The Kozhikode-Wayanad twin tunnel project (Anakkampoyil-Kalladi-Meppadi) is a ₹2,100 crore underground road project designed to bypass the congested Thamarassery Ghat road. However, it passes through highly ecologically sensitive areas of the Western Ghats. In July 2024 (two years prior to this incident), Chooralmala and Mundakkai in Wayanad suffered catastrophic landslides that killed over 400 people, raising massive concerns about structural projects in this region.

The Ministry of Environment, Forests and Climate Change (MoEFCC) is the nodal agency in the administrative structure of the Central Government for planning, promotion, and coordination of environmental programs. Under the Environment Impact Assessment (EIA) Notification, 2006, the EAC (Expert Appraisal Committee) is constituted to evaluate the environmental impact of developmental projects and recommend or reject environmental clearances with specific compliance conditions.

In August 2018, Kerala experienced its worst flooding in nearly a century due to unusually high rainfall during the monsoon season. It affected millions, claimed over 480 lives, and triggered hundreds of landslides, particularly in hilly districts like Wayanad and Idukki. It served as a major warning regarding the ecological vulnerability of the Western Ghats.

On August 8, 2019, Kerala was struck by double landslide tragedies: one at Puthumala in Wayanad and another at Kavalappara in neighboring Malappuram. These slides occurred almost simultaneously due to extreme rainfall, burying entire settlements and resulting in over 17 deaths in Puthumala and 59 in Kavalappara, highlighting the regional susceptibility of these hills.

Wayanad is a mountainous district that lacks major super-specialty and tertiary healthcare institutions. For critical medical emergencies, surgeries, or advanced treatments, residents must travel to the Government Medical College in neighboring Kozhikode. The Thamarassery Ghat road, which connects the two districts, is frequently blocked by traffic and landslides, prompting demands for an all-weather tunnel road to ensure quick medical access.

In April 2026, the Supreme Court of India dismissed appeals challenging the environmental clearance granted to the Kozhikode-Wayanad twin-tunnel project. The court allowed the state government to proceed with the construction, accepting arguments that the tunnel would not damage the forest canopy above and would significantly improve connectivity for the people of Wayanad.

In hill road and tunnel construction, excavation generates massive quantities of loose rock and soil (muck/debris). The MoEFCC guidelines mandate that this debris must not be dumped on hill slopes, as it can be easily washed away during rains, triggering landslides. It must be transported to pre-designated, scientifically engineered dumping sites with retaining walls to prevent ecological hazards.

The Western Ghats are a global biodiversity hotspot, but they are also geologically fragile due to steep slopes, high weathering of rocks, and heavy monsoon rains. Studies by committees like the Madhav Gadgil (2011) and K. Kasturirangan (2013) panels warned against heavy construction, quarrying, and land-use changes in ecologically sensitive zones, stating that human interventions significantly increase landslide risks.

An environmental audit is a systematic, documented evaluation of how well an organization or project complies with environmental regulations. Under Indian environmental law, projects must regularly submit compliance reports. However, calls for an ‘independent audit’ highlight the need for third-party specialists (rather than self-reporting by builders or state bodies) to verify that safety standards are genuinely being implemented.

The Sendai Framework for Disaster Risk Reduction (2015-2030) is a major international agreement that shifts the focus of disaster management from reactive response (managing disasters after they strike) to proactive prevention and risk reduction. It emphasizes understanding disaster risk, strengthening governance, investing in resilience, and enhancing disaster preparedness for an effective response and ‘Building Back Better’.
