Une approche pour évaluer la vulnérabilité des systèmes d’élevage laitiers selon leurs trajectoires de développement : le cas des agriculteurs familiaux d’Unaí – Brésil

Abstract : Small dairy farmers face many challenges and risks in developing their production systems, in a highly unpredictable environment marked by uncertainties in climate and market, for example. But the challenges and risks are even greater when they develop their system from scratch (ex nihilo), a common situation in agricultural frontier areas and in the context of land reform in Brazil. Three main concepts are used to assess the dynamics and adaptability of systems, depending on the objectives : resilience , flexibility and vulnerability. This thesis presents the concept of vulnerability related to trajectories of development, as it was applied to assess 24 smallholder farming systems in the region of Unaí (Minas Gerais, Brazil). We propose a framework to evaluate the vulnerability of milk production systems, based on 10 indicators derived from the types of “difficulties” faced along the farm development trajectory as identified by smallholder farmers. These 10 indicators relate to three key dimensions of a trajectory : the family dimension (3 indicators), the technical dimension (4 indicators) and the financial dimension (3 indicators). By comparing values of indicators of vulnerability between different years for the same disturbance (a drought which occurred both in 2007 and 2011), many production systems decreased level of vulnerability over time. There is a great stability of the indicators related to family dimension. The vulnerability of five production systems decreased between 2007 and 2011, but with different amplitudes. A system may be vulnerable to a given disturbance at one moment, not vulnerable at another moment, or vice versa. In the near future, we will present our results to farmers and other actors in the milk production chain in Unaí, with the hope of stimulating discussion among them about the best way to "build" a production system that performs well without increasing the vulnerability of the system.
