Currently the South African government is advocating the cultivation of high valued crops and more efficient use of available water resources through the adoption o f more efficient irrigation technology and irrigation scheduling. A requirement of the National Water Act (Act 36 of 1998) is the...

Of water withdrawn for agricultural crop irrigation, a portion is consumed and the remainder comes back to the hydrologic system as return flows.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...

Irrigated agriculture often leads to recharge to local and regional groundwater systems greater than what the systems can absorb, resulting in the development of shallow watertables causing salinity and waterlogging. Policy based on emissions trading offers one option for effective management of...

The nature of the seasonal water market is examined using a theoretical model andempirical evidence from the Victorian market. Drivers of the seasonal opportunitycost of water include the underlying nature of investment in the industry made in thecontext of risky entitlement yields; and the...

A water-crop simulation/mathematical programming model of irrigation water demand in northeastern Colorado is formulated to develop an original concept of derived demand for consumptive use of water. Conventional demand functions for water deliveries are also developed, and the effect of...

In many countries growing water scarcity puts pressure on the irrigation sector, as main consumptive user, to improve performance. In this context, the need for research on institutional policy options for improved water allocation and governance is more and more recognized. Exante evaluation of...

Establishment of efficient farm irrigation practices is influenced by the knowledge the irrigator has concerning both the economic and technological aspects of irrigation. The eventual goal of water conservation research is to have water users establish conservation techniques as parts of their...

Furrow diking can prevent irrigation and rainfall runoff, conserve energy use, prevent soil loss, amd allow producers to reclaim land otherwise unusable, depending on soil, climate, and crops grown in a given area. Initial investment to use this technique may be recovered within the first...

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2...

The supply of water for irrigation is subject to climatic and policy uncertainty. The object of the present paper is to show how the linear and non-linear programming models commonly used in modelling problems such as those arising in the Murray–Darling Basin may be adapted to incorporate a...
