Land Recovery and Soil Management with Agroforestry Systems

Soils have many ecological functions and provide various ecosystem services including support for global food fuel production. However, FAO reports indicate that approximately one-third of the planet’s arable lands show levels degradation from processes soil erosion, low nutrients, acidification, salinization, compaction, sealing, contamination. These conditions are also found in Brazil where is largely caused by inadequate land management. Worldwide, strategic policies been presented to mitigate this problem, with emphasis on sustainable agriculture. Among them, agroforestry has identified as a viable system mitigating recovering degraded areas. Agroforestry techniques developed tested but still not understood farmers, due their complexity. This study aimed analyze experiences studies reported Australia, some countries Africa, search similarities these complex systems identify possible correlations hypothesis recovery can be enhanced through management using agroforestry.
