How does Iquique get water?

Water, of course, is very scarce here in this arid climate, and it comes from faraway rivers and lakes. The talk of the city is how they want to force the big mining firms to pay for desalinization plants as they do in Antofagasta, Chile’s second-largest city.

Why is the Atacama Desert an extreme environment?

This dry air has almost no water vapor so it can be easily heated by the sun, causing high ground temperatures with very low humidity. Another reason that the Atacama doesn’t get enough rainfall is because of a phenomenon called rainshadow.

Is Atacama a hot desert?

The Atacama is the driest hot desert in the world. There are some weather stations in the Atacama where there has never been any rain! Not all deserts are hot. First, this desert is located in the “rain shadow” between two mountain ranges, the Andes and the Chilean Coast Range.

Why is Atacama so dry?

Cold air can’t hold as much water vapor as warm air so it dries out any water left in the air. This mix of mountains, winds, and ocean currents combines to make the Atacama incredibly dry. The Atacama is also one of the oldest deserts in the world. That is much older than other very dry deserts.

What is the foggy phenomenon that rolls over the Atacama bringing much needed moisture known as?

In this part of the Atacama, fog is the only water source keeping the microbes alive. It rolls over the coastal range at night and temporarily moistens the salt, which awakens as a shape-shifting blob in a phenomenon called deliquescence.

What aquifer is located in Iquique Chile?

Aquifers within the Pampa del Tamarugal Basin (Atacama Desert, northern Chile) are the sole source of water for the coastal city of Iquique and the economically important mining industry. Despite this, the regional groundwater system remains poorly understood.

How much water does the Atacama Desert get?

But with several 48-meter (158 feet) nets installed, the location efficiently collects 1,000 liters (264 gallons) of water in 10 containers per day from fog. ‘There is typically from 0.05 to 0.5 grams of liquid water in a cubic meter of fog,’ according to Canadian non-profit FogQuest, who helped set up the giant nets in Chile.

Which is the driest desert in the world?

Agricultural expert Daniel Rojas might have been talking about any place on Earth where water is hard to come by, but his words have a particular salience in Peña Blanca, Chile. The remote, drought-stricken community lies on the fringes of an expanding Atacama Desert, the driest (non-polar) desert on Earth.

This is no more evident than in the tiny fishing communities that dot Chile’s coastline, where the desert meets the sea. The impoverished anglers that live in these little coves survive on around eight liters (two gal) of water each day, meaning showering isn’t an option.
