Fresh Water-an Emerging Global Concern with Special Reference to India
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 3, Issue 3
Abstract
The world population was 2.5 billion in 1950, 4.4 billion in 1980, 6 billion in 2000 and projected to grow to 8 billion in 2025 and further likely to increase to 9.3 billion in 2050. Majority of this growth will occur in urban areas of developing countries (UNDESA, 2002). Such an increase in population coupled with higher standards of living will pose enormous strains on land, water, energy, and other natural resources. In the present context, the growing population and resulting demand for water is one of the most significant global concerns facing the mankind currently and in future. The availability and quality of freshwater resources around the world are of growing concern along with growing climate change which has resulted into misbalancing water resources [1]. Understanding the problem of freshwater scarcity begins by considering the distribution of water on the planet. Approximately 98% of our water is salty and only 2% is fresh. Of that 2%, almost 70% is snow and ice, 30% is groundwater, less than 0.5% is surface water (lakes, rivers, etc) and less than 0.05% is in the atmosphere. Climate change has several effects on these proportions on a global scale. The main one is that warming causes polar ice to melt into the sea, which turns fresh water into sea water, although this has a little direct effect on water supply
