The fascinating world of jellies

They’re stealthy, blubbery and perfectly capable of ruining a beach vacation. In recent years, a spike in invasive, stinging jellyfish swarms in the Mediterranean Sea has been scaring off tourists and affecting local marine life. In Tunisia, an EU-funded program is working with marine biologists and fishermen to combat the menace as well as make it lucrative to catch the creatures as Julia Henrichmann found in her TV report. But the jellies aren’t just a nuisance; they’re also real masters of adaptation, have a variety of uses in medicine and are even good at shutting down nuclear reactors as Jenny Seitz writes in our background article. And, they’re also surprisingly tasty - which is why we’ve even added a jellyfish recipe!

Thailand - stemming the flood

Dry periods turning into drought and heavy monsoon rains marked by floods and landslides. Climate extremes are already a reality in Thailand and are making life difficult for farmers in the Nakhon Si Tammarat province in the country’s South east. They’re getting help from Germany’s international development organization GIZ as well as scientists from Thailand. Using natural materials from waste wood, stones and boulders, farmers are learning to construct small weirs that can help slow the water’s current during flooding. The farmers at the Tha Di river can plan and build these “living fortifications” themselves. Thai scientists are also measuring the speed of the river’s flow and researching marine life to develop further ecosystem-based adaptation measures which are centered on a sustainable use of natural resources.
