Introduction
UN General Assembly "RESOLUTION," on July 28, 2010, explicitly acknowledged that clean drinking water is essential for the realisation of all other human rights, including the right to life. A mandatory draught is therefore provided to encourage all governments and organisations to think about providing clean, safe drinking water, sanitation, and other essentials for the poorest nations on the planet, as well as transferring money, technology, and human resources. The World Health Organization (WHO) specifies the bare minimum amount of safe, sufficient, and affordable drinking water needed to meet the needs of individuals and families. Article 1.1 of the General Comment No.15 of the Committee on Economic, Social, and Cultural Rights states: "The human right to water is indispensable for leading a life of human dignity." In order for other human rights to be realised, this is a necessary condition. Furthermore, it has a significant impact on the achievement of the Millennium Development Goals (MDGs) (MDGs). Only 2.5% of the world's fresh water supplies are sufficient to meet human survival demands, according to a comprehensive analysis of water distribution patterns.
Fresh water is concentrated in frozen and subsurface forms, with only a small amount of surface water available for immediate human consumption. About 20.9 percent of the land's surface water is collected in lakes, while rivers account for only 0.49 percent, and the remainder is trapped in glaciers. We want to know how we can better manage our water resources in light of our ever-growing population and our watery needs in today's world. Concerns about food and water security have become a point of contention for sustainability, particularly in Third World countries. Thus, this study aims to propose and develop workable solutions to ensure that the population has access to safe drinking water and irrigation.
To ensure everyone has access to safe, clean, and acceptable drinking water, the study focused on the most important parameters. For the most basic needs (WHO), 50 to 100 litres of water per person per day is sufficient. Water that is free of microorganisms, chemicals, and radiological hazards is what is meant by the term "safe." National and local water quality standards were mandated by World Health Organization guidelines. Approval is contingent upon the product's having a pleasing appearance, odour, and taste for both personal and domestic use. Every type of facilitation must be acceptable regardless of the cultural context, including gender, life cycle, and privacy requirements. Finally, it's a matter of being able to get around. Everyone should have access to safe drinking water and toilet facilities at home, school, work, or a health care facility, as this is the right thing to do.
A water source must be within a distance of 1,000 metres. In the United Nations World Water Development Report 2021, over two billion people in water-stressed countries have been affected by a lack of water availability. Every month of the year, at least a quarter of the world's population is forced to endure severe water shortages. In spite of the physical availability of water, more than 1.6 billion people face "economic" water scarcity, which means that they lack the necessary infrastructure to access that water. comprehensive assessment of water management in agriculture,2007.
Another problem is that as the world's population grows, so does the capacity of the world's built reservoirs. Since the 1980s, the global demand for fresh water has increased by about 1% per year. A combination of rapid population growth, economic development, and shifting consumption patterns is largely to blame for these changes. Global water withdrawals for agriculture (irrigation) and aquaculture and livestock use account for approximately 69 percent of total water withdrawals. In some developing countries, this percentage can rise to as high as 95%. "(Food and Agricultural Organization, 2011a).
Climate Change Effect
There are numerous ecological interactions in the rural environment, which necessitates constant monitoring in order to make the best decisions. The ability to better monitor water quality in rural areas has also been greatly enhanced by technological innovations. Remote sensing was used to keep track of seasonal changes in the Gulf of Kutch's water quality.
Seawater intrusion, marine effluent discharges, and natural disasters like a tsunami pose constant threats to rural aquifers' groundwater quality. Tuticorin city's rural areas have been found to have an abundance of major cationic and anionic groups (sodium, calcium, magnesium, and potassium) making groundwater extremely hard and alkaline and unsuitable for human consumption. Mathematical simulations, on the other hand, can predict and visualise the long-term effects of various human activities on the rural water environment. In a fascinating study, the city of Mumbai's sewage pumping system was effectively simulated using MIKE 21 software to determine the maximum amount of habitat damage possible.
Indian Concern
There are an estimated 2,00,000 people who die each year due to a lack of access to safe drinking water, and 21 major cities are on the verge of running out of groundwater by 2020, which will have a direct impact on about 100 million people. Thought and planning can take place in the current situation. (TPA).
