Data is given as the percentage of water abstracted for drinking supply that comes from desalination of marine water and/or from recycled water. Other abstraction sources include: groundwater, spring water, surface water, and imported water.

The information presented highlights large flood events from 1985 to 2016 identified by the Dartmouth Flood Observatory. For more information, visit: floodobservatory.colorado.edu/Archives/index.htmlFor mapping purposes, some types of flood events have been merged into one, under the "MAINCAUSEF" attribute. Please refer to the "MAINCAUSE" attribute for original data.

The Groundwater Natural Background Quality indicators stands for the percentage of the transboundary aquifer (TBA) area where groundwater natural quality satisfies local drinking water standards.In north-eastern Africa, parts of the Middle East and Northern India and Pakistan, low recharge values in TBAs are combined with high population densities. In these areas, return flows from irrigation and other human induced recharge appear to play a major role in the sustainability of groundwater resource utilization. Very low natural quality (< 20 per cent of the aquifer area) coincides with TBAs highly impacted by irrigation return flows in densely populated areas with low to medium natural recharge, like the Nubian, Indus, Pre Caspian TBAs.For more information, visit: https://ggis.un-igrac.org/ggis-viewer/viewer/twap/public/default

This layer presents the ratio of female learners to school toilets in 100 schools in 3 provinces of El Salvador. On average, 56 male learners share one toilet, whereas 51 female learners share the same toilet. From our responses, 9 schools indicated they had no toilet facilities, and data is missing for 3 schools.

Total charges is expressed in US dollars. The amount of total charges is derived from the addition of total charges for drinking water, environmental charges, and VAT and/or other taxes.The full data are available online. For more information, visit: www.waterstatistics.org

Landfills are rarely properly constructed or lined and therefore represent a potential source of contamination.Solid waste in the form of hundreds of unregulated landfills and illegal dumping sites in Croatia, Bosnia-Herzegovina, Montenegro and Albania constitutes one of the main threats to the overall groundwater quality of the Dinaraic Karst Transboundary Aquifer System (DIKTAS). For the vulnerable karst environment of the Dinaric region, which has a very limited auto-purification capacity, this is the most serious current as well as (potential) future problem.Data were collected in the framework of the DIKTAS project.

Drought severity measures the average length of droughts times the dryness of the droughts from 1901 to 2008. Drought is defined as a contiguous period when soil moisture remains below the 20th percentile. Length is measured in months, and dryness is the average number of percentage points by which soil moisture drops below the 20th percentile.

This layer shows the volume of collected wastewater in the Arab States, expressed in millions of cubic meters. Access to improved sanitation is largely prevalent in the Arab region, but connections to sewerage networks and wastewater treatment facilities remain more limited. Network coverage is generally provided in larger urban centers, while septic tanks and cesspits remain common in rural areas and in the region's least developed countries. Off-network sanitation systems, however, complicate te collection and treatment of wastewater and reduce the ability to sustainably manage wastewater as a resource in most areas.

The total surface area of the Adriatic basin in the four countries is 65,545 km² while the Black Sea basin covers 44,865 km² of the project area. Dash lines represent the limit between sub-basins. Data was collected in the framework of the DIKTAS project.

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. For more information, visit the WPDx website at https://www.waterpointdata.org/

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

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
