AGR 1110 final exam questions well
answered graded A+
What is subsistence agriculture - correct answer ✔✔Farmers grow only enough food to feed
their families.
Ha to Acres - correct answer ✔✔1 Ha= 100m x 100m = 2.5 acre
100 Ha= 1km x 1km (avg Ontario farm size) = 90 Ha= 220 Acres
Implications of being a farmer with less than 2 Ha - correct answer ✔✔For a 2Ha farm: at 5000
healthy corn plants/ acre x 5 acres = 25,000 corn plants
25,000 corn cobs= 4 corn cobs/ meal x 3 meals/day for a family of 6
Corn- fed cattle needs? 8kg/day x 100 days for 14 kg weight gain= 2200 ears required (10% of
family corn)
Sell extra? US $5/bushel= $5/25kg of shelled corn = 70 ears = 7 cents/ ear
Implications for tax revenue- if family can sell 10,000 cobs/ year and the tax rate is 15%. Then 1
cent/cob of tax = $100 per family
Uganda tax implications - correct answer ✔✔Population is 43 million people, and 9 million
people farm
Only $900 million in tax revenue to build roads, schools, healthcare
Uganda's federal budget is $10.8 billion compared to Canadas $330 billion CAD federal budget
Humans evolved in Africa
Consequences - correct answer ✔✔Anatomically modern humans (AMH) evolved in east Africa
2 million years ago
, 1.We are all African
1.There is more genetic diversity in Africa than any other continent
2.There are over 2000 languages in Africa
2.Nigeria alone has 250 living languages
3.Disease pathogens can jump from primates to humans which are 99% genetically similar
African and African nations are huge - correct answer ✔✔Most African nations are the size of
Ontario or larger: ON and QC - DR Congo or former Sudan
3 Canada's = 1 Africa
Consequence:
1.Is Africa over- populated: we don't call Japan or European nations overcrowded so why do we
call African nations?
2. there is the potential for a lot of arable land and pastureland for grazing- Africa has 733
million hectares of arable land with only 17% of the world's population
Africa is the only continent to be dead center with respect to the equator - correct answer
✔✔Consequence: middle of Africa is too wet, and the top and bottom of Africa are too dry
Soils- top: Sahara desert bottom: Kalahari desert
What are the consequences of too much rain for agriculture? - correct answer ✔✔Issues with
human livestock, soils, post- harvest storage
Too much rain also allows insects to reproduce and spread disease
Many people are located where there is a good year-round temp and water supply especially in
West Africa - correct answer ✔✔Nigeria is the most populated country in sub-Saharan Africa
with a population of 140 million people
West Africa (Nigeria, Cameroun, Ghana, Cote d'Ivoire, Senegal etc) has a pop of > 250 mil
