Aliada a outros fatores negativos, como o uso e ocupa??o desordenados, as consequ?ncias t?m desafiado a ci?ncia na busca pelo equacionamento dos problemas socioambientais gerados. Nesse sentido, a Percep??o Ambiental tem sido um instrumento bastante relevante em estudos que tratam das rela??es entre meio ambiente e a??es humanas, por possibilitar an?lises das concep??es, atitudes e valores, principalmente aqueles relacionados ? conserva??o ambiental. Aliada ? Percep??o Ambiental, os Indicadores de Sustentabilidade constituem ferramentas relevantes por possibilitarem mensurar as poss?veis causas e consequ?ncias de problemas ambientais. Dentre os diversos Indicadores de Sustentabilidade, destaca-se o m?todo press?o-estado-impacto-resposta (PEIR), que ? um instrumento anal?tico que permite organizar e agrupar de maneira l?gica os fatores que afetam, o impacto que geram na natureza e na sa?de humana, assim como de que forma a sociedade e o poder p?blico podem intervir para reverter a situa??o causada. Nessa perspectiva, foram estudadas tr?s ?reas de Caatinga no serid? do Rio Grande do Norte: Esta??o Ecol?gica do Serid?, Munic?pio de Serra Negra do Norte; Reserva Particular do Patrimonio Natural Stoessel de Brito, Munic?pio de Jucurutu; e parte da Serra de Santana, Munic?pio de Tenente Laurentino Cruz. Estas constituem ?reas naturais protegidas e n?o protegidas e por isso, est?o submetidas a diferentes formas de gest?o, embora compartilhem semelhan?as socioambientais; ou seja, as comunidades residentes nessas ?reas, est?o submetidas a vulnerabilidades e usam de forma desordenada as potencialidades dos recursos naturais. Nesse Cen?rio, esta tese teve como objetivo geral inserir as comunidades rurais no processo de conserva??o, utilizando a Percep??o Ambiental dessas comunidades, aliada ? an?lise da sustentabilidade dos munic?pios por meio do PEIR. As informa??es sobre percep??o foram obtidas de dados prim?rios e secund?rios de estudos anteriormente realizados em comunidades habitantes do entorno da ESEC Serid?, munic?pio de Serra Negra do Norte e da RPPN Stoessel de Brito, munic?pio de Jucurutu. E, por meio de observa??o direta e entrevistas no formato de formul?rios, aplicados a comunidades rurais do entorno da Caatinga do Munic?pio de Tenente Laurentino Cruz, foram obtidas suas percep??es. Os resultados obtidos demonstraram que os entrevistados apresentam um conhecimento amplo sobre a degrada??o ambiental, suas causas e consequ?ncias, atende um vasto conhecimento sobre os recursos naturais existentes nessas ?reas de Caatinga. A An?lise do Sistema PEIR possibilitou identificar nas ?reas estudadas que, nos munic?pios que abrigam Unidades de Conserva??o, a degrada??o ambiental est? em menores propor??es que naqueles que n?o possuem ?reas protegidas, al?m de demonstrar que o conhecimento das comunidades e a aceita??o destas em rela??o ?s Unidades de Conserva??o, potencializam as a??es que podem ser utilizadas para a redu??o da degrada??o ambiental na Caatinga / Environmental degradation is a global problem that particularly affects areas subject to seasonal climatic variations, such as the brazilian semiarid region, namely the Caatinga Domain. Combined with other negative factors, such as natural resource misuse and disorderly land occupation, the consequences of Environmental Degradation have challenged science in the quest for addressing the resulting social and environmental problems. Accordingly, Environmental Perception methodology, by analyzing the concepts, attitudes and values, (especially those pertaining to environmental conservation) represent an important tool in studies that address the relationship between the environment and human actions. Sustainability Indicators are also relevant tools to assess the possible causes and consequences of environmental problems. Among several Sustainability Indicators available, the PressuresState-Impact-Response (PSIR) method is an analytical tool that permits the grouping of factors affecting sustainability as well as their consequences for nature and human health, and thus indicate mitigating actions for society and the public authorities. From this perspective, three areas of Caatinga were studied in Rio Grande do Norte state: Serid? Ecological Station (ESEC), Municipality of Serra Negra do Norte; Private Natural Reserve Stoessel de Brito (PNRSB), Municipality of Jucurutu; and part of the Serra de Santana, Municipality of Tenente Laurentino Cruz. The areas are both legally protected and unprotected and subject to diferent management protocols, though their share the common characteristic of human misuse of natural resources. In this scenario, this thesis? main goal was to introduce the rural communities into the conservation process, using the results of Environmental Perception of such communities, combined with the analysis of the sustainability of municipalities through PSIR. Information on Environmental Perception was obtained from primary and secondary data from previous studies carried out in the ESEC Serid? and PRNP Stoessel de Brito. Additional data was obtained through direct observation and interview forms applied to rural communities in the Municipality of Tenente Laurentino Cruz. The results showed that respondents possessed a broad knowledge regarding environmental degradation, its causes and consequences for the caatinga biome. PEIR analysis showed that environmental degradation was smaller in countries with protected areas, as compared to those without. The population?s knowledge about environmental degradation and their acceptance of conservation units, as showed by Environmental Perception Analysis, coupled with the results of PEIR, suggest that those attitudes may foster actions aimed at reduction of environmental degradation in the Caatinga domain
