ABSTRACT

 

Climate change is posing very serious challenge and becoming very hazardous problem not only for human beings but also for thousand of species. Rate of global warming is increasing day by day due to several anthropogenic pressures and natural causes also. In this paper an attempt has been made to study the effect of climate change on five (05) major tanks of Bhalki taluka in Bidar district of Karnataka State. Almost all the tanks except one have been constructed before 50 years. Accordingly the present scenario is the actual representation of status of each tank what have been happening during the last 50 years or half a century. As per observation, it is observed that areas of almost all the tanks have been badly effected and reduced by 30 to 40% in comparison to actual area as per record. The living beings status are also going to decrease day by day. All the wetlands possess different types of pollution which are harmful for crops and other plants as well as animals which depend on tank water. As per Meteorological Department’S record, maximum temperature before 50 years was 40
