Systems

A agroflorestal system is not developed in the office, but yes in the field. An attitude must be adopted to hear the producer, to learn as if to use of the popular culture, to establish a communication fluency. The agriculturists must be seen as co-authors of the work, as agents of the process. The term agroflorestais systems is relatively new, but it corresponds practical the old ones, carried through for traditional populations of entire world, as much in tropical climate as subtropical. What it rescues is the necessity of a new model of development, with a new philosophy? the sustainable development. This development must have base in the potentialities of the proper system, go in favor of the nature and not against it. The used technologies must be simple, practical, of low cost of investment. The systems must be economically and socially viable.

The economic and social support estimates in its inclusion the diversification economic, local industrialization, participation of the local population and improvement of the quality of life. In terms of ecological support the following aspects are vital: the conservation of the natural resources and the intensive use of trees, being that these last ones have basic paper in the ciclagem of nutrients, the hdrico balance and the control of the erosion. Therefore to establish agroflorestal system it is necessary to know the physical unit to be worked and to identify to all its potentialities, especially biodiversity. The espaamento must be questioned which and when to plant, therefore a very great density of plantation will cause minor productivity due to competition for water, light and nutrients. On the other hand, a very great espaamento will be space wastefulness, what it will make the productivity for area also to be low. To determine when plantar it must be led in account will have fire use, what it can make impracticable the simultaneous plantation of others species.

Another factor if to consider is that species exist that need sombreamento. In such a way, the complexity of the agroflorestais systems makes with that advantages and disadvantage in its adoption exist. As advantage it can be mentioned: compensatory action (bigger efficiency in the use of the production factors? water, light and nutrients), minor incidence of harmful plants, greater ecological stability, better feeding for the agriculturist, greater protection of the ground against erosion, greater productivity, better distribution of man power throughout the year, minor variability in the production and minor economic risk. As disadvantage, it can be cited: difficulty of handling of the cultures, difficulty in the planning (bigger complexity due the interactions of the system), eventual greater incidence of plagues and illnesses and lack of research in agroflorestais systems in Brazil. For the consideraes it is observed that the agroflorestais systems are not the magical formulas stop to correct all males of the farming sector of the Amaznia, but represents an instrument importantssimo and a significant advance in direction to the sustainable development. What it is clear, in function of the current knowledge, however, is perhaps that this form of exploration of the land, more than what another one, must be boarded with extreme caution for each region where will occur its adoption.

Urban Climate

Therefore, it can be said that the climate, be more quequaisquer other natural systems, exceeds all the borders natural dasatividades and human beings, influencing in the water, the plants, the fauna and agriculture. It is the performance of these factors and elements that determines the climticasdos conditions places and is responsible for the differences between the landscapes. How much to the climatic factors, as relief, latitude, altitude, distance or proximity of the sea, geographic position and vegetation, soestticos and they influence the climate in lesser degree of intensity, in mesoescala. Quandoa scales of the study becomes local, the topography, the surface of the ground and avegetao starts to be excellent in the alterations of the ambient aspects dostio urban. For the interaction between these climatic components and factors, and considering still the diverse regions of the land, that occurs the formation dosclimas.

2. URBAN CLIMATE EVEGETAO Them plantasformam a specific environment, that has evolved in forms and comunidadesdiferentes, having if adapted to the types of climate, precipitations and ground. The plants influence the climate and the geraldevido urban way in to the influence that exert in urban microclimates, acting in the control solar daincidncia, of the temperature and in the humidity of air, the winds, rains eexercendo a effect moderator of the pollution of air. The vegetation contributes to seobter pleasant an urban ambincia, therefore it protects of the effect of radiaosolar, creating a filter effect. In some cases, them they constitute ebarreiras canals, in which the foliages function as excellent obstacles. The relation between vegetation and temperature of air if of nocontrole of the solar radiation, the wind and the humidity of air.

Ambient Education

Considering the Ambient Education a continuous and cyclical process, the used method to develop this project conjugates basic the general principles of the Ambient Education (Smith, apud Sato, 1995). 2. PROBLEMATIZAO the present project has as objective, to present a proposal of action of ambient education in the process of management of the solid residues to the city hall and the community of the city of Gois-Go. This is situated the 135 km the northwest of Goinia, in the crossing of the highways Br-070 and Go-164 and its area of the City is of 3.118, 8 km (0.91% of the total area of the State). Beyond contributing in the search of a partner-economic growth in sustainable bases, conciliating development and conservation.

The city of Gois possesss a Lixo for final disposal of its solid residues, poluindo courses d water and sources, degrading the environment, threatening the public health and serving as a serious ambient degradante. Through the Ambient Education it is possible to revert to the inadequate disposal of the garbage in the City, the municipal government in set with the community can implant Sanitary Aterro, solution pointed as the most adjusted with respect to final disposal of the Solid Residues, for if dealing with a technology that conjugates basses costs, efficiency and operational easiness, contemplating aspect of the ambient preservation. The garbage played in the place without no care, the lack of supervision for enabled people in order to guarantee maintenance of the minimum ambient conditions and of salubrity was observed in the place. Old course d' water, probably destroyed for the constant transit of vehicle leaving to fall of its dump-cart the garbage before the ousting. Located pollution, the chorume is a liquid of black color with odor ackward and raised potential polluting agent, it is formed in this lixo in result of the fermentation and the exposition of organic rubbishes to intempries.

