Marrakech solved the water riddle — through wastewater

Stephane Dahan's picture
Marrakech, Morocco, 1950s: Situated 160 miles south of Casablanca, and 100 miles inland on the foothills of the Atlas Mountains, the Red City is being supplied as it has been for centuries with water through an intricate, self-sufficient network of “Khettaras” — man-made underground tunnels that captured runoff from the flanks of the Atlas.

Water utilities in Africa: How will they cope with a rapidly growing, thirsty population?

Caroline van den Berg's picture
Africa’s population is growing fast. Very fast. Sub-Saharan Africa is currently home to more than 1.2 billion people, and it is estimated that another 1 billion will be added by 2050. Economic and political instability, climate change and overall decline of employment in agriculture has accelerated urban migration. In 2016, almost 40 percent of the population in this region was living in cities compared to 31 percent in 2000.

Building institutional capacity for rural sanitation: India’s Uttar Pradesh State

Uttar Pradesh (UP), India’s most populous state with about 200 million people, has historically not performed well on sanitation. According to census figures from 2001 and 2011, the proportion of rural UP dwellers with a toilet increased slightly during the first decade of this century. However, the population grew as well, meaning that, overall, 13 million more people were defecating in the open in 2011. 

How to test water quality? Here are some low-cost, low-tech options

Jessica Anne Lawson's picture
Sustainable Development Goal 6 (SDG6) calls for “universal and equitable access to safe and affordable drinking water” by 2030, which is quite different from access to an “improved” water source, which has been our primary focus with the Millennium Development Goals. This makes water quality monitoring essential: how can we assess progress towards #SDG6 without knowing whether water is safe to drink?

Pulling the chain: Business solutions for managing human fecal waste

To understand why innovation in fecal sludge management matters, ask yourself this: In 15 years, when almost 5 billion people are using on-site sanitation, solutions like pit latrines and septic tanks, what will the world do with all the fecal waste? About half that many people use onsite sanitation today, and we already have a hard time keeping up.

Charting a path to valuing the world’s most precious resource

Willem Mak's picture
Most people agree that water is an extremely valuable resourcefor farmers who depend on it to grow crops, for factories that need it to cool machines and spin turbines and, of course for life itself. But unlike most other valuable resources, it’s hard to place a price on water. The very fact that water is so important to people, economies, and the environment means that it is tough to even agree on a common way of valuing it.

Chickens don't use toilets: Why managing animal feces helps children grow taller

Derek Headey's picture
Those who have tried toilet training a pet dog or cat know that it is a difficult proposition. How about toilet training a flock of 30 chickens?

“Why would I want to?” Because in poor countries, chickens are everywhere, they are pooping wherever they want, and chicken feces is dangerous for young children.

Water, the economy, and development: New insights on a complex challenge

Scott Michael Moore's picture
In the World Bank Water Practice, we often talk about how issues like flooding and droughts threaten our mission to end poverty and boost shared prosperity. But how much do we actually know about how these floods and droughts — "water shocks" — impact farmers, firms, and communities? Perhaps adaptation in the economy has limited such impacts. Or maybe policies have led to economies being more vulnerable to such shocks.

Testing water quality: When labs don’t work

Pratibha Mistry's picture
Drinking water utilities, water resource management agencies, and environmental regulators across the world are required to establish laboratories to test water quality. Proper testing ensures that water is safe for its intended use, whether that be drinking, bathing, fishing, watering crops, or sustaining ecological health. Yet we routinely find poorly-functioning analytical labs.

Yehude Simon's picture
The Water Cartoon Calendar is definitely one of the most unconventional World Bank products. You won’t find anything else like it. If this is the first time you are hearing about it, the Water Cartoon Calendar is an illustrated calendar produced since the year 2000 by the Water and Sanitation Program. It features colorful cartoons depicting water related topics, combined with a mild touch of humor.
