The implementation of a new project requires the social acceptance of the local population. The objectives, strategies to be followed, the conceptual approach to implementation (in this case ecosystem-based adaptation to climate change) needs to be communicated and the communication and coordination mechanisms for the implementation need to be established.

The EbA Amazonia project, implemented jointly with SERNANP and ECAs (Ejecutor del Contrato de Administración de la Reserva / Executor of the Administrative Contract of the Communal Reserve) -representatives of communities - should present a united front with all the actors involved. So from the  day that the communities entered, the project established concrete roles for all actors in the implementation of activities (e.g. SERNANP and ECAs). This generates a vision of unity and projection of activities beyond the life of the project (sustainability) since the SERNANP and ECAs are entities that perpetually interact with the local population.

Given the history of the Ruhr region, the Heerener Mühlbach was a canalised water body used as an open wastewater system. Conducting a mixture of waste and storm water in a straight concrete bed, the water body got classified as heavily modified according to the EU Water Framework Directive and required that a number of problems be resolved. Discharges of wastewater in the stream derogated the ecosystem tremendously and the concrete bed of the water body and the specific management of the banks harmed biodiversity. Another problem was the dangerous shape of the canal which prohibited the recreational use of the water body. And finally, bad smell regularly disturbed the neighbourhood. As a first essential step towards ecologic enhancement, a sewer pipe was placed underground along the river. The concrete bed was then removed (apart from few exceptions, e.g. under bridges), which led the river to flow on a new sole that was higher and wider than before and meander where possible. The hard banks were converted into nature-like banks. The initial plantation is complemented by wild and natural vegetation: green plants have the chance to flourish along the blue water body.

CONANP has supported a new women’s cooperative (“las orchidias”) aimed at providing additional and innovative, non-capital intensive, eco-touristic services, and thus delivering additional sources of income to climate-change threatened lobster fishing families. Examples include: bicycle and kayak tours, and environmental interpretation routes. CONANP has provided support in the form of : a) Training for multiple actors b) Financing, c) Certification of activities and services d) Organizing women’s peer-to-peer knowledge exchange and mentoring The additional co-benefits of this approach have been to increase the confidence and self-esteem of local housewives, and to raise their position in the eyes of their families, as well as to provide a new potential organized group as a platform for future activities.

Prior to the restoration, Mayesbrook Park was unloved and underused. For the project to be a success, it was thus important to reconnect the neighbouring communities with the park and its planned refurbishment. Extensive public consultation helped the partners address local concerns about the park and served to ensure significant social benefits, such as an increased number of visitors in the park, as well as a greater feeling of safety. As the park was home to criminal activities and antisocial behavior prior to reformation, the use of an on-site ranger has helped to reduce this threat and provide greater comfort to visitors and the surrounding communities. In addition, Natural England also worked with the schools to see how the park could be most relevant to their needs and based new natural play facilities and trail markers in the on designs by these children. The improvement in landscape, social and aesthetic value helped shape new recreation facilities and enabled better access for park users.

An extensive and iterative process of stakeholder engagement was initiated during the design and execution of this project. The process involved a ‘rolling programme’ of consultation with local residents, representatives from the local school, practitioners, city staff and many others in order to build awareness about the SuDS retrofit, its benefits and costs, and to obtain public perspectives on the desired design. This included regular meetings, community workshops, and informal gatherings at sports and cultural events. The approach became increasingly open and consultative, with approximately one fifth of the tenants in the area having participated in dialogue meetings about the project. Amongst other topics, safety issues related to open water areas (e.g. retention pools) were discussed with residents as well as the potential loss of particular recreational opportunities in the area. In many cases, comments and concerns from stakeholders were taken into account and addressed in redesigned SuDS plans.

While the core purpose of the project was to address flooding related to an over-utilized combined sewage system, the neighbourhood of Augustenborg was also in a state of socioeconomic decline prior to the urban regeneration project. Thus, the generation of socio-economic benefits became central to the project’s goals, such as improving the livability and aesthetics of the neighborhood, alongside biodiversity objectives. Furthermore, the project is part of a larger regeneration initiative within the neighbourhood of Augustenborg, which is also nested within ambitious sustainability plans for the City of Malmö. More specifically, the ‘Eco-city Augustenborg’ initiative aimed to transform Augustenborg into a socially, ecologically, and economically sustainable settlement. Ultimately, the work has represented a significant transformation of the neighborhood, and has become emblematic of a more pervasive shift towards sustainability. It has also resulted in the development of several businesses in the area of water innovation. Media coverage and public relations value are viewed as being additional benefs to the city and its residents.

A partnership between the Malmö housing company, Malmö water and city planners was a critical ingredient in the implementation of this project. Technical expertise was required from each of these partners to ensure appropriate design, and funding of the project was also collaboratively provided. Further components of this successful partnership included stakeholder engagement, the presence of sophisticated technical expertise, and a high level policy directive in support of experimentation. Understanding of the local ecosystems was not critical, but project designers had to possess a very detailed understanding of the frequency and severity of local floods.

Within the Wallasea Project, land-raising and landscape engineering was innovatively approached by creating a novel public private partnership. Materials from the Crossrail tunneling project were transported to a low-lying coastal area at high risk of flooding, in order to raise the land. The project thus established a precedent for using largely waste material generated by a major infrastructure project to meet biodiversity conservation and climate change adaptation aims elsewhere. Financing stemmed from both the private company Crossrail as well as from the Environment Agency, with all parties profiting due to the economic as well as environmental benefits set off by recycling the leftover materials. With Crossrail on board as a delivery partner, the project represents a partnership between Europe's largest civil engineering project and Europe's largest intertidal habitat creation project.

The implementation process began with the founding of the PHOENIX-See Entwicklungsgesellschaft (EG ) - as a subsidiary of the municipal utility company - to manage this large-scale project. An external project leader was employed and expert engineering offices were contracted. The EG was involved on all topics relating to water management of the Emscher and the Pheonix lake. From the governmental side, a large number of agencies were involved in the process. Public participation was realized through formal and informal meetings and discussions. Of importance were also the feasibility and assessment studies initiated in 2001 to improve the design of the solution and convince decision makers that the risks involved were acceptable. The plan was finally approved in 2005, with digging operations starting in 2006. A year later, the new wastewater sewer was finished and in 2009 the renatured Emscher started to flow in its new bed. Finally, the lake was flooded in 2010 and officially opened in 2011. The construction of houses along the lake started in this period and in 2013 the Entwicklungsgesellschaft “delivered” the lake back to the city of Dortmund.

As this solution serves various goals and meets several objectives, it was possible to secure sufficient funding from diverse parties, domains and funding bodies to cover the entire implementation of the project. In the case of the creation of Lake Phoenix, this included funding for water management from the water board; funding for ecology from the ecological funding program by the federal state; funding for urban development from etc. The water board, for instance, provided the amount of money that was already budgeted for the construction of a flood retention basin. This basin was not needed anymore, as the lake solution already provided the required flood retention function. Some additional potential funding sources were not even used in the end, because it would have slowed down the marketing of the real estate and would have tied the project to certain restrictions, which were not desired by the decision-makers.
