VIENNA (AP) — The head of the U.N. nuclear agency warned Monday of the dangers of nuclear material falling into the hands of terrorists and urged world nations to apply an agreement meant to minimize such dangers.
Two-thirds of the 89 countries agreeing with the Amendment to the Convention on the Physical Protection of Nuclear Material must ratify it for it to enter into force. Yukiya Amano of the International Atomic Energy Agency says ratification by 11 more nations is needed.
Its application would “reduce the likelihood of terrorists being able to detonate a …’dirty bomb,'” which can spread radioactivity over a wide area and also reduce the risk of an attack on a nuclear power plant, said Amano.
He noted that nearly 2,800 incidents of radioactive material going missing have been reported to his agency since 1995.
In the most recent reported case, the agency said last week that it had been informed by Iraq of the theft of an industrial radiography device in the city of al-Zubair in November.
Experts say the amount of the substance is too small to pose a terrorist threat. But if mismanaged, it could be fatal on exposure over several days, or in some cases as little as a few hours.

Có lẽ, đã đến lúc nên nhìn nhận người địa chủ như một thành phần sản xuất trong xã hội, tương tự như giới doanh nhân, chủ đầu tư, nhà tư bản, chủ tịch tập đoàn… Ảnh: Lê Hoàng Vũ
(TBKTSG) – Hơn nửa thế kỷ qua, tên gọi giới địa chủ, mặc nhiên được xem như một giai cấp gắn liền với bóc lột tá điền, cường hào ác bá, ăn chơi hưởng thụ, dốt nát hợm hĩnh, cấu kết với các thế lực thực dân phong kiến cầm quyền, chống phá cách mạng…
Ngày nay, tình thế kinh tế – xã hội trong và ngoài nước đã có nhiều thay đổi, nhưng quan niệm về địa chủ dường như vẫn chưa thay đổi kịp. Có lẽ, đã đến lúc nên nhìn nhận người địa chủ như một thành phần sản xuất trong xã hội, tương tự như giới doanh nhân, chủ đầu tư, nhà tư bản, chủ tịch tập đoàn… Tiếp tục đọc “Địa chủ hiện đại, tại sao không?”

Summary: There are four billion people worldwide who are affected by severe water scarcity for at least one month a year. That is the conclusion after many years’ extensive research. This alarming figure is much higher than was previously thought.
Sciencedaily – There are four billion people worldwide who are affected by severe water scarcity for at least one month a year. That is the conclusion of University of Twente Professor of Water Management, Arjen Hoekstra, after many years’ extensive research. This alarming figure is much higher than was previously thought. His ground-breaking research was published in Science Advances.
Professor Hoekstra’s team is the first research group in the world to identify people’s water footprint from month to month and to compare it to the monthly availability of water. “Up to now, this type of research concentrated solely on the scarcity of water on an annual basis, and had only been carried out in the largest river basins,” says Hoekstra.
He defines severe water scarcity as the depletion of water in a certain area. “Groundwater levels are falling, lakes are drying up, less water is flowing in rivers, and water supplies for industry and farmers are threatened. In this research, we established the maximum sustainable ‘water footprint’ for every location on earth, and then looked at actual water consumption. If the latter is much greater than what is sustainable, then there can be said to be severe water scarcity.”
More than previously thought
Until now, it had always been assumed in the scientific community that 2 to 3 billion people were affected by severe water scarcity. “Previous research looked at the availability of water on an annual basis, but that paints a more rosy and misleading picture, because water scarcity occurs during the dry period of the year,” explains Hoekstra. In his research, he describes for each place the number of months in a year that people are affected by severe water scarcity. That varies from zero to twelve months per year.
