Sustainable community

Last updated

The term "sustainable communities" has various definitions, but in essence refers to communities planned, built, or modified to promote sustainable living. Sustainable communities tend to focus on environmental and economic sustainability, urban infrastructure, social equity, and municipal government. The term is sometimes used synonymously with "green cities," "eco-communities," "livable cities" and "sustainable cities."

Sustainable living describes a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources, and one's personal resources. It is often called as "earth harmony living" or "net zero living". Its practitioners often attempt to reduce their ecological footprint by altering their methods of transportation, energy consumption, and/or diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development.

Sustainability process of maintaining change in a balanced fashion

Sustainability is the ability to exist constantly. In the 21st century, it refers generally to the capacity for the biosphere and human civilization to coexist. It is also defined as the process of people maintaining change in a homeostasis balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations. For many in the field, sustainability is defined through the following interconnected domains or pillars: environment, economic and social, which according to Fritjof Capra is based on the principles of Systems Thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political. According to Our Common Future, Sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs.” Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical.


Different organizations have various understandings of sustainable communities; the term's definition is contested and still under construction. For example, Burlington, Vermont's Principles of Sustainable Community Development [1] stress the importance of local control of natural resources and a thriving non-profit sector to a sustainable community. The Institute for Sustainable Communities outlines how political empowerment and social well-being are also part of the definition. [1] Additionally, referring to communities in Shanghai and Singapore, geographer Lily Kong has paired concepts of cultural sustainability and social sustainability alongside environmental sustainability as aspects of sustainable communities. [2] Meanwhile, the UK's 2003 Sustainable Communities Plan often abbreviates its definition of sustainable communities as "places where people want to live and work, now and in the future". [3] Addressing the scale of sustainable communities, political scientist Kent Portney points out that the term sustainable communities has been used to refer to a broad variety of places, ranging from neighborhoods to watersheds to cities to multi-state regions. [4]

Burlington, Vermont Largest city in Vermont

Burlington is the most populous city in the U.S. state of Vermont and the seat of Chittenden County. It is located 45 miles (72 km) south of the Canada–United States border and 94 miles (151 km) south of Montreal. The population was 42,417 as of the 2010 census. It is the least populous municipality in the United States to be the most populous incorporated area in a state.

Institute for Sustainable Communities organization

The Institute for Sustainable Communities (ISC) is an independent, tax-exempt, nonprofit organization whose primary work includes finding community-based solutions to reducing climate pollution in the U.S. and China, building the capacity of civil society in the Balkans, and helping communities along the U.S. Gulf Coast and China recover from disasters. ISC provides training, technical assistance and financial support to communities, nonprofits/nongovernmental organizations, businesses and local governments.

Lily L.L. Kong is a Singaporean geographer and the current President of Singapore Management University (SMU). She is the first woman and the first Singaporean academic to helm a Singaporean university. Before joining SMU, she was a faculty member at the Department of Geography of the National University of Singapore (NUS) and had held various senior managerial positions at NUS.

Etymologically, the term "sustainable community" grew out of the related discourses of "sustainability" and "sustainable development" that gained widespread use among local, national, and international politicians and policymakers in NGOs starting in the late 1980s. [5] The term originally referred to environmental concerns and was later applied to cities. [6]

Sustainable development is the organizing principle for meeting human development goals while simultaneously sustaining the ability of natural systems to provide the natural resources and ecosystem services based upon which the economy and society depend. The desired result is a state of society where living conditions and resources are used to continue to meet human needs without undermining the integrity and stability of the natural system. Sustainable development can be defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Examples of Sustainable Community initiatives

The best example of a real Sustainable Community is Saint Michael's Sustainable Community in Costa Rica. The community produces far more food and water then it needs. It uses regenerative agriculture as a base to live in harmony with nature.

Sustainable community initiatives have emerged in neighborhoods, cities, counties, metropolitan planning districts, and watershed districts at different scales pertaining to community needs. These initiatives are driven by various actor groups that have different methods of effectively planning out ways to create sustainable communities. Most often they are implemented by governments and non-profit organizations, but they also involve community members, academics, and create partnerships and coalitions.

Metropolitan area region consisting of a densely populated urban core and its less-populated but economically-linked surroundings

A metropolitan area is a region consisting of a densely populated urban core and its less-populated surrounding territories, sharing industry, infrastructure, and housing. A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

Nonprofit organizations help to cultivate local talents and skills, empowering people to become more powerful and more involved in their own communities. Many also offer plans and guidance on improving the sustainability of various practices, such as land use and community design, transportation, energy efficiency, waste reduction, and climate friendly purchasing.

