Concept Definition Deliverable(s)
nature’s contributions to people

All the contributions, both positive and negative, of living nature (i.e. all organisms, ecosystems, and their associated ecological and evolutionary processes) to people’s quality of life. Beneficial contributions include e.g. food provision, water purification, flood control, and artistic inspiration, whereas detrimental contributions include e.g. disease transmission and predation that damages people or their assets. NCP may be perceived as benefits or detriments depending on the cultural, temporal or spatial context (Díaz et al., 2018). IPBES considers a gradient of approaches to NCP, ranging from a purely generalizing approach to a purely context-specific one. Within the generalizing approach, IPBES identifies 18 categories of NCP, organized in three partially overlapping groups: Material contributions are substances, objects or other material elements from nature that directly sustain people’s physical existence and material assets. They are typically physically consumed in the process of being experienced, for example when organisms are transformed into food, energy, or materials for clothing, shelter or ornamental purposes. Non-material contributions are nature’s effects on subjective or psychological aspects underpinning people’s quality of life, both individually and collectively. Examples include forests and coral reefs providing opportunities for recreation and inspiration, or particular organism (animals, plants, fungi) or habitat (mountains, lakes) being the basis of spiritual or social-cohesion experiences. Regulating contributions are functional and structural aspects of organisms and ecosystems that modify environmental conditions experienced by people, and/or regulate the generation of material and non- material contributions. Regulating contributions frequently affect quality of life in indirect ways. For example, people directly enjoy useful or beautiful plants, but only indirectly the soil organisms that are essential for the supply of nutrients to such plants.

Global assessment (1st work programme)
nature’s contributions to people

All the contributions, both positive and negative, of nature (i.e. biodiversity, ecosystems, and their associated ecological and evolutionary processes) to good quality of life for humanity. The positive contributions from nature (benefits) include such things as food provision, water purification, and artistic inspiration, whereas negative contributions (detriments), include e.g. pathogens, disease vectors, or predation that damage people, their built infrastructure, or their domesticated animals and plants. While some NCP are considered exclusively positive or negative, many NCP may be perceived as benefits or detriments depending on the cultural context.

Asia-Pacific assessment
nature’s contributions to people

All the contributions, both positive and negative, of living nature (i.e. diversity of organisms, ecosystems, and their associated ecological and evolutionary processes) to the quality of life of people. This is the core IPBES definition (which is used by IPCC in AR6 Special Reports). The IPBES definition goes on to elaborate as follows: “Beneficial contributions from nature include such things asfood provision, water purification, flood control, and artistic inspiration, whereas detrimental contributions include disease transmission and predation that damages people or their assets. Many NCP may be perceived as benefits or detriments depending on the cultural, temporal or spatial context.” The creation of a new term to supersede ecosystem services had several justifications. First, the original ecosystem services definition went on to define four subtypes (provisioning, cultural, regulatory and supporting), but practitioners recognized that many services fit into more than one of the four categories. Secondly, IPBES wished to make explicit that positive and negative effects were included. Thirdly, the term ‘services’ had its origin in economics, which was perceived in some worldviews to be too narrow a formulation of the relationships between nature and people. The new language is considered more inclusive.

nature’s non-material benefits

Benefits from nature that do not take a physical form such as spiritual enrichment, intellectual development, recreation and aesthetic values.

Land degradation and restoration assessment
ncp (potential)

The capacity of an ecosystem to provide NCP (see Chapter 2.3).

Global assessment (1st work programme)
ncp (realized)

The actual flow of NCP that humanity receives. Realized NCP typically depends not only on potential NCP but also anthropogenic assets (e.g. boats and fishing gear, or farm equipment), human labor, and institutions. Institutions can facilitate or prevent.

near surface ozone

Ozone near the earth surface formed photochemically during the oxidation of hydrocarbons in the presence of nitrogen oxides.

Land degradation and restoration assessment
neo-endemic taxa

Recently diverged taxa that are endemic because of lack of dispersal/migration out of their ancestral area, as opposed to paleo-endemic taxa that were perhaps more widespread in the past and are now restricted to a local region (Mishler et al., 2014).

Global assessment (1st work programme)
nested (in plant-pollinator networks (q.v.))

The degree to which species (plants or pollinators) with few interaction links share a sub-set of the links of other species, rather than having a different set of links. In highly nested networks, groups of species that share more or less similar activities contain both generalist species (q.v.) (i. e., with many links) and specialist species (q.v.) (i. e., with few links, but shared with the generalists). In mutualistic networks, such as pollination, nestedness is often asymmetrical (q.v.), with specialists of one group (plants or pollinators) linked to the generalists of the partner group (pollinators or plants).

Pollination assessment
net biome production

The amount of carbon accumulating or lost in ecosystems at the regional scale is the Net Biome Production (NBP), defined as the NEP corrected for lateral transfers of carbon to adjacent biomes, due to process such as trade in agricultural products, export of organic matter in rivers and losses due to disturbances, including land clearing and wildfire.

Land degradation and restoration assessment
net ecosystem production

The amount of NPP left in the ecosystem after the additional respiration by microbes and animals is the Net Ecosystem Production (NEP).

net primary production

The difference between how much CO2 vegetation takes in during photosynthesis (gross primary production) minus how much CO2 the plants release during respiration (NASA Earth Observatory, 2018). It corresponds to the increase in plant biomass or carbon of.

net primary production

The total mass of carbon taken out of the atmosphere by plant photosynthesis (Gross Primary Production) minus return to the atmosphere of carbon due to autotrophic respiration.

Land degradation and restoration assessment
network governance

A network is an informal arrangement where two or more autonomous individuals and/or organizations come together to exchange ideas, build relationships, identify common interests, explore options on how to work together, share power, and solve problems of mutual interest. Network governance commonly emerges when people realize that they cannot solve a particular problem or issue by working independently and that the only way to achieve their interests is by actively collaborating. Network governance varies in terms of objectives, spatial scales, leadership, representation, organization, and complexity. It is designed to supplement, not replace, other forms of natural resource governance.

Americas assessment
nexus

A perspective which emphasizes the inter-relatedness and interdependencies of ecosystem components and human uses, and their dynamics and fluxes across spatial scales and between compartments. Instead of just looking at individual components, the functioning, productivity and management of a complex system is taken into consideration. In such complex systems there are trade-offs as well as facilitation and amplification between the different components. A nexus approach can help address synergies and trade-offs among multiple sectors and among various Sustainable Development Goals and biodiversity targets simultaneously (adapted from UNU-FLORES, 2018; also see Chapter 5).

Sustainable use assessment
niche model

Also known as species distribution models, niche models predict the spatial distribution of a species as a function of environmental variables. They are often used to project the future distributions of species in response to climate change.

non-extractive practices

Non-extractive practices are defined as practices based on the observation of wild species in a way that does not involve the harvest or removal of any part of the organism. The observation can imply some interaction with the wild species, such as the activities of wildlife and whale watching or no interaction with the wild species, such as remote photography.

non-lethal harvest

Non-lethal harvest is defined as the temporary or permanent capture of live animals from their habitat without mortality, such as for the aquarium trade, pet trade or zoos, tag and release activities. Non-lethal harvest of animals also includes the parts or products of animals that do not lead to the mortality of the host, such as vicuna fiber, swift nests or wild honey.

Sustainable use assessment
non-linear

Not arranged in a straight line, not sequential or straightforward.

Asia-Pacific assessment
