Eco-cities

Last updated

An eco-city or ecocity is "a human settlement modeled on the self-sustaining resilient structure and function of natural ecosystems", as defined by Ecocity Builders (a non-profit organization started by Richard Register, who first coined the term). [1] Simply put, an eco-city is an ecologically healthy city. The World Bank defines eco-cities as "cities that enhance the well-being of citizens and society through integrated urban planning and management that harness the benefits of ecological systems and protect and nurture these assets for future generations". [2] Although there is no universally accepted definition of an 'eco-city', among available definitions, there is some consensus on the basic features of an eco-city.

The world's population is continuously increasing, which puts a tremendous amount of pressure on cities due to the need for new urban development. There is an urgent need for cities around the world to adapt ecologically based urban development to work towards sustainability. The dimensions of an ecocity provide solutions to improve the living conditions in cities by solving our current unsustainable practices. [3]

The cities around the world that face the most severe challenges associated with the world's urban population are those in developing countries. [4] Eco-cities are commonly found to focus on new-build developments, especially in developing nations such as China, wherein foundations are being laid for new eco-cities catering to 500,000 or more inhabitants. [5]

History

Origins

In the first half of the 19th century, the Garden City of Ebenezer Howard, the urbanistic thought of Frank Lloyd Wright and Le Corbusier laid the foundations for a radical change of paradigm and a comprehensive transformation in the urban planning canon. [6] During the post-war era, there was the spread of modernist tower blocks to satisfy the needs of urban slums. [6]

Initial ideas behind the eco-cities can be traced back to 1975 with the formation of a non-profit organization called Urban Ecology. [7] Founded by a group of visionary architects and activists including Richard Register in Berkeley, California, the organization worked at the intersection of urban planning, ecology, and public participation to help formulate design concepts centered around building environmentally healthier cities. [7] [8] Some of their efforts included initiating movements to plant trees along the main streets, promoting the construction of solar greenhouses, developing environment-friendly policies by working with the Berkeley city planning division and encouraging public transportation. [8] Building on these strategies, Richard Register later coined the term 'ecocity' in his 1987 book titled "Ecocity Berkeley: Building Cities for a Healthy Future" describing it as a city where human beings live in harmony with nature and therefore greatly reducing their ecological footprint. Urban Ecology began publishing articles focused on similar complex urban issues that elevated the movement further with the creation of their magazine, 'Urban Ecology' in 1987. For two decades, they also publish two newsletters, 'The Sustainable Activist' and 'The Urban Ecologist' to pursue their vision.

During the latter half of the 20th century, concepts surrounding environmentally friendly or nature-conscious communities expanded in scope, coinciding with a deeper understanding of ecological complexities. Recognizing the far-reaching consequences of ecosystem dynamics, pollution, and natural resource depletion, it became clear that a city's ecological footprint must be managed not only at the local level but also regionally and globally. An example of this is Wolman's urban metabolism model, which established a comprehensive accounting system for all materials and resources required by a city. McHarg, on the other hand, emphasized the necessity of city planning that aligns with the ecological and environmental conditions specific to each site. [9]

In the 1990s, there we two important events that began the initiative for eco-city developments. The first event involved the publication of the Brundtland Report. The Brundtland Report presented the idea of sustainable development. The second event occurred in 1992 at the United Nations Earth Summit. The members at the summit created a plan to apply sustainable development to our cities. The Eco-cities that were developed during this time period incorporated the concept of sustainable development. However, a majority of the developments were created to provide a vision of an eco-city. [10] Eco-cities have now become a popular way to create sustainable new urban development.

Eco-Cities in China have received strong support from the government since the early 2000s [11] as a policy to confront the nation's challenges with rapid urbanization and climate change. [12] Notably, China now boasts the world's largest eco-city development program, [13] with hundreds of eco-city projects currently in development. [14]

International Ecocity Conference Series aka Ecocity World Summit

Urban Ecology further advanced the movement when they hosted the first International Ecocity Conference in Berkeley, California in 1990. [15] The conference focused on urban sustainability problems and encouraged over 800 participants from 13 countries to submit proposals on best practices to reform cities for a better urban ecological balance.

