Sustainable Cities
The world is becoming increasingly urbanized. Since 2007, more than half the world’s population has been living in cities, and that share is projected to rise to 60 per cent by 2030.
Cities and metropolitan areas are powerhouses of economic growth—contributing about 60 per cent of global GDP. However, they also account for about 70 per cent of global carbon emissions and over 60 per cent of resource use.
Rapid urbanization is resulting in a growing number of slum dwellers, inadequate and overburdened infrastructure and services (such as waste collection and water and sanitation systems, roads and transport), worsening air pollution and unplanned urban sprawl.
The impact of COVID-19 will be most devastating in poor and densely populated urban areas, especially for the one billion people living in informal settlements and slums worldwide, where overcrowding also makes it difficult to follow recommended measures such as social distancing and self-isolation.
The UN food agency, FAO, warned that hunger and fatalities could rise significantly in urban areas, without measures to ensure that poor and vulnerable residents have access to food.
Sustainable Development Goals
The 2030 Agenda for Sustainable Development was adopted by all United Nations Member states in 2015, an agenda that provides a shared blueprint for peace and prosperity for people and the planet, now and into the future.
The 17 Sustainable Development Goals (SDGs) are an urgent call for action by all countries – developed and developing – in a global partnership. They recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and quality education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests. Learn more about the UN SDG’s.
What’s the goal here?
To make cities inclusive, safe, resilient and sustainable
Why?
Over 90 per cent of COVID-19 cases are occurring in urban areas, with the 1 billion residents of the world’s densely populated slums being hit the hardest. Even before the coronavirus, rapid urbanization meant that 4 billion people – over half of the global pupulation – in the world’s cities faced worsening air pollution, inade-quate infrastructure and services, and unplanned urban sprawl. Successful examples of containing COVID-19 demonstrate the remarkable resilience and adaptability of urban communities in adjusting to new norms.
What are some of the most pressing challenges that cities face today?
Inequality and the levels of urban energy consumption and pollution are some of the challenges. Cities occupy just 3 per cent of the Earth’s land, but account for 60-80 per cent of energy consumption and 75 per cent of carbon emissions. Many cities are also more vulnerable to climate change and natural disasters due to their high concentration of people and location so building urban resilience is crucial to avoid human, social and economic losses.
Why should I care?
All these issues will eventually affect every citizen. Inequality can lead to unrest and insecurity, pollution deteriorates everyone’s health and affects workers’ productivity and therefore the economy, and natural disasters have the potential to disrupt everyone’s lifestyles.
What happens if cities are just left to grow organically?
The cost of poorly planned urbanization can be seen in some of the huge slums, tangled traffic, greenhouse gas emissions and sprawling suburbs all over the world. By choosing to act sustainably we choose to build cities where all citizens live a decent quality of life, and form a part of the city’s productive dynamic, creating shared prosperity and social stability without harming the environment. As of May 2020, the majority of national and city governments are revisiting urban planning to help prevent the next pandemic.
9 in 10 people living in urban areas worldwide were breathing air that did not meet the World Health Organization’s air quality guidelines
Is it expensive to put sustainable practices in place?
The cost is minimal in comparison with the benefits. For example, there is a cost to creating a functional public transport network, but the benefits are huge in terms of economic activity, quality of life, the environment, and the overall success of a networked city.
What can I do to help achieve this goal?
Take an active interest in the governance and management of your city. Advocate for the kind of city you believe you need.
Develop a vision for your building, street, and neighborhood, and act on that vision. Are there enough jobs? Can your children walk to school safely? Can you walk with your family at night? How far is the nearest public transport? What’s the air quality like? What are your shared public spaces like? The better the conditions you create in your community, the greater the effect on quality of life.
