The Indian Himalayan Region (IHR), occupies a strategic position along the entire northern and northeastern boundary of the country and administratively covers ten states in their entirety (Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura, Meghalaya) and two states partially (the hill districts of Assam and West Bengal), has wide-ranging ecological and socioeconomic significance. In this article, we will discuss Environmental Issues in Indian Himalayan Region which will be helpful for UPSC exam preparation.

Indian Himalayan Region Service

• Aside from numerous goods, IHR provides a plethora of services not only to Himalayan residents but also to people living far beyond its borders.
• Among other things, the region's large area under permanent snow cover and glaciers forms a unique water reservoir that feeds several important perennial rivers.
• With its vast green cover, IHR also serves as a massive “carbon sink.”
• IHR is also a significant part of the identified Himalayan Biodiversity Global Hotspot.

Role of Indian Himalayan Region in Indian Climate

• The region is experiencing environmental issues as a result of a variety of factors, including the stress caused by anthropogenic activities.
• Even geologically, the Himalayan ecosystem is among the most vulnerable. As a result, the environmental issues confronting the IHR are critical.
• Sustainable management of the Himalayan ecosystem is critical not only for preserving its pristine beauty and spectacular landscapes, but also for ensuring the Indian subcontinent's ecological security.

Urbanization in the Himalayas

• Uncontrolled demand-driven economic growth has resulted in haphazard urbanization, environmental degradation, and increased risks and vulnerabilities, seriously jeopardising the unique values of Himalayan ecosystems.
• In addition to a focus on economic growth, the roadmap for sustainable development of the Indian Himalayas must be in line with the relevant Sustainable Development Goals (SDGs).
• As a result, development in the Himalayas must be fully integrated into the region's environmental, sociocultural, and sacred tenets.

Impact of Urbanization

Solid Waste

The continued expansion of urban settlements, influx of visitors, trekkers, and mountaineers in the Himalayan region has begun to pose high biotic pressure and concomitant indiscriminate solid waste dumping. As a result, the IHR suffers.

Town-Planning

Rapid unplanned growth of hill towns, construction activities without a proper plan, general noncompliance with prescribed norms and guidelines, and indiscriminate use of land for commercial outfits/tourist resorts have severely and adversely affected the Himalayas' fragile ecosystem.

Initiatives of the Indian Himalayan Region

Ban on Plastic in HP

• The Himachal Pradesh Non-Biodegradable Garbage (Control) Act, 1995 was enacted by the state government to prohibit the disposal of non-biodegradable garbage in public drains and roads.
• The minimum thickness of plastic carry bags was then increased to 70 microns of virgin material, exceeding the 20 micron thickness recommended by Central Rules.

Participatory Conservation of Lakes in the Region

• The Naini Lake serves as the sole source of drinking water for Nainital, a popular tourist destination in Uttarakhand.
• The increasing influx of tourists, as well as urban waste that finds its way into the lake, is having a negative impact on water quality.
• To protect the water body, residents have implemented a scientific garbage disposal system, known as 'Mission Butterfly' by the Nainital Lake Conservation Project.

Assam Hill Land and Ecological Sites Act, 2006

• The Assam Hill Land and Ecological Sites (Protection and Management) Act, 2006, was enacted to prevent indiscriminate hill cutting and filling of water bodies in urban areas, which had resulted in serious ecological problems in places like Guwahati.
• The state government can bring any hill under its protection under the Act.

Jawaharlal Nehru National Urban Renewal Mission

• The goal is to encourage reforms and accelerate the planned development of identified cities.
• The emphasis will be on efficiency in urban infrastructure and service delivery mechanisms, community participation, and the accountability of ULBs/parastatal agencies to citizens."

Recommendations / Solutions for Solid Waste Management in IHR

• The current state of "development" is unsustainable. An integrated approach is thus required to protect the environment while also achieving the necessary economic development.
• Advance planning based on timely and reliable data has become critical for the long-term growth of hill towns.
• Regulations prohibit the indiscriminate disposal of garbage, particularly non-biodegradable waste.
• Preventive and management measures for solid waste management at the point of origin.
• Documentation of the varying composition of waste from hill towns to expedition summits.
• Promotion of techniques such as the conversion of biodegradable waste into biocompost or vermicompost instead of landfilling, open dumping, or burning.
• The four 'R's principles' are as follows:
  • refuse waste-prone commodities,
  • reuse discarded commodities for other purposes,
  • reduce through segregation into categories—biodegradable and non-biodegradable at the household/individual level, and
  • recycle once fully used or completely unusable commodities/items.
• Good quality potable water is available at various locations in hill towns for people to fill their bottles for a fee.
• Increased stakeholder awareness and capacity.
• Best international experiences and practices for environmental preservation and litter prevention in eco-sensitive areas should be studied and appropriately adopted.
• There is a need for assistance and innovative thinking in a variety of areas, including traditional architectural practices, local water management, and various sewage and garbage disposal systems.
• There is a need to encourage residents to participate in the transition to a more scientific waste disposal system.

