"Areas for development". 11a "working capital" suggests the other unclued lights which are all one word anagrams of words of a kind. I just cannot work this out. Hints or advice please.
'working' is an anagram indicator and all of the words are capital cities to begin with (there's nothing connecting the anagrams as such).
To get you started, the plant entered at 23 comes from an African capital - the insect at 2d from an Asian one.
