ikenai construct
Good Question - this one had me stumped for while when I was learning.

~nakya ikenai is a casual and compressed way of saying ~nai to ikenai. Another
version you frequently hear is ~nakucha ikenai. You won't see the ~nakya or
~nakucha construct in writing or in formal speech.

And just for clarification: all those constructs mean "have to verb".

> shukudai wo yara **nakya** ikenai
>
> shukudai wo yara **nakucha** ikenai
>
> shukudai wo yara **nai to** ikenai

All mean "I have to do my homework". The bolded parts are interchangeable
without altering the meaning.

answer
-nakya is a shortened form of -nakereba, which is the negative conditional ("If it doesn't happen").

-nakereba ikenai / -nakereba naranai is a specific construct that essentially means "must" (it kind of translates to "it's forbidden to have not done").

So the fragment you have here translates to something like "When there are
things you absolutely must do ..."
