Food
In many LEDCs both the quality and quantity of the
food supply is poor. Many people rely upon a very limited range of
basic or staple foods such as Rice or Millet.
-
840 million people in LEDCs do not receive enough
food each day
-
Under-nutrition results in tiredness, sickness and
ultimately death
-
Malnutrition, caused by an unbalanced diet, causes
health problems
-
Health problems caused by lack of food mean people
are unfit to work

Food Problems Solved
by!!!!!
-
Irrigation schemes that bring more land into
cultivation, e.g. The Nile and the Ganges Valleys
-
Green Revolution where new high yielding
seeds such as IR8 rice are grown
-
New Technology such as motorised ploughs,
rice harvesters, electrical pumps that improve yields
-
Fertilisers and Chemicals are used to
control pests and increase yields
-
Emergency Aid after drought is provided by
people such as Bob Geldof - i.e. - Live Aid

Geographical Obstacles
-
Landlocked countries with no coastline are isolated
from trade routes which hinders development
-
Soils in the tropics are generally acidic and
infertile which hinders farming
-
Climates are more extreme in the tropics which
results in hazards
-
Tropical climates support more diseases and pests
than temperate climates
-
Dense rainforest vegetation affects communications
and development in areas of Africa & S. America

Pests
-
Pests are animals or insects that consume and
destroy crops
-
It is estimated that each year pests such as
locusts, weevils and rats destroy up to one half of the world's food
crops
-
Most losses occur in poor countries that cannot
afford pesticides or secure food storage
-
One of the world's greatest pests - the Tsetse fly
- inhabits the wooded and grass savannas in sub-Saharan Africa, so
huge areas of tropical Africa cannot support cattle
-
Eradication of the tsetse fly would enable cattle
farming, thus helping to raise living standards
