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 river is a citywide public space.“

„Riverfront throughout the city are a coherent space, and their development, even in sub-sections, must always be addressed in a citywide context.“

The river and its banks are an essential city-forming element, and this is how the city should approach them. Until now, Prague lacked a concept for developing the vast potential of the river and its environments. The Prague Riverfront Concept, approved in 2014, rectifies this situation. Many of the most attractive riverside localities have been neglected, poorly managed...

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...

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.

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...

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 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...

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 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.

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.

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...

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.

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...

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  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.

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 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...

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).

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...

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.

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.
