THE FUTURE RELIES ON THIS!
WHY ECO CITIES ?
The world is increasingly URBAN. Since 2008, more than half of the world’s
population is living in urban areas. The number of urban residents is expected
to continue to grow, especially in developing countries. In Asia, some 1.1 billion
are anticipated to move to cities in the next 20 years This includes 11
megacities, each with a population exceeding 10 million, for example, Beijing,
Shanghai, Kolkata (Calcutta), Delhi, Jakarta and Tokyo. The expanding
urban population will require a whole range of infrastructure, services, housing
and jobs, not to mention land. The urban land expansion could threaten
agricultural land supply, cause growth in traffic volumes and increased pressure
on the environment, and be massively unsustainable for the country and the
rest of the planet. Ecologists have long argued for equilibrium with basic
ecological support systems, and since the 1987 Brundtland Commission, the
notion of sustainable development has taken on renewed and urgent currency
Nations 1987, Urban land use planning can no longer afford to be merely
anthropogenic (human-centred). Instead, it has to also consider environmental
issues including the interdependency of human and non-human species. . It has
to be ecological. Ecological planning involves conceptual thinking in
environmental urban sustainability, land use allocations, spatially designed and
distribution patterns that contribute and lead to achieving such objectives of
ecological balance.
WHAT IS AN ECO CITY ?
An eco-city is a city built off the principles of living within the means of the environment. The ultimate goal of many eco-cities is to eliminate all carbon waste, to produce energy entirely through renewable sources, and to incorporate the environment into the city; however, eco-cities also have the intentions of stimulating economic growth, reducing poverty, organizing cities to have higher population densities, and therefore higher efficiency, and improving health.
The holistic concept of Eco-City has a balanced relationship between the urban
(city) and the rural (countryside).
The concept of the “eco-city” was born out of one of the first organizations focused on eco-city development, “Urban Ecology.” The group was
founded by RICHARD REGISTER in Berkeley, California in 1975, and was founded with the idea of reconstructing cities to be in balance with nature. They worked to plant trees along the main streets, built solar greenhouses, and worked within the Berkeley legal system to pass environmentally friendly policies and encourage public transportation. Urban Ecology then took the movement another step further with the creation of The Urban Ecologist, a journal they started publishing in 1987.
WHO GAVE THE CONCEPT ?
THE IDEAL ECO CITY
• an urban ecosystem which is ecologically sound minimizing the
negative impact of development on the environment.
• Reduction of ecological footprint , waste management and its utilization.
• Achieving environmental sustainability through reduced greenhouse gas
emissions, utilization of renewable energy, and green transportation.
• Creation of a vibrant economy through environment-friendly production and
industry that supports high capita gross domestic product (GDP) level
• Maintaining high air and water quality standards and an above-average
ratio of
green space per capita
• rain water harvesting systems, least usage of fossil fuels
• Protection of ecologically sensitive habitats, physical and nonphysical
cultural
legacies and promotion of green lifestyles and regional integration.
is a city that fulfils the following criteria :
Major ecocities around the
worldAUSTRALIA
Melbourne, City of MorelandThe City of Moreland in Melbourne's north, has programs for becoming carbon neutral amongst other existing
sustainable implementations and proposals.
City of MelbourneOver the past 10 years, various methods of improving public transport have been implemented, car free zones
and entire streets have also been implemented.
CHINA
Dongtan, a planned city was intended to be an eco-city.
Huangbaiyu (currently in construction)
Rizhao (which currently
mandates use of solar power for
heating water)
parts of districts in Shanghai that
are working on green
development.
China is working with investment
and technology supplied by the
Singapore government to build an
eco-city in the Coastal New
District of Tianjin City in northern
China, named the Sino-
Singapore Tianjin Eco-city.
GERMANY
No other country has built more eco-city projects than Germany.
Freiburg im Breisgau is often referred to as green city. It is one of the few cities with a green mayor and is
known for its strong solar economy.
Vauban, Freiburg is a sustainable model district. All houses are built to a low energy consumption standard
and the whole district is designed to be car-free
INDIA
Gujarat International Finance Tec-City or GIFT.An under-construction world-class city in the Indian state of Gujarat. It will come up on 500 acres (2.0 km2) land. It
will also be first of its kind fully Sustainable City.
Manimekala Hightec Eco cityProjected in Karaikal, India. An area of 5 km2. It will be first of kind in South India.
SWEDEN
Gothenburg and especially Alvstaden (central city by the river Göta Älv) are good examples of sustainable
city in Sweden. They have low environmental impact, contain passive houses, good recycling system for waste,
etc.
Hammarby Sjostad, Stockholm is also a good example.
UNITED ARAB EMIRATES
Masdar CityThis city is located in Abu Dhabi in the growing Middle East. It is a zero-carbon, zero-waste city that is fully
sustainable and only 11 miles in size.
And, there are several more eco cities in the world like these. The way things are going on
in the environment, ecocities are the FUTURE for SUSTAINABLE DEVELOPMENT.
