These problems add to the challenges that are common to sustainable forest concessions outside protected areas, including insufficient technical capacity, lack of infrastructure and unresolved land tenure conflicts (Chapter 4). Effective management of such areas requires offering the communities meaningful economic opportunities to sustainably use natural resources. Although traditional communities generally have good knowledge about the use of natural resources, they often lack sufficient expertise for sustainable farming, forestry and fishing that meet market demand levels, and generally have limited access to markets (Prates and Sousa, 2014). This lack, in turn, may translate into a risk of increasing the pressure on the natural asset base.
