The CDDA reporting is divided into two components: • Type 1 data includes the spatial data, aligned with the INSPIRE Protected Sites specification. • Type 2 data includes the tabular data. Both Type 1 and Type 2 data files hold mandatory CDDA information. The CDDA reporting can re-use the INSPIRE Protected Sites dataset to avoid double reporting for countries implementing the INSPIRE Directive. From 2022 the data is reported on Reportnet 3 platform. The CDDA reporting guideline and other supporting material is available from the CDDA reference page http://cdr.eionet.europa.eu/help/cdda/. December 2023 Annual The Nationally designated areas is a European inventory holding information on protected areas and the designation types which directly or indirectly create protected or other designated areas in Eionet partner countries and territories. The dataset was formerly know as CDDA but during 2024 the acronym will gradually transition to the more accurate NatDA. It is an agreed annual Eionet core data flow maintained by the EEA. The dataset is used by the EEA and e.g. the UNEP-WCMC for their main European and global assessments, products and services. The definition of a "protected area" used for inclusion of sites into the CDDA is the one adopted by IUCN: A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values. (Dudley, N. (Editor), 2008: https://portals.iucn.org/library/sites/library/files/documents/pag-021.pdf) The definition of a "designated area" within the CDDA is similar but wider. The designation types of the designated protected areas are grouped according to three categories (A, B and C) in the Designation types registry. The designation type categories A and C clearly reflects the IUCN definition above, see http://dd.eionet.europa.eu/datasets/latest/DesignationTypes In addition to "protected areas" according to the IUCN definition, designated areas adhering to the "other effective area-based conservation measures" (OECMs) definition may be included in the CDDA under designation type category B. The definition of OECMs adopted by the CBD COP in November 2018 is as follows: A geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio-economic, and other locally relevant values. https://www.cbd.int/doc/c/91c3/4484/ab24ef8c1ed10ba59b020342/cop-14-l-19-en.pdf The CDDA is the official source of designated protected area information from European countries to the World Database of Protected Areas, maintained by the UNEP-WCMC. The CDDA database was formerly known as the "Common Database on Designated Areas". The building of the database was a common effort between UNEP-WCMC, Council of Europe and EEA. Today the database available from the EEA website holds information from the Eionet partner countries only, hence the name was changed to "Nationally designated areas inventory".
