Modelos de análisis econométrico espacial aplicados al desarrollo económico

Los modelos de desarrollo regional, rural y urbano arrancaron en la década de los 90 en Estados Unidos, modelando los factores relacionados con la economía que suministran información y conocimiento acerca de cómo los parámetros geográficos y otros externos influencian la economía regional. El desarrollo regional y en particular el rural han seguido diferentes caminos en Europa y España, adoptando como modelo los programas estructurales de la UE ligados a la PAC. El Programa para el Desarrollo Rural Sostenible, recientemente lanzado por el Gobierno de España (2010) no profundiza en los modelos económicos de esta economía y sus causas. Este estudio pretende encontrar pautas de comportamiento de las variables de la economía regional-rural, y como el efecto de distribución geográfica de la población condiciona la actividad económica. Para este propósito, y utilizando datos espaciales y económicos de las regiones, se implementaran modelos espaciales que permitan evaluar el comportamiento económico, y verificar hipótesis de trabajo sobre la geografía y la economía del territorio. Se utilizarán modelos de análisis espacial como el análisis exploratorio espacial y los modelos econométricos de ecuaciones simultáneas, y dentro de estas los modelos ampliamente utilizados en estudios regionales de Carlino-Mills- Boarnet. ABSTRACT The regional development models for rural and urban areas started in USA in the ´90s, modeling the economy and the factors involved to understand and collect the knowledge of how the external parameters influenced the regional economy. Regional development and in particular rural development has followed different paths in Europe and Spain, adopting structural programs defined in the EU Agriculture Common Policy. The program for Sustainable Rural Development recently implemented in Spain (2010) is short sighted considering the effects of the regional economy. This study endeavors to underline models of behavior for the rural and regional economy variables, and how the regional distribution of population conditions the economic activities. For that purpose using current spatial regional economic data, this study will implement spatial economic models to evaluate the behavior of the regional economy, including the evaluation of working hypothesis about geography and economy in the territory. The approach will use data analysis models, like exploratory spatial data analysis, and spatial econometric models, and in particular for its wide acceptance in regional analysis, the Carlino-Mills-Boarnet equations model.

Improving runoff estimates from regional climate models: a performance analysis in Spain

An important step to assess water availability is to have monthly time series representative of the current situation. In this context, a simple methodology is presented for application in large-scale studies in regions where a properly calibrated hydrologic model is not available, using the output variables simulated by regional climate models (RCMs) of the European project PRUDENCE under current climate conditions (period 1961–1990). The methodology compares different interpolation methods and alternatives to generate annual times series that minimise the bias with respect to observed values. The objective is to identify the best alternative to obtain bias-corrected, monthly runoff time series from the output of RCM simulations. This study uses information from 338 basins in Spain that cover the entire mainland territory and whose observed values of natural runoff have been estimated by the distributed hydrological model SIMPA. Four interpolation methods for downscaling runoff to the basin scale from 10 RCMs are compared with emphasis on the ability of each method to reproduce the observed behaviour of this variable. The alternatives consider the use of the direct runoff of the RCMs and the mean annual runoff calculated using five functional forms of the aridity index, defined as the ratio between potential evapotranspiration and precipitation. In addition, the comparison with respect to the global runoff reference of the UNH/GRDC dataset is evaluated, as a contrast of the “best estimator” of current runoff on a large scale. Results show that the bias is minimised using the direct original interpolation method and the best alternative for bias correction of the monthly direct runoff time series of RCMs is the UNH/GRDC dataset, although the formula proposed by Schreiber (1904) also gives good results

