Vol. 048: dos Reys, Marcos Alves: Farming and rural systems analyses in forest margins

Forest zones in the tropics are under pressure because of encroachment of farming systems leading to ecologically unbalanced development as well as creating economic and social problems. This book deals with the multidimensionality of this process. It considers the forest area where indigenous people live, the adjacent savannah region with large-scale agriculture and ranches as well as newly settled smallholders and gives special emphasis to the relationships between them. It analyses the potential of farming systems development in the savannah region to  protect  the forest zones and points out the consequences of not allowing groups other than indigenous people to enter natural reserves. In addition, an analyses of fishermen focuses on the use of water resources in protected forest zones (ecotones). These analyses are much related to risk and uncertainty as well as, to a large extent, to qualitative information. For this reason, the fuzzy theory and respective concepts have been designed and tested. The results indicate that the fuzzy concept applied is not only adequate but also improves our current methodological level in certain sectors. It adds another method of risk analysis and widens the methodological spectrum. The fuzzy concept has also been used for measuring the impact of future development strategies. Those strategies tested deal with economic development eliminating the necessity to enter the rainforest zones and use resources therein.
