The aim of the project is to improve the understanding of different land use implications on water resource and land productivity. The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums. The main objectives of this project are: to quantify the effect of different agricultural land uses on the catchment water balance; to estimate the trade-off between carbon sequestration and water resources related to tree plantations and pastures; and to develop models at different spatial scales of catchment water balance for land-use management.

该项目的目的是增进对不同土地利用方式对水资源和土地生产力的影响的了解。该项目旨在利用一项配对集水区研究，比较维多利亚州西南部高降雨量地区两个集水区的碳和水平衡。一个集水区主要用于放牧，而另一个则主要种植蓝桉树。该项目的主要目标是：量化不同农业用地对汇水平衡的影响；估算与人工林和牧场相关的碳固存与水资源之间的权衡；建立不同空间尺度的流域水平衡模型，为土地利用管理提供参考。
