Let us start with an obvious statement. We all need food. That is why politicians and people, in general, are all concerned with food production and we address the issue among others as food security. Food security is one of the 17 Sustainable Development Goals established in 2016. But even before that the G20 recognized the importance of closer monitoring of agriculture and food production. As part of the Action Plan on Food Price Volatility and Agriculture, the G20 Heads of States endorsed in their 2011 Declaration both Global Agricultural Monitoring (GEOGLAM) and the Agricultural Market Information System (AMIS).