The term empowerment refers to measures designed to increase the degree of autonomy and self-determination in people and in communities in order to enable them to represent their interests in a responsible and self-determined way, acting on their own authority. It is the process of becoming stronger and more confident, especially in controlling one's life and claiming one's rights. Empowerment as action refers both to the process of self-empowerment and to professional support of people, which enables them to overcome their sense of powerlessness and lack of influence, and to recognize and use their resources. To do work with power.

Some government groups will create partnerships where departments will work together using grants to provide resources to communities like clean air and water, community planning, economic development, equity and environmental justice, as well as housing and transportation choices.

Economic development is the process by which the economic well-being and quality of life of a nation, region or local community are improved. The term has been used frequently in the 20th and 21st centuries, but the concept has existed in the West for centuries. "Modernization", "Westernization", and especially "industrialization" are other terms often used while discussing economic development.

Environmental justice

Environmental justice emerged as a concept in the United States in the early 1980s. The term has two distinct uses with the more common usage describing a social movement that focuses on the fair distribution of environmental benefits and burdens. The other use is an interdisciplinary body of social science literature that includes theories of the environment and justice, environmental laws and their implementations, environmental policy and planning and governance for development and sustainability, and political ecology.

Housing, or more generally living spaces, refers to the construction and assigned usage of houses or buildings collectively, for the purpose of sheltering people — the planning or provision delivered by an authority, with related meanings. The social issue is of ensuring that members of society have a home in which to live, whether this is a house, or some other kind of dwelling, lodging, or shelter. Many governments have one or more housing authorities, sometimes also called a housing ministry, or housing department.

Social movements have gathered momentum, spreading sustainable community ideas around the world, not only through example, but also by offering classes and training on sustainable living, permaculture, and local economics.

International initiatives

United Kingdom

The Sustainable Communities Plan was launched in 2003 through the Office of the Deputy Prime Minister. Lacking an official national spatial development plan, the UK employed the Sustainable Communities Plan as a regional development plan targeted at the South East of England. [7] Additionally, the plan created the Academy for Sustainable Communities. The £38 billion plan identifies four key growth areas for development and regeneration: the Thames Gateway, Ashford, Kent, London-Stansted-Cambridge-Peterborough (LSCP) and Milton Keynes/South Midlands (MKSM) [3] . Designed during a period that projected sustained economic growth into the future, the plan's implementation has been slowed and disjointed, particularly since the 2008 economic recession [7] An affordable housing shortage in the UK has also challenged the Plan's implementation. [6]

National initiatives

The Partnership for Sustainable Communities is an interagency partnership between the Department of Transportation, Environmental Protection Agency, and the Department of Housing and Urban Development. These departments work together with a mission to “improve access to affordable housing, increase transportation options, and lower transportation costs while protecting the environment”. [8] All three bureaus offer funding opportunities to support communities in areas of clean air and water, community planning, economic development, energy efficiency, equity and environmental justice, as well as housing and transportation choices. The partnership incorporates six principles of livability into its grant-making and program development.: [8]

Along with working collaboratively, these government agencies also have their own initiatives. The Department of Housing and Development has an Office of Sustainable Housing and Communities which features a Sustainable Housing Initiative, aiming at “supporting the construction and rehabilitation of green affordable housing [9] and does this through programs that retrofit or construct energy efficient homes. They also work to standardize energy efficiency standards across federal agencies, as well as expand the availability of financing for home energy improvements and multifamily housing.

The Environmental Protection Agency has a Smart Growth Program which conducts research, publishes reports, showcases outstanding communities, and works with communities through grants and technical assistance. [10] They also have a Green Communities Program which provides communities with a tool kit of information to help them reach sustainable goals. The tool kit is arranged in a five-step program which allows communities to: [11]

The Department of Transportation has a Livability Initiative which issues “grants to eligible recipients for planning, vehicle purchases, facility construction, operations, and other purposes”, [12] with numerous goals, including the improvement of surface transportation, providing public transit on Indian reservations, providing access to disadvantaged communities, etc.

