I am working on my master thesis dissertation for which I need a time series data on food security in Turkey (from 2000 until the the most recent available year) as a single variable. I searched the organizations working for food security, nutrition and hunger such as FAO, WFP, UNICEF and etc., they all have some data which is impracticable in my case for various reasons: it is on a household level, individual level, only focused on nutrition, only food production, only food import/export/prices, and etc.
In addition, I checked out some papers written on food security but was unable to find a way, I looked into World Bank Database I was unable to retrieve any data related to food security in Turkey as a single variable. I need a national level (not HH or individual), single variable, maybe an index or something. Please, help me out!
