The temporal evolution of the electrical signal generated by Pinus halepensis was measured in a sample of 15 trees. Weekly experiments were carried out during a long-term campaign lasting over a year, while trials with a high frequency of measurements were also performed during several days. In the latter case, day-night oscillations of the electrical magnitudes were observed. Additionally, punctual meteorological events such as rainfall and electrical storms affect the electrical signal as well. The measured electrical intensity grows exponentially with the voltage. In fact, no electrical intensity that exceeds the threshold of 0.01 μA is gathered when voltage values are lower than 0.6 V. In general, higher electrical signals were gathered during the rainy seasons with moderate temperatures; while very low signals, including few measures of zero intensity, were obtained during the most stressful periods over the year, mainly by mid-summer. There is a strong correlation between the rainfall and the electrical signal. The rain-intensity correlation, together with sustained intensity values during the reproductive period in spring, suggests that this electrical magnitude could be an indicator of the physiological state of the tree and thus used for in situ and minimally invasive forest monitoring.

Forest management is an untapped tool, yet to realize its full potential to fight against climate change. The capability of forests to act as carbon sinks makes them a key resource to reduce CO2 concentration in the atmosphere. However, carbon which has been fixed can be suddenly emitted again as a consequence of disturbances such as pests or wildfires. Mediterranean plant phenology, climatic conditions, and the accumulation of fuel biomass due to abandonment of traditional forest uses generate a scenario prone to large wildfires and consequently large greenhouse gases (GHG) emissions. The abandonment could be offset by considering the economic value of forest ecosystem services, principally carbon fixation. Nevertheless, currently existing forest carbon markets consider only anthropogenic fixation based on a business as usual scenario without disturbances that cannot be applied to Mediterranean forest reality. Thus, a methodology to monetize carbon fixed has been developed and applied. A range between 55.5 and 250 million € produced by the monetization of 16.5 million potential carbon credits has been obtained based on anthropogenic avoided emissions produced over a 10 year-period. Thereby, the potential for offsetting emissions of the pilot region was between 1.2% and 5.6% of total diffuse GHG emissions. Consequently, sustainable forest management represents an important opportunity to combat climate change, taking advantage of the margin of improvement that the Mediterranean forests currently have to avoid GHG emissions through forest fire prevention silviculture.

Nowadays, about 55% of the world population lives in cities and this is foreseen to increase to 68% by 2050. The urban activities of such a large number of people in relatively small spaces makes the air quality levels in the cities can harmful to human health. For this reason, the European Union (EU) establishes a regulatory framework to control and improve air quality levels in cities (Directive 2008/50/EC) by defining a number of fixed stations and other requirements. The aim of this work is to evaluate the air quality reported by the official fixed stations with the installation of complementary mobile network of air quality based on passive dosimetry of NO2 measurement during the period 2017-2019. In this study, Valencia (Spain) is selected as a representative European city with seven fixed stations and a network of 424 passive dosimetry sensors distributed throughout the city. In addition, an index of impact of pollutant on population (IIPP) is developed to optimize the location of air quality stations among neighbourhoods across the city based on the level of pollution measured by mobile sensors and the population directly affected. The results obtained show that 43.7% of mobile sensors in Valencia exceeded the limit value established by the EU Directive as well as by the World Health Organization (WHO) during the assessment period. This reflects that the air quality levels offered by the fixed stations are neither representative nor reliable for the air quality monitoring of the city. Thus, fixed stations currently operating do not provide reliable information on the areas of the city where the majority of the population breathes air with the highest level of pollution. Specifically, the results show that 34.6% of citizens live in areas with an average annual value above the limit recommended for the protection of human health.

Sustainable cities will only be possible with effective local measures tackling Greenhouse Gas (GHG) emissions. Transport and mobility represent the main sources of these emissions, particularly in urban settings. National and local public administrations need accurate and more responsive tools to quantify GHG emissions. Digitisation and ICTs are key elements in the development of such tools, which, additionally, have to be based on robust methodologies validated by the scientific community. This research presents a bottom-up methodology for the quantification of road traffic's GHG emissions with higher levels of immediacy and spatial resolution when compared to other already existing methods. The methodology uses data from the urban traffic control and monitoring systems as a baseline to calculate emissions. A pilot test has been conducted in Valencia city (Spain). Its results show a highly detailed picture of GHG emission in the city with high temporal (hour) and space (street) resolutions. The emission patterns reflect the dynamics of the city and its citizenship mobility. Since the tools developed for the pilot test can be adapted to other cities, public decision-makers could benefit from a precise diagnosis system based on traffic data to offer and evaluate solutions to reduce road transport GHG emissions.

