Desert safer, OK travelling (7)
I believe the answer is:
forsake
'desert' is the definition.
(I know that desert can be written as forsake)
'safer ok travelling' is the wordplay.
'travelling' indicates anagramming the letters.
'safer'+'ok'='saferok'
'saferok' with letters rearranged gives 'FORSAKE'.
(Other definitions for forsake that I've seen before include "Give up" , "Leave in the lurch" , "'Abandon, desert (7)'" , "Abondon or renounce" .)
