According to Nature Climate Change journal, the decline can be equated to a hypothetical total loss of production over past seven years.
Taking into account there are nearly 10 billion people worldwide to feed by 2050, some experts believe it is crucial to stabilize production and enable more dynamic growth.
The study found that anthropogenic or man-made climate change is already having a disproportionate impact on those underdeveloped countries that primarily depend on agriculture.
Scientists strongly recommend to take meteorological data into account when measuring agricultural productivity, as these acquire greater importance in the face of the consequences of climate change.