In this work, we reconstructed the absorption spectrum of different Synechocystis sp. PCC 6803 optical strains by summing the computed signature of all pigments present in this organism. To do so, modifications to in vitro pigment spectra were first required: namely wavelength shift, curve smoothing, and the package effect calculation derived from high pigment densities were applied. As a result, we outlined a plausible shape for the in vivo absorption spectrum of each chromophore. These are flatter and slightly broader in physiological conditions yet the mean weight-specific absorption coefficient remains identical to the in vitro conditions. Moreover, we give an estimate of all pigment concentrations without applying spectrophotometric correlations, which are often prone to error. The computed cell spectrum reproduces in an accurate manner the experimental spectrum for all the studied wavelengths in the wild-type, Olive, and PAL strain. The gathered pigment concentrations are in agreement with reported values in literature. Moreover, different illumination set-ups were evaluated to calculate the mean absorption cross-section of each chromophore. Finally, a qualitative estimate of light-limited cellular growth at each wavelength is given. This investigation describes a novel way to approach the cell absorption spectrum and shows all its inherent potential for photosynthesis research.

Economic profitability of harvested softwood in Southwestern Europe is limited for low quality logs. Some social and environmental consequences of low incomes of rural activities are rural depopulation and accumulation of biomass in unmanaged forests. The energy efficiency of buildings could be improved as construction material employing local bioresources that are currently used to manufacture products of low added value. Here, the IMIP project (Innovative Eco-Construction System Based on Interlocking Modular Insulation Wood & Cork-Based Panels) aimed to support the change towards a low carbon economy using bioproducts (pinewood and cork) for smart, sustainable, and inclusive growth with a special focus on the public construction sector is presented. The main objective of the IMIP project is to design, validate and implement an innovative ecological construction system based on natural biological materials to improve energy efficiency in public buildings from the construction, use and demolition phases. The project also develops a tool to professionals from the construction sector (architects and engineers) and researchers to assess the carbon footprint of buildings. The products of the project have the ambition to improve the economic, social and environmental situation of rural areas of Southwestern Europe.

Electric potential differences in living plants are explained by theories based on sap flow. In order to acquire more advanced knowledge about the spatial distribution of these electric potential measures in trees, this research aims to analyze electrical signals in a population of Aleppo pines (Pinus halepensis Mill.) in a representative Mediterranean forest ecosystem. The specific research objective is to assess some of the most significant factors that influence the distribution pattern of those electric signals: tree age, measurement type and electrode placement. The research has been conducted in representative forest stands, obtaining measurements of different representative trees. After a statistical evaluation of the obtained results, the main conclusions of our research are:

Buildings have become a key source of greenhouse gas (GHG) emissions due to the consumption of primary energy, especially when used to achieve thermal comfort conditions. In addition, buildings play a key role for adapting societies to climate change by achieving more energy efficiency. Therefore, buildings have become a key sector to tackle climate change at the local level. However, public decision-makers do not have tools with enough spatial resolution to prioritise and focus the available resources and efforts in an efficient manner. The objective of the research is to develop an innovative methodology based on a geographic information system (GIS) for mapping primary energy consumption and GHG emissions in buildings in cities according to energy efficiency certificates. The developed methodology has been tested in a representative medium-sized city in Spain, obtaining an accurate analysis that shows 32,000 t of CO2 emissions due to primary energy consumption of 140 GWh in residential buildings with high spatial resolution at single building level. The obtained results demonstrate that the majority of residential buildings have low levels of energy efficiency and emit an average of 45 kg CO2/m2. Compared to the national average in Spain, this obtained value is on the average, while it is slightly better at the regional level. Furthermore, the results obtained demonstrate that the developed methodology is able to directly identify city districts with highest potential for improving energy efficiency and reducing GHG emissions. Additionally, a data model adapted to the INSPIRE regulation has been developed in order to ensure interoperability and European-wide application. All these results have allowed the local authorities to better define local strategies towards a low-carbon economy and energy transition. In conclusion, public decision-makers will be supported with an innovative and user-friendly GIS-based methodology to better define local strategies towards a low-carbon economy and energy transition in a more efficient and transparent way based on metrics of high spatial resolution and accuracy.

