oil & food: a rising security challenge
As the population is increasing, demands on oil are higher because land productivity is raised. Land productivity is raised by using different ways that require using oil. The demands for oil are high due to the vehicles and machines used on farms. The production of oil or energy is broken down into the following percentages: 28% fertilizer manufacturing, 7% irrigation, 34% farm vehicles. Oil is also used for the following: agricultural production (21%), move (14%), process (16%), package (7%), sell (4%) and store the food (32%) that is produced and sent out from the farm to resturants and supermarkets (7%). The more intensive with energy, the transport of food can help provide fresh foods from other countries. Fresh foods require less work and processed foods does because processed foods has to go through many processes of packaging, which uses more oil. On the other hand, fresh foods require less packaging since they are packaged in a larger amount than processed food is.
