Sustainability of rangeland pastoralism - a case study from the West Australian arid zone using stochastic optimal control theory

Article Abstract:

Grazing management policies whose optimization is dependent on the state of the rangeland resource were identified by using a model of the rangeland production system and a stochastic optimal approach. The policies were identified based on their stocking rate and season of grazing, decision criteria that involved no discounting of future returns or a 6% discount, and their long-term economic and ecological consequences. Policies that involve seasonal grazing or variable stocking rates were found to be not economically viable. On the other hand, pastoralism in severely degraded lands is not ecologically sustainable although it is economically viable.

Explaining landholders' decisions about riparian zone management: The role of behavioral, normative, and control beliefs

Article Abstract:

The theory of planned behavior is used as a framework for studying how beliefs influence decisions about riparian zone management. The results reveal that overall, landholders with strong intentions to manage their riparian zones differed significantly in terms of their beliefs compared to landholders who had weak intentions to manage their riparian zones.

Fire assisted pastoralism vs. sustainable forestry-The implications of missing markets for carbon in determining optimal land use in the wet-dry tropics of Australia

Article Abstract:

Field sampling of woody vegetation is combined with cost-benefit analysis to compare the social optimality of fire-assisted pastoralism with sustainable forestry. Carbon sequestration is estimated to be significantly higher in the absence of fire.
