customary land tenure

customary law / norms

Law consisting of customs that are accepted as legal requirements or obligatory rules of conduct; practices and beliefs that are so vital and intrinsic a part of a social and economic system that they are treated as if they were laws.

customary rights

customary sustainable use

decision context

The characteristics and needs of any particular policy or decision-making process.

decision support tools

Approaches and techniques based on science and other knowledge systems, including indigenous and local knowledge, that can inform, assist and enhance relevant decisions, policy-making and implementation at the local, national, regional and international levels.

decision uncertainty

Variation in subjective human judgments, preferences, beliefs, world views (Section 1.6.3).

decision-making

The process of making decisions can happen at the individual level or amongst groups and entails the prioritisation of certain values. This prioritization greatly influences which issues are found worthy of consideration, do and do not become part of the agenda, as well as determine which decision-makers are considered socially legitimate to participate in the process.

decision-making framework

System for logical interpretation of evidence leading to decision options that can be objectively evaluated.

decomposition

Breakdown of complex organic substances into simpler molecules or ions by physical, chemical and/or biological processes.

decorative and aesthetic uses

Decorative and aesthetic uses are defined as the uses of wild species in order to produce handicrafts and objects of adornment, beauty, and/or entertainment.

deflation (wind)

Wind erosion.

deforestation_1

Human-induced conversion of forested land to non-forested land. Deforestation can be permanent, when this change is definitive, or temporary when this change is part of a cycle that includes natural or assisted regeneration.

degraded land

Land in a state that results from persistent decline or loss of biodiversity and ecosystem functions and services that cannot fully recover unaided.

degraded lands

degrowth

Started as an activist movement around 2008 and turned into an academic discipline, it starts from the premise that economic growth cannot be sustained ad infinitum on a resource constraint planet. It demands a deep societal change, denying the need for economic growth. It is unclear whether degrowth should be considered as a collectively consented choice or an environmentally-imposed inevitability.

degrowth (or downscaling)

A theoretical frame invoking the necessity of downscaling and re- localizing production.

demographic change

A model describing transition in demographic profile of a population, which has been associated with the development process that transforms an agricultural society into an industrial one and characterized by a rapid population growth due to a decline in the death rate while fertility remains high initially; the growth rate then declines due to a decline in the birth rate. Before the transition's onset, population growth is low as high death rates tend to offset high fertility. After the transition, population growth is again below replacement level as both birth and death rates reach low levels.

denitrification_1

A heterotrophic process of anaerobic microbial respiration conducted by bacteria. Denitrification is the microbial oxidation of organic matter in which nitrate or nitrite is the terminal electron acceptor, and the end product is N2.

denitrification_2

Reduction of nitrates and nitrites to nitrogen by microorganisms.

densification

The increase in woody plants in a savanna, grassland or woodland.

deoxygenation (ocean)

Decreased oxygen concentrations in the ocean, as a result of climate change and other anthropogenic stressors, e.g. nutrient input due to inefficient fertilizer use.
