AGROFORESTRY SYSTEMS ON RURAL PROPERTIES: ECOLOGICAL BENEFITS, ECONOMIC FEASIBILITY AND IMPLEMENTATION CRITERIA

Abstract

Agroforestry systems (AFSs) deliberately integrate trees with agricultural crops and, in some arrangements, livestock, constituting a diversification strategy capable of combining production, environmental conservation and income generation. This article aims to analyze the main ecological and economic benefits of AFSs and discuss the technical criteria that condition their implementation on rural properties, with attention to family farming and the context of southern Brazil. This is a qualitative, exploratory, bibliographic and technically applied study developed through a narrative literature review, incorporating classic works and recent studies on soil quality, biodiversity, productivity, ecosystem services, planning and financial assessment. The literature indicates that well-designed AFSs can improve aggregate stability, water infiltration and retention, nutrient cycling, organic matter, carbon sequestration, biodiversity and microclimate regulation. Economically, the combination of products with different production cycles can distribute revenues over time, reduce exposure to fluctuations in a single commodity and broaden market opportunities. However, benefits are not automatic: competition for light, water and nutrients, initial costs, greater knowledge and labor requirements and delayed returns from perennial components may compromise performance when system design is inadequate. It is concluded that the feasibility of AFSs depends on compatibility among species, environmental conditions, family objectives, markets, management capacity, technical assistance and long-term financial planning.
