By making an alliance with a local civil association with a permanent presence in the area, INECC was able to better focus human and economic resources on the reforestation of 25 hectares of mangroves and the 3km clearing of channels for the restitution of the water flows of the wetland.

Mangrove reforestation was carried out using the "chinampas" technique (1 x 1m floating mud mounds) which served as a platform for the optimum growth of mangrove seedlings.

This technique, previously used in other neighboring areas, includes an ecological monitoring phase as well as geo-referenced photographic monitoring points to identify the evolution of the monthly growth of the seedlings in each of the almost six thousand established chinampas.

In addition, the direct participation of the communities in the activities provided empirical knowledge about the particularities of the land, and essential labor to dig open, by hand, the channels. The combination of technical and empirical knowledge has created evidence for the ecological modification of the landscape: the establishment of the chinampas has elevated the topography of the site, and the hydrological flows have brought nutrients and oxygen, creating ecological niches that the species occupy to restore the trophic chain.

CityAdapt’s various implementation activities are carried out with demonstration sites to showcase benefits to surrounding populations and inspire replication. This includes demonstration sites for edible mushroom cultivation, urban gardens, roof rainwater harvesting systems, beekeeping, water infiltration systems, agroforestry, and other activities.

CityAdapt also emphasizes learning from project activities, especially for planning officials and communities to take ownership and help them continue after project end. It has therefore produced or is producing an array of knowledge products, including manuals, policy briefs, case studies, technical guidelines, and education material for children. A key aspect of this work has been highlighting NbS’ cost-effectiveness in comparison to conventional solutions (see story maps).

One key is a virtual class with 45 students that work on adaptation-related issues in their respective 17 countries. All the students reported an across-the-board improvement in their knowledge of NbS for urban adaptation. This class model will now be expanded to other regions. These learning components help to build the case for further NbS integration in urban planning and policy while spreading CityAdapt’s lessons to other actors interested in using NbS for their respective cities.

These three decision-making tools were crucial to address power dynamics and promote stakeholders' participation and engagement in collective action in the National Park:

• An analytical tool to characterize types of governance arrangements in the protected area. Formal and informal governance arrangements were classified in terms of stakeholders’ responsibility (shared vs. concentrated) and influence (equal vs. unequal) into four types: prescriptive, informative, consultative, and cooperative. By applying this tool in the National Park we identified challenges for more socially inclusive conservation while enhancing existing participatory mechanisms and delineating new ones;
• Theatre-based facilitation techniques to address power dynamics between stakeholders. By using them in a virtual workshop, participants deliberated on their roles and power relations around conservation governance and how these may be reconciled to improve collaboration;
• A context-specific boundary object to facilitate collective action for conservation governance. Using this graphical tool in a workshop, participants assessed their level of willingness to put several strategies into practice. The tool visualized the results graphically as a proxy of the potential willingness to move from theory to practice.

These three tools help to identify visions and elaborate future scenarios, in a participatory way, for protected areas management:

• Participatory mapping (PGIS), a tool to visualize information in a particular geographical context focusing on a certain issue of interest. This tool was used in surveys to elicit the residents’ visions based on perceptions of landscape values and local knowledge;
• Streamline, an open-source narrative synthesis tool that integrates graphics in the form of canvases and tiles, facilitating interviews and discussion groups in a creative and stimulating way. Streamline was used with stakeholders’ expressing their values and preferences for management actions, and sharing their knowledge of changes in the landscape;
• Participatory scenario planning exercise, a deliberative process that was facilitated about plausible and desired futures through a two-day online workshop (due to the Covid-19 pandemic) with stakeholders. Based on the current socio-ecological conditions and the factors driving change, participants weighed up what could happen in the coming 20 years, discussed implications for biodiversity conservation and the quality of life of those who currently enjoy the ecosystem services it provides, whilst identifying the strategies to address them.

