"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 affected by 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.
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 to generate data of high accuracy of the data. Only open sources and open-source algorithms and analysis tools will be employed to ensure maximum transparency and traceability.
...“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.”...
