Ecuador, país sudamericano, aprobó en el año 2008 una Constitución en la que subyace un modelo de desarrollo humano multidimensional y alternativo al vigente. Sus dimensiones sociales, económicas, políticas, culturales y ambientales se encuentran en los textos correspondientes a los “Derechos”, “Régimen de Desarrollo” y “Régimen del Buen Vivir”; en tanto que las dimensiones territoriales se hallan expuestas en la “Organización Territorial del Estado”, conformada por regiones, provincias, cantones y parroquias rurales, con sus respectivos gobiernos autónomos descentralizados, a los que la misma Constitución les atribuye, entre otras, las competencias exclusivas de “planificar el desarrollo” y “formular los correspondientes planes de ordenamiento territorial”, y al Estado central la “planificación nacional”. No obstante, el marco legal dictado posteriormente -que otorga al Estado central la competencia de ordenación territorial, mediante la “Estrategia Territorial Nacional”-, no logra regular con eficacia, efectividad y eficiencia este ejercicio competencial, incluyendo en esta condición a los lineamientos técnicos dictados por el organismo nacional de planificación; volviendo urgente la vigencia de una ley que lo asuma, pero que demanda previamente el diseño de un modelo de gestión de estas competencias, propósito al cual procura contribuir el presente trabajo. Su estructura es la siguiente: Capítulo 1: “La problemática, objetivos y antecedentes”, en cuya formulación se destaca el estudio del marco jurídico y técnico vigente en relación a la ordenación territorial, partiendo de una breve visión sobre los empeños previos en Ecuador por adoptarla, y que se complementa con una evaluación preliminar de la experiencia vivida por los gobiernos autónomos descentralizados al formular y gestionar sus primeros planes de desarrollo y de ordenación territorial, en acatamiento del mandato constitucional. Luego se avanza en la definición del objetivo general del trabajo y de un conjunto coherente de objetivos específicos. Concluye este capítulo con el análisis del estado de la cuestión: los antecedentes sobre la ordenación territorial en América Latina, en el marco de sus predecesoras históricas. Capítulo 2: “Diseño del modelo de gestión”, que se inicia con el planteamiento de la metodología a seguir, condicionada especialmente por los propios textos constitucionales que vinculan en la relación de “correspondencia” a la ordenación territorial con la planificación del desarrollo y en consecuencia con el ejercicio de las competencias sectoriales asignadas por ella misma a los diferentes niveles de gobierno. Efectivamente, tal relación supone básicamente que la planificación del desarrollo adquiera el carácter de global, total, vale decir integral, en el sentido de que igualmente contemple sus dimensiones territoriales y que la planificación de éstas se integre a la de las dimensiones sociales, económicas, políticas, culturales y ambientales, de manera tal que en cada uno de los niveles la planificación del desarrollo sea un proceso único y un todo. Por estas condiciones, el diseño en cuestión demanda el tratamiento previo de los aspectos contemplados por la metodología en relación con la conceptualización y ordenamiento de la planificación y gestión del modelo de desarrollo humano previsto por la Constitución para los distintos niveles territoriales, seguido del análisis y evaluación del reparto competencial. En este marco se diseña el modelo de gestión en siete componentes específicos que definen los objetivos estratégicos generales a los cuales apuntará la ordenación territorial, estructuran con sus figuras –los planes–, un sistema integrado de alcance nacional, entienden al propio territorio bajo una visión sistémica y proponen un esquema metodológico general para la redacción de tales instrumentos. Luego se aborda en calidad de tema clave, la articulación con la planificación del desarrollo, el establecimiento de las dimensiones territoriales sectoriales y globales de ordenación en cada nivel territorial, que posibilita a su vez la formulación de los contenidos de las determinaciones de los planes y la definición de un conjunto de lineamientos para su gestión. Capítulo 3. “Verificación”, que se ha concretado en la puesta a consideración de un selecto grupo de expertos nacionales en ordenación territorial, el modelo propuesto siguiendo los procedimientos recomendados para este tipo de consultas. Capítulo 4. “Conclusiones Generales”, esto es, un conjunto coherente de proposiciones que condensan los resultados alcanzados en los diferentes capítulos precedentes y que demuestran la validez del modelo propuesto. ABSTRACT Ecuador approved a constitution, by 2008, where a multidimensional human development model, different to the one in force, underlies. Its social, economic, political, cultural and environmental dimensions are at the entries for "Rights", "Development Scheme" and "Rules of Good Living"; while the territorial dimensions are given by the "Territorial Organization of the State" section, consisting of regions, provinces, cantons and rural parishes, with their respective autonomous