So far, however, the effects on global production and consumption webs are missing from most assessments. This is a serious deficit, argues Anders Levermann from the Potsdam Institute for Climate Impact Research: “World markets as well as local economies are highly interlinked and rely on global supply chains – adaptation therefore requires a global perspective, not just a local one.”
In a Nature Commentary he proposes a community effort to collect economic data on the new website zeean.net. The aim is to better understand economic flows and to thereby induce a transformation of our supply chains into a stable, climate-smart network that renders our societies less vulnerable to future climate impacts.
“Storms, floods or droughts in one place can have considerable effects all around the world,” Levermann explains. “Take for instance the devastating flood in Thailand in 2011: The local impact was calamitous. Its effect on hard-disk production made it also a global event causing a worldwide shortage for months afterwards.” Flows of materials, communication and energy, their interactions and market dynamics can be subject to climatic extremes – directly but also indirectly via their supply chains. “If the associated risk and vulnerability to climate impacts is to be included into the planning of companies or public institutions, the first step is to identify the vulnerable bottlenecks of our global supply networks,” Levermann says.
Open data and open source algorithms
With the newly launched website zeean.net Levermann aims to kick-start a community effort to generate a global economic networks database of unprecedented comprehensiveness. In order to study the impact of climate extremes, highly detailed information is needed. Similar to the architecture of Wikipedia, any registered and vetted user of zeean.net can enter data about flows between different regional economic sectors, while each piece of information posted will be cross-checked and validated by other users to assess the input quality. The idea is to instigate a community that creates a system of checks-and-balances towards high accuracy of the data. Only open sources will be used and only open source algorithms and analysis tools will be employed to ensure maximum transparency and traceability.
So far, only few research groups around the world compile and use supply chain data. Zeean.net will built on the work of Australian researchers from the University of Sydney, providing information on economic flows between 26 sectors in 186 regions of the world during the past 23 years. With each piece of valid information added, zeean.net will become more accurate and comprehensive, while users see a network evolving that depicts the connectivity of supply chains and enables to identify fragile links. Eventually, the economic data is to be combined with probability assessments of future climate extremes from global and regional climate impact models.
“Our growing insight into climatic extremes needs to be complemented with increasing knowledge about the flows of resources, goods, energy and information that keep our societies running”, Levermann says. “Making this information public might induce self-organized dynamics in our global supply network and will hopefully make our economies more resilient against future climate extremes.”

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
