Irrigation with Seawater

The new system will enable people without access to fresh water to irrigate their crops

A new system which allows food crops to be irrigated with seawater will solve global problems of food production, according to researchers at the University of Surrey, UK. "97.5% of the world's water is salty and not usable for the great majority of agriculture," says Professor Adel Sharif, team leader. "With this approach, there is no need for investment in genetically modified crops or ongoing treatments for the soil. The technology will be accessible and will genuinely solve the problem for people without access to fresh water for agriculture."

The low-cost solution, which makes seawater irrigation on a large scale a realistic and sustainable solution to food supply problems, does not require high pressure pumps or expensive distillation units. Instead, the new approach makes use of the natural process of evaporation alongside a membrane designed to retain the impurities in the water, including the salts, allowing only pure water to reach the plants.

The project has built on Professor Sharif's work on Manipulated Osmosis Desalination (MOD), which is used in Gibraltar and Oman to produce drinking water for human consumption. MOD is currently the leading technology for desalination, reducing energy use by up to 30 per cent compared to conventional desalination plants, chemical consumption and the carbon footprint.

From water rights and desalination treatment processes to community-scale sustainable technology, the University team is continuing to work alongside governments and disaster relief NGOs worldwide to improve water for drinking, sanitation and agriculture.

Dr. Adel Sharif, University of London Professor has the Queen Medal for scientific achievement invented a new desalination system.

Dr. Sharif has been special advisor of water for Amir of Qatar.

In Oman there is a Desalination Plant which is built with Dr. Adel Sharif  technology.

The world has become a greener place than it was 20 years ago, largely thanks to China's reforestation efforts that are ambitious enough to have a significant impact on the global mission of cutting carbon emissions.

Every March 21, the United Nations (UN) raises awareness of the importance of all types of forests, offering an opportunity for countries to reflect on their afforestation efforts.

China's progress is noteworthy.

A recent Boston University study tracking NASA satellites shows that over the last two decades, "the greening of the planet represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests," with China and India leading the charge.

The study also finds the world is getting greener overall, and China alone accounts for 25 percent of the global net increase in leaf area although the country holds only 6.6 percent of the global vegetated area.

As a country that once suffered severe desertification, China's progress is stunning and marks a significant contribution to the global community.

In 2018, China planted 7.07 million hectares of trees, and the country is home to the world's largest man-made forest.
