Landslide risk in Haiti and land management in Port au Prince

This thesis aims to identify landslide risk zones in Haiti as a whole (regional scale) and Port au Prince specifically (local scale) and to evaluate how this landslide risk can affect them, especially to Port au Prince, in order to elaborate recommendations in priority zones of the city. Landslide risk priority zones are marked in order to apply land management recommendations supported in the Haitian land tenure to reduce, mitigate or delete at maximum the possible damages that these zones can suffer in the future due to landslides. These recommendations are collected in order to stakeholders decide which of them are the best options for each priority zone. Different types of maps are generated in order to locate all landslide risk zones and priority zones.

The impact of sustainable construction and knowledge management on sustainability goals. A review of the venezuelan renewable energy sector

The recognition of the relevance of energy, especially of the renewable energies generated by the sun, water, wind, tides, modern biomass or thermal is growing significantly in the global society based on the possibility it has to improve societies′ quality of life, to support poverty reduction and sustainable development. Renewable energy, and mainly the energy generated by large hydropower generation projects that supply most of the renewable energy consumed by developing countries, requires many technical, legal, financial and social complex processes sustained by innovations and valuable knowledge. Besides these efforts, renewable energy requires a solid infrastructure to generate and distribute the energy resources needed to solve the basic needs of society. This demands a proper construction performance to deliver the energy projects planned according to specifications and respecting environmental and social concerns, which implies the observance of sustainable construction guidelines. But construction projects are complex and demanding and frequently face time and cost overruns that may cause negative impacts on the initial planning and thus on society. The renewable energy issue and the large renewable energy power generation and distribution projects are particularly significant for developing countries and for Latin America in particular, as this region concentrates an important hydropower potential and installed capacity. Using as references the performance of Venezuelan large hydropower generation projects and the Guri dam construction, this research evaluates the tight relationship existing between sustainable construction and knowledge management and their impact to achieve sustainability goals. The knowledge management processes are proposed as a basic strategy to allow learning from successes and failures obtained in previous projects and transform the enhancement opportunites into actions to improve the performance of the renewable energy power generation and distribution projects.

People and Facility Management. The team: the main asset of any management

From the moment we enter a large office building until we leave it, we receive a lot of attentions served by the management of services to the user. However, it is usually quite inappreciable the work that is being developed to keep things running smoothly.The services provided in a building are carried out by people. However, we often tend to forget these people when we talk about the tasks that make that a building operates properly 24 hours a day, 365 days a year.But, for example, what would happen if one day the service provided by the reception in a large building did not function as it should? What would it be like if one day the person performing the service of maintenance of the building's cleaning were not at his post? How would the working day develop if there were not a correct air handling system?People are the foundation of the proper functioning of a building. The work of the Facilities Manager and the Facility Management is the management of their functions: the responsible management of the team.

The potential of organic fertilizers and water management to reduce N2O emissions in Mediterranean climate cropping systems. A review.

Environmental problems related to the use of synthetic fertilizers and to organic waste management have led to increased interest in the use of organic materials as an alternative source of nutrients for crops, but this is also associated with N2O emissions. There has been an increasing amount of research into the effects of using different types of fertilization on N2O emissions under Mediterranean climatic conditions, but the findings have sometimes been rather contradictory. Available information also suggests that water management could exert a high influence on N2O emissions. In this context, we have reviewed the current scientific knowledge, including an analysis of the effect of fertilizer type and water management on direct N2O emissions. A meta-analysis of compliant reviewed experiments revealed significantly lower N2O emissions for organic as opposed to synthetic fertilizers (23% reduction). When organic materials were segregated in solid and liquid, only solid organic fertilizer emissions were significantly lower than those of synthetic fertilizers (28% reduction in cumulative emissions). The EF is similar to the IPCC factor in conventionally irrigated systems (0.98% N2O-N N applied−1), but one order of magnitude lower in rainfed systems (0.08%). Drip irrigation produces intermediate emission levels (0.66%). Differences are driven by Mediterranean agro-climatic characteristics, which include low soil organic matter (SOM) content and a distinctive rainfall and temperature pattern. Interactions between environmental and management factors and the microbial processes involved in N2O emissions are discussed in detail. Indirect emissions have not been fully accounted for, but when organic fertilizers are applied at similar N rates to synthetic fertilizers, they generally make smaller contributions to the leached NO3− pool. The most promising practices for reducing N2O through organic fertilization include: (i) minimizing water applications; (ii) minimizing bare soil; (iii) improving waste management; and (iv) tightening N cycling through N immobilization. The mitigation potential may be limited by: (i) residual effect; (ii) the long-term effects of fertilizers on SOM; (iii) lower yield-scaled performance; and (iv) total N availability from organic sources. Knowledge gaps identified in the review included: (i) insufficient sampling periods; (ii) high background emissions; (iii) the need to provide N2O EF and yield-scaled EF; (iv) the need for more research on specific cropping systems; and (v) the need for full GHG balances. In conclusion, the available information suggests a potential of organic fertilizers and water-saving practices to mitigate N2O emissions under Mediterranean climatic conditions, although further research is needed before it can be regarded as fully proven, understood and developed.

