WISDOM: GNSS-R based flood monitoring

2012 Workshop on Reflectometry Using GNSS and Other Signals of Opportunity (GNSS+R), 2012
In the last years, due to climate changing conditions severe changes in the Mekong delta in Vietnam have been recorded. The goal of the German Vietnamese WISDOM project is to build an information system for an optimized resource management. One of WISDOM's tasks, is the flood monitoring of the Mekong delta.

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

Oikos, EarlyView.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.
