Sustainable Cities and communities – The future essentials

Sustainable cities and communities are gaining popularity due to rapid urbanization, population growth, and pollution. They aim to achieve environmental, social, and economic sustainability for current populations without compromising the ability of future generations to do the same. According to the 2018 Revision of World Urbanization Prospects, 68% of the global population is projected to live in urban areas by 2050, with this figure expected to rise. In this blog, we will explore the concept of sustainable cities and society, examine a sustainable city model, and discuss their features, as well as the reasons for their growing prominence.

What are Sustainable Cities and Communities ?

Sustainable cities and communities are those that are dedicated to achieving environmental, social, and economic sustainability for existing populations. However, the concept doesn’t jeopardize the ability of future generations to experience the same. We will go through the definition of each of the terms.

• Sustainable Cities
• Sustainable communities

Sustainable city – Definition and Key features

A sustainable city balances environmental, social, and economic needs. This aims to provide residents with a high quality of life while safeguarding resources for future generations.

Key features of sustainable cities include efficient public transport, renewable energy sources, ample green spaces, and robust waste reduction programs. Generally, these cities prioritize economic opportunities alongside social equity. They focus on minimizing energy usage, conserving water, and optimizing food production. Additionally, they aim to drastically reduce waste and heat emissions while lowering carbon footprints through sustainable practices.

Urban planning integrates smart technology and innovative design to build resilient infrastructure. This basically ensures long-term environmental health, economic prosperity, and social well-being for all residents.

Sustainable community -Definition and Importance

Sustainable communities are essential for our future. Together, they ensure that we meet our needs today without compromising the ability of future generations to meet theirs. Here’s why they matter:

• Environmental Impact: Sustainable practices reduce waste and preserve natural resources. Consequently, they contribute to mitigating climate change.
• Public Health: Clean air, water, and energy sources improve community well-being. Additionally, they reduce healthcare costs and enhance quality of life.

• Renewable Energy: Using solar and wind power lowers greenhouse gas emissions. Consequently, it supports energy independence and reduces reliance on fossil fuels.
• Local Economy: Supporting local businesses and agriculture boosts economic resilience. Furthermore, it fosters community pride and enhances economic diversity.
• Social Equity: Access to affordable housing, healthcare, and education for all ensures fairness and opportunity. Additionally, it reduces disparities and promotes inclusive growth.
• Resilience: Collaborative efforts build strong communities prepared for challenges. Therefore, they enhance disaster preparedness and community cohesion.

“Together, these elements create neighborhoods that are not only environmentally friendly but also socially and economically robust, ensuring a sustainable and equitable future.”

Now that we’ve explored sustainable cities and communities, let’s delve into why they are essential.

Importance of Sustainable City model

According to the UN Environment Programme, contemporary cities grapple with several critical challenges. Basically, these include

• Environmental degradation
• Traffic congestion
• Insufficient urban infrastructure
• Shortage of basic services such as water supply and sanitation
• Waste management

Despite covering a mere 3% of the Earth’s land, cities consume 60 to 80% of global energy and produce over 70% of carbon emissions. Consequently, prioritizing the development of clean, resilient, and sustainable cities stands as a paramount goal within the UN Sustainable Development Agenda.

By addressing these challenges through innovative urban planning, renewable energy adoption, and enhanced infrastructure, cities can mitigate their environmental footprint while improving the quality of life for residents. This approach not only promotes a sustainable city model but also contributes to global efforts in combating climate change and fostering equitable economic growth.

Urban sustainability practices – Benefits

• A sustainable city model encourages economic development and meets the basic needs of its residents while also ensuring that all residents live in safe and healthy environments.
• A sustainable city model provides a long-term way of life in all four domains: ecology, economics, politics, and culture and can solve all the problems faced by modern-day cities.
•  Richard Florida, an urban studies theorist, focuses on the social effect of sustainable cities, stating that cities should foster a great people environment that appeals to individuals and families of all sorts, rather than just a competitive business climate.
• As a result, a transition to a sustainable urban living will provide a venue for social interaction and create conditions conducive to human flourishing.
• Sustainable city model will also encourage the use of public transportation, walkability, and biking, both of which would improve both residents’ health and the environment.

Let’s go for a trip through a sustainable city and learn its features.

Features of Sustainable Cities

“Sustainable urban planning focuses on principles that enhance livability and resilience in cities:

• Urban Agriculture and Urban Forests
• Sustainable Transportation
• Energy Conservation
• Green Buildings
• Effective Waste Management Strategies
• Recycling and Circular Economy Practices
• Mixed Land Use
• Community Engagement

These principles aim to create cities that are environmentally sustainable, socially inclusive, and economically vibrant, meeting the needs of current and future generations.”

