Water is the world’s most vital resource. Beyond its basic functions of sustaining life, it’s also a precious commodity – one that billions of people in the world have trouble accessing.
Today’s infographic is from Raconteur, and it puts the global issue of water access into staggering perspective. It’s a two-fold problem: safe drinking water is hard to come by, while basic access to sanitation is less common than you’d expect.
Diving into Drinking Water
It’s easy to take water for granted when it comes out of every tap in developed economies, but the stark reality is that 2.1 billion people worldwide can’t get safe water this way.
Many people in the world spend hours waiting in long lines, often multiple times a day, for community-shared water, or, they have to travel to distant sources just to collect it.
World regions are categorized according to five classifications for drinking water access.
Here’s a breakdown of how each region fares.
|Region||Safely Managed||Basic||Limited||Unimproved||Surface Water|
|Eastern Europe and Central Asia||84%||11%||2%||2%||1%|
|Middle East and North Africa||77%||16%||4%||2%||1%|
|Latin America and Caribbean||65%||31%||1%||2%||1%|
|Eastern and Southern Africa||26%||28%||18%||16%||12%|
|West and Central Africa||23%||40%||10%||20%||7%|
|East Asia and Pacific||-||94%||1%||4%||1%|
The water crisis in Flint, Michigan is a dire exception to the safely managed water rule in North America. After a change in river source in 2014, insufficient water treatment resulted in lead from pipes leaching into the drinking water, affecting over 100,000 residents.
The Struggle of Sanitation
The invention of the toilet in 1875 is credited with saving one billion lives to date. Yet, poor water hygiene and its associated diseases claim the lives of roughly one million people annually.
This is because roughly 4.5 billion people still don’t have access to a toilet, with the problem being particularly acute on the African continent. More than half of the population in Eritrea (76%), Niger (71%), Chad (68%) and South Sudan (61%), for example, do not have any access to even basic sanitation.
Every Drop of Water Counts
According to the World Economic Forum, water has been a top-five global risk for the past seven years.
From an economic perspective, it’s easy to see why:
- An estimated $260 billion is lost globally each year from the lack of basic water and sanitation.
- Almost $18.5 billion in benefits can come from universal access to basic water and sanitation.
Securing water access has profound consequences. For every $1 invested in water and sanitation, there’s a $4 return from lower health costs, higher productivity, and fewer preventable deaths.
Fortunately, progress is being made on the global scale. Between 2001 and 2015, there’s been a 9% improvement in safe drinking water, while safely managed sanitation has risen by 10%.
Visualizing the Biggest Risks to the Global Economy in 2020
The Global Risk Report 2020 paints an unprecedented risk landscape for 2020—one dominated by climate change and other environmental concerns.
Top Risks in 2020: Dominated by Environmental Factors
Environmental concerns are a frequent talking point drawn upon by politicians and scientists alike, and for good reason. Irrespective of economic or social status, climate change has the potential to affect us all.
While public urgency surrounding climate action has been growing, it can be difficult to comprehend the potential extent of economic disruption that environmental risks pose.
Front and Center
Today’s chart uses data from the World Economic Forum’s annual Global Risks Report, which surveyed 800 leaders from business, government, and non-profits to showcase the most prominent economic risks the world faces.
According to the data in the report, here are the top five risks to the global economy, in terms of their likelihood and potential impact:
|Top Global Risks (by "Likelihood")||Top Global Risks (by "Impact")|
|#1||Extreme weather||#1||Climate action failure|
|#2||Climate action failure||#2||Weapons of mass destruction|
|#3||Natural disasters||#3||Biodiversity loss|
|#4||Biodiversity loss||#4||Extreme weather|
|#5||Humanmade environmental disasters||#5||Water crises|
With more emphasis being placed on environmental risks, how much do we need to worry?
According to the World Economic Forum, more than we can imagine. The report asserts that, among many other things, natural disasters are becoming more intense and more frequent.
While it can be difficult to extrapolate precisely how environmental risks could cascade into trouble for the global economy and financial system, here are some interesting examples of how they are already affecting institutional investors and the insurance industry.
