The history of agriculture in India dates back to the Neolithic period. India ranks second worldwide in farm outputs. As per the Indian economic survey 2020 -21, agriculture employed more than 50% of the Indian workforce and contributed 20.2% to the country's GDP.[1]
In 2016, agriculture and allied sectors like animal husbandry, forestry and fisheries accounted for 17.5% of the GDP (gross domestic product) with about 41.49% of the workforce in 2020.[2][3][4][5] India ranks first in the world with highest net cropped area followed by US and China.[6] The economic contribution of agriculture to India's GDP is steadily declining with the country's broad-based economic growth. Still, agriculture is demographically the broadest economic sector and plays a significant role in the overall socio-economic fabric of India.
The total agriculture commodities export was US$3.50 billion in March - June 2020. India exported $38 billion worth of agricultural products in 2013, making it the seventh-largest agricultural exporter worldwide and the sixth largest net exporter.[7] Most of its agriculture exports serve developing and least developed nations.[7] Indian agricultural/horticultural and processed foods are exported to more than 120 countries, primarily to Japan, Southeast Asia, SAARC countries, the European Union and the United States.[8][9]
Pesticides and fertilizers used in Indian agriculture have helped increase crop productivity, but their unregulated and excessive use has caused different ecosystem and fatal health problems.[10][11] Several studies published between 2011 and 2020 attribute 45 different types of cancers afflicting rural farm workers in India to pesticide usage. The chemicals have been shown to cause DNA damage, hormone disruption, and lead to a weakened immune system.[11] Occupational exposure to pesticides has been identified as a major trigger of the development of cancer.[11] The principal classes of pesticides investigated in relation to their role in intoxication and cancer were insecticides, herbicides, and fungicides.[12][11] Punjab, a state in India, utilises the highest amount of chemical fertilizers in the country. Many of the pesticides sprayed on the state's crops are classified as class I by the World Health Organization because of their acute toxicity and are banned in places around the world, including Europe.[13][14]
