As you can find on Wikipedia: “Sustainable development is the organizing principle for meeting human development goals while at the same time sustaining the ability of natural systems to provide the natural resources and ecosystem services upon which the economy and society depend.”
In order to understand that, we need to be aware that more than half of the world’s population lives in cities, which are today growing faster than ever. According to the UN, almost one billion people live in informal settlements adjacent to cities, and the UN predicts that in the next 20 years, another two billion people will live in cities in developing countries.
These slum areas are often overcrowded and lack clean water, as well as effective solutions for sanitation, energy supply and waste management. At the same time, negative effects of climate change will affect the citizens even more. Because of this, it is important that the global growth of cities occurs in a sustainable way.
While urbanisation contributes to economic growth and development, an increased migration to cities also means a greater pressure on the environment. Involving citizens and several sectors of society in urban planning is crucial if urbanisation is to be sustainable.
In Cities that grow uncontrollably often affect poor and marginalised people in a negative way. The impact of growth on all areas of society must be acknowledged. Sustainable growth requires an evolution in the way urban areas carry out their activities such as resource use and the movement of people and goods. The physical infrastructure in addition to social and economic processes must evolve to acknowledge the challenges of growth.
As population grows the urbanisation of society is inevitable. Urbanisation leads to an increased impact.
The one of the goals is that cities should be healthy, providing housing and employment opportunities, meet environmental standards and be sustainable. Sustainability needs to be an addressed on a global scale, reforms need to concentrate on the interaction of the urban environment with the global economy and environment.
Promoting a more sustainable use of natural resources is also important, for example through new technologies, recycling and safe management of chemicals.
The concept of sustainable development has been—and still is—subject to criticism, including the question of what is to be sustained in sustainable development. It has been argued that there is no such thing as a sustainable use of a non-renewable resource, since any positive rate of exploitation will eventually lead to the exhaustion of earth’s finite stock, this perspective renders the Industrial Revolution as a whole unsustainable.
Sustainable urban development highlights the need for reform of market mechanisms to achieve environmental goals and the achievement of a balance with social and economic considerations.
Several themes common to all definitions of sustainable urban development have emerged:
- A change in the quality of growth
- The conservation and minimisation of the depletion of non-renewable resources
- A merging of economic decisions with those on the environment
- A strong consideration of the needs of future generations
And highlight should be:
- Urban planning principles
- Influence of urban development on people lives and habits
- Transportation requirements for people and goods
- Influence of globalization on urban landscape
- Climate change and financial sustainability of urban centers
It is very important fact that Asia has almost 45% of the world’s population and six of the world’s largest cities and cannot allow research to behind Europe, but steel little research on urban sustainability has been conducted in Asia. Major development agencies (such as the World Bank, the Asian Development Bank and the United Nations Development Programme) should undertake more significant work on urban development;
- Promoting the social dimension of sustainable urban development through inclusive and save cities in order to better fight against urban poverty and exclusion;
- Promoting green and resilient cities. Environmental sustainability is fundamental to ensuring the prosperity and well-being of all people within planetary boundaries;
- Promoting prosperous and innovative cities with a particular focus on growth and job creation;
- Promoting good urban governance by strengthening the capacity of the authorities at all levels of government in integrated planning and public finance management, by establishing adequate legal and policy frameworks, by fostering access to public and private investments by municipalities, and by fostering women empowerment in urban governance matters.
The desired result is a state of society where living conditions and resource use continue to meet human needs without undermining the integrity and stability of the natural system. Sustainable development can be classified as development that meets the needs of the present without compromising the ability of future generations.
