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…
The fumarolic CO2 output from Pico do Fogo volcano (Cape Verde)
2020
The Pico do Fogo volcano, in the Cape Verde Archipelago off the western coasts of Africa, has been the most active volcano in the Macaronesia region in the Central Atlantic, with at least 27 eruptions during the last 500 years. Between eruptions fumarolic activity has been persisting in its summit crater, but limited information exists for the chemistry and output of these gas emissions. Here, we use the results acquired during a field survey in February 2019 to quantify the quiescent summit fumaroles' volatile output for the first time. By combining measurements of the fumarole compositions (using both a portable Multi-GAS and direct sampling of the hottest fumarole) and of the SO2 flux (u…

Spatially resolved SO2 flux emissions from Mt Etna
2016
We report on a systematic record of SO2 flux emissions from individual vents of Etna volcano (Sicily), which we obtained using a permanent UV camera network. Observations were carried out in summer 2014, a period encompassing two eruptive episodes of the New South East Crater (NSEC) and a fissure-fed eruption in the upper Valle del Bove. We demonstrate that our vent-resolved SO2 flux time series allow capturing shifts in activity from one vent to another and contribute to our understanding of Etna's shallow plumbing system structure. We find that the fissure eruption contributed ~50,000 t of SO2 or ~30% of the SO2 emitted by the volcano during the 5 July to 10 August eruptive interval. Acti…
Hydrothermal buffering of the SO2/H2S ratio in volcanic gases: Evidence from La Fossa Crater fumarolic field, Vulcano Island
2006
[1] Sulfur speciation in volcanic gases is a potentially valuable tracer of degassing processes at volcanoes. Hitherto, observations of sulfur speciation in volcanic gas plumes have however been limited both in number and quality. Here, we report on periodic measurements of SO2 to H2S proportions in the volcanic gases from La Fossa volcano (Vulcano Island) performed during 2004–2006, a period which encompasses two heating events of the fumarolic field in January–April 2005 and December 2005. Results indicate a systematic relative increase (by a factor of 2–6) of SO2 to H2S proportions in the fumaroles during the heating events, which we ascribe to a temperature increase in the mixing zone b…
