Question

Which year is celebrated as the international year of freshwater?

Answer 1

Hint: As we know that (UNESCO) United Nations General Assembly proclaimed the international year of freshwater to increase the awareness about the availability of freshwater and to galvanize action.

Complete Solution :
- The year 2003 is designated as the International Year of Freshwater by UNESCO. While considering issues of importance to mankind, availability of freshwater was very much as important just as that of greenhouse phenomena.
- We can see some most important points due to which international year of freshwater was celebrated:
- As we know that there is a range of contaminants these can be both abiotic and biotic in origin. As we know that substances such as blue green algal can contaminate most surface waters to some extent.
- It is also found that nutrient waste can lead to contamination of groundwater sources by sources like that of nitrogen compounds, mainly nitrate, also biotic contamination from viruses and pathogens.
- There is a range of contaminants, which need to be considered and their control understood in order to guarantee freshwater supply. These can be both abiotic and biotic in origin. Other anthropogenic compounds such as persistent organic pollutants have become significant pollution problems of groundwater.
- It is found that in 2002, the 6 billion people of that world used about 54% of the available freshwater, both surface ground and ground waters. And irrigation and poor drainage practices also have the disastrous effect as it creates salinization and waterlogging irrigated lands, which if not controlled or reversed, this can lead to desertification in marginal lands.
- Hence, we can say that 2003 is celebrated as the international year of freshwater.

Note: - We can note here the main elements of the resolution are the importance of sustainable freshwater use and to increase awareness or we can say to make the people know about the scarcity of freshwater and protection.
