SUMMARY:

Climate change represents one of the greatest current challenges to our civilization. Since the 1950s
remarkable environmental changes have been observed in the Amazon, including the increase in the mean
annual temperature and changes in river dynamics, particularly an increase of the incidence of large river
floods and large river droughts. These changes can lead to substantial impacts on socio-ecological systems
and on local livelihoods, affecting directly and indirectly multiple elements of the biological systems and
different activities that are essential for local livelihoods, including fishing, agriculture, extractivism,
hunting and carpentry. A promising way to understand the effects of climate change, and particularly the
increase of extreme weather events, on local livelihoods is through Local Ecological Knowledge (LEK).
LEK comprises the knowledge, practice and beliefs of indigenous peoples and local communities developed
through their long-term interaction with the environment, and its potential to identify and understand climate
change impacts has been increasingly recognized. Here, we investigated the perceived effects of climate
change on the use of natural resources of riverside communities in western Amazonia. We performed semi-
structured interviews with local residents from 24 rural communities spread across a ~ 600 km stretch of the
Juruá River, a major white-water tributary of the Amazon River. We show that local residents from rural
communities in Juruá perceive a vast set of effects of climate changes observed in different systems,
including climatic, physical, human and biological. Local residents associate many of the perceived climate-
related changes to impacts in their livelihood activities, listing the activities of Homegardens / agroforestry
systems, Manioc crop and Andiroba harvesting as those most impacted by climate change. Also, although
some of these impacts are positive, most of them are negative, calling the attention to the vulnerability of
these communities to ongoing and future climate change, as their livelihoods are essentially based on natural
resource management. These impacts should be addressed mitigated through public policies focusing on
economic diversification and training to increase local adaptation capacity and resilience.
