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)."

Introduction to Glowworm Optimization Algorithm

Overview of the Glow Worm Algorithm Explanation of the original Glow Worm Algorithm The Hybrid Glow Worm Algorithm is an important algorithm to study and understand because of its ability to effectively solve complex optimization problems. By combining the strengths of different algorithms, it offers a flexible and adaptable solution approach that can be applied to various domains. Understanding this algorithm can help researchers and practitioners in developing efficient and effective optimization strategies for their specific problem instances. The original Glow Worm Algorithm is a swarm intelligence-based optimization algorithm inspired by the behavior of glow worms in nature. It involves a population of virtual glow worms that interact with each other and their environment to find optimal solutions. The algorithm uses a combination of local and global search strategies, allowing the glow worms to explore and exploit the search space effectively. Additionally, the algorithm incor

Five new ideas for launching agro-start ups

View the image in original size Agricultural output controls the GDP of a Country. Especially the developing countries largely depend on its agriculture productivity to enhance their socio-economy and livelihood of the local population. Sustaining the profitability of cultivators is one of the major objectives of any government. Water and energy which are the two drivers of agriculture need to be optimally utilized. The uncontrolled and uneven distribution of natural resources, especially water resources, often compromises the agricultural productivity of the water-stressed regions of a country which in turn affects the national GDP of that country. So optimal management of water and also energy resources in an agricultural location can ensure stability and incrementation of GDP of the country. That is why some apps can be developed and offered commercially to the farmers which can help in not only maximization of agricultural productivity but also it will help in the smart managemen
