In many cases, declining fish stocks are associated with resource conflicts between artisanal and industrial fishing and among fishing communities (MMA, 2015a). Freshwater distribution is uneven, with the Amazon holding about 70% of freshwater resources. Annual per capita water availability varies from 1 460 m3 in the semi-arid North-east region to 634 887 m3 in the Amazon (GWP, 2013). However, water abstraction rose by more than 80% over 2000-12, reflecting population and economic growth.
