Comparison between Willingness-to-Pay expressed by a panel of forestry experts and by a sample of non-expert respondents in a pilot survey conducted …
2005
This work deals with an empirical analysis aiming to check the possibility to substitute a panel of forestry experts for a sample of non-expert respondents in a pilot survey for a CVM study. This methodology in the case study has focussed on the estimate of the economic value associated with the reduction in wood fire risk in a protected area of southern Sicily. The experiment consisted in carrying out two surveys by means of the same questionnaire with an open-ended elicitation question for WTP’s. The first survey was addressed to a sample of 227 “non-expert” respondents, whereas in the second one 15 forest technicians working in Sicily were interviewed in their quality of experts in fores…
‘Back to the Future’—Oak wood-pasture for wildfire prevention in the Mediterranean
2021
In the summer of 2021, enormous wildfires in the Mediterranean eliminated huge areas of mainly coniferous forest, destroyed adjacent settlements and claimed the lives of many people. The fires indicate effects of climate change and expose consequences of rural demographic changes, deficits in regional and touristic development planning and shortcomings in forest policy. This forum article highlights the dimensions of the problem, calls for a paradigm shift and shows solutions. Land abandonment, woody plant encroachment and non-reflective afforestation are leading to increasing amounts of combustible biomass. To prevent disastrous fires in future, fundamental changes in tree species composit…
Impact of Land Cover Change Induced by a Fire Event on the Surface Energy Fluxes Derived from Remote Sensing
2015
Forest fires affect the natural cycle of the vegetation, and the structure and functioning of ecosystems. As a consequence of defoliation and vegetation mortality, surface energy flux patterns can suffer variations. Remote sensing techniques together with surface energy balance modeling offer the opportunity to explore these changes. In this paper we focus on a Mediterranean forest ecosystem. A fire event occurred in 2001 in Almodovar del Pinar (Spain) affecting a pine and shrub area. A two-source energy balance approach was applied to a set of Landsat 5-TM and Landsat 7-EMT+ images to estimate the surface fluxes in the area. Three post-fire periods were analyzed, six, seven, nine, and 11 y…
