Fragmentos de Mata e PlantaÃÃo de cafÃ: valoraÃÃo dos bens e serviÃos do Ecossistemas / Fragments of forest and plantation of coffee: valuation of the goods and services of ecosystem

Pedro Silveira MÃximo 09 August 2006 (has links)
O pouco que resta do bioma da mata AtlÃntica no Estado de Minas Gerais està representado na forma de fragmentos, como à o caso de ViÃosa-MG, regiÃo considerada de extrema importÃncia ecolÃgica e que vem sendo intensivamente degradada nos Ãltimos anos, pela atividade antrÃpica. Esta paisagem fragmentada deve-se, principalmente a aÃÃes dos produtores de cafà que destroem suas Ãreas de PreservaÃÃo Permanente (APPâs) e Reservas Legais RLâs. Somente no municÃpio de ViÃosa-MG 4000 hectares foram plantados com cafÃ, causando assim, uma reduÃÃo drÃstica das matas nativas da regiÃo, bem como uma reduÃÃo significativa no que os economistas chamam de Bens e ServiÃos de Ecossistema - BSE. Assim, foram selecionados os cafeicultores do PRO-CAFà (OrganizaÃÃo local de cafeicultores), como pÃblico alvo, creditando a tal escolha o fato desse grupo caracterizar o cafeicultor de regiÃo montanhosa. Nesse sentido, essa pesquisa teve como objetivo determinar as principais variÃveis que afeta a percepÃÃo ambiental dos cafeicultores, e valorar monetariamente as matas, tendo em vista que isso pode ser uma estratÃgia Ãnica para preservaÃÃo ambiental. Para tal, foi elaborado um formulÃrio com 33 perguntas envolvendo informaÃÃes sobre caracterÃsticas sÃcio - econÃmicas, o uso da metodologia de valoraÃÃo de contingente (MVC), e do veÃculo de pagamento dos âJogos de Lancesâ que revelou a DisposiÃÃo a Aceitar uma CompensaÃÃo (DAC) na troca de um hectare de cafà por um hectare de mata. Os resultados demonstraram que os cafeicultores possuem uma boa impressÃo sobre a importÃncia dos fragmentos, sendo importante destacar que os entrevistados vincularam a existÃncia das APPâs e RLâs como responsÃvel direto pela provisÃo dos BSEâs. Contudo constatou-se que mesmo cientes dessa importÃncia nÃo tinham uma atitude conservacionista, associando a isso, a falta de uma educaÃÃo ambiental clara e a impunidade. A estimaÃÃo da DAC mostrou que caso o governo esteja disposto a aumentar a provisÃo de mata em 70 hectares, ele deveria despender 254.200 reais por ano, tratando apenas dos cafeicultores vinculados ao PRO-CAFà e 1.147.000 reais por ano caso o governo estivesse disposto a trabalhar com toda populaÃÃo de cafeicultores de ViÃosa, o que representa 314 hectares de mata / The little that still remains of the biome of the Atlantic forest, in the state of Minas Gerais, Brazil, is represented in the form of fragments, which is the case of the county of ViÃosa, a region considered to be of extreme ecological importance and that has been intensely degraded over the last years, due to anthropic activity. This fragmented scenery is due mainly to the actions of coffee planters that destroy its permanent preservation areas (PPAs) and legal reserves (LRs). Considering only the county of ViÃosa 4000 hectares has been planted with coffee, causing in this way, a drastic reduction of the native forest of the region, as well as a significant reduction of what economists call ecosystem goods and services - EGS. Thus, the coffee planters in the PRO-CAFà (organization of local coffee planters) were selected as target public, this choice being credited to the fact that this group characterizes the coffee planters of the mountainous region. In this respect this investigation had as a purpose to determine the main variables that affect the coffee planters environmental perception, and monetarily valorization of the forests, since this might be the a single strategy for environmental preservation. For this a formulary was developed with 33 questions involving information on socio economical characteristics, the use of the methodology of contingent valorization (MCV), and the vehicle of payment of the âoffer gameâ that reveled the willingness to accept a compensation (WAC) in exchange of a hectare of coffee for a hectare of forest. The results show that the coffee planters have a good understanding of the importance of the fragments, being important to stress that the interviewees linked the existence of the PPAs and LRs as the direct responsible for the provisions of the EGSs. However, it was found that even though aware of this importance a conservationist attitude was not perceived, associated to this the absence of a clear environmental education, as well as impunity. The DAC estimate shows that in the case that the government is willing to increase the provision of forest to 70 hectares, they should pay out 254,200 reais (around 116,000 dollars), dealing only with the coffee planters linked to the PRO-CAFà organization and 1,147,000 reais per year if the government should be willing to work with the entire coffee planters population in the county of ViÃosa, which represents 314 hectares of forests. .
