Global Inundation Map (GLIN)
The Global Inundation Map, termed GLIN, is a global raster map showing estimates for average annual minimum, average annual maximum, and long-term maximum inundation extents at 15 arc-second spatial resolution. In a partner product (GLIN-monthly) monthly average inundation extents are represented
Vulnerability of European Ephemeroptera, Plecoptera and Trichoptera to Climate Change
A dataset of bio-ecological traits of 1,942 Ephemeroptera,
Plecoptera, and Trichoptera (EPT) taxa was used to analyze the potential
vulnerability of EPT species to climate change at the scale of European
ecoregions.
Global Waterfall Database (HydroFALLS)
The Global Waterfall Database, termed HydroFALLS, is a point
shapefile and related attribute table showing the location of 4362
waterfalls including their names and estimated mean river flow. The
database has been compiled and validated using a variety of source
information and constitutes the first consistent global GIS layer of
waterfall features. The point locations have been co-registered to the
global HydroSHEDS river network.
Global Freshwater Fish Species Richness
The 1,054 drainage basins in this map cover more than 80% of the
world’s continental surface area. The evaluation of native, non-native,
and endemic freshwater fish species is based on an extensive literature
survey.
Global Diversity Patterns in Freshwater Systems
Global patterns of freshwater species diversity are described
using two diversity descriptors (species richness and degree of
endemicity) for freshwater amphibians, birds, crayfish, fishes, mammals
and reptiles per HydroBASIN basin.

European Freshwater Alien Species
Introductions of invasive alien species (IAS) are considered one
of the main pressures to freshwater ecosystems. In this context, the
maps presented here aim to assist scientists and policy makers in their
efforts to prevent and control alien invasions.
Freshwater Fish Extinction Rates due to Water Availability Loss from Climate Change
Based on a global geospatial framework of river drainage basins
and on future climate data from 18 Global Circulation Models (GCMs) from
the ‘pessimistic’ IPCC scenario (A2), we quantify future active
drainage basin area losses and combine them with an extinction rate–area
curve to project future surface-dependent extinction rates. We then
estimate the future projected change in extinction rate worldwide and
project the number of extinct species in 1010 river basins.
Vulnerability of European Ephemeroptera, Plecoptera and Trichoptera to Climate Change
A dataset of bio-ecological traits of 1,942 Ephemeroptera,
Plecoptera, and Trichoptera (EPT) taxa was used to analyze the potential

ecoregions.
Freshwater Species Data: Increasing Knowledge on Biodiversity in Sub-Saharan Africa
Patterns of richness and threat for four freshwater groups
represent significant new knowledge on the distribution and status of
Africa’s biodiversity.
Freshwater Biodiversity and Protected Areas in Africa: a Gap Analysis
This map shows that the existing protected areas in mainland
Africa do not adequately cover sub-catchments identified as potential
freshwater Key Biodiversity Areas. Only 21.30% of the total area of
these priority sub-catchments fall within the protected area network.
Multiple Human Pressures and Their Spatial Patterns in European Running Waters
This study represents the first high-resolution data analysis of
human pressures at the European scale, where important pressure criteria
for 9,330 sampling sites in 14 European countries were analysed.
