This open access book provides a panoramic view of the evolution of
Spanish agriculture from 1900 to the present, offering a more diverse
picture to the complex and multidimensional reality of agrarian
production. With a clear transdisciplinary ambition, the book applies an
original and innovative theoretical and methodological tool, termed
Agrarian Social Metabolism, combining Social Metabolism with an
agroecological perspective. This integrative analysis is especially
interesting for environmental scientists and policy makers being the
best way to design sustainable agroecosystems and public policies
capable of moving us towards a more sustainable food system.
Spanish agricultural production has experienced impressive growth during
the 20th century which has allowed it to ensure the supply of food to
the population and even to transform some crops into important chapters
in foreign trade. However, this growth has had its negative side since
it was based on the injection of large amounts of external energy, on
the destruction of employment and the loss of profitability of
agricultural activity. But perhaps the most serious part is the strong
impact of the current industrialised agriculture model on Spanish
agroecosystems, exposed to the overexploitation of hydric resources,
pollution of the water by nitrates and pesticides, high erosion rates
and an alarming loss of biodiversity; damage which in the immediate
future will end up reducing production capacity.
