Pratiques et stratégies de gestion des ressources herbagères cultivées par des éleveurs laitiers sur un front pionnier en Amazonie brésilienne : cas du municipe de Uruar

Abstract : In the Brazilian Amazon frontiers, milk production is an important component for smallholders' viability. In dairy farms, herd feeding is based on cultivated pasture established after forest burning. Pasture degradation is considered as a constraint for farms' sustainability. The objective of our approach is to identify the role of pasture perenniality to consolidate and stabilize
dairy farms. This research deals with the case of dairy farmers in the Uruará municipio situated on the Transamazonian frontier region in the state of Pará. The analysis of livestock farming system' diversity, on the basis of agricultural structures and farms' evolution, shows different functions allocated to milk production and dynamics of change. The analysis of combinations of farmers' practises, on the basis of farms continuous surveys for
one year, shows four major pasture management strategies characterized by practises (modalities and decisions), determinants and reasons. Theses results allow to identify farmers' objectives and capacities to manage pasture. In Brazilian Amazon, pasture perenniality is not the only stake and not the major constraint for
dairy farms' sustainability and reproducibility. It's necessary to adapt approaches and proposing solutions to pasture management in order to ensure smallholders farming system' sustainability and
forest preservation