Case Studies from the Partnership for Sustainable Communities

The Euclid Corridor in Cleveland

Once a thriving place of business and home to the wealthy and elite, Euclid Avenue in Cleveland had seen a decline in commerce following the Great Depression. During this economic downturn, Cleveland became a shrinking city as many of its residents moved and homes were turned into boarding houses or abandoned altogether.. After decades of work by city leaders and residents to revitalize this part of the city, the bus line HealthLine debuted in 2008. This bus line increased ridership and helped The Euclid Corridor begin to see the redevelopment of abandoned properties as well as investment in development of commerce, to the tune of $4.3 billion. This created thousands of square feet of retail space and thousands of jobs. The success of the revitalization of the Euclid Corridor is due in large part to engaged community leaders, community members, and NGO's like MidTown Cleveland who worked on ensuring that there was a variety of housing investments. EPA assisted with the redevelopment of abandoned space through their brownfield assessment grants and HUD provided mortgage insurance on properties to aid in the development of Euclid Avenue. [13]

Greenville, South Carolina's Westside

Following a shift from the cotton production that once thrived in the west end of Greenville, South Carolina, this part of the city began to see a flight of its residents and with it the abandonment and decay of its buildings and facilities, higher crime rates, and more low-income households. In 2010, HUD and DOT awarded the city $1.8 million to support a three-year planning initiative which sought to improve affordable housing, transportation, and increase economic development. The HUD provided a loan to encourage economic growth, specifically through the conversion of an old cotton warehouse into an area of retail shops, offices, and restaurants known as West End Market. The success of West End Market led to 230 building permits being issued around the area in a three-year period, resulting in a successful arts district that created jobs as well as drew tourists and locals. EPA assisted with the redevelopment of abandoned space through $200,000 in brownfield assessment grants which allowed for the city to facilitate clean up, or initiate redevelopment. The city also worked with the Federal Highway Administration in demolishing an unnecessary bridge which allowed for the development of a recreational area with a cross bridge, waterfalls, and walking paths, known as Falls Park on the Reedy. In 2005, a mixed-use development was constructed across from Falls Park with a hotel, apartments, restaurants, and retail and office spaces to help further spark economic growth in the area. [14]

Seattle's South Lake Union Neighborhood

With investments in transportation, affordable housing, and green space, Seattle's South Lake Union has transformed from a place of freeway traffic, abandoned warehouses, and parking lots to an economically flourishing neighborhood. An integral part to this transformation was the creation of a street car service, partially funded by the Federal Transit Administration. The streetcar encouraged both and Microsoft to locate campuses in the South Lake Union neighborhood, bringing with it jobs and investment in residential space. The City of Seattle is proposing a zoning change to promote affordable housing and attract market rate development. HUD provided grants to fund building and support services for the chronically homeless, adults and veterans recovering from addiction, and homeless with mental health issues and substance abuse problems. HUD also supplied $5.7 million towards the construction of a senior housing facility. To address the problems with the neighborhoods freeways and lack of sidewalks and crosswalks, a $30 million grant was issued by the DOT to help build crosswalks over 12 intersections, widen sidewalks, add bicycle lanes, as well as beautify the space through the addition of landscaping and trees. [15]

State initiatives


The state of Maryland passed a Sustainable Communities Act in 2010 with the goal of revitalizing and promoting reinvestment in Maryland's older communities as well working to promote “equitable, affordable housing by expanding energy-efficient housing choices for people of all ages, incomes, races, and ethnicity to increase mobility and lower the combined cost of housing and transportation”. [16] The law also created the Sustainable Communities Tax Credit Program which promotes private investment in the restoration and development of historic sites. [17] Thanks in part to the Sustainable Communities Tax Credit Program, the neighborhood of Remington, Baltimore was able to refurbish an old tin factory into a space for offices and residences, which led to the development of other properties as well as homes, which increased use and population for the neighborhood. [18]

In 2013 the Maryland General Assembly passed the Sustainable Communities Tax Increment Financing Designation and Financing Law. This law allows for Maryland counties and municipalities to use funds generated from increased property tax values to fund improvement projects in sustainable communities. Sample projects include expanding sidewalks, the development of tree planting on streets and parks, as well as improvements to water and sewer infrastructure to help encourage economic growth and improve quality of life. [19]


