This layer provides a compilation of estimated storm surges triggered by tropical cyclones of Saffir-Simpson category (Don't forget to zoom on the coasts!). The Saffir–Simpson Hurricane Wind Scale classifies hurricanes into five categories distinguished by the intensities of their sustained winds. To be classified as a hurricane, a tropical cyclone must have maximum sustained winds of at least 74 mph (Category 1), to winds exceeding 156 mph (Category 5).For more information, visit the Global Risk Data Platform: http://preview.grid.unep.ch/index.php?preview=data&events=surg

This layer shows the volume of wastewater generated by industry in the Europe and North America region, expressed in millions of cubic meters. Spain generates the largest volumes of industrial wastewater with 6535.2 millions m3, while Cyprus is the smallest producer of industrial wastewater with 1.9 millions m3.For more information, acces the 2017 UN World Water Development Report: http://www.unesco.org/new/en/natural-sciences/environment/water/wwap/wwdr/2017-wastewater-the-untapped-resource/

Population using an improved drinking water source (piped water into dwellings, yards or plots; public taps or standpipes; boreholes or tubewells; protected dug wells; or protected springs and rainwater) that is located on premises and available when needed and which is free of faecal and priority chemical contamination.

This layer identifies if any water was available at the water point on the day of the visit (recognizing that it may be a limited flow) in Bolivia. Data was gathered from the Water Point Data Exchange (WPDx) platform, a tool established for sharing water point data throughout the global water sector. The goal of the Water Point Data Exchange is to simplify the way water point data is shared so all stakeholders can work more efficiently.

Area actually irrigted, as a percentage of area equipped for irrigation. The statistics with a reference year closest to year 2005 were selected for this version 5 of the Global Map of Irrigation Areas.For mor information, visit: http://www.fao.org/nr/water/aquastat/irrigationmap/index10.stm

Inter-annual variability measures the variation in water supply between years.

This map presents information on coastal aquifers in the Mediterranean.

This map presents areas identified as having saline groundwater (i.e. salinity regionally exceeding 5 g/l), and where groundwater is generally not suitable for human consumption.For more information, visit: www.whymap.org

Data is given as the percentage of water abstracted for drinking supply that comes from groundwater. Abstraction sources include: groundwater, spring water, surface water, other sources and imported water.

This map presents the percentage of population with access to improved sanitation for the last collected values in world cities during the period 1990 to 2007. It also provides information for older data up to 1990. For more information, visit: http://urbandata.unhabitat.org

This layer shows UNESCO World Heritage site subjected to flood risk.

This map presents areas of heavy groundwater abstraction with over-exploitation around the world.For more information, visit: www.whymap.org

Upstream storage measures the water storage capacity available upstream of a location relative to the total water supply at that location from 1950 to 2010. Higher values indicate areas more capable of buffering variations in water supply (i.e. droughts and floods) because they have more water storage capacity upstream.

The Human Water Stress indicator deals with the quantity of water available per person per year relative to the internal and upstream area water supplies, on the premise that the less water available per person, the greater the impact on human development and well-being, and the less water there is available for other sectors.For more information, visit: http://twap-rivers.org/

Calculated as the long-term mean transboundary groundwater recharge, including man-made components, divided by the number of inhabitants of the area occupied by the aquifer. Indicator is expressed in m3/yr/capita

Measures the percentage of freshwater amphibian species classified by IUCN as threatened. Higher values indicate more fragile freshwater ecosystems and may be more likely to be subject to water withdrawal and discharge regulations. For each catchment, the total number of threatened freshwater amphibian species was counted and divided by the total number of freshwater amphibian species whose ranges overlap the catchment. Catchments with fewer than two amphibian species were excluded.

Seasonal variability measures variation in water supply between months of the year.

Data is given in m³/capita/year.The full data are available online. For more information, visit: www.waterstatistics.org

This layer shows limits pose by challenges and capacities to African cities. Although the main challenges in terms of magnitude exist in the larger cities, these are also relatively better-placed in terms of institutional and economic capacity to address the problems through economies of scale. Most smaller cities lack this advantage and clearly need to focus on capacity-building as a necessary step towards improving their water and wastewater management systems.

Water accounts for the main source of production of electrical power in the Dinaric Alps, and contribute significantly to the countries’ economies. Albania gains 83 % of all electricity from hydropower plants, Montenegro 75 %, Bosnia and Herzegovina 60% and Croatia 54 %.Data were collected in the framework of the DIKTAS project.