governments, to which the Constitution conferred, inter alia, the exclusive powers of "development planning" and "land use plan formulation," while the central state has the "national planning" competence. However, the subsequent issued legal framework - which gives the central state competences over land planning, using the "National Spatial Strategy" - fails to effectively regulate this exercise of jurisdiction, including in this condition the technical guidelines dictated by the national planning agency; thus becoming urgent to put in force a law that assume it, which demands the previous design of a management model of these competences, which is the aim that seeks to contribute the present work. Its structure is as follows: Chapter 1: "The problem, objectives and background" that includes the study of the legal and technical framework in force in relation to land planning, starts with a brief overview of previous efforts to adopt it in Ecuador. The chapter is complemented with a preliminary assessment of the experience of the autonomous governments to formulate and manage their early development plans and land planning, in compliance with the constitutional mandate. Subsequently the overall objective of the work and a coherent set of objectives are defined. This chapter concludes with an analysis of the state of art: the history of land use planning in Latin America in the context of their historical predecessors. Chapter 2, "Design of a management model", which begins with the methodological approach to follow, conditioned by the constitutional texts linking the relationship of "correspondence" land planning with development planning and with the exercise of the sectorial competences assigned by itself to different levels of government. Indeed, such a relationship basically means that development planning should acquire a global, comprehensive, complete, total, character in the sense that it also provides for their territorial dimensions and that their planning is integrated to social, economic, political, cultural and environmental factors, so that in each of the levels, development planning is a unique process and a whole. For these conditions, the design in question demands pretreatment of the aspects covered by the methodology in relation to the conceptualization and management of the planning and management of human development model envisaged by the Constitution to the various territorial levels, followed by analysis and evaluation of the distribution of powers. In this framework a management model is designed into seven specific components that define the overall strategic objectives which aim to land planning, structure plans, and an integrated nationwide system, that understand the territory under a systemic vision and propose a general methodological framework to draft these instruments. Then a key issue is addressed, the coordination with development planning, the establishment of sectorial and regional and global dimensions of management at each territorial level, which in turn allows the formulation of the contents of the plans determinations and defining a set of management guidelines. Chapter 3, "Verification", It has traduced into asking for the revision of the proposed model by a select group of national experts in spatial planning by following recommended procedures for such queries. Chapter 4, "General Conclusions", a coherent set of propositions that summarize the results obtained in the different preceding chapters, which demonstrates the validity of the proposed model.

Channel cbanges are the consequence of cbanges in sediment yield from the slopes and in the connectivity between slopes and channels bccause of distinct land use and climate inJpacts. In Ibis study, we investigated the characteristics and evolution of a short reach in the headwater of the !juez River, central-soutbem Pyrenees. Assessment of a series of sedimentar)' and geomorphic structures confirtned major cbanges to the valley boUom, mainly related to changes in the intensity of human activity. 'The oldest sedimentar)' structure is a terrace leve! located 3 10 4 m above the current alluvial plain. General deforestation, overgrazing and recwring tires in the montane belt ( 1100-1600 m a.sJ.) have led 10 increased soil erosioo and connectivity, and to tbe triggering of debris llows thal have been deposited on the fluvial tmace. Woody fragments from within the debris llows were dated using acceleraror mass spectrOmetry '"e radiocaroon tcchniques (AMS), yielding ages between 1 00 and 115 cal years BP, whicb coincides with tbe period of maximum deforestalion and human density in the Pyrenees. Depopulation and fannland abaodonment since tbe beginning of tbe 2001 oenrury has resulled in generalliJcod natural and artificial reforestation, a shrinkage of the eroded arcas aod a decline in connectivi¡y bdween slopes and the channel. 1be rnost impor1an1 consequence has been cbannel incision and oarrowing, and the development of a sedimed annour !ayer. Active sedimenl b8llSpOI1 is continui.Qg, although there has been a decrease in sed.iment yield from the slopes. Copyright O 2014 John Wiley & Soos, Ltd.

