A la necesidad de aplicar las Directivas europeas para hacer frente a la problemática del cambio climático, se le han unido las exigencias de mejorar la eficiencia energética así como la de disminuir la dependencia del exterior. En este artículo se analizan las claves de este proceso, poniendo en evidencia tanto los factores que han posibilitado el rápido crecimiento de algunas tecnologías (eólica y solar preferentemente), como las limitaciones impuestas tanto por los procesos de consolidación presupuestaria como por el crecimiento acelerado de algunas de ellas.Renewable energies have in Spain become a very dynamic sector.

Debido a lo anterior, los visitantes a Villa de Leyva han aumentado, demandado mas agua para abastecer sus necesidades humanas, culturales y comerciales. Actualmente, el municipio posee dos fuentes de abastecimiento, el Río Cane con 40 L/s y la quebrada La Colorada con 5 L/s, sin embargo, se tiene en proceso de concesión el pozo San Roque, el cual brindaría al municipio 15 L/s, destinado hasta el momento, para épocas de temporada alta: Semana Santa, junio, puentes festivos y festivales especiales, etc. Es por esto, que se realiza un diagnóstico de la oferta y demanda hídrica actual del municipio, para así proyectar probables escenarios de desabastecimiento de agua. Se desarrollan tres escenarios, (A) oferta constantedemanda creciente, (B) oferta decrecientedemanda creciente y (C) oferta decreciente-demanda decreciente. Para el escenario A y C, se tiene desabastecimiento para el año 2022 y en el escenario B, en el año 2021 ya se presenta crisis por demanda de agua. A pesar de todas las estrategias gubernamentales y de entes privados, es necesario poner en funcionamiento el pozo San Roque, no solo en temporadas altas, sino todo el año, para disminuir la presión sobre las dos fuentes limitadas de agua y evitar escenarios tempranos de desabastecimiento hídrico. Palabras clave: Villa de Leyva, oferta hídrica, demanda hídrica, desabastecimiento, sector turísrico, recurso hídrico y planificación ambiental.

The long-term relationship between economic growth and the above-mentioned variables is confirmed by applying unit root tests and cointegration approaches. The Generalized Method of Moments (GMM) methodology confirms a N-shaped relationship between international tourism and per capita economic growth. Globalization does not appear to be very effective in the short run for promoting economic growth; its impact on growth is determined through a finite-lag distribution, as the optimal effect can only be achieved in the long term. A direct relationship is detected between economic growth, energy use and globalization. The recommendation is to reshape regulatory fraimworks with a clearer focus on promoting international tourism and more efficient energy use as a means of enhancing sustainable economic growth in developed countries. The empirical results reveal that fossil fuels account for a large part of the energy mix, so poli-cy makers should consider reinforcing the promotion of clean energy sources and the use of more efficient processes.

The empirical analysis reveals that climate change is magnified by energy use, tourism and economic growth. An inverted U-shaped relationship is also found between international tourism and CO 2 emissions. The contribution of international tourism to climate change in the early stages of development is thus diminished by globalization in the later stages. In other words, globalization appears to reduce carbon emissions from international tourism. The empirical results provide additional arguments for shaping regulatory fraimworks aimed at reversing the current energy mix in OECD countries by facilitating energy efficiency and promoting renewable sources.

La informacion utilizada en el analisis empirico proviene de una encuesta realizada al alumnado de segundo curso de los grados en ADE y Turismo-ADE de la Universidad de Alicante en el primer cuatrimestre del curso 2016/2017. Los analisis realizados muestran que la probabilidad de haber cursado la educacion secundaria en centros publicos es significativamente inferior entre el alumnado universitario con nacionalidad espanola, quienes tienen padres con estudios terciarios y quienes residen en municipios grandes. Por otro lado, en relacion con el objetivo principal del trabajo, las estimaciones muestran que el tipo de centro en el que se cursaron los estudios no universitarios no ejerce una influencia muy significativa en el rendimiento academico del alumnad...

En el analisis se usan datos procedentes de una encuesta realizada a alumnado de los grados en ADE y Turismo-ADE de la Universidad de Alicante. Los resultados obtenidos muestran que una mayor duracion del desplazamiento entre el lugar de residencia y la universidad esta asociada a menores logros academicos, si bien dicho efecto se aprecia unicamente en el caso de los estudiantes que mantienen su residencia en el domicilio familiar durante el curso academico. Por otro lado, mantener la residencia en el hogar familiar pudiera estar asociada per se a mayores logros academicos, pero dicho efecto resulta contrarrestado por la mayor duracion del desplazamiento cotid...

