Del manejo multifuncional del territorio a la desarticulación productiva: cambios en los flujos de biomasa durante el proceso de industrialización de la agricultura gallega (1960-2012)

This paper offers an annual series of plant biomass in Galicia during the period 1960-2012. The timeframe chosen encompasses the final period of the organic agrarian system, the consequences of the industrialisation of Galician agriculture, and the impact of Spain’s integration into the European Union. The paper provides several indicators regularly used in the biophysical analysis of agriculture such as the Domestic Extraction of Biomass, and its division into Socialised Biomass and Reutilised Biomass. Furthermore, data regarding livestock production are also provided along with a series of livestock feed requirements. The findings show an accelerated transformation since the 1970s away from a model in which the majority of biomass flows were allocated to the reproduction of agroecosystems, moving towards a model in which Socialised Biomass is maximised. This shift towards closer ties with the market, however, has turned Galicia into a food dependent region that is also dependent on abiotic (fertilisers, energy) and biotic external inputs (livestock feed). This transformation has had consequences in terms of sustainability and the economic viability of the agrarian sector in this region.
