New thinking and future of agriculture Flashcards
we will grow more food in the next ____ years than in all previous history of humanity and agriculture
50
Things that make the food supply system chain more complicated
more people with more money that live longer
increasingly urban, non-agrarian with complex food demands
what is important about the calories that are produced in the future
It is not just about the production of calories, it is about producing a well-rounded diet for everyone
main factors that affect food prices
wars, civil unrest, weather (mainly weather)
heterosis
genetically uniform F1 generation hybrids
apomixis
seeds without sex
What trait are they trying to breed the modern crops to have
we want bigger, more dynamic roots
Canadian no till agriculture absorbs the equivalent of CO2 from _________ cars annually
2 million
gene editing; CRISPR technology
allows for specific cuts of DNA that allow for many things
types of DNA changes possible with CRISPR
indel mutations, gene deletion, gene insertion or replacement, gene correction
example of gene editing
blight resistant potatoes
the golden rice project
how does wifi and cell phones help developing countries
undeveloped countries can use solar panels to charge phones. Apps allow access to different ag needs (identify pathogens/pest, access to knowledge without education
vertical farming
tall buildings with greenhouse outside, other farming inner core, integrated farming models
benefits of vertical farming
recycling and utilization of wastes from one production for another
local fresh food in cities
Mixed-use tall buildings
problem with vertical farming
how we will have to supplement with light during winter
factors included in vertical farms in urban environments
controlled environments
integrated farming
waste reduction
energy generation
rural to urban shift
urban farmers
pathogen containment may be difficult
avoid seasons and weather
problems to solve with vertical farming
economic feasibility (expensive to start, maybe not very energy sufficient)
Environment is hard to manage (pathogen outbreaks
waste management
is it sustainable
benefits to vertical farming
urban ag sovereignty
controlled environment, making yield predictable
organic produce, reduced fertilizer and pesticide
could be more sustainable if run and built right
wastewater treatment
decreases organic matter and number of microorganisms in human waste-impacted water
example of wastewater treatments
constructed wetlands. Built by engineers to mimic natural processes in rivers (except intensified and controlled)
anaerobic digestion
reduces amount of sludge for disposal and turns it into fertilizer for ag
does produce methane
way to improve composting
source separation, recycling, combined urban composting and water waste
source separation
reduction of waste into separate recycling paths that separate compostable from non-compostable
recycling
recovery of material that helps energy recover and improve ecosystem health
composting
large scale controlled decomposition process with complex microbiology
what process does composting resemble
fermentation
