The Wayanad landslides (2024) highlight the need for ecologically sensitive land-use planning in the Western Ghats. Analyse.

On 30 July 2024, debris flows at Mundakkai–Chooralmala in Wayanad killed hundreds of people. The Geological Survey of India (GSI) traced the trigger to water pressure building up in soil soaked by nonstop rain [1]. Rain is the trigger, but land use largely decides how big the losses are. That makes land use the main lever planning can control.

1. The natural trigger: fragile slopes in a warming climate

• Saturated slopes: heavy rain fell on soil already soaked by two months of monsoon [1][2].
• Climate change: global warming made heavy one-day rainfall about 10% more intense. Models project a further ~4% rise at 2°C of warming [2]. The hazard will grow.

2. Human factors that made it worse

• Forest loss and quarrying: forest cover fell by about 62%, and quarrying may have made the slopes more likely to slide [2].
• Exposure on slopes: the affected zone had tea plantations and mixed crops below forested upper slopes [1].
• Regulatory vacuum: the Western Ghats ESA under the Environment (Protection) Act, 1986 is still only a draft, re-issued several times since 2014. States have asked for more deliberation on its extent [4].

3. What ecologically sensitive planning requires

• Graded zoning: the Kasturirangan HLWG (2013) used the village as the unit of protection. Any village with ≥20% ecologically sensitive area is marked as ESA. Inside the ESA, mining, quarrying, red-category industries and large townships are barred [3]. Farming is not.
• Hazard-led permissions: building approvals should follow landslide hazard zonation maps under NDMA's Landslide Risk Management Strategy (2019) [5].
• Local voice: the Gadgil panel (2011) wanted gram sabhas to have a say on quarries and large projects.

4. Limits of the argument

• The evidence linking land-use change to landslide risk in Wayanad is mixed [2]. An ESA lowers risk over the long term. It cannot stop extreme rain.
• Early warning, slope reinforcement and moving people out of exposed areas are still essential [2].
• In densely settled Kerala, satellite-drawn boundaries need checking on the ground, village by village. Otherwise excluding everything and restricting everything will both fail.

Overall, Wayanad shows that rainfall, deforestation and unplanned settlement on steep slopes together turned a hazard into a disaster. The way forward is to finalise the ESA with ground-verified, hazard-informed village maps. It should be paired with early warning systems and decision-making by gram sabhas. This fits the Sendai Framework and SDG 15 (Life on Land), and treats conservation as protection for people, not a cost to them.
