Two hypothesis about the impact of subsidies to irrigation systems over the land cultivation form. The case of Alto Chicamocha (Boyaca, Colombia)

The article proofs a traditionalist hypothesis based upon arguments such as public investment to congeal the rural-urban dynamics or retaining rural population linked to the exploitation of smallholding rural systems and also proofs a modernist hypothesis based upon concepts such as social necessary work, social costs, effective demand and factors mobility. Finally the article combines its critics with a case data taken from the Alto Chicamocha, Boyaca, Colombia's zone (which measures before 1999, 2001 and 2010) and so falsifies the traditionalist hypothesis and validates the modernist, formulating some conclusions and recommendations.
