How did global agricultural economy take …

(i) Food and other products : Food and Other products started flowing from far away places. It was no longer grown by a peasant tilling his own land, but by an agricultural worker, perhaps recently arrived, who was now working on a large farm that only a generation ago. had perhaps been a forest.
(ii) Infrastructure : The food and other products being transported by railways bud: for that very purpose and by ships which were increasingly manned in these decades by low paid workers from southern Europe Asia Africa and the Caribbean Islands.
(iii) Raw materials : Indian farmers were producing raw cotton and other farm products to British industry. World trade between 1820 and 1914 multiplied about 25 to 40 times.
(iv) Scrapping of Corn Law : The scrapping of the Corn Laws laid the foundation of free trade. Now food could be imported or exported into Britain freely.
(v) Commercialisation of agriculture in colonies: The imperial countries took various steps to commercialise agriculture in their colonies. For example. British government built a network of irrigation canals to transform semi desert waste land of West Punjab into fertile agricultural land.
