Urban Heat Island

The Urban Heat Island (UHI) effect is a critical urban environmental issue, exacerbating the impacts of global warming and climate change on urban populations. It not only poses significant health risks, particularly to vulnerable communities, but also increases energy consumption due to higher cooling demands, contributing to greater carbon emissions. Moreover, the UHI effect influences local ecosystems, affecting biodiversity and altering natural processes. This article delves into various definitions of the UHI effect, elucidating its complex nature and the range of factors that contribute to its intensity.

 


The Urban Heat Island (UHI) effect is a climatic phenomenon observed in urban areas, where temperatures are significantly higher than in surrounding rural areas. This discrepancy in temperature is attributed to human activities and urban development, which alter land surfaces and environments. The term “Urban Heat Island” originates from the visual representation of temperature distribution maps, where urban areas are depicted as “islands” of higher temperatures amidst cooler rural “seas.” First identified in the early 19th century by Luke Howard, the UHI effect has grown in relevance and urgency with the accelerating pace of global urbanization and climate change. It matters profoundly in today’s world as it exacerbates the impacts of global warming in densely populated areas, affecting millions of lives by increasing heat stress, energy consumption, and air pollution levels.

Indore to set up India’s First PPP Green Waste Processing Plant

 Under the Swachh Bharat Mission-Urban, Indore is poised to achieve a major milestone with the launch of India’s first green waste processing plant, developed through a Public-Private Partnership (PPP) model.

Indore is all set to make a significant leap towards environmental sustainability with the launch of India’s first PPP-model based green waste processing plant under the Swachh Bharat Mission-Urban. This groundbreaking initiative, aims to revolutionize the city’s waste management system by converting green waste into valuable resources. This project underscores the city’s commitment to innovation and sustainability in tackling urban waste challenges.

The facility will not only process green waste but also generate revenue, with the Indore Municipal Corporation (IMC) earning approx. Rs 3,000 per tonne in royalty for supplying wood and branches. Built on a 55,000 square feet land in Bicholi Hapsi, the plant will recycle wood and branches to produce wooden pellets, serving as an alternative to coal and promoting energy conservation.

Branches of large trees will be redirected to the Green Waste Processing Plant at City Forest, where they will be repurposed into valuable products. In addition, green waste generated from the premises of major institutions will be directly collected and sent to the facility, with a fixed fee structure in place. Every day, the bustling city of Indore generates approximately 30 tons of green waste—wood, branches, leaves, and flowers. As the seasons change, especially during autumn, this volume can soar to 60 to 70 tons.

Partnering with the Indore Municipal Corporation, Astronomical Industries Private Limited embarked on an ambitious initiative to transform the city’s green waste into something both sustainable and valuable—a fine sawdust that could be used across a wide array of industries. With a detailed plan in place, the idea is to dry the green waste over a span of three to four months. During this time, the moisture content would decrease by 90%, preparing the material for the next stage. As the months pass by, the green waste, once damp and cumbersome, would become light and brittle, almost ready for transformation. cutting edge machines will then help to break it down into fine dust particles - saw dust. Once an unremarkable byproduct of timber mills, now has a second life, contributing to a sustainable, circular economy.

The saw dust can be transformed into eco-friendly fuel, providing a cleaner alternative to traditional burning methods. It can be used to craft durable packing materials that reduce the need for plastic. Furniture manufacturers find it useful as a composite material, lending strength to products like chairs and tables. Fertilizers made from the sawdust enriches the soil, helping farmers grow healthier crops. And in the food industry, the sawdust can be moulded into disposable plates, offering a biodegradable alternative to plastic and Styrofoam.

Under the Swachh Bharat Mission, the IMC will play a pivotal role by providing and transporting land and green waste to the plant. Meanwhile, the private company will take on the responsibility of setting up the remaining infrastructure, including sheds, electricity, and water facilities. The private firm will also oversee the complete installation and operation of the plant, ensuring its smooth functioning from start to finish.

Other private firms have set up the Meghdoot and sub-grade plants, spanning an area of 10,000 to 15,000 square feet in Sirpur. These facilities are dedicated to processing garden waste, such as leaves and small twigs, sourced from the municipal corporation. As part of this initiative, composting is also being carried out in specially designed compost pits located within the municipal gardens, further enhancing waste management efforts. Wooden pellets, produced from green waste, are utilized across various industries, including the National Thermal Power Corporation (NTPC), where they serve as an eco-friendly alternative for energy production and other applications.

The goal of this initiative is to efficiently manage green waste, promote environmental sustainability, and create additional revenue streams for the Municipal Corporation. It also plays a crucial role in controlling the Air Quality Index (AQI). By improving waste management practices, this initiative will enhance hygiene, reduce pollution, and curb the unnecessary burning of waste, contributing to a cleaner and healthier environment.

The project will also provide an alternative source of coal, contributing to AQI control while offering an effective solution for cleanliness and environmental protection. This initiative aligns with the vision of Garbage-Free Cities under the Swachh Bharat Mission-Urban, advancing efforts toward a cleaner, greener, and more sustainable urban environment.