Recommendations / Solutions - Hill Town Planning and Architectural Norms

• Habitat fragmentation in hill areas should be avoided.
• Specific areas for rural/urban development should be identified.
• There should be no construction in hazard zones or on spring lines or first-order streams.
• Architectural and aesthetic standards for building construction in mountain/hill areas should be strictly enforced.
• Deforestation activities must be avoided by taking appropriate precautions.
• An integrated development plan can be created by taking into account environmental and other relevant factors.
• All construction in seismically active areas, such as the Himalayas, should include earthquake-resistant features.
• Buildings should be built using location-specific technologies.
• "Green roads" with channels for collecting water for irrigation should be made a construction standard.

Tourism in India

Pilgrimage Tourism in Sensitive Areas

• Since time immemorial, the Himalayas have been known as a pilgrimage destination and a home for saints.
• For example, Badrinath, Kedarnath, Gangotri-Yamunotri, and Hemkund Sahib in Uttarakhand, Manimahesh, Jwala Devi, Chintpurni, Naina Devi in Himachal Pradesh, Vaishnav Devi and Amarnath in Jammu & Kashmir, and Khecheopalri and other sacred lakes in Sikkim are all important pilgrimage sites.
• Unfortunately, most of these locations lack adequate transportation, lodging, waste disposal, and other amenities for the ever-increasing number of pilgrims who visit them each year.
• Furthermore, there is a severe lack of regulatory mechanisms for infrastructure creation, management, and controlling tourist inflow to such sites.
• As a result, the sensitive ecosystems and cultural values of these areas are under stress far beyond their carrying capacities.

Impact of Commercial Tourism on the Environment

• Because of the Himalayas' high biodiversity and environmental sensitivity, the impacts of tourism on mountain ecosystems and biological resources are of great concern.
• Cultural identities and diversity in mountain regions are also threatened by the economic, social, and environmental forces associated with mountain tourism.
• In this context, community-based ecotourism emerges as one of the more sustainable alternatives to commercial tourism in already oversaturated hill towns such as Nainital, Mussoorie, Shimla, KulluManali, Gangtok, and others.

Initiatives to Boost Tourism in India

Harnessing Religious Sentiments for Conservation

• There is enormous potential for harnessing tourist religious sentiments in the context of conservation and sustainable management of natural resources in eco-sensitive Himalayan areas.
• This can be accomplished by:
  • encouraging them to engage in participatory plantation for the rehabilitation of degraded areas (e.g., Badrivan initiative of GBPIHED in Uttarakhand).
  • Promoting the concept of eco-cultural landscapes (e.g., Demazong – Buddhist landscape, Sikkim, and Apatani eco-cultural landscape, Arunachal Pradesh). Both landscapes are highly evolved, with high levels of economic and ecological efficiency.
  • Involving them in the maintenance and strengthening of sacred groves/landscapes (e.g., Sacred Groves of Meghalaya: The tribal communities - Khasis, Garos, and Jaintias - have a tradition of environmental conservation based on religious beliefs and customary law and are protected from any product extraction.)

Ladakh Himalayan Homestays

• The Himalayan Homestays programme promotes conservation-based community-managed tourism development in remote settlements by gradually increasing local capacity and ownership.
• It stands out as an example of how to be sensitive to both host and visitor expectations without compromising the aspirations of host communities, while also attempting to balance these aspects with conservation of the area's unique cultural and natural heritage.

Adventure Tourism

• Through community involvement, enormous opportunities for adventure and ecotourism in the Himalayan region could be realised.
• For example, Annapurna Conservation Area project, Nepal; Nanda Devi Biosphere Reserve ecotourism approach, Uttarakhand.

Tourism Art and Culture

• Linking tourism to initiatives like Rural Business Hubs (RBH), which promote quality rural products like handloom, handicrafts, agro products, herbal products, bio-fuel, and so on, as introduced in the North East region, may be considered as another aspect of promoting eco-tourism in the IHR.

Regulated Entry

• The Uttarakhand government has limited the number of tourists allowed to visit the Gangotri area to 150 per day.

Solutions of Tourism in India

• Pilgrimage tourism in the Himalayas necessitates both development and regulation in order to reduce congestion and pollution.
• Pilgrimages require the development of accommodation and road transportation infrastructure.
• In the Indian Himalayan Region, pilgrimage tourism is a type of "economy class" tourism. Appropriate accommodation and other facilities must be made available.
• Garbage disposal and management should be available at all existing sites.
• A list of historical, sensitive, and sacred sites, including sacred groves, should be created, and their vulnerability assessed.
• Vehicle access to such incomparable value sites must be restricted beyond a certain zone.

