Reed Noss, "Indicators for Monitoring Biodiversity: A Hierarchial Approach", Conservation Biology 4(4):355-364. 1990. Definitions of Agricultural Biodiversity - 1 CBD Decision V/5, appendix ‘a broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of agriculture that constitute the agro-ecosystem: the variety and variability of animals, plants and micro-organisms, at the genetic, species and ecosystem levels which are necessary to sustain the key functions of the agro-ecosystem, its structure and processes.’
Reed Noss, "Indicators for Monitoring Biodiversity: A Hierarchial Approach", Conservation Biology 4(4):355-364. 1990. Definitions of Agricultural Biodiversity – 2 ‘a continuum from cultivated biodiversity to wild biodiversity’ Millennium Ecosystem Assessment (MA 2005) Cultivated or ‘planned’ biodiversity – crops, livestock, aquaculture fisheries. Associated biodiversity – supports agricultural production through nutrient cycling, soil formation, pest control, pollination, etc. Additional or other biodiversity – also occurs within the agricultural ecosystem. Wild biodiversity outside agricultural ecosystems
