Concept Definition Deliverable(s)
livelihood diversification

Livelihood diversification is defined as the process by which rural families construct a diverse portfolio of activities and social support capabilities in their struggle for survival and in order to improve their standards of living”.

Sustainable use assessment
livelihood resilience

The capacity of all people across generations to sustain and improve their livelihood opportunities and well-being despite environmental, economic, social and political disturbances.

Land degradation and restoration assessment
livelihood security

Adequate and sustainable access to income and resources to meet basic needs (including adequate access to food, potable water, health facilities, educational opportunities, housing, time for community participation and social integration).

Land degradation and restoration assessment
living in harmony with nature

Within the context of the IPBES Conceptual Framework - a perspective on good quality of life based on the interdependence that exists among human beings, other living species and elements of nature. It implies that we should live peacefully alongside all other organisms even though we may need to exploit other organisms to some degree.

Asia-Pacific assessment, Europe and Central Asia assessment, Africa assessment, Americas assessment, Sustainable use assessment, Scenarios and models assessment
local

adj. Referring to places, people, things or events within a short distance of an identified locality.

Pollination assessment
local communities

Local communities” refers to non-indigenous communities with historical linkages to places and livelihoods characterized by long- term relationships with the natural environment, often over generations.

Sustainable use assessment
local community

A group of individuals that interact within their immediate surroundings and/or direct mutual influences in their daily life. In this sense, a rural village, a clan in transhumance or the inhabitants of an urban neighbourhood can be considered a local community, but not all the inhabitants of a district, a city quarter or even a rural town. A local community could be permanently settled or mobile.

Pollination assessment
local ecological knowledge

Knowledge about nature, including organisms (animals and plants), ecosystems and ecological interactions, held by local people who interact with and use natural resources. This is a manifestation of indigenous local knowledge (ILK), but includes also knowledge held by those local people who may not be officially recognized as indigenous (in legal terms). Like traditional ecological knowledge, LEK can be seen as a knowledge-practice-belief complex. In other words, it is a cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission (Berkes, 2012). This encompasses ways of knowing and doing, which are dynamic concepts relying on building on experience and adapting to changes, thereby imbibe a strong learning-by-doing component.

Sustainable use assessment
local economies

Local economies and subsistence economies are defined as those that are small in scale and in which the use of resources (including wild species) are limited and exclusively used to meet local needs rather than accumulated or sold for profit.

Sustainable use assessment
logging

Logging is defined as the removal of whole trees or woody parts of trees from their habitat. Logging generally results in the death of the tree, but also includes cases in which it may not, such as coppicing. Logging occurs in forests that may be classified as primary, naturally regenerating, planted, and plantation. This assessment does not address logging from plantation forests except as it has bearing on the practice in the other forest types. Harvest of non-woody parts of trees ( leaves, propagules and bark) are here defined as gathering.

Sustainable use assessment
paired catchment

Paired catchment studies have been widely used to assess the likely impact of land use change on water yield around the world. Such studies involve the use of two catchments (drainage basins) with similar characteristics in terms of slope, aspect, soils, area, precipitation and vegetation located adjacent to each other. Following a calibration period, where both catchments are monitored, one of the catchments is subjected to treatment and the other remains as a control. This allows the climatic variability to be accounted for in the analysis. The change in water yield can then be attributed to changes in vegetation. The paired catchment studies reported in the literature can be divided into four broad categories: (i) afforestation experiments; (ii) regrowth experiments; (iii) deforestation experiments; and (iv) forest conversion experiments.

participatory method

Participatory research methods are a variety of qualitative and quantitative methods geared towards planning and conducting the research process with those people whose life-world and meaningful actions are under study (Bergold & Thomas, 2012). Participatory methods acknowledge the possibility, the significance, and the usefulness of involving research partners in the knowledge-production process (Bergold, 2007).

Sustainable use assessment
participatory scenario development (and planning)

Approaches characterised by more interactive, and inclusive, involvement of stakeholders in the formulation and evaluation of scenarios. Aimed at improving the transparency and relevance of decision-making, by incorporating demands and information of each stakeholder, and negotiating outcomes between stakeholders.

pathways

“Pathways” consist of descriptions of different strategies for moving from the current situation towards a desired future vision or set of specified targets. They are descriptions of purposive courses of actions that build on each other, from short-term to long-term actions into broader transformation. They are closely related to normative or policy or target-seeking scenarios.

Global assessment (1st work programme)
payment for ecosystem services

Payments for Ecosystem Services (PES) are a specific class of approach, used to facilitate voluntary transaction between a provider and a user of a service, conditioned on natural resource management rules for dealing with environmental externalities. PES is created to deal with market failures, environmental externalities, property rights problems and asymmetric information between economic actors.

Sustainable use assessment
payment for ecosystem services

Voluntary transactions that generate offsite services and are established to enable service users to pay resource providers for the conditional provision of the desired ecosystem service.

Americas assessment
payment for ecosystem services

A payment mechanism that involves a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-and-above what would otherwise be provided in the absence of payment.

payment for ecosystem services

Payments for ecosystem services (PES) is a term used to describe a process whereas a beneficiary or user of an ecosystem service makes a direct or indirect payment to a provider of that service. PES involve a series of payments to land or other natural resource owners in return for a guaranteed flow of ecosystem services or certain actions likely to enhance their provision over-¬and-above what would otherwise be provided in the absence of payment.

peatland

Wetlands which accumulate organic plant matter in situ because waterlogging prevents aerobic decomposition and the much slower rate of the resulting anaerobic decay is exceeded by the rate of accumulation.
