SUMMARY:

Reef environments are sensitive ecosystems affected by global change (global warming and ocean acidification) and local processes (eg fishing and eutrophication). It is commonly assumed that one coral reef is healthier (or worse) than another based only on current references, which is a biased assumption known as the shifting baseline, common when there is little or no past information on ecosystems and species. The few records of recent coral reef states give us an idea of how rapidly these ecosystems are changing and suggest that the longer we need to go back in time to detect when specific changes have taken place, the more we need to rely on the memory of stakeholder activities, due to lack of past scientific information. This is especially important for developing countries, where marine research is relatively new. We assess changes in the maritime landscape of Brazilian reefs by interviewing key stakeholders who make different uses of these ecosystems, such as fishermen, divers and researchers. We also seek to understand the convergence of information about reef environments among stakeholders. Stakeholders noticed a general decrease in the number of reef fish along the coast. There is a common perception among stakeholders that local processes such as fishing and marine debris have a stronger effect on Brazilian reefs than global processes such as warming and acidification. However, not all perceptions are negative, as respondents also believe that sea turtle populations have recovered and increased off the Brazilian coast. By harnessing users' memories, we seek to recover part of the past of Brazilian reefs to understand current changes and predict future ones in these ecosystems, building a solid knowledge base to support reef conservation.
