Nepal's Chure Hills Decline, Threatening Tarai Water Security

The Kathmandu Post highlights a critical environmental crisis unfolding in Nepal's Chure hills, a region essential for the water security of the vast Tarai plains. For years, these fragile hills have been overexploited, leading to severe ecological degradation. This degradation is now directly impacting the lives of millions in the Tarai, who rely on groundwater that is replenished by the Chure.

The fragile Chure range, long recognised as the principal recharge zone for groundwater in the Tarai, is steadily losing its ecological function, pushing vast stretches of fertile plains towards an unprecedented water crisis.

The article details how increased soil erosion, landslides, and the rampant extraction of sand and gravel from riverbeds are crippling the Chure's ability to absorb and store water. This is not a new problem, but a culmination of decades of unsustainable practices, exacerbated by erratic rainfall patterns and rapid settlement expansion. The consequences are stark: drying traditional wells and ineffective tube wells, leaving communities parched.

The weak geological structure of the Chure, compounded by intense human activity, has significantly reduced the land’s natural ability to absorb and store water.

From our perspective at The Kathmandu Post, this crisis underscores a critical failure in environmental governance. While the government has initiatives like the President Chure-Tarai Madhesh Conservation Development Committee, their effectiveness is clearly limited against the scale of human activity. The story of water scarcity in the Tarai is a story of Nepal's own making, a direct result of prioritizing short-term economic gains from resource extraction over long-term ecological sustainability. This is a uniquely Nepali challenge, where the health of our vital mountain and hill ecosystems directly dictates the survival of our plains communities.

Last year, many Tarai districts faced an acute shortage of water. For water to reach the plains, the Chure must recharge. But recharge has declined, and the situation is likely to deteriorate further.
