Competitiveness and Sustainability in tourist firms and destinations
2020
Tourism is a major activity in the global economy, not only in terms of its economic impact but also its social and environmental implications. The management practices and processes adopted by tourist companies and destinations are very heterogeneous and have variable impacts on the triple-bottom-line sustainability (people, profit, planet) of the ecosystem. However, there is still only limited available knowledge about the value of different practices for promoting both sustainable development and greater competitiveness. This Special Issue includes papers that present new ideas, theories, advancements, experiences, evidence or methodologies that support the convergence of economic, socia…
Energy and environmental assessment of retrofit actions on a residential building
2014
Energy and environmental performances of buildings strictly depend on many factors related to the choice of construction materials, technical equipment, installation and use. In the following chapter a set of retrofit actions to improve the thermal performance of an existing conventional building is presented. The energy and environmental assessment of these actions is carried out following a life cycle approach. The embodied energy and the environmental impacts arisen from the production, transportation and installation phases of the required materials and components are calculated. Further, energy saving and environmental benefits and drawbacks concerning the assessed retrofit actions are…
Comparative environmental analysis of soil sampling methods in precision agriculture for lime application in Paraná State, Brazil
2020
Precision agriculture (PA) provides techniques that favour the localized application of inputs allowing their rational use. This makes the PA a potential indicator of reduced operational costs, input volume, and environmental impacts. The objective of this study was to evaluate and compare the environmental effects of three different sampling methods used in PA for the lime application. The first sampling method evaluated was the grid sampling (GS). It was performed at a density of one sample per hectare in a 100×100 m georeferenced grid. The second method was the directed sampling, that was performed after defining the management zones by soil apparent electrical conductivity (ECa) using a…
On the use of unmanned aerial systems for environmental monitoring
2018
[EN] Environmental monitoring plays a central role in diagnosing climate and management impacts on natural and agricultural systems; enhancing the understanding of hydrological processes; optimizing the allocation and distribution of water resources; and assessing, forecasting, and even preventing natural disasters. Nowadays, most monitoring and data collection systems are based upon a combination of ground-based measurements, manned airborne sensors, and satellite observations. These data are utilized in describing both small-and large-scale processes, but have spatiotemporal constraints inherent to each respective collection system. Bridging the unique spatial and temporal divides that li…
Regional economic structures in Finland : analyses of location and regional economic impact
2007
This dissertation consists of nine empirical studies which seek to broaden understanding of Finnish regional economic structures. These studies are divided between two topics: 1) regional specialization and industrial concentration in Finland, and 2) regional economic impact analysis. The empirical studies are preceded by an introduction, in which the theoretical background, outline and the main results of the thesis are presented. The research on the first topic is guided by the new economic geography literature, from which answers are sought to the location and agglomeration questions addressed in this dissertation. Evidence is found of increasing post-recession specialization in Finland.…
La larga huella en el territorio de las viviendas secundarias ilegales. El ejemplo de Gilet (Valencia)
2019
Los grupos de viviendas secundarias ilegales desarrolladas en España en el entorno de las principales áreas urbanas entre 1960 y 1985 han dejado una profunda huella negativa en el territorio que perdura casi medio siglo después y que en algunos aspectos resulta de muy difícil solución. Las principales consecuencias son desorden territorial, importantes impactos ambientales y paisajísticos, carencia o mala calidad de infraestructuras, equipamientos y servicios públicos que acaban siendo una carga económica para la comunidad e incluso generando conflictos políticos que han complicado la gobernanza local. A partir del estudio del municipio de Gilet (Valencia), un ejemplo paradigmático de este …
What makes a citrus farmer go 'organic'? Empirical evidence from Spanish citrus farming
2012
Organic farming is increasing its share of total world food output and receiving grow-ing support from policymakers concerned with agricultural sustainability issues. This paper studies the characteristics of citrus farmers in the Spanish region of Valencia that affect their probability of becoming organic farmers. A fair understanding of these characteristics may help policymakers improve the design of agricultural policies aimed at supporting organic citrus practices. As regards the methodology, a probit model is estimated with information from a sample of conventional and organic citrus farmers obtained from a survey designed for a larger research project aimed at analysing Valencian cit…
Evaluación de políticas y dación de cuentas, requisitos para una adecuada gobernabilidad territorial a partir de una nueva planificación; combinando …
2014
Una adecuada gobernabilidad del territorio es un factor clave para lograr un desarrollo justo, democrático y en dignidad. Para ello se consideran elementos decisivos la reinterpretación de la labor de gobierno, con renovadas prácticas de gobernanza más democrática y participada, la incorporación del territorio en la agenda política y la recuperación del espacio de vida en aplicación y desarrollo del principio de subsidiariedad. Muchas de estas cuestiones forman parte del acervo común y representan un potencial y atractivo campo de desarrollo profesional de la geografía. El texto analiza las relaciones entre gobierno, gobernanza y gobernabilidad, tendiendo puentes entre geografía y política,…
Quality of environmental impact assessment in Finland
2014
2017
Abstract. Remote sensing of the gaseous composition of non-eruptive, passively degassing volcanic plumes can be a tool to gain insight into volcano interior processes. Here, we report on a field study in September 2015 that demonstrates the feasibility of remotely measuring the volcanic enhancements of carbon dioxide (CO2), hydrogen fluoride (HF), hydrogen chloride (HCl), sulfur dioxide (SO2), and bromine monoxide (BrO) in the downwind plume of Mt. Etna using portable and rugged spectroscopic instrumentation. To this end, we operated the Fourier transform spectrometer EM27/SUN for the shortwave-infrared (SWIR) spectral range together with a co-mounted UV spectrometer on a mobile platform in…
