Climate change effects on physico-chemical parameters for testing of water in Nepal

Water is most indispensable requirement for all living organisms and any alterations in water may lead to the issue of survival for these organisms. Due to increase in population, industrialization and urbanization, large quantities of sewage and industrial wastewater are discharged into lake has significantly contributed to the pollution of the lake. Nepal is one of the most water-abundant countries in the world, with 6000 rivers, total mean annual runoff of 224 km3 and per capita water availability of 9000 m3. However, the hydrology of Nepal is primarily monsoon-driven, and about 85% of the rainfall happens in June–September. The temporal variability of rainfall and runoff is hence very high, and the problems of excess water during the monsoon, and water scarcity during the dry season, affect all aspects of life in the country. Nepal suffers from different types of water-induced disasters such as soil erosion, landslides, debris flow, flood, bank erosion etc. due to its rugged topography, weak geological formations, active seismic conditions, occasional glacier lake outburst, floods and concentrated monsoon rains associated with unscientific land utilizations. Climate change is a major environmental threat and likely one of the most important challenges of our time. In particular, climate extremes such as heat waves can have a significant negative effect on society. Climate change is a risk multiplier that will put greater pressure on biodiversity preservation, land use planning, forest-health and quality, and water resources. Climatic change increases the variability and magnitude of natural weather events and increase uncertainty about adequate and appropriate natural. All above impacts have resulted in the deterioration of water quality of river and lakes. It gives the clue to develop appropriate management strategies by municipal authorities. Hence it is essential to examine the quality of water by different parameters as stated above before using the water
