Farm and catchment managers in Australia face decisions about controlling invasive native species (or scrub) which may infest agricultural land. The treatment of this land to remove the infestation and re-establish native pastures is likely to be expensive for landholders. Yet there are...

Woody weeds pose significant threats to the 12.3 billion dollar Australian grazing industry. These weeds reduce stocking rate, increase mustering effort, and impede cattle access to waterways. Two major concerns of woody-weed management are the high cost of weed management with respect to...

This paper reports a research project carried out on behalf of the Ministry of Agriculture and Forestry New Zealand designed to scope the issue of water efficiency in New Zealand and demonstrate where the most significant gains in efficiency can occur. The paper describes the efficiency...

Various methods can be used to construct input-output data for sectoral modelling. These methods are broadly classified in the literature as commodity based survey, non-survey and hybrid approaches. Each approach has its own strengths and weaknesses. This paper presents an alternative approach...

This study explains the results of trade reforms for a scenario where reduced tariffs for all imported commodities under the Uruguay Round (UR) since 1995. The Computable General Equilibrium (CGE) analysis and input-output data for Iran using a base year, 1991, were applied simulating the short...

Integrated catchment policies are widely used to manage natural resources in Australian catchments. Decision support tools available to aid integrated catchment management are often limited in their integration of environmental processes with socio-economic systems. Fully integrated models are...

Choosing a mechanism to encourage landholders to change their land management in order to deliver environmental outcomes is a complicated process. Careful instrument selection may count for little if uptake and adoption are insufficient to meet performance targets. Similarly, investors may...