La determinación del valor del suelo implicado en los procesos de urbanización se mueve en una compleja dialéctica en la que algunos fenómenos de naturaleza morfológica como el modelado del espacio social, o el que se deduce de las determinaciones del planeamiento (aprovechamiento especialmente) se enfrentan a instrumentos de regulación que se rigen por normas de carácter administrativo (urbanísticas y expropiatorias, fiscales, financieras-hipotecarias etc.). En ese marco en el que las discrepancias son frecuentes se pretende analizar las posibles actuaciones encaminadas a influir sobre la formación de ese valor en el sentido de limitar las expectativas de aprovechamiento tradicionalmente vinculadas al sistema urbanístico establecido, destacando al respecto la implantación de criterios de sostenibilidad y participación ciudadana, así como que la utilización de normas administrativas de valoración con la finalidad de reducir tales expectativas y tratar de influir sobre el sistema urbanístico en su conjunto, no se considera suficiente para conseguir el logro de tales objetivos. Añadiendo, respecto del conjunto de normas administrativas de determinación del valor del suelo, que si bien las reglas urbanísticas y expropiatorias establecen actualmente reglas objetivas de valoración, a través de la normativa de valoración destinada a entidades financieras, o de carácter fiscal, se introducen criterios subjetivos que tratan de aproximarse al mercado, incluso en el caso del valor catastral, estructuralmente reglado. Esta separación de criterios ha llevado a un enfrentamiento al que ha venido a dar respuesta la reciente sentencia del Tribunal Supremo de 30 de mayo de 2014, que impone los criterios urbanísticos de consideración de situaciones básicas de suelo, frente a los fiscalmente regulados en relación con la normativa catastral en cuanto a la consideración de suelo urbanizable sin desarrollar, que pasa a ser considerado como en situación rural, siendo por tanto aplicables sobre el mismo las reglas de valoración que la normativa catastral establece para esta categoría de suelo (rústico) que no considera, incluso con la posterior modificación, de junio de 2015, incorporada para adaptarse a la mencionada sentencia, expectativas de aprovechamiento. Pero como se ha señalado, la exclusiva utilización de la normativa urbanística de valoración no se considera suficiente para evitar los efectos que sobre el valor de suelo produce la asignación de tales aprovechamientos, por lo que acuerdo con la actual legislación de suelo, deben asimismo potenciarse actuaciones encaminadas a un desarrollo sostenible así como a la participación ciudadana, la transparencia y el control, con la finalidad de lograr un mayor rigor en la utilización del suelo que ha de traducirse en su valoración. ABSTRACT Determining the land value involved in the urbanisation process implies a complex dialectic in which certain morphological natural phenomena like the modelling of social space or that deduced from planning determinations (especially land use) face regulatory instruments governed by administrative norms (urban planning and expropriator, tax, financial-mortgage etc.). In this context where discrepancies are common, the purpose is to analyse the possible actions geared to influence the formation of that value in the sense of limiting land use expectations traditionally linked to the established urban planning system, highlighting the implementation of sustainability criteria and citizen participation, as well as to consider that the administrative standards of evaluation for reducing said expectations, and trying to influence the urban system as a whole, are not considered sufficient for achieving these objectives. We might add, with respect to the set of administrative norms for determining the land value, that while urban and expropriations norms currently provide objective rules of valuation, subjective criteria are introduced trying to approach the market, including the structurally regulated cadastral value through valuation rules aimed at financial or fiscal institutions. This separation of criteria has led to a confrontation to which the recent ruling of the Supreme Court of May 30, 2014 responds. The aforementioned judgement imposes the urban core criteria for basic land use situations against those fiscally regulated in relation to cadastral regulations regarding the consideration of undeveloped building land, which is considered to be in a rural situation, making it subject to the same rules that cadastral valuation norms established for this category of land use (rustic) which do not consider, even with the subsequent amendment of June 2015, introduced to fit that judgment, use expectations. But as noted, the exclusive use of valuation planning regulations is not considered sufficient to avoid the effects on the land value produced by the allocation of said uses, so that according to the current land use legislation, actions aimed at sustainable development as well as citizen participation, transparency and control, shall be enhanced in order to achieve greater rigor in the use of land which should be translated in their valuation.

