What Are The Advantages And Disadvantages Of Rainwater Harvesting

According to the International Water Management Institute environmental research organisation global water stress is increasing, and a third of all people face some sort of water scarcity. Where demand exceeds supply and no effective management operates, there will be conflicts between the various players involved.

Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.

The world’s supply of water is in steep decline as more and more is being used each year by more and more people around the globe. Currently, 800 million people do not have access to a drinking source. At the current rate, 1.8 billion people could be living in areas of absolute water scarcity by 2025.

Water is the biggest necessity for all humans to have on this earth. Every person needs water in their body to be able to live. Other than drinking, water has many more uses that people take advantage of. It is used for cooling machinery, it can be used as a source of power, to water crops, and much more. Unfortunately, not everybody has access to a stable water source. Right now, several states such as California, Nevada, and Oregon have severe drought. Many people are unable to use a toilet because they don’t have the amount of water needed to flush it. In fact, 1.6 million people in America don’t have any sort of access to indoor plumbing at all.. Seeing how big of a problem it is, many states have already taken action through various methods to obtain more water. More operations have begun to obtain more water from different sources, and many states have employed methods to clean dirty water and give it to the people. Despite these efforts, the reality is that there are still too many people without access to water, and the level of drought that some of our states have is too much. There is one method that has been used within a minor scale in some other countries that requires some more attention, which is called fog harvesting. Fog harvesting is a method that should be used much more in areas that lack water because it is environmentally friendly, is easy to construct, requires no constant attention or care, and it simply provides a great amount of water.

Areas prone to flooding can be drained quickly or be unaffected, protecting thousands of families and government property from destruction. On the flip side, water shortages are plaguing states like California causing raging wildfires and public unrest. This system can ensure that people across the nation have a safe constant supply of water.

There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is beginning to show its effects in first world countries, but is a current major problem facing lesser developed countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. In developed countries the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the vast majority of the population. Seventy one percent of

The most highlighted activity at the Southbank is rainwater system. Rain Bank stormwater harvesting project in South Bank Parkland, Brisbane is an important demonstration project for distributed alternative water supplies in Australia, providing an alternative solution for future issues and its highlight the profit and importance of having such solution. It has reduced the usage of main water supply, improves drought security and contributes to a cleaner, healthier waterways (Hamlyn,

Some areas of the world are already considered water stressed. In areas that are water stressed, the amount of sustainable water is running low. The people in these regions are in need of new and clean water to start being present. According to Roberts, “By 2050 more than half the world’s

Water, like food, is a necessity for human life that is used for many purposes such as agricultural, industrial, and domestic systems. While water is a common element around the world not all of it is clean and able to be consumed or used by humans. With only a percentage of the world’s water being clean and the use of water increasing, the availability of water around the world has become a common issue in the developing and even the developed world. This may be a smaller problem in areas close to clean water sources compared to areas far from a clean water source but, the availability of water is not strictly based on location, it also depends on the specific political and social needs and issues of the area as well. These all become issues that must be accounted for when deciphering whether water is a basic human right or a commodity and what action must be taken to aid the developing water systems in community’s that lack them.

Some states have regulated the collection of rainwater, but have not necessarily banned the collection. Some states even offer tax incentives for the proper collection and retention of rainwater on your own property.

Wise usage of water helps us in saving money. We have to pay for the water we use. If we use less water, we will have more money left to spend on other things.

Solving the global water crisis moves beyond the technical feasibility stage.(2011). Trends Magazine, (104), 19-24.

Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater, what we drink, bathe in, irrigate our farm fields with makes up only 3% of the world’s water, and two-thirds of that is stored in frozen glaciers or unavailable for our use. Many of the water systems that keep ecosystems thriving and feed a growing human population have become stressed. Rivers, lakes and aquifers are drying up or becoming too polluted to use. Already, 80 countries suffer from water shortages that threaten health and economies while 40 percent of the world—more than 2 billion people—does not have access to clean water or sanitation

Access to clean water is a basic human right and yet people around the world don’t have that right and they struggle to survive without it. The many uses of clean and potable water include water for drinking to cooking other daily purpose. It is reported that over 1.1 billion people lack access to an improved water resource and three million individuals, and majority of them children, suffer and die from water-related disease. The need to improve water quality and providing clean water should be major project for developed countries like the US and so called “well developed countries”.

It is an essential resource for sustaining life as well as central to agriculture and rural development, and is intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as degradation and depletion of natural resources that affect the livelihoods of millions of people across the world. According to the World Bank, (2010) report, water is a scarce resource with multiple interwoven uses that range from drinking water, energy, irrigation, manufacturing things, transport of people and goods among others. The report further states that, more than one-sixth of the Worlds’ population does not have access to safe drinking water, with 80% living in rural areas thus access to water cannot not be guaranteed globally.
