Introduction
In todays's increasingly urbanised world, it is crucial to address the environmentally harmful impacts of urbanisation and strive towards creating urban spaces that are not only eco-friendly but also desirable places to live.
Imagine vibrant cities that harmoniously integrate green spaces, adopt renewable energy sources, prioritize efficient transportation systems, and promote self-sufficiency in food production. These are urban areas of the future that can truly enhance our quality of life and protect the environment for generations to come.
But the question arises, how can each of us contribute to this transformation? It starts with our individual choices and actions, encompassing various aspects such as where we choose to live, how we commute, how we consume resources, and how we manage waste.
In this enlightening blog post, we will delve into the strategies, initiatives, and inspiring examples from cities worldwide that are already making significant progress towards creating sustainable and livable urban environments. You will discover how ecocities, green cities, and innovative approaches are paving the way for a future where nature and urban life coexist harmoniously.
Why Should You Care About Urbanisation?
One reason why you should care about urbanisation is that chances are you live, or will someday live, in an urban area, and the environmentally quality of that area will have a major effect on the quality of your life.
Another reason to care is that the world's urban areas are large contributors to the global environmental problems we face, including air and water pollution, projected climate disruption, and depletion of resources such as topsoil, minerals, freshwater supplies, and wetlands. In fact, many environmental analysts argue that the great majority of the world's urban areas are currently not environmentally sustainable for the long term.
Even if you don't live in an urban area, you have reasons to care about the environmental quality of these areas. Many of the air pollutants, water pollutants, and solid wastes coming from cities end up in the rural areas around them. In addition, rural areas are exploited through industralised agriculture, mining operations, and the clear-cutting of forests in order to provide resources for urban dwellers. Such operations often disturb soils, pollute air and water, degrade or destroy forests, and eliminate wildlife habitats.
Urban areas occupy only about 2% of the earth's land area. But a populous urban area depends on a flow of resources from other areas to meet most of its residents' needs and wants, while a portion of its pollution and wastes flows into the air and water needed to provide any set of urban dwellers with their food, water, and other vital resources, and to absorb their wastes and pollutants is typically much larger than the area of the city in which they live (Figure 1). In other words, an area can have an ecological footprint that extends far beyond its physical boundaries.

On the other hand, urbanisation or the growth of cities can also have beneficial effects on the environment. For example, with higher concentrations of people and material goods, cities can more easily support recycling programmes than can small towns and rural areas. They can also support mass-transit systems such as buses and light-rail systems. This helps reduce energy use and the pollution that results from high concentrations of motor vehicles used daily. In addition, where urban growth is managed in such a way that the human population is more concentrated in the city and not spread out across a vast area around the city, we can preserve larger areas of land for the benefit of wildlife, ecosystems, ecosystem services, and people (see Figure 2).

Furthermore, city living can provide a variety of social and economic benefits. Cities are the sites of businesses and industries that provide jobs for millions of people. Most colleges and universities are located in urban areas. Cities are also centres of commerce, technological advances, arts and entertainment, and economic and political power.
On average, urban dwellers live longer than do rural residents, and their children are more likely to be able to go to school. Urban area residents also tend to have better access to health care, family planning, and social services than do people in rural areas. Many people living in rural areas, especially young people, migrate to cities in hopes of gaining these social and economic benefits.
How to Make Urban Areas More Sustainable and Livable?
In a number of cities around the world, officials, planners, and residents are working hard to make their urban areas more sustainable and livable, using well-tested policies, tools, and technologies. Many of these people envision what can be called an ecocity or a green city. This city puts its highest priority on minimising its ecological footprint and improving the quality of life of its inhabitants.
Cities that are pursuing the ecocity model distinguish themselves from conventional cities in several ways. New neighbourhoods in these cities are designed to be more pedestrian-friendly. Instead of having wide, multilane streets and highways, they have mostly narrow streets and wide sidewalks and paths for walking and biking (Figures 3 & 4). These cities also rely more on affordable, energy-efficient mass transit (Figure 5), neighbourhoods with a mixture of housing and businesses, and compact development.

Ecocity developers try to preserve surrounding croplands and protect and restore nearby natural wildlife habitats and wetlands. Trees and plants adapted to the local climate and soils are planted throughout ecocities to provide shade, beauty, and wildlife habitat, and to reduce air pollution, noise, and soil erosion (Figures 4 & 6).
Green cities work toward sharply reducing pollution and the waste of energy and matter resources. In addition to encouraging their residents to reduce the use of these resources, ecocities also have strong programmes to promote reuse, recycling, and composting (Figure 7). Garden trimmings, waste food, and even waste sewage can be converted to plant nutrients, as in natural systems, or converted to biogas fuel. Some green cities recycle or compost 60% or more of all municipal solid waste.
Energy resources are carefully chosen and promoted in ecocities. To produce electricity, many use wind turbines, solar cells and other locally available, renewable energy resources (Figure 8). As a result, homes and other buildings using these systems can often serve as miniature power plants by selling their excess electricity back to power companies.

In addition to striving for self-sufficiency in terms of energy resources, ecocity residents also try to be more self-sufficient in their food supplies. Some cities have community urban gardens (Figures 9) and farmers markets. Instead of maintaining grass lawns, some people fill their lots with organic gardens and various plants adapted to local climate conditions. People also use nearby farms and small gardens on rooftops (Figures 10), in yards, and even in window boxes.
