Natural products such as medicinal plants, wild food  and resins  have high commercial value and contribute an important source of livelihood in some regions. One in six persons globally live in or near forests, and many depend on forest resources for some of their livelihood and needs, particularly in low- and middle-income countries . The FAO has estimated that in 2011 non- wood forest products, including medicinal plants, contributed over 88 billion USD to the global economy . Greater diversity in local knowledge and Indigenous knowledge of natural resources supports resilience in the face of hazards, especially in environments with high levels of uncertainty .
