Invasive alien species assessment |
extinction |
A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally ( extinction of all populations in a country, continent or ocean) or globally. Populations or species reduced to such low numbers that they are no longer of economic or functional importance may be said to have gone economically or functionally extinct, respectively. Species extinctions are typically not documented immediately: for example, the IUCN Red List categories and criteria require there to be no reasonable doubt that all individuals have died, before a species is formally listed as Extinct (see IUCN Red List).
|
Sustainable use assessment |
extinction debt |
The future extinction of species due to events in the past, owing to a time lag between an effect such as habitat destruction or climate change, and the subsequent disappearance of species.

extractive practice |
Extractive practices are defined as the temporary or permanent removal of organisms, part of them or materials derived from them, and may result in mortality of the individual to be used (hunting or whole plant harvest), but does not necessarily do so (e.g. limited collection of plant propagules or shearing and releasing of vicuna).

malnutrition |
Malnutrition refers to deficiencies, excesses or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition covers 2 broad groups of conditions. One is ‘undernutrition’—which includes stunting (low height for age), wasting (low weight for height), underweight (low weight for age) and micronutrient deficiencies or insufficiencies (a lack of important vitamins and minerals). The other is overweight, obesity and diet-related noncommunicable diseases (such as heart disease, stroke, diabetes and cancer).

managed pollinator |
A kind of pollinator that is maintained by human beings through husbandry (e.g. some honey bees, some leafcutting and orchard bees, some bumble bees). The terms can be broadened to include wild pollinators (q.v.) that flourish by human encouragement.

Pollination assessment |
management |
for the purpose of the assessment, any action taken to address the threats, risks, distribution, abundance and impacts of an invasive alien species within a defined geographic area (Hulme, 2006; Pyšek et al., 2020). Management includes prevention, preparedness, eradication, containment, and control
|
Invasive alien species assessment |
management of wild species |
The management of wild species is the management process influencing interactions among and between wild species, its habitats and humans to achieve predefined impacts valued by stakeholders. It attempts to balance the needs of wild species and the preservation of the ecosystems they inhabit with the needs of humans, using the best available sources of knowledge.

mangrove |
Group of trees and shrubs that live in the coastal intertidal zone. Mangrove forests only grow at tropical and subtropical latitudes near the equator because they cannot withstand freezing temperatures.

marginal lands |
Land having limitations which in aggregate are severe for sustained application of a given use. On these lands, options are limited for diversification without the use of inputs; inappropriate management of lands may cause irreversible degradation.

marginalization |
Marginalization refers to the set of processes through which some individuals and groups face systematic disadvantages in their interactions with dominant social, political and economic institutions. The disadvantages arise from class status, social group identity (kinship, ethnicity, caste and race), political affiliation, gender, age and disability.
|
Global assessment (1st work programme) |
marginalization |
Marginalisation is a complex and multidimensional concept, which simply cannot be seen as a state of being ( a condition of low income or food insecurity) but needs to be considered a process over time with several inter-related elements interacting with social and economic conditions, political standing, and environmental health. A full understanding of the term marginalisation needs to be based on the view that the best judge of poverty and marginalisation are the people experiencing it.
|
Sustainable use assessment |
marginalized community |
Marginalized communities, peoples or populations are groups and communities that experience discrimination and exclusion (social, political and economic) because of unequal power relationships across economic, political, social and cultural dimensions (National Collaborating Centre for Determinants of Health.

microevolution |
A change in gene frequency within a population. Evolution at this scale can be observed over short periods of time - for example, between one generation and the next, the frequency of a gene for pesticide resistance in a population of crop pests increases. Such a change might come about because natural selection favored the gene, because the population received new immigrants carrying the gene, because some nonresistant genes mutated to the resistant version, or because of random genetic drift from one generation to the next.