As the population of Colorado continues to grow, the impacts from individual sewage disposal systems, or onsite wastewater systems (OWS), are becoming more apparent. Increased use of OWS impacts not only water quality but land use and development as well. These impacts have led to the need for a new generation of wastewater regulations in the state, a transition from the historic prescriptive requirements to a more progressive, performance-based system. A performance-based system will allow smarter growth, improved water quality, and cost savings for both the regulatory agencies and the OWS industry in Colorado. This project outlines the challenges and essential elements required to make this transition, and provides guidance on how to meet the challenges and overcome barriers to implementing a performance code in Colorado.

Using information from two recently published atlases of threatened invertebrate species in peninsular Spain, we examined the climatic, land use and geographic characteristics of the 100 km2 UTM cells with most likelihood of suffering extinctions (extinction cells), as well as the attributes of the species prone to population extinctions. Extinction cells have had significantly (1) lower precipitation values, (2) higher temperatures, (3) higher percentages of anthropic land uses or (4) higher rates of anthropization during the last 20 years than the remaining cells. Nevertheless, probable extinctions may occur under a wide range of climatic and anthropization change rates and these variables can only explain a low proportion (~5 %) of variability in the occurrence or number of extinction cells. Aquatic species seem to suffer higher local extinction rates than terrestrial species. Interestingly, many invertebrate species with approximately 25 or less occurrence cells are on a clear trajectory towards extinction. These results outline the difficulties and uncertainties in relating probable population extinctions with climatic and land use changes in the case of invertebrate data. However, they also suggest that a third of the considered Spanish threatened species could have lost some of their populations, and that current conservation efforts are insufficient to reverse this tendency.

New archaeological survey data are combined with previous evidence to examine the rural landscape during the Iberian Iron Age in the Valencia region of eastern Spain. One goal was to understand the settlement pattern and agricultural intensification through manuring. The second objective was to address the socioeconomic aspects of changes in the landscape. It is possible to trace the emergence of a hierarchical settlement pattern in the Iberian Iron Age in which large fortified settlements carried out the most important functions of control and exploitation of the territory, extending their authority over small rural villages and farmsteads. This pattern is associated with the complex socioeconomic structures and political organization of early Iberian states.

Traditional water supply systems in semi-arid agrarian ecosystems, mainly irrigation canals, contribute to the diversity of the landscape and influence the composition of species. To evaluate their effect on bird communities in the breeding season, we selected a rural area in southeastern Spain, where an intricate and extensive network of irrigation canals and cultivated areas is located between two wetlands declared as Natural Parks. Birds were counted at representative points distributed throughout the canal network at which we recorded several variables related to the physical features, the vertical and horizontal structure of associated vegetation, reed development (Phragmites australis) and land use in the neighboring areas. We detected 37 bird species, most of which were also breeding in the wetlands nearby. We used Hierarchical Partitioning analyses to identify the variables most strongly related to the probability of the presence of selected species and species richness. Vegetation cover and height close to the canals, together with reed development, were the most important types of variables explaining species presence and richness. We found that current management practices for reeds in canals are not well-suited for biodiversity conservation. We therefore propose alternatives that could be implemented in the area in cooperation with stakeholders.