Sustainable development in North Bohuslän (Sweden): an analysis in three scales

Partiendo del estudio de la zona que discurre por la carretera E6 en su recorrido desde el municipio de Uddevala, al suroeste de Suecia hasta la frontera con Noruega se analizan las afecciones producidas en los asentamientos y el paisaje. El proyecto se estructura en tres escalas diferentes: regional, intermedia y local para entender la fuerte conexión entre las mismas. A nivel regional se analizan los tipos de paisaje por medio de un inventario utilizando el método PEBOSCA, dentro del programa Hábitat de las Naciones Unidas estudiando todos los recursos (físicos, biológicos, sociales, económicos, organizacionales... ) de una zona determianda ; y el método DAFO (en inglés SWOT)que se ocupa de las fuerzas y debilidades de la región. Se identifican los problemas más importantes, a saber, ampliar los servicios durante todo el año, mejorar la conectividad extendiendo el transporte público y carriles para bicicletas y mejorar la calidad del agua mitigando su efecto barrera. En un nivel intermedio, el proyecto se centra en la localidad de Hogdalsnäset por estar afectado por una falta de estructura urbana y por su proximidad a la frontera con Noruega. En el plano local se analiza la zona de Nordby presentando un plan alternativo de desarrollo a corto, medio y largo plazo. Por último, la autora concluye con la propuesta de construcción del "Parque del Humedal".

Urban sprawl and city compactness. A proposal for regional sustainability indicators. Case study of the towns of Alcorcon and Majadahonda (Comunidad de Madrid, Spain)

The main contribution of this research paper is to display a range of figures and values which could help urban planners to quantify the urban phenomenon of sprawl. In this way, after a rigorous analysis and comparison between a scattered urban fabric (Majadahonda) and a compact urban fabric (Alcorcón), several possible indexes are established and characterized in order to verify the main hypothesis: in what extent land consumption and exploitation of energy resources are higher in a scattered urban fabric than in a compact one.

