The Recovery of Cienaga Juan Polo project is primarily aimed at reopening the natural mouth of the Manzanillos to restore water flow between the sea and the Juan Polo coastal wetland, which has been affected by human activities leading to high salinity and water stagnation issues (ref 2). The project is led by Fundacion Serena del Mar. Environmental and social sustainability are core components of the project design, which has included extensive community consultations since 2013. These consultations have resulted in agreements covering employment opportunities, education, and infrastructure development (ref 2). Key implementation activities include the reforestation of mangroves and targeted interventions to address ecological degradation, such as increased salinity, water stagnation, and biodiversity loss (ref 2). The project also seeks to enhance the quality of life for surrounding communities by restoring traditional economic activities, particularly fishing, and integrating sustainable urban planning elements such as canals, sluices, and navigable waterways. These features are designed to support the development of a "blue corridor" for aquatic mobility within Serena del Mar (ref 2, 3). In addition, it also contributes to local capacity building through environmental education programs that engage community members, researchers, and NGOs in biodiversity monitoring and sustainable practices​ (ref 1).

Focus

Coastal landscape management or protection, Coastal ecosystems restoration and maintenance (mangroves, dunes, saltplains, underwater meadows), Ecological restoration of ecosystems, Restoration of mangroves, Restoration and protection of ecosystems (including water ecosystems), Protection of natural ecosystems, Habitat conservation, Knowledge creation and awareness raising, Educational and awareness raising programs, Scientific research of biodiversity or ecosystems, Improved governance of green or blue areas, Establishment of inclusive governance mechanisms involving local communities, Monitoring and maintenance of habitats and/or biodiversity, Citizen science and monitoring initiatives (e.g. species observations, habitat assessments, and data collection efforts)

Project objectives

- Reopen the natural mouth of the Manzanillos to restore water flow and improve water quality and oxygenation in the Ciénaga de Juan Polo​ (ref 2) - Reforestation of mangroves and conservation of local biodiversity to stabilize ecosystems (ref 2) - Enhance the quality of life for local communities by restoring traditional practices such as fishing and promoting ecotourism​ (ref 2) - Create a "blue corridor" for aquatic mobility and connectivity (ref 2) - Implementing environmental education programs and capacity-building activities to empower local communities and foster sustainable practices​ (ref 3) - Foster community participation in planning and decision-making to ensure transparency and equitable development (ref 2).

Implementation activities

Since 2013, consultations have been carried out to guide the planning of the project (ref 2). These have evolved into ongoing consultations with local communities to negotiate agreements on employment, education, and infrastructure as part of the development process (ref 2). To date, 26,000 mangroves have been planted around the water bodies within Serena del Mar, as part of a planned total of 42,000 individuals from 32 native species. An additional 70,000 trees are scheduled for planting in 2024 (ref 2). Complementary activities include engagement with communities and stakeholders to discuss project stages; training for entrepreneurs on wildlife management; workshops on ecosystem services and sustainable resource use in the Ciénaga Juan Polo; a biocensus to monitor biodiversity; participatory wildlife monitoring sessions to assess species and habitat data; implementation of sustainable forest use practices with community involvement and community workshops on legal frameworks and participatory tools to strengthen local governance and conservation (ref 2). As part of capacity-building efforts, 35 technicians and environmental engineers, together with youth and leading teachers as well as participants from ecotourism companies, received training on methods for observing the biodiversity of the mangrove ecosystems in the Juan Polo and La Virge wetlands (ref 1).

Biodiversity conservation or restoration-focused activities

Biodiversity restoration:

  • Rehabilitate and restore damaged or destroyed ecosystems

Main beneficiaries

  • Citizens or community groups
  • Coastal-dependent communities (e.g. small-scale fishers, coastal farmers, and indigenous peoples)
  • Young people and children

Governance

Management set-up

  • Led by non-government actors

Type of initiating organisation

  • Non-government organisation/civil society

Participatory approaches/ community involvement

  • Co-planning (e.g. stakeholder workshops, focus groups, participatory mapping)
  • Taskforce groups
  • Dissemination of information and education
  • Consultation (e.g. workshop, surveys, community meetings, town halls)

Details on the roles of the organisations involved in the project

Since 2018, the Fundación Serena del Mar has been coordinating environmental activities in the Juan Polo and La Virgen lagoons (ref 4). The Foundation was established in the context of the Serena del Mar Mega Project, a large-scale urban development initiative, and in response to concerns raised by the local community about the risks such a project could pose to territorial integrity and the surrounding ecosystems (ref 5). Alongside the Foundation, various actors participate in the project, including government bodies, private entities, community organizations, educational institutions, and non-governmental organizations (NGOs). Local leaders and community organizations are actively engaged in environmental awareness activities and in decision-making processes to ensure that development is aligned with environmental and social priorities (refs 1, 2, 3).
