Climate Change Impact on Nepal Himalayas

Climate change has impacted many countries, mainly small landlocked countries like Nepal. Nepal is a country in the Himalayas, and many trekkers visit the country for trekking and expeditions. However, not many people’s climate change impact on Nepal’s Himalayas is enormous, which we will discuss in this blog.

Nepalese Himalayas are an example of stunning, beautiful adventure and cultural diversity, but lately, they have faced the harsh results of climate change. Climate change’s noticeable impacts may include melting glaciers, uncommon winds, heavy falls, floods, and landslides. Due to climate change, the weather changes constantly, and its unpredictable patterns change the ecosystem rapidly.

So, let’s get into detail on how climate change impacts on Nepal Himalayas.

Impact of Climate Change on Nepalese Himalayas

Melting of Glaciers:

One of the most common impacts of climate change on the Nepalese Himalayas is rapidly melting glaciers. In the Himalayas, various glacial moraines are floating around, and when they melt, the water mixes up with the river, which becomes the source of fresh water for tons of people and many villages. However, lately, the rate of glacial melting has been alarming, which has led to the formation of several glacial lakes. In some conditions, outbursts and floods damage properties and take many lives in Nepal. It has significantly disturbed the natural water cycle of the Himalayas. It has been the primary cause of the rising sea level, which creates a considerable risk of drowning the vast land masses.

Erratic Rainfall Patterns:

Climate change is the primary reason for the change and disturbance patterns in the Himalayan region of Nepal. The erratic rainfalls where it continuously rains for one to two months, followed by long dry spells. The intense rainfall and the drought make agriculture and water management more challenging. The farmers also face more challenges as they can’t appropriately plan and harvest their crops in the adequate seasons.

Increased Floods:

Due to the extreme climate conditions, weather events like heavy rainfall, droughts, and hailstones are not regular. The extreme melting of ice raises the water level, which causes the rise of sea levels. When the water melts from glaciers mixed with rivers, lakes, or ponds, the chance of floods increases. The outburst of floods can cause significant damage to people’s lives and property.

Threats to Hydropower

Nepal relies heavily on hydropower for electricity and business with other countries. Due to efficient hydropower management, Nepal is not suffering from Loadshedding like before. Furthermore, Nepal sells its generated electricity to other countries like India, Pakistan, and Bangladesh. However, increased glacial melt and flooding cause floods to strike electric turbines at high speeds, which may cause malfunction. The cost of replacing or fixing the hydropower is relatively high.

Impact on Regular Livelihood

Agriculture, Tourism, and Hydropower are the most common activities that Nepalese families depend upon. However, the increased glacial level, the rise of floods and landslides, and damage in the agriculture and hydropower sectors due to climate changes impact the day-to-day lives of the local families. These sectors are where ordinary people earn their income, so the impact on them may cause a rise in unemployment and poverty levels.

Food Insecurity:

Farming is essential in the Nepal Himalayas, but the weather is changing and making it hard for farmers to grow food. This means that people might not have enough to eat. We must find new ways to grow food and try growing different crops to help with these problems. The changing weather is also affecting people’s jobs. For example, the tourism industry, which is a significant way people make money, is at risk because of the weather and other changes. Jobs like herding animals and farming are also getting more challenging, so people are looking for new ways to make money.

Health Risks:

Increasing temperatures in the Nepal Himalayas can lead to heat-related illnesses, and changes in rainfall patterns can raise the risk of waterborne diseases. When natural disasters force people to leave their homes, crowded temporary shelters can make spreading diseases easier.

Infrastructure Vulnerability:

The Nepal Himalayas’ infrastructure, including roads, bridges, and hydropower projects, is susceptible to damage from extreme weather events, landslides, and glacial lake outburst floods. Repeated infrastructure damage hampers development efforts and poses a significant financial burden for the government.

Indigenous and Marginalized Communities:

Indigenous and marginalized communities in the Nepal Himalayas are disproportionately affected by climate change. They often lack the resources and capacity to adapt to these changes, making them highly vulnerable to food and water insecurity, displacement, and loss of traditional knowledge and practices.

Mitigation and Adaptation Strategies:

Addressing the climate change impact in the Nepal Himalayas requires a multifaceted approach:

Reducing Emissions: Nepal is a relatively low emitter of greenhouse gases, but efforts to reduce emissions from sectors like energy, transportation, and agriculture can contribute to global climate mitigation.

Renewable Energy: Developing and promoting renewable energy sources such as hydropower and solar can reduce reliance on fossil fuels and provide a sustainable energy supply.

Glacial Lake Management: Implementing early warning systems and engineering interventions to manage glacial lakes can reduce the risk of glacial lake outburst floods.

Water Resource Management: Implementing efficient management practices can help address water scarcity issues and reduce conflicts over water resources.

Agricultural Adaptation: Promoting climate-resilient farming practices, crop diversification, and improved irrigation systems can enhance food security and livelihoods.

Biodiversity Conservation: Protecting and expanding protected areas can help safeguard critical habitats and support species’ adaptation to changing conditions.

Community-Based Adaptation: Empowering local communities through capacity building and providing access to resources and information can enhance their resilience to climate change impacts.

Disaster Preparedness: Developing and implementing disaster preparedness and response plans can reduce the loss of life and property during extreme weather events.

Education and Awareness: Raising awareness about climate change and its impacts is crucial for promoting sustainable practices and encouraging individuals and communities to take action.

Conclusion

Hence, the Nepalese Himalayas are greatly affected by the adverse effects of climate change, such as glacial melts, extreme rainfall patterns, extreme weather changes, effects on agriculture and hydropower, impact on water and food scarcity, etc. Despite being among the most severe subjects in modern times, climate change still hasn’t received the attention it needs.

The impact of climate change is essential, but it is also only in its initial stage, and if not carefully managed, it will be detrimental to our future generations. The countries’ governments need to organize a coordinated effort to tackle the challenge and find new ideas to combat this issue sooner rather than later.
