Range management and production on the fringe: The Caldenal, Argentina

North American problems in coming to terms with the management of the semi-arid Plains environment are well known. Less documented are those of Argentina's equivalent on the fringe of the Humid Pampas. Argentine agricultural aid and research has been focussed on the Humid Pampas, and little understanding of the special problems of the dry zone is apparent. Issues of production and conservation are in urgent need of attention. In addition to the limits posed by the natural environment, a number of human factors affect the ability of ranchers to produce from the dry lands. In a field study of the Caldenal, some indications are that the factors are different from other environments in Latin America. Large properties are not less productive per hectare than small, and standard technology does not guarantee good results from ranching. Tenant farming is not a problem, but there is an impoverished group, those ranchers without other means of earning a livelihood. A recommendation is for encouragement to be given to larger ranch units, and for more research into relevant technology, which is likely to include conservationist measures, whose introduction to the ranches should be financially supported.