To facilitate place-based processes that foster inclusive conservation it is necessary to collect local/traditional knowledge, views, and values from multiple stakeholders. Some methods to gather such information were used in the Sierra de Guadarrama National Park:

• Oral histories and historical datasets review to reconstruct how past visions and drivers of environmental impact have changed over the last 50 years and inform current and future conservation goals;
• Interviews with local stakeholders on 1) how participation works in the protected area and potential barriers/opportunities for more social engagement, and 2) their visions for park management, the values and knowledge that underpin the visions, and their perceptions of landscape changes and the underlying drivers;
• Face-to-face surveys with residents, including participatory mapping tools (i.e. Maptionnaire) about landscape values and ecological knowledge. Online surveys with local stakeholders to identify changes in their visions, values and perceptions of the landscape after the COVID-19 pandemic; and
• Deliberative processes embedded in a participatory scenario planning exercise that used cognitive and emotional maps to collect collective knowledge of the protected area while capturing intertwined affective relationships.

The systematic monitoring of planted trees that is conducted by HAF and the gathering and registering of data of trees planted, including GPS locations, height, diameter, survival rates, and social benefits. The integrated tree monitoring system, called AKVO, was developed by Ecosia, a German organization which plants trees using revenue generated from their search engine. Trained in the use of this application, the monitoring team disperses throughout the regions, visiting the farmers and monitoring the trees that were planted during the previous planting season. Stored in a shared database, the information collected by the team in collaboration with local nursery caretakers will enhance informed decision-making at all levels of governance and across sectors by filling gaps in knowledge and precedence regarding practical application of resource management. 

Without doubt, stone tidal weirs contribute to marine biodiversity.  In comparison with intertidal zoneswithout stone tidal weir, those with stone tidal weirs have host diverse marine species.

Once stone tidal weirs are abandoned, the less fish is caught.  As the attention of local people shifts to destructive modern fishery,  all aspects connected to cultural diversity would also be disappeared.  In order to maintain coastal communities sustainable, they must not lose their biocultural diversity; stone tidal weirs could be served as an icon of such diversity as well. The UNESCO UNITWIN university network researches and studies how stone tidal weirs in safeguarding biocultural diversity.

Stone tidal weirs are the most vulnerable against global climate change.  Recent field surveys and participant-observations of them prove that many stone tidal weirs have been abandoned or simply left broken, owing mainly to ocean environmental change.  If sea levels rise more than 1 meter, all stone tidal weirs on the earth do not function as fishing gear.   Once they are destroyed by storms or high waves, some coastal communities cannot afford to repair them, leaving simply them abandoned.  All over the world, indeed, the underwater cultural heritage of stone tidal weirs is in danger of closing down, as cultural heritage as well as traditional fishing gear.  For the purpose of understanding their vulnerability properly, the assessment of long-termed tidal range changes around stone tidal weirs, the measuring of coastal erosions faced by them, and the impact monitor of typhoons or high waves which destroy stone tidal weirs have been conducted, occasionally by help of remote sensing data.

The underwater cultural heritage of stone tidal weirs was originally born as a local fishing mechanism. The processes are based on a rich local traditional ecological knowledge, which brought on by members of local coastal communities. Traditionally, local communities used stone tidal weirs twice a month during the spring tide; a custom that has been preventing overfishing by locals. At high tide they sometimes functioned as fishponds. 

The traditional ecological knowledge, for instance, on non-fishing periods, as well as that on fishery-related ritual activities such as beach opening ceremonies, is widely observed at coastal communities but it is rapidly disappearing before being recorded properly by anthropologists or archaeologists. As stone tidal weirs are easily broken by typhoons or high waves, frequent community-led repairing works based on traditional knowledge are absolutely needed. In case stone tidal weirs are abandoned, however, both communal spirit and traditional ecological knowledge would extinct.  

The nature of Herculaneum’s burial 2000 years ago meant that open-air excavation in the early 20th c. revealed an extraordinary level of preservation of the Roman town but had to be accompanied by the stabilization of these multistorey ruins, and the reinstatement of roads and drainage systems. The site today requires conservation of the archaeological fabric but also of these aging restoration interventions, and at an urban scale.

However, efforts at Herculaneum in the late 20th c. approached the site as a series of individual elements. This was partly due to limited access to interdisciplinary expertise and steady funding sources – sporadic capital funding for one-off localised projects predominated.

With the turn of the millennium, a new approach was taken that mapped conservation issues and interdependencies between them across the entire site, and acted on them. Initial efforts focused on resolving situations in areas at risk of collapse or with vulnerable decorative features. Over time the focus shifted to long-term strategies for reducing the causes of decay and developing site-wide maintenance cycles sustainable by the public authority alone so that the site would not revert back. With these now entirely sustained by the public partner the overarching objective has been achieved.
