The Global Food System: I-Definition of a space

About This Project

 The global food system: I – Definition of a space.

 

The authors develop their model of global food system, presented in earlier publications, based on four basic axes (availability, economy, politics and knowledge) giving  it an understandable open structure, and applying a mathematical methodology which permits the knowledge of the evolution of the parameters and its prospects.

 

To this end, this current study goes beyond qualitative concepts to quantitative ones. Each axis is broken down into three sub-axes giving a total of 12,  that identify the specific aspects of the primary ones and define the fundamental activities and concepts of the food system in this space and in such a way that their contents can be developed further in even greater detail, in a fractal development on a tetrahedral base.

 

A first evaluation parameter is proposed for each sub-axis based on values in units, that can be obtained, time units, years usually, from reliable published data and compatible with the model of evolutionary and prospective studies presented in which a variable vector for each axis is proposed that takes values in the simplex of three parts and adjusted to a lineal model in ILR (isometric log ratio transformation) coordinates. The model standardises a structure that highlights the global food area and allows prospective strategies to be carried out on the same subject, on each parameter or between them.
