Water Scarce

Today, cities are looking farther beyond their limits for clean water. Some cities involve desalinization procedures, investing billions of dollars to partially supply clean water. This kind of process in energy intensive, therefore, countries with a combination between water scarce and oil rich are the most probable to use this technique. This footprint analysis involve 534 cities, who draw water from 20 percent of the world’s land surface.

The Cost

The use of the land covering the watersheds have an enormous impact in the cost and treatment of the water, as well as for the availability and quality of the water supply. Globally, a watershed is covered by 40 percent of forestall area, 30 percent of cropland and 20 percent of grassland and pasture; but it will vary from country to country.

Today, cities are looking farther beyond their limits for clean water. Many cities rely partially or totally on surface water sources. The study of the Natural Conservancy focus on the analysis of surface water quality and quantity.

Today, cities are looking farther beyond their limits for clean water. Many cities rely partially or totally on non-surface water like groundwater. The study of the Natural Conservancy focus on the analysis of surface water quality, while accounting for the groundwater importance in urban supply but without evaluation of the sustainability of the source.

The World

This map shows the source watersheds of 534 cities. "Although the 100 largest cities in the world occupy less than 1 percent of our planet’s land area, their source watersheds — the rivers, forests and other ecosystems from which they get their water— cover over 12 percent. [...] The availability and quality of that water supply, and hence the costs to move and treat it, depend heavily on how land in those source watersheds is used." (Nature Conservancy, 2015).

High Nutrient

In cases were the watersheds are exploited for intensive agricultural purposes, as consequence the fertilizer concentration increase. Thus, the fertilizer filters into the water and rise the accumulation of common nutrients, phosphorus and nitrogen, affecting their proper cycle. Around 384 million urbanities receive their drinking water from watersheds with high nutrient pollution. This map shows the total quantity of phosphorous moving out of a watershed in a given time interval, being expressed as units of tonnes/km2/year, organized into four categories: “Low” if less than 8kg/km2; “Medium” if between 8-20 kg/km2; “High” if more 20 kg/km2 and “No Information”.

Water Withdrawals

Water withdrawals or water abstractions, is the freshwater taken from ground or surface water sources and conveyed to a place of use. These, normally, are sectorial distributed and in this specific case, five of the most important water sectors such as irrigation, livestock-based agriculture, industry, thermal electricity production, and households and small businesses are examined. (Estimated from the WaterGAP3 model) This map shows the quantity of WTA taken from available watersheds.

The average distance to surface diversion sources is expressed in kilometers. Today, cities are looking farther beyond their limits for clean water. On average, cities retrieve surface water from an average distance of 57.86 km. Note that if a city gets a small fraction of its water from surface water, there will be calculated values for this metric, but it is not particularly meaningful for a city's water risk or opportunity profile.

This layer shows the percentage of water sourced from watershed(s) outside the watershed within which a given city resides. On average, cities secure 43% of their water supply via intebasin transfers. Note that if a city gets a small fraction of its water from surface water, there will be calculated values for this metric, but it is not particularly meaningful for a city's water risk or opportunity profile.
