4 How shall we rebuild damaged societies? Rebuild huge levees at huge cost? Spray chemicals to desalinate the rice paddies hit by tsunami? Raze forests to build residential area on higher ground to avoid tsunami? Care to the surrounding ecosystem is necessary not to damage ecosystem services but to build sustainable societies.

17 Soil Microbial

18 The biodiversity and vitality value of soil can be quantitatively evaluated Over 1 triliion bacteria are found in 1 gram of soil. Microbial diversity is indirectly evaluated by scoring how many of 95 organic substances are decomposed. Analysis with 15 min intervals for 48 hrs allows to estimate vitality value of soil.

19 To measure the index, soil suspension tested is injected in 96 small walls on a plastic panel, having 95 different kinds of carbon sources. Degradation reaction of each carbon source is observed as coloring reaction in each carbon source 192 times for 48 hours.
