CONTRAST tropic levels of a terrestrial VS. aquatic food production system
TERESSTRIAL:
food obtained from lower trophic levels therefore less energy lost therefore more efficient food
production system
AQUATIC:
food obtained from higher trophic levels therefore more energy lost therefore less efficient food
production system
How does climate change affect LEDCS?
1. DROUGHTS = causes decrease of crop production and so less food. However some LEDCS have
grow drought resistant crops.
2. SEVERELY HIGH TEMPS= destruction of crops therefore less food
How does technology impact food production? LEDC
low levels of tech eg: basic irrigation/open field = flooding
high levels of labour eg: family labour less food is produced/TIME CONSUMING/HARD WORK
, How do LEDCS use land?
food - exporting to MEDCS
land used for biofuel
REMAINING LAND = edible crops 4 local pop
What are basic facts involved in the imbalance of global food supply?
1/6 world pop=1billion people = hungry
3/4 world pop= inadequately fed/malnourished
if food prices were to increase by 10% = 40million suffering from food poverty
it is estimated that every 6 seconds a child dies from hunger
