§.^ The surveys producing these world rankings have been done in different times and might not be current. Please refer to the specific articles or sources for updated information, where available.

It should also be noted that the rankings are based on surveys by numerous entities with different benchmarks and standards, thus caution is needed in their interpretation of final results specially in the case of subjective field matters, as some of these rankings maybe based on speculative, biased, subjective or politicized evaluations. Finally, it is always important to consider trend when making comparisons, since single point data may be exceptional in nature (e.g. Iran's 2008 drought and wheat production).
