A methodological framework for a consistent allocation of environmental burdens related to the consumption and production of biomass between regions has not been put forth to date. The concept of the embodied human appropriation of net primary
production allows for the assessment of the upstream effects on ecosystem energetics associated with a particular level of biomass consumption or with a given biomass-based product. This article puts forward the HANPP concept, illustrates its utility

Economic sector ; Industrial sector ; Industry ; Labour productivity ; Regional economy ; Spain
This article assesses productivity growth across Spanish regions and industries through a production-frontier approach. It is shown that capital deepening is the primary contributor to productivity growth, closely followed by human capital
and technological change. Analysis of sectoral data shows marked differences in productivity performance; and aggregate productivity growth is driven by intra-sectoral productivity dynamics rather than by structural change.
