Sample Essay: Water Privation


Water privation entails the insufficient supply of quality water. The commonness of water depletion in many of localities has largely been common, even as this pattern shows clear signs of worsening; future water privation on a global scale is almost a certainty. At this very moment, more than ‘a billion people in developing countries,’ (Siegel, and Talantis (63-64), has access to safe drinking water this has caused economic and water poverty (Lall, Heikkila, Brown and Siegfried 1-17). This trend calls for quick and proper measures to be implemented by various governments and departments that oversee the water supply, to guarantee adequate safe water for all. The most appropriate way of mitigating hardships of water is through integrated river basin management.

Not usually a sensible foreboding. But human’s most grave problem in the 21st century may not be conflicts or famine or illness or even the disintegration of civil stability; it may be the inadequate supply of fresh water. Population increase, pollution of the environment and climate change, all enhancing, thus are expected to unite to present a swift decrease in the supply of water in the near future, according to Lall, Heikkila, Brown, and Siegfried (1-17). Actually, that supply is by now problematic for up to a 30 percent of the world’s population.

Currently, 1.1 billion persons lack access to safe water and further 2.4 billion lack proper sanitation facilities; such populations are found in the developing economies. Yet the reality that these statistics are likely to deteriorate inexorably has not been correctly handled by the world community. In spite of apparent status of the predicament, political dedication to overturn these tendencies has not been in practice (McCarthy 1). Grappling with inactivity at the management level and a globe’s population not properly abreast with the degree of the challenge, the international water privation will reach unparalleled levels in the coming years.  Acute water privation translates to hunger, ill-health and death. MacCathy (1) suggests the report released by World Water Development Report in 2003 confirms an alarming projection. By the mid-21st century, the worst scenario of water scarcity is likely to visit no less than seven billion persons in 60 states, but if the proper policies are implemented this trend may be reversed to two billion individuals in 48 states.

Even though water is an easily accessed stuff on the planet, only 2.53% of it is not salt, the rest is saline. Additionally, of the freshwaters, 65% is frozen and locked up in icecaps and lasting snow cover. What is obtainable, in lakes, aquifers, rivers, and precipitation run-off, is now coming under more and more pressure from numerous directions at simultaneously. Population increase is the prime propeller. The augmenting numbers of humans to over six billion by 2000 meant that the consumption of water nearly doubled in five decades. It is notable, between 1970 and 1990 accessible per capita supply of water decreased by 30% (MacCathy 1). Although birth rates are currently slowing, globe population is still expected to augment by 50% as much for the second time, to almost 9.3 billion persons by 2050.

Demand, actually, comes not merely from the necessity to drink, the need to clean and the demand to handle human waste, significant though comprise these issues; the really enormous calls on the supply of water which originates from industrial sector of the developed economies, and, in the increasing popularity of the agricultural world. Imperatively, watering of crops grown in hot arid lands consumes 70 per cent of the entire water used worldwide. Pollution, from manufacturing industry, farming and not least, sewers, adds another vicious pressure. Close to 2 million tons of human waste are channeled every day into water sources. According to MacCathy (1) one liter fecal material is enough to contaminate almost eight times the volume of fresh water. Currently, reports estimate indicate that all over the world there are close to 12,000 cubic kilometers of wasted water, which is far more compared with the whole amount available in the globe’s ten largest rivers at any particular moment. Nonetheless, it can be noted, if rate of water pollution and population growth increases uniformly, the world will eventually cede 18,000 cubic kilometers of the resource within the next four decades; this will be approximately nine times the volume all countries presently use for watering crops.

