sustainability Flashcards
what is a sustainable diet?
low impact on environment, contributes to food and nutrition security and healthy life for generations, respectful of ecosystems, affordable, safe and healthy
what are the 3 levels of recommendations for “setting the table”
- large (big) and immediate impact
- medium impact
- smaller impact
what are the 3 ways of making a diet more sustainable for health, environment and economic and social impacts
- reduce consumption of meat and dairy products
- reduce consumption of food and drink w/ low nutritional value
- reduce food waste
what are the 2 ways of making a diet more sustainable for changes that have gain in on and negative impact in another
- increasing consumption of fruit and vegetables and field grown
- consuming only fish from sustainable stocks
what are the 2 ways of making a diet more sustainable for change that will make smaller contribution to making our diet sustainable, with largely complementary effects
- reducing energy input e.g. instead of driving walk to supermarkets
- drinking tap water instead of bottled water
what number SDG is targeting food waste
goal 12
what is food loss from
food lost in the industry and supply chains, including post-harvest losses
e.g. not having enough workers to pick all the apricots
what is food waste from
the retail and consumer levels,
e.g. supermarkets onwards
what areas are the national food waste prevention project looking at
- households,
- cafes,
- supermarkets
what has research found about were the most food wast comes from
household - consumer part of food chain
how do we achieve a sustaibable diet
- eat lancet
- blue dot
what 3 things in the EAT lancet report 2019 have they tried to achieve
- change eating habits
- improve food production
- reduce food waste
what is the main GHG that influences climate change
Carbon dioxide
name the GHG in order from largest to smaller
- carbon dioxide
- methane
- Nitrous oxide
- fluoride gases
where does methane come from
increase dairy cattle population - bi products of cows
where does carbon dioxide come from
fuel used on road transport/ construction sites
where does nitrous oxide come from
agricultural soils, from increase in fertiliser
where does fluoride gases come from
industrial and household refrigeration and air conditioning systems
what are the 2 largest contributors to gross emissions
agriculture and energy sectors
how much of global emissions come from food
1/4 of GHG
how much of food emissions come from animal products
more than 1/2
how much of all farmed animal emissions come from beef and lamb
1/2
what is the emissions trading scheme (ETS)
key policy tool for reducing emissions and meeting targets
what does the zero carbon bill mean
zero emissions by 2050
what effect of climate change has on health
climate change will make life hard for people who are already suffering (lack of money), e.g. damp homes will effect respiratory health will only get worst
what is the life cycle assessment
a framework for estimating and assessing the environmental impacts attributable to the life cycle of a product e.g. beginning to end of a product
where do most of the GHG come from = which section of the life cycle
farm
when carbon footprint is measured per kg of food, tofu has the lowest impact and lamb the highest why?
tofu is the lowest for plant products, and will have lower carbon dioxide than animals because there is a lot of packaging needed for farms. ruminant animals will have issues with fermentation
what impact does tropical fruits transported by air have on carbon emissions
high - because they have to travel by plane which used alot of GHG
what are the sustainable food guidelines
eat plants, legumes, reduce meat (beef and lamb), sustainable seafood, drink tap water, reduce processed foods
how much food is wasted
1/3
what is food security
ability of individuals, households, and communities to acquire appropriate and nutritious food on regular basis
what is food sovereignty
right of people and healthy culturally appropriate food through sustainable methods
how much food is wasted in NZ
1/3
