O Pará está em destaque na produção de açaí para comercialização nacional e internacional, movimentando um mercado em constante expansão. Os modelos de microaspersores rotativos variam de acordo com a pressão de serviço, vazão e características de aplicação de água, como precipitação, dimensão das gotas, número de bocais e padrão de distribuição de água. Os microaspersores estacionários (“sprays”) não têm movimento de rotação, mas funcionam de forma similar aos rotativos. Apresentam a vantagem de permitir sua utilização em áreas irregulares, com vazão alta e de baixo custo de aquisição. Neste contexto, o objetivo desse trabalho foi avaliar emissores de irrigação dos tipos microsprays e microaspersores bailarinas no cultivo de Açaí BRS Pai d’Égua, em terra firme, no estado do Pará. O experimento foi realizado no Sítio Boa Sorte, propriedade rural na cidade de Paragominas, estado do Pará. Foi utilizado o delineamento em blocos casualizados com quatro tratamentos, com marcas de microaspersores e de microspray e cinco repetições. O experimento teve um total de 182 touceiras e 546 plantas de açaí. Foram avaliadas as variáveis biométricas de crescimento e o teste de uniformidade de aplicação de água. Não houve diferença significativa dos resultados dos tratamentos avaliados entre as marcas de microaspersores tipo bailarina e microspray nas características das plantas. Os resultados do teste de uniformidade de distribuição de água foram considerados bons para a cultura do açaí. O uso de microspray para os anos iniciais da cultura do açaí pode ser uma alternativa por fornecer água de forma eficiente e de baixo custo de aquisição.

Este artigo busca problematizar a apropriação dos espaços do Hospital Psiquiátrico de Jurujuba, em Niterói/RJ, através da perspectiva dos pacientes. Aponta-se para a possibilidade de uma reflexão que vislumbre as diferentes formas de reinvenção do espaço que se reflete na paisagem interna do Hospital. Para tal, apresentamos uma breve análise dos cartazes produzidos pelos pacientes e fixados nas paredes do saguão de entrada e corredores, tensionando a paisagem manicomial estéril e desumanizada – própria das instituições totais. Dada à complexidade da empreitada, propomos uma linguagem teórico-conceitual renovada, na tentativa de aproximação dos campos da Geografia e Saúde Mental, materializada em alguns conceitos que se articulam para tentar expressar e dar conta de uma análise geográfica da relação entre loucura, sociedade e espaços institucionais.
ESPAÇO, ESTIGMA E SUJEITO: Reflexões na Produção de uma Geografia Social Crítica
Authors: Servilha Mateus de Moraes
Published: February 2025

Este trabalho consiste na produção de reflexões acerca das relações entre estigmas sociais e a produção e vivência espaciais. Iniciamos o trabalho a partir de um diálogo com o conceito de estigma para, em seguida, propor articulações entre o estigma e os processos de valoração socioespacial. Posteriormente, enfrentamos o conceito de sujeito, articulado a debates sobre a identificação, refletindo sobre as possibilidades de aberturas temporais, espaciais e ontológicas enquanto potências para o desenvolvimento humano e condições para a emancipação. Buscamos debater estigmas enquanto valorações sociais centrais nos processos de integração socioespacial, assim como a forma em que diferentes reações aos mesmos podem ser entendidas como produtos-produtoras de diferenciadas práticas socioespaciais. O objetivo deste trabalho é compreender a relevância do estigma enquanto questão para a produção de um conhecimento geográfico social crítico na contemporaneidade.
A “ideologia” no Boletim Paulista de Geografia (1949-2018)
Authors: Del Gaudio Rogata Soares
Published: February 2025

O objetivo desse artigo é analisar o tratamento dado à “ideologia” no Boletim Paulista de Geografia no período compreendido entre 1949 – primeira edição - a 2018. Trata-se de uma análise documental de caráter transversal, tendo por foco artigos que apresentavam - nos títulos, palavras-chave ou resumos -, menção a essa concepção. A partir da seleção dos artigos tendo como premissa a presença do termo ideologia, os artigos foram analisados na sua integralidade, objetivando responder às seguintes questões: quais foram as referências citadas, pelos autores dos artigos analisados, para embasar a discussão desse conceito? Essa concepção encontra-se articulada à discussão proposta nos artigos ou a palavra simplesmente “aparece” no texto? Houve preocupação dos autores dos artigos analisados em explicitar a concepção de ideologia?

