A park is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. Many parks have fields for playing sports such as baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue grills.
The term built environment refers to human-made conditions and is often used in architecture, landscape architecture, urban planning, public health, sociology, and anthropology, among others. These curated spaces provide the setting for human activity and were created to fulfill human desires and needs. The term can refer to a plethora of components including the traditionally associated buildings, cities, public infrastructure, transportation, open space, as well as more conceptual components like farmlands, dammed rivers, wildlife management, and even domesticated animals.
Urban agriculture refers to various practices of cultivating, processing, and distributing food in urban areas. The term also applies to the area activities of animal husbandry, aquaculture, beekeeping, and horticulture in an urban context. Urban agriculture is distinguished from peri-urban agriculture, which takes place in rural areas at the edge of suburbs.
Urban forestry is the care and management of single trees and tree populations in urban settings for the purpose of improving the urban environment. Urban forestry involves both planning and management, including the programming of care and maintenance operations of the urban forest. Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Urban foresters plant and maintain trees, support appropriate tree and forest preservation, conduct research and promote the many benefits trees provide. Urban forestry is practiced by municipal and commercial arborists, municipal and utility foresters, environmental policymakers, city planners, consultants, educators, researchers and community activists.
An urban park or metropolitan park, also known as a city park, municipal park, public park, public open space, or municipal gardens (UK), is a park or botanical garden in cities, densely populated suburbia and other incorporated places that offers green space and places for recreation to residents and visitors. Urban parks are generally landscaped by design, instead of lands left in their natural state. The design, operation and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company.
A community garden is a piece of land gardened or cultivated by a group of people individually or collectively. Normally in community gardens, the land is divided into individual plots. Each individual gardener is responsible for their own plot and the yielding or the production of which belongs to the individual. In collective gardens the piece of land is not divided. A group of people cultivate it together and the harvest belongs to all participants. Around the world, community gardens exist in various forms, it can be located in the proximity of neighborhoods or on balconies and rooftops. Its size can vary greatly from one to another.
Urban gardening is the practice of growing vegetables, fruit and plants in urban areas, such as schools, backyards or apartment balconies.
In urban planning, infill, or in-fill, is the rededication of land in an urban environment, usually open-space, to new construction. Infill also applies, within an urban polity, to construction on any undeveloped land that is not on the urban margin. The slightly broader term "land recycling" is sometimes used instead. Infill has been promoted as an economical use of existing infrastructure and a remedy for urban sprawl. Detractors view increased urban density as overloading urban services, including increased traffic congestion and pollution, and decreasing urban green-space. Many also dislike it for social and historical reasons, partly due to its unproven effects and its similarity with gentrification.
Urban prairie is vacant urban land that has reverted to green space. The definition can vary across countries and disciplines, but at its broadest encompasses meadows, lawns, and gardens, as well as public and private parks, vacant land, remnants of rural landscapes, and areas along transportation corridors. If previously developed, structures occupying the urban lots have been demolished, leaving patchy areas of green space that are usually untended and unmanaged, forming an involuntary park. Spaces can also be intentionally created to facilitate amenities, such as green belts, community gardens and wildlife reserve habitats.
Philadelphia Green, a program of the Pennsylvania Horticultural Society, is a large urban greening program that serves southeastern Pennsylvania. Since 1974, Philadelphia Green has supported the development and ongoing care of community gardens, neighborhood parks, and public green spaces in Philadelphia.
Shrinking cities or urban depopulation are dense cities that have experienced a notable population loss. Emigration is a common reason for city shrinkage. Since the infrastructure of such cities was built to support a larger population, its maintenance can become a serious concern. A related phenomenon is counterurbanization.
Urban horticulture is the science and study of the growing plants in an urban environment. It focuses on the functional use of horticulture so as to maintain and improve the surrounding urban area. Urban horticulture has seen an increase in attention with the global trend of urbanization and works to study the harvest, aesthetic, architectural, recreational and psychological purposes and effects of plants in urban environments.
Green infrastructure or blue-green infrastructure refers to a network that provides the “ingredients” for solving urban and climatic challenges by building with nature. The main components of this approach include stormwater management, climate adaptation, the reduction of heat stress, increasing biodiversity, food production, better air quality, sustainable energy production, clean water, and healthy soils, as well as more anthropocentric functions, such as increased quality of life through recreation and the provision of shade and shelter in and around towns and cities. Green infrastructure also serves to provide an ecological framework for social, economic, and environmental health of the surroundings. More recently scholars and activists have also called for green infrastructure that promotes social inclusion and equity rather than reinforcing pre-existing structures of unequal access to nature-based services.
Karl Linn was an American landscape architect, psychologist, educator, and community activist, best known for inspiring and guiding the creation of "neighborhood commons" on vacant lots in East Coast inner cities during the 1960s through 1980s. Employing a strategy he called "urban barnraising," he engaged neighborhood residents, volunteer professionals, students, youth teams, social activists, and community gardeners in envisioning, designing, and constructing instant, temporary, and permanent gathering spaces in neighborhoods, on college campuses, and at sites of major conferences and events. "Linn is considered 'Father of American Participatory Architecture' by many academic colleagues and architectural and environmental experts of the National Endowment for the Arts."
A neighborhood commons is a shared community space where neighborhood residents can come together to celebrate life, and young and old can be in each other’s presence but not in each other’s way. It can be a small-scale, multi-use facility, combining a sitting area, tot lot, playground, park, and community garden, designed and constructed on one or more vacant lots by residents, volunteer professionals, and youth work teams.
In land-use planning, urban green spaces are open-space areas reserved for parks and other "green spaces", including plant life, water features – also referred to as blue spaces – and other kinds of natural environment. Most urban open spaces are green spaces, but occasionally include other kinds of open areas. The landscape of urban open spaces can range from playing fields, to highly maintained environments, to relatively natural landscapes.
Community Greens, sometimes referred to as backyard commons, urban commons, or pocket neighborhoods, are shared open green spaces on the inside of city blocks, created either when residents merge backyard space or reclaim underutilized urban land such as vacant lots and alleyways. These shared spaces are communally used and managed only by the residents whose homes abut them. They are not a public park, a private backyard, or a community garden; however, they can function as all three.
Estella Diggs Park is a 0.9-acre (0.36 ha) public park in the Morrisania neighborhood of the Bronx, New York City. It was built on one of many vacant lots in Morrisania that resulted after some of the neighborhood's buildings were abandoned and demolished in the 1960s. The New York City Parks Department acquired this property in 1978 and it was briefly used as a community garden but later became vacant again. At the time, community organizer Megan Charlop led a protest effort against the movie Fort Apache, The Bronx arguing that it negatively depicted the neighborhood. As a compromise, the producers issued a $15,000 check to the fledgling Rock Greening Association, a community land trust Charlop had helped establish to acquire the empty lot where filming took place. The lot was then given to the city. In 1990, additional lots were acquired by Parks and the site was named Rocks and Roots Park.
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, these initiatives can have an ambiguous social impact. For example, if the low income households 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. Social implications of greening projects specifically with regards to housing affordability and displacement of vulnerable citizens. Greening in cities can be both healthy and just.
An urban meadow is a meadow which is influenced both by the environmental conditions of a city and the aesthetic and social needs of its residents. This differs from other meadow types as it is a highly engineered, novel, and site-specific designed landscape as well as an example of a nature-based solution (NBS).
