Scarcity of natural resources
The shortage is the lack of basic resources such as water, food, energy, housing, etc. that they are considered essential to meet the survival or non-core resources to meet various needs in human societies in various aspects.
Usually a single company does not have sufficient resources to adequately provide the needs of its population resources, so that the trade and commerce of goods and services needed. Scarcity forces prioritize the needs and goals of society.
Shortage of oil
Oil would reach only to the consumption of the next thirty years. As for drinking water, it is estimated that the mid-century can not supply the world demand. This is not only due to population growth, but also the pollution of waterways and aquifers and the effects of climate change. In addition, it is expected that by 2025 the world population exceeded 8,000 million, while the rapid growth of the global economy will increase the demand on natural resources. Therefore, the world will suffer from a growing shortage of vital renewable resources such as land for cultivation, water and forests
Water shortage
As for drinking water, it is estimated that the mid-century can not supply the world demand
Currently, 23% of the population lacks adequate water and by 2025 this will rise to 33%, affecting 50 countries. In the near future the new war will not be for fossil fuels, it is very likely that there are wars water.The animals depend on water to survive, hydration is fundamental to the functioning of our body. But we humans, especially those who must transform some daily practices to contribute our bit in this cause, and stop wasting this resource not renovable.Mientras in several northern provinces there are communities, cities and towns have to survive 1000 liters of water per week, in the best and when they take on the metropolises drinking water is used for washing cars, washing down the sidewalks, washing the dishes with the tap open continuously, people toilet flushing water indiscriminately, among other irresponsibility, as if it were a resource that is never going to end.
The shortage of drinking water, food and arable land will create new sources of interstate conflicts since food security rests on these pillars.
The challenges of scarcity and
climate change (FAO)
-the Natural resources land, water and genetic materials are essential
for food production, rural development and livelihood
sustainable. Unfortunately, for access to these resources it is likely
in many regions increase the conflict has long -present
time in human history due to increased demand for food,
fiber and energy, as well as the loss and degradation of productive land.
The transformation of the agricultural, increased scarcity of water,
loss of biodiversity, extreme weather events and other
effects of climate change will exacerbate the conflict. To safeguard
productive agriculture will have to face these challenges.
Safeguarding water resources
It is anticipated that the world population will increase
of 6.7 billion today to 7.2 billion
in 2015. One of the global challenges
In light of this population growth will be
the ability to produce more food with
less water, increase efficiency in the use and
water productivity and ensure access
equitable access to water resources. Nowadays,
irrigated agriculture consumes around
70 percent of the world's water extraction
sweet. This volume goes up to 95 percent
many developing countries, while the
representing industrial and domestic consumption
about 20 percent and 10 percent,
respectively.
However, there is increasing pressure
industrial and domestic water use and
the need to preserve it for
well-functioning ecosystems. Further,
climate change and the impact of
climate variability in regions
vulnerable pose other challenges. The
amount of water needed in agriculture
for the production of biofuels
will pose another problem.
FAO is an active partner of first
order in UN-Water, a mechanism for
strengthen coordination of all
agencies of the United Nations
dealing with issues
water. The database of the FAO
water, AQUASTAT, contains information and
primary data by countries and regions.
Management of bioenergy
In the long term, increased demand
biofuels could offer a
opportunity in developing countries
to reduce poverty, increase
food security and provide a source
clean energy, but only with political
and appropriate investments. To improve your
ability to provide advice
well grounded in policy
bioenergy, FAO is preparing
a new methodology for measuring
impact of bioenergy
on food security. It is
by testing this methodology to
through pilot projects in Cambodia, Peru,
Thailand and the United Republic of Tanzania.
Climate change
Climate change will exacerbate the problems
current hunger and insecurity
food in many countries. For millions
people living in ecosystems
fragile, climate change may increase
much risk that it unravels thelost crops and livestock. Function
FAO is promoting options
adaptation and help rural communities
to adapt them to suit your needs.
At the same time, agriculture itself can
be part of the solution as regards
reduce emissions of gases that produce
The greenhouse effect. In other words, the
environmental and agricultural agenda should be
closely linked to ensure that
agriculture contributes to climate mitigation,
reduce emissions and fix carbon in
floor.
Since 2005, the FAO runs a process

climate variability.
Factors that will impact severely on sustainability: the continued rapid growth of the world population and increasing economic development. Thus, the demand for water, energy and food will also grow, according to these estimates, between 30 and 50% in the next twenty years. The math does not fail: no natural resources for many people.