Following this, in 1992, Richard Register founded the non-profit organization Ecocity Builders, to advance a set of goals outlined in the conference. Since its conception, the organization has been the convener of the International Ecocity Conference Series, now known as Ecocity World. The IECS has been the longest standing international conference series consisting of biennial Ecocity World Summits (EWS) and has been held in Adelaide, Australia (1992); Yoff, Senegal (1996); Curitiba, Brazil (2000); Shenzhen, China (2002); Bangalore, India (2006); San Francisco, United States (2008); Istanbul, Turkey (2009); Montreal, Canada (2011); Nantes, France (2013); Abu Dhabi, UAE (2015), Melbourne, Australia (2017); Vancouver, Canada (2019); and Rotterdam, the Netherlands (2022).

Other leading figures include architect Paul F. Downton and authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject.

Criteria

An ideal eco-city has frequently been described as one that fulfills the following requirements: [7] [16]

Besides these, each individual eco-city has an additional set of requirements to ensure ecological and economic benefits that may range from large-scale targets like zero-waste and zero-carbon emissions, as seen in the Sino-Singapore Tianjin Eco-city project and the Abu Dhabi Masdar City project, to smaller-scale interventions like urban revitalization and establishment of green roofs as seen in the case of Augustenborg, Malmö, Sweden. [17] [18] [19] [20] Cities that focus on the use of carbon-free sustainable energy and on managing greenhouse gas emissions can be referred to as zero-carbon cities. [21] [22] [23] [24]

Ecocity Framework and Standards

With a growing popularity of the concept, in the last few decades, there has been an exponential growth in the number of eco-cities established around the globe.[ citation needed ] To assess the performance of these eco-cities and provide future guidance, the Ecocity Framework and Standards, established by Ecocity Builders with technical support from the British Columbia Institute of Technology (BCIT) School of Construction and the Environment, provides a practical methodology for this to ensure progress towards the intended goals of eco-cities. The four pillars in this framework include:

Using these, the International Eco-Cities Initiative recently identified and rated as many as 178 significant eco-city initiatives at different stages of planning and implementation around the world. [25] To be included in this census, initiatives needed to be at least district-wide in their scale, covering a variety of sectors, and have official policy status. Although such schemes display great variety in their ambitions, scale, and conceptual underpinnings, since the late 2000s there has been an international proliferation of frameworks of urban sustainability indicators and processes designed to be implemented across different contexts. [26] This may suggest that a process of eco-city 'standardization' is underway.

VTT Technical Research Centre of Finland has formulated an EcoCity concept tailored to address the unique requirements of developing countries and emerging economies. Prominent reference examples include EcoCity Miaofeng in China, EcoNBC in Egypt, EcoGrad in St. Petersburg, Russia, UN Gigiri in Kenya, and MUF2013 in Tanzania. The modern challenges confronting cities, such as climate change and its interconnected social and technological issues, encompass climate mitigation, urban sustainability, housing affordability, integrated planning, energy accessibility, local capacity building, citizen engagement, and overarching concerns like gender equality and poverty reduction. VTT's EcoCity concept effectively addresses these challenges through collaborative partnerships with local stakeholders, enabling tailored solutions that align with specific local socio-economic contexts. [9]

Practical limits

Richard Register once stated that "An ecocity is an ecologically healthy city. No such city exists". [27] Despite the conceptual ecological benefits of eco-cities, actual implementation can be difficult to attain. The conversion of existing cities to eco-cities is uncommon because the infrastructure, both in terms of the physical city layout and local bureaucracy, are often major insurmountable obstacles to large-scale sustainable development. [28] The high cost of the technological integration necessary for eco-city development is a major challenge, as many cities either can't afford, or are not willing to take on, the extra costs. [29] Such issues, along with the added challenges and limits to retrofitting existing cities contribute to the establishment of newly constructed eco-cities. Along with this, the costs and infrastructure development needed to manage these large scale, two-pronged projects extend beyond the capabilities of most cities. [29] In addition, many cities around the world are currently struggling to maintain the status quo, with budgetary issues, low growth rates, and transportation inefficiencies, that encourage reactive, coping policies. [29] While there are many examples worldwide, the development of eco-cities is still limited due to the vast challenges and high costs associated with sustainability.

