an agro-economic quiz

Post  WillyNilly on Sat Nov 17, 2012 2:48 am

the countries with the top ten arable land areas in the world are given below. also given are their total land areas. neither the arable areas nor the total areas are arranged in the same order as the countries; for example, the 850 and 61 units of land in the first line do not belong to argentina. areas are in millions of hectares.

match the country to the arable land area by simply typing in the line/country number to the right of the arable area. each correct match gets you one point.

for your general info, 1 hectare = 10,000 sq m = 0.01 sq km = 0.003861 sq mi = 2.471 acres.

if more than 100 members participate, i shall not calculate the scores. i'll post the correct answers by 4:00 pm cst on monday.

no googling, please.

country-----total land area-------arable land area

01. argentina --- 850 ----------------- 61
02. australia --- 1645 ---------------- 122
03. brazil ------- 297 ---------------- 158
04. canada ----- 932 ---------------- 110
05. china ------- 902 ---------------- 45
06. india --------- 57 ---------------- 32
07. nigeria -------916 ---------------- 163
08. russia ------- 773 ----------------- 47
09. ukraine ------ 274 ----------------- 31
10. u.s.a. -------- 91 ----------- ----- 34

For me Russia (second row) has the largest land area. The numbers at the extreme left are *not* representing anything other than row number. I did not sort the rows as I should have.

the problem was to rank the countries by arable land area.

i'm sorry i missed my deadline; i was too busy yesterday to post the answers. they are shown on the right side of the table below.

the ranks are shown on the extreme right, and the country, immediately to the left of the rank, i.e. in the penultimate column. the area data remain correct for the countries on the right.

country-----total land area-------arable land area

01. argentina --- 850 ----------------- 61 -- brazil 5
02. australia --- 1645 ---------------- 122 -- russia 3
03. brazil ------- 297 ---------------- 158 -- india 2
04. canada ----- 932 ---------------- 110 -- china 4
05. china ------- 902 ---------------- 45 -- canada 7
06. india --------- 57 ---------------- 32 -- ukraine 9
07. nigeria -------916 ---------------- 163 -- u.s.a. 1
08. russia ------- 773 ----------------- 47 -- australia 6
09. ukraine ------ 274 ----------------- 31 -- argentina 10
10. u.s.a. -------- 91 ----------- ----- 34 -- nigeria 8

as you can see, u.s.a., india, and russia, in that order, have the largest arable land areas; india's arable area is close to u.s.a.'s even though india's total area is less than one-third u.s.a.'s.

the % of total area that's arable varies vastly from country to country; for india, it is 53%, while for u.s.a., it is 18%. the lowest among the ten is canada's, at 5%. i wonder why it's so low. is it because much of canada is uncultivable because of the cold temperatures and snow?

rashmun got three matches; that's excellent. he was not far wrong on the others; he could have got over five matches if he had interchanged a few countries he had given adjacent ranks to.

in canada only the regions relatively close to the u.s. border are arable.

i mentioned the fact of u.s. being number 1 and india being number 2 in terms of arable land area to some caucasian americans at work and they were very impressed. one of them told me (in jest) 'together we will rule the world.'
