Resumo: The impact of extreme weather events on the agricultural sector in Jamaica is a reason for concern, as it threatens food security and the livelihood of many small farmers. Considering the most recent projections for a reduction in rainfall, along with higher temperatures due to climate change, there is the need for studies concerning drought at the watershed level, as the phenomenon is more localized in comparison to other events. With this in mind, the aim of this study is to compare meteorological and hydrological drought within the Rio Minho Watershed between 1970 and 2014. Results show periods of wet conditions followed by dry conditions for both meteorological and hydrological data. While meteorological drought dominates in terms of occurrence, hydrological drought demonstrated a longer duration. Results from this study will provide a greater understanding as it relates to the drought conditions and the need for water harvesting.

Considerando las proyecciones más recientes sobre la reducción de las precipitaciones y aumento de las temperaturas producto del cambio climático, es necesario realizar estudios sobre la sequía a nivel de la cuenca porque el efecto de los otros eventos sobre las áreas es mayor en inundaciones que en sequías. Por lo anterior, el objetivo de este estudio es comparar la sequía meteorológica e hidrológica dentro de la cuenca del Río Minho entre 1970 y 2014. Los resultados muestran períodos de condiciones húmedas seguidas de condiciones secas tanto para datos meteorológicos como hidrológicos. Mientras que la sequía meteorológica predomina en términos de ocurrencia, la sequía hidrológica demostró mayor duración. Los resultados de este estudio proporcionarán una mayor comprensión en relación con las condiciones de sequía y la necesidad de la recolección de agua.O impacto de eventos climáticos extremos no setor agrícola jamaicano é motivo de preocupação, pois ameaça a segurança alimentar e o sustento de muitos agricultores. Considerando as projeções mais recentes de redução de chuvas e as altas temperaturas causadas, em grande medida, pelas mudanças climáticas, evidenciou-se a necessidade de estudos que tragam em seu escopo o debate a cerca da seca em nível de bacias hidrográficas, já que o fenômeno é mais localizado que outros eventos climáticos. Com isto em mente, busca-se, nesta pesquisa, comparar a seca meteorológica e hidrológica na Bacia Hidrográfica do Rio Minho entre 1970 e 2014. Os resultados mostram períodos de condições úmidas seguidas de condições secas para ambos os dados meteorológicos e hidrológicos. Enquanto a seca meteorológica domina em termos de ocorrência, a seca hidrológica demonstrou uma duração temporal mais longa. Esses resultados podem contribuir com as reflexões sobre as condições de seca e à necessidade de coleta de água na Jamaica.Universidade Estadual de Londrina2020-01-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3697210.5433/2447-1747.2020v29n1p125GEOGRAFIA (Londrina); v. 29 n. 1 (2020); 125 - 1392447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELenghttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/36972/26740Copyright (c) 2020 GEOGRAFIA (Londrina)info:eu-repo/semantics/openAccessHenry, Sheika Tamara2020-01-04T21:57:34Zoai:ojs.pkp.sfu.ca:article/36972Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2020-01-04T21:57:34Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
