## Environment
Karnataka has striking environmental diversity, from the **Western Ghats and Arabian Sea coast** to the **Deccan Plateau**, river valleys, dry interior zones, and major urban lake systems.
### Natural setting - The state includes: - Coastal districts along the Arabian Sea - The biodiverse **Western Ghats**, a globally important mountain ecosystem - Forested hill ranges, coffee-growing areas, and wildlife corridors - Interior plains with agriculture, scrubland, tanks, and river basins
### Protected areas and biodiversity Karnataka is known for an extensive protected-area network, including: - **Bandipur National Park** - **Nagarahole National Park** (Rajiv Gandhi National Park) - **Bannerghatta National Park** - **Kudremukh National Park** - **Anshi/Kali Tiger Reserve** - **Bhadra Tiger Reserve** - **Dandeli Wildlife Sanctuary** - **Ranganathittu Bird Sanctuary** - **Pushpagiri Wildlife Sanctuary** - **Brahmagiri Wildlife Sanctuary**
These areas support elephants, tigers, gaurs, deer, primates, rich birdlife, and endemic Western Ghats flora and fauna.
### Air quality - Air quality is generally best in forested, hilly, and less industrial areas. - **Bengaluru and other growing cities** can experience particulate pollution from traffic, dust, construction, and seasonal burning. - AQI conditions fluctuate by weather and season; winter inversions can worsen pollution locally.
### Water and lakes - Karnataka depends on major river systems including the **Cauvery (Kaveri)**, **Krishna**, **Tungabhadra**, **Sharavathi**, and **Netravati**. - Water quality varies widely by watershed and urbanization level. - Bengaluru’s lakes are ecologically and socially important, though some have faced sewage inflow, encroachment, or foaming/pollution episodes.
### Climate and sustainability challenges - Deforestation pressure in some areas - Urban sprawl and lake/wetland stress - Groundwater depletion, especially in fast-growing urban and semi-arid zones - Solid waste management in expanding cities - Human-wildlife conflict near forest edges - Flood-drought cycles tied to monsoon variability
### Sustainability efforts - Solar power expansion and renewable energy leadership in parts of the state - Lake rejuvenation projects in urban areas - Waste segregation and recycling campaigns - Watershed development and rainwater harvesting efforts - Ecotourism and conservation programs in forest districts
| Environmental theme | Karnataka context | |---|---| | Major ecosystem | Western Ghats + Deccan Plateau | | Key issue in cities | Air pollution, waste, water stress | | Key rural issue | Water variability, land use pressure | | Biodiversity significance | Very high, especially in Ghats forests | | Climate risk | Floods, droughts, heat, landslides |
