ABSTRACT:
Nature-Based Solutions (NBS) are alternatives for stabilizing urban slopes with reduced costs and significant performance. Therefore, aiming to propose sustainable and economically viable interventions for vulnerable urban areas in Ilhéus-BA, this study sought to integrate an NBS application methodology. To this end, RTK topographic surveying, Standard Penetration Test (SPT), and numerical modeling in Rocsicence Slide software were carried out. The diagnosis revealed an initial Factor of Safety (FS) of 1.298, characterizing insufficient marginal stability. The main aspects analyzed involved the synergy between bioengineering techniques, highlighting Vetiver grass for deep root reinforcement, palisades and SuperAdobe for mechanical containment, as well as MacMat R3 geomats and coconut fiber biomats for surface protection and splash effect control. Based on the convergence between field data and technical literature, it is concluded that the implementation of this prototype demonstrates the effectiveness of SBN (Structured Biological Networks) as a technically robust and low-environmental-impact alternative to conventional grey infrastructure. The integration of these solutions ensures physical stability and hydrodynamic control, simultaneously promoting climate justice and the social requalification of the territory through the creation of resilient community spaces.
