  abstract = {{T}he agricultural rehabilitation of tepetates, indurated and sterile volcanic tuffs located along the mexican neovolcanic ridge, is technically possible. {H}owever, it is necessary to know in detail the agro-socioeconomical factors of the peasant communities which have these kind of lands, to give them technical answers appropiate to local realities. {T}he studies of 4 communities located in the states of {M}exico. {T}laxcala, {J}alisco and {M}ichoacan, show that the climatic conditions are mostly difficult (long dry season, irregular rains, early frosts). {T}he use of irrigation is limited. {E}ach producer family cultivates a small surface of land which is principally ejidal. {T}epetates areas are the last pieces of land still not distributed and of common use (firewood ans pasture).{M}ost peasants can survive with the help of an external job, while field production is mainly for self-consumption. {D}uring the last 20 years, capitalisation occured through the purchase of cattle. {S}o, the number of animals is growing up and by consequence, the pressure on the natural pastures too, favouring the apparition and extension of tepetates. {B}reaking the tepetates to give them a new agricultural use means, in addition to technical help at the beginning, the creation and development of forage crops. {A}ctually, this type of crops are not very common. {I}t is also necessary to propose forest management and/or wood-fire plantations. {T}he costs of this rehabilitation are too high (nearly 1,000 $/ha) for most peasants, in spite of the increasing value of the land after this work and a recuperation of the investment after 5 and 8 years in the production systems which use animal and mechanical tractions. {S}o those investments require external help ({S}tate, {NGO}s, credits...) at the beginning.
