Lecture - what I have learnt today
Sustainability is the capacity to endure. Towards the end of the 1980s, the concept of sustainable development was introduced in urban development. Sustainable development reflects the hope of improving the quality of life while living within the earth's carrying capacities. So, sustainable development refers to the mode of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Indeed, a sustainable city is a city which applies the concept of sustainable development. In a sustainable city, we have to meet the demands of present-day:
- economic needs
- social, cultural and health needs, and
- political needs (including freedom of all participation by all people)
without compromising the ability of future generations to meet their own needs.
How to measure sustainability
In order to develop a sustainable city, we need to set some sustainability indicators. These indicators have been adopted by different countries and regions. They show how sustainable a city is. They also help governments to carry out better planning in order to achive sustainable development in cities.
