Análise do uso de sistemas agroflorestais (SAFS) para recuperação de solos degradados do semiárido: o caso do sítio Jardim de Luz, Crateús-CE

Abstract

Among the cities that make up the backlands region of Crateús, State of Ceará, the municipality of Crateús recorded the largest area of deforestation which, associated with conventional agricultural practices, cutting and burning, in addition to pastoralism, results in degraded areas. Agroforestry Systems (SAFs) have been presenting themselves as allies in the recovery processes of degraded areas. In this sense, the objective of this research was to analyze how SAFs, governed by the principles of Agroecology, can collaborate with the recovery of degraded areas, stimulating the natural regeneration and succession of species, covering the semi-arid region, specifically at Sítio Jardim de Luz, in Crateús-CE. For this, three privately owned SAFs implemented in 2017 were chosen, identified as SAF I, SAF II and SAF III. Through on-site visits, the member species were surveyed and the area of the systems and spacing between rows were measured. To graphically represent the arrangement of the SAFs, AutoCad software was used. The SAFs feature plant biodiversity, native Caatinga species, fruit trees, legumes and forage crops combined. Soil management, the use of biodiverse crops and the conservation of local biodiversity are principles that guide SAF Jardim de luz. It is hoped that this study can contribute to the scientific validation of SAFs, as alternatives that contribute to the recovery of degraded semi-arid soils, and provide greater visibility for the agroecological transition towards sustainability.
