A natural resource is defined as a natural material found on earth that is useful for humans in some way. It is often processed of manufactured in order for it to meet the needs of a society. Resources then differ spatially, as different people have different needs and therefore require different resources, and temporally as a society grows and advances their needs will change and so to their resources. Natural resources range from minerals and metals to people (their labor and skills). (Kleeman 1997, Pashley 1996, Plant 1998) In this response 2 major sample studies will be used, these are, water and energy (in the form of uranium) on a variety of scales. Reference List Internet The Uranium Information Centre.

web Sydney water web Sydney Catchment Authority web web web Book KLEEMAN (1997) Global Interactions: A Senior Geography Rigby Heinemann, Australia PLANT (1998) Get Smart Study Guide Science Press, Australia PASHLEY (1996) Excel HSC Pascal Press, Australia Natural resources are natural materials found on earth that is useful for humans in some way (Kleeman 1997) They can be divided into categories. Diagram 1 shows the 4 types of natural resources and an example of each. From the above we can see that coal is an example of an exhaustible resource, this means there exists a finite stocks. These resources are non renewable in the ascertainable future. Renewable resources, have the potential to be renewed.

Forests will be replenished over time after they have been harvested for human needs either naturally if left alone to do so, or with human help in the form of plantations in an alternate area. Renew ability is then often dependent on proper management over time. Recyclable resources are also renewable but can recycled indefinitely through reprocessing. These resources will not always come back in the same form after undergoing recycling.

Glass bottles can be recycled into furniture, windows, ornaments, etc. Continuous resources are continually renewable. Solar energy will always exist and can be harnessed and used without concern for recycling or replenishment time. It can be said that it will never be finite and the supply will always be greater than the demand. Question 3 Natural Resource: Uranium A variety issues arise when uranium is found, extracted, processed, consumed, and disposed of.

Management strategies are in place to combat these issues. Environmental Issues The use of uranium produces waste has an impact on the environment. Waste produced is radioactive and therefore hazardous, depending on the wastes level of radioactivity and half life it will remain hazardous for a long period of time. The environmental issue effecting uranium is waste disposal.

The view below is from Panama Resources, a US company that seeks to dispose of nuclear waste in outback Australia. nuclear waste is a problem that wont go away, that the best known way of dealing with it is putting it somewhere in stable rocks, that these rocks must be away from population centres (Campaign for a Nuclear Free Future Update 17 Dec 98) Table 1 shows radioactive waste scales and their individual disposal method. The burial of waste, in the short term has been a suitable method but in the long term proves to be uncertain. There are always risks of the radioactive waste leeching out into the soil and impact on the biophysical environment. Diagram 2 shows the spread of radioactive contamination via abiotic processes to the biota. Source: web URANIUM ISSUES Unless a proven long term method of waste disposal is developed, uranium will loose resource value as demand decreases due to environmental and concerns.

Social Issues The Mirror of the Northern Territory are concerned about the Jabaluka uranium development, and any development that impacts on their cultural sacred sites and traditional way of life. They are traditional owners of land. They claimed much of their land back under the Aboriginal Land Rights (NT) Act 1976. They claim to have sacred sites in the uranium mine area.

These sites are directly and severely impacted upon by the Jabaluka uranium mine. The Mirror believe that culturally significant sites will be damaged by the construction of the Jabaluka uranium mine. Damage to these spiritual sites destroys living tradition. The indigenous population, with support and backing from a very much diversified global community struggled against adversity in the fight to stop the Jabaluka uranium mine and were successful in doing so. As of September 1999, all work at Jabaluka ceased indefinitely which has effected resource by reducing supply. Question 4 Natural Resource: Water Water is the most plentiful, vital, non-substitution al resource on the planet.

Life exists and is sustained because of and by water. Though there is abundant water in the world and available for use, attainable potable water for human consumption remains scarce. Map shows the global inequitable distribution of water on a global scale. Water is needed by all but all do not have equal access to supplies. Due to the scarce nature of water it is necessary for management strategies to be practiced to ensure optimum uses of water are not hindered by damage to water quality and limited water quantity. A case study of Sydney water will demonstrate water management strategies utilized, their results and suggest enhancement of these strategies to ameliorate water issues on a local scale.

Sydney water provides approximately 1500 million litres of water per day to more than 3. 7 million people. Map shows the Catchment area and the infrastructure that supplies Sydney (33 51 S, 151 12 E) with its water. The following flow diagram illustrates the path of Sydney water from Catchment to where it is used in homes and businesses Catchment water collection Dams water storage Filtration Plants removal of contaminants Uses Residential Industry Businesses Management strategies currently used in Sydney are aimed to secure adequate quality water for consumption and use by the population of the Sydney region. These strategies are also devised so that there will be access to sufficient amounts of water for all. These strategies include: Water recycling Thus providing another water source and reducing anticipated increased future usage. Also reducing discharge into rivers and oceans.

Recycled water is used in residential gardens and toilets, in industry and irrigation so that fresh water can go directly to the people for consumption. This then leaves the present infrastructure able to withstand present demands without the construction of new infrastructure. Irrigation practices increasing water efficiency e. g.

central pivot sprinklers and drip or trickle systems Design features of Infrastructure e. g. The Prospect plant (and others) were designed to be easily upgraded (SMH 98). So when new technology evolved and new information accumulated the plants could be ready to put them in practice, put them to use.

