Land use modelling and the role of stakeholders in natural protected areas: the case of Doñana national park, Spain

Doñana, a National Park since 1969, a UNESCO site since 1994 among other protected area designations of national and international character, is a coastal dune and marshland ecosystem of outstanding importance for biodiversity and conservation at the mouth of the Guadalaquivir River, Southwest Spain. However, the Doñana natural area is seriously threatened by global change factors such as humanly induced climate change, habitat loss, overexploitation of ecosystem services, and pollution. Not all stakeholders are convinced of the benefits of the national park, and management of Doñana, its environs and watershed are the subject of intense disagreement. This interplay between natural characteristics of great value with intense human pressure makes Doñana a fascinating workshop for the study of global human environment interactions. Here, we discuss the role of stakeholders in the application of a cellular automatabased model to Doñana and its environs and present the results of a series of exercises undertaken with stakeholders to parametrize the model, something often done by researchers without stakeholder engagement. By engaging with stakeholders early in the project, feedback generated from workshops contributes to model development. Stakeholders are therefore contributors of empirical data for the model as well as independent evaluators providing local and specialist knowledge.

Determinación de los parámetros de diseño a aplicar al proyecto de grandes yates a motor, en base a nuevos requerimientos de eficiencia energética y protección del medioambiente marino

Durante los últimos años, la construcción de grandes yates ha evolucionado hacia conceptos y diseños más complejos dónde se ha priorizado en muchas ocasiones la estética arquitectónica y exigencias de confort de los armadores y operadores dejando en segundo plano aspectos clave de seguridad. Diferentes Organismos Internacionales y las Sociedades de Clasificación han venido adaptando sus requisitos a la problemática específica de este tipo de buques, tratando de compatibilizar tendencias de diseño con exigencias de resistencia, integridad estructural, estanqueidad y seguridad entre otras. En la actualidad, la construcción de grandes yates con esloras incluso por encima de los 100 metros, el aumento del número de pasajeros por encima del límite tradicional de 12, las nuevas tendencias de ahorro energético y protección medioambiental que se están implantando en la industria en general y marítima en particular, plantean una serie de desafíos tanto a los diseñadores como a las Sociedades de Clasificación que deben avanzar en sus reglamentaciones para cubrir estos y otros aspectos. Son precisamente estos aspectos medioambientales, tradicionalmente relegados en la industria de grandes yates los que están ocupando en la actualidad un primer plano en los desarrollos de normativa de diferentes Organismos Internacionales y Nacionales. El impacto que estas nuevas normativas van a tener sobre el diseño de grandes yates a motor centra el desarrollo de esta Tesis. Hasta donde ha podido conocer el doctorando, esta es la primera vez que en una Tesis Doctoral se abordan los principales mecanismos que regulan el diseño y la construcción de grandes yates a motor, se estudian y analizan las regulaciones internacionales en materia de protección medioambiental y de eficiencia energética aplicables a los yates, se seleccionan y describen un conjunto de tecnologías maduras de carácter medioambiental, susceptibles de ser empleadas en yates y se determina los parámetros y aspectos del diseño a aplicar al proyecto de grandes yates a motor como resultado de la aplicación de estas tecnologías, analizados bajo la perspectiva de la Sociedad de Clasificación y de los Organismos Internacionales. La Tesis comienza con un análisis de la industria de construcción de grandes yates, la flota existente de grandes yates, la cartera actual de pedidos y la evolución esperada del mercado. Aquí se pone de manifiesto que a pesar de la crisis económica global de los últimos años, este mercado goza relativamente de buena salud y las previsiones son favorables, particularmente para el sector en Europa. A continuación se aborda el estado del arte del diseño de yate grande, sus peculiaridades, particularmente estructurales y de armamento, que le diferencian de otros tipos de buques y las tendencias en su diseño. Se pone de manifiesto cómo el proyecto de estos yates ha evolucionado hacia yates de gran tamaño y complejidad técnica, debido a la demanda y necesidades actuales y cómo ha influido en aspectos como la disposición estructural. Seguidamente se describen los principales mecanismos que regulan el diseño y construcción de grandes yates, particularmente el Código de Grandes Yates Comerciales de la Maritime & Coastguard Agency del Reino Unido, y las Reglas y Reglamentos de la Sociedad de Clasificación Lloyd’s Register para la Clasificación de yates; por ser ambas organizaciones las que lideran el Registro y la Clasificación respectivamente de este tipo de buques, objeto del estudio. El doctorando ejerce su actividad profesional como inspector de Lloyd’s Register en una oficina técnica de apoyo y evaluación de diseño, siendo especialista en grandes yates, lo que ha permitido exponer de primera mano el punto de vista de la Sociedad de Clasificación. En el siguiente Capítulo se describen las principales reglamentaciones