Our Hills And Mountains Are Flowing Away.

I have been coming across those pictures frequently, observing the erosion, flooding, and accumulation of gravels in the river streams, which usually only occurs during the monsoon seasons. This time, I feel compelled to write something about it. Although I am not an expert or a technical person in this field, I maintain a deep concern for climate and environmental issues, as they affect every aspect of our lives.

While traveling from one place to another, I encountered a dry river stream and witnessed its impacts during the monsoon season. It was a sobering experience, realizing how close our hills and mountains are to collapse. The sound of rushing water mixed with rocks, soil, sand, and gravels was a clear indication of impending danger.

Through my observations, along with reading articles and news reports, I try to articulate my thoughts and concerns, hoping to contribute to the dialogue surrounding these pressing environmental challenges.

 

In the midst of the hottest discussions surrounding climate change, global warming, and human activities, particularly those of developed and developing nations, it's crucial to focus on the state of our hills and highlands. These areas are often overlooked, yet they play a vital role in our ecosystem and are vulnerable to various forms of degradation.

Research reveals that the rocks in these regions are geologically young and weak, rendering them prone to degradation, landslides, and soil erosion. The consequences of such degradation are becoming increasingly evident, especially during the rainy seasons. Rivers in hilly areas carry not just water, but also soil, stones, and gravel, a grim reminder of the impact of erosion.

The floods of recent years, such as the devastating flooding in Melamchi in 2021 and Mustang in 2023, serve as stark examples of the consequences of neglecting hillside erosion. These disasters, though visibly striking near human settlements, are just a fraction of the erosion-related incidents occurring across hill regions.

Addressing hill erosion requires urgent investigation and concerted action. While some efforts have been made, they remain insufficient in the face of the magnitude of the problem. Temporary solutions, such as localized projects, are not enough to tackle the broader issue. Further research is imperative to understand the complexities of erosion in these terrains and to devise sustainable solutions.

Various forms of degradation plague mountain and hill regions, including disintegration, slaking, and subaerial degradation. Of these, slaking, surface landslides, and erosion along gullies and riverbanks are particularly problematic. The fragile balance between erodibility and erosion resistance in these regions makes them susceptible to human-induced disturbances, such as deforestation and unsustainable construction practices.

Our mountains and hills are not just static formations; they are dynamic, tectonically active landscapes. The constant lateral pressure and disintegration they face result in unstable terrains and river channels. Yet, there exists a natural tendency for balance, even in the face of imbalance. Understanding and respecting this equilibrium is vital in managing the risks posed by landslides, erosion, and river dynamics.

At the end,  the erosion of our hills and mountains is not just an environmental concern; it is a societal imperative. We must prioritize research, sustainable development practices, and proactive measures to safeguard these critical landscapes for generations to come.
