Jumping straight into scholarly literature when you don't know a lot about a topic can be overwhelming. Spending a little time beforehand learning about the situation and issues involved can save you time and lead you to scholarly sources.
Search Google with site:.org OR site:.gov. for groups working on your issue or who is responsible for implementing policies for it
You can also search large NGO sites more easily this way: site:fao.org
Once you have some background, search Google Scholar for a good review article