internacionales de carácter medioambiental que afectan al diseño, construcción y operación de los yates, algunas de las cuales, como es el caso del Convenio Internacional para el Control y la Gestión del Agua de Lastre y Sedimentos de los buques (BWM 2004) aún no ha entrado en vigor a la fecha de terminación de esta Tesis. Seguidamente se realiza una selección de tecnologías desde el punto de vista de protección medioambiental y ahorro energético y su aplicación al diseño y construcción de grandes yates. Algunas de estas tecnologías son maduras y ya habían sido utilizadas con éxito en otros tipos de buques, pero su aplicación a los yates entraña ciertos desafíos que se describen en este Capítulo. A continuación se determinan y analizan los principales parámetros de diseño de los yates grandes a motor como consecuencia de las tecnologías estudiadas y se indican una serie de aspectos de diseño bajo la perspectiva de la Sociedad de Clasificación y de los Organismos Marítimos Internacionales. Finalmente se llega a una serie de conclusiones y se identifican futuras líneas de investigación en relación a las tecnologías descritas en este trabajo. ABSTRACT In recent years, the building of large yachts has evolved into more complex concepts and designs where often prioritized architectural aesthetics and comfort requirements of owners and operators leaving in the background key security aspects. Several international organizations and classification societies have been adapting their requirements to the specific problems of this type of vessel, trying to reconcile demands design trends with resistance, structural integrity, watertightness and safety among others. At present, the building of large yachts with lengths even above 100 meters, the increase in passenger numbers over the traditional limit of 12, new trends of energy saving and environmental protection are being implemented in the marine industry in particular, they pose a number of challenges to both designers and classification societies that should update and improve their regulations to cover these and other aspects. It is precisely these environmental issues, traditionally relegated to the large yacht industry, which are currently occupying center stage in the development of rules of different international and national bodies. The impact that these new standards will have on the design of large motor yachts focuses the development of this thesis. As far as it is known, this is the first time in a doctoral thesis the main mechanisms regulating the design and construction of large motor yachts are addressed, the international regulations on environmental protection and energy efficiency requirements for yachts are studied and analyzed, a set of mature environmental technologies, capable of being applied to yachts are selected and described, the parameters and design aspects to be applied to large yacht projects as a result of the application of these technologies are determined and analyzed from the perspective of the Classification Society and international organizations. The thesis begins with an analysis of the shipbuilding industry of large yachts, the existing fleet of large yachts, the current backlog and the expected market developments. Here it becomes clear that despite the global economic crisis of recent years, this market enjoys relatively good health and prospects are favorable, particularly for the sector in Europe. Then the state of the art of large yacht design, its peculiarities, particularly structural and outfitting, that differentiate it from other types of ships and trends in design is discussed. It shows how the project of these yachts has evolved to large yachts and technical complexity, due to the demand and needs and how it has influenced the structural arrangement aspects. Then the main mechanisms regulating the design and construction of large yachts, particularly the Large Commercial Yacht Code developed by the Maritime & Coastguard Agency (UK) and the Lloyd’s Register Rules & Regulations for the Classification of Special Service Craft including yachts are described; the two organizations to be leading the registration and classification respectively of such vessels under study. The doctoral student practices his profession as a senior specialist to Lloyd’s Register in a technical support office, dealing with the design assessment of large yachts, which allowed exposing firsthand view of the Classification Society. In the next chapter describes the main international environmental regulations, affecting the design, construction and operation of yachts, some of which, such as the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM 2004) has not yet entered into force at the date of completion of this thesis. Following is a selection of technologies from the point of view of environmental protection and energy saving and its application to design and construction of large yachts. Some of these technologies are mature and have already been used successfully in other ship types, but their application to yachts entails certain challenges that are described in this chapter. Then identifies and analyzes the main design parameters of large motor yachts as a result of the technologies studied and a number of design aspects are given from the perspective of Classification Society and international maritime organizations. Finally, a number of conclusions are exposed, and future research is identified in relation to the technologies described in this Thesis.

