This list of passport Descriptors for Crop Wild Relatives conserved in situ constitutes the minimum initial list for CWR in situ data exchange. For each descriptor, this tool provides a brief explanation of content, its coding scheme, and a suggested field name. It has been developed taking the Core Descriptors for in situ conservation of CWR v.1 published by Bioversity International in 2013 as the starting point. It also builds on recent experiences conducted by the Secretariat of FAO’s International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) in the context of the development of its Global Information System (GLIS). One of the main factors adversely affecting the conservation, use, monitoring and reporting of Plant Genetic Resources for Food and Agriculture (PGRFA) is the lack of access to data and inefficient exchange of information. This lack of standardization had prevented the PGRFA community from exchanging PGRFA data worldwide and had, for years, been one of the main challenges for the effective conservation and sustainable use of plant material. The Secretariat of the FAO International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) undertook to address the gaps and the lack of coherence in the documentation methods for plant resources, in particular for Crop Wild Relatives (CWR) conserved under in situ conditions, through the development of an international standard contained in this booklet
