In one of the driest regions of Morocco boardering the Sahara, a German NGO has installed fogcatching nets to harvest fog, which frequently blankets the region. One single square meter of net can produce up to 22 liters a day. The new installation will produce up to 37,000 liters of water a day for several villages in the region.

How does deforestation interrupt the rainwater cycle? And what are the techniques that can be employed to restore this essential cycle? Water retention landscaping is designed to catch and contain rainfall, which permits water and nutrients to penetrate into the land. The best way to save water and restore aquifers is to accumulate water in land and these techniques make reforestation and agriculture possible.

In places around the world aquifiers are being depleted and wells have gone dry. Groundwater, milleniums in the making cannot be replenished to make any significant dent to mitigate the rate of pumping and consumption.
Qatar is a very dry desert nation with no renewable fresh water resources like rivers and lakes. The country is dependent upon desalination, therefore to provide water security for its growing population Qatar is building the world’s largest reservoir.
Although they really look strange, shade balls not only reduce water evaporation and the formation of algae, but also lessens the use of chemicals.
The Fujairah 2 Reverse Osmosis Desalination Plant is part of the largest hybrid desalination plant in the United Arab Emirates and one of the largest in the world. It produces daily 591,000 m3 of fresh drinking water.
Advancements in graphene to reduce swelling and pore size when exposed to water will reduce energy costs for existing reverse osmosis desalination plants and open the door to affordable second generation desalination.
Israel has pioneered the formula to fresh water abundance; conservation, no-waste, no-leaks, re-use of wastewater, drip-irrigation, affordable desalination and water sold at a price to cover costs. As the impacts of climate change and population growth plays out globally, desalination is seen as the only answer, however as Israel has proven there are numerous technologies and policies that are necessary to truely achieve water security.
Thermal desalination efficiencies with heat recuperation and re-use reduces energy imput.
The system employs both membrane and thermal methodologies in the desalination process to produce a more cost effective and environmentally friendly system. Aqualife Global will develop and commercialize the technology.

There are numerous new technologies for desalination in the pipe stream: solar domes in the desert, nanofiber technology membranes and other nanomaterials, which can desalinise sea water in minutes…
The Global Aqua Innovation Center at Shinshu University have developed a robust carbon nanotube membrane that is combined with a reverse osmosis membrane for desalination of seawater. The cost effective new membrane lets more water through more quickly and reduces clogging. The demonstration test began in 2019 at a water treatment facility in Kitakyushu using the new membrane to treat 5.5 tons of seawater daily.
Process developed at MIT could turn concentrated brine into useful chemicals, making desalination more efficient.

Scientists from Norway and Switzerland are developing solar islands to produce methanol from CO2 and hydrogen.
The world’s oceans act as a natural sink for atmospheric CO2, and in a normal cycle the carbonic acid produced from CO2 is neutralized by the thick layer of calcium carbonate on the oceans’ floor. However, that calcium carbonate layer is slowly desolving; unable to keep-up with excessive levels of CO2, which has led to ocean acidity…
Every year, 8 million tons of plastic end-up in the oceans; some end-up in fish and some end-up in you. It is not a problem that will disappear; we need to stop polluting and clean the oceans…
The Ocean Cleanup’s latest vessel, The Interceptor is designed to catch plastic pollution before it reaches the oceans. There are 1,000 rivers globally that have been identified as the major contributors (80%) to ocean plastic and catching the debris and pollution before it arrives in the ocean is an excellent strategy. Ocean Cleanup already has two Interceptors deployed and more vessels on the way…
John Englander, the renowned oceanographer reminds his audience of Professor John Tyndall, who 160 years earlier stood in the same theatre and explained to his audience the ‘greenhouse gas effect’ and the specifics of CO2. The presentation details the effects of a warming climate on sea levels; what to expect and what can be done to adapt.
Lifeless water, oxygen-deprived; killing fish, plant life and corals. The prime culprits: sewage and agricultural runoff. Algal blooms can also create ‘dead zones’.
Concrete is vital for protecting coastlines, however it comes with an environmental cost. ECOncrete looks to change that paradigm with a special concrete that enables sea life to flourish.
In 1970 Lake Erie was declared a ‘dead’ lake. At that time, sewage was identified as the principle culprit, however today, Lake Erie’s principle threat comes from agricultural runoff, nitrogen and phosphorus that feed algae blooms, which can be toxic. To deal with this problem farmers hooked up with professors at Ohio State University to create biological barriers to keep nutriants on the land and out of the water runoff.
