Changing Rainfall Patterns Contribute to Rising Landslide Incidents in Uttarakhand This Monsoon

In Uttarakhand, the shift in rainfall patterns has significantly contributed to increased landslide incidents during this monsoon season. Dr. Sunil Nautiyal, Director of the GB Pant National Himalayan Environment Institute in Almora, highlighted that climate change and the fragile nature of the Himalayan region have exacerbated this issue. The region experienced widespread rainfall only between 13 and 15 September, with localised rain dominating the rest of the monsoon period.

According to sources from the Meteorological Department in Uttarakhand, an average of 102 mm of rain was recorded over those three days in mid-September. Dr. Nautiyal noted a shift in rainfall timing, with rains now occurring suddenly and more frequently in September rather than June or July. This change is being studied at his institute to understand its impact on the central Himalayan region's increasing fragility.

Impact of Forest Fires and Local Ecology

Dr. Nautiyal pointed out that forest fires have also contributed to the rise in landslides this monsoon. These fires destroy herbs and grasses, weakening the soil layer and allowing water to flow unchecked, leading to landslides. He emphasised that fragmented monsoon rains are partly due to the deteriorating local ecology of the Himalayan region.

Despite these challenges, areas like Jaddhar forest in Garhwal and Shitalakhet forest in Kumaon have maintained their ecological balance due to dense forests. These regions experience early and heavy monsoon rains, thanks to effective local governance and community involvement in preserving their ecological health.

Collaborative Efforts for Sustainable Solutions

The National Mission for Sustainable Himalayan Ecosystem is actively working towards restoring local ecology in the Himalayan region. Dr. Nautiyal stressed that collaborative efforts from various institutes are necessary to address these environmental challenges effectively. He believes that relying on a single institute's efforts will not suffice.

Additionally, climate change has led many people to abandon agriculture due to crop damage in mountainous areas. Dr. Nautiyal called for a collective study on the adverse effects of weather on Himalayan agriculture, urging multiple agencies to collaborate for comprehensive research.

The ongoing changes in rainfall patterns and their impact on landslides highlight the need for coordinated efforts to address climate change's effects on Uttarakhand's environment. By understanding these dynamics better, stakeholders can develop strategies to mitigate risks and preserve the region's ecological balance.
