Below are some searches for peer-reviewed journals that might be useful as a starting point. The ONESearch Guide tab will help you learn how to refine your searches and can further explain the features I used, beyond the brief explanations below.
Drone* AND planning
The asterisk (*) will match zero or more characters within a word or at the end of a word. When used at the end of a word, the asterisk will allow all possible characters to be included so Temp* will match Temptation, Temple, and Temporary.
I used 'AND' to be sure both terms would be in the results.
I used quotes around phrases to be sure the words would be found as noted in the "", such as "climate change".