The Stranded Assets Dilemma
If the world is to stick to its 2°C global warming threshold, as outlined in the Paris Agreement, a significant amount of oil, gas, and coal reserves would need to be left untouched. These assets would become “stranded”, forfeiting roughly $1-4 trillion from the world economy.
Growing awareness of this risk has led to a change in sentiment. Many institutional investors have become wary of their portfolio exposures, and in some cases, have begun divesting from the sector entirely.
The financial case for fossil fuel divestment is strong. Fossil fuel companies once led the economy and world stock markets. They now lag.
– Institute for Energy Economics and Financial Analysis
The last couple of years have been a game-changer for the industry’s future prospects. For example, 2018 was a milestone year in fossil fuel divestment:
- Nearly 1,000 institutional investors representing $6.24 trillion in assets have pledged to divest from fossil fuels, up from just $52 billion four years ago;
- Ireland became the first country to commit to fossil fuel divestment. At the time of announcement, its sovereign development fund had $10.4 billion in assets;
- New York City became the largest (but not the first) city to commit to fossil fuel divestment. Its pension funds, totaling $189 billion at the time of announcement, aim to divest over a 5-year period.
A Tough Road Ahead
In a recent survey, actuaries ranked climate change as their top risk for 2019, ahead of damages from cyberattacks, financial instability, and terrorism—drawing strong parallels with the results of this year’s Global Risk Report.
These growing concerns are well-founded. 2017 was the costliest year on record for natural disasters, with $344 billion in global economic losses. This daunting figure translated to a record year for insured losses, totalling $140 billion.
Although insured losses over 2019 have fallen back in line with the average over the past 10 years, Munich RE believes that long-term environmental effects are already being felt:
- Recent studies have shown that over the long term, the environmental conditions for bushfires in Australia have become more favorable;
- Despite a decrease in U.S. wildfire losses compared to previous years, there is a rising long-term trend for forest area burned in the U.S.;
- An increase in hailstorms, as a result of climate change, has been shown to contribute to growing losses across the globe.
The Ball Is In Our Court
It’s clear that the environmental issues we face are beginning to have a larger real impact. Despite growing awareness and preliminary actions such as fossil fuel divestment, the Global Risk Report stresses that there is much more work to be done to mitigate risks.
How companies and governments choose to respond over the next decade will be a focal point of many discussions to come.
Timelapse Maps: An Overview of Our Changing Planet
From rapid urbanization to retreating glaciers, these timelapsed satellite maps capture the drastic changes the Earth’s surface has undergone.
Humankind’s impact on the world is obvious, but our spatial patterns are sometimes difficult to recognize from the ground.
Publicly accessible, high-quality satellite imagery has been a game changer in terms of understanding the scope of forces such as urbanization and land use patterns.
Google Timelapse Maps
Google Earth’s timelapsed satellite maps capture the drastic changes the planet’s surface has undergone over the past 34 years. Each timelapse comprises 35 cloud-free pictures, which have been made interactive by the CREATE Lab at Carnegie Mellon University.
Three different satellites acquired 15 million images over the past three decades. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program. For the years 2015 to 2018, Google combined imagery from Landsat 8 and Sentinel-2A. Sentinel is part of the European Commission and European Space Agency’s Copernicus Earth observation program.
Deforestation, urban growth, and natural resource extraction are just some of the human patterns and impacts that can be visualized.

Cities and Infrastructure
Urban Growth: Pearl River Delta, China
Up to 1979, China’s Pearl River Delta had seen little urbanization. However in 1980, the People’s Republic of China established a special economic zone, Shenzhen, to attract foreign investment. In the following years, buildings and paved surfaces rapidly replaced the rural settings around the river delta. This is the Lunjiao area just south of Guangzhou.
Urban Growth: Cairo, Egypt
The present-day location of Cairo has been a city for more than 1,000 years, and its constrained urban footprint is now bursting at the seams thanks to Egypt’s population growth. A new city is being built in the nearby stretch of desert land (agricultural land is scarce) that will one day replace ancient Cairo as Egypt’s capital. If the government’s ambitious plans are realized, this desert boomtown could have a population of over 6 million people.
