Historical Background and Urban Transformation

Originally a vast area of mangroves and Atlantic Forest, the site surrounding Lagoa da Jansen served as a crucial ecological buffer for São Luís. The lagoon’s name is believed to originate from a Dutch settler, Jansen, during the 17th-century Dutch occupation, though this remains anecdotal.

Rapid urbanization in the 1970s and 1980s led to significant environmental changes, including the construction of major roads and bridges and the encroachment of real estate developments (source). Public outcry over environmental degradation led to the area’s designation as a protected zone, and it was officially established as a state park by State Law No. 5.685 in 1993. Further regulatory protection was attempted with its classification as an Área de Proteção Ambiental (APA) in 2012, though legal ambiguities persist (source).

Ecological Importance and Environmental Challenges

Ecosystem Services and Biodiversity

The park covers approximately 150-196 hectares (depending on referenced delineations), preserving remnants of mangrove and Atlantic Forest ecosystems. These habitats provide crucial services: regulating microclimates, filtering water, preventing coastal erosion, and supporting a range of native species—birds, fish, and small mammals (source).

Environmental Pressures

Urban development has led to pollution, habitat loss, and water quality deterioration. Untreated sewage discharge and organic matter buildup have resulted in periodic foul odors and algal blooms. While sewage discharge points have been reduced significantly in recent years, ongoing management is necessary to restore and maintain the lagoon’s ecological health.

Restoration Efforts

Interventions such as mangrove replanting, improved water circulation, and ongoing monitoring reflect the park’s commitment to sustainability. Environmental education programs and community engagement initiatives are also integral to restoration and protection efforts.

Management, Legal Status, and Future Prospects

Legal and Institutional Context

The park’s legal framework is evolving. Originally established in 1993, the area’s ambiguous status—especially after a failed APA re-designation in 2012—complicates management, funding, and enforcement.

Challenges and Opportunities

Ongoing issues include water pollution, inadequate sanitation facilities, and inconsistent infrastructure maintenance. Addressing these requires improved investment, legal clarity, and stakeholder engagement.

Future Directions

Sanitation Projects: Continued sewage management and water quality monitoring.
Community Engagement: Inclusion of local vendors, fishers, and residents in park planning.
