Abstract |
| Forest fires are a natural process in many ecosystems. Each has a
regime characteristic fire, that is, a level of frequency, size,
intensity
and certain seasonality and is considered natural and necessary for
maintaining the sustainability and biodiversity species. The
problem of forest fires arises when the balance between what is
considered “natural” and sustainable breaks. Today, it seems that there
is no doubt that we are immersed in a period of climate change
characterized by global warming, which suggests that the current
regime of forest fires is also likely to change due to, among other
things, the close relationship established between climate and
forest fires. The rainfall is also changing, a decrease is observed in
water availability and increasing drought periods, so this change
will not compensate for the temperature increase and enhance the
flammability of forest areas. Have identified a number of factors
related to global change and are linked with the change of regime forest
fires, such as changes in the density and distribution of
human population (involved in increasing the number of ignitions), the
rural abandonment, deforestation and fragmentation of the
landscape, changes in the management of the mountain, the increase of
invasive species and increased carbon dioxide in plants and
ecosystems (involved in increasing the quantity and continuity, i.e.,
availability, made out of fuel). Thus, changes in climate, alone, are
not sufficient to bring about extreme changes in fire regime in the
short or medium term, but the increase is needed and continuity of
fuel (biomass) in a given space. Trying to predict long-term changes in
fire regimes is very difficult and imprecise, since it will depend
on the interactions between influencing factors and their relationship
over time, true modelers fires and shapers of the landscape. |
