Riassunto
Summary
Water
is a unique natural resource, renewable but at the same time limited. For
years, the use of water resources has been done, as if it was unlimited,
without considering the ecological and geological balances connected.
Forests play a significant role of protection, both for the prevention of
erosion and loss of soil, and for the protection of drinkable water. These,
covering approximately 1/3 of the area, have a strong importance in
relation to water resource considering that it represent the main source
for the production, storage and the collection of drinking water necessary
for the people’s needs. The availability and quality of water are
characteristics strongly influenced by forests, and thereby depending on a
correct forest management. The role of sylviculture in the protection of
water resources must now be integrated in the broader panorama of the
sustainability of forest management, directed towards the preservation and
the raise of the effectiveness of forest systems on water regulation, the
improvement of water availability and the non alteration of processes that
control water quality, the contrast of degradation phenomena and soil
erosion processes that represent the more significant indication of
desertification. Integrated management of water resources, reduction of
catastrophic phenomena, fight against desertification, represent thematic
for which, both at international and national level, exists an renewed
awareness as recently shown by the Fifth Ministerial Conference on the
Protection of Forests in Europe held in
