Geographic areas with homogeneous sets of climatic parameters and natural resource characteristics, such as rainfall, solar radiation, soil types and soil qualities, which correspond to a level of agricultural potential.

Africa assessment, Americas assessment, Pollination assessment, Global assessment (1st work programme)
agroecosystem

A human activity system that provides specific services and possesses certain characteristics such as defined biodiversity, a determined ecological succession and food webs and nutrient cycles.

Asia-Pacific assessment
agrobiodiversity

A broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of biological diversity that constitute the agricultural ecosystems, also named agro-ecosystems: the variety and variability of animals, plants and micro-organisms, at the genetic, species and ecosystem levels, which are necessary to sustain key functions of the agro-ecosystem, its structure and processes (CBD COP decision V/5, appendix). Agricultural biodiversity is the outcome of the interactions among genetic resources, the environment and the management systems and practices used by farmers, in some cases over millennia.

Land degradation and restoration assessment
agrobiodiversity

Agrobiodiversity or agricultural biodiversity is the biological diversity that sustains key functions, structures and processes of agricultural ecosystems. It includes the variety and variability of animals, plants and micro-organisms, at the genetic, species and ecosystem levels.

The result of natural selection processes and the careful selection and inventive developments of farmers, herders and fishers over millennia. A vital sub-set of biodiversity.

Asia-Pacific assessment
agrochemical

Any substance used to help manage an agricultural ecosystem, or the community of organisms in a farming area. Agrochemicals include: (i) fertilizers; (ii) liming and acidifying agents; (iii) soil conditioners; (iv) pesticides; and (v) chemicals used in animal husbandry, such as antibiotics and hormones.

Land degradation and restoration assessment
agroecological agriculture

An approach that aims to regenerate functionally interacting biodiversity leading to sustainable, resilient systems. Methods are knowledge, management and labour- intensive rather than input intensive, and are often rooted in traditional farming practices and/or are co-developed by farmers and scientists working together.

Pollination assessment
agroecology

The science and practice of applying ecological concepts, principles and knowledge (i.e. the interactions of, and explanations for, the diversity, abundance and activities of organisms) to the study, design and management of sustainable agroecosystems. It includes the roles of human beings as a central organism in agroecology by way of social and economic processes in farming systems. Agroecology examines the roles and interactions among all relevant biophysical, technical and socioeconomic components of farming systems and their surrounding landscapes.

Land degradation and restoration assessment, Global assessment (1st work programme), Europe and Central Asia assessment
agroecosystem

An ecosystem, dominated by agriculture, containing assets and functions such as biodiversity, ecological succession and food webs. An agroecosystem is not restricted to the immediate site of agricultural activity (e.g. the farm), but rather includes the region that is impacted by this activity, usually by changes to the complexity of species assemblages and energy flows, as well as to the net nutrient balance.

Land degradation and restoration assessment
anthropocene

A proposed term for the present time interval, which recognizes humanity’s profound imprint on and role in the functioning of the Earth system. Since it was first proposed in 2000, the term has evolved in breadth and diversely, now ranging from a proposed definition of a new geological epoch, a widely-used metaphor for global change, a novel analytical framework, a meme about the relationship of society to nature, and the framing for new and contested cultural narratives. Different starting periods have been proposed for the geological definition of the Anthropocene, including early agriculture and domestication, colonial species exchange, the onset of the industrial revolution, nuclear bomb deployment in 1945, and the post-WWII period characterized by the great acceleration of global changes and the spread of techno-fossils. A proposal to formalize the ‘Anthropocene’ as a defined geological unit within the Geological Time Scale remains under discussion by the ‘Anthropocene’ Working Group for consideration by the International Commission on Stratigraphy.
