For the analysis of economic interdependences form an environmental perspective, a condensation of the information contained in input-output (IO) tables is desirable, but without much loss of the quantitative dimension. For the case of total energy requirements, main contributions identification...

We apply to the Senegalese input-output matrix of 1990, disaggregated into formal and informal activities, a recently designed structural analytical method (Minimal-Flow-Analysis) which permits to depict the direct and indirect production linkages existing between activities. Our results show...
