Evaluation of the causes of hunger
Unlucky geography- low precipitation and drought, poor soils, steep relief, too hot,
too cold, frozen soils, swampy marshland. People living in these areas cannot obtain
yields high enough to feed themselves.
-however, people tend to only inhabit areas that have productive
capacity and if it does not technological advances, improved irrigation
combined with fertilizers and drought and disease resistant crops are
used to make land productive.
Natural hazards such as floods, strong winds, drought, volcanoes, mass movements
and tsunamis can devastate landscapes and crops can be destroyed in the short term
leading to food shortages.
-however, severe and devastating natural hazards occur rarely and
lead to only temporary shortages. Food aid often fills the shortfall and
prevents malnutrition. The cause of hunger brought on by hazards is
not the natural hazard but the area's lack of capacity to cope.
Population pressure- rapidly rising population is leading to increased demand for food
and supply cannot keep pace with demand.
-however, having larger families is often beneficial for families
living in extreme poverty. For people employed in subsistence
agriculture, children are an economic asset as they can work as
labourers and water carriers to boost food yields.
The land ownership system. In poorer regions where land is passed down to families.
Rising population pressure leads to repeated subdivision of land.
-however, this often fuels rural to urban migration and it can be
argued that this can create market of food and increased efficiency.
Water-agriculture accounts for 70% of water use in the world. As water courses
become depleted, mismanaged and polluted, food yields are put under pressure.
-however, much of the water pollution is caused by6 increased
nitrates from fertilizers used to increase yields so in order to have
more food, more freshwater pollution may be necessary.
Poverty and the cost of food. As demand for food grows and supply is under
pressure, people cannot afford to purchase food.
-however, this is now the most accepted reason given for food
shortages but it is not a satisfying answer, however then we have to
investigate what causes poverty.
Urban sprawl- the growth of cities is eating into productive agricultural lands which
may contribute to lower yields.
-however, the urban expansion is often fuelled by immigration
from rural areas. Urbanisation and industrialisation may improve
people's standard of living and mean they can afford more food.

Population and resources
A rapidly increasing proportion of the world's farmland is not used for food crops but
to produce other resources sometimes much needed but sometimes inessential. An
increased proportion of usable farmland is being used for non-food crops- bio fuels
and other cash crops.
-however, the economic benefits of this include reducing prices of
fuel and improved transportation and increased industrial8isation
which may raise people's incomes lifting them out of poverty.
Cash crops- tea, coffee, bananas, cocoa, flowers.…read more
