  • Climate change is particularly relevant because it is expected to alter not only the natu- ral environment as a result of flooding or drought but also the urban environment as a result of changes in land use. Only the future will tell to what degree these factors will affect the risk of pest-related dis- eases. Still, the conclusions drawn by this report will help and support national govern- ments to understand better the public health relevance of urban pests and to be able to prepare the ground for increased technical capacity and ability for action.

  • Climate change (CC) is one of the most significant challenges facing human beings in the 21st century. CC will seriously affect lives, production and environment worldwide. It also leads to the increasing temperature and one of its consequences is sea level rise, resulting in unpredicted changes of the river flow. This may cause more severe floods, serious drought and water shortage, further to continent of the salinity intrusions and negatively effect on the human’s lives, socio-economic development.

  • Over the next 100 years, climate models suggest that warmer temperatures will very likely lead to greater climate variability and an increase in the risk of hydrologic extremes, i.e., floods and droughts. Perhaps the most significant and likely impact is a change in the timing of runoff in watersheds with large amounts of winter snowfall as higher temperatures lead to an increase in the ratio of rain to snow, faster snowmelt runoff, and earlier loss of snow.
