RESUMO:

The present work deals with a study on the faveleira and the use of the vegetable in the rehabilitation of degraded areas. The objective was to understand the process of rehabilitation of areas of desertification occurrence, through the planting of this plant. The work consists of four manuscripts. The first, classified the faveleira, as a key cultural species (CKS) of the Caatinga biome carried out through the use of a methodology proposed by Cristancho and Vining (2004), with the collaboration of literature review on the vegetation, information collected in interviews and observations in loco in areas with the presence of the vegetable. The relation of the faveleira with five among the seven indicators of CKS proposed, classifies it as being a CKS of the caatinga biome. In the second, we analyzed the perception of residents of the rural area of Seridó about the uses of the faveleira. The study was carried out in rural communities of Caicó and São José do Seridó / RN, where the taxon presents itself in the middle of Caatinga. In addition to previous visits, 57 semi-structured interviews were conducted. To all parts of the vegetable has been given relevance. The use of seeds in the feeding of domestic, wild and human animals and leaves in the feeding of domestic animals was pointed out by 100% of the interlocutors. The third and fourth manuscripts were evaluated the capacity of fixation of the faveleira, in area in process of desertification (APD) and desertified area (AD). In the rainy season of 2009, the study area was defined, through in situ observations, with the collaboration of local farmers. Both are located in the rural area of São José do Seridó / RN. ODP planting took place in March 2009. The seedlings were provided by the municipality. In April 2014, of the 82 seedlings introduced, 65 were alive. AD planting took place in March 2015. The seedlings were produced by local farmers using plastic packaging and by sowing. One year later, among the 60 seedlings planted with each technique, 46 and 56 survived, respectively. The APD and AD of the research survived through grazing. After planting, a layer of stones was deposited around the pits to facilitate the storage of water and other particles. In the microsite of 100% of the pits, it was observed the recruitment of common species in the rainy season and the presence of plants of the surrounding permanent vegetation. The faveleira is a Caatinga CKS, suitable for use in the rehabilitation of degred areas, since with the planting of seedlings with more than four months of birth. It is well suited to semiaridity and has close links with the peasant population.
