Resource definition and classification
Resource definition
Resource is defined as any aspect of the environment that can be used to
meet human demands.
Resources can be either natural or human. Natural resources are naturally
occurring substances such as oil, forests, water, animals which are
considered to be of value by human populations. Human resources are the
number of people in a population and their abilities and skills.
Some countries such as Japan have limited natural resources but have built
up a wealthy economy through their high level of skills. Other countries
which have large amounts of natural resources, have low levels of economic
Resource classifiation
Natural resources are further classified as renewable, semi renewable and non
Semi renewable resources such as soil and forests are often thought of as
renewable as they can regenerate themselves within a human defined time
frame. However, if these resources are exploited at a level greater than
their natural rate of replacement they will become non renewable. This is
often the case with lean water supplies around the world. Water is
considered to be a renewable resource as it is readily available in vast
supplies around the world. However, some areas of the world struggle to
have enough clean water to meet the rising demand of their population. Here
water would not be a renewable resource. Other examples are overfishing,
as many species of fish that would have been considered to be in abundant
supply a few years ago, are now in danger of becoming extinct, as this
resource has not been managed in a sustainable way that would allow the
fish to continue to be a renewable resource. This suggests that the
definition of a renewable resource and a non renewable resource is often
not clear.
Flow resources are renewable resources that don't need regeneration as
they are in constant supply such as wind, solar and tidal power. Due to
problems with cost and technology, these resources have not been used to
their full potential yet. However, in the future the use of flow resources
will increase due to technological advancements and because non renewable
fossil fuels will decrease in availability.
Non renewable resources such as oil, coal and gas take millions of years to
form and therefore in human terms, they are fixed in the amount available.

Resource depletion can occur quickly and eventually resources become
exhausted and no longer viable for extraction.
Natural resources can also be classified as abiotic or biotic. Biotic
resources come from living organisms such as wood; however abiotic
resources such as iron and copper do not originate from living organisms.
Biotic resources are found at the surface of the earth whereas abiotic
resources are found below the surface of the earth.…read more

Changes in the way resources have been used can be due to technological and
societal advancements. These can be illustrated by the following situations:
Food- most of history, food was a resource used for survival and the aim of
technology was to get enough food to survive. Now food is used as a
resource for pleasure especially in westernised cultures such as the UK and
America.…read more
