South Biodiversity

It does not cause surprise to us that comments that more and more the pressures on the natural surroundings continue increasing with the development, progress of the technology, with ampler uses of potentially harmful processes and with the growth of the populations, being increased the poverty and originating great damages to the planet. The Program of postgraduate of the specialty Management of the quality and productivity of Phases, of the University of Carabobo been seriously has worried and active by this reality and for it has come collaborating with the community, region companies with the participation of communications, seminaries and conferences on this topic, yet what it concerns the environmental contamination, preservation of the atmosphere, with the purpose of to stimulate the commitment of the nation, especially the State in order to give to passage to an environmental culture that allows to protect our natural resources, We know that the finite resources of all the parts of the world as soon as it can do against the accelerated rates of change, that is necessary to create bring back to consciousness on the necessity to preserve the species, that the companies fulfill their social responsibility and that the universities disclose the knowledge and basic information on the reach, repercussions of the biodiversity, ecology, for the guarantee of the survival of the future generations. It is not necessary to forget, that the Earth Summit celebrated by United Nations in Rio de Janeiro in 1992 recognized the world-wide necessity to conciliate the future preservation of the biodiversity with the human progress according to criteria of promulgated sustainability or viability in the International treaty on the Biological Diversity that was approved in Nairobi the 22 of May of 1972, date later declared by the General Assembly of the UN like " International day of the biodiversity German sociologist Elmar Rmpzyk emphasizes that by biodiversity or biological diversity the variability of alive organisms of any source is understood, including the marine terrestrial ecosystems and other aquatic ecosystems among others and the diversity of ecological complexes to which they belong.

Renewable Energy

Although the generation of hidroeltrica energy is classified with renewable energy, the plant construction hydroelectric plants leads great ambient liabilities, as for example, flooding of great areas, promoting alterations in ecosystems of the regions. An example is the plant hydroelectric plant of Tucuru, installed in the Amazonian forest with area of 2.430 km flooded, that it can compromise local biodiversity, extinguish some species, deprive of characteristics some communities quilombolas and aboriginal reserves. The elio-electric generation became enlarged in the world of form sped up throughout the last decade, reaching the scale of gigawatts. One of the factors that limit investments in aeolian enterprises has been the lack of consistent and trustworthy data. The majority of the available anemometric registers is masked for aerodynamic influences of obstacles, rugosidade and relief. The availability of representative data is important in the Brazilian case, that still it did not explore this abundant and renewable resource of expressive form. In function of the ambient impact brought by the conventional sources of generation of electric energy, one has searched to stimulate, the world-wide level, the use of sources you renewed of energy.

In the Brazilian energy matrix, one strong participation of the use of the energy generated for the great hydroelectric plants is observed that, although to be considered as sources you renewed of energy, need the overflow of vast areas, many times of native forests, for water storage. The alternative sources, as of the generation of aeolian energy, still little are used, although the great potential of maritime winds in Brazil, mainly in the coast of the State of the Rio Grande Do Sul, where if it intends to implant a unit of generation of energy with the use of this potential, more necessarily, in the Lagoon of the Ducks. An important geographic complementaridade between the potentials aeolian and hydraulical in Brazil: in general way, the best ones areas for aeolian exploitation place in the extremities of the electrical system, distant of the generation hydroelectric plant. In this situation, the insertion of aeolian energy in the electrical system improvement its performance, diminishing transmission lines. Investments in the order of R$ 200 MI, gifts in this study, considered high, require based economic feasibility studies in necessary information, with details of the initial investments, markets, processes of manufacture, place of implantation, forms of financings, costs of production, hand of workmanship, maintenance and taxation. These aspects had been analyzed in the present work and were concluded favorably to the implantation of the unit, which is sustainable economically. 1.2. OBJECTIVES This work has for purpose to carry through the evaluation of the economic viability of the implantation of a unit of generation of electric energy proceeding from the existing aeolian energy in the Lagoon of the Ducks, in state of the Rio Grande Do Sul.

Agricultural Extension

It presents practical and sustainable solutions for the organization of different spaces. The permacultura is the productive ecosystem elaboration, implantation and maintenance that keep the diversity, the resilience and estabildiade of natural ecosystems, promoting energy, housing and feeding human being of harmonious form with the environment (Mollison et al. 1999 apud Jacintho 2007). Holmgren (2007), through the flower of the permacultura, illustrates the seven necessary fields for a sustainable planning throughout generations: According to Jacinth (2007, p.37), the term appeared in Australia if spread out for the North America and Europe, arriving Latin America and at Brazil in middle of years 80. Today, the continents exist justinian codes of Permacultura in all, in more than one hundred nations. Diverse countries, as Brazil, ' ' they come adopting the Permacultura as agricultural methodology e, even though, schools of all the levels are including the Permacultura in its resume bsico' '.

(TO SOUND, 1998. P. 5) Bill Mollison visits Brazil in 1992 and gives 1 Course of Design in Permacultura (PDC), thus forming, the first Brazilian permacultores that they had had the mission to divulge the method and to create the Justinian codes of Permacultura in Brazil. (PERMACOLETIVO, 2009). Currently, are 14 justinian codes located in the states of Minas Gerais, Espirito Santo, So Paulo, Gois, Mato Grosso of the South, Federal District, Amazon, Santa Catarina, Rio Grande Do Sul and Bahia, that act in the Brazilian territory in different scales. (PERMACULTURA, 2009). These organizations work, through joint actions with the local community and governmental spheres, in such a way to foment the development of practical solutions for the Brazilian society in urban areas how much in agricultural areas. The performance of organizations, as the INCRA (National Institute of Colonizao and the Agrarian Reformation), EMBRAPA (Brazilian Company of Farming Research), DATER/SAF (Department of Assistance Technique and Agricultural Extension of the Secretariat of Familiar Agriculture) and the Agrarian Ministry of Public Works and the Economy, using methods of the Permacultura, promote practical of handling of the natural resources and the impacts of the presence human being more sustainable.
