National income is the total value of all goods and services produced in an economy in a given year. (Rahman, Muhammad & Ulubasoglu, Mehmet. (2015). Economic Growth: Measurement. International Encyclopedia of the Social & Behavioral Sciences. 10.1016/B978-0-08-097086-8.71063-4.)
Note
National income is derived from gross national product by subtracting depreciation and adjusting for taxes and subsidies.
Areas of outstanding natural beauty, set aside for the conservation of flora, fauna and scenery, and for recreation, if this does not conflict with the conservation objectives of the parks and their landscapes. Hunting, logging, mining, commercial fishing, agriculture and livestock grazing are all controlled within national parks, as is industrial activity. (European Environment Agency, 2024. Glossary. )
In cuisine and commerce, particularly in France and Italy, the summer truffle (T. aestivum) is distinguished from the burgundy truffle (T. uncinatum). However, molecular analysis showed in 2004 that these two varieties of truffle are one species. The differences between them are therefore likely due to environmental factors
Drugs that are chemically similar to naturally occurring metabolites, but differ enough to interfere with normal metabolic pathways, (MeSH. 2025. Antimetabolites. https://meshb.nlm.nih.gov/record/ui?ui=D000963)
A serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure, vulnerability and capacity, leading to one or more of the following: human, material, economic and environmental losses and impacts. (United Nations Office for Disaster Risk Reduction (UNDRR). 2017. The Sendai Framework Terminology on Disaster Risk Reduction. "Disaster". Accessed 17 March 2026. https://www.undrr.org/terminology/disaster.)
Note
The effect of the disaster can be immediate and localized, but is often widespread and could last for a long period of time. The effect may test or exceed the capacity of a community or society to cope using its own resources, and therefore may require assistance from external sources, which could include neighbouring jurisdictions, or those at the national or international levels.
The areas where a species or other resource naturally exists in the world and the geographical representation of these areas. (Adapted from http://terim.tuba.gov.tr/)
Note
Natural distribution should not be confused with "normal distribution" <c_4ed623ba> or Gaussian distribution as frequency distribution.
The natural drying method consists essentially of exposing the substance or product to the air (in sun or shade). (Adapted from FAO, 1994. Agricultural engineering in development https://www.fao.org/4/T0522E/T0522E00.htm#)
An organism which lives at the expense of another organism in its area of origin and which may limit the population of that organism. This includes parasitoids, parasites, predators, phytophagous organisms and pathogens. (Adapted from IPPC Secretariat. 2021. Glossary of phytosanitary terms. International Standard for Phytosanitary
Measures No. 5. Rome. FAO on behalf of the Secretariat of the International Plant Protection
Convention.)
Aquatic animals that live within the benthos; the bottom substrate of a body of water; especially in soft sediments. (Waldbusser, G.G., Marinelli, R.L., Whitlatch, R.B. and Visscher, P.T. 2004. The effects of infaunal biodiversity on biogeochemistry of coastal marine sediments. Limnology and Oceanography 49: 1482-1492. )
Flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel. (FAOLEX. 2025. Glossary https://www.fao.org/faolex/)
Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. (https://en.wikipedia.org/wiki/Natural_history)
Pastures with uncultivated (not sown) natural or semi-natural grasses, herbs or shrubs used for grazing domestic livestock. (Adapted from British Columbia Ministry of Agriculture, 2017. Agricultural Land Use Inventory https://www.slrd.bc.ca/sites/default/files/pdfs/planning/squamish_ead_aluireport.pdf)
A naturally occurring, semi-synthetic or synthetic substance that kills or inhibits the replication of microorganisms. (FAO/WHO. 2022. Antimicrobial Resistance Terms, Joint FAO/WHO Centre (CODEX Food Standards and Zoonotic Diseases) (CJW). https://www.fao.org/3/cb9414en/cb9414en.pdf)
Renewal of trees by self-sown seeds or natural vegetative means. (Guidelines for the Restoration, Management and Rehabilitation of Degraded and Secondary Tropical Forests, ITTO, 2002.)
Any portion of the natural environment, such as air, water, soil, botanical and zoological resources and minerals. (FAO, 2024. FAOTERM. Natural resources https://www.fao.org/faoterm/en/)
Active management of the earth's natural resources and environment to ensure their quality is maintained and that they are wisely used. (GEMET, 2024. Nature conservation. http://www.eionet.europa.eu/gemet/concept/5537)
