摘要
Less than 1%of the total population of the developing world is positively affected by biotechnological innovation.The global impact of biotechnology on agriculture is impeded by the disproportionate development and growth of economically important crops in the developed world.In over 2 decades,526 genetically engineered events,or bioengineered(BE)traits,in 32 crops have been approved in 44 countries(ISAAA database,2020).Of these 44 countries,38 are high income,representing 73%of the developed world.Just six represent low-income countries,including four in Africa(ISAAA database,2020).Although many countries import BE crops for feed,food,and processing,just over half of the 44 countries cultivate(ISAAA,2017).Twenty years since their development,the acreage used for BE crops has increased from 1.7 million to 191.7 million hectares.This increase in growth is dominated by economically important crops such as cotton,maize,and soybean,which also account for 65%of new traits(Brookes and Barfoot,2018).
