Wired. These mini, man-made ‘glaciers’ are helping Himalayan farmers. High up in the Trans-Himalayan region of Ladakh, India, a local scientist named Sonam Wangchuk is creating artificial glaciers to help farmers facing the growing problem of acute water shortages.

These mini, man-made ‘glaciers’ are helping Himalayan farmers

Over the past few decades, glaciers in the region (and in areas around the world) have not frozen sufficiently during the winter months, meaning there is less ice and therefore less meltwater. Many mountain communities rely on glacial melt-water during the dry spring and summer months – including farmers in villages in Ladakh, at around 3,500m above sea level. The decline in glacial meltwater is attributed to climate change, and according to the European Geosciences Union more than 70% of glacier volume in the Everest region of the Himalayas could be lost by 2100. Wangchuk – who also teaches at the Students’ Educational and Cultural Movement of Ladakh Alternative School – initially started his project in the classroom. Image: Share Written by. Bowl-shaped roofs harvest rainwater and promote natural cooling in arid environments.

Water scarcity is felt unequally throughout the world with some regions worse off than others.

Bowl-shaped roofs harvest rainwater and promote natural cooling in arid environments

Iran-based BMDesign Studios addressed their home country’s arid climates with an architectural solution to water shortages called Concave Roof, a double-roof system designed to collect and store rainwater, and promote natural cooling. The Concave Roof was engineered for arid environments, where rainwater collection can be tricky due to higher than average evaporation rates and low annual precipitation. The double-roof system, which includes a domed roof beneath a bowl-shaped catchment area, is designed to “help [make] even the smallest quantities of rain [flow down] the roof and eventually coalesce into bigger drops, just right for harvesting before they evaporate,” said the architects to ArchDaily.

Stacking a concave roof atop a convex roof promotes natural cooling through shade and wind movement between the two roofs. + BMDesign Studios Via ArchDaily Images via BMDesign Studios. Recharging the Mountains. Nepal has always had too much rain or too little.

Recharging the Mountains

But irregular monsoons and a worsening water shortage are emptying villages in the mountains of Nepal. While scientists try to find proof that weather extremes in the Himalaya are a result of global climate change, here in Phulbari village 40km east of Kathmandu the real concern is that there are few men left to till the dry red soil. “At least 10 families have left our village in the last few years and migrated to the cities because of the lack of water,” said Nanu Ghatane, who leads a women’s group here.

Even as farmers sell their land and move out to Kathmandu, people from the city have bought their homesteads as investment. WHAT ARE THE IMPLICATIONS OF THE FUTURE OF WATER FOR BUSINESS? – Unlocking Foresight. Water, water, everywhere, and not a drop to drink, or should it be “not a drop to fill the coffers of business?”


That is the question looming menacingly over the business horizon. “Dwindling water supplies are a greater risk to businesses than oil running out, a report for investors has warned” ( So what does this mean for you? No one foresees the day when this situation will happen, but the way things are, it is a distinct possibility. Water scarcity drives food and beverage producers into action. Africa is showing itself to be one of the continents most affected by climate change, with severe droughts, floods and storms expected to increasingly threaten the health of populations and economies.

Water scarcity drives food and beverage producers into action

The UN’s Intergovernmental Panel on Climate Change (IPCC) - the recognised global authority on climate science – has predicted that Africa will warm up to 1.5 times faster than the global average. Many African countries are already under high levels of water stress, and rain-fed agriculture accounts for 95% of farmed land in sub-Saharan Africa. As climate change, population growth and water pollution increase pressure on freshwater resources, the food and beverage sector, which uses 70% of global freshwater supplies, primarily for growing crops, can play a critical role, by working with farmers to help them manage water more efficiently. Equipping all key suppliers to protect water resources is a vast and complex task, requiring both short and long-term activity. Drought, floods and water stress cost companies $14bn. Droughts, water scarcity and stricter environmental regulations cost businesses a reported $14bn (£11bn) this year, up from $2.6bn in 2015.

Drought, floods and water stress cost companies $14bn

Yet companies still aren’t doing enough to protect themselves from water risks, according to a new report. Compiled by environmental non-profit CDP and released Tuesday at the climate summit in Marrakech, Morrocco, the report approached more than 1,200 of the largest listed companies around the world in sectors exposed to water risk. Just over 600 responded, meaning the $14bn figure is likely to be hugely underreported.

The businesses, which included consumer goods giant Unilever and oil and gas company Suncor Energy, were measured on a number of factors, such as their efforts to track their water use and goal-setting to save water. More than a quarter of the companies said water-related issues, including floods and pollution, had affected their bottom line, typically due to higher operating costs and a disruption in production. Wind-powered Water Seer pulls 11 gallons of clean drinking water from thin air. Uk.businessinsider. Zero Mass Our atmosphere contains approximately 3,100 cubic miles of water — enough to cover the entire planet in one inch of water.


That water surrounds us in the form of vapor — water’s gaseous, evaporated state. We’re usually only reminded of this on especially humid days, but our air can actually be considered a water source. Zero Mass Water, a sustainable water startup, is trying to create an easy, off-grid way for anyone to harvest that liquid with its first product, Source. The world's threatened rivers - in pictures.

