Abstract

Since the 1970s [1], a complex man-nature relationship has been gaining prominence in the great world forums related to global environmental changes. The consequences of landscape transformation worldwide have been increasingly recognized not only by the scientific community, but also by the general population. As the world population continues to grow, there is an increasing pressure on water and land to provide an adequate supply of food and industrial products. Projections indicate that by 2030 the population will be 8.5 billion of inhabitants and in 2050 of 9.7 billion [1]. Lack of successful solutions for the preservation of ecosystems and adequate destination for the waste may lead to serious environmental and socio-economic consequences.
