Competitividad e innovación en el producto turístico rural de la Región de Murcia

The Region of Murcia has managed to consolidate a rural/interior tourism product which has grown quantitatively, on quality parameters, appearing as an economic function to consider. However, in a complex socioeconomic context as we have nowadays, there is a need to call for ways to increase the competitiveness, sustainability and excellence in destinations and products, and endorse that innovation is a key factor to achieve these objectives. For this, the aim of this paper is making an estimation, looking forward to know the degree of innovation applied to this type of accommodation, through the opinions gathered among an important group of proprietors of rural houses of the regional space, an necessary information for its application to a suitable sectorial arrangement.En la Región de Murcia se ha consolidado un producto turístico rural/interior que ha crecido cuantitativamente bajo parámetros de calidad, convirtiéndose en una actividad económica a considerar. Sin embargo, en un contexto socioeconómico complejo como el actual, se aboga por fórmulas que aumenten la competitividad, la sostenibilidad y la excelencia en destinos y productos turísticos, y en este sentido, la innovación es factor clave para alcanzar estos objetivos. Por tanto, el estudio pretende aproximarse al conocimiento del grado de innovación aplicado a esta oferta turística, a través de los testimonios de un grupo importante de empresarios de alojamientos rurales en la Región, una información necesaria para su aplicación en una ordenación sectorial adecuada

Canais com dupla função de drenagemirrigação na Huerta del Segura (Espanha): uma adaptação planeada da irrigação à arididade e dificuldades de agua

The traditional irrigation established on the banks of the Segura River is the paradigm of the dominance of the environment by social groups. The implantation of irrigation canals (living waters) and drainage (dead waters) made possible a revulsive  transformation of this territory to be colonized. The reuse of drainage flows for irrigation meant reaching the maximum efficiency of use in a semiarid region, making this fact known and the value of this hydraulic heritage is the double objective of this work. To do this, a model of this integral water cycle is approached with the Azarbe Mayor del Norte, which supplies a sector of the Huertas de Murcia and Orihuela, a pattern repeated in other pipelines. The analysis has been based on three complementary sources of information: field work, archival work; finally, the review of the digital cartography provided by the respective management bodies.El regadío tradicional establecido en las márgenes del río Segura es el paradigma del dominio del medio por parte de los grupos sociales. La implantación de canales de riego (aguas vivas) y de avenamiento (aguas muertas) posibilitó una transformación revulsiva de este territorio para ser colonizado. La reutilización de los caudales de drenaje para regar supuso alcanzar la máxima eficiencia de aprovechamiento en una región semiárida, dar a conocer este hecho y el valor de este patrimonio hidráulico es el doble objetivo de este trabajo. Para ello se aborda un modelo de este ciclo integral del agua con el Azarbe Mayor del Norte, que abastece un sector de las Huertas de Murcia y Orihuela, patrón repetido en otras canalizaciones. El análisis se ha fundamentado en tres fuentes complementarias de información: trabajo de campo, la labor de archivo; finalmente, la revisión de la cartografía digital facilitada por los respectivos órganos gestores.L'irrigation traditionnelle établie sur les rives de la rivière Segura est le paradigme de la domination de l'environnement par les groupes sociaux.

Las Huertas de Murcia y Orihuela, la homogeneidad de un paisaje del agua con dos realidades diferentes

El presente estudio analiza los regadíos históricos, Huertas de Murcia y Orihuela, como paradigmático paisaje del agua que sigue vigente desde el siglo IX. La creación antrópica de una precisa y jerárquica malla de canalizaciones riego-avenamiento, en los terrenos marjalencos originales, permitió reutilizar las filtraciones de las tierras regadas para volver a irrigar o abocarlas nuevamente al río, esta práctica creó un regadío eficaz, sostenible y de rasgos similares. Sin embargo, en la actualidad, diversos factores socioeconómicos y culturales, iniciados a finales del pasado siglo y todavía amenazantes, han conducido a su regresión. Una pérdida que se ha concretado en un vertiginoso proceso de distinta naturaleza, debido al crecimiento urbano-periurbano de la capital murciana y al uso turístico-residencial de la vega oriolana por su proximidad a la costa.This paper analyses the historic irrigations of Murcia’s and Orihuela’s Huertas as paradigmatic water landscape in use since the 9th Century. The anthropic creation of a precise and hierarchical irrigation-drainage net in the original swampy terrain allowed to reuse the filtrations of irrigated lands to water again or decant into the river. This practice created an efficient irrigation mode, sustainable and similar in features. However, at this moment, diverse socioeconomic and cultural factors, initiated in the last period of the past century and sill threatening, have caused its regression. A loss, which has led to a vertiginous process of different nature due to the urban and suburban growth of the Murcian capital and the touristic-residential use of the Orihuela’s plain for its proximity to the coast

