According to a research done by Mwingi Godfrey on the conservation of water in South Africa, the following is important to ensure a sustainable use; Pressure management, this will control the chances of pipe bursts thus reducing the amount of losses through leakages, and in connection to this is the repairing of the faulty pipes and tapes to reduce the leakages. It is also vital to put up water meters for drafting payment schedules, this reduce the amount of water used for both domestic and commercial purposes.
Water used for washing dishes and in flushing toilets is also a lot; therefore, re-use should be considered as some water can be used twice, this is called grey water. Dual flush system should be adopted because of its minimal water usage.
In case of irrigation, conservative measures should be applied such as mulching and watering at the right time to avoid wastage Water conservation para. On energy, it is important to consider all the types of renewable energy sources such as wind, tides and waves, solar and biogas energy. If these entire sources are harnessed then the cost on electricity can be greatly reduced.
Solar and biogas are the most efficient sources of energy that can be embraced to ensure a cost effective use. Practices such as putting off lights and all electrical appliances when not in use should be implemented. Use of energy saving bulbs should not be ignored Fourteenth session of the United Nations commission on sustainable development para. In considering forest resources in Africa, it is important to ensure that growing more trees is encouraged by emphasizing on the plant two as you cut down one should be encouraged, looking for alternative sources of energy and construction materials to reduce on logging done daily.
Education campaigns on the importance of forests should be carried out. Conservation of these resources is a long time process which requires a timeframe of not less than five years. For water conservation, all the above mentioned ideas can be implemented in twenty years time, this due to ignorance with the people in Africa and lack of required skills to implement the strategies.
For energy, a period of more than twenty years can be possible considering the lack in technical knowhow, awareness and lack of money to adopt the renewable sources. This case applies to forests because carrying out awareness and huge amount of money is required to carry out a forestation process. There has been recorded a decrease in the overall global population growth rate such that although there is still a growth in the population, the rate is reducing. However, the rate is not evenly distributed.
Instead, only the developed nations where industrialization and modernity are advanced are experiencing the population slowdown. The developing World still has rising rates of population growth I. The reduction in the growth rate can be attributed to climatic changes that have in turn caused people to resort to totally new ways of living. There has been a lot of destruction to the atmosphere and the resultant effect has been that some of the plants and animals that were useful for improving the immunity of the people when included in the diet are now extinct.
Global warming has killed many such plant and animal species; and the other effects have been that there is an increase in strange, previously uncommon diseases caused by climatic changes which are making more people to die faster than before. Life expectancy has also reduced because of these changes Johansen, In addition, the lifestyles of people have changed drastically, including having diets that are less healthy such as the consumption of genetically modified substances whose chemical contents are harmful to the body and shorten life.
This trend is bound to go on for as long as industrial development is going to continue, worsening as the effects of global warming resulting from industrial pollution increase Vormedal, New factors are bound to come into play, including increased child mortality and increased resistance to medication available even as new species of pathogens and parasites emerge with changing environmental conditions.
It is also expected that more people will be less willing to have children as the pressure on available resources increases, thereby pushing the population growth rate down. With globalization opening up doors of nations, more technologies and immigrants are expected to get in, and not only will there be a real pressure on resources available pushing families to downsize but there will also be a massive movement away from the use of natural, more nutritious food items to those that are artificial and developed through technology I.
As such are likely to be more harmful to the body, many people will find themselves less fertile while the fertile ones will be less willing to have more than a few children. The few children born will have a reduced life expectancy due to increased diseases; and child mortality will be very high. As the figure below shows, the population of Canada has been on a downward trend ever since the start of this century.
