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.

Forest fires are increasing their recurrence, intensity and scale in Portugal, increasing also the vulnerability of this region of Southwestern Europe to the impacts of the climate change. In Portugal, several studies have been focusing the dynamic of cork oak forest after fires from tree level to landscape level. However few information is available about the impact of wildfires in the soil quality, namely C stock, and its evolution. This component of the ecosystem and the evolution of its characteristics can be related with the dynamics of the landscape in the post-fire period and its knowledge can help in the management and rehabilitation of plant-soil system.

Serra do Caldeirão is located in Algarve region (S of Portugal). The soils are classified as Leptosols with low fertility. The landscape is characterized by cork oak forests with shrub cover which is dominated by Cistus species. To assess the distribution of total organic C in the study area, several soil sampling were intersected, on two sampling dates (2012 and 2013), with the vector information of the burned area in 2004. This information was intended to assess the temporal evolution of C concentration, depending on its location in a burnt or non-burnt area.

In general, the burnt areas showed greater variability of C concentrations in soils collected in both the years, with maximum values ​​of 33.0 g/kg for 2012 and 36.5 g/kg for 2013. These maximum values ​​exceed those obtained for soils in non-burnt areas. Despite of this scenario, and independently of the year, no statistically significant differences were found in the C concentrations of the burnt plots and the control plots. For other chemical characteristics (e.g. nutrients), the variations depended on the area. Implementation of post-fire recovery measures and forest management of the areas can justify this variation.

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.

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.
