In the last decade, the debate on the governance of water, energy, and food (WEF) has intensified, spurring the emergence of the term "nexus governance." In general, the reduction of trade-offs and construction of synergies between WEF have been placed on the scientific, political, and economic agenda. However, although increasingly used, it is difficult to find a clear meaning and definition of what the term represents. Based on a systematic literature review (SLR), using text-mining and machine learning algorithms, this article investigates what are the conceptual basis of the nexus governance debate, and attempts to clarify the main themes, networks, and gaps within this literature. The analysis is based on quantitative and qualitative methods, combining social network analysis (SNA) and discourse analysis (DA). The results highlighted that twenty-four governance-related concepts support this literature, breaking down into eight groups: water and basin governance; environmental and systems governance; risk and resource security governance; economic governance; global governance; urban governance; integrative and cooperative governance; and "epistemic" and transdisciplinary governance.
A abordagem do nexo urbano corresponde à compreensão e à busca de soluções integradas mediante o reconhecimento das interdependências entre água, energia e alimentos, recursos cuja escassez configura iniquidades em saúde. A hipótese central deste artigo considera que o contexto de escassez corrobora práticas sociais que podem ser sinérgicas ou contraditórias em relação aos desafios da sustentabilidade e dos direitos sociais. O objetivo é investigar sinergias e contradições a partir de práticas sociais mediante o nexo urbano no bairro Novo Recreio, na cidade de Guarulhos, Região Metropolitana de São Paulo, Brasil. A metodologia consiste em um estudo qualitativo e de base etnográfica com referência à Teoria das Práticas, com observações diretas de campo e narrativas. Os resultados apresentaram práticas sociais associadas a falta sistemática de água, precariedades na iluminação pública e no transporte, bem como dificuldade de acesso a alimentos frescos e saudáveis. O estudo das práticas sociais entre sinergias e contradições permitiu verificar que, nesse processo espontâneo de busca de solução para problemas locais, é constatada a necessidade de integrar práticas e saberes locais a políticas públicas e demandas globais. Com isso, denominamos nexos de exclusão a condição periférica de impossibilidade de opções conscientes que permitam orientar conjuntamente a redução da escassez e de iniquidades com alternativas para a sustentabilidade.
Biofuels development in Brazil is a key factor for the environment and sustainable development of the country. Brazil has great potential of available areas and has favourable climate and geography for biofuel production, such as palm oil, soy, sugar cane, etc. This research aims to evaluate palm oil production and expansion in Pará state, in the north of Brazil and also Amazonian territory. Degraded land will be evaluated through remote sensing, because palm oil crops should be placed in these lands, and secondly, expansion scenarios would be created. This research will be a decision support tool for public policies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
