Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/17123In the context of the agricultural frontier within the Amazonian territory, the production of citrus (lime and oranges) has been relevant in socioeconomic and environmental terms. In this thesis, three different scientific approaches were developed to elucidate: i) the relationships between citrus productivity and climate variability (rainfall and air temperature) and deforestation patterns in eastern Amazonia during the last decades; ii) the socio-environmental risk of citrus productivity due to extreme precipitation events in eastern Amazon; and iii) the impacts of different future scenarios of climate change on the distribution of potential areas of occurrence of the species Citrus sinensis over the Legal Brazilian Amazon. The results showed evidence that natural factors (climate variability and extreme precipitation events) and anthropic factors (deforestation) directly influence citrus productivity in several areas of eastern Amazonia. In addition, projections indicate that climate change can negatively impact the distribution of the main occurrence areas of the Citrus species throughout the Brazilian Legal Amazon.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Agricultura e climaAmazôniaProdutividade de citrusRisco climáticoModelagem ambientalMudanças climáticasAgriculture and climateAmazonCitrus productivityClimate riskEnvironmental modelingClimate changeProdutividade de citrus na Amazônia Oriental: relações com o clima atual, risco socioambiental relativo aos eventos extremos e modelagem dos impactos das mudanças climáticas futurasTeseCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIASINTERAÇÃO CLIMA, SOCIEDADE E AMBIENTECLIMA E DINÂMICA SOCIOAMBIENTAL NA AMAZÔNIA
