Concept Definition Deliverable(s)
fallow

Land normally used for production and left to recover for part or all of a growing season (more in the case of swidden agriculture).

Sustainable use assessment, Global assessment (1st work programme)
family forestry

Family forestry is forest tenure and activities by persons with ownership or tenure rights to forest land. Persons owning or managing forests often include the whole family in the activities and the forest land goes from one generation to the next.

Global assessment (1st work programme)
farm

An area of land, a holding of any size from a small plot or garden (fractions of a hectare) to several thousand hectares that is devoted primarily to agriculture to produce food, fibre, or fuel. A farm may be owned and operated by an individual, family, community, corporation or a company, and may produce one to many types of produce or animal.

Pollination assessment
feedback

The modification or control of a process or system by its results or effects.

Sustainable use assessment, Americas assessment, Europe and Central Asia assessment, Asia-Pacific assessment, Africa assessment
feedback loops

processes that either amplify (positive feedback loop) or diminish (negative feedback loop) the effects of a biological invasion. Feedback loops may make the impacts of biological invasions stronger or weaker, starting a chain reaction that repeats again and again. Negative feedback loop: A human-natural feedback that continually stabilizes or reduces ongoing or future biological invasions (also known as a ‘balancing’ feedback loop). Positive feedback loop: A human-natural feedback that continually increases ongoing or future biological invasions (also known as ‘exacerbating’ or ‘reinforcing’ feedback loops)

Invasive alien species assessment
feral

Species are considered to be feral if they or their ancestors were formerly domesticated, but they are now living independently of humans.

Sustainable use assessment
field

In agriculture, it is a defined area of cleared enclosed land used for cultivation or pasture.

Pollination assessment
fire regime

A term used to describe the characteristics of fires that occur in a particular ecosystem over a period of time. Fire regimes are characterized based on a combination of factors including the frequency, intensity, size, pattern, season and severity of fires.

Land degradation and restoration assessment
fire-stick farming

The practice of indigenous Australians to use fire to burn vegetation to facilitate hunting and to change the composition of the plant and animal species of an area. It was coined by Australian archaeologist Rhys Jones.

Asia-Pacific assessment
fishery

A unit determined by an authority or other entity that is engaged in raising and/or harvesting fish. Typically, the unit is defined in terms of some or all of the following: people involved, species or type of fish, area of water or seabed, method of fishing, class of boats and purpose of the activities.

Global assessment (1st work programme)
fishery

Generally, a fishery is an activity leading to harvesting of fish. It may involve capture of wild fish or raising of fish through aquaculture. Note that in this definition, the term fish includes all types of marine animals, fish, but also crustaceans, mollusks, echinoderms etc.

Sustainable use assessment
fishing

Fishing is defined as the removal from their habitats of aquatic animals (vertebrates and invertebrates) that spend their full life cycle in water (fish, some marine mammals, shellfish, shrimps, squids, corals). Fishing most often results in the death of the aquatic animal, but it may not in some cases. To reflect both situations, fishing has been sub-divided into a lethal and a “non-lethal” category. Lethal fishing is defined as the general and more usual meaning of fishing that leads to the killing of the animal, such as in traditional commercial fisheries. “Non-lethal fishing is defined as the temporary or permanent capture of live animals from their habitat without intended mortality, such as in aquarium fish trade or catch and release. However, unintended mortality may occur in “non-lethal” fishing and the term “non-lethal” is therefore put in quotes. The killing of species that spend part of their life cycle in terrestrial environments (e.g. walrus, sea turtles) is encompassed by the definition of hunting.

Sustainable use assessment
fitness (ecology)

Fitness involves the ability of organisms- or populations or species- to survive and reproduce in the environment in which they find themselves, and thus contribute genes to the next generation (Orr, 2009).

Asia-Pacific assessment
flower strip

Linear areas of land within or at the edges of fields, farms, or other areas (rights of way, riparian areas, etc.) where flowering plants are seeded and encouraged to grow, often for the benefit of pollinators and other wildlife (q.v. insectory strips).

Pollination assessment
flower-visitor

An animal that visits flowers (a.k.a. anthophile) but is not necessarily a pollinator.

Pollination assessment
flowering plant

Plants that are characterized by producing flowers, even if inconspicuous. They are collectively called Angiosperms and include most plants grown for food and fibre.

food sovereignty

Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems.

Pollination assessment
food sovereignty (paradigm)

The right to define own policies and strategies for the sustainable production, distribution and consumption of food that guarantee the right to food for the entire population, on the basis of small and medium-sized production, respecting their own cultures and the diversity of peasant, fishing and indigenous forms of agricultural production, marketing and management of rural areas, in which women play a fundamental role.

Land degradation and restoration assessment
food web

An important ecological concept representing feeding relationships within a community and implying the transfer of food energy from its source in plants through herbivores to carnivores; normally, food webs consist of a number of food chains meshed together.

functional redundancy

The occurrence in the same ecosystem of species filling similar roles, which results in a sort of insurance in the ecosystem, with one species able to replace a similar species from the same functional niche.

Global assessment (1st work programme)
functional trait

A feature of an organism, which has demonstrable links to the organism's function (Lavorel et al. 1997). As such, a functional trait determines the organism's response to pressures (Response trait), and/or its effects on ecosystem processes orservices(Effect trait).Functional traits are considered as reflecting adaptations to variation in the physical and biotic environment and trade-offs (ecophysiological and/or evolutionary) among different functions within an organism. In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits, including demographic traits(at population level). In animals, these traits are combined with lifehistory and behavioural traits (e.g. guilds, organisms that use similar resources/ habitats).

Asia-Pacific assessment
functional trait

Any feature of an organism, expressed in the phenotype and measurable at the individual level, which has demonstrable links to the organism's function. As such, a functional trait determines the organism's response to external abiotic or biotic factors (response trait), and/or its effects on ecosystem properties or benefits or detriments derived from such properties (effect trait). In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits. In animals, these traits include e.g. body size, litter size, age of sexual maturity, nesting habitat, time of activity.
