SYSTEMATIC REVIEW: THE MAIN METHODS OF RESTITUTION OF DEGRADED AREAS IN THE CERRADO

Abstract

The Cerrado occupies 24% of the Brazilian territory, half Amazon extension, and despite having the richest flora among the world’s savannas, it has been suffering deforestation rates as same as Amazon. Consequently, it is estimated that 57% of Cerrado is degraded. In this context, the present paper aimed to accomplish a systematic review of the last 10 years which answered the following question: “what are the main methods of restitution of degraded areas in the Cerrado?”. Therefore, the methodology was divided into 5 stages: papers identification in the research platform Google Scholar; title screening to exclude duplicates; variable eligibility; inclusion and analysis. Within the 44 analyzed papers, the biggest amount of publication occurred in 2011. Distrito Federal, Minas Gerais e Mato Grosso do Sul were the states with more publications. The most studied Cerrado physiognomic vegetation was the Cerrado sensu stricto. Active restitution was the most abundant. 80% of the papers were labelled as restoration and the rest as recovery. Based on this study it is conclude that the most used restitution method in the Cerrado degraded areas was the active restoration with drift planting and direct seeding.
