Algal blooms hit the poor of India hard

31.05.2010
The problem of toxic algae is not just confined to the Nordic countries – in India algal blooms are threatening poor people’s access to food and their livelihoods, a problem that has been exacerbated by global warming.

With funding from the Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning and the Swedish International Development Cooperation Agency, researchers from the University of Gothenburg are to attempt to reduce the effects of algal blooms.

As in many other developing countries near the equator, millions of people in India depend on the sea as a source of income and food. Exports of farmed tiger prawns and other aquatic organisms are an important part of the Indian economy, and mussels and oysters are often the main source of protein for many poor people.

Environmentally harmful chemicals
But marine farming in India is beset with problems. When pathogenic bacteria, viruses and toxic algae attack, the farmed prawns are treated with antibiotics, which results in resistance. It is also common for the water in the aquaculture ponds to be treated with environmentally harmful chemicals.
Studying the effects
Global warming is predicted to make harmful algal blooms larger and more numerous, as higher temperatures lead to more precipitation and a greater run-off of nutrient salts into the marine environment. The south-west coast of India is particularly exposed in this respect, and it is here that a research project from the University of Gothenburg is to monitor the impact of climate change on algal blooms, with funding from the Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning.
Environmentally friendly food
The background is that the Indian authorities are investing heavily in developing mussel and oyster farms in the hope that they will be able to increase export revenue and produce an environmentally friendly, protein-rich food for the country’s sizeable population. Systematic monitoring that can predict when and where algal blooms will occur is needed if the investment is to pay off.
Future blooms
Using their own investigations and material from Indian colleagues, Anna Godhe and her team at the Department of Marine Ecology will study how the phytoplankton has changed over the last 50 years – a period when the surface water temperature of the Indian Ocean has risen by 1.5 degrees.

“We want to find out which species are expected to cause future blooms, so that we can see how monitoring can be made more efficient,” says Godhe. “We will also be producing models showing how climate change affects tropical ecosystems, something that has only been done to a very limited extent before.”

Less aid
“I think our research is important, not least because India’s strong growth has meant that aid has been scaled down, at the same time as we have realised that environmental problems extend beyond national borders and are worried that everyone in India will get a car and a fridge. We forget that this is a country that is grappling with enormous infrastructure problems, and that more than 700 million people live on less than a dollar a day.”

Facts
Around 100 marine species emit some form of toxin. These accumulate in filtering organisms such as mussels, which cause illness and, in a worst case scenario, death for anyone who eats them. Other toxins cause damage to fish that are kept in captivity, such as farmed fish.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