Conclusion

Environmental insecurity has been responsible for guiding and directing civilizations in the Himalayas for millennia. Since antiquity, humans and the Himalayan environment have had a close relationship. However, things have recently deteriorated in this vulnerable resource zone. In recent times, we have sought to adapt the Himalayan environment to our needs, thereby allowing for environmental possibilities in this otherwise vulnerable region. It has caused environmental imbalances and has exacerbated natural processes. This is a very serious issue with far-reaching implications for the future security of the Himalayan environment and its inhabitants.

GS Mains Questions and Model Answers

Q1: Discuss the impact of climate change on the glaciers of the Indian Himalayan region and its implications on water resources.

Answer: Climate change is having a significant impact on the Himalayan glaciers, leading to their accelerated retreat. This results in several consequences:

• Reduced Freshwater Availability: The glaciers serve as a crucial source of water for rivers such as the Ganges and Brahmaputra. As glaciers shrink, the amount of meltwater available decreases, which leads to water scarcity in downstream areas.
• Glacial Lake Outburst Floods (GLOFs): The retreat of glaciers has created glacial lakes, which are at risk of bursting. If these lakes overflow, they can cause catastrophic flooding downstream, leading to the loss of lives and infrastructure.
• Disruption of Seasonal Flow: The seasonal flow of rivers is disrupted as the glacial meltwater decreases, which impacts agriculture, power generation, and drinking water supply in the region.
• Long-Term Water Stress: As glaciers continue to recede, future generations may face even more severe water shortages, which could strain agriculture and human settlements.

Q2: How does deforestation contribute to environmental degradation in the Indian Himalayan region?

Answer: Deforestation is a key driver of environmental degradation in the Indian Himalayan region. The removal of trees and forests leads to:

• Soil Erosion: Without the stabilizing effect of tree roots, the soil becomes vulnerable to erosion, particularly during the monsoon season, when heavy rains wash away topsoil. This reduces soil fertility and makes farming more difficult.
• Loss of Biodiversity: The destruction of forests eliminates habitats for many species, leading to a loss of biodiversity. This also affects the region’s ecosystem services, including water filtration and climate regulation.
• Increased Flooding: Deforestation reduces the land's ability to absorb and store rainwater, leading to increased surface runoff and flash floods.
• Climate Change: Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere. Their destruction contributes to increased levels of greenhouse gases, exacerbating climate change.

Q3: Evaluate the role of the Indian government and local communities in addressing environmental issues in the Himalayan region.

Answer: The Indian government, in partnership with local communities, plays a vital role in addressing the environmental challenges in the Himalayan region:

• Government Efforts: The government has implemented policies like the National Mission for Sustaining the Himalayan Ecosystem, which aims to address climate change impacts, conserve biodiversity, and promote sustainable land use. Initiatives like the Green India Mission and afforestation programs help restore degraded areas and reduce soil erosion.
• Local Community Participation: Local communities, who are directly impacted by environmental changes, play a crucial role in conservation efforts. Traditional knowledge of sustainable farming, forestry, and water management is valuable in the eco-restoration process. Community-led initiatives, such as community-based forest management and eco-tourism, can significantly reduce deforestation and promote conservation.
• Climate Adaptation: Both government and local communities are working together on climate adaptation strategies, including improving disaster preparedness, rainwater harvesting, and promoting sustainable livelihoods to mitigate the impacts of environmental degradation.

Previous Year Questions on  Indian Himalayan Region

1. UPSC CSE 2020

Question: "How does the melting of glaciers in the Himalayan region affect the water resources in India?"

Answer: The melting of glaciers in the Himalayan region significantly affects India’s water resources. The retreat of glaciers reduces the flow of water into major rivers like the Ganges, Brahmaputra, and Indus, which depend on glacial meltwater. This causes water shortages in the region, particularly affecting agriculture, drinking water, and hydropower generation. In the long term, the loss of glaciers will further strain water resources, creating challenges for millions of people who depend on these rivers for their livelihood.

2. UPSC CSE 2020

Question: "Discuss the impact of soil erosion on agriculture in the Indian Himalayan region."

Answer: Soil erosion in the Indian Himalayan region is a major environmental issue that impacts agriculture. The loss of topsoil due to erosion makes the land less fertile and less capable of supporting crops, which directly affects the food security of local communities. The increased frequency of landslides and floods due to soil erosion also disrupts agricultural activities, causing further economic hardship. Additionally, the reduction in soil quality limits agricultural productivity, forcing communities to abandon their traditional farming methods and shift to unsustainable practices.