The state of California passed the Sustainable Communities and Climate Protection Act of 2008, also known as SB 375. The law aims to reduce greenhouse gas emissions through transportation, housing, and land use planning. Under the SB 375, the state is broken up into Metropolitan Planning Organizations which are each responsible for developing Sustainable Community Strategies that will help the state reach its goal of reduced emissions. These strategies are then evaluated by the California Environmental Protection Agency's Air Resources Board. [20] Under the Sustainable Community Strategy, the city of Sacramento plans to double transit service and increase bike lanes, offering more transportation choices and reducing vehicle emissions. [21] The city of San Diego also plans to increase funding towards more transportation choices as well as promote more multi-family housing near high transit areas. [21] The Southern California Strategies include transit expansion, developing housing closer to public transportation, increasing funding for biking and pedestrians, and the creation of jobs, with most being near public transit. [21]

City government initiatives

Cities are defined as jurisdictional units that have small divisions of government within them. These divisions of government have the authority to affect environmental and ecological results. [4] Cities are especially important in initiating sustainable communities because they have local authorities that “have political power and credibility to take initiatives to access and deploy resources in ways reflecting local conditions that allows them the capacity to manage and lead urban development for the good of the environment.” [4] It is also necessary to implement sustainable communities in countries that are industrialized because cities are where most environmental and social problems dwell.

When looking at and comparing sustainable cities certain indicators may be used:

The 34 elements inside “Taking Sustainable Cities Seriously" can also be used to determine whether a city is considered sustainable or not. [24]

City examples

The city of San Francisco uses the Precautionary Principal as a framework to develop laws for a healthier and more just city. [25] The precautionary principal gives more power to community members by allowing them to stand up against corporations in their neighborhoods and leaves the burden of proof to corporations instead of community members. Companies must prove that their endeavors are harmless to the community instead of the community having to prove they have been harmed by company endeavors. [23] This allows for a sustainable community as environmental justice and social justice are created.

The city of Quebec to create a sustainable community through political involvement has dedicated studies to discovering why citizens are or are not politically active. Studies from Quebec have shown that citizens’ internal and external efficacy is a large part in determining participation in politics. When citizens lack the internal belief that one can make change in government and the external belief that the government will make changes according to citizen concerns, political participation dwindles as citizens believe no change will occur. When becoming politically active, a citizen takes into account the history of the city government, the government's actions, and government interactions with other citizens. [26]

After noting the city's sustainability level it is important to note what kinds of communities are targeted and how they are affected through these programs and what kinds of strategies are being used to try to create and transform sustainable communities.

Non-Profit and NGO sector

The Institute for Sustainable Communities created by former Vermont Governor, Madeleine M. Kunin, leads community based projects around the globe that address environmental, economic, and social issues. [27] Many of these groups help to cultivate local talents and skills, empowering people to become more powerful and involved in their own communities. Many also offer plans and guidance on improving the sustainability of various practices, such as land use and community design, green transportation, energy efficiency, waste reduction, and climate friendly purchasing. [28]

The Global Integrity Project is focused on bringing together top scientists and thinkers from around the world in order to analyze the problems of inequality among humankind. These thinkers examine economic and ethical issues faced in protecting and enhancing our environments and make recommendations on restoration techniques that aid in promoting social justice. They also call for a major and imperative paradigm shift in order to ensure good quality of life for many future generations. [29]

Sustainable Seattle is a non-profit organization which has created regional indicators for sustainability through grassroots activism and has become a world leader in these sustainability indicators. Sustainable Seattle has printed newsletters on a wide range of sustainable community topics, from building to recycling and more, and they are believed to be the first “sustainable community” organization, founded in 1991. There are now hundreds of “sustainable community” organizations across the USA [30]

Social movement initiatives

The Take Back Your Time Movement, led by John de Graaf, focuses on the concept of working fewer hours and devoting more time to living a healthy lifestyle. The movement suggests that allowing shorter work days and longer vacations would in turn help better distribute work, while also reducing stress and making for healthier living. Additionally, people would have more free time to make more rewarding and sustainable choices for themselves. [31]

The Voluntary Simplicity Movement or Simple Living movement emphasizes reducing one's material possessions and desires and increasing self-sufficiency through skills such as gardening and DIY. The Voluntary Simplicity Movement suggests that one should focus on cultivating their own best inner being rather than focus on making material gains and wealth. It also promotes activism within the community to create engaged, educated citizens.

