Cel To identify relations which link inflammability of vegetationexposed to stress conditions and emission of essential oils. Todefine the feasibility of a dedicated sensor based on essentialoils sensing and to establish its characteristics. To providesupport to design and optimize a network of sensors, in order tomonitor an area with the best performance/cost ratio. To assessa "bio-climatic" risk index, combining usual methods and datawith information provided by the sensors, in order to improverisk monitoring.The study will be initiated with field and laboratory experimentsand processing of results to establish relations. In the field,representative areas will be selected in Creete and monitored foressential oil emission and content. Different species will beused, covering all major plants of Mediterranean type ecosystems.Plant essential oil content and emission will be studied asrelated to water stress, air temperature and relative humidity.Water stress will be determined by measuring plant waterpotential and soil moisture content. The contribution ofessential oils to plant flammability will be determined byconducting experiments of ignitability. We will analyse thechemical components of the plant essential oils with gaschromatography and determine the pyric parameters usingcalorimeters.From the results of this first phase, we will define thesensitivity level of the sensor and establish the differentchemicals that can be used to evaluate inflammability. We willthen study the different methods that can be used to senseessential oils, on the basis of most recent developments inchemical sensing. From this study and from the results of fieldand laboratory measurements, we will propose a detection methodwith its characteristics.To establish a method for sensor positioning, we will define a"static risk", based on statistical data from the region tomonitor (weather, fire events), topography and vegetationcoverage, to identify the regions of higher risk and the regionswhere sensor information will be the most pertinent. From thisanalysis, we will propose a strategy to define the best locationsfor sensors and to evaluate how many sensors are needed to coverthe region of interest.For risk monitoring, we will study the bibliography of methodsfor risk assessment and identify the conditions where data fromrisk sensors can improve the estimation. Then, we will propose anew method for risk assessment associating different scales oftime: static, integrated and real-time. Finally, we will studyspatial interpolation methods that can be applied to basic andcombined parameters, in order to build and update a map of riskover the region. We will also propose methods to automate riskassessment with the evolution of the parameters and sensor data.