The objective of this research is to analyse the feasibility of reusing the fly ash waste, which is produced in biomass plants, during the production of renewable energy, for controlling phosphorus contamination in the wastewater being processed in sewage treatment plants. The research examines the efficiency of using different types of ash, obtained from representative biomass materials after combustion in an energy plant (paulownia wood, wheat straw and barley straw), in removing phosphorus from water. The ashes were respectively mixed with synthetic water, rich in phosphorus; then, using batch experiments, the effects that the pre-treatment of ash, adsorbent dosage, contact time and temperature had on the adsorption process were studied. The main results show that phosphorus adsorption by the tested ashes augments as temperature increases. Similarly, the adsorbed amount of phosphorus increases by increasing the dose of the adsorbent. In addition, the adsorption of phosphorus by these three materials has been described well by the Langmuir isotherm equation. It has been found that the removal process of phosphorus was endothermic. Finally, this study concludes that waste ash from biomass plants can be used to remove phosphorus from wastewater in sewage treatment plants.

Continuous phosphorus discharges in bodies of water, generated by human activities such as agriculture, domestic effluences or wastewater from industrial processes, produce contaminated water and eutrophication. For this reason, efficient and low-cost systems that can remove phosphorus from contaminated water are necessary. In addition, it is important to generate renewable energy such as the energy produced in biomass power plants, taking advantage of the available biomass waste in each place. When producing this renewable energy, the resulting ash is a residue that can be used for phosphorus removal by adsorption processes. Moreover, according to the concept of circular economy, the ash waste generated in this bio energy process should be reduced as much as possible. One of the advantages of this research being that surplus phosphorus-laden ash can be reused as fertilizer in agricultural fields. Considering this, the efficiency of reed ash (Phragmites australis) has been analysed in batch experiments, as well as the effect of several parameters on the removal of phosphate such as contact time, phosphate-ash ratio, ash dose and temperature. Significant results obtained show that reed ash can be used to improve water quality.

In this contribution, we analyze the results of a number of thermal response test (TRT) experiments performed during several years at the same location at our university campus in Valencia (Spain), a permeable saturated soil area with possible groundwater flow conditions. A combination of different heat injection rates, TRT operation times of up to 32 days, and various methods for parameter estimation of ground thermal properties have been applied to study their influence on the result and accuracy of TRTs. Our main objective has been to experimentally quantify the influence of groundwater flow heat advection using moving infinite and finite line-source theories, as well as to analyze the influence of factors such as test duration, sensor accuracy, and external thermal influences. We have shown that the traditionally used infinite and finite line-source models, as well as the moving line-source models, can accurately represent experimental temperature evolution, but that there are many caveats regarding the significance parameters extracted and its reproducibility and stability. These features can be improved if data from the first test days are disregarded for the analysis, obtaining a much faster convergence to the definitive soil parameter estimates, including the effective Péclet number that represents groundwater flow in our particular case.

Acting locally is essential to start working to limit the climate change impact and to reduce substantially and constantly GHG emissions. Indeed, the lack of GHG emissions quantification tools in real time and at local level, makes it difficult for public decision-makers to focus efforts and resources efficiently against climate change. In this paper, we propose an agent-based approach applied to an integral management tool to quantify GHG emissions in an accurate and up to date manner. The management tool ensures automatic and reliable management of large volumes of information minimising human interventions. The integral management tool is being tested in a pilot action in a medium-sized city in Eastern Spain (Llíria) to convert it into an innovative and sustainable Smart City.