The Degrowth movement is based on anti-consumerist and anti-capitalist ideas, focusing on reducing consumption and promoting happy, healthy lifestyles in non-consumptive fashions. Main aspects of Degrowth include more equal distribution of workload and sharing work, consuming less, and setting aside time for personal and cultural growth through the arts and creativity [32]

Movements such as ecovillages are gathering momentum, spreading sustainable community ideas around the world, teaching through example and also offering classes and training on sustainable living, permaculture, and local economics. Ecovillages seek to integrate themselves harmlessly into the ecosystem surrounding them, so as to live and interact in a way that is sustainable and supportive of the natural world [33]

Challenges and critiques

Sustainable communities, both as individual projects and as a whole, have faced challenges impeding their development and have been met with criticism.

Sustainable communities projects have struggled to take hold for:

Projects have been critiqued for:


While there are a variety of graduate degrees at universities that touch on sustainability as it related to urban planning and environmental resources, only a few degree program programs exist that train students in the theory and practice of sustainable communities. The most notable examples are:

Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid sprawl. It also advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. The term "smart growth" is particularly used in North America. In Europe and particularly the UK, the terms "compact city", "urban densification" or "urban intensification" have often been used to describe similar concepts, which have influenced government planning policies in the UK, the Netherlands and several other European countries.

United States Department of Housing and Urban Development Cabinet department in the Executive branch of the United States federal government

The United States Department of Housing and Urban Development (HUD) is a Cabinet department in the Executive branch of the United States federal government. Although its beginnings were in the House and Home Financing Agency, it was founded as a Cabinet department in 1965, as part of the "Great Society" program of President Lyndon Johnson, to develop and execute policies on housing and metropolises.

The Community Development Block Grant (CDBG), one of the longest-running programs of the U.S. Department of Housing and Urban Development, funds local community development activities with the stated goal of providing affordable housing, anti-poverty programs, and infrastructure development. CDBG, like other block grant programs, differ from categorical grants, made for specific purposes, in that they are subject to less federal oversight and are largely used at the discretion of the state and local governments and their subgrantees.

Urban agriculture The practice of cultivating, processing and distributing food in or around urban areas

Urban agriculture,urban farming, or urban gardening is the practice of cultivating, processing and distributing food in or around urban areas. Urban agriculture can also involve animal husbandry, aquaculture, agroforestry, urban beekeeping, and horticulture. These activities occur in peri-urban areas as well, and peri-urban agriculture may have different characteristics.

The United Nations defines community development as "a process where community members come together to take collective action and generate solutions to common problems." It is a broad concept, applied to the practices of civic leaders, activists, involved citizens, and professionals to improve various aspects of communities, typically aiming to build stronger and more resilient local communities.

The Community Planning and Development agency within the United States Department of Housing and Urban Development (HUD) administers the grant programs that help communities plan and finance their growth and development, increase their capacity to govern, and provide shelter and services for homeless people. HUD is a national program, and HUD provides funding directly to larger cities and counties, and for smaller cities and counties, generally to state government. HUD's programs include the Community Development Block Grant Program and the HOME program.

Center for Neighborhood Technology non-profit organisation in the USA

The Center for Neighborhood Technology (CNT) is a non-profit organization, headquartered in Chicago, Illinois, which is committed to sustainable development and livable urban communities.

Community economic development (CED) is a field of study that actively elicits community involvement when working with government, and private sectors to build strong communities, industries, and markets.

In the United States, colonias are low-income, unincorporated, slum-areas, located along the Mexico–United States border region that began to emerge with the advent of informal housing. Colonias consist of peri-urban subdivisions of substandard housing lacking in basic services such as potable water, electricity, paved roads, proper drainage, and waste management. Often situated in geographically inferior locations, such as former agricultural floodplains, colonias suffer from associated issues like flooding. Furthermore, urbanization practices have amplified the issues, such as when developers strip topsoil from the ground in order to subdivide land, the resulting plains become breeding grounds for mosquitoes and disease. Traditional homeownership financing methods are rare amongst colonias residents, and therefore these areas consist of ramshackle housing units built incrementally with found material on expanses of undeveloped land. Colonias have a predominant Latino population where 85 percent of those Latinos under the age of 18 are United States citizens. The U.S. has viewed border communities as a place of lawlessness, poverty, backwardness, and ethnic difference.

