HERNANDEZ HOSTALLER, Néstor. PSR indicator for forest fire and network sensors for early detection of forest fires in Costa Rica. Tecnología en Marcha [online]. 2017, vol.30, n.2, pp.48-57. ISSN 0379-3982.


If the OECD gives Costa Rica a chance to enter, the use of modern technology to turn off and control forest fires contributes to strengthening the perception people have of the country and undoubtedly facilitates the income


A forest fire is a fire that expands without any control in a forest region. In Costa Rica, between 1998 and 2006 the forest fires have affected 35428 ha, and in 2007 at least 2468 ha, according to information from CONIFOR (MINAET) [1]. As an immediate effect, this situation contributes to the disappearance of the forest. This reality, in addition to other activities, such as logging and hunting, demand collaboration for the control of these attacks to the forest. Current electronic technologies, applied to environmental protection, offer possible solutions, particularly the use of wireless sensor networks (WSN) for Early Detection of Forest Fires (EDFF). Even though these have not been fully exploited in Costa Rica, there are currently research and development activities aiming at the use of such networks in forest protection.


The advance preparation, or the reaction that a country or region has for facing various problems or environmental disasters affecting sustainable development, can be manifested through indicators PSR (Pressure-State-Response) OECD (Organization for Economic Co-operation and Development), and in the case of wildfire the FFPI indicator (Forest Fire Pressure Index) that relates the forest area burned with the forest area that has not been affected. That means the effect of these fires is reflected in the respective environmental indicators.
