Sustainability is the property of biological systems to remain diverse and productive
indefinitely. In more general terms, sustainability is the endurance of systems and
processes. It includes the four interconnected domains: ecology, economics, politics, and
Sustainability science is the study of sustainable development and environmental
science. It can also be defined as a socio-ecological process characterized by the pursuit of
a common ideal. An ideal is by definition unattainable in a given time and space. However,
by persistently and dynamically approaching it, the process results in a sustainable system.
The sustainable cities emerged as a reaction to the industrial development and the spread
of advanced technology, which led to the pollution, and has become part of the
contemporary world. It has reached all aspects of life and has several forms; whether in
climate pollution, which extends through the effect of carbon dioxide and methane, and
causes damage to public health.
Methane is considered the most dangerous gas to the
planet and has a number of sources:
● Natural gas fields; where methane is considered the main component of natural
gas, with about 87% of the total extracted.
● Biogas, methane production is a part of the biogas production process through
fermentation and decaying of organic materials such as manure and sewage.
● Animal waste; some animals produce methane as part of the organic waste. For
example, cows produce about 16% of the amount of methane on earth.
● Atmospheric methane, which naturally resides as fixed ratios in the atmosphere,
but these proportions changed in recent years significantly due to climate pollution
“Green architecture” is a generic term intended to refer to the environmental awareness in
the field of architecture and of the most important principles of green architecture is to save
Sustainability designed to meet the needs of modern generations without ignoring the
needs of future generations, by increasing green spaces to face environmental pollution. It
also relies on clean and renewable energy sources, through recycling and limiting other
untapped wastes, as well as energy from waste extraction.
You can browse several specifications put forward by scientists to describe the sustainable
● The existence of plans for green space that is used in agriculture to meet the
needs of citizens.
● The existence of renewable energy sources like wind, water or biogas that is
extracted from the sewage stations.
● The existence of sources to reduce air adjustments, such as planting trees and
creating natural ventilation systems for homes and increasing the area of water
bodies and green spaces should not be less than 20% of the total urban area.
● Improve public transport and reduce its dependence on fossil fuels and tending to
increase its dependence on electrical energy in transportation.
● The existence of means to minimize the urban sprawl through finding ways to live
near work areas.
● Urban systems dependent on the renewable energy source such as solar energy.
● The use of technological means in the devices that have the ability to save energy.
The most interesting concept of sustainability is the architecture. Through the application of
the concept of sustainability in construction and urban planning, the work of restructuring
the industrial cities and urban areas to cope with the scientific concepts of sustainability.
The architectural designer must take into consideration when designing the green cities or
sustainable cities, the city’s environmental analysis, as well as be creating green spaces, and
the use of recycling in all aspects of construction. In addition, the reliance on renewable
energy sources such as wind and solar energy and hydropower, the industrial enterprises
must have facilities for waste treatment, recycling and reusing it in other industries. There
also must be means for rain flowing to the inflow, which can be used in renewable energy
Sustainable cities aim to restructure urban density in spite of the absence of international
standards for sustainable cities, but there is the organization of the “United Cities and Local
Governments (UCLG)”, which contains 60 members from across the world that aim to
develop standards and theses cities sustainability and urban development.
There are several examples of sustainable cities around the world, at the top of these are:
Zurich at the top of the list increased by 74.6%, came in second place Singapore City
increased by 74.1%, Stockholm increased by 73.9%, Vienna increased by 73.4%, London
increased by 73.2 %, Frankfurt increased by 70.6%, Seoul increased by 69.6%, Hamburg
increased by 69.2%, Prague increased by 69.1% and Munich increased by 68.6%.
In terms of the Middle East and developing cities are Abu Dhabi and Dubai on top of
sustainable cities in the Middle East, where they succeeded in reducing energy
consumption by more than 33% and by following the standards for sustainability and clean
We must mention the role of the known certificate “LEED” that assesses the degree of
sustainability in buildings or cities. It has several criteria including sustainable location as
well as efficient use of clean energy whether it’s the wind, water or solar energy or sewage.
It also assesses the quality of the internal environment and innovation, degrees in design,
the degree of decomposition of waste and recycling. LEED also undermines certification to
the degree of improvement of energy and this enhances the level of creative thinking in
finding creative forms of power generation and increases waste recycling efficiency.
The conference “Improving Sustainability Concept in Developing Countries” – is a great
chance for all who are interested in these topics and want to get more experience & amp;
exchange knowledge with peers and professors.
