Earth's Water Cycle Is Changing Dramatically, And Much Faster Than We Predicted

"Freshwater cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give us the illusion of certainty. Freshwater will always come from the tap. Won't it?

Unfortunately, that's not guaranteed. Climate change is shifting where the water cycle deposits water on land, with drier areas becoming drier still, and wet areas becoming even wetter."

Software could help to save up to 80 per cent of water used on UAE farms

"The UAE's farmers can now use new software that helps to plan crop planting and also calculate how much water their land will need over a year.

A study carried out over many years to trace the flow of sap in date palm trees showed that farmers are using nearly three times as much water as they need to irrigate their plants.

It found that farmers typically irrigate each tree with about 300 litres of water a day.

However, by measuring the amount of sap flowing in the trunk of a date palm, researchers found they could cut that to 180 litres a day during the summer, and to as little as 60 to 80 litres in winter. This would save up to 80 per cent of the water used on the country's farms."

One Woman’s Mission to Fight Water Scarcity in Africa | Earth.Org - Past | Present | Future

"Dr. Sónia Santos Assunção, an experienced geophysicist with extensive experience in soil assessment, first successfully carried out Geophysical exploration to detect underground water in Ghana in 2016 with the support of Geo Analysis that provided the equipment, and given the straight-forward applicability and efficiency of the technologies she used, she decided to extend her scientific project beyond one country. The geophysicist will soon embark on a one-year journey across the African continent, travelling 24,000km to cross a total of 21 countries – from Cairo to Cape Town and from Cape Town to Tunisia – to evaluate the presence of underground sources of water and to teach locals how to acquire geophysical data (available satellite images and information will be provided by AQUAFUTURE Groundwater consultancy)."

Five most innovative and sustainable water bottles

Cover Feature: Five most innovative water bottles selected by ODM V2 Five most innovative water bottles Water bottles are now becoming smart. Recently launched water bottles have the capability to track your hydration level and can remind you to drink water when the hydration level is below a predefined level. Some water bottles can either increase or decrease the temperature of the water in the container. Some alternatives come with blue tooth speaker/stirrer/fuser/wifi etc electronic devices. Some variation of smart water bottles has the ability to self-purify when needed. Here in this feature, we try to find the most innovative smart water bottles that are available on the eCommerce sites with the help of ODM. Now let us continue with the regular features : News about Sustainability Audi e-tron's used batteries in e-rickshaws by Nunam A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking...

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body, especially dendritic systems like rivers, streams, etc. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration, humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub-basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub-basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impa...

Five project ideas for "Hydroinformatics in Groundwater"

In recent years, advanced soft computation techniques such as Multi-Criteria Decision Making and Geographical Information Systems have been widely used to solve water resource development problems. Hydroinformatics (Hydro means Hydrus or water, and informatics means information science) is a branch of science concerned with the application of advanced soft computation techniques and information and communication technologies (ICTs) to water-related problems. The following are five hydro informatics project topics that can be applied to groundwater problems.