Natality

The development, for all desired is also the only form pacifies currently known of if controlling the natality and estagnar the demographic growth, education and public politics of magnifying of services come back the defense of the environment, is activities potential of generation, in jobs that have not been explored, not to be of superficial form in Brazil. It disciplines individual for defense of the environment, and collective conscience of the necessity to leave for the future generations, conditions of life, with quality. Ambient education is obligator in all the levels of education of the country. Deforestations the generalized deforestations more concur for the assoreamentos of the rivers, measured for the racial use of waters and the form adjusted to reserve itself water in the subsoil is regularized the outflow of the rivers, projects had been developed has 10 years. In the environment of advanced studies of (VSP) the technology it has acted in the defense of the environment, what really it must occur is an ideological transformation in the agronomy schools, today determined by the prescription, recycling is the promising concept but and the fact most important.

Macrorecycling the macrorecycling is part of the city, and that all the garbage of being processed with sights the reduction of the discardings in aterros, having obeyed in such a way enters the rules of the market, collects selective simultaneous is the next step, when the separate residues are carried in the same trip of the collector, but in separate compartments. The third step is the processing of the two fractions (organic and dry) separately in the center of recycling and destimao of humid with dry garbage for a not culminating fraction. To another one technique is not enough to a good conception, for the great technological turn of the macrorecycling the new concept also backwards in its bulge a proposal institucional, based in the concession of the services for longer periods of 10 the 20 years. Conclusion: It concludes that the nature this each threatened day more, the climate tends if to on account transform into the next century to the effect greenhouse, biodiversity tends if to reduce each time more. Water and animals are in extinguishing and can disappear, everything this occur in way, much sped up, everything this reflect a insensibilidade, development and technology, concept clamorous that the ecosystem restoration includes.

Attitudes

The decurrent problems of the generation of residues in any activity, will not be solved, only under optics of the physics, chemistry or biochemist, also will be decided under the mannering optics. To reevaluate concepts, to eliminate preconceptions and to change behaviors, are conditions important and necessary to plan, to implant, to operate and to monitor any technology to be adopted for the management of solid residues. The changes need to occur, therefore the importance of if establishing relations between administrative, urban, social, sanitary, educational the systems and politicians. The urban solid residues continue being a challenge for almost all the cities Brazilian, and mainly most populous. Of this form, we have of a side the necessity of an improvement technician and the infrastructure implementation; of another one, in the qualification and awareness of the population, co-responsible for the management of the city that we desire. Therefore, the garbage is a problem that must be decided, under the point of view sanitary, educative, social, aesthetic, ambient economic.

Under this optics, the ambient education appears as important instrument of formal and informal formation, promoting the construction of social values, knowledge, abilities and attitudes in the direction to sensetize the citizen and to become it responsible for the conservation of the environment. Knowing of this, it is possible the creation of action and literatures capable to offer today of form simple and detailed the differentiation of the ways, used for the treatment them solid residues, its implantation and its correct use. The ambient education if makes essential for being: A process of recognition of values and briefing of the concepts that lead to develop the abilities and the attitudes necessary to understand and to appreciate the Inter-relations between the human beings, its cultures and its half physicists. The ambient education also develops the practical one of the taking of decisions and for the autoformulaes of behaviors on the subjects related with quality of the environment.

Geographic Information System

Geoprocessamento comes to be the automatized use of information, where in some way she is on to an accurate place in the space, either by means of a mere address or for certain coordinates. The systems are several that are part of the Geoprocessamento, between them which, are the GIS or System of Geographic Information, that comes to be the system that congregates greater capacity of processing and analysis of space data. The use of these systems develops information that allow to take decisions to place in practise action. These systems if apply to any subject that it manipulates given or entailed information to one determined place in the space, and that its elements can be represented in a map, as houses, schools, hospitals, and thus for ahead. Many times the volume of information makes it difficult the quality of the information, but, also the union of the important factors for a made right decision. It is in this aspect that the contribution of the systems of Geoprocessamento enters, and mainly of the GIS. Around world where if it lives, nowadays, where the technology evolves each time more and more, and its evolution is so fast, that, even though the new features that are for flowing, already nor is more new features, the Geoprocessamento would not be different, a time that it makes use of the evolution of the technology, to facilitate the difficulties, and nothing more it is of what the junction of collection technologies, treatment, development and use of georreferenciadas information. ABSTRACT: Geoprocessing you eat the uses of automated information, which is somehow linked you an exact place in space, or through simple address or coordinates certain. There ploughs several systems that ploughs part of Geoprocessing, among which ploughs the GIS or Geographic Information System, which is you be the system that combines to greater capacity will be processing and analysis of spatial date.
