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)."

M.Tech in Hydroinformatics Engineering at NIT Agartala: Building the Next Generation of Water Intelligence Specialists

Why Hydroinformatics — and Why Now India is facing a water crisis of compounding proportions. Erratic monsoons, receding groundwater tables, increasingly severe floods, and the pressures of rapid urbanisation have made water resource management one of the most urgent engineering challenges of our time. At the same time, the arrival of machine learning, big data, IoT sensor networks, and geospatial intelligence has created an entirely new toolkit for tackling these problems — if only enough engineers know how to use it. That is the promise of Hydroinformatics Engineering: a discipline that fuses hydrological science with the power of modern computation, data science, and artificial intelligence to model, predict, and manage water systems with a precision that was simply not possible a decade ago. NIT Agartala, an Institute of National Importance under the Government of India, has launched a 2-year full-time M.Tech programme in Hydroinformatics Engineering to train exactly these speciali...

“Lighting the Countryside: A Review of Electricity for the Farm”

“Lighting the Countryside: A Review of Electricity for the Farm” is a clear, engaging reflection on how a 1915 manual about farm electrification still speaks to today’s distributed energy and rural development debates. hydrogeek.substack +1 Core focus of the review The review introduces Frederick Irving Anderson’s “Electricity for the Farm: Light, Heat and Power by Inexpensive Methods from the Water Wheel or Farm Engine” as a practical, narrative-style manual aimed at early‑20th‑century farmers with curiosity but little formal training. hydrogeek.substack +1 It highlights how the book shows farmers using small streams or farm engines to generate electricity for lighting, heating, and power, replacing smoky lamps and manual drudgery with safer, cleaner energy services. hydrogeek.substack +1 Strengths highlighted The review praises the structure : an opening narrative centered on “Perkins” and his neighbor demonstrates, almost like a case study, how an idle water wheel becomes a 24‑hour ...
