This table shows the change in agriculture in Asia by the end of the 20th century when 70% of wheat areas and 74% of rice areas were sown with HYVs.
1 Fast adoption by farmers with plentiful land and/ or money. Land is used as security to buy seeds, irrigation pumps, fertilisers, pesticides, HYVs and so on, hence small farmers cannot benefit at first.
2 Adoption by smaller farms caused by: government- backed agricultural development projects, new seeds targeted for more environments and continued population pressure creating extra demand for more food.
3 Diffusion of new techniques to most farmers. Widespread adoption.