A semantic middleware architecture focused on data and heterogeneity management within the Smart Grid

There is an increasing tendency of turning the current power grid, essentially unaware of variations in electricity demand and scattered energy sources, into something capable of bringing a degree of intelligence by using tools strongly related to information and communication technologies, thus turning into the so-called Smart Grid. In fact, it could be considered that the Smart Grid is an extensive smart system that spreads throughout any area where power is required, providing a significant optimization in energy generation, storage and consumption. However, the information that must be treated to accomplish these tasks is challenging both in terms of complexity (semantic features, distributed systems, suitable hardware) and quantity (consumption data, generation data, forecasting functionalities, service reporting), since the different energy beneficiaries are prone to be heterogeneous, as the nature of their own activities is. This paper presents a proposal on how to deal with these issues by using a semantic middleware architecture that integrates different components focused on specific tasks, and how it is used to handle information at every level and satisfy end user requests.

Exploring the link between sustainability reporting and sustainability management: a conceptual framework.

Sustainability managementand Sustainability Reporting (SR) practices have dramatically increased during the last two decades, raising important questions about the relationship between internal practices and external communication. Previous literature on SR has almost exclusively highlighted the role of institutional and stakeholder pressures in driving its adoption. However, as surveys among reporters also identify internal benefits of SR, its full role for company-level sustainability management remains unclear. In order to address this question, we develop a framework accounting for four SR configurations, stemming from different levels of relative importance of external and internal motives for SR. A multiple case study involving four large Spanish companies serves to illustrate the framework and to identify company-level factors that act both as enablers and barriers of SR internal relevance. We conclude that motivations for SR, along with such internal factors, decisively influence its contribution to sustainability management.

El programa ERHIN y la gestión de embalses en áreas con alta precipitación nival = The ERHIN programme and reservoir management in areas of high nival precipitation

El programa de Evaluación Recursos Hídricos procedentes de la Innivación (ERHIN) ha desarrollado un modelo hidrológico con subrutinas que contemplan el proceso de acumulación/fusión de nieve que permite el seguimiento del manto de nieve y su fusión , esencial para la previsión de avenidas en embalses cuyas cuencas vertientes recogen altos porcentajes de precipitación solida. En determinados sectores del territorio español (Pirineos, Cordilleras Cantábrica e Ibérica, Sistema Central y Sierra Nevada) la precipitación nival alcanza valores significativos durante el invierno, que conducen a espesores de nieve persistentes en las cuencas alimentadoras de numerosos embalses y a la fusión rápida de esta nieve en períodos cortos de tiempo, directamente relacionados con la elevación de la isoterma de cero grados en primavera. Estos procesos condicionan la gestión de los mencionados embalses.

Reproductive and nutritional management on ovarian response and embryo quality on rabbit does

Rabbit does in modern rabbitries are under intensive reproductive rhythms. Females are high milk producers with high energetic expenses due to the extensive overlap between lactation and gestation. This situation leads to a negative energy balance with a mobilization of body fat especially in primiparous rabbit does. Poor body condition and poor health status severely affect the reproductive features (fertility rate and lifespan of the doe as well as ovarian physiology). This paper reviews some reproductive and nutritional approaches used in the last years to improve the reproductive performance of rabbit females, mainly focusing on the influence on ovarian response and embryo quality and with emphasis on epigenetic modifications in pre-implantation embryos and offspring consequences.

