Throughout the lands of the Persian Gulf, desertification is a fact of life. As a result, the countries of this region import 90 percent of their food supply. A new technology developed by visionary researchers at the Waseda University, in Japan, might have found the solution to this problem. A special absorbent film that require no soil may be able to grow plants more efficiently than soil farming.
The research team, lead by Professor Yuichi Mori, has developed a hydrogel film that can hold 1,000 times of its weight in water. The scientists are already testing these films in 180 film farms.
