Environmental problems have been discussed recently in the Japan Society of Erosion Control Engineering (SABO), corresponding with increasing criticism of concrete structures by the general public. Most of the present discussions and SABO works, however, focus on static scenery rather than ecological dynamics. The ideas presented in this paper are oriented to processes which enable ecosystems to maintain connections among a number of biotic and abiotic factors. I propose that SABO is defined as a science which develops the theories and techniques to prevent the erosion disasters without interrupting the diverse processes in natural ecosystems. Maintaining diverse processes is a key issue to ensure productive and species-rich ecosystems. Many papers are reviewed in terms of interactions between geomorphic and biological processes, and summarized in a spatiotemporal framework.
