[Rural emigration in the inter-Andean valleys of Bolivia].

Inscribed within an ancient national tradition rural emigration in the interandean valleys of Bolivia is gaining importance. The countrys contemporary crises and the immigration policies of the host countries maintain the flux trend towards Argentina while enabling new destination targets: the United States and more recently Israel and Japan. In these Bolivian lands the emigration derived income provides the driving force of family economies and triggers development of the local territory. At the same time emigration induces a process of socio-economic differentiation in peasant communities which weakens the food-system and increases family nutritional risks in the populations marginal to this migration system. In addition to these mutations there is a strong sociocultural destructuring which affects community-cohesion in local societies. (SUMMARY IN ENG AND SPA) (EXCERPT)
