Air quality, green spaces, and environmental policies

Mayotte, a French overseas department off the coast of East Africa, has a population of 226,915 and faces environmental pressures from climate change, including intensified cyclones and sea level rise. Air quality data is unavailable but likely stable per regional trends. As part of France, it adheres to EU environmental standards with protected marine parks covering 27% of territorial waters. Challenges include waste management and disaster vulnerability, with limited recycling infrastructure.

Air Quality Index

0510

Good

7.0/10

Stable trend

No specific AQI data available for Mayotte; database indicates stable 6-month trend. Regional Indian Ocean islands show good air quality due to low industrialization. French monitoring applies but no local stations reported. Potential concerns from biomass burning and transport emissions.

Water Quality

0510

Good

7.5/10

Water quality managed under French standards with treatment plants serving 80% of population. Groundwater contamination risks from agriculture and sanitation. Surface water used for 70% of supply shows good quality per ARS monitoring. Access to piped water: 92%.

Safe after treatment; occasional bacterial alerts during cyclones.

Recycling System

Limited recycling infrastructure; no specific rate available. Waste collection covers 60% of population with landfill primary disposal. Selective collection pilots for plastic/paper in urban areas (Mamoudzou). EU waste directives implemented but low compliance.

Green Spaces

Mayotte Marine Park protects 27% of territorial waters, one of France's largest. Terrestrial protected areas cover 3% including Mount Choungui reserve. Forest coverage around 25% with mangroves vital for coastal protection. Biodiversity hotspot with 3000 marine species.

Forest Coverage: 25.0%

National Parks: 0

Parc Naturel Marin de Mayotte created 2010; RAMSAR wetlands designated.

Environmental Policies

Follows French/EU environmental laws including Water Framework Directive, Natura 2000 network. Mayotte Climate Plan targets 40% GHG reduction by 2030 vs 1990. Plastic bag ban enforced since 2016. Part of Paris Agreement through France.

Key Policies:

•Mayotte Climate-Air-Energy Plan
•Marine Protected Area Management
•EU Habitats Directive

Renewable Energy: 20% renewable energy by 2025 (solar, biomass); current ~10%.

Natural Disaster Risk

HIGH

High risk from tropical cyclones (season Nov-Apr), coastal flooding, earthquakes. 70% population vulnerable to sea level rise. French civil protection system with Météo-France early warnings.

Climate Change Impacts: Temperatures rose 0.8°C 1981-2020 (Météo-France). Cyclone intensity increased 15% since 1980. Sea level rise 4mm/year observed at Dzaoudzi station. Precipitation extremes up 20% with more intense rain events. Cyclone Kenneth (2019) strongest ever in region: 215km/h winds, $200M damages.

Sustainability Initiatives

Marine Conservation

Mayotte Marine Park established 2010 protects coral reefs, mangroves, sea turtles. 27% territorial waters no-take zones. Patrols reduced illegal fishing 40%.

Renewable Energy

Solar program targets 20MW capacity by 2025. 500 household solar kits distributed 2022-2024. Reduces diesel imports (90% current electricity source).

Waste Reduction

Organic waste composting pilots in 5 communes. Goal: 20% waste diversion by 2026. EU funding supports sorting centers construction.
