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.

GIZ ValuES - Cost-benefit-analysis of the Bala dam proposal, Bolivia

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...

GIZ ValuES - Rewarding farmers for reducing sedimentation, Indonesia

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...

GIZ ValuES - Protecting mangroves for local benefits, Philippines

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...

H2020 AQUACROSS Case Study 3 - Danube River Basin - harmonising inland, coastal and marine ecosystem management to achieve aquatic biodiversity targets

Danube River connected sidearm (c) Andrea Funk

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...

H2020 AQUACROSS Case Study 5: Improving integrated management of Natura 2000 sites in the Ria de Aveiro Natura 2000 site, from catchment to coast, Portugal

Aveiro River (c) Ana Lillebo, University of Aveiro

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...

H2020 AQUACROSS Case Study 7 - Biodiversity management for rivers in the Swiss Plateau

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.

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...

Prague Riverfront Concept

Prague Riverfront Concept

„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 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...

Urban gardens in Barcelona: multifunctional green to enhance Nature-Based Thinking in cities

Renaturing Barcelona: various green typologies in the centre of the city. Bellow, on the left: Cover of the government measure “The Programme for Enhancing the Urban Green Infrastructure”. Photo captures: Corina Basnou.

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 Green Corridors Network as the background of a NBS approach in Lisbon, Portugal

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...

Using semi-natural meadow vegetation for restoration of river revetments: A case study in the upper reaches of the Yangtze River

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...
