Climate Clever Beef : On-farm demonstration of adaptation and mitigation options for climate change in northern Australia

摘要: This project engaged with beef producers in five regions of northern Australia to identify management options that improve the performance and resilience businesses. The work was done context increasing businesses current climate variability as well projected changes climate. also identified potential synergies conflicts between improved business performance, adaptation practices greenhouse gas emissions management. Three (Qld Gulf, Fitzroy Basin Victoria River District) evaluated mitigation via a benchmarking analysis approach three “focal” properties. Five indicators were for each property – profitability, productivity, land condition, change risk emissions. These detailed analyses complemented by demonstration sites region. Two other Mitchell grasslands NT Barkly Tablelands) used on-property showcase promising previous project. The focal provided systematic process assessing ready means estimating impacts changes. For example, over 15 year period, Qld Gulf its pasture condition dramatically stocking around long-term carrying capacity undertaking wet season spelling. This, combined herd improvements, increased profitability reduced 15%, emission efficiency >100%. The region effectively promoted documented benefits key grazing improving both change. on 16,118km² Barkly, paddock has initial recovery at old bores, overgrazing new through best practice rate spelling. Qualitative showed many are consistent existing recommendations aimed productivity sustainability. Furthermore, these appear have largely neutral implications In contrast, reducing more likely create leave enterprises vulnerable Examples negative consequences measures include production associated carbon sequestration trees (i.e. woody vegetation thickening or regrowth retention) operating costs pricing (if not offset credits). The solid base focussed extension targeting drivers profit, intensity strategies.
