Planeamiento y políticas de vivienda en el área metropolitana de Madrid durante la democracia (1975-2007)

La tesis analiza la realidad residencial construida en los municipios del Área Metropolitana de Madrid durante la democracia, en términos de localización, cantidad y calidad/cualidad, y su relación con el desarrollo de las políticas de planeamiento y de vivienda. La pregunta central que ha guiado la investigación es la siguiente: ¿cómo han incidido los instrumentos de política de vivienda y de planeamiento urbanístico en el crecimiento residencial de los municipios del Área Metropolitana de Madrid? Se trata de poner en relación dos políticas públicas orientadas por la Administración en sus distintos niveles de actuación: una de carácter territorial, el planeamiento urbanístico -cuya ejecución es de competencia municipal-, y otra de carácter sectorial, las políticas de vivienda -definidas por la Administración Central y Autonómica-. Al considerar la política de vivienda como el resultado de la política financiera, la política fiscal y la política de suelo, se ha observado cómo en España las dos primeras suponen más del 70% de la intervención presupuestaria en vivienda. Esta investigación se ha centrado particularmente en la tercera, la política de suelo, por su vinculación directa con el planeamiento urbanístico, pero sin dejar de tener en cuenta las dos primeras, no sólo por su implicación en el gasto público, sino porque han tenido tanto efecto, o más, en la conformación de la ciudad como ha podido tenerlo el planeamiento. La primera parte de la tesis se centra en el estudio de las políticas, sus objetivos e instrumentos (normativos y de planificación), mientras que en la segunda parte se analiza la realidad construida, por medio de una serie de variables e indicadores relacionados con la producción residencial (suelo y viviendas); en la tercera se presenta la parte de análisis y las conclusiones generales. Al cruzar los objetivos y los instrumentos de ambas políticas se ha podido concluir con una propuesta de periodización evidenciando las ontinuidades, cambios o transformaciones: después de una etapa de transición –de 1975 a 1978, coincide con los años de la transición democrática, en el que se definen las bases de las nuevas políticas-, se han podido diferenciar tres períodos: 1979-1989, 1990-1997 y 1998-2007. El primer período corresponde a los años en los que se fue construyendo todo el aparato institucional regulador con las nuevas administraciones que surgieron de la democracia. El segundo período, aunque comenzó con la aprobación de la Ley del Suelo de 1990 como instrumento clave del planeamiento regulador, se caracterizó por el cuestionamiento del modelo intervencionista y por los primeros planteamientos de liberalización. Finalmente, en el tercer período se pusieron las bases normativas de la liberalización del suelo en España, con la reforma de la Ley del Suelo de 1998 y otras medidas “remediales”. Finalmente, se presenta el análisis de los resultados sobre la realidad construida, teniendo como clave de interpretación la periodización propuesta a partir de las políticas, con el propósito de conocer cómo han podido incidir en el crecimiento residencial del AMM. Por tanto, la tesis aborda la inquietud de cuándo, cómo y dónde las políticas públicas han construido ciudad y han generado barrios, pues también trata de analizar los espacios urbanos que han sido el resultado físico de dichas políticas (aspectos de los conjuntos residenciales, el entorno inmediato y su relación con el tejido urbano existente), y no sólo de mostrar cantidades de viviendas construidas. Posteriormente, el estudio se centra en el análisis de las actuaciones públicas sobre suelos destinados a uno de los llamados “usos débiles”, las viviendas protegidas. Éstas se han beneficiado, de una u otra manera, de las ayudas económicas que se incluyen en los planes de vivienda y, por ello, están sujetas a unos parámetros definidos por la normativa vigente en cada caso. Ha interesado realizar una valoración de las mismas a partir de criterios de integración social y funcional, y de equilibrio territorial. ABSTRACT The PhD thesis analyses the residential areas built in the Metropolitan Area of Madrid, in terms of location, quality and quantity, and the relationship to the resulting built environment planning and housing policies. Its cover a period of tree decades since the onset of democracy in Spain in 1975 up to the beginning of the great recession starting 2007. The central question that has guided the research is the following: how the instruments of housing policy and urban planning have influenced the residential growth of the municipalities of the Metropolitan Area of Madrid? It is about putting together two different public policies that are also carried out at different levels of government: spacial and urban planning –whose execution is under municipal jurisdiction under principles and guidelines defined at a regional scale; and the sectorial housing policies which are mostly defined by the Nacional and Regional governments and are very interlinked with the wider economic policies of the country. When considering housing policy as the result of financial, fiscal and land policy, it has been noted in Spain that instruments under the first two types of measures (financial and fiscal) account for over 70% of the housing budget intervention. This research has particularly focused on the third, Land Policy, because of its direct link to urban planning. Nevertheless, the research also considers f inancial and f iscal pol icies, not only because of thei r signi f icant level of publ ic spending, but al so because of thei r great impacto n shaping the way the ci ty is bui l t . The first part of the thesis focuses on the study of the policies, objectives and instruments (housing and planning), while the second part analyses the built reality by means of a number of variables and indicators related to the housing production (land and housing). In the third part the analysis and general conclusions are presented. After relating the objectives and instruments of both policies, the thesis concludes with a proposal for periodization showing continuities, changes and transformations: after a transition period – from 1975 to 1978 coinciding with the years of the democratic transition, in which the basis of the new policies were defined- tree periods (1979-1989, 1990- 1997 and 1998-2007) have been d i s t i n g u i s h e d . The first period covers the years in which a new institutional apparatus wa s b u i l t wi t h t h e n e w a r r a n g eme n t s t h a t eme r g e d from democracy. The second period, even though it began with the approval of the Land Act 1990 as key element of the regulatory planning, was characterized by the questioning of public intervention and early approaches to liberalization. Finally, in the third period, the normative basis of liberalization was set up in Spain, with the reform of the Land Act 1998 and other “corrective” measures. At a final point, the analisys of the results on the reality constructed is presented having as a key of interpretation the periodization proposed. This provides tools for interpreting how policies did affect residential growth in the Metropolitan Area of Madrid. Therefore, the thesis addresses the issues of when, how and where public policies have inf luenced and guided the development of resident ial áreas in the región dur ing this t ime f rame. I t is also concerned with analysing those urban spaces that have been the physical result of such policies (aspects of residential complexes, the immediate environment and its relationship with the existing urban infraestructure), going beyond the analisys of statistical data. Subsequently, the study focuses on the analysis of public actions on land for the so-called "weak uses" particularly social housing. These have benefited in one way or another, of financial assistance included in housing plans and, therefore, are subject to some parameters defined by the regulations in force in each case.

