A hydrological–economic model for sustainable groundwater use in sparse-data drylands: Application to the Amtoudi Oasis in southern Morocco, northern Sahara

A hydrological–economic model is introduced to describe the dynamics of groundwater-dependent economics (agriculture and tourism) for sustainable use in sparse-data drylands. The Amtoudi Oasis, a remote area in southern Morocco, in the northern Sahara attractive for tourism and with evidence of groundwater degradation, was chosen to show the model operation. Governing system variables were identified and put into action through System Dynamics (SD) modeling causal diagrams to program basic formulations into a model having two modules coupled by the nexus ‘pumping’: (1) the hydrological module represents the net groundwater balance (G) dynamics; and (2) the economic module reproduces the variation in the consumers of water, both the population and tourists. The model was operated under similar influx of tourists and different scenarios of water availability, such as the wet 2009–2010 and the average 2010–2011 hydrological years. The rise in international tourism is identified as the main driving force reducing emigration and introducing new social habits in the population, in particular concerning water consumption. Urban water allotment (PU) was doubled for less than a 100-inhabitant net increase in recent decades. The water allocation for agriculture (PI), the largest consumer of water, had remained constant for decades. Despite that the 2-year monitoring period is not long enough to draw long-term conclusions, groundwater imbalance was reflected by net aquifer recharge (R) less than PI + PU (G < 0) in the average year 2010–2011, with net lateral inflow from adjacent Cambrian formations being the largest recharge component. R is expected to be much less than PI + PU in recurrent dry spells. Some low-technology actions are tentatively proposed to mitigate groundwater degradation, such as: wastewater capture, treatment, and reuse for irrigation; storm-water harvesting for irrigation; and active maintenance of the irrigation system to improve its efficiency.

Geological risk assessment of Amtoudi Agadir in southern Morocco: a key case for sustainable cultural heritage

Medieval fortified granaries known as “agadirs” are very common in southern Morocco, being catalogued as world cultural heritage by United Nations. These Berber buildings (made of stones and tree trunks) usually located on rocky promontories, constitute historical testimonials related to the origin of Morocco, and, as tourist attractions, have a positive impact on the local economy. The sustainability of these ancient monuments requires geological-risk evaluations of the massif stability under the agadir with the proposal of stabilization measures, and an architectonic analysis with appropriate maintenance of the structural elements. An interdisciplinary study including climate, seismicity, hydrology, geology, geomorphology, geotechnical surveys of the massif, and diagnosis of the degradation of structural elements have been performed on the Amtoudi Agadir, selected as a case study. The main findings from this study are that the prevalent rocks used for construction (coming from the underlying substratum) are good-quality arkosic sandstones; the SW cliffs under the agadir are unstable under water saturation; some masonry walls are too thin and lack interlocking stones and mortar; and failures in the beams (due to flexure, fracture, and exhaustion in the resistance due to insect attacks or plant roots) are common. The basic risk assessment of ancient buildings of cultural heritage and their geologic substratum are needed especially in undeveloped areas with limited capacity to implement durable conservation policies. Therefore, recommendations have been provided to ensure the stability and maintenance of this important archaeological site.

Antonio Maura y el papel del II Reich en las negociaciones hispano-francesas sobre Marruecos de 1903-1904

En la primera parte del artículo se aborda el problema que ha de afrontar el estadista Antonio Maura al convertirse en el jefe del gobierno español, a finales de 1903 y consistente en concluir el proceso de negociación sobre Marruecos entablado con Francia desde 1901. Se resalta el carácter continuista del ideario colonial de Maura con respecto al del anterior líder conservador, Silvela, y la preponderancia de cuestiones como la seguridad nacional como motivadoras de dicho ideario. En la segunda parte, se explica la apelación del gobierno maurista a una ayuda por parte de Alemania, en función de movimientos previos de la diplomacia germana que se había interesado por controlar una parte del Marruecos español, o por conseguir compensaciones en Fernando Po. Finalmente se analiza el intento de Berlín de instrumentalizar al gobierno Maura en el curso de las conversaciones hispano-francesas sobre el Imperio jerifiano.

Application of the Putting Women First protocol in a study on violence against immigrant women in Spain

In this paper, we describe our experience of using the Putting Women First protocol in the design and implementation of a cross-sectional study on violence against women (VAW) among 1607 immigrant women from Morocco, Ecuador and Romania living in Spain in 2011. The Putting Women First protocol is an ethical guideline for VAW research, which includes recommendations to ensure the safety of the women involved in studies on this subject. The response rate in this study was 59.3%. The prevalence of VAW cases last year was 11.7%, of which 15.6% corresponded to Ecuadorian women, 10.9% to Moroccan women and 8.6% to Romanian women. We consider that the most important goal for future research is the use of VAW scales validated in different languages, which would help to overcome the language barriers encountered in this study.