Flood frequency analysis by a bivariate model based on copulas

La adecuada estimación de avenidas de diseño asociadas a altos periodos de retorno es necesaria para el diseño y gestión de estructuras hidráulicas como presas. En la práctica, la estimación de estos cuantiles se realiza normalmente a través de análisis de frecuencia univariados, basados en su mayoría en el estudio de caudales punta. Sin embargo, la naturaleza de las avenidas es multivariada, siendo esencial tener en cuenta características representativas de las avenidas, tales como caudal punta, volumen y duración del hidrograma, con el fin de llevar a cabo un análisis apropiado; especialmente cuando el caudal de entrada se transforma en un caudal de salida diferente durante el proceso de laminación en un embalse o llanura de inundación. Los análisis de frecuencia de avenidas multivariados han sido tradicionalmente llevados a cabo mediante el uso de distribuciones bivariadas estándar con el fin de modelar variables correlacionadas. Sin embargo, su uso conlleva limitaciones como la necesidad de usar el mismo tipo de distribuciones marginales para todas las variables y la existencia de una relación de dependencia lineal entre ellas. Recientemente, el uso de cópulas se ha extendido en hidrología debido a sus beneficios en relación al contexto multivariado, permitiendo superar los inconvenientes de las técnicas tradicionales. Una copula es una función que representa la estructura de dependencia de las variables de estudio, y permite obtener la distribución de frecuencia multivariada de dichas variables mediante sus distribuciones marginales, sin importar el tipo de distribución marginal utilizada. La estimación de periodos de retorno multivariados, y por lo tanto, de cuantiles multivariados, también se facilita debido a la manera en la que las cópulas están formuladas. La presente tesis doctoral busca proporcionar metodologías que mejoren las técnicas tradicionales usadas por profesionales para estimar cuantiles de avenida más adecuados para el diseño y la gestión de presas, así como para la evaluación del riesgo de avenida, mediante análisis de frecuencia de avenidas bivariados basados en cópulas. Las variables consideradas para ello son el caudal punta y el volumen del hidrograma. Con el objetivo de llevar a cabo un estudio completo, la presente investigación abarca: (i) el análisis de frecuencia de avenidas local bivariado centrado en examinar y comparar los periodos de retorno teóricos basados en la probabilidad natural de ocurrencia de una avenida, con el periodo de retorno asociado al riesgo de sobrevertido de la presa bajo análisis, con el fin de proporcionar cuantiles en una estación de aforo determinada; (ii) la extensión del enfoque local al regional, proporcionando un procedimiento completo para llevar a cabo un análisis de frecuencia de avenidas regional bivariado para proporcionar cuantiles en estaciones sin aforar o para mejorar la estimación de dichos cuantiles en estaciones aforadas; (iii) el uso de cópulas para investigar tendencias bivariadas en avenidas debido al aumento de los niveles de urbanización en una cuenca; y (iv) la extensión de series de avenida observadas mediante la combinación de los beneficios de un modelo basado en cópulas y de un modelo hidrometeorológico. Accurate design flood estimates associated with high return periods are necessary to design and manage hydraulic structures such as dams. In practice, the estimate of such quantiles is usually done via univariate flood frequency analyses, mostly based on the study of peak flows. Nevertheless, the nature of floods is multivariate, being essential to consider representative flood characteristics, such as flood peak, hydrograph volume and hydrograph duration to carry out an appropriate analysis; especially when the inflow peak is transformed into a different outflow peak during the routing process in a reservoir or floodplain. Multivariate flood frequency analyses have been traditionally performed by using standard bivariate distributions to model correlated variables, yet they entail some shortcomings such as the need of using the same kind of marginal distribution for all variables and the assumption of a linear dependence relation between them. Recently, the use of copulas has been extended in hydrology because of their benefits regarding dealing with the multivariate context, as they overcome the drawbacks of the traditional approach. A copula is a function that represents the dependence structure of the studied variables, and allows obtaining the multivariate frequency distribution of them by using their marginal distributions, regardless of the kind of marginal distributions considered. The estimate of multivariate return periods, and therefore multivariate quantiles, is also facilitated by the way in which copulas are formulated. The present doctoral thesis seeks to provide methodologies that improve traditional techniques used by practitioners, in order to estimate more appropriate flood quantiles for dam design, dam management and flood risk assessment, through bivariate flood frequency analyses based on the copula approach. The flood variables considered for that goal are peak flow and hydrograph volume. In order to accomplish a complete study, the present research addresses: (i) a bivariate local flood frequency analysis focused on examining and comparing theoretical return periods based on the natural probability of occurrence of a flood, with the return period associated with the risk of dam overtopping, to estimate quantiles at a given gauged site; (ii) the extension of the local to the regional approach, supplying a complete procedure for performing a bivariate regional flood frequency analysis to either estimate quantiles at ungauged sites or improve at-site estimates at gauged sites; (iii) the use of copulas to investigate bivariate flood trends due to increasing urbanisation levels in a catchment; and (iv) the extension of observed flood series by combining the benefits of a copula-based model and a hydro-meteorological model.

Greenfield shopping center development. The integration between environmental features, building design and investment analysis at the decision making stage

The Shopping centre is a long term investment in which Greenfield development decisions are often taken based on risks analysis regarding construction costs, location, competition, market and an expected DCF. Furthermore, integration between the building design, project planning, operational costs and investment analysis is not entirely considered by the investor at the decision making stage. The absence of such information tends to produce certain negative impacts on the future running costs and annual maintenance of the building, especially on energy demand and other occupancy expenses paid by the tenants to the landlord. From the investor´s point of view, this blind spot in strategy development will possibly decrease their profit margin as changes in the occupancy expenses[ ] have a direct outcome on the profit margin. In order to try to reduce some higher operating cost components such as energy use and other utility savings as well as their CO2 emissions, quite a few income properties worldwide have some type of environmental label such as BREEAM and LEED. The drawback identified in this labelling is that usually the investments required to get an ecolabel are high and the investor finds no direct evidence that it increases market value. However there is research on certified commercial properties (especially offices) that shows better performance in terms of occupancy rate and rental cost (Warren-Myers, 2012). Additionally, Sayce (2013) says that the certification only provides a quick reference point i.e. the lack of a certificate does not indicate that a building is not sustainable or efficient. Based on the issues described above, this research compares important components of the development stages such as investments costs, concept/ strategy development as well as the current investor income and property value. The subjects for this analysis are a shopping centre designed with passive cooling/bioclimatic strategies evaluated at the decision making stage, a certified regional shopping centre and a non-certified standard regional shopping centre. Moreover, the proposal intends to provide decision makers with some tools for linking green design features to the investment analysis in order to optimize the decision making process when looking into cost savings and design quality.

