Between the devil and the deep blue sea

Expansion of coastal cities is accompanied by a decline in the quality of life of the people, which was the reason they moved to the coastal zone instead of bringing growing welfare to the inhabitants.

Many Megacities such as Tokyo (pop. 36.000.000), New York (22.000.000) and London (12.000.000) are found in the coastal zone. Coastal protection measures give a sense of false security and require increasingly expensive infrastructure.

The treatment and cure of these coastal syndromes includes renewable energy, recycled water and solid waste, sourcing locally grown foods and attention to social equity issues, especially in education and healthcare. We also need innovation in "soft" engineering for coastal defense, spatial planning and managed realignment and there are successful show cases for this.

Up to now, governments at all scales, from local to international, have largely failed to seriously implement integrated management in coastal zones. This has placed people at risk of disasters such as hurricane Katrina and the Banda Aceh tsunami. The interconnection of coastal processes with upstream management in river catchment has widely been ignored, causing coastal erosion, lack of runoff, nutrient shortage and subsiding deltas.

The pace of change in general is increasing and regionally we are already seeing both economic and climate-change refugees. In parallel, we see climate entrepreneurs eager to exploit Arctic resources. Climate change is exposing the fragile Arctic coasts and ecosystems as well as their vulnerable inhabitants, who subsist on traditional lifestyles, to increasing risks.

Innovation is needed to solve the widespread problems, if we are to turn the tide of losses. We must enable governance at all scales from intergovernmental engagement to the individual, personal choices that may counteract the tyranny of "small and short sighted decisions".

These are the conclusions of 40 international experts from wide ranging disciplines including economics, social sciences and natural sciences who met for an intensive, 5 day workshop near Oslo, Norway. They came from 6 continents to review the development of coastal zones and society worldwide.

The workshop was organized by LOICZ (Land-Ocean Interactions in the Coastal Zone), a core project of the International Geosphere-Bioshphere Programme and the International Human Dimensions Programme on Global Environmental Change.

LOICZ is based and supported by the GKSS Research Centre, Geesthacht, Germany and the workshop was supported by the Norwegian Institute for Air Research, NILU, and the Research Council of Norway.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