Pay per use Consumers are charged for water usage as the following diagram illustrates. There is then an incentive to use less, conserving the resource, because of reduced costs of consumption. Public awareness and education programs National programs such as Water Wise which aims to inform and educate the community on how to use water wisely and promote the need for water conservation (web). Also specifically Sydney water conservation campaigns such as Sydney water: Good enough to bottle, too good to waste Monitoring of the system and water quality Managing the levels of contaminants and foreign particles in the water to ensure the public has access to the optimum water possible. These strategies and others used are effective to a certain degree though are not always faultless as the 1998 Sydney water crisis pointed out. Cryptosporidium and giardia parasites entered the supply system jeopardizing public health and safety which emphasized the need for the evaluation and improvement of the current management strategies being employed.

Suggestions for improvements of management strategies water recycling More water recycling for all uses so less water is deducted from storage facilities Irrigation practices The spreading of the new efficient methods so the benefits can be felt throughout. Implication of new technology to existing infrastructure As new technology is made available it should be put to use. Water costs Put the user pays principle to further use. All costs of getting the water to the consumers, building the infrastructure and the environmental costs are factored into the costs to the user. Consumers would then be hesitant of the inevitable new dam because they would have to finance it themselves.

They would be forced to conserve. Public awareness Strengthen campaigns to make the message loud and clear. Monitoring quality Develop and strengthen regular thorough checks on water composition. Set strict tight controls on acceptable levels of parasites and ensure these are met and not surpassed. Other suggested strategies Quotas and limits If these are preceded, heavy fines should be demanded Weather forecasting If the weather is accurately predicted it can be known when demand will be at a high (when its hot) and when supply will be abundant (when it rains heavily for a prolonged period of time) Population reduction Migration restrictions and incentives to move elsewhere to reduce the population hence reducing demand (provided demand per head does not increase also) Water management in Sydney is a long term process but the strategies used must be evaluated in the short term for the strategies to be effective. Water provision is a function of a city and the people of the city have a right to assessable clean water.

This can be granted and sustained provided the proper management strategies are set in place and new ones are continuously developed and implemented. Question 2 The spatial distribution of the worlds resources is inequitable. Humans have no say or no hand in where the majority of natural resources are located. It is the physical processes that brought about the appearance and the make up of the earth as we know it today that is the force behind the scattered non-uniform distribution of worldwide natural resources. The maps below illustrate the distribution of some examples of natural resources throughout the world. The reason behind the differences between production and consumption of natural resources lies in the fact that the so called North countries or the developed countries industrialized early on and first.

They then depleted their local resource stocks temporally and were compelled to search elsewhere for the resources to satisfy their needs. To do this they turned to the developing world and exploited foreign resources. A cycle of supply and demand was soon afterward created, where the demand originated from the developed countries who saw the supply of cheap raw materials and cheap labor, and the supply emanated from those the developing counties who sought to the capital develop. Distribution and consumption evolved to be based on wealth. Access to and supply of resources is granted to the country, corporation or company that makes the most lucrative offer. Typically the developed nations of the world are in a position to do this, but as discussed above, not locally.

They have the means to consume what is produced elsewhere. In percentage figures this translated to 90 % of the worlds resources being consumed by 30 % of the worlds population. Technology has played a part in creating disparities between production and consumption. Transportation carries resources all over the world, no longer is there a need to locate near the resource you need to have access to it. Example: The map below indicates uranium production and consumption on a global scale.

The trends, as can be seen from the map, uranium is produced in areas where it isnt consumed. The wealthier nations with the money for nuclear electricity generation import their needed uranium. The producer / supplier nations do not have the same needs for uranium so they export it. Political Issues In todays unstable state of the world international and national conflict and aggression is a prevalent concern. So too is the world armament and defensive measures that exacerbate these concerns. Nuclear weaponry is a concern on a global scale because of its potential cataclysmic damage it could inflict on the world.

Measures have been taken to prevent this. The International Atomic Energy Agency was set up by the United Nations in 1957 to help countries develop nuclear energy for peaceful purposes. Safeguards are in place to discourage the change of course of nuclear material from peaceful use by increasing the risk of early detection. e. the principle of prevention by stopping it at the source as opposed to the cure after a warhead has been fired.

When Australian uranium export was approved it was under the condition of safeguards which meant that countries importing Australian uranium did so under the strict condition that is was used specifically for peaceful purposes, namely electricity generation and not for military purposes. The pie chart below shows Australias uranium exports Other forms of Political issues include government policy such as the three mines policy by the 1983 Hawke Labor government. By only operating 3 mines this limits supply. Conclusion Natural resources are present in different categories: exhaustible, renewable, recyclable and continuous. On a global scale spatial and temporal variations on the distribution and production and consumption rates and levels exist.

Differences in production and consumption of natural resources arise because of environmental, social, economic, and political factors. In the finding, processing, consuming, producing, and development of natural resources issues emanate. These issues include that of a social, political, economic, environmental, and technological nature, But management strategies are formed and utilized to confront these issues. Management strategies are based on the conservation of natural resources and maximizing their efficiency in meeting the needs of society without damaging people or the environment...