Analysis of Contributions to NO2 Ambient Air Quality Levels in Madrid City (Spain) through Modeling. Implications for the Development of Policies and Air Quality Monitoring

As environmental standards become more stringent (e.g. European Directive 2008/50/EC), more reliable and sophisticated modeling tools are needed to simulate measures and plans that may effectively tackle air quality exceedances, common in large cities across Europe, particularly for NO2. Modeling air quality in urban areas is rather complex since observed concentration values are a consequence of the interaction of multiple sources and processes that involve a wide range of spatial and temporal scales. Besides a consistent and robust multi-scale modeling system, comprehensive and flexible emission inventories are needed. This paper discusses the application of the WRF-SMOKE-CMAQ system to the Madrid city (Spain) to assess the contribution of the main emitting sectors in the region. A detailed emission inventory was compiled for this purpose. This inventory relies on bottom-up methods for the most important sources. It is coupled with the regional traffic model and it makes use of an extensive database of industrial, commercial and residential combustion plants. Less relevant sources are downscaled from national or regional inventories. This paper reports the methodology and main results of the source apportionment study performed to understand the origin of pollution (main sectors and geographical areas) and define clear targets for the abatement strategy. Finally the structure of the air quality monitoring is analyzed and discussed to identify options to improve the monitoring strategy not only in the Madrid city but the whole metropolitan area.

A multi-level analysis of innovation diffusion: The case of solar photovoltaic systems in Germany and the disillusion of grid parity

¿Suministrarán las fuentes de energía renovables toda la energía que el mundo necesita algún día? Algunos argumentan que sí, mientras que otros dicen que no. Sin embargo, en algunas regiones del mundo, la producción de electricidad a través de fuentes de energía renovables ya está en una etapa prometedora de desarrollo en la que su costo de generación de electricidad compite con fuentes de electricidad convencionales, como por ejemplo la paridad de red. Este logro ha sido respaldado por el aumento de la eficiencia de la tecnología, la reducción de los costos de producción y, sobre todo, los años de intervenciones políticas de apoyo financiero. La difusión de los sistemas solares fotovoltaicos (PV) en Alemania es un ejemplo relevante. Alemania no sólo es el país líder en términos de capacidad instalada de sistemas fotovoltaicos (PV) en todo el mundo, sino también uno de los países pioneros donde la paridad de red se ha logrado recientemente. No obstante, podría haber una nube en el horizonte. La tasa de difusión ha comenzado a declinar en muchas regiones. Además, las empresas solares locales – que se sabe son importantes impulsores de la difusión – han comenzado a enfrentar dificultades para manejar sus negocios. Estos acontecimientos plantean algunas preguntas importantes: ¿Es ésta una disminución temporal en la difusión? ¿Los adoptantes continuarán instalando sistemas fotovoltaicos? ¿Qué pasa con los modelos de negocio de las empresas solares locales? Con base en el caso de los sistemas fotovoltaicos en Alemania a través de un análisis multinivel y dos revisiones literarias complementarias, esta tesis doctoral extiende el debate proporcionando riqueza múltiple de datos empíricos en un conocimiento de contexto limitado. El primer análisis se basa en la perspectiva del adoptante, que explora el nivel "micro" y el proceso social que subyace a la adopción de los sistemas fotovoltaicos. El segundo análisis es una perspectiva a nivel de empresa, que explora los modelos de negocio de las empresas y sus roles impulsores en la difusión de los sistemas fotovoltaicos. El tercero análisis es una perspectiva regional, la cual explora el nivel "meso", el proceso social que subyace a la adopción de sistemas fotovoltaicos y sus técnicas de modelado. Los resultados incluyen implicaciones tanto para académicos como políticos, no sólo sobre las innovaciones en energía renovable relativas a la paridad de red, sino también, de manera inductiva, sobre las innovaciones ambientales impulsadas por las políticas que logren la competitividad de costes. ABSTRACT Will renewable energy sources supply all of the world energy needs one day? Some argue yes, while others say no. However, in some regions of the world, the electricity production through renewable energy sources is already at a promising stage of development at which their electricity generation costs compete with conventional electricity sources’, i.e., grid parity. This achievement has been underpinned by the increase of technology efficiency, reduction of production costs and, above all, years of policy interventions of providing financial support. The diffusion of solar photovoltaic (PV) systems in Germany is an important frontrunner case in point. Germany is not only the top country in terms of installed PV systems’ capacity worldwide but also one of the pioneer countries where the grid parity has recently been achieved. However, there might be a cloud on the horizon. The diffusion rate has started to decline in many regions. In addition, local solar firms – which are known to be important drivers of diffusion – have started to face difficulties to run their businesses. These developments raise some important questions: Is this a temporary decline on diffusion? Will adopters continue to install PV systems? What about the business models of the local solar firms? Based on the case of PV systems in Germany through a multi-level analysis and two complementary literature reviews, this PhD Dissertation extends the debate by providing multiple wealth of empirical details in a context-limited knowledge. The first analysis is based on the adopter perspective, which explores the “micro” level and the social process underlying the adoption of PV systems. The second one is a firm-level perspective, which explores the business models of firms and their driving roles in diffusion of PV systems. The third one is a regional perspective, which explores the “meso” level, i.e., the social process underlying the adoption of PV systems and its modeling techniques. The results include implications for both scholars and policymakers, not only about renewable energy innovations at grid parity, but also in an inductive manner, about policy-driven environmental innovations that achieve the cost competiveness.

