Estudo da Sustentabilidade Ambiental do Cultivo Comercial do Bambu Gigante: Produção de Colmos e Brotos

Resumo (EN)

The stuciy of aspects about the environmental sustainability of the commercial scale cultivation of the giant bamboo (Dendrocalamus giganteus) in Brazil to prociuce either *culms or shoots, was possible employing the emergy environmental accounting. The major emergy flow on the cultivation without irrigation is the labor input representing about 35% of all emergy value. On the other hanci, the irrigation water is the main emergy flow for the irrigateci cultivation, representing about 30% of all emergy value. lf the local where the system is placeci or the quality of irrigation water is altereci, the value of Sustainable lnciex significantly changes. The ternary ciiagram enableci to visualize clearly the value of Sustainable lnciex of the cultivation of bamboo shoot anci competitiva fooci. Cultivation of fooci with similar nutrition properties compareci with bamboo shoot: was selecteci to make the comparison: cabbage, green bean, potato anci tomato. The cultivation of bamboo shoot show major environmental sustainability among the cultivations of foocis searcheci. When compareci with the prociuction of pinus wooci, the cultivations of bamboo with prociuction of culms is more sustainable when consiciereci the renewable parts of labor anci electrical energy. lf this consicieration is not macie, the cultivation of pinus presents major sustainability.
