The concept encompasses the ability of a city to maintain environmental, social, and economic systems over time. It involves practices and policies that ensure a high quality of life for current residents without compromising the ability of future generations to meet their own needs. A specific example is a municipality investing in renewable energy sources, reducing its carbon footprint, and creating green jobs, all while promoting equitable access to resources for all its inhabitants.
Its importance lies in mitigating the negative impacts of urbanization, such as pollution, resource depletion, and social inequality. Successful implementation leads to enhanced resilience to climate change, improved public health, and a more robust and equitable economy. Historically, growing awareness of environmental degradation and social disparities associated with rapid urban growth has driven the development and adoption of these strategies.