Eco-cities have been developed as a response to present-day unsustainable systems that exist in our cities. Simultaneously, there have been other concepts like smart cities, sustainable cities, and biophilic cities that also strive towards achieving sustainability in cities through different approaches. Owing to ambiguity in their definitions and closely related criteria defined to achieve their goals, these concepts, despite their varying approaches, are often used interchangeably. [30]

Criticism

Three pitfalls

Looking at the patterns of progress in the last few decades of city construction towards sustainability, Valaria Saiu (University of Cagliari) poses one major criticism through the existence of a theory-practice gap caused by economic and ethical conflicts and risks that generate socio-spatial utopias. [31] She identifies three pitfalls in the concept of sustainable cities (and therefore, eco-cities):

  1. The Idea of the City as a Business: "Most eco-city projects are dependent on technologies available on the global market and the city is considered as a big economic affair". [31] Often developed as techno-centric concepts, these projects seek investment opportunities by public-private partnerships leading to a top-down approach. [32] [33] [34] This structure lacks democratic approaches in the decision-making process which further contributes to running high risks of failure, especially in social terms.
  2. The Oversimplification of Urban Complexity: Due to the nature of current trends in measuring sustainability, there has been a strong focus in the quantifiable aspects of sustainability like energy-efficiency or waste-efficiency. [31] This creates a tendency of oversimplification by neglecting the social and political aspects of the city that are unmeasurable qualitative aspects, yet significant to the fundamental concept of eco-cities.
  3. The Quest for the Ideal Community: This section of the criticism focuses on the practical limits to merging economic goals with social goals in the urban development process. "Under the banner of green technology, inhabitants are forced to pay higher costs for their use of facilities in eco-cities." [35]

Eco-cities as isolated entities

Another larger conceptual criticism faced by eco-cities stems from the ambiguity in the definition of sustainability as a term. This has been further elaborated by Mike Hodson and Simon Marvin in their article titled 'Urbanism in the Anthropocene: Ecological Urbanism or Premium Ecological Enclaves' where they noted "We have tended to refer to sustainability in a generic sense, and our discussions of sustainability could be employed to anything that has sustainable as an adjective". [36] As a result of this, a widespread trend has been observed in the growing number of eco-cities developed over the past two decades that claim to combat our current global climate-change challenges. Many of these cities are found to be established in isolation from other existing urban centers due to the nature of their ownership.[ citation needed ] Owing to this isolation, internalization of resource-flows contribute towards a shallow sense of ecological sustainability in such cities. [36]

With regard to methods of emissions counting cities can be challenging as production of goods and services within their territory can be related either to domestic consumption or exports. Conversely the citizens also consume imported goods and services. To avoid double counting in any emissions calculation it should be made clear where the emissions are to be counted: at the site of production or consumption. This may be complicated given long production chains in a globalized economy. Moreover, the embodied energy and consequences of large-scale raw material extraction required for renewable energy systems and electric vehicle batteries is likely to represent its own complications – local emissions at the site of utilization are likely to be very small but life-cycle emissions can still be significant. [37]

Urban ecological security (UES) and the social, economic and environmental impacts of eco-cities

Eco-cities have also been criticized to have biases towards the economic and environmental pillars of sustainability while neglecting the social pillar.[ citation needed ] The practical translations of the concept have faced criticism as eco-cities have been driven by the demand for bounded ecological security. [36] By offering "premium ecological enclaves" factoring ecological security as an outcome of private investments driving the construction of eco-cities, the existing examples of eco-cities are criticized for not being truly sustainable solutions. [36] On the contrary, by placing this concept in the meta-narrative of sustainable cities, these have also been further criticized for celebrating this fragmentation of society through the development of gated communities and premium ecological enclaves isolated from the real global scale of issues in today's ecological crisis. For instance, the eco-cities of Masdar and Hong Kong pose homogeneous visions, but have been criticized to be the source of fragmentation of urban society.

The term "Frankenstein Urbanism" [38] was used by Federico Cugurullo to metaphorically symbolize this criticism of the concept that increases social stratification in exchange for ecological security, creating isolated entities that could work perfectly within themselves, but fall apart when brought in a larger view. [39]

<span class="mw-page-title-main">Ecovillage</span> Community with the goal of becoming more sustainable

An ecovillage is a traditional or intentional community with the goal of becoming more socially, culturally, economically, and/or ecologically sustainable. An ecovillage strives to produce the least possible negative impact on the natural environment through intentional physical design and resident behavior choices. It is consciously designed through locally owned, participatory processes to regenerate and restore its social and natural environments. Most range from a population of 50 to 250 individuals, although some are smaller, and traditional ecovillages are often much larger. Larger ecovillages often exist as networks of smaller sub-communities. Some ecovillages have grown through like-minded individuals, families, or other small groups—who are not members, at least at the outset—settling on the ecovillage's periphery and participating de facto in the community. There are currently more than 10,000 ecovillages around the world.

