Park in the context of Time Landscape

The Imperial Palace (皇居, Kōkyo; lit. 'Imperial Residence') is the main residence of the emperor of Japan. It is a large park-like area located in the Chiyoda district of the Chiyoda ward of Tokyo and contains several buildings including the Fukiage Palace (吹上御所, Fukiage gosho) where the emperor has his living quarters, the main palace (宮殿, Kyūden) where various ceremonies and receptions take place, some residences of the Imperial Family, an archive, museums and administrative offices.

The 1.15-square-kilometer (0.44 sq mi) palace grounds and gardens are built on the site of the old Edo Castle.

Public works are a broad category of infrastructure projects, financed and procured by a government body for recreational, employment, and health and safety uses in the greater community. They include public buildings (municipal buildings, schools, and hospitals), transport infrastructure (roads, railroads, bridges, pipelines, canals, ports, and airports), public spaces (public squares, parks, and beaches), public services (water supply and treatment, sewage treatment, electrical grid, and dams), environmental protection (drinking water protection, soil erosion reduction,wildlife habitat preservation, preservation and restoration of forests and wetlands) and other, usually long-term, physical assets and facilities. Though often interchangeable with public infrastructure and public capital, public works does not necessarily carry an economic component, thereby being a broader term. Construction may be undertaken either by directly employed labour or by a private operator.

Public works has been encouraged since antiquity. The Roman emperor Nero encouraged the construction of various infrastructure projects during widespread deflation.

Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (freshwater or marine), but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, longlining, jigging, hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning.

The term fishing is also used more broadly to include catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations (fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead.

A sanitation worker (or sanitary worker) is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain. This is the definition used in the narrower sense within the WASH sector. More broadly speaking, sanitation workers may also be involved in cleaning streets, parks, public spaces, sewers, stormwater drains, and public toilets. Another definition is: "The moment an individual's waste is outsourced to another, it becomes sanitation work." Some organizations use the term specifically for municipal solid waste collectors, whereas others exclude the workers involved in management of solid waste (rubbish, trash) sector from its definition.

Sanitation workers are essential in maintaining safe sanitation services in homes, schools, hospitals, and other settings and protecting public health but face many health risks in doing so, including from exposure to a wide range of biological and chemical agents. Additionally, they may be at risk of injury from heavy labor, poor and prolonged postures and positions and confined spaces, as well as psychosocial stress. These risks are exacerbated under conditions of poverty, illness, poor nutrition, poor housing, child labor, migration, drug and alcohol abuse, discrimination, social stigma and societal neglect. In many developing countries, sanitation workers are "more vulnerable due to unregulated or unenforced environmental and labor protections, and lack of occupational health and safety".

A green belt or greenbelt is a policy, and land-use zone designation used in land-use planning to retain areas of largely undeveloped, wild, or agricultural land surrounding or neighboring urban areas. Similar concepts are greenways or green wedges, which have a linear character and may run through an urban area instead of around it. In essence, a green belt is an invisible line designating a border around a certain area, preventing development of the area and allowing wildlife to return and be established.

The more general term in the United States is green space or greenspace, which may be a very small area such as a park.

A public space is a place that is open and accessible to the general public. Roads, pavements, public squares, parks, and beaches are typically considered public space. To a limited extent, government buildings which are open to the public, such as public libraries, are public spaces, although they tend to have restricted areas and greater limits upon use. Although not considered public space, privately owned buildings or property visible from sidewalks and public thoroughfares may affect the public visual landscape, for example, by outdoor advertising. Recently, the concept of shared space has been advanced to enhance the experience of pedestrians in public space jointly used by automobiles and other vehicles.

Public space has also become something of a touchstone for critical theory in relation to philosophy, urban geography, visual art, cultural studies, social studies and urban design. The term 'public space' is also often misconstrued to mean other things such as 'gathering place', which is an element of the larger concept of social space. Public spaces have often been valued as democratic spaces of congregation and political participation, where groups can vocalize their rights.

