Are individuals having the chance to control their payment by using direct debit or is it Direct debit controlling each individuals payment schedule (watch only 1st part of the video) Money is still withdrawn from an individuals account even if there is nothing there. They could face fees from their bank (and sometimes their supplier) if they don't have sufficient funds to cover the payments. Because fixed direct debit payments are calculated using previous consumption figures, some payment amounts will not be exactly equal to the individuals actual usage. This means they may end up paying too much or too little to their supplier. The individual would also lose some flexibility in the way they manage their finances.

When there is a shortage of a product, the price is bid up - leaving only those with sufficient willingness and ability to pay with the effective demand necessary to purchase the product.

Now for Somalian citizens who are faced with a compulsory pattern of living with famine, scarcity can be thought as not invited but already a citizen, despite the environmental constraints of hydro climatically-induced water scarcity and the considerable fluctuations which characterize the natural freshwater supply supposed to exist; a water-stress routine is now an impact on the responsibility of improved water supply for self-sufficient crop production (resulting in lack of food and crop production) as well as the number of these Somalian individuals desperately depending on any flow unit of water available to them from the water cycle. Sadly as stated it is not of a short term crisis but if seen in a medium-term-perspective, water may not be readily available to support improved life quality for this growing African population, so the economy therefore is faced with a great deal of scarcity without knowing what to do about it.
