This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient...

O aumento da pressão sobre os recursos hídricos tem levado muitos países a reconsiderarem os mecanismos utilizados na indução do uso eficiente da água. Isso é especialmente verdade para a agricultura irrigada, uma das principais consumidoras de água. Estabelecer o preço correto da água...

Of water withdrawn for agricultural crop irrigation, a portion is consumed and the remainder comes back to the hydrologic system as return flows. Previous models of irrigation water demand have mostly focused on the change in withdrawals in response to price changes, even though knowledge of the...

The Namoi river catchment in northern NSW is an important irrigation region. Water resources in this region are increasingly stressed. Both surface and groundwater supplies are overallocated in many areas of the catchment. Management options to reduce allocations in line with available supply...

A linear programming economic development model can help regional planners influence the most desirable type of growth for rural areas. Optimal resource use, investment, and industry mix for manufacturing, services. government. and agriculture are reviewed for nine regional macroeconomic goals,...

The viability of irrigated systems in Southern Europe is closely linked to efficient institutional settings and water-allocation mechanisms. A significant, although not widely used, mechanism for water allocation is an intra-sectorial water market. The objective of this paper is to evaluate to...