Las plantaciones de rotación corta desempeñan un papel importante como fuente biomásica energética sostenible que puede aumentar la seguridad del suministro, la generación de ingresos en comunidades rurales locales y disminuir la dependencia energética de combustibles fósiles. En este sentido, las plantaciones de rotación corta han sido ampliamente reconocidas, lo que hace necesario aumentar las alternativas de fuentes biomásicas disponibles para su uso energético. El objetivo de este estudio fue cuantificar la biomasa leñosa y el potencial energético de la especie arbórea paulonia (Paulownia spp.) de un año de edad en condiciones mediterráneas. Se seleccionaron parcelas de prueba en la Comunidad Valenciana (España oriental) para desarrollar un modelo predictivo de cuantificación de biomasa y su potencial energético, en dos tipos de parcelas según densidad y existencia de riego (P1 y P2), siendo el promedio efectivo de biomasa por hectárea (el fuste es hueco en su sección medular en un 19,2%) en P1 y P2 de 27,3 t ha-1 a 47,6 t ha-1, respectivamente. En cuanto al potencial energético, los ensayos de laboratorio muestran que paulonia posee un poder calorífico de 17,8 MJ kg-1, su energía potencial en P1 es de 207 MJ árbol-1y 247 GJ ha-1 y mayor en P2 con 349 MJ árbol-1 y 274 GJ ha-1. Teniendo en cuenta el rápido crecimiento de esta especie y su alto potencial energético, debería considerarse como una materia prima válida para su uso en energía térmica a corto plazo en zonas mediterráneas.

Termite resistance of thermally-treated ash (Fraxinus excelsior L) and European beech (Fagus sylvatica L) against subterranean termites (Reticulitermes banyulensis) was evaluated. A laboratory no-choice feeding test following the standard EN 177 was performed to assess the efficacy of this thermo-modification against subterranean termites in the Mediterranean area. After 8 weeks period of exposure, results showed that durability against termites was slightly improved for thermally-treated beech wood, which was classified as moderately durable. However, in case of thermally-treated ash wood, samples were highly biodegraded by termites, revealing no increase in their durability and being classified as non durable.

This research was based on three species: Citrus sinensis (orange), Olea europaea (olive), and Prunus amygdalus (almond). The biomass was determined for a complete tree without roots, but including stem, branches, and canopy or crown. The obtained results demonstrate that the stem volume is slightly higher for almond trees (0.035 m3/tree) than for olive trees (0.027 m3/tree). In comparison, the average stem volume of orange trees is lower (0.006 m3/tree). On the other hand, the total biomass volume including canopy branches is similar in all three species: 0.043 m3/tree for orange tree, 0.066 m3/tree for olive tree, and 0.040 m3/tree for almond tree. The new practical quantification model for these Mediterranean agricultural crops is based on total biomass calculations normally used in forestry stands. So, the obtained values were used to develop models for biomass of the stem, branches, and canopy, relating them with the diameter and volume stem. The regression analysis shows a significant correlation with minimized estimation errors. This allows a practical use of this model in biomass calculation in standing trees, both for total tree biomass and also for pruning material.

Considering the decay risk of wood structures in temperate regions and the need to implement environmentally sound and healthy safe integrated pest management strategies, the main objective of this research was to detect xylophagous insects (especially termites) at an early stage as well as to relate the wood conditions in buildings (moisture content and temperature) to the infestation risk of the main wood-rotting fungi. To do this, an advanced sensor was developed. It sends a wireless alarm with the indication of termite activity inside the wood or with the warning signal that the conditions in the wood make it vulnerable to fungal settlement. After investigating the main detection parameters and testing different prototypes under varying laboratory conditions, a final sensor was developed for use in real conditions. Furthermore, a wireless network of these biodegradation sensors was developed and installed in three representative buildings for their automatic monitoring, forming an integral alarm system for wood degradation activity supported by an advanced remote sensing management.

Die Untersuchungen das Kernholzes von Prosopis kuntzei ergaben eine sehr hohe Dauerhaftigkeit gegenüber dem Basidiomyceten Trametes versicolor und der subterranen Termitenart Reticulitermes banyulensis. Im Erdkontakt wird das Holz als mëßig dauerhaft eingestuft. Die niedrigen Masseverluste gegenüber Moderfäule werden neben dem Holzabbau auch Auswaschungsprozessen zugeschrieben. The heartwood of Prosopis kuntzei showed excellent resistance against the basidiomycete Trametes versicolor and the subterranean termite species Reticulitermes banyulensis. The wood was classified as moderately durable in soil contact. The low mass losses are presumptively caused by leaching effects in addition to soft rot decay.
