Q

what effect does climate change have on agriculture?

A

1) excessive precipitation, floods and planting difficulties
2) new pests, disease pressures: competetion and crop damage
3) drought, crop failure

Q

causes of wetland destruction

A

drainage and filling, dam construction, sea level rise, water pollution, channelization of riverbeds, overexploitation of resources, invasive species

28
Q

ocean acidification

A

the ongoing decrease in the pH of the ocean
-threat to the entire marine web

29
Q

best way to secure the food supply

A

increase ag productivity

30
Q

threats to ag productivity

A

1) lack of pollinators, desertification, salinization of soil, ocean plastic, biodiversity loss, loss of arable land

31
Q

in terms of the future of food security,

A

we need to deprioritize optimization and prioritize resiliency and make sure we are prepared for disturbances

32
Q

how to frame food security as a individual issue

A

as a population growth issue rather than a malthusian scenerio

malthusian : theory that population tends to increase at a faster rate than its means of subsistence and that unless it is checked by moral restraint or by disease, famine, war, or other disaster

33
Q

neo malthusian

A

rests on the observation that resources are limited, and that growing populations could rapidly outstrip the provision of resources including land and food

34
Q

risk society

A

the way society organizes itself in response to risk

35
Q

two types of innovation needed for food security

A

capital intenive and labor intensive

36
Q

gmo

A

genetically modified organism: genes from another species

37
Q

pros to gmos

A

more nutritious, better growth, use nutrients more effectively, require less water, heat resistant, faster than selective breeding

38
Q

cons to gmos

A

allergens, environmental impacts, regulatory agencies needed, ethics, hysteria with the “GMO” label

39
Q

success of the GMO tech

A

modest and contreversial: metabolic havoc from switching genes, early choices were purely profit driven

40
Q

CRISPR - Cas 9

A

initial successes: can edit all 3 alleles which can make bread resistent to mildew and wheat crops resistent to drought, gene editing preserces genetic diversity

41
Q

GECs

A

precise editing of organisms native genome rather than another species

42
Q

benefits of microbes

A

1) lock in soil nutrients
2) protect plants from pests

difference between GMO and GEC

A

GECs work within the genome of the original plant

55

synthetic biology

A

-a more sustainable way to produce things like building materials, flavorings, and biofuels

-using micro organisms that can replace industrial processes

-can make food take up less resources

56
Q

precision fermentation

A

genetic modification and fermentation of micro-organisms to create organic molecules. important tool in decreasing food insecurity

57
Q

how can labor intensive ag boost food production?

A

1) good marginal return
2) farmers using nature as a tool to boost production

58
Q

working against labor intesive ag:

A

1) considered backwards
2) low income countries dont invest a lot in ag
3) high income focus research dollars into capital intensive farms rather than actually enhancing productivity of small farms

59
Q

labor intensive farming in vietnam

A

improving smaller hold ag in order to slow rural to urban transition

60
Q

agroforestry

A

the intentional integration of trees and shrubs into crop and animal farming systems to create environmental, economic, and social benefits

ex) planting forage trees for goats, non traditional animals that can be raised sustainably in a forest

61
Q

alley cropping

A

an agroforestry practice that places trees within agricultural cropland systems

62
Q

factors working in favor of organic farmers in high income countries

A

1) consumers in charge
2) fresh produce on the rise
3) health and nutrition = market drivers
4) companies in the food space will be rebranding for health as the antodote to big pharma

63
Q

things organic farmers need to do in order to succeed

A

1) minimize outside impacts
2) long term soil fertility
3) bee friendly farms and soil microbe farms
4) stagger plantings to extend growing season
5) planting diversity of crops that allow you to better attract and maintain customer base

64
Q

business considerations for organic farmers

A

1) shortening supply chain by cutting middle man
2) manage soil fertility for long term
3) adding value to produce
4) include agritourism when feasible

65
Q

societal actions to support organic famers

A

1)strategically placed farmers markets
2) oppurtunities for farmers at park and ride lots
