Deforestation is one of the greatest contributers to soil errosion. Without tree roots firmly forming a matrix to stabalize the soil land erodes from slopes and hills. What soil remains is left to the mercy of the wind and rain, and this eroding soil drags everything it encounters down with it. <ref> Lopex, Laura. L., Esteva, Gustavo., Consejo, Juan J., Padilla, Eugenio., Robles, Marcela., and Alejandre, Virginia. Defensa Ecologica: Manual de Tecnicas.  2a. edition. Oaxaca, 1998. </ref> In Oaxaca as well as other places in Mexico campesinos (or small farmers) have been pushed off their land and often find that the only avialable land left for their small farm is on forested slopes. For this reason Petegral wanted to create a center that demonstrated different applications of farming on steeply sloped hills previously deforested. Some of their techniques demonstrated include: terraces, ditches, buffers of perrenial grasses, and mixed or polyculture planting.
