  • Three-dimensional soil landscape modeling: A potential earth science teaching

    Three-dimensional visualization is helpful in understanding soils, and three dimensional (3-D) tools are gaining popularity in teaching earth sciences. Those tools are still somewhat underused in soil science, yet soil properties such as texture, color, and organic carbon content vary both vertically and horizontally across the landscape. These properties can be realistically modeled and ...

  • Revisiting Earth Day

    The 37th annual Earth Day will be celebrated in the United States on April 22, 2006. The purpose of the first Earth Day—in the words of one of its founders—was “to inspire a public demonstration so big it would shake the political establishment out of its lethargy and force the environmental issue onto the national political agenda.”1 Some would argue that this should still be the ...

  • How Secular Stagnation is costing the earth

    A stagnating West, including the USA, the EU and Japan, is the subject of much economic conjecture. Secular stagnation, as suffered by Japan since 1990 is beginning to infect the rest of the developed world. Conventional economists and other commentators have shown signs of becoming panicky ...

  • Managing oceans with sound science

    Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air ...

  • Sustainability science: an ecohealth perspective

    Sustainability science is emerging as a transdisciplinary effort to come to grips with the much-needed symbiosis between human activity and the environment. While there is recognition that conventional economic growth must yield to policies that foster sustainable development, this has not yet occurred on any broad scale. Rather, there is clear evidence that the Earth’s ecosystems and landscapes ...

  • The dangers of separating science and environment

    We need to figure out a better way to communicate science that balances technology and nature. Does the natural world have any relevance to modern science? Of course it does; but sometimes it seems like that’s not the case. This is a myth perpetuated directly and indirectly through media, policy decisions, academic disciplines, even some science engagement initiatives: ...

    Written by Leda Zimmerman.You can read the original new in MIT NewsIn 2010, after a decade of meticulous preparation, Daniel Casey and an MIT team finally ran their experiment. The world’s largest laser struck a millimeter-sized target, and in less than a second, it was ...

  • The condition of China's Rare Earth Magnet Industry

    The development of rare earth industry is really fast since about 1970s with the development of semiconductor industry, as rare earth materials are used widely in semi-conductor industry. As the global top supply country of rare earth materials, China started to mining and manufacturing of rare earth since 1970s. In about 20 years, rare earth from China had taken about 80% of global market. And ...

  • Pavel Kabat: Bringing science to the SDGs

    Scientists can be very good at creating new knowledge in a specific topic area, then dropping it with a thud into policy-makers’ laps, trusting they will figure out how to use it to solve problems. Not so fast, says Pavel Kabat, director general of the International Institute for Applied Systems Analysis, a 43-year-old international organization that brings researchers ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • Science for sustainable development: implementing the Rio agreement

    Six years after the UN Rio Conference on Environment and Development, an effort to give a new boost to its implementation in the field of science was made during the Sixth Session of the Commission on Sustainable Development (CSD6, held in New York in April 1998). This paper recalls the context and content of Agenda 21, the main programme of actions for sustainable development adopted during the ...

  • Sustainable water resource management: the science behind the scene

    Working in the field of research is—in very many respects—challenging and intriguing. In fact, we as researchers are eager to challenge the unknown although we never can reach the ultimate truth. The most we can hope to accomplish is to draw, on the basis of new evidence and understanding, a model of the world that brings us closer to reality than any previous model. Progress along this road is ...

  • Getting past the science of climate change debate

    Like many in my profession, I have grown weary of the divisive and polarized debate over the science of climate change that has been such a disruptive force in recent years. This debate is too often carried out in extremes: Either you believe, or you don't. There appears to be no middle ground. And the uncertainty about whether climate change is caused by human activity or is an unavoidable ...

  • Managing the Earth from Space: Satellite and sensing technology in water management

    Approximately 200 miles above the Earth’s surface, two satellites circle the planet, always between 106 and 193 miles apart. But while these twins—called Gravity Recovery and Climate Experiment (GRACE)—live in space, they’re providing invaluable assistance in managing natural resources on the ground. GRACE has created a unique picture of ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • NASA Science Zeros in on Ocean Rise: How Much? How Soon?

    Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future. Members of NASA's new ...
