## Environment
Kerala has one of India’s most distinctive environments: a tropical coastline, extensive backwaters, midland plains, and the forested slopes of the **Western Ghats**, a globally important biodiversity hotspot.
### Natural setting - **Arabian Sea coastline** along the west - **Backwaters, estuaries, and wetlands** including Vembanad and Ashtamudi systems - **Western Ghats mountains** in the east - Rich river network flowing westward to the sea
### Biodiversity and protected areas Kerala is known for high biodiversity and several protected landscapes, including: - **Periyar Tiger Reserve** - **Eravikulam National Park** - **Silent Valley National Park** - **Wayanad Wildlife Sanctuary** - **Parambikulam Tiger Reserve** - **Thattekad Bird Sanctuary** - **Chinnar Wildlife Sanctuary** - additional reserve forests and conservation areas
### Environmental issues - Flooding during intense monsoon events - Landslides in vulnerable hill districts - Coastal erosion and sea-level-related concerns - Wetland pressure from urbanization and reclamation - Plastic waste and urban solid waste management challenges - River pollution and localized water-quality stress in built-up areas - Quarrying and land-use debates in ecologically sensitive zones
### Air and water quality - Air quality is generally better in many rural and forested areas than in large Indian metros, though urban congestion can cause local pollution episodes. - Water quality varies by source and location; treated municipal water, wells, and surface water each face different risks. - During monsoon and flood periods, contamination risk can increase in some places.
### Sustainability and public action - Kerala has a visible public conversation around ecology, waste reduction, and disaster resilience. - Local governments and citizen groups often support: - decentralized composting - source segregation of waste - river and wetland cleanups - biodiversity clubs in schools - rainwater harvesting - afforestation and mangrove-related initiatives in some coastal belts
### Climate - Tropical monsoon climate - High humidity in lowland and coastal areas - Cooler conditions in elevated hill stations such as Munnar and Wayanad uplands
### Environmental significance - The state’s ecology is central to its agriculture, tourism, fisheries, hydropower, and drinking-water systems. - Because Kerala is densely populated, environmental management is closely tied to land use, transport, housing, and disaster planning.
