... Preserving biodiversity is directly linked to the problem of climate change. According to the climate change scenarios (Alexandrov, 2007;Raev et al. 2015;Tsenov et al. 2015) the climate in Bulgaria will become hotter and drier in near future. The most negative impacts are expected to affect forests situated from 0 to 800 m a.s.l. ...

... Decreases of the water table, reduction of water resources, reduced spring discharge and reduced river flows have been documented in many parts of the world over the last decades (Collins, 2008;Aguilera and Murillo, 2009;Hidalgo et al., 2009;Piao et al., 2010;Jiménez Cisneros et al., 2014). Concerns over the negative impacts of climate change on groundwater and water resources specifically in Europe have been raised in several studies (Brouyère et al., 2004;Yustres et al., 2013;Cen cur Curk et al., 2014;Kløve et al., 2014;Pr av alie, 2014;Pr av alie et al., 2014). Further contributing to negative impacts of climate change on groundwater quality are increases of groundwater temperature (Taylor and Stefan, 2009;Kløve et al., 2014) and subsequent changes to chemical reactions that occur in soils (Figura et al., 2011;Haldorsen et al., 2012;Kløve et al., 2012). ...

... In recent decades, global climate change has led to major differences in temperature and precipitation records. These differences were found to have a direct negative influence on water resources and environmental elements at a global level [2,3]. Due to the lack of knowledge of environmental changes, the inadequate management of natural resources and inefficient strategies, the impact of climate change on water resources has been greater than was expected, contributing to limited resources and affecting conservation and sustainability [4][5][6]. ...
