global food
factors affecting food supply
climate
droughts and floods can damage crops and reduce harvest yields, in the Sahei region of africa. Reduced precipitation and increased temperatures are degrading soil, making it less easy for crops to grow
technology
lack of farm machinery can lead to low yields
lack of refrigerated storage for foods meaning their shelf life shortens
pets, disease
tropical regions pest infestation
conflict
conflict can destroy crops, livestock, distrust transport, take farmers away from their livelihoods
global shortage of sunflower oil and wheat due to Ukraine
poverty
many LIC farmers can't afford pesticides, fertilisers or top quality seeds
farmers suffer from malnourishment, affecting their availability to work.
impacts of food insecurity
rising prices
food supply falls, prices rise, poor grain harvest ment that prices rose all over the world, poor people can afford a full nutritional meal
soil erosion
overcultizating and overgrazing together with lack of rainfalll can lead to serious soil erosion, in semi arid regions. reducing soil fertility limits food production
undernutrition and famine
undernourishment, weakened immune systems. 800 millions people suffer from clinic malnourishment in LIC.
social unrest
leads to rioting, between 2008-11 60 riots around were linked to food shortages
global patterns of food supply
uneven distribution of food
africa and asia are affected by this making them food insecurity
HIC food security
calorie intake
uneven across world
highest in North America
least in Africa and Asia
reasons for food consumption
econmic
richer countries
afford more variety of food
spend more money on food
increase in meat consumption
animals to eat more grains
population
fastest population in LIC so more food is in demand
less in HIC as less population so less food demand
strategies to increase food supply
irrigation
where not enough water is available
lengthy pipelines that transport water straight too roots of water, sprinkles which are less effective
biotechnology
large scale agriculture development-almeria
advantages
drip irrigation and hydroponic water recycling reduces water use
warm temperatures reduce energy cost
scientific food companies have been set up in area
fresh fruit and veg throughout the year
disadvantages
immigrant living conditions and labour is poor
clash between immigrants and locals
plastic covered land
lots of plastic waste
pesticides afect human health
natural water resources under stress