E-comparisons: A new approach to round robin tests for environmental noise assessment in transport infrastructures

The increasing importance of pollutant noise has led to the creation of many new noise testing laboratories in recent years. For this reason and due to the legal implications that noise reporting may have, it is necessary to create procedures intended to guarantee the quality of the testing and its results. For instance, the ISO/IEC standard 17025:2005 specifies general requirements for the competence of testing laboratories. In this standard, interlaboratory comparisons are one of the main measures that must be applied to guarantee the quality of laboratories when applying specific methodologies for testing. In the specific case of environmental noise, round robin tests are usually difficult to design, as it is difficult to find scenarios that can be available and controlled while the participants carry out the measurements. Monitoring and controlling the factors that can influence the measurements (source emissions, propagation, background noise…) is not usually affordable, so the most extended solution is to create very effortless scenarios, where most of the factors that can have an influence on the results are excluded (sampling, processing of results, background noise, source detection…) The new approach described in this paper only requires the organizer to make actual measurements (or prepare virtual ones). Applying and interpreting a common reference document (standard, regulation…), the participants must analyze these input data independently to provide the results, which will be compared among the participants. The measurement costs are severely reduced for the participants, there is no need to monitor the scenario conditions, and almost any relevant factor can be included in this methodology

Consequences of different meteorological scenarios in the environmental impact assessment of tritium in air

The environmental impact of systems managing large (kg) tritium amount represents a public scrutiny issue for the next coming fusion facilities as ITER and DEMO. Furthermore, potentially new dose limits imposed by international regulations (ICRP) shall impact next coming devices designs and the overall costs of fusion technology deployment. Refined environmental tritium dose impact assessment schemes are then overwhelming. Detailed assessments can be procured from the knowledge of the real boundary conditions of the primary tritium discharge phase into atmosphere (low levels) and into soils. Lagrangian dispersion models using real-time meteorological and topographic data provide a strong refinement. Advance simulation tools are being developed in this sense. The tool integrates a numerical model output records from European Centre for Medium range Weather Forecast (ECMWF) with a lagrangian atmospheric dispersion model (FLEXPART). The composite model ECMWF/FLEXTRA results can be coupled with tritium dose secondary phase pathway assessment tools. Nominal tritium discharge operational reference and selected incidental ITER-like plant systems tritium form source terms have been assumed. The realtime daily data and mesh-refined records together with lagrangian dispersion model approach provide accurate results for doses to population by inhalation or ingestion in the secondary phase

Metodología para medir los efectos de la aplicación de estándares sobre la industria de los medios de pagos en el mercado chileno

