CLAYTON-BARBOSA, Admilson. Bioengineering using bamboo barriers to erosion control: A qualitative analysis. Polibotánica [online]. 2012, n.33, pp.223-243. ISSN 1405-2768.

This work shows the potential use of bamboo with an alternative to recover the moderate erosion. The technical was applied in southern scarpment of the Serra da Mantiqueira, city of Pindamonhangaba, and claimed as a result to reverse environmental damage caused by the rupture of a water adductor located at 1 700 m altitude, that resulted in the formation of a scar in the hillside forest, with soil and vegetation removal. To reverse the erosion processes created at the site, a new technique was developed using four barriers formed by seedlings of Bambusa multiplex (Lour.) in order to divert the waters and promote the regeneration of vegetation. The planting site was delimited by limiting lawn, with function to keep the bamboo seedlings in a confined space, limiting its growth, ensuring that rainwater did not carry the seedlings before the interlacing of rhizomes, their formation and fixation in the soil. The seedlings of B. mutiplex were planted next to each other, at distances of 10 cm, trying to fill the enclosed area. The interventions, barriers that will promote the stability of the erosive processes. The choice of bamboo as a type natural ecological barrier, favored the drainage of superficial waters and provided the stability of the erosions caused by environmental accidents, and can be considered as an efficient method to contain the erosive processes.