The Egyptian state needed this kind of project a long time ago. Cairo [is] a capital that is full of traffic jams, very crowded. The infrastructure cannot absorb more people.

Urban Growth: Phoenix, Arizona
According to estimates from the U.S. Census Bureau, Phoenix is the fastest-growing city in the United States. Over the past two decades, the suburb of Chandler evolved from agricultural uses to sprawling residential developments. This pattern was repeated in a number of cities in the Southern U.S., most notably Las Vegas.
Construction: The Brandenburg Airport, Germany
Berlin’s long overdue Brandenburg Airport began construction in 2006, with the airport initially expected to open in 2011. However, the airport has been subject to numerous delays and the airport now has a new opening date. Berlin Brandenburg Airport is now expected to open on Oct. 31, 2020.
Megaproject: Yangshan Port
The Port of Shanghai became one of the most important transportation hubs in the world after the completion of its offshore expansion – the Yangshan Port.
Building this massive port was a gargantuan engineering feat. First, land reclamation was used to connect two islands 20 miles southeast of Shanghai. Next, the port was connected to the mainland via the Donghai Bridge, which opened in 2005 as the world’s longest sea crossing. The six-lane bridge took 6,000 workers two and half years to construct.
In 2016, the Port of Shanghai was the largest shipping port in the world, handling 37.1 million twenty-foot container equivalents.
Mining: Chuquicamata, Chile
Chuquicamata is the largest open pit copper mine by volume in the world, located 800 miles north of the Chilean capital, Santiago. In 2019, Chile’s national mining company Codelco initiated underground mining at Chuquicamata.
Deforestation: Ñuflo de Chávez, Bolivia
Ñuflo de Chávez is one of the 15 provinces of the Bolivian Santa Cruz Department. Satellite images of southern Ñuflo de Chávez illustrate deforestation from agrarian expansion in the jungles of the Amazon. From the air, the deforestation takes on a unique grid pattern with circular clearings. Developed as part of an organized resettlement scheme, each circle is anchored by community amenities and housing, and surrounded by fields of soybeans cultivated for export.
According to Brazil’s National Institute for Space Research, 8.4 million soccer fields of land have been deforested in the Amazon over the past decade.
Shale Gas Boom: Odessa, Texas
The small town of Odessa sits in the middle of one of the most productive shale gas regions in the world, the Permian Basin. The region is expected to generate an average of 3.9 million barrels per day, roughly a third of total U.S. oil production. While the gas may come from underground, the pursuit of this source of energy has drastically altered the landscape, marking the terrain with roads, wells, and housing for workers.
Drying of the Aral Sea: Kazakhstan and Uzbekistan
It took almost 30 years to make a sea disappear. When the Soviet Union diverted the Amu Darya and Syr Darya rivers to irrigate cotton and rice fields in the 1960s, it turned the Aral Sea into a desert. Once the world’s fourth largest lake, the region is struggling to restore water levels and aquatic habitats.
Glacier Retreat: Columbia Glacier, Alaska, USA
The Columbia Glacier is a tidewater glacier that flows through the valleys of the Chugach Mountains and into Alaska’s Prince William Sound. Increased temperatures initiated a retreat in the length of the glacier over three decades ago. Once in motion, a glacier’s retreat accelerates due to glacial mechanics. It is one of the most rapidly changing glaciers in the world.
Changing Rivers: Iquitos, Peru
Not all change is from humans. There are natural physical processes that continue to shape the Earth’s surface. For example, rivers that experience heavy water flows can be altered through erosion, changing the bends.
Better Perspectives, Better Decisions?
Often, the greatest impacts that occur are out of sight and mind. However, with the increasing availability of satellite technology and improved distribution of images through platforms such as Google Timelapse, the impact of human activity is impossible to ignore.
The bulk of visible changes come from human economic activity, because it is more easily observable on a smaller time scale. However, it’s also worth remembering that there are still many natural processes that take generations, if not thousands of years to affect change.
It is one thing to hear the facts and figures of humankind’s impact on the environment, but to see the change is a whole other story.
