Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna vegetation would be required, with implications for greenhouse gas emissions, soil health, water resources and dry season environmental flows. This project will track greenhouse emissions and water use from uncleared and cleared savanna that has been converted to pasture and timber plantations, providing critical understanding of the environmental implication of such land use change in savanna.

在过去的十年中，北澳大利亚一直被视为一个潜在的可开发资源，因为南澳大利亚农业地区存在盐渍化，土壤酸化，水资源过度分配和降雨量下降等问题。改良牧场和种植园林是北部地区可能扩大的两种土地用途。需要清除稀树草原植被，这将对温室气体排放、土壤健康、水资源和旱季环境流动产生影响。该项目将跟踪未清理和已清理的稀树草原转化为牧场和木材种植园的温室气体排放和水资源使用情况，为稀树草原这种土地使用变化的环境影响提供重要的理解。
