Industria y concentración de cultivosla contribución de la industria del frío en la fruticultura leridana

Resumen

In order to move forward in spatial crop concentration, we have chosen apple, pear and peach in Lleida, from 1962 to year 2000. We have supposed that agglomeration causes are similar in these crops, due to production technology and their surfaces. The believed crops agglomeration in Lleida has been explained by an income classification. Evolution of this phenomenon has been studied by spatial equilibrium methods and shift-share analysis, and we have found that there exists a spatial behaviour guide which is different between apple and pear and peach on the other hand. In shift-share analysis differential effect has been modelled as null sum game, and supposing that interchange of effects is more probable between near regions, we have advanced one explanation about surfaces trade off. Crops have showed different spatial behaviours. These differences have been attributed to their aptitude for being preserved in cold-storage. A model has been developed in order to relate cold increases with surface increases in Lleida.
