“…Recent studies in tropical and subtropical regions of Brazil are scarce and mainly use small scale laboratory models and adopt succulent or grass plants in their research, but demonstrate a relevant capacity of VR water management in this geographical region . Arboit et al (2021) used small scale models to evaluate the evapotranspiration and runoff rates in a subtropical climate of Brazil. Results for runoff demonstrate that the species used, Sedum rupestre, did not provide better water retention performances than a roof module without any vegetation.…”
