The global increase in population growth by 34 %, which is estimated to reach an overall number of 9.1 billion people by 2050, raises the demand of food products by 70 % (FAO 2009). Assuming a geometrical increase in the world’s population, everincreasing amounts of arable land, water, energy, and biological resources will be required to meet the current and future demand for food products. The complex interaction between food production and the natural environment is mentioned in the literature on food networks. (Bertalanffy 1950, Leischow and Milstein 2006, Sobal, Kettel Khan and Bisogni 1998)
