Marine Ventures ou adaptação das sociedades humanas a frentes oceânicas e ribeirinhas no tempo longo e à escala global


Foi este o tema do Simpósio Internacional que decorreu em Trondheim (Noruega) de 2 a 6 de Outubro/2013.
O MAEDS fez jus à nossa cultura marítima, fazendo-se representar através da comunicação: Rethinking the Mesolithic of the Sado Paleo‐Estuary (Portugal). Semi‐sedentary hunter‐gatherers, por Joaquina Soares.

The author presents a synthesis about the Mesolithic of the Sado palaeoestuary, building a model of socio-economic dynamics in a long-term perspective, and in the wider context of the neolithization in Southern Portugal. At the time span of 5700–4500 cal BC, when the adoption of agriculture and domestic animals took place, two major lifestyles coexisted in the South of Portugal:
1) Coastal-adapted hunting-fishing-gathering societies, which developed “high” degrees of sedentism and a correlated increasing population density – ecological/demographic imbalance. This trend required an intensification of the Mesolithic broad-spectrum economy, with the earliest adoption of domestic species. The new food resources have been integrated in the traditional subsistence system, achieving a typical mixed economy;
2) Affluent foragers organised in a demographic equilibrium sustained by a richer set of natural resources in the Tejo and Sado estuaries, avoiding to adopt the food-production economy, they kept for about one thousand years their Mesolithic hunting-fishing-gathering economy, with storage. Among these groups, only the ceramic containers, from the “Neolithic package”, had been adopted (according to its vantages for storage) during the evolved Early Neolithic (transition and first half of the V millennium cal BC).