Diseño de un sistema regional de alerta de tsunamis como parte integral de la operación portuaria

En este trabajo se presenta el desarrollo de una metodología para obtener un universo de funciones de Green y el algoritmo correspondiente, para estimar la altura de tsunamis a lo largo de la costa occidental de México en función del momento sísmico y de la extensión del área de ruptura de sismos interplaca localizados entre la costa y la Trinchera Mesoamericana. Tomando como caso de estudio el sismo ocurrido el 9 de octubre de 1995 en la costa de Jalisco-Colima, se estudiaron los efectos del tsunami originados en la hidrodinámica del Puerto de Manzanillo, México, con una propuesta metodológica que contempló lo siguiente: El primer paso de la metodología contempló la aplicación del método inverso de tsunamis para acotar los parámetros de la fuente sísmica mediante la confección de un universo de funciones de Green para la costa occidental de México. Tanto el momento sísmico como la localización y extensión del área de ruptura de sismos se prescribe en segmentos de planos de falla de 30 X 30 km. A cada uno de estos segmentos del plano de falla corresponde un conjunto de funciones de Green ubicadas en la isobata de 100 m, para 172 localidades a lo largo de la costa, separadas en promedio 12 km entre una y otra. El segundo paso de la metodología contempló el estudio de la hidrodinámica (velocidades de las corrientes y niveles del mar en el interior del puerto y el estudio del runup en la playa) originada por el tsunami, la cual se estudió en un modelo hidráulico de fondo fijo y en un modelo numérico, representando un tsunami sintético en la profundidad de 34 m como condición inicial, el cual se propagó a la costa con una señal de onda solitaria. Como resultado de la hidrodinámica del puerto de Manzanillo, se realizó un análisis de riesgo para la definición de las condiciones operativas del puerto en términos de las velocidades en el interior del mismo, y partiendo de las condiciones iniciales del terremoto de 1995, se definieron las condiciones límites de operación de los barcos en el interior y exterior del puerto. In this work is presented the development of a methodology in order to obtain a universe of Green's functions and the corresponding algorithm in order to estimate the tsunami wave height along the west coast of Mexico, in terms of seismic moment and the extent of the area of the rupture, in the interplate earthquakes located between the coast and the Middle America Trench. Taking as a case of study the earthquake occurred on October 9, 1995 on the coast of Jalisco-Colima, were studied the hydrodynamics effects of the tsunami caused in the Port of Manzanillo, Mexico, with a methodology that contemplated the following The first step of the methodology contemplated the implementation of the tsunami inverse method to narrow the parameters of the seismic source through the creation of a universe of Green's functions for the west coast of Mexico. Both the seismic moment as the location and extent of earthquake rupture area prescribed in segments fault planes of 30 X 30 km. Each of these segments of the fault plane corresponds a set of Green's functions located in the 100 m isobath, to 172 locations along the coast, separated on average 12 km from each other. The second step of the methodology contemplated the study of the hydrodynamics (speed and directions of currents and sea levels within the port and the study of the runup on the beach Las Brisas) caused by the tsunami, which was studied in a hydraulic model of fix bed and in a numerical model, representing a synthetic tsunami in the depth of 34 m as an initial condition which spread to the coast with a solitary wave signal. As a result of the hydrodynamics of the port of Manzanillo, a risk analysis to define the operating conditions of the port in terms of the velocities in the inner and outside of the port was made, taken in account the initial conditions of the earthquake and tsunami ocurred in Manzanillo port in 1995, were defined the limits conditions of operation of the ships inside and outside the port.

