    Produtividade de citrus na Amazônia Oriental: relações com o clima atual, risco socioambiental relativo aos eventos extremos e modelagem dos impactos das mudanças climáticas futuras
    (Universidade Federal do Pará, 2023-05-31) DIAS, Thaiane Soeiro da Silva; RUIVO, Maria de Lourdes Pinheiro; http://lattes.cnpq.br/9419564604488031; HTTPS://ORCID.ORG/0000-0002-6222-5534; SOUZA, Everaldo Barreiros de; http://lattes.cnpq.br/6257794694839685; https://orcid.org/0000-0001-6045-0984
    In 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.

    Sazonalidade climática regional e a produção dos frutos de açaí (Euterpe oleracea Mart.) no estado do Pará
    (Universidade Federal do Pará, 2014-05-26) DIAS, Thaiane Soeiro da Silva; SOUZA, Everaldo Barreiros de; http://lattes.cnpq.br/6257794694839685
    At the present work were analyzed the relationship between the regional climatic seasonality and the production of açaí fruits representative of 30 cities of Para during a period of 9 years (2003 to 2011). The analysis of correlations confirmed that the standard of precipitation, temperature and humidity interfere on the productivity of açaí fruits in this region, such as the regime of rainy period (months of December to may) associate itself to the low productivity of açaí fruits, while the regime of dry period (June to November) relates with high productivity of açaí fruits. Moreover, it was investigated the impacts of climate changes on açaí fruits production taking into account the future scenarios of regional clime. Throughout the results of a regression model using as predict variables the precipitation, temperature and humidity provided by global model HadGEM2 of IPCC, it is demonstrated that the quantity of açaí fruits(Kg/ha) does not go suffer significative changes in the next 20 years(2013 to 2032).