Sherry wine industry by-product as potential biosorbent for the removal of Cr(VI) from aqueous medium

A low-cost biosorbent obtained from the Palomino Fino grape seed, a Sherry wine industry by-product, has been proposed as a way of valorising this material. The biomass was characterised obtaining values of 0.68 +/- 0.05 g mL(-1) for bulk density, 1.02 +/- 0.09 g mL(-1) for apparent density and 33.3% for porosity. The pH(pzc) was 5.2 and the surface negative charge value was 2.4 +/- 0.2 mmol g(-1). The analysis of surface morphology showed differences due to the sorption. The results showed a promising potential for chromium(VI) removal from aqueous solutions. The studies were carried out in batch scale and a 2(3) factorial design was applied for the optimisation of the process. A percentage of 91.7 +/- 0.6% was achieved for the biosorption of Cr(VI) under optimal conditions using pH 5.5, 15 g/L of biosorbent and 8 h of contact time. The biosorption capacity showed a remarkable linearity from 0 to 2 mmol L-1 Cr(VI) and a precision of 0.64% for the removal of 1 mmol L-1 of metal. Langmuir, Freundlich and Temkin isotherm equations and the parameters of six kinetic models were used in the equilibrium modelling and identifying the mechanism of the biosorption. The combination of physical and chemical sorption mechanisms was proposed for the chromium removal with a high maximum sorption capacity (q(max) = 208.3 mg g(-1)). Thermodynamic parameters indicated the spontaneous and endothermic nature of the chromium removal. The successful biosorption was based on the special grape seed components with a relevant content in antioxidant and lignocellulosic compounds.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

Sensing Cd(II) Using a Disposable Optical Sensor Based on a Schiff Base Immobilisation on a Polymer-Inclusion Membrane. Applications in Water and Art Paint Samples

A disposable colour-changeable optical sensor based on an interesting polymer inclusion-membrane (PIM) was designed to determine Cd(II) ions in aqueous medium. The Schiff base 2-acetylpyridine benzoylhydrazone (2-APBH) immobilised on the polymer membrane was used as a sensing molecule. The amounts of the PIM components were optimised by a 3(2) fractional factorial design with two central points and two blocks. The best optical sensor composition consisted of 2.5 g of poly(vinylchloride) (PVC) as a base polymer, 3 mL of tributyl phosphate (TBP) as a plasticiser, and 0.02 g of 2-APBH as a reagent. The sensor showed a good linear response in the range from 0.02 mg L-1 (limit of detection) to 1 mg L-1 of Cd(II) under the following experimental conditions: pH 9.5 (adjusted using ammonium chloride buffer solution at 0.337 mol L-1), 60 min of exposure time plus 2 min of sonication (pulses at 2 s intervals), and 10 min of short-term stability. The relative standard deviation of the method was determined to be 4.04% for 0.4 mg L-1 of Cd(II). The optical sensor was successfully applied to the determination of Cd(II) in natural-water and art-paint samples

Opinions on the Orchard of the Lower Segura River: A Changing Space under Great Human Pressure

What makes the Lower Segura River (southeast of Spain) unique is the existence of a densely populated and entropized territory around a smallholder agricultural activity that for centuries has shaped the so-called “Segura Orchard.” In recent years, there has been widespread occupation due to the construction of secondary residences, which has clearly changed the rural appearance, sometimes creating an image more typical of disorderly residential urbanization than of an inhabited agricultural territory. The objective of this paper is to determine the attitude and position of the resident population regarding the situation and future prospects that are envisioned for this area. In this paper, we have conducted a personal and open interview as a technique to collect the information. If we are not capable of generating sustainable socio-economic activity, we will not be able to preserve, protect and transcend what we still know as an orchard. This spatial structure is undoubtedly singular and complex, and after a process of loss of identity and alteration of traditional uses, it requires an intervention that tends to organize it and protect the important territorial heritage that it still preserves.This research was funded by the Fondo Nacional de Desarrollo Científico y Tecnológico (FONDECYT 11161097) granted by the Government of Chile.
