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.

This map provides detailed information about dams (e.g. uses, capacity, ...) in Central Asia.For more information, visit FAO AQUASTAT Dams Geo-referenced database: www.fao.org/nr/water/aquastat/dams/index.stm

Groundwater stress measures the ratio of groundwater withdrawal relative to its recharge rate over a given aquifer. Values above one indicate where unsustainable groundwater consumption could affect groundwater availability and groundwater-dependent ecosystems.

Transboundary aquifer vulnerability to climate change is calculated as the extent of expected groundwater budget regime change in response to change in climate. A high vulnerability is indicative of transboundary aquifers actively interacting with streams, atmosphere and/or sea (e.g. coastal aquifers, SIDS, shallow watertable aquifers, karst aquifers).

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 Guatemala. 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/

This layer presents the ratio of female learners to school toilets in 53 schools in Lima province, Peru. On average, 30 female learners share one toilet, and 36 male learners share the same toilet. From the responses, two schools have no toilet facilities for girls.

Flood occurrences is the number of flood recorded from 1985 to 2011. Flood counts were calculated by intersecting hydrological units with estimated flood extent polygons.

Data is expressed as the percentage of households connected to the sewage network.

The dataset presents 687 rivers associated to 405 Major River Basins.Data was collected within the framework of the BGR-UNESCO "World-wide Hydrogeological Mapping and Assessment Programme" (WHYMAP): www.whymap.org

This map provides detailed information about dams (e.g. uses, capacity, ...) in South America.For more information, visit FAO AQUASTAT Dams Geo-referenced database: www.fao.org/nr/water/aquastat/dams/index.stm

Groundwaters of the Dinaric Karst form some of the world's largest karst aquifer systems. The Dinaric region contains huge amounts of high quality groundwater. It is one of the major contributors of freshwater entering the Adriatic Sea. The Dinaric Karst Aquifer System extends from NE Italy through Slovenia, Croatia, Bosnia & Herzegovina, Montenegro to Albania. Karst formations connected with the Dinaric carbonate chain outcrop also in Serbia, FYR Macedonia, and possibly in NW Greece.In the framework of the DIKTAS GEF-project (2010-2014) executed by UNESCO-IHP, the four DIKTAS project countries (Albania, Bosnia and Herzegovina, Croatia and Montenegro) have agreed to create two mechanisms in order to facilitate enhanced consultation and exchange of information between the governmental entities that are involved in water resources management.For more information, visit: http://diktas.iwlearn.org/

This map provides data and information about the major groundwater resources of the world. About 35% of the area of the continents (excluding the Antarctic) is underlain by relatively homogeneous aquifers, 18% is endowed with groundwater, some of which are extensive, in geologically complex regions. Nearly half of the continental areas contain generally minor occurrences of groundwater that are restricted to the near-surface unconsolidated rocks, where groundwater resources are usually sufficient for small to medium-sized population centres.For more information, visit: www.whymap.org

The Ocotepeque-Citala Aquifer is a small alluvial transboundary aquifer shared by Honduras and El Salvador. It is located in a mountainous valley and is characterised by strong links between groundwater and surface water, in this specific case the transboundary Río Lempa.

This layer presents wastewater discharge points and the sensitivity of receiving areas. Those data were collected from the reporting of European Union Member States, as part of the Urban Waste Water Treatment Directive (UWWTD) implementation, which concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of waste water from certain industrial sectors. Its objective is to protect the environment from the adverse effects of the above mentioned waste water discharges. For more information, visit the UWWTD waterbase website: www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-4#tab-european-data, and access the Directive: http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:31991L0271

The 1992 UNECE Convention aims to protect and ensure the quantity, quality and sustainable use of transboundary water resources by facilitating cooperation, and provides an intergovernmental platform for the day-to-day development and advancement of transboundary cooperation. Negotiated as a regional instrument, it turned into a universally available legal framework for transboundary water cooperation, following the entry into force of amendments in February 2013, opening it to all UN Member States. As of 1st March 2016, countries outside the ECE region can accede to the Convention.The 1997 United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses is the only treaty governing shared freshwater resources that is of universal applicability. It is a framework convention, in the sense that it provides a framework of principles and rules that may be applied and adjusted to suit the characteristics of particular international watercourses.

This water consumption is expressed in liters/capita/day. The consumption of potable water is widely variable, with a large gap between cities. Household consumption per capita varies from 28 to 631 liters per day, a factor of 20.The full data are available online. For more information, visit: www.waterstatistics.org