A governação de territórios metropolitanos. Contexto institucional e de planeamento nas regiões de Madrid, Barcelona, Paris e Lisboa / The regional metropolitan governance. Institutional mark and planning in Madrid, Barcelona, Paris and Lisbon

Resumo Em resposta aos desafios atuais de muitas grandes cidades, o contexto institucional e o planeamento territorial formam dimensões para melhorar a governação metropolitana. No quadro das regiões capitais do sudoeste europeu, quais poderão ser as inovações e diferenças nos seus modelos e processos em curso? Este artigo propõe uma investigação aplicada para apresentar a análise da governação metropolitana. Através do método de estudos de caso em perspectiva comparada, vários elementos e entrevistas são ponderados qualitativamente nas regiões de Madrid, Barcelona, Paris e Lisboa. As conclusões encontram uma tendência para o equilíbrio entre os esforços dessas duas dimensões da governação territorial metropolitana, não impedindo registrar os seus diferentes percursos: por exemplo Ile-de-France desenvolveu boas iniciativas em matéria de planeamento, que então pedem alguns ajustamentos no quadro político, enquanto Madrid teve “menos actividade” nos últimos anos, em resultado da sua grande estabilidade institucional. A região de Lisboa permanece talvez numa “posição intermédia”, com uma dinâmica de evolução pouco previsível. Mas de acordo com este argumento, admite-se que os seus processos podem levar a melhorias graduais no sistema de governação, com o seu próprio percurso, implementando acções que devem respeitar, em particular, a geografia do território. Abstract Addressing the running challenges of several greater cities, the institutional mark and regional planning are dimensions for improving metropolitan governance. Regarding the southwest European capital regions, what can be the innovations and differences in their currently processes and models? This paper proposes an applied framework to present the metropolitan governance analysis. Through a comparative case study methodology, various elements and interviews are qualitatively measured in the regions of Madrid, Barcelona, Paris and Lisbon. The conclusions find a tendency to balance between the efforts on those two regional metropolitan governance dimensions, which does not prevent to register their different paths: for example Ile-de-France has developed good initiatives in terms of planning, which then require some adjustments in the political mark, while Madrid had in recent years “less activity”, in result of his institutional stability. The Lisbon region maybe stays in an “intermediate position” with a dynamic evolution that is difficult to predict. But according to that argument, it’s possible to admit that his processes can gradually lead to small improvements in his governance system, with his own path, implementing actions that must respect, in particularly, the geography of the territory.
