Interaction between water and forest – challenge to water policies and forest management

05.01.2009
Incorporating results from forest hydrology studies in water policies can help avoid uncertainty and confusion caused by the current difficulties in transferring research findings to different countries and regions, varying forest types and species and diverse forest management regimes.

In addition, institutional mechanisms to enhance synergies in forests and water administrations are needed at national and regional levels.

These key messages to the decision makers were formed during the international conference “Water and Forests: a convenient truth?” held in October 2008. The conference gathered together renowned scientists to addressed the topic not only at a global level, but also highlighting the situation in the Mediterranean area.

The conference agreed that it is clear that forests are linked to water yield. Forests use more water than shorter types of vegetation caused by their higher evaporation. Water use efficiency differs between forest species; and soil water availability fluctuates at each stand. Canopies protect the ground from runoff which also means higher interception. Root systems influence the groundwater recharge. Consequently, forest management practices should be adjusted to reach desired impacts on water by using a mix of different tree species and of varying ages, or by designing forest structure and open areas (e.g. from harvesting). Follow up of such measures is required as it is essential to determine the influences of forest management actions in water at each stand.

One of the other main findings shows that global climate models predict marked changes in seasonal snow- and rainfall with more uncertainties than in temperatures. Also, they forecast a significant decrease in rainfall in the Mediterranean basin and an increase of rainfall during in winters in Central and Northern Europe.

Therefore, when designing large-scale forest plantations for C sequestration, water shortage should not be accentuated. Shade provided by riparian forests may help reduce thermal stress to aquatic life as climate warming intensifies.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
