Abstract

The quick eucalyptus expansion together with its big species number and their great adaptability to the most varied ecological conditions lead to the need for studies to identify areas with climate fitness for different species implementation and development. Therefore, this study aimed to verify areas suitability for planting two eucalyptus species in Espírito Santo state, using Geographic Information Systems supported by strategic decision analysis. In the analysis, the data used as decision factors were average precipitation, average temperature, hydric deficit and Espírito Santo’s declivity. These factors were submitted to fuzzy standardization, aggregated and compensated by the Weighted Linear Combination process (WLC), resulting in the final fitness mapping. For the species conflict areas conciliation it was used the module for Multi-objective Land Allocation (MOLA), thus maximizing the land suitability for the purpose. The WLC analysis identified the areas suitability and using MOLA module it was able to solve the suitability conflict between the two eucalyptus species. Great part of Espírito Santo state has high suitability for the species development, and the northwest and part of the northern regions have presented the lower fitness for both eucalyptus species analyzed. Considering the 10,000 km2 most adaptable area to eucalyptus cultivation in the state it was found that the most suitable areas for cultivating both eucalyptus species are located in the mountainous region, part of the south region and near the northeast coast.
