FBC - A SUSTAINABLE FOOD SYSTEM Flashcards
what are the three needs of the “great balancing act” required to sustainably feed 9 billion people by 2050?
- closing the food gap
- supporting economic development
- reducing environmental impact
how many sustainable development goals are there in the 2030 Agenda for Sustainable Development/SDGs?
17
What is the summary of SDG 2 (Zero hunger)?
to end hunger, achieve food security and improved nutrition, and promote sustainable agriculture
what are some factors affecting changes in the food and agriculture sector?
- income growth
- population growth & urbanisation
- malnutrition
- changing rural communities
- trade
- healthcare challenges
- food insecurity
- soil health & arable land
- climate
- water
- energy

what are some current farming systems? (it’s not all intensive large-scale farming)
- mixed farming
- nomadic pastorlism
- shifting cultivation
- organic farming
- agroforestry

what SDG goal is subsidence farming a critical component of? what links does it have for development issues?
Goal 2 (zero hunger)
- local rights, infrastructure, rural incomes, empowering women
what are some future social and environmental changes that might affect subsidence farmers and their food security?
- sea level rise and flooding
- climate change and desertification (kenyan droughts)
- water availability
- lack of viable land due to overpopulation
- governance issues
how might existing knowledge and future technological advances sustainably increase production? what are some examples?
- using new pesticides in intensive agriculture
- intensifying use of indigenous knowledge in local farming practices
- accurate management of land using GPS
- genetically modified crops
- climate-smart agriculture
- precision farming
what is climate-smart agriculture? it can be used as a technological advance to sustainably increase production. what is it criticised for?
3 elements:
1. increasing agricultural productivity and incomes
2. adapting and building resilience to climate change
3. mitigation of GHG emissions
- increase input efficiency
- change management practices
- carbon sequestration
- waste reduction
- on-farm energy production
criticised for justifying nearly any form of agriculture and for not addressing inequalities in production and distribution.
what is precision farming, which can be used as a technological advance to sustainably increase production?
- technologies that allow application of water, nutrients, and pesticides to the places and at the times they are required
- reduces inputs and environmental impacts
- includes measuring, modelling, and responding to site-specific data, including weather forecasts, soil properties, soil water content, pests, and weeds
- from GPS, robotics, and drones, to low-tech measures like using bottle caps for applying fertiliser to individual plants
what are some other examples of farming methods that could increase production sustainably?
- agrotechnology
- vertical farming
- bivalve agriculture
- lab-grown meats
- using cover crops to improve soils when not in season
- natural mulches
we need a sustainable food system- including increased supply, improved efficiency, and reduced environmental impacts. a single solution won’t be enough, need a combo of solutions. it’s not just about food production; must consider what three issues?
must also consider constraints and trade-offs, like what?
- economic
- social
- environmental
e.g. between biodiversity and food production