Urban Agriculture and Urban Forests

Urban agriculture is the method of growing and distributing food, as well as raising livestock, in and around a city or urban areas. It strongly links and depends on the urban ecosystem in the following ways:

• Use of urban residents as key workers 
• Use of typical urban resources (such as organic waste as compost or urban wastewater for irrigation)
• Direct links with urban consumers
• Direct impacts on urban ecology (both positive and negative)
• Being a part of the urban food system
• Being influenced by urban policies and plans are all examples of such linkages.

Let’s have a look at how urban farming contributes in making a city sustai

Contribution of Urban Farming in a Sustainable City

• Energy used to transport food is decreased when urban agriculture can provide cities with locally grown food.
• Urban agriculture’s energy-efficient design will minimise each city’s carbon footprint thereby reducing the amount of transportation required to deliver goods to consumers. 
• Mostly, such areas can serve as carbon sinks, absorbing some of the carbon that urban areas naturally accumulate. 
• Produce grown in urban gardens is often thought to be more flavorful and appealing than produce purchased in stores. 
• Increased consumption of fruits and vegetables is linked to a lower risk of disease, and urban agriculture. Generally, this can be a cost-effective way to provide residents with fresh produce in urban areas.

Sustainable Transportation

Sustainable transportation aims to create a more environmentally responsible and socially equitable urban core. This altogether reduces a city’s dependence and use of greenhouse gases by combining

• Eco-friendly urban development
• Low-emission cars
• Residential proximity

Basically, transportation networks currently account for about a quarter of global energy consumption and CO2 emissions. Since transportation services have such a large effect on a city’s energy use, planning experts have placed a greater focus on sustainable transportation in the last decade. Some of the key areas of focus are:

Car-free Cities

• Car-free cities or cities with significant pedestrian areas are often included in the design of a sustainable city.
• The car-free idea is often considered an important part of the design of a sustainable city.
• Following the COVID-19 lockdown, large areas of London will be made car-free to enable people to walk and cycle safely.

Urban Proximity

• Urban proximity necessitates the construction and expansion of cities with sufficient population and landmark density so that destinations can be reached in less time.
• This reduced time in transit reduces fuel consumption and makes alternative modes of transportation, such as biking and walking, more available.

Energy Conservation

Sustainable cities prioritise the use of renewable energy sources to reduce and manage emissions. Renewable energy is the energy obtained from sources that are naturally replenished on a human time scale such as wind turbines, solar panels, or bio-gas generated from sewage.

Sustainable cities  minimise the need for air conditioning (a huge energy demand) by:

• Planting trees 
• Lightening surface colours
• Using natural ventilation systems 
• Creating green spaces covering at least 20% of the city’s surface 

• These interventions combat the “heat island effect” caused by an excess of tarmac and asphalt, which can make urban areas several degrees warmer than rural areas—up to six degrees Celsius in the evening. 

• Green roofs help to reduce the urban heat island effect by altering the surface energy balance. However, Air quality, environment, and water runoff are all benefitted from incorporating eco-roofs or green roofs in sustainable cities.
• Sustainable cities also adopt xeriscaping, rainwater harvesting, hydroponics etc for water conservation. 

Green Buildings

Sustainable Cities promote LEED-certified green buildings. LEED, or Leadership in Energy and Environmental Design, is a green building certification scheme that is used all over the world. A building may have a variety of features that make it “green.” Let’s have a look at some of them:

• Power, water, and other resources are used more efficiently.
• Use of renewable energy sources.
• Steps to reduce pollution and waste, as well as the facilitation of re-use and recycling.
• Satisfactory indoor air quality.
• Non-toxic, ethical, and long-lasting products are used.

Effective Waste Management Strategies

Effective waste management aims to reduce environmental impact and conserve resources. Key strategies include:

• Recycling: Convert waste into reusable materials.
• Composting: Turn organic waste into valuable soil amendments.
• Circular Economy Practices: Design products for durability, reuse, and recycling.
• Waste Segregation: Ensure hazardous and non-recyclable waste is disposed of safely.
• Public Awareness and Education: Promote sustainable waste practices through campaigns.

Recycling and Circular Economy Practices

Recycling

• Material Recovery: Collect and process waste materials to create new products, thereby reducing the need for virgin resources.
• Waste Reduction: Decrease the amount of waste sent to landfills by reusing materials.
• Energy Savings: Manufacturing products from recycled materials often requires less energy than producing them from new materials.
• Environmental Protection: Reduces pollution and conserves natural resources by limiting the extraction and processing of raw materials.

Circular Economy Practices

• Product Design: Create products with longer life spans, easy repairability, and recyclability to minimize waste.
• Resource Efficiency: Maximize the use of resources by keeping them in use for as long as possible through reuse, remanufacturing, and recycling.
• Waste as a Resource: Treat waste as a resource to be recovered and reused, rather than discarded.
• Sustainable Business Models: Implement models like leasing, sharing, and product-as-a-service to reduce the need for new products and encourage efficient resource use.
• Lifecycle Thinking: Consider the environmental impact of products throughout their entire lifecycle, from production to disposal.