Cada vez juegan un rol más relevante en nuestra vida las tecnologías de información, desde nuestros hogares hasta las empresas y gobiernos acceden a grandes volúmenes de datos e información, las comunicaciones ya no tienen impedimentos de distancias, un comprador y un vendedor puede estar en cualquier lugar, un producto que es adquirido en un comercio en Santiago a través de un medio de pago (tarjeta de crédito) en menos de un segundo la transacción va desde Chile a solicitar autorización en Singapur para ser aprobada. En la sociedad tanto oferentes como demandantes cuentan con información disponible en línea para la toma de decisiones. Existe una mayor apertura e integración económica iniciada con las redes comerciales, donde existen enfoques regionales y multilateral, que han impulsado la apertura del comercio y la integración económica. Son múltiples los tratados de libre comercio que apoyan al desarrollo económico, donde las crisis mundiales han afectado tanto las economías como el transporte, considerando que en el comercio internacional cerca del 90% se desarrolla a través de los puertos, es importante identificar relaciones entre el desarrollo de los medios de pago y el comercio electrónico a través de los puertos. Nuestra investigación busca integrar tanto aspectos de investigación científica como como investigación aplicada, de modo que sea un aporte al día a día de empresas en el sector de los medios de pago en Chile y quienes diseñan y definen la aplicación de normas y estándares. Esta tesis plantea una metodológica para analizar las relaciones entre la aplicación de estándares y sus efectos en la industria de los medios de pago en Chile. Este trabajo de investigación nos permitirá identificar entorno, variables que intervienen y evolución del mercado de los medios de pago, a través de un relevamiento del estado del arte de los medios de Pago en la industria Bancaria chilena. Buscaremos en el mercado de los medios de pago en la industria Chilena - sector Bancario, relaciones entre la aplicación de estándares y sus efectos en los volúmenes transaccionales, analizaremos las tendencias de los medios de pago y el desarrollo comercial del Puerto de Valparaíso. Se busca a través de esta metodológica poder mejorar la toma de decisiones en la industria de los medios de pago en Chile con una mejor gestión y uso de recursos. Every day information technology plays a greater role in our lives, from our homes to businesses, to how governments access large volumes of data and information. Communication is no longer hindered by distances, as a buyer and seller can be anywhere. A product that is purchased in a shop in Santiago through a payment option (credit card) in less than a second, a transaction will request authorization from Chile to Singapore to be approved. In this society both buyers and sellers have access to online information that is available for decision making. There is greater openness and economic integration that has begun within the commercial networks, in which there are regional and multilateral approaches that has helped expand trade and economic integration. Likewise, there are numerous free trade agreements that support economic development; however, the global crisis has affected economies like transportation. In regards to international commerce about 90% is developed through the ports, considering that the former is important to identify the relationships between the development of the payment options and e-commerce at the ports. Our research aims to integrate both the scientific research and applied research aspects, so that this will be a contribution to the day to day business for the payment options in Chile, and for those who design and define the application of norms and standards. This thesis offers a methodology to analyze the relationships between the application of standards and its affects in the industry of payment options in Chile. This research will allow us to identify the environmental variables that intervene and evolve the market of the payment options, through the analysis of the state of the art in the payment options in the Chilean Banking industry. In the market of the payment industry options we have looked specifically at the Chilean Banking industry and the relationship between the application of standards and their impact on transaction volumes. In addition, there has been an analysis of the activity of the payment options and wire transfers in the maritime industry in Valparaíso in order to define the feasibility of a model that allows us to relate these effects in these markets and the application of standards. We have searched the Chilean banking industry for the relationships between the application of standards and its effect on transaction volumes, in order to analyze the trends in the payment options and the commercial development at the Port of Valparaiso. Therefore, through the use of this methodology we look to be able to make better decisions in the payment options industry in Chile, with better management and use of the resources.

Characterization of the environmental performance of the insulating materials in the enveloping of the building.

Insulating materials in buildings are one of the main factors that should be taken into account when talking about sustainability since with a correct application it could imply important savings for the citizens. In the course of its life, a building requires a series of supplies to perform the duties it has been built for, generating an impact on the environment. The selection of one material or another will establish partly the global environmental impact of the building. Choosing the right insulating material will determine the building's general degree of sustainability, both in its heating savings (energy consumption) and in the environmental impacts caused by its LCA (greenhouse gas emissions). Therefore, we propose to establish guidelines to characterize the insulating material with a better environmental performance in all the stages of its life cycle, taking into account the construction system, the use of the building and its location.

Urbanization, socio-economic changes and population growth in Brazil: dietary shifts and environmental implications.

Population growth, economic globalization, improving living standards and urbanization are causing important changes in the global food system and modifying the dietary habits in many parts of the world (Molden, 2007; Godfray et al., 2010). The nutritional transition (linked to the development of countries and the increasing wealth of its population) implies a shift away from traditional staple food such as roots and tuber vegetables and a rise in consumption of meat and milk products, refined and processed foods, as well as sugars, oils and fats (Ambler-Edwards et al., 2009). The contemporary food system puts significant pressure on natural resources, especially on land and water, because the growing food demand pushes the agricultural frontier beyond, causing large impacts on ecosystems (Ambler-Edwards et al. 2009: 11-18). Also, the trend towards richer diets in animal proteins and processed food adds further pressure on the environment, since it requires larger amount of water and land to be produced (Allan, 2011; Mekonnen and Hoekstra, 2012).