Internet of things virtualization and identity management via fiware generic enablers

La iniciativa FIWARE ofrece un conjunto de APIs potentes que proporcionan la base para una innovación rápida y eficiente en el Internet del Futuro. Estas APIs son clave en el desarrollo de aplicaciones que usan tecnologías muy recientes e innovadoras, como el Internet de las cosas o la Gestión de Identidad en módulos de seguridad. Este documento presenta el desarrollo de una aplicación web de FIWARE usando componentes virtualizados en máquinas virtuales. La aplicación web está basada en “la fábrica de chocolate de Willy Wonka” como una implementación metafórica de una aplicación de seguridad e IoT en un entorno industrial. El componente principal es un servidor web en node.js que conecta con varios componentes de FIWARE, conocidos como “Generic Enablers”. La implementación está compuesta por dos módulos principales: el módulo de IoT y el módulo de seguridad. El módulo de IoT gestiona los sensores instalados por Willy Wonka en las salas de fábrica para monitorizar varios parámetros como, por ejemplo, la temperatura, la presión o la ocupación. El módulo de IoT crea y recibe información de contexto de los sensores virtuales. Esta información de contexto es gestionada y almacenada en un componente de FIWARE conocido como Context Broker. El Context Broker está basado en mecanismos de subscripciones que postean los datos de los sensores en la aplicación, en tiempo real y cuando estos cambian. La conexión con el cliente se produce mediante Web Sockets (socket.io). El módulo de seguridad gestiona las cuentas y la información de los usuarios, les autentica en la aplicación usando una cuenta de FIWARE y comprueba la autorización para acceder a distintos recursos. Distintos roles son creados con distintos permisos asignados. Por ejemplo, Willy Wonka puede tener acceso a todos los recursos, mientras que un Oompa Loopa encargado de la sala del chocolate solo deberías de tener acceso a los recursos de su sala. Este módulo está compuesto por tres componentes: el Gestor de Identidades, el PEP Proxy y el PDP AuthZForce. El gestor de identidades almacena las cuentas de FIWARE de los usuarios y permite la autenticación Single Sing On usando el protocolo OAuth2. Tras logearse, los usuarios autenticados reciben un token de autenticación que es usado después por el AuthZForce para comprobar el rol y permiso asociado del usuario. El PEP Proxy actúa como un servidor proxy que redirige las peticiones permitidas y bloquea las no autorizadas.

Laser remote sensing applications (LiDAR) in forest hydrology and the management of river ecosystems.

La utilización de sensores láser desde plataformas aéreas (LiDAR) ofrece nuevas posibilidades en el cartografiado de sistemas fluviales, tanto en áreas densamente cubiertas por vegetación, como en aquellas que presentan una escasa cubierta. La información topográfica de alta resolución que se obtiene a partir de las medidas láser puede ser utilizada en el análisis y estimación de diversas variables hidrológicas, y en el estudio de diferentes componentes del medio fluvial. Entre éstas, cabe citar la vegetación riparia, la morfología fluvial, el régimen hidrológico o el grado de alteración de los ecosistemas debido a las presiones de origen antrópico. La gestión del medio fluvial puede ser mejorada en gran medida gracias a la precisión y fiabilidad de esta información. En muchas ocasiones, el escaso relieve de los valles fluviales y la densa cubierta vegetal que existe en ellos han dificultado la aplicación de otras técnicas de teledetección. Sin embargo, los datos obtenidos mediante altimetría láser son especialmente aconsejables para estos trabajos, mediante análisis numéricos o a través de la simple interpretación de las imágenes obtenidas. Este artículo muestra las posibilidades de uso de los datos LiDAR en hidrología forestal y en la gestión de zonas húmedas, a lo largo de tramos con condiciones climáticas bien diferenciadas. En todas ellas, se comparan los resultados obtenidos mediante la aplicación de distinto software, con el fin de mostrar la mejor metodología de tratamiento de la información láser. Asimismo, se muestra la diferencia con otras técnicas de teledetección, y se muestra la fácil integración de los datos LiDAR con otras herramientas y metodologías de estudio de las variables citadas.
