Likewise, in the Amazon basin, climate change hazards of severe droughts and floods   are revealing limits to adaptation among the majority of riverine communities and smallholder farmers with residual impacts associated with losses of income, fisheries and agricultural productivity, as well as affecting non-economic livelihood dimensions, such as the ability to attend school and losses of place and identity through forced migration . Furthermore, the expansion of the agricultural frontier and construction of large dams to supply energy needs in the Amazon basin are amplifying the vulnerabilities and reducing future adaptive capacities of smallholders and the fisheries communities to climate risk . It is expected that a global temperature warming level of 2ºC by 2050 in the Amazon will lead to a significant reduction of water flow in major rivers leading to further food and water insecurity . This is affecting forest- and river-dependent livelihoods in the region .
