Orientador: Osmar de Carvalho Bueno / Banca: Elias José Simon / Banca: Sergio Augusto L. Furchi / Abstract: Earth and its forms of life would not be the same without greenhouse effect. Some researchers estimate that without greenhouse effect Earth temperature would be very low, in an average of -32°C e -23°C, and life, as we know it, would have never appeared. The greenhouse effect is a physical proccess by which the presence of atmospheric gases makes Earth to maintain higher balanced temperature than it would have if they were absent. The global heating refers to the continuous and large period increasing of this balanced temperature. Thus, the presence of the gases of greenhouse effects is not a problem. The problem appears in its lack of control, making possible the global heating in such a level which global climate would significantly be modified. This overstated global heating risk became higher after Industrial revolution while there was a increase of fossil fuel us in the means of production raising a lot the concentration levels of carbon dioxide (CO2), wich is the greenhouse effect main gas in atmosphere. The Brazilian Climate Changes Forum aims to aware and move society to the discussion and decision making on these problems that arising out of climate change by gases of greenhouse effect, as well as on the Clean Development Mechanism (CDM) defined in article 12 of the Protocol of Kyoto to the United Nations Framework Convention about Climate Change, confirmed by the Brazilian National Congress through the Legislative Decree n° 1, of February 3rd, 1994. The Brazilian Federal Constitution of 1988 emphasizes in its article 225 that everyone has the right to have an ecological balanced environment, a common use and essential welfare to the quality of a healthy life behooving to the Political Authorities and community to defend it in current days and for the future. Therefore, the questioning of global heating loses its characteristics of calling environment scholars... (Complete abstract click electronic access below) / Mestre

Devido às atuais discussões sobre a Reserva Legal, este trabalho tem por objetivo conhecer a distribuição das áreas agrícolas da região em suas variadas explorações, com especial ênfase às áreas de mata natural, comparar os valores municipais com aqueles dispostos no Código Florestal Brasileiro, de forma a analisar o processo de implantação dos 20% de área de florestas em relação à área total agrícola, em nível macro municipal e regional, sem considerar as áreas de cada uma das propriedades agrícolas e nem a bacia hidrográfica às quais pertencem. Os resultados do trabalho, desenvolvido com dados secundários do projeto LUPA da Secretaria da Agricultura do Estado de São Paulo, relativos aos anos 1995/1996 e 2007/2008, mostram que todos os municípios pertencentes à região não possuem áreas de mata natural iguais ou superiores aos 20% da área total e que portanto terão que reflorestar sem finalidade exploratória, a não ser cumprir os preceitos da legislação; que o município de Pereiras apresentou no período de 1996 a 2008 leve involução na área de mata natural; que não levando em consideração possíveis incrementos futuros na área total agrícola, os municípios de Areiópolis e, em seguida, Pratânia, terão de aumentar a taxa de reflorestamento em relação à taxa de regeneração da mata natural efetiva entre 1996 e 2008, visando a atingir os 20% da área total com matas naturais ou com florestas que não venham a ser exploradas e que dentre estas, a maior velocidade deverá ser implementada pelo município de Areiópolis; que o município de Itatinga e, em menor magnitude o de Pardinho terão que empregar taxas de implantação... / The region of Botucatu, Brazil, is traditionally known for its logging industries and has large natural and reforested forests. Due to the considerations on the Legal Forest Reserve, the aim of this paper is to show the distribution of the farming areas in the region and their application – especially natural forests. Also, to compare the municipal values with those stated in the Brazilian Forestry Code in order to analyze the process of implementing 20% of forest area in relation to the total farming area, at municipal and regional levels, not considering the areas of each of the farms nor the watershed to which they belong. The work results – developed from secondary data from the LUPA Project of the State of São Paulo Department of Agriculture, years of 1995/1996 and 2007/2008 – show that all municipalities in the region of Botucatu do not have forest areas equal to or greater than 20% of total area. Therefore, a non-exploratory reforestation procedure will have to be implemented to follow legal requirements. The results also show that the municipality of Pereiras presented – from 1996 to 2008 – a slight regression in the area of natural forest; that the municipalities of Areiópolis and Pratânia will have to increase the reforestation rate over the regeneration rate of the effective natural forest area between 1996 and 2008 in order to achieve the 20% of total area with natural forests or forests which will not be explored – not taking into consideration, though, future farming increments. Still, Areiópolis will have to implement it the fastest. The results also show that the municipality of Itatinga – and, to a lesser extent, the municipality of Pardinho – will need to employ a lower implementation rate than the one verified in the effective regeneration of forests between...
