Eco-sensitive Areas (ESA) in the Western Ghats

Syllabus: GS3/Biodiversity and Conservation

Context

• The Union Government issued the sixth draft notification designating approximately 56,825.7 square kilometers of the Western Ghats as an Ecologically Sensitive Area (ESA) spanning six states: Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.

About

• The notification aims to protect the rich biodiversity of the Western Ghats by imposing restrictions on activities such as mining, quarrying, and large-scale construction within the ESA.
• It had provided the states a 60-day window seeking their views and objections on the villages demarcated as ESA.

Eco-Sensitive Zone (ESZ)

• In 2002, it was decided that an area around each Protected Areas, requires to be notified as an Eco-Sensitive Zone for creating a buffer as further protection around Protected Areas (PAs).
  • The very purpose of declaring ESZ is to create some kind of “Shock Absorber” for the specialized Ecosystem, such as protected areas or other natural sites.
• Ecologically Sensitive Areas (ESA) have unique biological resources, which require special attention for their conservation.
  • These areas often contain rare or endangered species, critical habitats, unique ecosystems, or vital natural resources that are essential for maintaining biodiversity and ecosystem functions.
• On the basis of proposals and recommendations of the State Government, the Ministry notified the ESZs under the Environment (Protection) Act, 1986. 

Need to Declare Western Ghats as ESAs

• The entire Western Ghats is the second most landslide-prone region of the country after the Himalayas. 
• Absence of ESA cover to Western Ghats resulted in continuation of several environmentally-hazardous human activities, including massive deforestation for mining and construction over the years, leading to loosening of soil and affecting hillside stability.
• Biodiversity: The Western Ghats are considered one of the 8 “hottest hotspots” of biological diversity in the world.
  • Covering an area just under 6% of India, the Western Ghats contain more than 30% of all plant, fish, herpeto-fauna, bird, and mammal species found in India. 
  • Many species are endemic, such as the Nilgiri tahr (Hemitragus hylocrius) and the lion-tailed macaque (Macaca silenus). 
  • 50% of India’s amphibians and 67% of fish species are endemic to this region.
• The Western Ghats perform important hydrological and watershed functions.
  • Approximately 245 million people live in the peninsular Indian states that receive most of their water supply from rivers originating in the Western Ghats.
• Conservation: In 2012, the Western Ghats were inscribed as a UNESCO World Heritage Site due to their exceptional biodiversity and ecological value.
  • Several areas of the Western Ghats are designated as protected areas, including national parks and wildlife sanctuaries like Silent Valley National Park, Periyar Wildlife Sanctuary, and Agasthyakoodam.

State’s Reaction

• The Chief Ministers argued that the proposed conservation schemes were too restrictive to allow any development work in the hills that run parallel to the western coast. 
• Maharashtra and Goa sought a reduction in the extent of ESA within the respective states for allowing development works.
• The then govt in Karnataka urged the Centre in 2022 to withdraw the draft arguing that it would adversely affect the livelihood of the people in the state. 
• The illegal mining lobby and tourism industry put pressure on the government to delay the notification.

Recommendations of Committees on Western Ghats

• Gadgil Report (2011)
  • Recommended declaring the entire Western Ghats as an ESA.
  • Strong focus on restricting developmental activities across the region.
  • Three-tier categorization of the region: It created three categories of protection regimes and listed activities that would be allowed in each based on the level of ecological richness and land use.
  • Emphasized forest rights and sustainable livelihoods.
  • The report recommended the creation of a Western Ghats Ecological Authority (WGEA) at both the national and state levels to monitor and enforce conservation efforts.
  • Environmentalists supported, but state governments and industries strongly opposed.
• Kasturirangan Report (High-Level Working Group Report, 2013)
  • Recommended declaring only 37% of the region as an ESA.
  • Focused on regulating development in identified sensitive areas while allowing more flexibility in other regions.
  • Focused on core ecologically sensitive areas.
  • Focused more on development balance and economic activities.
  • Recognized the importance of sustainable livelihoods, but with less emphasis on forest rights.
  • Argued for strengthening the existing framework of environmental clearances and setting up of a state-of-the-art monitoring agency. 
  • State governments and industries found it more balanced, though some environmentalists felt it was too lenient.

Conclusion

• The Western Ghats are inhabited even in the areas categorised as natural landscapes. 
• It is not possible to plan for Western Ghats only as a fenced-in wilderness zone.
  • This is the difference between the natural landscapes of a densely populated country like India and the wilderness zones of many other countries.
• Policymakers have to create a fine balance and promote a development that is sustainable in the cultural and natural landscapes.