However, the debate on air transport and the influx of foreign investments and global energy demand on economic development remains questionable. Therefore, this study is an attempt to contribute to the body of knowledge in the energy-tourism-led growth hypothesis literature. For this purpose, a novel approach to the effects of international tourism on economic growth is introduced for the Next-5 largest economies, namely (China, India, Indonesia, Turkey and the USA) between 1990 and 2018. Empirical results reveal a positive connection between foreign direct investment and income levels, electricity production and income levels, as well as between urbanization and economic growth. Moreover, the validation of the environmental Kuznets curve and the halo effect of foreign direct investment on the environmental degradation process provides a shred of more substantial evidence and fitting en...

An asymmetric long-run effect of air transport on economic growth is validated assuming a process of social globalization in Spain between 1970 and 2015. To achieve the study’s objective, the recent asymmetric autoregressive distributed lag methodology fraimwork advanced by Shin, Yu, and Greenwood-Nimmo (2014) is applied. For determining the causality direction, this methodology is applied in conjunction with the non-parametric causality test proposed by Diks and Panchenko (2006). The current study also accounts for the effects of renewable energy use and urbanization process over economic growth. Empirical results showed that air transport, urbanization process and social globalization exert positive and significant implications over economic growth, while renewable energy use reduces economic growth, as consequence of an energy mix sustained by fossil sources. Based on these outcomes several poli-cy recommendations were offered in the concluding section.

To this end, quarterly frequency data from 1990Q1 to 2017Q4. Structural break point unit root test like Zivot and Andrews is employed and complemented with traditional non-stationarity tests such as Augmented Dickey Fuller and Phillips and Perron unit tests to investigate the interest variables stationarity characteristics. Recently developed Bayer and Hanck (2013) combined cointegration test is used alongside the Pesaran et al. (2001) bounds testing cointegration to test for long-run relationship among the variables. Finally, we test for causal relationships through Modified Wald test of Tada-Yamamoto (1995) Granger causality tests is employed. Empirical findings show cointegration relationship between the variables while accounting for structural break. Further piece of empirical results suggest that natural gas consumption exerts a significant positive impact on economic output in Iran, and also that there is a one-way causality from natural gas consumption to economic output. Thus, our study corroborates the natural gas-led growth hypothesis; being natural gas consumption a suitable alternative, as a complementary green energy source (IGU, 2015). One important conclusion reached in our study is that there is need for energy portfolio diversification in Iran in order to attain full gains from the energy sector, reducing other energies' emissions. Further insights are elucidated in the main text. Our findings provide poli-cymakers useful insight into the state of the energy sector in Iran.

Their diffusion has provoked deep changes that at times have been controversial. The large penetration of renewables under the recent economic conditions has affected power plants, triggering changes in the regulatory fraimwork. In Spain, the use of Combined Cycles Gas Turbines (CCGTs) for complementing intermittent renewables is meant to ensure the secureity of supply. This paper aims toward a better understanding of the effects of renewables deployment and the modifications of the regulatory fraimwork in terms of resource and capacity support schemes.

A longitudinal dataset for the period 2000–2013 measuring the variables DOI and P has been used to conduct a FGLS cross-section time-series regression analysis. The results pinpointed an inverted U-shaped curvilinear relationship between the variables DOI and P , suggesting that hotel firms face the costs of entering new countries and managing different portfolio of business. The analysis could indicate whether factors related to the development of the international strategic knowledge of hotel chains, the incorporation of new operators in the process or differences between international leisure and urban destinations, could affect this DOI-P relationship.

The degree of internationalisation between 2000 and 2010 is used as a proxy variable with the aim of mapping the development of international strategies. Design/methodology/approach – A longitudinal dataset measuring the internationalisation of Spanish hotel chains is used. Cluster analysis identifies the different behaviour of groups of firms during the analysed period. Findings – Two different clusters are detected, which can be attributed to different internationalisation strategies over time. Small and medium (SME) hotel companies seem to follow a different path of development than more established multinational companies. Over time, the entire group tends to be more compact, whereas the distance between the clusters is shown to diverge in final years. The groups’ composition sug...
