A wicked problem is defined as having “no stopping rules,” as well as being a “symptom of another problem” (Rittel, 1973). According to the World Health Organization (2014), food security is based on three pillars: food availability, access to food and use of food. This means that the problem is multi-causal, as it relies on sufficient quantities of food, sufficient resources to obtain appropriate foods, and appropriate use. Food security can be seen as a wicked problem, because it has no stopping rules as it can be linked to natural resource depletion and climate change and is therefore multi-causal. The European Commission believes that the problem will worsen due to the expected 70% increase in food demand by 2050, as a result of population growth and changing diets (Freibauer, et. al. 2011). The main problem of population growth is the question of balance between population and land surface. The Earth's surface is not entirely fixed but does not vary much with respect to time scale. (UN, 2004) According to the United Nations Department of Economic and Social Affairs (2004), 99% of the projected increase in the world's population will occur in less developed regions, and because less developed areas have less access to technology, the food security will decline. be further decreased. (Monsanto, 2014). Climate change impacts food systems through agricultural production. Changes in precipitation, which can lead to drought or floods, will impact production (availability of food). This will have further effects on markets as food prices change (access to food). (Gregory et. al. 2005). However, there are some doubts about whether climate change is actually happening.
