Water management has traditionally looked at the physical-chemical measurements which arenot enough to protect the ecosystems in a more detailed watershed management. TheEuropean Union (EU) and Brazil have been attempting to improve their water status by theimplementation of the Water Frame Directive (WFD) and the Brazil's National WaterResources Plan (PNRH) respectively. Despite of many similarities between the policies, theymainly differ in the use of bioindicators. Macroinvertebrates are the most common biologicalindicator used to show disturbances in the water bodies. The aim of this paper is to explainhow macroinvertebrates have been adopted to classify the ecological status of the waterbodies by the Brazilian and EU water policies. In the WFD it was defined the AQEMbiomonitoring program, which uses macroinvertebrates index. On the other hand, the PNRHdoes not require biomonitoring. The use of bioindicators is the main difference between bothwater management policies. It reflects the concept of the water as a resource in Brazil and asan ecosystem in the EU. |
