Miho Nomura has been working on marine and riverine pollution by microplastics and plasticizers in some of the most polluted rivers, in central Java, Indonesia. Her work is bridging the gap between environmental chemistry and hydrology and hydraulic. At term, she will be able to predict at what time of the year plasticizers and microplastics…

SABO is the science, engineering and art of sediment disaster risk reduction. It has no real equivalent in the Western part of the world, nor outside Asia. Although its detractor are often criticizing its impact on landscapes and ecological continuity, new solutions are today being developed, and one has to remember that it is a necessary response for island countries that sit on earthquake, heavy rainfalls, typhoons and heavy snowfall regions, even more so because short river system drain steep drainage basins.