Percepción de las trabajadoras inmigrantes del servicio doméstico sobre los efectos de la regulación del sector en España

Objetivo: Explorar las percepciones de las mujeres inmigrantes trabajadoras del servicio doméstico sobre la puesta en vigor en España del Real Decreto 1620/2011, que regula la relación laboral del servicio del hogar familiar, y su efecto en sus condiciones de empleo. Métodos: Estudio exploratorio mediante análisis de contenido cualitativo. Se realizaron tres grupos de discusión con mujeres inmigrantes (colombianas, ecuatorianas y marroquíes). Resultados: A pesar de valorar positivamente los beneficios teóricos de la nueva normativa, las mujeres inmigrantes han identificado barreras legales y económicas para conseguir un contrato, ser dadas de alta en la seguridad social y que las personas empleadoras asuman su coste, en especial en el caso de las trabajadoras contratadas por horas. Estas dificultades influyen en la posibilidad de legalizar su situación. La confluencia con la crisis económica ha emergido como un problema que dificulta su cumplimiento. Conclusiones: Aunque el nuevo régimen ha favorecido la creación de puestos de trabajo con mayores derechos laborales en el sector, las mujeres inmigrantes perciben que su puesta en marcha en el actual contexto de crisis económica no ha contribuido a mejorar sus condiciones de empleo.

Understanding sickness presenteeism through the experience of immigrant workers in a context of economic crisis

Background: Previous economic recessions show that immigrant workers may experience longer periods of unemployment, a situation that may lead employees to presenteeism, the act of working in spite of a health problem. This study explored perceptions about the factors that lead to presenteeism in immigrant workers considering the context of economic crisis. Methods: Six focus group discussions were held (February 2012), with men and women from Colombia, Ecuador, and Morocco (n = 44) living in Spain and selected by theoretical sample. A qualitative content analysis was performed. Results: Four categories were identified as factors that influence the occurrence of presenteeism in a context of economic crisis: poor employment conditions, fear of unemployment, employer/employee relationship, and difficulties in finding temporary replacement workers. Furthermore, musculoskeletal, respiratory, and mental problems were related to presenteeism. Conclusions: It is important to develop strategies to protect workers from negative working conditions that are associated with deterioration of health.

From the boom to the crisis: changes in employment conditions of immigrants in Spain and their effects on mental health

Background: Migrant workers have been one of the groups most affected by the economic crisis. This study evaluates the influence of changes in employment conditions on the incidence of poor mental health of immigrant workers in Spain, after a period of 3 years, in context of economic crisis. Methods: Follow-up survey was conducted at two time points, 2008 and 2011, with a reference population of 318 workers from Colombia, Ecuador, Morocco and Romania residing in Spain. Individuals from this population who reported good mental health in the 2008 survey (n = 214) were interviewed again in 2011 to evaluate their mental health status and the effects of their different employment situations since 2008 by calculating crude and adjusted odds ratios (aORs) for sociodemographic and employment characteristics. Findings: There was an increased risk of poor mental health in workers who lost their jobs (aOR = 3.62, 95%CI: 1.64–7.96), whose number of working hours increased (aOR = 2.35, 95%CI: 1.02–5.44), whose monthly income decreased (aOR = 2.75, 95%CI: 1.08–7.00) or who remained within the low-income bracket. This was also the case for people whose legal status (permission for working and residing in Spain) was temporary or permanent compared with those with Spanish nationality (aOR = 3.32, 95%CI: 1.15–9.58) or illegal (aOR = 17.34, 95%CI: 1.96–153.23). In contrast, a decreased risk was observed among those who attained their registration under Spanish Social Security system (aOR = 0.10, 95%CI: 0.02–0.48). Conclusion: There was an increase in poor mental health among immigrant workers who experienced deterioration in their employment conditions, probably influenced by the economic crisis.

A qualitative exploration of the impact of the economic recession in Spain on working, living and health conditions: reflections based on immigrant workers' experiences

Background: This study aimed to analyse how immigrant workers in Spain experienced changes in their working and employment conditions brought about Spain's economic recession and the impact of these changes on their living conditions and health status. Method: We conducted a grounded theory study. Data were obtained through six focus group discussions with immigrant workers (n = 44) from Colombia, Ecuador and Morocco, and two individual interviews with key informants from Romania living in Spain, selected by theoretical sample. Results: Three categories related to the crisis emerged – previous labour experiences, employment consequences and individual consequences – that show how immigrant workers in Spain (i) understand the change in employment and working conditions conditioned by their experiences in the period prior to the crisis, and (ii) experienced the deterioration in their quality of life and health as consequences of the worsening of employment and working conditions during times of economic recession. Conclusion: The negative impact of the financial crisis on immigrant workers may increase their social vulnerability, potentially leading to the failure of their migratory project and a return to their home countries. Policy makers should take measures to minimize the negative impact of economic crisis on the occupational health of migrant workers in order to strengthen social protection and promote health and well-being.
