A beleza seca: aspectos do paisagismo no semiárido brasileiro.

Abstract

The conservation of scarce water resources in Northeast region of Brazil requires a more efficient management program. The bad rainfall distribution on site, urbanization and periodic droughts intensify the water demand. However, the urban occupation still modifies the spatial morphology without noticing the natural landscaping potential, while seeking to reproduce aesthetic external and different patterns. Therefore, it is necessary the perception of the urgency of minimize the waste of water. Reshaping the landscape through suitable planning and modifications not only help reduce its consumption, but also maintenance costs. Thus, the present work presents more efficient landscaping solutions with regard to water economy and fight against desertification in Brazilian semiarid region. Techniques such as plant sorting due to the water need, elaboration of artificial oasis, using mulches and windbreaks demonstrate efficiency when allied to the survival mechanisms inherent to native vegetation.
