Abstract Forests cover approximately one-third of Germany’s territory. They are among the most productive forests in Europe and a position to contribute considerably climate change mitigation. Germany has set national targets for mitigation via measures such as conversion towards mixed climate-adapted forests; stronger control on sustainability imported solid biofuels; an increase forest area; ...

introduction today, climate change issue is one of the main challenges for scientists and due to the critical role of water in human life, the study of climate change impacts on severity and frequency of drought in each region seems to be indispensable (hulme et al., 1999). drought is usually occurred over a period of water shortage owing to less rainfall, high evapotranspiration and pumping a ...

Both climatic and edaphic conditions determine plant distribution, however many species distribution models do not include edaphic variables especially over large geographical extent. Using an exceptional database of vegetation plots (n = 4839) covering an extent of ∼55,000 km2, we tested whether the inclusion of fine scale edaphic variables would improve model predictions of plant distribution...

Climate change is a fundamental challenge for which agriculture is sensitive and vulnerable. The Intergovernmental Panel on Climate Change has identified relevant information as key to enabling appropriate climate adaptation and mitigation action. Information specifically directed to farmers can be found, for example, in specialized farming magazines. While recent studies examine how national n...

Background: Today, with the development of technology, the presence and role of human resources has been highlighted in industrial environments. Hence, the importance of safety culture is growing. Mining is the one of the most dangerous occupations. Therefore, this study was performed to determine the effect of health, safety, and environment management system (HSE-MS) on safety climate in one ...

[1] Climate forcing and climate sensitivity are two key factors in understanding Earth’s climate. There is considerable interest in decreasing our uncertainty in climate sensitivity. This study explores the role of these two factors in climate simulations of the 20th century. It is found that the total anthropogenic forcing for a wide range of climate models differs by a factor of two and that ...

This study described the development of a safety climate instrument for employees at three mini-steel mill locations in the U.S. The instrument was validated by structural equation modeling using AMOS and measured safety climate at a specific “point in time” to assess the safety culture of the industry. The Hall Safety Climate Instrument was developed using a three-construct theoretical framewo...
