In recent years, urbanization has emerged as one of the major drivers of global environmental change, transforming mountain regions, particularly in developing countries where urbanization has been rapid but mostly unsystematic, unplanned, and unregulated. The Himalaya, a tectonically active, densely populated, and one of the world's most marginalized mountain regions, has experienced rapid urban growth over the last three decades. In this article, we will discuss Urbanization in the Himalayas which will be helpful for UPSC exam preparation.

How is Urbanization linked to Vulnerability?

Interlinkage of Urbanization and Climate Change

• Urbanization processes have created vulnerability and exposure, which, when combined with climate change hazards, has driven urban risk and impacts.
• Extreme heat and humidity will create potentially lethal climatic conditions.
• Cities in India will face increased heat stress, urban flooding, and other climate-related hazards such as cyclones.
• A quarter of Indians now live in cities; in the next 15 years, this figure is expected to rise to 40%.
• The primary driver of increased heat exposure in India is a combination of global warming and population growth in already-warm cities.

Consequences

• In urban areas, older adults, people with comorbidities, and people who do not have easy access to sanitary environments will be at a much higher risk.
• A higher urban population combined with high climate vulnerability in urban areas implies heat-induced labour productivity loss, resulting in economic consequences.
• Current adaptation measures primarily focus on quick fixes and disaster management, which must be replaced with long-term planning for resilient cities.
• Sea-level rise, increased tropical cyclone storm surge, and higher rainfall intensities will increase the likelihood of cities flooding.
• Coastal megacities (Mumbai, Chennai, Kolkata, and Visakhapatnam), smaller coastal towns and villages, and the Andaman and Nicobar Islands are all at risk of flooding.

Impact of Urbanization on the Himalayas

• The Himalayas' urbanization consists of sprawling small towns with populations under a lakh. Unplanned urbanization is altering land use and land cover significantly.
• Increased rainfall variability is one of the physical effects of climate change. Heavy rains are becoming more common, causing more landslides.
• Global warming has increased the average temperature in the Himalayas, causing glacier melt and a change in the region's hydrological regimes.
• Black carbon, a byproduct of stubble burning, brick kilns, and polluting industries, has also exacerbated the glacial decline.
• The majority of towns in the Himalayan region get their water from springs, ponds, and lakes.
• Urbanization in the Himalayas is reducing the cover of these water bodies, resulting in water insecurity in hill towns.

Solid Waste

• The continued expansion of urban settlements, and 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.
• Human-induced pollution, such as solid waste, untreated sewage, and local air pollution from vehicles, has been steadily increasing in the IHR in the absence of proper management practises and inadequate infrastructure.

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.
• Unplanned construction activities are known to cause large-scale land instabilities, the drying up of natural water sources, waste disposal issues, and changes in socio-cultural values.
• Deforestation activities - cutting in an area causes ecological damage and slope instability in adjacent areas.

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.
• Furthermore, the state government has taken a Cabinet decision to ban all plastics in the state since 2009.

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.
• The sweepers collect waste from each household and direct it to the compost pits for a small monthly fee.
• Apart from the residents, schools and hotel owners have offered the authorities their full cooperation in order to save the area's valuable eco-system.
• They can also generate income and employment by converting it to manure.

Conservation of Dal lake

• Dal Lake, a popular tourist destination in Jammu and Kashmir, is also notable for its 60,000-person settlement within the lake.
• The lake is in danger due to anthropogenic pressure and overall deterioration of the surrounding environment.
• The lake has been included in the MoEF, GOI lake conservation programme.
• The Lake and Waterways Development Authority (LAWDA), Srinagar, has taken up the initiative for lake conservation through education and mass awareness, in collaboration with the Centre for Environment Education (CEE) and other NGOs.
• The use of polythene carry bags has also been prohibited in the lake area.

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.
• The mission will last seven years, beginning in 2005-06 with 13 towns.

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 compost 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 practises, 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 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.

Environmental Issues in India

In India, factors such as rapid population growth, urbanization, industrialization, and poverty, among others, are to blame for environmental degradation. Some of the most serious environmental issues in India are:

• Deteriorating Air Quality Index
• Rampant Environmental Degradation
• Biodiversity loss
• Urbanization in the Himalayas
• Ecosystems' Loss of Resilience
• Lack of Waste Management
• Resource depletion (land, air, water)
• Growing Water Scarcity

Governmental Initiatives to Combat Environmental Degradation

While the cooperation of every citizen of the country is essential for environmental protection, governments have a significant role to play in assisting in the resolution of problems. The Indian government has taken numerous steps to protect the environment. Some of them are listed below:

• Swachh Bharat Mission
• Green Skill Development Program
• Namami Gange Programme
• Compensatory Afforestation Fund Act (CAMPA)
• National Mission for Green India
• National River Conservation Program
• Natural Resource and Ecosystem Conservation

Conclusion

Rapid population growth, poverty, urbanization, industrialization, and other factors are to blame for the rapid degradation of the environment in India. In the Himalayas, urban growth cannot be stopped or reduced, but it can be directed in a more sustainable direction through integrated urban-rural land use planning. Effective land use policies must be developed and implemented to protect and conserve forests, biodiversity, water resources, and agricultural land.
