-With the objective of promoting nature conservation, this study proposes an environmental zoning for a protected area that contains part of the remaining Atlantic Forest, a global hotspot that is home to several endangered species of flora and fauna. Conflicting therewith, the protected area is an important tourist attraction in the region and receives many visitors throughout the year. For the zoning preparation, the main factors and constraints of each objective (ecotourism and conservation) are established, and a multicriteria analysis is used, in addition to the MOLA (Multi-Objective Land Allocation) algorithm, to establish the most suitable areas for each use. Extreme protection areas are defined through the intersection of endemic vegetation and soils and altitudes above 1,500 m. Thus, a fraction of 18% is obtained for extreme protection, 59% for conservation, and 23% for areas destined for ecotourism development. The results demonstrate the advantages of using these methods, due to their simplicity, which can support administrators in planning the protected area. The zoning is in accordance with the International Union for Conservation of Nature (IUCN) recommendation because the conservation area corresponds to approximately 77% of the park area, reinforcing the suitability and applicability of the methodology that is used for the zoning of a protected area.Keywords: GIS; Preservation area; Zoning. DEFINIÇÃO DE ZONAS PRIORITÁRIAS PARA A CONSERVAÇÃO E ECOTURISMO EM UMA ÁREA PROTEGIDARESUMO -Neste trabalho foi proposto um zoneamento para uma área protegida, que tem como missão a conservação da natureza e contém parte da Mata Atlântica residual, um hotspot mundial, que abriga diversas espécies da fauna e flora ameaçadas de extinção. Conflitando-se a esse uso, a área protegida é um importante atrativo turístico da região e recebe muitos visitantes ao longo do ano. Para a elaboração do zoneamento, foram estabelecidos os principais fatores e restrições de cada objetivo (ecoturismo e conservação) e utilizouse de uma análise multicritério e do algoritmo MOLA (Multi-Objective Land Allocation) para estabelecer as áreas mais adequadas a cada uso. Foram estipuladas áreas de proteção extrema, através de uma interseção entre solos e vegetação endêmicas e altitudes superiores a 1500 m. Assim, obteve-se uma fração de 18% para as áreas destinadas a proteção extrema, 59% para a conservação e 23% para as destinadas ao desenvolvimento do ecoturismo. Os resultados explicitaram as vantagens da utilização desses métodos dada a sua simplicidade, podendo auxiliar os gestores no planejamento da área protegida. O zoneamento obtido está de acordo com a recomendação da IUCN, visto que a área de conservação correspondeu à aproximadamente 77% da área do parque, reforçando a adequabilidade e aplicabilidade da metodologia empregada para o objetivo de zoneamento de área protegidas.Palavras-chave: SIG; Área de preservação; Zoneamento.

In this investigation, chemical characteristics, higher, lower and net heating value, bulk and energy density, and thermogravimetric analysis were applied to study the thermal characteristics of three algal biomasses. These biomasses, grown as by-products of wastewater treatment in high-rate algal ponds (HRAPs), were: (i) biomass produced in domestic effluent and collected directly from an HRAP (PO); (ii) biomass produced in domestic effluent in a mixed pond-panel system and collected from the panels (PA); and (iii) biomass originating from the treatment effluent from the meat processing industry and collected directly from an HRAP (IN). The biomass IN was the best alternative for thermal power generation. Subsequently, a mixture of the algal biomasses and Jatropha epicarp was used to produce briquettes containing 0%, 25%, 50%, 75%, and 100% of algal biomass, and their properties were evaluated. In general, the addition of algal biomass to briquettes decreased both the hygroscopicity and fixed carbon content and increased the bulk density, ash content, and energy density. A 50% proportion of biomass IN was found to be the best raw material for producing briquettes. Therefore, the production of briquettes consisting of algal biomass and Jatropha epicarp at a laboratory scale was shown to be technically feasible.