An urban park or metropolitan park, also known as a city park, municipal park (North America), 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.

Depending on size, budget, and land features, which varies considerably among individual parks, common features include playgrounds, gardens, hiking, running, fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, performance venues, or BBQ and picnic facilities. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provides multiple benefits.

In land-use planning, urban green spaces are open-space areas reserved for parks and other spaces of greenery. These include plant life, water features – also known as blue spaces – and other kinds of natural environments. Most urban open spaces are green spaces, though some may consist of other types of open areas. The landscape of urban open spaces can range from playing fields and other highly maintained environments to more natural landscapes that appear less managed.

Urban green spaces may also include areas that are not publicly accessible, such as privately owned higher education campuses, school sports fields, allotments, neighborhood or community parks and gardens, and corporate campuses. Areas outside city boundaries, such as state and national parks or rural open spaces, are not generally considered urban open spaces. Boulevards, piazzas, plazas, and urban squares are not consistently classified as urban open spaces in land-use planning.

State parks are parks or other protected areas managed at the sub-national level within those nations which use "state" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, some of the Mexican states, and in Brazil. The term is also used in the Australian states of Victoria and New South Wales. The equivalent term used in Canada, Argentina, South Africa, and Belgium, is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.

State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as Anza-Borrego Desert State Park in California, Wood-Tikchik State Park in Alaska, or Adirondack State Park in New York, the largest state park in the United States.

A provincial park (or territorial park) is a park administered by one of the provinces of a country, as opposed to a national park. They are similar to state parks in other countries. They are typically open to the public for recreation. Their environment may be more or less strictly protected.

A ranger, park ranger, park warden, field ranger, or forest ranger is a person entrusted with protecting and preserving parklands and protected areas – private, national, state, provincial, or local parks. Their duties include (but are not limited to) law enforcement, wildlife and land management, community engagement and education, recreation area maintenance, and firefighting. Rangers monitor wildlife, remove snares, confront and arrest poachers, identify and remove invasive species, and much more.

A weed is a plant considered undesirable in a particular situation, growing where it conflicts with human preferences, needs, or goals. Plants with characteristics that make them hazardous, aesthetically unappealing, difficult to control in managed environments, or otherwise unwanted in farm land, orchards, gardens, lawns, parks, recreational spaces, residential and industrial areas, may all be considered weeds. The concept of weeds is particularly significant in agriculture, where the presence of weeds in fields used to grow crops may cause major losses in yields. Invasive species, plants introduced to an environment where their presence negatively impacts the overall functioning and biodiversity of the ecosystem, may also sometimes be considered weeds.

Taxonomically, the term "weed" has no botanical significance, because a plant that is a weed in one context, is not a weed when growing in a situation where it is wanted. Some plants that are widely regarded as weeds are intentionally grown in gardens and other cultivated settings. For this reason, some plants are sometimes called beneficial weeds. Similarly, volunteer plants from a previous crop are regarded as weeds when growing in a subsequent crop. Thus, alternative nomenclature for the same plants might be hardy pioneers, cosmopolitan species, volunteers, "spontaneous urban vegetation," etc.

Guandu Nature Park, also known as Kuantu Nature Park, (traditional Chinese: 關渡自然公園; simplified Chinese: 关渡自然公园; pinyin: Guāndù Zìrán Gōngyuán) is a park in Beitou District, Taipei, Taiwan.

A memorial is an object or place which serves as a focus for the memory or the commemoration of something, usually an influential, deceased person or a historical, tragic event. Popular forms of memorials include landmark objects such as homes or other sites, or works of art such as sculptures, statues, fountains or parks. Larger memorials may be known as monuments.

A sculpture garden or sculpture park is an outdoor garden or park which includes the presentation of sculpture, usually several permanently sited works in durable materials in landscaped surroundings.

A sculpture garden may be private, owned by a museum and accessible freely or for a fee, or public and accessible to all. Some cities own large numbers of public sculptures, some of which they may present together in city parks.