FINANCIAL ASSISTANCE AND REGULATORY FRAMEWOR UNDER ARHCs SCHEME

 Ministry of Housing and Urban Affairs (MoHUA) launched Affordable Rental Housing Complexes (ARHCs) as a sub-scheme of Pradhan Mantri Awas Yojana - Urban (PMAY-U) to provide dignified living to urban migrants/poor near their workplace. This scheme is implemented through two models:

  1. Model-1: Utilizing existing Government funded vacant houses constructed under Jawaharlal Nehru National Urban Renewal Mission (JNNURM) and Rajiv Awas Yojana (RAY) to convert into ARHCs through Public Private Partnership (PPP) or by Public Agencies,
  2. Model-2: Construction, Operation & Maintenance of ARHCs by Public/Private Entities on their own available vacant land.

Beneficiaries of ARHCs are urban migrants/poor from Economically Weaker Section (EWS)/Low Income Group (LIG). They include labour, urban poor (street vendors, rickshaw pullers, other service providers etc.), industrial workers, and migrants working with market/trade associations, educational/health institutions, hospitality sector, long term tourists/visitors, students or any other persons of such category.

Under Model-1, so far, 5,648 existing Government funded vacant houses have been converted into ARHCs in different States/Union Territories (UTs). Under Model-2, MoHUA has approved proposals for 82,273 new ARHC units in 7 States, of which 35,425 have been completed and remaining are under different stages of initiation/construction. These ARHCs provide dignified living with all civic amenities to the eligible beneficiaries at an affordable rate.  A total of ₹173.89 crore of Technology Innovation Grant (TIG) has been sanctioned, of which ₹83.26 crore has been released under ARHCs.

As per scheme guidelines, the initial affordable rent of ARHCs is fixed by the local authority based on a local survey. Subsequently, rent is enhanced biennially by 8%, subject to a maximum increase of 20% in aggregate, over a period of 5 years, effective from the date of signing the contract. The same mechanism is followed over the entire concession period i.e. 25 years.

As per the operational guidelines of ARHCs, various benefits/incentives were proposed by the Government to encourage proactive participation of Public/Private Entities in the construction and management of ARHCs. The operation guidelines are available at https://arhc.mohua.gov.in/filesUpload/Operational-Guidelines-of-ARHCs.pdf.

So far, the Ministry has not conducted any assessment of ARHCs. However, based on the learning from the experiences of 9 years implementation of PMAY-U, MoHUA has revamped the scheme and launched PMAY-U 2.0 ‘Housing for All’ Mission with effect from 01.09.2024 for implementation in urban areas across the country to construct, purchase and rent a house by 1 crore additional eligible beneficiaries at affordable cost through four verticals i.e., Beneficiary Led Construction (BLC), Affordable Housing in Partnership (AHP), Affordable Rental Housing (ARH) and Interest Subsidy Scheme (ISS). ARH vertical of PMAY-U 2.0 aims to construct rental housing projects for EWS/LIG beneficiaries including migrant workers and other poor who do not want to own a house but require housing for short term basis. The scheme guidelines of PMAY-U 2.0 are available at https://pmay-urban.gov.in/uploads/guidelines/Operational-Guidelines-of-PMAY-U-2.pdf.

UPGRADATION OF STPs

 Atal Mission for Rejuvenation and Urban Transformation (AMRUT) was launched on 25 June 2015 in selected 500 cities (485 cities including 15 merged cities) and towns across the country. The Mission focuses on development of basic infrastructure, in the selected cities and towns, in the sectors of water supply; sewerage and septage management; etc.  Further, AMRUT 2.0 was launched on 01 October 2021 in all Urban Local Bodies (ULBs)/ cities, enabling the cities to become 'self-reliant' and 'water secure'. Providing universal coverage of sewerage and septage management in 500 AMRUT cities is one of the major focus areas of AMRUT 2.0.

Under AMRUT, 890 sewerage/ septage management projects worth ₹34,505 crore have been grounded through which 4,447 Million Litre per Day (MLD) sewage treatment capacity (new/augmented) has been created of which 1,437 MLD capacity has been developed for recycle/reuse. 

Under AMRUT 2.0, 592 sewerage/septage projects worth ₹67,607.67 crore have been approved by Ministry of Housing and Urban Affairs (MoHUA) so far. Approved projects cover 6,739 MLD sewage treatment capacity (new/augmentation) of which 2,093 MLD sewage treatment capacity is for recycle/reuse. 

MoHUA has also launched "Jal Hi AMRIT" initiative under AMRUT 2.0 reforms, which aims to incentivize States and Union Territories (UTs) to efficiently manage sewage treatment plants for recyclable treated water meeting environmental standards on sustained basis. The focus of this initiative is to build capacity and incentivizing qualitative improvements in the treated discharge effluent. This initiative is targeted to create opportunities for suitable reuse of water, contributing to the overall goal of water security through increasing water availability under the Mission.