La 'otra ciudad' funcionalista. El caso del Cabo de Las Huertas (1959-1979)

Se analiza la zona de la playa San Juan, el Cabo de las Huertas y la Albufereta, situadas a 5 km al NE de la ciudad de Alicante, durante el periodo (1959-79), en el contexto de la Dictadura y con el único marco legal de la Ley del Suelo española 1956. Cabría decir que, en 1963, aparece la Ley de Centros y Zonas de Interés Turístico Nacional. El cambio de las condiciones nacionales de 1959 propicia la urbanización de la playa de San Juan en el cabo de Huertas de Alicante que, ya formaba parte de una ambiciosa propuesta de 1933. Juan Guardiola Gaya, arquitecto catalán, redacta el plan parcial de esta franja de terrenos frente al mar para convertirla en un barrio turístico autónomo. Resulta significativo que elementos tradicionalmente antiurbanos como la naturaleza, los espacios libres y la arquitectura aislada son los que definan esta nueva ciudad para las vacaciones. De ahí que durante mucho tiempo estos núcleos turísticos vacíos en gran parte del año y constituidos solamente casi por segundas residencias no hayan sido considerados auténticas ciudades. Obviamente estos núcleos, a diferencia de las ciudades propiamente dichas, eran ciudades-satélites alojadas en la periferia litoral y cultural. No disponían de equipamiento suficiente pero tampoco contaban con industrias. Por el contrario, tenían más espacios libres. Utilizamos el término ciudad, a pesar de su tamaño, porque estaban pensadas para el comercio del tiempo libre. Eran las otras ciudades, las del verano para las vacaciones, como este caso.

Una aproximación a los instrumentos económicos de las leyes del suelo del 2008 y 2015. ¿Hacia un cambio en el modelo de desarrollo en España?

Tras la aprobación del Real Decreto Legislativo 2/2008 –Ley del Suelo–, nos encontramos ante un modelo territorial y un modelo de desarrollo, que acaba con el arcaico patrón de ciudad dispersa, encontrándose, no obstante, ante las gravísimas consecuencias espaciales generadas por la denominada “burbuja inmobiliaria”, unida a una crisis de consecuencias insospechadas, en el ámbito de la denominada globalización económica, de la que nuestro país no ha logrado sustraerse con Leyes vacías de instrumentos económicos que se han transferido a las Comunidades Autónomas, nos hallamos ante una oportunidad perdida fruto de una no siempre bien calculada descentralización. De este modo, en el presente artículo nos aproximamos a la importancia que muestran los denominados “instrumentos económicos” en la normativa que recoge los pormenores relacionados con el “suelo”, en España, en la primera de nuestras Leyes, la de 1956, en la de 2008 y en el recién aprobado Texto Refundido de la Ley del Suelo y Rehabilitación Urbana –Real Decreto Legislativo 7/2015–, en el ámbito estatal. Para ello, tras definir y valorar los enfoques conceptuales relativos al “suelo” y sus tipologías, se concretan y estudian los instrumentos económicos que se recogen en la Ley del Suelo española y su relación con las nuevas formas de “hacer ciudad”.

