, Northern Ireland, in the context of existing environmental commitments under EU legislation.

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.

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...

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 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

Restoring river-floodplains to protect biodiversity: The Danube’s river biodiversity is threatened by changes to hydrology and geomorphology (so-called hydro-morphological alterations), such as disconnection of floodplains. Multiple human activities, including the construction of hydropower plants, expansion of agriculture, and large-scale river regulation measures to increase navigation and flood protection are resulting in an ongoing loss of habitat and biodiversity. Our aim: In this Case Study, we apply the AQUACROSS Assessment Framework to identify how management of...

To reduce the flood risk, calm traffic and increase community involvement and awareness of sustainable urban drainage systems. To improve water quality in the River Trym.

Using the widely used Policy Support System tools at www.policysupport.org as a basis, we built an insurance industry-relevant policy support system called Eco:Actuary. The objective of this project is to to co-develop and test the Eco:Actuary with NAIAD project partners & stakeholders in the fluvial non-tidal Thames as a DEMO catchment in the NAIAD project. 

EcoActuary is an open-access catastrophe model capable of assessing the impact of NbS on local and downstream assets at risk of flood.  It simulates a minimum of 1200 spatial...

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...

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.

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...

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.

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.

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

The 2010 city-region plan ‘Structural Vision: Amsterdam 2040’, managed by the Department of Physical Planning, set the investment and project ambitions for the period 2010-2040. The strategy seeks to fulfil the vision of a creative and varied city, with an integrated public transport network, high quality urban planning, and investment in recreational green spaces, water and renewable energies. Water-related hazards, such as floods and storm surges, are managed at all levels - city, regional and national. The ‘Agenda Groen 2015-2018’ (Green Agenda 2015-2018) includes specific ‘...

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.

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...

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...

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.

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...

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.

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 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...
