Desde hace dos o tres décadas, los sistemas alimentarios en Latinoamérica atraviesan un período de transición en el que ha aumentado el consumo de productos procesados y agroindustriales tanto en zonas urbanas como rurales, lo cual nos anticipa a una nueva cultura alimentaria asociada a modelos vigentes de producción, distribución y consumo que perjudican sobre todo a pequeños agricultores familiares. Igualmente en el contexto de la nueva ruralidad, los hogares rurales son más móviles y ocupan su tiempo en más actividades, por lo que las decisiones, estrategias y dinámicas familiares alrededor de la alimentación han cambiado. En tal escenario, esta tesis busca comprender el sistema alimentario de unidades domésticas (SAUD) que practican la agricultura familiar de subsistencia en la isla Amantaní (Lago Titicaca) y explicar sus principales transformaciones en las dos últimas...

Drawing on two studies and surveys carried out in the Upper Huallaga in 1981 and the VRAE in 2001, both located in the upper Peruvian amazon basin, this paper seeks to describe and analyze the historical and economic conditions under which coca cultivation for illicit purposes expanded in both regions. In this sense, it describes how this history shaped an inefficient and destructive migratory agriculture. Although the periods analyzed in each case are different, with a difference of twenty years between one and the other, the information we have is sufficiently valuable to establish a useful and valuable comparison. These are the two Amazonian regions that had the largest extension of coca plantations at the national level during the study period. When coca expanded in the Upper Huallaga, there was already a much more intense social and economic history of articulation with the market a...