All that is not proper; though enhancing the pressure on the supply of water, further is climate change. The effect of climate change as projected by UN scientists is likely to account for almost 20% of the enhancement in water privation. While more precipitation is projected to pound in high latitude regions during winters, such as northern Europe, and Britain, in several drought-prone regions, with an extension to a number of tropical regions, rainfall is expected to decline further. Eventually the quality of water is likely to worsen with increasing levels of pollution and varying water temperatures Siegel, and Talantis (62-65). Additionally, the threat of the global growth of towns: currently, 48% of the Earth’s inhabitants reside in urban areas, and within the next two decades, the proportion is projected to hit a high 60%. Urban areas usually have more easily available clean water supplies compared to rural ones; nonetheless, their challenge is that such township areas concentrate wastes owing to poor sewer systems. MacCathy (1) notes: “Where good waste management is lacking, urban areas are among the world’s most life-threatening environments.”

The gravest, direct repercussions of water privation will apparently affect human health. The availability of clean water can be perceived as both trivial as well as an advantage: Water-related infections are among the most prevalent causes of human ill-health and death. In addition, water-borne diseases, for example gastric infections resulting to diarrhea, are caused by consuming polluted water; vector-borne illnesses, for instance schistosomiasis, and malaria are transmitted by the small snails and mosquitoes that use water as their breeding places. Millions suffer from such infections. In 2000, 2.2 million people were suggested to have passed on due to water and sanitation linked illnesses; about half the number died of malaria. The greater part of the victims was below five years of age. The world’s increasing need for fresh water has also been linked to soaring environmental strain; 60% of the globe’s largest rivers have witnessed their stream flows disrupted by reservoirs and, of the living things that prefer inland aquatic environments, thus affecting the existence of 24% of mammals and 12% of birds.

It is notable, one such agency is the Global Water Partnership (GWP), which was created by institutions like the World Bank and the United Nations (GWP). GWP can provide the technical expertise, advice, and funding sourcing that certain governments may require.

The main technical procedures in IRBM is the restoration of freshwater ecosystems, which encompass re-planting of trees in riparian areas, reconstructing stream waterways form and in-stream ecosystems, removing hindrances or implementing simulations of natural flow systems, reducing eutrophication in large water bodies, restoring water flow to reclaimed wetlands and reinventing native species. Re-establishment of innate uses of land within catchment areas is also another class of activities that is imperative to a lasting program for a deteriorated aquatic system. Some agencies and communities believe that water pollution phenomenon the most effective way to prevent water privation, rather than IRBM, which they say is not realistic and mere paper pushing.

Pollution prevention is the aim of water pollution control, instead of pollution treatment. Pollution prevention and minimization of waste encompass non-technical and technical measures aimed at the prevention of the production of pollutants and waste (Helmer and Hespanhol 1). “It is the conceptual approach to industrial production that demands all phases of the life cycle should be resolved with the aim of minimizing or preventing harm to humans and the environment. This involves the design phase of the product, the selection, fabrication and arrangement of raw materials,” the production and assembly of final products, and the management of all used products after their usability is over” (Helmer and Hespanhol 1).

Siegel, and Talantis (63) suggest that water privation in the future is almost a certainty because of the abuse that our water resources are being subjected to. Right now, more than a billion people are suffering from the gradual depletion of water resources. Despite the fact that the surface of the earth is mostly covered with water, this is not relevant because the issue is the supply of fresh water. The most sustainable and effective way to address the possibility of water privation is through river basin management. It has several stakeholders consisting of international agencies, business, and more importantly, the people themselves who share the water. Some people believe that water pollution control is more effective but this is not the case.

One feasible approach to mitigating the challenges of recognizing non-point source contaminators is to ensure all industries producing diffuse contaminats undertake the implementation of practices and technological innovations that decrease the release of polluting substances into waterways (Siegel, and Talantis 62-65). For instance, all cultivators could grow riparian buffers purposely to help in nutrient filtration or cover crops to decrease leaching. Alternatively, ranchers may opt to protect water ways using fences to restrain livestock dung from being washed to the waterways.

Conclusion

Generally, water pollution control does have its merits, but poses problems like toxicity that could potentially harm the water itself and the species subsisting in it, as well as being very costly. Water pollution control is also part of river basin management, although from a broader perspective. Because of the far reaching scope of river basin management, the perceived disadvantages of water pollution control are mitigated. In fact, water pollution control can only be effective and sustainable if used under the process of river basin management.
