Lecture 10/05 Flashcards
How do we decrease the yield gap?
defensive technologies to protect the yield
-increasing yield potential
-reducing waste
-changing diets in moderation
Positives of green revolution
the crossing of short stiff wheat with the best wheats from mexico alleviated the scarity of food
Negatives of green revolution
environmental harm and overexploiting of farmland and agriculture
-food waste
-overexploitation of the soil
Conservation farming
farming systems that permits minimum soil disturbance, maintenance of soil covered and divsericiation of plant species
3 principles of conservation farming
-minimun mehcanical soil distrubance
-permanent organic soil cover
-species dicersification
Organic agriculture
System that relied on ecosystem management rather than external agricultural inputs
-very minimum external inputs from agricultural end
Transgenic plants
genetically modified
Possible uses of transgenic plants
extending the reproduction time period
-annual to perennial
-plants can survive harsher conditions
Negative uses of transgenic plants
could bring nee allergens into food that people are sensitive to
How does agriculture in WI alleviate some prevalent health problems
High glucan in oats and increased fiber intake for the consumer
Orange maize with beta carotene, so people are getting extra vitamin A
What are the5 research programs of CIMMYT
Sustainable agrifood systems
Wheat
Maize
Dryland Crops
Genetic resources
CoCA: Cost of Calorie Adequacy
Minimum cost to meet energy requirements using the least cost available starchy staple food in each country
-0.79
CoNA: Cost of nutrient adequacy
Minimum cost to meet energy and nutrient requirements
- 2.34
CoRD: cost of recommended diet
Minimum cost to meet food based dietary guidelines, based on food group classifications

Vitamin A deficiency
night blindness, corrneal scarring
Vitamin A foods
meat and vegtables
Iron
red meat, fish, poultry
lentils, beans, leafy vegetables
Zinc
oysters and animal proteins
beans, nuts, whole grains
Efforts to alleviate malnutrition
supplementation- pills
micronutrients in staple foods
equal or better agronomic performace of biofortified crops
Effects of prridge preparation
25% loss of beta carotene
Why is agriculture important for development
Agriculture generates ave 29% of GDP
Agriculture employs 65% of labor workforce
Increase access to assets
Household assets determine the ability to participate in this progression out from poverty
Increasing assets may require affirmative action to include disadvantaged groups
Assets: land, water, education, health