O objetivo deste artigo é refletir sobre o processo de construção da identidade da mulher na Comunidade Quilombola Dona Juscelina, que está localizada em perímetro urbano da cidade de Muricilândia-TO, as margens da rodovia TO-222 no norte do estado do Tocantins. A mulher quilombola encontra no seu processo de construção da identidade uma trajetória permeada de dificuldades e resistências e nesse trajeto a partir de suas memórias e territórios ela se reconstrói. Nesta pesquisa utilizou-se de uma abordagem qualitativa através dos seguintes procedimentos: pesquisas bibliográficas, observação participante, depoimentos pessoais com gravações de áudios em entrevistas individuais autorizadas pelas protagonistas a partir do uso de recursos e plataformas digitais respeitando as normas de distanciamento em razão da pandemia da COVID-19. As reflexões analisadas demonstram que a construção da identidade da mulher quilombola é um seguimento de resistência que si inicia na memória e na luta pelo território e se re-constrói diariamente.
Branqueamento do território e colonialidade

Published: February 2025

No ensino de geografia é comum os materiais didáticos justificarem a entrada de imigrantes europeus devido a falta de mão de obra para o trabalho, na medida em que a escravidão no território brasileiro foi abolida. Essa tese, além de não explicar como faltaria mão de obra em um território com grande população negra livre, naturaliza/invisibiliza a política de branqueamento, retirando o teor racista e colonial da gestão populacional e territorial concretizada em políticas massivas de imigração não negra para o Brasil. A naturalização desse discurso acaba por encobrir também outras formas de branqueamento que não são necessariamente focadas no fenótipo. É baseado nesse ponto que este artigo tem como objetivo apresentar caminhos teóricos e metodológicos para trabalhar o conceito de branqueamento do território (SANTOS, 2009, CORRÊA 2013, 2018) como um dispositivo da colonialidade do poder. Pretende-se não só demonstrar como a política de branqueamento foi importante para entender a formação populacional brasileira, como também evidenciar e tensionar o apagamento das múltiplas geo-grafias negras no território brasileiro e os desdobramentos desse conceito na contemporaneidade. Assim, destacamos que este debate é de suma importância para entendermos como os discursos sobre branqueamento realizados principalmente – mas não unicamente - entre 1870 e 1930, se converteram em práticas/dispositivos territoriais e coloniais, que permanecem ainda hoje nos processos de territorialização e desterritorialização de negras e negros no Brasil. A partir da apresentação do conceito de branqueamento, buscaremos trabalhar a concepção de branqueamento do território, demonstrando como esse conceito pode ser apropriado para as pesquisas em geografia e os trabalhos com temas que envolvem de forma direta ou indireta as territorialidades negras.
Considerações sobre as geografias das relações étnico-raciais e as geografias negras no Brasil

Published: February 2025

A Geografia brasileira tem sido provocada, principalmente a partir dos anos 2000, a reconhecer o elemento étnico-racial como constituinte do espaço e, portanto, objeto de estudo da disciplina. Os agentes dessa provocação são, principalmente, um grupo de geógrafos, em sua maioria negros, que, preservando suas individualidades, buscam agir de forma coletiva no sentido de construir uma perspectiva racializada para a Geografia. Tal grupo tem suas raízes na histórica luta dos movimentos negros brasileiros por acesso à educação e, mais recentemente, aos espaços institucionais de produção de conhecimento. Nesse contexto, este artigo apresenta um panorama do que vem sendo denominado de “Geografias das relações étnico-raciais” e “Geografias Negras” no Brasil. Realizamos uma síntese das leituras desenvolvidas nesse campo, apontando as principais perspectivas, abordagens e temas. De forma propositiva, apresentamos uma proposta de agenda para complexificar e ampliar as interpretações das Geografias Negras.
