The Standard Material Transfer Agreement (SMTA) is a standard contract that sets out the terms and conditions ensuring that the relevant provisions of the International Treaty are followed when transferring plant genetic material that is included in the Multilateral System. (FAO, 2024. The Multilateral System. The Standard Material Transfer Agreement https://www.fao.org/plant-treaty/areas-of-work/the-multilateral-system/smta/en/)
Note
Standard Material Transfer Agreements offer pre-negotiated terms and conditions for common transfers, while Material Transfer Agreements are individually negotiated agreements that are customized to the specific circumstances of each transfer. For "Material Transfer Agreements", see <c_331333>. While the definition of SMTAs refers to plant genetic material, SMTAs are also used in the context of the transfer of other biological materials and chemicals.
Sylvatic cycle Is a natural disease maintenance or transmission cycle that involves non-human wild animals and insects. (International Alliance against Health Risks in Wildlife Trade. 2023. Glossary. https://alliance-health-wildlife.org/wp-content/uploads/2023/03/Glossary_Int.Alliance-against-Health-Risks-in-Wildlife-Trade.pdf)
Note
Sylvatic refers to the occurrence of a subject in or affecting wild animals. The sylvatic cycle is the fraction of the pathogen population's lifespan spent cycling between wild animals and vectors.
A petal is a unit of the corolla, when completely free. Petals are modified leaves that surround the reproductive parts of flowers.

Programs, actions initiatives aimed at improving the quality of life for people living in poverty. Poverty alleviation encompasses two discrete meanings, namely poverty mitigation and poverty reduction. Poverty mitigation implies that people are prevented from becoming poorer whereas poverty reduction describes a situation where people are being lifted out of poverty (Angelsen and Wunder 2003). (Angelsen, A. and S. Wunder, 2003. Exploring the forest – poverty link: key concepts, issues and research implications. CIFOR Occasional Paper No. 40. Center for International Forestry Research, Bogo, Indonesia.)
A fluid, heterogeneous formulation consisting of a stable dispersion of active ingredients in the form of solid particles and fine globules in a continuous water phase. (http://www.fao.org/fileadmin/templates/agphome/documents/Pests_Pesticides/Specs/JMPS_Manual_2016/3rd_Amendment_JMPS_Manual.pdf)
Reactive environment protection. It includes (a) reduction or neutralization of residuals, (b) changes in the spatial distribution of residuals, (c) support of environmental assimilation and (d) restoration of ecosystems, landscape and so forth. (United Nations (1997): Glossary of Environment Statistics. Studies in Methods, Series F, No. 67)
Diffraction [of light] s the slight bending of light as it passes around the edge of an object. The amount of bending depends on the relative size of the wavelength of light to the size of the opening. (http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/opt/mch/diff.rxml)
Seeds of coriander, (Coriandrum sativum L.). The dry fruits are referred to as coriander seeds in commerce. Coriander is commonly found both as whole dried seeds and in ground form.
