Assessing Groundwater Withdrawal Sustainability in the Mexican Portion of the Transboundary Santa Cruz River Aquifer

The impact of climate uncertainties is already evident in the border communities of the United States and Mexico. This semi-arid to arid border region has faced increased vulnerability to water scarcity, propelled by droughts, warming atmosphere, population growth, ecosystem sensitivity, and institutional asymmetries between the two countries. In this study, we assessed the annual water withdrawal, which is essential for maintaining long-term sustainable conditions in the Santa Cruz River Aquifer in Mexico, which is part of the U.S.–Mexico Transboundary Santa Cruz Aquifer. For this assessment, we developed a water balance model that accounts for the water fluxes into and out of the aquifer’s basin. A central component of this model is a hydrologic model that uses precipitation and evapotranspiration demand as input to simulate the streamflow into and out of the basin, natural recharge, soil moisture, and actual evapotranspiration. Based on the precipitation record for the period 1954–2020, we found that the amount of groundwater withdrawal that maintains sustainable conditions is 23.3 MCM/year. However, the record is clearly divided into two periods: a wet period, 1965–1993, in which the cumulative surplus in the basin reached ~380 MCM by 1993, and a dry period, 1994–2020, in which the cumulative surplus had been completely depleted. Looking at a balanced annual groundwater withdrawal for a moving average of 20-year intervals, we found the sustainable groundwater withdrawal to decline from a maximum of 36.4 MCM/year in 1993 to less than 8 MCM/year in 2020. This study underscores the urgency for adjusted water resources management that considers the large inter-annual climate variability in the region.

Contribución al estudio de la actividad operística en Barcelona (1844-1851): el caso de las sociedades filarmónica y apolínea y del teatro Odeón

En este artículo se presenta y se analiza una faceta de la actividad lírica de la Barcelona del siglo XIX, (período 1844-1851) la correspondiente a la programación operística debida a las Sociedades Filarmónica y Apolínea, al margen de los dos teatros hegermónicos de la ciudad: el Teatro Principal (o de Santa Cruz) y el Gran Teatro del Liceu. Dichas actividades constatan la preeminencia y hegemonía de la ópera italiana en general y de Donizetti en particular.

OS DESAFIOS DO ENSINO APRENDIZAGEM DAS ESCOLAS PÚBLICAS NO PERÍODO PÓS-PANDÊMICO: QUAL O PAPEL DA GESTÃO ESCOLAR?

Este artigo trata-se de um estudo de caso baseado na observação das sequelas deixadas pela pandemia no âmbito educacional. Através de entrevistas realizadas com profissionais da rede pública de ensino de Santa Cruz do Capibaribe, aferiu-se a situação encontrada por toda comunidade escolar no período pós pandêmico e pontuou, diante do exposto, quais são as medidas a serem adotadas para retratar os prejuízos encontrados. A análise dos dados deu-se a partir da análise do conteúdo colhido. Os resultados apontam que o gestor escolar já enxerga os desafios das novas demandas, visando unir forças utilizando-se de uma força-tarefa conjunta em prol dos objetivos e ressaltando que a participação efetiva da família no seio escolar é fundamental para obter sucesso da meta almejada.

Impact of Fires on Key Biodiversity Areas (KBAs) and Priority Bird Species for Conservation in Bolivia

Key Biodiversity Areas (KBAs) are sites that contribute significantly to the protection of the planet’s biodiversity. In this study, we evaluated the annual burned areas and the intensity of the fires that affected Bolivia and its 58 KBAs (23.3 million ha) over the last 20 years (2001–2020). In particular, we analyzed the impact of wildfires on the distribution of Bolivian birds at the levels of overall species richness, endemic species and threatened species (Critically Endangered, Endangered, Vulnerable). We found that at the KBA level, the cumulative area of wildfires was 21.6 million ha, while the absolute area impacted was 5.6 million ha. The KBAs most affected by the wildfires are located in the departments of Beni and Santa Cruz; mainly in the KBAs Área Natural de Manejo Integrado San Matías, Oeste del río Mamoré, Este del río Mamoré, Noel Kempff Mercado and Área Natural de Manejo Integrado Otuquis. The wildfires impacted the distribution of 54 threatened species and 15 endemic species in the KBAs. Based on the results of this study, it is a priority to communicate to Bolivian government authorities the importance of KBAs as a strategy for the conservation of the country’s biodiversity and the threats resulting from anthropogenic fires.

Matilde Díez, La Divina, en Barcelona: El año cómico de 1836-1837

El artículo estudia la trayectoria artística de Matilde Díez en el año cómico de 1836-1837, cuando se ajusta como primera dama en el Teatro de la Santa Cruz de Barcelona. En esa temporada, en la que se gana el apodo de La divina, destaca por sus interpretaciones del repertorio de Dumas, entre otros dramas románticos. Gran parte del mismo estaba traducido por Covert-Spring –José Andreu y Fontcuberta–, cuyas críticas en, entre otros, El Vapor, contribuyeron, junto con una amplia producción poética laudatoria, a consolidar su notoriedad. Heredera escénica de Concepción Rodríguez, desarrolló una dilatada carrera que la convirtió en la actriz de referencia de gran parte del XIX.

City Branding: communication and marketing strategy for an island urban policy

Hoy en día, en la conocida “Sociedad de la Información”, nadie puede dudar de que el marketing y la comunicación dentro de una ciudad turística son cruciales para su existencia y desarrollo. Por ello, la investigación de la marca de la ciudad ha incrementado el interés en la literatura internacional durante los últimos años. El presente artículo se centra en la implementación de una estrategia competitiva de marca de lugar en el caso de Santa Cruz de Tenerife, una capital insular de tamaño medio para explorar el mecanismo central de este fenómeno, desde una perspectiva aplicada y como resultado de la experiencia adquirida en varios proyectos de transferencia de conocimiento liderados por los autores. Específicamente, el objetivo de esta investigación fue identificar y analizar las condiciones actuales que prevalecen en la capital de una isla periférica junto a las posibles colaboraciones entre los interesados. Una extensa investigación bibliográfica sobre el destino y la marca de la ciudad, así como estudios de casos exitosos de otras ciudades, llevaron a la formación del panel de discusión. También se lleva a cabo una investigación cualitativa, desarrollando entrevistas en profundidad con actores locales, líderes de opinión de la Administración pública y emprendedores del sector privado.

Literary Tourism as a Good Practice to Promote Inland Tourism

This study is carried out within the scope of the topic “innovative projects and good practices in inland tourism,” and it will present the case of the Portuguese project Eça de Queiroz Foundation. The Eça de Queiroz Foundation was founded in 1990 on some of the properties left by the 19th-century Portuguese writer, Eça de Queiroz: the Vila Nova farm and house in Santa Cruz do Douro (Tormes/Baião/Portugal), a small inland village in the Douro, a Portuguese region whose landscape is classified as World Heritage. Currently, the organization has several areas of activity, such as cultural, agricultural, and commercial intervention. The foundation also offers numerous products and services that enhance the promotion of Tourism in the Northern Portugal Inland Region.
