ARAMAYO BAZZETTI, Armando  e  SANCHEZ INFANTAS, Edgar. Determining collapse phases in the different stages of the environmental history evolution of Cerro de Pasco (1901-2008). Ecol. apl. [online]. 2010, vol.9, n.2, pp.113-124. ISSN 1726-2216.

The present study analyzes the city of Cerro de Pasco since the arrival of Cerro de Pasco Investment Company (afterwards named Cerro de Pasco Copper Corporation) in 1901 up to the year 2008. Using the adaptive cycles, whose operational instrument is the analysis of the different capitals (which are the stocks a systems has, such as physical, natural, social, human, political and financial or economic), one complete cycle has been determined and an almost complete second one. The first one of these starts with the collapse of the local mining and the falling prices of silver, which gives the impulse for the entrance of big mining into the region. The identification of the collapse phases (Ω) is done by the analysis of six different capitals which have been taken into account. Each one of those is at the same time a microcycle and when several of them have entered that collapse phase, it means that the complete system would be entering the collapse phase, which means that the whole system is entering a period of decomposition before reorganizing and starting a new period or cycle. The proposal in the present study can be used to identify the different cycles in a more conclusive manner.
