Marginal considerations are considerations which concern a slight increase or diminution of the stock of anything which we possess or are considering. [4] Another way to think of the term marginal is the cost or benefit of the next unit used or consumed, for example the benefit that you might get from consuming a piece of chocolate.
In each group, the marginal benefit is the same, and between groups, the marginal benefit is decreasing. [ 6 ] The possibility of calculating an optimal allocation allows much more flexibility in water-sharing agreements.
The use of groundwater banking can make water a more homogenous commodity. This can create a market value which will enhance private investment increasing the benefits. [9] It will also align marginal benefit with marginal cost causing the market to come to an economically efficient level. [9]
At low levels of consumption, water has a much higher marginal utility than diamonds and thus is more valuable. People usually consume water at much higher levels than they do diamonds and thus the marginal utility and price of water are lower than that of diamonds.
From a financial or economic point of view it is not appropriate to try to reduce NRW to the lowest possible level, because the marginal cost of reducing NRW increases once the cheaper options have been exploited. Once the marginal cost of reducing NRW exceeds the marginal benefits or water savings, an economic optimum has been achieved. [50]
Researchers also found that adequate hydration can control diabetes, blood glucose levels, and low blood pressure. The incredible health benefits of drinking enough water: New study highlights ...
This is the level at which, in the long-term, the marginal cost of leakage control is equal to the marginal benefit of the water saved. The rate of reduction in leakage has slowed for many companies because the most obvious causes of leakage have been detected and addressed, leaving only less apparent leakage problems. [ 23 ]
The widespread use of toothpaste and mouthwashes with added fluoride in recent decades appears to have diminished the health benefits of water fluoridation, according to a new study.
