Changing dietary habits may be creating an unhealthy dependence on crop pollinators, which could lead to a global food shortage. That’s the verdict of a new collaborative study between the United States and Germany, which looked at how trends in farming practices over the last half century are affecting the insects which pollinate crops, the use of land and the future of food security. Their findings show that there has been a gradual shift away from staple crops which do not require pollination – such as corn, rice, soybeans and wheat – in favour of luxury ones which do, such as almonds, avocado, citrus fruits and coffee. As a result, more land is being occupied by less urgent crops which place greater demands on nature, thus jeopardising our food sources in an uncertain future. Agricultural ordeals Much of the debate surrounding farming focuses on the relationship between agriculture and water , as well as the amount of land being devoted to crop cultivation. While these are legitimate concerns which deserve attention, less research has been undertaken into how crop varieties may have a significant impact upon the conversation, especially those which require pollination. Keen to rectify this wrong, scientists […]
