Himalayan Infrastructure: Environmental Risk Mitigation



  Nov 29, 2023

Environmental Impact Assessment for Infrastructure in Fragile Regions of Himalayas-2



In the Silkyara Bend region of Uttarakhand, a tunnel disaster has highlighted the critical importance of environmental assessments in infrastructure projects. The incident involved the collapse of a highway tunnel under construction, which tragically ensnared 41 workers. This event has cast a spotlight on the vulnerabilities of the Himalayan terrain, an area prone to ecological fragility due to its composition of unstable soil, crushed rocks, and limestone. The disaster serves as a stark reminder of the potential consequences when large-scale engineering projects overlook comprehensive environmental risk evaluations, especially in regions known for their susceptibility to landslides and flash floods.

Why are environmental studies important before starting large construction projects?

Environmental studies help understand how a project could affect nature, including the risks of landslides and floods, especially in fragile areas like mountain regions.

What is an Environmental Impact Assessment (EIA)?

An EIA is a process where experts study the potential effects of a construction project on the environment before it begins.

How does the terrain's fragility affect construction projects?

Fragile terrains, like those with soft soil and limestone, are more prone to natural disasters, which can be worsened by construction.

What can happen if construction projects ignore environmental risks?

Ignoring environmental risks can lead to serious consequences like landslides or flash floods, which can damage the ecosystem and human settlements.

Why might smaller segments of a project not require an EIA?

Sometimes, smaller project segments are exempt from EIA because they fall below a certain size threshold, but this can overlook the cumulative impact on the environment.

What should be considered during the planning of infrastructure in ecologically sensitive areas?

Planners should carefully weigh the environmental costs against the benefits, considering the increased risk of natural disasters in these areas.
