Composed of 669 biosphere reserves in 120 countries, including 16 transboundary sites, the World Network of Biosphere Reserves (WNBR) of the UNESCO Man And Biosphere (MAB) Programme consists of a dynamic and interactive network of sites of excellence. It works to foster the harmonious integration of people and nature for sustainable development through participatory dialogue, knowledge sharing, poverty reduction, human well-being improvements, respect for cultural values and by improving society’s ability to cope with climate change.For more information, visit: http://www.unesco.org/new/en/natural-sciences/environment/ecological-sciences/man-and-biosphere-programme/

The Global Lakes and Wetlands Database (GLWD) version 2 provides a comprehensive and seamless global map of inland surface waters distinguished into 33 waterbody and wetland types. GLWD v2 was developed by harmonizing the best available ground- and satellite-based data sources and has been designed to represent the maximum non-overlapping extents of aquatic ecosystems over the broad contemporary period of 1990-2020.

GLWD v2 represents a total of 18.2 million km2 of wetlands at a grid cell resolution of 15 arc-seconds (approximately 500 m at the equator). The data consist of a map of the dominant waterbody or wetland type in each grid cell, as well as 33 individual class layers which represent the sub-cell fraction of each specific class within each grid cell.

Version 2 of GLWD (Lehner et al., 2025) is the successor of the widely-used GLWD version 1 (Lehner & Döll, 2004). The quality, resolution, and format of GLWD v2 significantly improves upon GLWD v1 and supersedes the older version.

The World Heritage List includes 1248 properties forming part of the cultural and natural heritage which the World Heritage Committee considers as having outstanding universal value.

These include 972 cultural, 235 natural and 41 mixed properties in 170 States Parties. As of October 2024, 196 States Parties have ratified the World Heritage Convention.

Les ensembles de données à grande échelle sont essentiels en science hydrologique pour soutenir les études de modélisation et les évaluations globales. Le présent ensemble de données compile toutes les données sur la qualité des eaux douces disponibles sous une politique de données ouvertes (CC BY 4.0 ou équivalent) dans la base de données GEMStat dédiée à la qualité de l’eau à l’échelle mondiale (www.gemstat.org). Il comprend plus de 20 000 000 de mesures sur 608 paramètres de qualité de l'eau, couvrant 13 660 stations dans 37 pays sur la période de 1906 à 2023.

GEMStat est géré par le programme GEMS/Water du Programme des Nations Unies pour l’Environnement (PNUE) et hébergé au Centre International pour les Ressources en Eau et les Changements Globaux (ICWRGC) et à l’Institut Fédéral Allemand d’Hydrologie (BfG). Les données de GEMStat sont fournies par les Services Hydrologiques Nationaux des États membres de l’ONU.

This Layer contains the Vertical Vulnerability Map of the transboundary aquifer located within the Skadar/Shkoder - Buna/Bojana area shared by the two countries elaborated in the context of the Pilot Project "Design and testing of a multipurpose transboundary groundwater monitoring network in the Extended Drin River Basin" (DRIN) 2017 – 2020.Vertical vulnerability refers to the vulnerability of contamination threats from land-based pollution. For each polygon of the map, the numeric value of the Vertical Vulnerability class is in the field VV.
