A shift in natural resources management paradigm: from resources sufficiency to functional integrity ?
Two standpoints on sustainability in livestock farming According to Thompson ( 1997 ) two philosophical approaches to sustainability in natural resources management have now emerged..Resources sufficiency.stresses the quantitative estimation of available resources and the measurement of rates at which resources are used in production, distribution and consumption of food.With regard to livestock production, the issue is one of increasing efficiencies, reducing pollution and finding substitutes for scarce inputs..Functional integrity stresses the vulnerability that may be associated with current ignorance about the systemic interactions of production practices with processes of ecological and social renewal.It interprets agriculture as a system, which embodies complex and poorly understood value commitments and ecosystem links.It supports policy strategies that emphasize the preservation of capacity for resilience and the avoidance of irreversible effects.Thus the issue is one of forestalling irreversible changes in livestock farming while pursuing better understanding of critical trajectory changing points.
