The promotion of the adoption of renewable energies in deprived and remote areas can be considered as an important step towards reduction of threats to the loss of biodiversity through community mobilization. One important outcome is mitigation of the deforestation processes through firewood collection. The aim is achievement of sustainable development of the forest biodiversity, awareness raising and the capacity building for execution of similar projects. The social and economical aspects and the obstacles for execution of such project were investigated and guidelines were prepared to facilitate the promotion of renewable energy in similar small communities

Forested areas can cause positive impacts on ecosystems and water supply for agriculture, electricity generation, industry, and human. On the other hand, large-scale deforestation affects the water and energy budget on a regional and global scale. Considering the importance of this issue, this study evaluates the impact of land use and land cover changes (LULC) on the water cycle components, including precipitation, evapotranspiration, runoff, and hydroclimatic variables such as soil moisture, air temperature, soil temperature, and sensible heat flux in southeastern Australia using an ecosystem model called Integrated Biosphere Simulator (IBIS). For this purpose, a two-year time span with...

Landslide events are among natural hazards with many fatalities and financial losses. Studies demonstrate that natural factors such as rainfall and human activities such as deforestation are important causes of triggering a landslide. In this study, an integrated two-dimensional slope stability model, SSHV-2D, is developed that considers various aspects of hydrological effects and vegetation impacts on the stability of slopes. The rainfall infiltration and water uptake of roots change the water content of the unsaturated zone. The temporal and spatial distribution of water content is estimated in the hydrological unit of the developed model. The vegetation unit of the model considers...