The role of land and water for trade and food production in Latin America: Environmental trade-offs of agricultural intensification versus extensification

One of humanity’s major challenges of the 21st century will be meeting future food demands on an increasingly resource constrained-planet. Global food production will have to rise by 70 percent between 2000 and 2050 to meet effective demand which poses major challenges to food production systems. Doing so without compromising environmental integrity is an even greater challenge. This study looks at the interdependencies between land and water resources, agricultural production and environmental outcomes in Latin America and the Caribbean (LAC), an area of growing importance in international agricultural markets. Special emphasis is given to the role of LAC’s agriculture for (a) global food security and (b) environmental sustainability. We use the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT)—a global dynamic partial equilibrium model of the agricultural sector—to run different future production scenarios, and agricultural trade regimes out to 2050, and assess changes in related environmental indicators. Results indicate that further trade liberalization is crucial for improving food security globally, but that it would also lead to more environmental pressures in some regions across Latin America. Contrasting land expansion versus more intensified agriculture shows that productivity improvements are generally superior to agricultural land expansion, from an economic and environmental point of view. Finally, our analysis shows that there are trade-offs between environmental and food security goals for all agricultural development paths.

Tracing environmental and cultural changes throughout the Gran Dolina TD10 Middle Pleistocene sequence (Atapuerca, Burgos, Spain)

The well-known eponym El Sidrón has a very special history. It started with the development of a karstic system between two types of rock (sandstone and Neogene conglomerates) as a result of the flow of a small stream. It continued with the use of the cave as a refuge and a hiding place during the Spanish Civil War and the aftermath and with the presence of some endemic species of bats and cave insects

Growth rate and TRI5 gene expression profiles of Fusarium equiseti strains isolated from Spanish cereals cultivated on wheat and barley media at different environmental conditions

Fusarium equiseti is a toxigenic species that often contaminates ce real crops from diverse climatic regions such as Northern and Southern Europe. Previous results suggested the existence of two distinct populations within this species with differences in toxin pro file which largely corresponded to North and South Europe (Spain). In this work, growth rate profiles of 4 F. equiseti strains isolated from different cereals and distinct Spanish regions were determined on wheat and barley based media at a range of temperatures (15, 20, 25, 30, 35 and 40 °C) and water potentialregimens(−0.7,−2.8,−7.0,and −9.8MPa,correspondingto 0.99,0.98,0.95 and 0.93aw values).Growth was observed at all temperatures except at 40 °C, and at all the solute potential values except at−9.8 MPa when combined with 15 °C. Optimal growth was observed at 20– 30 °C and −0.7/−2.8 MPa. The effect of these factors on trichothecene biosynthesis was examined on a F. equiseti strain using a newly developed real time RT-PCR protocol to quantify TRI5 gene expression at 15, 25 and 35 °C and −0.7, −2.8, − 7.0 and −9.8 MPa on wheat and barley based media. Induction of TRI5 expression was detected between 25 and 35 °C and −0.7 and − 2.8 MPa, with maximum values at 35 °C and −2.8 MPa being higher in barley than in wheat medium. These results appeared to be consistent with a population well adapted to the present climatic conditions and predicted scenarios for Southern Europe and suggested some differences depending on the cereal considered. These are also discussed in relation to other Fusarium species co-occurring in cereals grown in this region and to their significance for prediction and control strategies of toxigenic risk in future scenarios of climate change for this region.

Environmental impact indicators estimation in European rural devlopment programs. Limitations of evaluators and financial institutions? Expectatios

The European Commission established Mid-term evaluation for the period 2007-2013 on Rural Development Programs as part of a continuous evaluation system. Mid-term evaluations are important for the Commission because they help measuring the success of a program, as well as giving advice and pointing out good practices for the current and consecutive programming periods. One of the main elements used to achieve these objectives is the impact indicators estimation of the program. This paper will focus on how impact indicators estimation is done for just the environmental indicators. To do this the 88 Mid-term evaluations of Rural Development Programs for 2007-2013 period, were analyzed. This study shows how far the actual methodologies to obtain impact indicators? values are from what the European Commission expects when demanding this task to be done.

Multiresidue Analysis of Insecticides and Other Selected Environmental Contaminants in Poultry Manure by Gas Chromatography/Mass Spectrometry

An analytical method was developed for the simultaneous determination in poultry manure of 41 organic contaminants belonging to different chemical classes: pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and polybrominated diphenyl ethers. Poultry manure was extracted with a modified QuEChERS method, and the extracts were analyzed by isotope dilution GC/MS. Recovery of these contaminants from samples spiked at levels ranging from 25 to 100 ng/g was satisfactory for all the compounds. The developed procedure provided LODs from 0.8 to 9.6 ng/g. The analysis of poultry manure samples collected on different farms confirmed the presence of some of the studied contaminants. Pyrethroids and polycyclic aromatic hydrocarbons were the main contaminants detected.
