Forest gardens are probably the world's oldest and most resilient agroecosystem. [4] Some major organizations are hailing farming within agroecosystems as the way forward for mainstream agriculture. Current farming methods have resulted in over-stretched water resources, high levels of erosion and reduced soil fertility.
Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output ...
The following list, derived from the statistics of the United Nations' Food and Agriculture Organization (FAO), lists the most valuable agricultural products produced by the countries of the world. [1] The data in this article, unless otherwise noted, was reported for 2016.

Today's land grabbing activities are often a consequence of the strive for agricultural land by growing economies. [6]
The amount of agricultural land covered by this is 453 million ha of land. That amount of land is equal to 29% of farms worldwide.
