Lifestyles - identification and quantificationThe environmental impact of an human on earth is mediated by two factors; lifestyle and technological development. Any sustainable transition will probably require changes in both. In our work we attempt to quantify the temporal evolution of several lifestyle dimensions (e.g., diets, consumption) and evaluate the associated environmental consequences.
Dietary habits and food wasteUsing past data from authoritative sources like FAO and a clustering routine, we identified the occurrence of changes in global dietary patterns has occurred during the last 50 years (Pradhan et al. 2013). In addition, future dietary changes have been estimated and future food demand quantified (Pradhan et al. 2013, Pradhan et al. 2013a).
A solution to meet the increasing food demand is to reduce food loss and waste. We determined country scale food availability and requirement ratio as a function of Human Development Index (HDI) for the year 2010. The ratio below 1 represents food deficit. The country populations in billion (bn) and million (mn) are depicted by the diameter of the bubbles (Hiç et al. 2016).
