human well-being |
A state of existence that fulfils various human needs, including material living conditions and quality of life, as well as the ability to pursue one's goals, to thrive, and feel satisfied with one's life (IPCC, 2020). The IPBES definition is consistent with this definition but notes that well-being also includes non-material living conditions and cultural identity. The phrase ‘Good quality of Life' as used in this report (see glossary entry) is intended to be inclusive of both the human well-being definitions given above.

Humanistic economics intend to show that humankind is perfectly capable of living without the profit motive, and has done so for most of its history. It goes again the tendency to consider the profit motive as self-evident, an idea that underlies many political decisions. See also Behavioural economics.

hydraulic fracturing |
An oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures. Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations.

Land degradation and restoration assessment |
hydrothermal vent |
A fissure on the floor of a sea out of which flows water that has been heated by underlying magma. The water can be as hot as 400°C (752°F) and usually contains dissolved minerals that precipitate out of it upon contact with the colder seawater, building a stack of minerals, or chimney. Hydrothermal vents form an ecosystem for microbes and animals, such as tube worms, giant clams, and blind shrimp, that can with stand the hostile environment. The hottest hydrothermal vents are called black smokers because they spew iron and sulfide which combine to form iron mono sulfide, a black compound.
|
Asia-Pacific assessment |
hypoxia |
Low dissolved oxygen levels in coastal and oceanic waters (<2mL per liter of water), either naturally occurring or as a result of a degradation (e.g. eutrophication).
|

observing |
Observing is defined as a non-extractive practice that is based on the observation of wild species. The observation can imply some interaction with the wild species, such as the activities of wildlife tourism and whale watching or no interaction with the wild species, such as photography.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.

old-growth forest |
From an ecological point of view, old-growth forests are a stage of forest development characterized by large/old trees and structural complexity including live and dead trees, and vertical and horizontal heterogeneity (including a multi-layered canopy). The structural diversity of old growth forests often supports distinctive/specialist biodiversity; large/old trees are keystone components of the ecosystem (Lindenmayer et al., 2012). In addition, the long-period of forest development without stand replacement disturbance allows many poor-dispersing species to accumulate (IUFRO, 2018). Other definitions can be found based on economic and social perspectives (Hilbert & Wienscczyk, 2007).

one biosecurity |
interdisciplinary approach to biosecurity policy and research that builds on the interconnections between human, animal, plant, and environmental health to effectively prevent and mitigate the impacts of invasive alien species. It provides an integrated perspective to address the many biosecurity risks that transcend the traditional boundaries of health, agriculture, and the environment. Individual invasive alien plant and animal species often have multiple impacts across sectors: as hosts of zoonotic parasites, vectors of pathogens, pests of agriculture or forestry, as well as threats to biodiversity and ecosystem function

|

one health |
an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals, and ecosystems. It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and interdependent (One Health High-Level Expert Panel

|
Americas assessment |
option value |
The potential ability to use some of nature’s benefits in the future, although they are not currently used, or the likelihood for their future use is low. It represents the willingness to preserve an option for the future enjoyment of nature’s benefits.

Scenarios and models assessment |
organic agriculture |
Any system that emphasizes the use of techniques such as crop rotation, compost or manure application, and biological pest control in preference to synthetic inputs. Most certified organic farming schemes prohibit all genetically modified organisms and almost all synthetic inputs. Its origins are in a holistic management system that avoids off-farm inputs, but some organic agriculture now uses relatively high levels of off-farm inputs.

organic farming |
Crop and livestock production using natural sources of nutrients (such as compost, crop residues, and manure) and natural methods of crop and weed control, instead of using synthetic or inorganic agrochemicals. Genetically modified organisms are not usually part of organic agriculture. It is also sometimes called low- input farming, but may involve high inputs of labour and be intensive in its practice.