A Sustainable habitat is an ecosystem that produces food and shelter for people and other organisms, without resource depletion and in such a way that no external waste is produced. Thus the habitat can continue into the future tie without external infusions of resources. Such a sustainable habitat may evolve naturally or be produced under the influence of man. A sustainable habitat that is created and designed by human intelligence will mimic nature, if it is to be successful. Everything within it is connected to a complex array of organisms, physical resources, and functions. Organisms from many different biomes can be brought together to fulfill various ecological niches.

<span class="mw-page-title-main">Sustainable city</span> City designed with consideration for social, economic, environmental impact

A sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact, and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus will also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.

<span class="mw-page-title-main">Urban ecosystem</span> Structure of civilization

In ecology, urban ecosystems are considered a ecosystem functional group within the intensive land-use biome. They are structurally complex ecosystems with highly heterogeneous and dynamic spatial structure that is created and maintained by humans. They include cities, smaller settlements and industrial areas, that are made up of diverse patch types. Urban ecosystems rely on large subsidies of imported water, nutrients, food and other resources. Compared to other natural and artificial ecosystems human population density is high, and their interaction with the different patch types produces emergent properties and complex feedbacks among ecosystem components.

<span class="mw-page-title-main">Zero-carbon city</span> City that has no carbon footprint

A zero-carbon city is a goal of city planners that can be variously defined. In a narrower sense of energy production and use, a zero-carbon city is one that generates as much or more carbon-free sustainable energy as it uses. In a broader sense of managing greenhouse gas emissions, a zero-carbon city is one that reduces its carbon footprint to a minimum by using renewable energy sources; reducing all types of carbon emissions through efficient urban design, technology use and lifestyle changes; and balancing any remaining emissions through carbon sequestration. Since the supply chains of a city stretch far beyond its borders, Princeton University's High Meadows Environmental Institute suggests using a transboundary definition of a net-zero carbon city as "one that has net-zero carbon infrastructure and food provisioning systems".

<span class="mw-page-title-main">Micro-sustainability</span> Individual or small scale sustainability efforts

Micro-sustainability is the portion of sustainability centered around small scale environmental measures that ultimately affect the environment through a larger cumulative impact. Micro-sustainability centers on individual efforts, behavior modification, education and creating attitudinal changes, which result in an environmentally conscious individual. Micro-sustainability encourages sustainable changes through "change agents"—individuals who foster positive environmental action locally and inside their sphere of influence. Examples of micro-sustainability include recycling, power saving by turning off unused lights, programming thermostats for efficient use of energy, reducing water usage, changing commuting habits to use less fossil fuels or modifying buying habits to reduce consumption and waste. The emphasis of micro-sustainability is on an individual's actions, rather than organizational or institutional practices at the systemic level. These small local level actions have immediate community benefits if undertaken on a widespread scale and if imitated, they can have a cumulative broad impact.

<span class="mw-page-title-main">Green urbanism</span> Practice of creating communities beneficial to humans and the environment

Green urbanism has been defined as the practice of creating communities beneficial to humans and the environment. According to Timothy Beatley, it is an attempt to shape more sustainable places, communities and lifestyles, and consume less of the world's resources. Urban areas are able to lay the groundwork of how environmentally integrated and sustainable city planning can both provide and improve environmental benefits on the local, national, and international levels. Green urbanism is interdisciplinary, combining the collaboration of landscape architects, engineers, urban planners, ecologists, transport planners, physicists, psychologists, sociologists, economists and other specialists in addition to architects and urban designers.

<span class="mw-page-title-main">Sustainable urbanism</span> Study of cities and the practices to build them

Sustainable urbanism is both the study of cities and the practices to build them (urbanism), that focuses on promoting their long term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. Well-being includes the physical, ecological, economic, social, health and equity factors, among others, that comprise cities and their populations. In the context of contemporary urbanism, the term cities refers to several scales of human settlements from towns to cities, metropolises and mega-city regions that includes their peripheries / suburbs / exurbs. Sustainability is a key component to professional practice in urban planning and urban design along with its related disciplines landscape architecture, architecture, and civil and environmental engineering. Green urbanism and ecological urbanism are other common terms that are similar to sustainable urbanism, however they can be construed as focusing more on the natural environment and ecosystems and less on economic and social aspects. Also related to sustainable urbanism are the practices of land development called Sustainable development, which is the process of physically constructing sustainable buildings, as well as the practices of urban planning called smart growth or growth management, which denote the processes of planning, designing, and building urban settlements that are more sustainable than if they were not planned according to sustainability criteria and principles.
