 Chile's extreme north–south orientation produces seven different macro-regions distinguished by climate and geographical features, which allows the country itself to stagger harvests and results in extended harvesting seasons.However, the mountainous landscape of Chile limits the extent and intensity of agriculture so that arable land corresponds only to 2.62% of the total territory.Through Chile's trade agreements, its agricultural products have gained access to a market controlling 77% of the world's GDP and by approximately 2012, 74% of Chilean agribusiness exports will be duty-free.
