Agroforestry Systems: A Systematic Review Focusing on Traditional Indigenous Practices, Food and Nutrition Security, Economic Viability, and the Role of Women

This study aimed to identify from the literature review whether agroforestry systems have been an agricultural practice adopted by indigenous peoples for income generation and food and nutritional security. For this, a systematic review was conducted in the period from 2010 to 2020 of 92 articles, dissertations, and theses. Thus, it is found that agroforestry practices are traditional indigenous forms of farming that provide food security, income generation, and medicines, in addition to preserving biodiversity. Indigenous agroforestry is fundamental to indigenous culture, strengthening spiritual practices and the relationship with nature. Women have vital importance in the management of agroforestry practices because, through this productive practice, they ensure the food consumption of the family, besides generating income. However, women still face many difficulties in the countryside because their working hours are longer than those of men; besides not participating in decisions on the choice of species and form of management, in some countries, they still face difficulty accessing and owning land. The studies provide evidence on the economic viability of agroforestry systems. However, research gaps are identified that verify the economic and financial analysis of agroforestry models, which address the concerns of indigenous communities, aiming at food security. These analyses are essential for the implementation and continuity of the production system.
