Previous issue date: 2008 / Na necessidade atual de solucionar os problemas ambientais das frentes pioneiras da
Amazônia, em relação ao desmatamento e mudança da cobertura vegetal, surge a importância de integrar os conhecimentos de maneira interdisciplinar, entre diferentes formas de saber,para a gestão sustentável dos recursos naturais e bem-estar da população local. Em base a isto, o presente trabalho teve como objetivo analisar o modelo multiagentes TransAmazon, para
identificar suas deficiências e vantagens em relação a aspectos sociais, econômicos,
produtivos e ambientais, e sua vez, apresentar uma proposta para melhorar suas limitações, por meio da inserção da participação social. Isto para a que ferramenta seja utilizada para o
acompanhamento à decisão e permita, num diálogo de saberes, criar reflexões para a
orientação de políticas públicas e para trazer mudanças ambientais. A proposta se baseou na abordagem modelação de acompanhamento (companiong modeling, ComMod), para conseguir representar por meio da associação de vários instrumentos de coleta de informação, as dinâmicas de frentes pioneiras desde vários pontos de vista; e para verificar e complementar o modelo em temas relacionados com a dimensão físico natural (relevo, solos,clima), a dimensão econômica e produtiva (culturas, produtividade, comercialização, valor da terra e as culturas e organização do trabalho), e a dimensão social e cultural (dinâmicas demográficas, relações institucionais, origem, tradições,cosmovisão e representações). A participação dos atores do desenvolvimento permitirá explicar e entender o que acontece no sistema, mas o diálogo será fundamental para identificar variáveis determinantes da durabilidade do sistema e oferecer as alternativas para as mudanças ambientais. _______________________________________________________________________________ ABSTRACT / The spread of pioneer fronts in the Amazon, which results in deforestation and changes to
vegetation coverage, raises environmental problems. To try to solve these problems through a more lasting management of natural resources and for the well-being of local populations, it appears important to integrate the awareness produced by different forms of knowledge,linking them through a interdisciplinary approach. On this basis, the work presented here had as its objective analyzing the multi-agent “TransAmazon” model to identify its strengths and weaknesses in relation to social, economic, productive, political, and environmental spheres. At the same time, it attempted to present a proposal to improve limitations, through greater social participation. Such participation authorizes the collective use of these technical tools to accompany decisions and allow for, in a dialogue of knowledge, the creation of reflections to direct public policies and to bring about changes in practice. The proposal is based on the approach of companion modelling (ComMod). Using a blend of several means of data collection, our approach looks to represent the dynamics of pioneer fronts from different points of view. It allows for the verification and complementation of the initial model in areas
related to biophysical dimensions(landscape, soil, climate), economic and physical
dimensions (type of culture, productivity, marketing, land value, price of cultures and
organization of work), and social and cultural dimensions (demographic dynamics,
institutional relations, origin and traditions of producers, vision and representations of the Cosmos). The participation of development actors will allow for the explanation and better
understanding of the mechanisms at work. Moreover, the dialogue will be fundamental to
identifying the decisive variables of system durability and inventing practical alternatives to improve the well-being of the local populations while being more respectful of the environment. _______________________________________________________________________________ RESUMÉ / La progression des fronts pionniers en Amazonie qui entraîne la déforestation et des
changements de la couverture végétale, soulève des problèmes environnementaux. Pour tenter de les résoudre par la gestion plus durable des ressources naturelles et pour le bien-être des populations locales, il apparaît important d'intégrer les connaissances produites par différentes formes de savoir et de les articuler par une démarche interdisciplinaire. Sur cette base, le travail présenté ici a eu pour objectif d'analyser le modèle multi-agent « TransAmazon »,pour identifier à ses faiblesses et ses avantages en relation aux aspects sociaux, économiques, productifs et environnementaux. Dans le même temps, il s'agissait de présenter une proposition pour en améliorer les limitations, au moyen d'une meilleure participation sociale. Celle-ci autorise l'utilisation collective de ces outils techniques pour accompagner des
décisions et permettre, dans un dialogue des savoirs, de créer des réflexions pour l'orientation de politiques publiques et pour susciter des changements de pratique. La proposition s'appuie sur l'approche de modélisation d'accompagnement (companiong modeling ComMod). Au moyen de l'association de plusieurs instruments de collecte d'informations, notre approche cherche à représenter les dynamiques des fronts pionniers selon différents points de vue. Elle permet de vérifier et de compléter le modèle initial sur des thèmes liés aux dimensions biophysiques (relief, sol, climat), aux dimensions économiques et productives (type de cultures, productivité, commercialisation, valeur de la terre, prix des cultures et organisation du travail), et aux dimensions sociales et culturelles (dynamiques démographiques, relations institutionnelles, origine et traditions des exploitants, vision et représentations du Cosmos). La participation des acteurs du développement permettra d'expliquer et de mieux comprendre les mécanismes à l'oeuvre. D'autre part, le dialogue sera fondamental pour identifier des variables déterminantes de la durabilité du système et pour inventer des pratiques alternatives qui améliorent le bien-être des populations locales tout en étant plus respectueuses de l'environnement.
