The potential for sustainable food supplies Flashcards
sustainable development
development which meets the needs of present generations without compromising the ability of future generations to meet their needs
what are the reasons why current food production is unsustainable?
-food miles
-chemical productions, using fertilizers
-overcultivation and overgrazing in LICs
-farming in HICs is energy intensive
what are the reasons why current food consumption is unsustainable?
-food waste
-food loss
-it’s uneven across the world
-increasing meat consumption
-eating food out of season
what are the different types of food supplies?
-organic farming
-permaculture
-local food
-seasonal food
-urban farming
-sustainable meat and fish
what is permaculture?
creating food production systems that co-operate with nature to care for the earth
what is urban farming?
when gardens are created on unusual land in towns and cities
what is sustainable meat and fish?
involves small scale livestock farms
what are the benefits for the local environment of organic farming?
-stops monoculture which is bad for biodiversity
-less likely to have outbreaks of disease for livestock
-support biodiversity
what are the benefits for the local environment of permaculture?
don’t use crop rotation so keeps the nutrients in the soil
what are the benefits for the local environment of local food?
produces more fertile land
what are the benefits for the local environment of seasonal food?
reduces the energy used to maintain greenhouses
what are the benefits for the local environment of urban planning?
-set up by community groups as part of a social movement
-contribute to income and nutrition by providing fresh fruit
what are the benefits for the local environment of sustainable meat and fish?
-helps to maintain the landscape
-doesn’t impact the local species
what are the benefits for the global environment of organic farming?
-doesn’t use fertilizers that contribute to 1% of atmospheric pollution
-prevents damage to water
what are the benefits for the global environment of permaculture?
-instead of using pesticides they use natural predators such as ladybirds to control aphids
-has a minimal impact on the natural environment
what are the benefits for the global environment of local food?
-improves food quality
-reduced food miles means reduced CO2 emissions
what are the benefits for the global environment of seasonal food?
reduces food miles which reduces CO2 emissions
what are the benefits for the global environment of urban farming?
important part of food security
what are the benefits for the global environment of sustainable meat and fish?
-reduces the cost to the environment
-doesn’t harm the ecosystem
what are the benefits for the local people of organic farming?
less food loss
what are the benefits for the local people of urban planning?
increases the connection people have with food production
what are the benefits for the local people of sustainable meat and fish?
-allows the animals to exhibit more natural behaviour as they are free range
-welfare standard is higher
what are the causes of food loss?
-poor storage
-poor transport
-poor packaging
how much of food produced for human consumption is lost or wasted?
approximately one third
how much in pounds does the average family lose in food waste?
£700
does rotting food impact the environment?
yes, rotting food produces methane which is ten times worse for global warming than CO2
what are some ways to reduce food waste?
-buy vegetables that are in their natural state
-supermarkets could sell in more suitable numbers
-buy one get one free deals (promotes food waste)
-buy only what you need