Scientists accidentally create nanorods that harvest water from the air. Learning from your mistakes is a key life lesson, and it's one that researchers at Pacific Northwest National Laboratory (PNNL) can attest to.

Scientists accidentally create nanorods that harvest water from the air

After unintentionally creating carbon-rich nanorods, the team realized its accidental invention behaves weirdly with water, demonstrating a 20-year old theory and potentially paving the way to low-energy water harvesting systems and sweat-removing fabrics. The researchers note that ordinarily materials will absorb more water as the humidity in the air around them increases.

But between 50 and 80 percent relative humidity, these nanorods will actually do the opposite and expel water, a behavior they say is not shared by any other material. Below that range, they behave as normal, so the process is reversible by lowering the humidity again. "Our unusual material behaves a bit like a sponge; it wrings itself out halfway before it's fully saturated with water," says David Lao, PNNL research associate and creator of the material. Rainwater-harvesting billboards offer lifeline to India's drought-hit farmers. On the New Airport road in the west Indian city of Pune, five Vodafone billboards are doing more to help the drought-hit village of Pimpri Sandas than the local government.

Rainwater-harvesting billboards offer lifeline to India's drought-hit farmers

The billboards, fitted with tanks, are harvesting rainwater. When the tanks are full, a text message sounds on the mobile phones of a 24/7 collection team and within hours red trucks roll in to collect the water and deliver it to Pimpri Sandas about an hour’s drive away. The idea is simple, but for the farmers of the drought hit village it is life-changing. Since they were set up two months ago, Vodafone’s smart billboards have become a lifeline for about 60 farmers who have been left penniless or in debt after four consecutive years of drought. Nepali Times Buzz. A village in eastern Nepal is emptying because it is just too difficult to find water The cool blue waters of the Tamor flow tantalisingly past the parched village of Kurule Tenupa here in Dhankuta district in eastern Nepal, but villagers have to make multiple trips daily to carry the water up the mountain on their backs.

Salt Water into Drinking Water: World’s Largest Desalination Plant Up And Running. In Brief The plant is expected to produce 627,000 cubic meters of water daily when at full capacity. It currently provides 20% of the country's water needs, and it is expected to provide more. Desalination is a process that is expected to take on more of the world’s ever increasing water demand.

In fact, more and more research is going into finding ways to refine the procedure of turning salt water into drinkable water. However, some have doubted the practicality of large-scale desalination. But it turns out, it may very well be practical. Baths to washing machines: welcome to the (almost) waterless home of the future.

Dry shampoos have been a morning routine game-changer, but DryBath takes hygiene hacks one step further. Claiming to be the world’s first bath-substituting lotion, it is among a number of emerging waterless, or near waterless, household solutions. Launched in 2012 by Headboy Industries, DryBath is a cleansing gel made of antiseptic essential oils, bioflavonoids and natural deodorant Tawas that can be rubbed and left on the skin. It was originally developed for poorer communities facing challenges around limited access to water and lack of basic sanitation. However it is proving most popular with working mums in modern homes.

“It’s our biggest market,” says DryBath’s founder Ludwick Marishane. What will happen if world's biggest companies don't take water seriously? Under the new Sustainable Development Goals, 193 countries have pledged to deliver water for all by 2030. With the UN recently publishing a list of indicators to evaluate progress, now is the time for the business sector to step up and contribute. Why should companies care about water? Data from the US space agency Nasa reveals that 13 of the world’s 37 most important groundwater basins are being depleted far faster than they can be recharged. This has a major impact on business, say water experts. Agriculture accounts for 69% of global water use, with industry claiming a further 19%. We’re running out of water, and the world’s powers are very worried. Could Harvesting Fog Help Solve the World’s Water Crisis?

“There are few places where life is so harsh,” Pablo Neruda wrote, describing his native Chile’s Atacama Desert. “It takes untold sacrifices to transport water there, to nurse a plant that yields even the humblest flower, to raise a dog, a rabbit, a pig.” The Atacama is famously dry, receiving, in some areas, only a few hundredths of an inch of rain per year. Over half the world’s population suffers from ‘severe’ water scarcity, scientists say. The Aral Sea in 2015. Four billion people face severe water scarcity, new research finds. At least two-thirds of the global population, over 4 billion people, live with severe water scarcity for at least one month every year, according to a major new analysis.

Rethinking the water cycle. Three billion people will join the global consumer class over the next two decades, accelerating the degradation of natural resources and escalating competition for them. Groundwater is mostly non-renewable, study finds. The water that supplies aquifers and wells that billions of people rely on around the world is, from a practical perspective, mostly a non-renewable resource that could run out in many places, a new Canadian-led study has found. While many people may think groundwater is replenished by rain and melting snow the way lakes and rivers are, underground water is actually renewed much more slowly. In fact, just six per cent of the groundwater around the world is replenished and renewed within a "human lifetime" of 50 years, reports University of Victoria hydrogeologist Tom Gleeson and his collaborators in a new study published in the journal Nature Geoscience today.
