Many satellite-based methods for fire detection and monitoring have been developed to exploit data acquired by sensors. Their relatively low temporal resolution (hours) is, however, decidedly not adequate for detecting short-living events or fires characterised by a marked diurnal cycle and rapid evolution times.
The shortcomings of wildfire spread modeling systems and the widespread use of their outcomes in fire management decisions render the evaluation of fire simulation results crucial for model calibration and improvement. This study proposes an exploratory evaluation framework of fire growth simulations using satellite active fire data.
The extent of fires, their periodicity and their impact on terrestrial communities is always a concern. Wildfires play an important role in shaping landscapes and as a source of CO2 and particulate matter. Modeling the spatial variability of wildfire extent is an important subject in order to understand and to predict future trends on their effect in landscape changes.
Insect pests are a major threat to many forests worldwide, from boreal to tropical forest ecosystems. Some pests exhibit periodical outbreaks, after which their populations often crash as a result of natural biological control. In this study, authors assessed the performance of aerial spraying of insecticides on pine woodland stands to control pine processionary moth Thaumetopoea pityocampa (PPM) outbreaks in southern Spain.
Protected areas (PAs) are the main instrument for biodiversity conservation, which has triggered the development of numerous indicators and assessments on their coverage, performance and efficiency. The connectivity of the PA networks at a global scale has however been much less explored; previous studies have either focused on particular regions of the world or have only considered some types of PAs.
Since many years, there were tries to value a subproduct of almond industry, which constitutes 75% of total almond biomass volume. Crashed and filtered almond shells, that we talk in this post about, surprisingly have similar characteristics to wood pellets. However, the biggest advantage of this energy carrier is undoubtedly its price, which is much more attractive, than its derived from wood competitor.
The European Sawlog Price Index reached its lowest level in six years in the 3Q/16 because of lower lumber demand and reduced prices in both domestic and export markets, reports the Wood Resource Quarterly Declining demand and prices for softwood lumber, together with reduced log trade have resulted in lower sawlog prices in Europe over the past two years with the ESPI sawlog prices index reaching its lowest point since 2010, according to the Wood Resource Quarterly.
Forest engineering in Spain has a long tradition and active presence in the engineering field. It is also one of the first educational institutions that shaped the Spanish technological panorama in the mid nineteenth century. The actual situation of the forest systems in Spain is the result of 166 years of observation, research, education and the application of specific techniques and principles that forest engineers acquired with the successive study plans that were implanted in educational institutions.
In 2015 pellet production capacity in Spain, distributed among 79 plants, was 1,250,000 tonnes, but production did not exceed 475,000, the 38%. It is one of the data obtained from the ENplus day: five years committed to the quality of the wood pellet, celebrated this morning by Avebiom in the Madrid headquarters of Aenor.
