The cultivating of fish and shellfish in artificial ponds has increased dramatically in the last few decades, apace with the ever greater depletion of fish stocks in the oceans. International aid organizations, working with local governments, have made major commitments to expanding aquaculture in the hope that such activities would alleviate poverty and spur economic growth in these areas. But the Swedish human geographer Daniel A. Bergquist has shown, using Sri Lanka and the Philippines as examples, that a major portion of the local population is excluded from these activities and continue to be just as poor as ever.
"The winners are the local elites," he says.
What's more, aquaculture entails serious consequences for the environment. When mangrove forests are cut down to make way for shrimp and fish ponds, the ecosystem is affected. These environmental problems, in turn, impact aquaculture, and entire harvests can be lost.A large part of the explanation for today's situation, according to Daniel A. Bergquist, can be sought in the methods that are used to evaluate what it really costs to cultivate shrimp and fish. These methods are faulty,
would need to be more than five times higher than it is today for the environment and the local population to receive fair compensation for their input."One contributory factor is found in the faulty global market mechanisms that lead to growing inequities in the distribution of resources, profits, and costs between the northern and southern hemispheres. Aquaculture is a clear example of how the colonization of the southern hemisphere is still going on, finding new avenues via globalization and international trade,"
says Daniel A. Berguist.
His study also shows how it is possible to use alternative methods to bring to light this unfair and unsustainable exchange, through interdisciplinary analysis, comparison, and visualization of the situations in Sri Lanka and the Philippines.
Daniel A. Bergquist's dissertation will be publicly defended at Uppsala University on February 15.

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.
Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
