Studies made by the Swiss politician Jean Ziegler show that the world agricultural system is able to feed twice the population of the planet. However, 800 million people are hungry. During the last years, the Colombian Government has been designing policies oriented to provide solutions to the hunger problem and thus to decrease the number of Colombian families which lack this fundamental right, the food supply. However, the effects of these policies have not been the expected ones, on the contrary, lower class people is still plunged into poverty and hunger. Why have they not been effective? Which have been the consequences of implementing those policies? Considering the impact of economic liberalization during the 90ís on the agricultural sector, a model has been constructed taking into account the national production, the cultivated area, the people working and the capital invested on the agricultural process. The simulation results of the implementation of the commerce liberalization policies seem to match with the results recorded in the Agricultural and Rural development Ministry. Finally, the model will be tested in a scenario that includes the policies that are part of the Development Plan proposed by the current Government 2002-2006 to observe possible consequences of this implementation.