The Furman Center for Real Estate and Urban Policy is a joint center at New York University School of Law and the NYU Wagner School of Public Service. The Furman Center was established in 1995 to create a place where people interested in affordable housing and land use issues could turn to for factual, objective research and information. Since that time, the Furman Center has become an authority on such matters in New York City. The Furman Center has a three-part mission, including providing objective academic research about land use, real estate, housing and urban affairs, with a particular focus on New York City, promoting intense debate and productive discussion among elected, academic, and industry leaders, and presenting essential data and analysis about the state of New York City's housing and neighborhoods.

The Chicago Metropolitan Agency for Planning (CMAP) is responsible for comprehensive regional planning in Cook, DuPage, Kane, Kendall, Lake, McHenry and Will counties in northeastern Illinois. The agency developed and now guides implementation of ON TO 2050, a new long-range plan to help the seven counties and 284 communities of northeastern Illinois implement strategies that address transportation, housing, economic development, open space, the environment, and other quality-of-life issues.

The Healthy Development Measurement Tool (HDMT), developed by the San Francisco Department of Public Health, provides an approach for evaluating land-use planning and urban development with regards to the achievement of human health needs. The HDMT provides a set of baseline data on community health metrics for San Francisco and development targets to assess the extent to which urban development projects and plans can improve community health. The HDMT also provides a range of policy and design strategies that can advance health conditions and resources via the development process.

Subsidized housing in the United States

Subsidized housing in the United States is administered by federal, state and local agencies to provide subsidized rental assistance for low-income households. Public housing is priced much below the market rate, allowing people to live in more convenient locations rather than move away from the city in search of lower rents. In most federally-funded rental assistance programs, the tenants' monthly rent is set at 30% of their household income. Now increasingly provided in a variety of settings and formats, originally public housing in the U.S. consisted primarily of one or more concentrated blocks of low-rise and/or high-rise apartment buildings. These complexes are operated by state and local housing authorities which are authorized and funded by the United States Department of Housing and Urban Development (HUD). More than 1.2 million households currently live in public housing of some type. Subsidized apartment buildings, often referred to as housing projects, have a complicated and often notorious history in the United States. While the first decades of projects were built with higher construction standards and a broader range of incomes and same applicants, over time, public housing increasingly became the housing of last resort in many cities. Several reasons have been cited for this negative trend including the failure of Congress to provide sufficient funding, a lowering of standards for occupancy, and mismanagement at the local level. Furthermore, housing projects have also been seen to greatly increase concentrated poverty in a community, leading to several negative externalities. Crime, drug usage, and educational under-performance are all widely associated with housing projects, particularly in urban areas.

Land recycling is the reuse of abandoned, vacant, or underused properties for redevelopment or repurposing.

Otis France Rolley was the seventh Director of Planning for the City of Baltimore, Maryland, serving from July 2003 until 2007. He was a Democratic candidate for mayor of Baltimore in 2011.

The California Sustainability Alliance is an organization funded by the California IOUs to bring together key stakeholders needed to overcome the obstacles of sustainability. The Alliance was designed in 2008 to help meet the State’s aggressive climate, energy and other resource and environmental goals by increasing and accelerating sustainable measures and strategies. The Alliance specifically focuses on energy efficiency, climate action, “smart growth” principles, renewable energy development, water-use efficiency, waste management, and transportation management within California.

Housing discrimination in the United States began after the abolition of slavery, typically as part of the "Jim Crow laws" that enforced racial segregation. The federal government began to take action against these laws in 1917, when the Supreme Court ruled in Buchanan v. Warley that ordinances prohibiting blacks from occupying or owning buildings in majority-white neighborhoods, and vice versa, were unconstitutional.

Urban agriculture in West Oakland

Urban agriculture in West Oakland involves the implementation of Urban agriculture in Oakland.

Environmental, ecological or green gentrification is a process in which cleaning up pollution or providing green amenities increases local property values and attracts wealthier residents to a previously polluted or disenfranchised neighbourhood. Green amenities include green spaces, parks green roofs, gardens and green and energy efficient building materials. These initiatives can heal many environmental ills from industrialization and beautify urban landscapes. Additionally, greening is imperative for reaching a sustainable future. However, if accompanied by gentrification, such initiatives can have an ambiguous social impact if the poor are displaced or forced to pay higher housing costs. First coined by Sieg et al. (2004), environmental gentrification is a relatively new concept, although it can be considered as a new hybrid of the older and wider topics of gentrification and environmental justice. Various studies have analyzed the social implications of greening projects specifically with regards to housing affordability and displacement of vulnerable citizens.