Relações interétnicas em conflito entre Makuxi e Wapixana na terra indígena Raposa Serra do Sol

This dissertation present an analysis of the interethnic conflict between Makuxi and Wapixana at the current moment in the Maloca of the Adobe, Aboriginal Land Fox-Mountain range of the Sun, in the State of Roraima. The theoretical field was boarded in the Ethnology, pursuing situations in local history, with edges in ethno-history. The research elapsed of the deepening necessity on the social relations and aboriginal politics, for the intercultural professional exercise of educator, appealing the bibliographical survey and participant comment as method; not directive interviews, photographs, filmings and daily register in of field, as techniques carried through in the period of 2006 to 2007. Although to inhabit in the same area and to establish marriages between itself, individuals and groups express tensions, aggravated with the landmark and legal recognition of the area, which generated inter dispute and intraetnias, mainly with the intrusion of farmers, rizicultores and the form of governmental influence. A relation of rivalry, individual and collective was evidenced, suggesting the strengthenig and not it fractionly, of the fights external politics, interns and in way to the cultural diversity and social adversity

Influence of historic land use change on the biosphere-atmosphere-exchange of C and N trace gases in the humid, subtropical region of Queensland

Increases in atmospheric concentrations of the greenhouse gases (GHGs) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) due to human activities have been linked to climate change. GHG emissions from land use change and agriculture have been identified as significant contributors to both Australia’s and the global GHG budget. This is expected to increase over the coming decades as rates of agriculture intensification and land use change accelerate to support population growth and food production. Limited data exists on CO2, CH4 and N2O trace gas fluxes from subtropical or tropical soils and land uses. To develop effective mitigation strategies a full global warming potential (GWP) accounting methodology is required that includes emissions of the three primary greenhouse gases. Mitigation strategies that focus on one gas only can inadvertently increase emissions of another. For this reason, detailed inventories of GHGs from soils and vegetation under individual land uses are urgently required for subtropical Australia. This study aimed to quantify GHG emissions over two consecutive years from three major land uses; a well-established, unfertilized subtropical grass-legume pasture, a 30 year (lychee) orchard and a remnant subtropical Gallery rainforest, all located near Mooloolah, Queensland. GHG fluxes were measured using a combination of high resolution automated sampling, coarser spatial manual sampling and laboratory incubations. Comparison between the land uses revealed that land use change can have a substantial impact on the GWP on a landscape long after the deforestation event. The conversion of rainforest to agricultural land resulted in as much as a 17 fold increase in GWP, from 251 kg CO2 eq. ha-1 yr-1 in the rainforest to 889 kg CO2 eq. ha-1 yr-1 in the pasture to 2538 kg CO2 eq. ha-1 yr-1 in the lychee plantation. This increase resulted from altered N cycling and a reduction in the aerobic capacity of the soil in the pasture and lychee systems, enhancing denitrification and nitrification events, and reducing atmospheric CH4 uptake in the soil. High infiltration, drainage and subsequent soil aeration under the rainforest limited N2O loss, as well as promoting CH4 uptake of 11.2 g CH4-C ha-1 day-1. This was among the highest reported for rainforest systems, indicating that aerated subtropical rainforests can act as substantial sink of CH4. Interannual climatic variation resulted in significantly higher N2O emission from the pasture during 2008 (5.7 g N2O-N ha day) compared to 2007 (3.9 g N2O-N ha day), despite receiving nearly 500 mm less rainfall. Nitrous oxide emissions from the pasture were highest during the summer months and were highly episodic, related more to the magnitude and distribution of rain events rather than soil moisture alone. Mean N2O emissions from the lychee plantation increased from an average of 4.0 g N2O-N ha-1 day-1, to 19.8 g N2O-N ha-1 day-1 following a split application of N fertilizer (560 kg N ha-1, equivalent to 1 kg N tree-1). The timing of the split application was found to be critical to N2O emissions, with over twice as much lost following an application in spring (emission factor (EF): 1.79%) compared to autumn (EF: 0.91%). This was attributed to the hot and moist climatic conditions and a reduction in plant N uptake during the spring creating conditions conducive to N2O loss. These findings demonstrate that land use change in subtropical Australia can be a significant source of GHGs. Moreover, the study shows that modifying the timing of fertilizer application can be an efficient way of reducing GHG emissions from subtropical horticulture.

Amendments to the Land Title Act 1994 (Qld)

Wholesale amendments to the Land Title Act 1994 (Qld) were recently introduced with the passing of the Natural Resources and Other Legislation Amendment Act 2005 (Qld). The amendments were preceded by an extensive review of issues associated with the operation of the freehold land register and consultation with a number of stakeholders. The three articles that follow address different issues associated with these statutory amendments. The first article provides a brief overview of the amendments. The second article deals with particular amendments designed to combat mortgage fraud. In the third article, the question posed is whether further statutory amendment could better protect unregistered interests.
