Meteorological Droughts

The Monterrey Metropolitan Area (MMA) is located in northeastern Mexico in a semi-arid region. As in other areas of the world, prolonged and severe meteorological droughts are recurrent. Meteorological droughts affect the level of dam reservoirs, rivers, and groundwater (aquifers) in the region to the extent they become hydrological droughts which in turn may contribute to socioeconomic droughts. The recent dry event (2011–2013) in northern Mexico severely affected various socioeconomic sectors and may serve as an example of future climatic and hydrologic conditions in this region. Meteorological droughts in northeastern Mexico, mostly induced by anomalously intense subsidence, frequently result in hydrological droughts and intense pressure in the water resources services of the Monterrey Metropolitan Area (MMA), one of the largest cities in Mexico. Landfalling tropical cyclones entering northeastern Mexico historically have alleviated water crises during prolonged droughts. In 2013, the rains from tropical cyclone Ingrid helped to recover water levels in the system of dam reservoirs that provides water to the MMA. However, water management is only one part of a complex socioeconomic system that must respond to the growing demands for water in a region where aquifers are already overexploited. Trends in the atmospheric circulation indicate that droughts in the region may become more severe in the coming decades. Improved water management programs and protocols should be considered in addition to closer reviews of the hydraulic infrastructure. Water transfers from one region to another should be carefully planned because solving a problem in one place may adversely affect another. The use of climate information may be critical to avoidance of water conflicts in the future.

Abstract. Differences between meteorological and hydrological droughts could reflect the regional water consumption by both natural elements and human water-use. The connections between these two drought types were analyzed using the Standardized Precipitation Evapotranspiration Index (SPEI) and Standardized Streamflow Index (SSI), respectively. In a typical semi-arid basin of the middle Yellow River (Qingjianhe River basin), annual precipitation and air temperature showed significantly downward and upward trends, respectively, with the rates of −2.37 mm yr−1 and 0.03 ∘C yr−1 (1961–2007). Under their synthetic effects, water balance variable (represented by SPEI) showed obviously downward (drying) trend at both upstream and whole basin areas. For the spatial variability of precipitation, air temperature and the calculated SPEI, both upstream and downstream areas experienced very similar change characteristics. Results also suggested that the Qingjianhe River basin experienced near normal condition during the study period. As a whole, this semi-arid basin mainly had the meteorological drought episodes in the mid-1960s, late-1990s and the 2000s depicted by 12-month SPEI. The drying trend could also be depicted by the hydrological drought index (12-month SSI) at both upstream and downstream stations (Zichang and Yanchuan), but the decreasing trends were not significant. A correlation analysis showed that hydrological system responds rapidly to the change of meteorological conditions in this semi-arid region. This finding could be an useful implication to drought research for those semi-arid basins with intensive human activities.

Este artigo apresenta a metodologia da Gestão Transdisciplinar de Diversidades, desenvolvida a partir da construção participativa dos Planos de Gestão das Águas e Propostas de Enquadramento dos Cursos D’água, realizados nas Regiões de Planejamento e Gestão das Águas dos rios Verde e Jacaré; Paramirim e Santo Onofre; e Salitre, na região Semiárida do estado da Bahia, no nordeste brasileiro. A partir do olhar transdisciplinar são projetadas reflexões sobre as experiências de participação social na construção dos referidos Planos, observando as contribuições da transdisciplinaridade e da educação no desenvolvimento de metodologias promotoras do diálogo, mediadoras de conflitos e construtoras de processos participativos compartilhados. A Gestão Transdisciplinar de Diversidades ressalta a percepção complexa e dialógica das relações nos processos participativos, valorizando o reconhecimento das convergências e divergências em um determinado território. As convergências fortalecem o grupo, favorecem os pactos, a prevenção de conflitos potenciais e a mediação de conflitos. Este artículo presenta la metodología de la Gestión Transdisciplinaria de Diversidades, desarrollada a partir de la construcción participativa de los Planes de Gestión de las Aguas y Propuestas de Encuadramiento de los Cursos de agua, realizados en las Regiones de Planificación y Gestión de las Aguas de los ríos Verde y Jacaré; Paramirim y Santo Onofre; y Salitre, en la región semiárida del estado de Bahía, en el nordeste brasileño. A partir de la mirada transdisciplinaria se proyectan reflexiones sobre las experiencias de participación social en la construcción de dichos Planes, observando las contribuciones de la transdisciplinariedad y la educación en el desarrollo de metodologías promotoras del diálogo, mediadoras de conflictos y constructoras de procesos participativos compartidos. La Gestión Transdisciplinaria de Diversidades resalta la percepción compleja y dialógica de las relaciones en los procesos participativos, valorizando el reconocimiento de las convergencias y divergencias en un determinado territorio. Las convergencias fortalecen el grupo, favorecen los pactos, la prevención de conflictos potenciales y la mediación de conflictos. This article presents the methodology of Transdisciplinary Diversity Management, developed from the participative construction of the Water Management Plans and Water Frameworks, carried out in the Regions of Planning and Water Management of the Verde and Jacaré rivers; Paramirim and Santo Onofre; and Salitre, in the semi-arid region of the state of Bahia, in northeastern Brazil. From the transdisciplinary perspective, reflections on the experiences of social participation in the construction of these Plans are projected, observing the contributions of transdisciplinarity and education in the development of methodologies that promote dialogue, conflict mediators and constructors of shared participatory processes. Transdisciplinary Diversity Management highlights the complex and dialogic perception of relationships in participatory processes, valuing the recognition of convergences and divergences in a given territory. Convergences strengthen the group, favor pacts, prevent potential conflicts and mediate conflicts.
