In the sentence could is used as an auxiliary verb: "could" expresses a possibility, an hypothetical situation, we don't have a necessity to use "could" though.
The other answer have errors:

Even though sub-Saharan Africa often evokes images of drought and famine, researchers say that the area is the home of more than 2,000 grains, vegetables, roots, fruits, and other foods that have the possibility for feeding the continent, even other parts of the world.

A and B use a wrong idiom "have the possibility of/ for".
E is redundant: as I said before "could" expresses a possibility and "could possibly" is redundant.
In addition E is not parallel : "feed the continent and (...) for even".

(C) could feed the continent, so even with other parts of the world. Structure issue, and not parallel
(D) could feed the continent and even other parts of the world. Parallel and clear

It is important to recall that "could feed"is not past tense exactly. It's a future"hope" .
For example consider the sentence - "I am wealthy. I could/should help the poor."
The word could/should is a hopeful future tense and not past tense, but makes perfect grammar & sense. I'm not 100 percent sure what these are called, but it's similar to the conditional Clauses - " if I were a bird, I would fly" which also seems to have two different tense forms, but is grammatically correct.

Hope it helps!

SO can you point some differences when to use can and could?

To be honest, they are both correct! But the word 'could' is more 'respect-giving'. Lets take a few examples :-

When talking to your best friend, we'd rather say - " I can do it". But when talking to an elder/respected person, we'd rather say -" I could do it"

In the same way, if you ask permission to a KING or someone higher above, the more correct way to ask would be - "Could I do it my LORD?" rather than "Can I do it my LORD?"

A few more examples:-

"May I come in Teacher?" vs "Might I come in Teacher?" - Both are the same in terms of grammar & meaning. But 'Might' is just very more humble/respect-giving.

Hope it helps! :)

Even though sub-Saharan Africa often evokes images of drought and famine, researchers say that the area is the home of more than 2,000 grains, vegetables, roots, fruits, and other foods that have the possibility for feeding the continent, even other parts of the world.

(A) have the possibility for feeding the continent, even - "have the possibility of..." is an unidiomatic construction
(B) have the possibility of feeding the continent, even of - same as A
(C) could feed the continent, so even with - parallelism issue - "with" isn't parallel to anything in the other part of the sentence ; Run on - (c) is not grammatically a sentence; if you use "so" as a conjunction, it should be followed by an independent clause (i.e., another complete sentence)
(D) could feed the continent and even - Correct
(E) could possibly feed the continent and, in addition, for even - parallelism issue - "for" isn't parallel to anything in the other part of the sentence ; also has two instances of redundancy:
could + possibly
and + in addition

Answer D
