The main causes of hunger
Poverty is one of the main reasons why people are suffering from hunger;
because they do not have access to food.
Soil degradation (break down and loss of fertility of the soil) caused due to
erosion and Stalinisation (build up of salt in soil). Therefore, farmers are
unable to sell their crops.
Many farmers use their farmland over and over again which is why their
land is losing fertility.
Natural disasters ruin the crop fertility. (Floods, draughts, etc...)
Political instability and wars also affect hunger.
Describing the graph trend
The above graph shows the amount of fertile arable land (in hectares per
capita) per person each year. Since 1987 till 2001 there has been a decrease in
hectares per capita. The decline is very slow.
How did Europe increase food production after WW2?
After the war the government made sure that the food production increased
which was achieved by intensive farming; using machine, pesticides and
fertilizers which was faster and more efficient. Larger areas of land were
cultivated which increased food production rapidly.

varieties of seed for crops such as wheat, sorghum and rice, and a huge
increase in the use of fertilisers, pesticides and irrigation. It also included
teaching the farmers how to improve their crop growth. One of its major
effects was that it increased food production in Asia dramatically.…read more

Sub-Saharan Africa
The above graph shows the changes in grain yield per hectare in Latin
American/ Caribbean, south Asia, and Sub- Saharan Africa. It suggests that
after green revolution the yield in South Asia and Latin American increased
dramatically. On the other hand, in Africa there has been no green revolution.
