What does Chile do to protect its agriculture?

They set policies in place in order to protect small farmers, large exporters of crops, and also the crops themselves.

Agriculture is one of the main economic activities in Chile, accounting for 28% of the country's total trade and 11% of its total GDP. Approximately 10% of the country's labor force is engaged in agriculture and related services. Chile's economy is driven by exports, concentrated primarily in copper and its agricultural sectors: fresh fruit, forestry and fishery products. The agriculture sector is projected to grow by approximately 5% in 2019 (above the country's economic projected growth of 3.0%) according to SNA, Chile's National Agriculture Society. After the sector's impressive growth by 9.5% in 2015, and 3.7% in 2016, the industry dropped to 2.5% in 2017, mainly due to low production of livestock and poultry, and low crop production, especially corn. However, agriculture recuperated growing by 5.8% in 2018, becoming the fastest growing sector. Chile is the world's largest exporter of fresh table grapes, blueberries, prunes, dehydrated apples, and frozen salmon fillets.
