Improving management of water resources requires understanding of the natural and human components and drivers that influence the resources, and how these interact. Development of an integrated modelling process can be useful for gaining and sharing understanding of the impact of the interactions. Here we have developed such a modelling process for the Campaspe basin in northern Victoria, Australia. The model has been used to explore the impact of various scenarios on the water resources.

Water and food security are vital for improving livelihoods in disadvantaged rural areas. Understanding the water cycle is central to the design of watershed development works intended to improve water security. Better farming practices can help improve food security. It is also vital for social constraints and equity to be considered. Finally, a participatory learning approach is useful for ensuring that watershed development work is effective in producing long-term improvement in livelihoods.
