| More and more environmental economists are finding themselves working within the unchartered territory of participatory governance. Yet many have not appreciated that the shift from progressive, or ‘technocentric’, governance to participatory governance signifies a corresponding departure from the modern worldview underpinning their theory. This paper has two aims. The first is to contribute to an economic explanation of this worldview shift. The intention here is to help overcome the "disciplinary arrogance" and "close-minded adherence to ... ideological convictions" that Sandra Batie, in a presidential address to the American Agricultural Economics Society, identified as "our own worst enemy" when contributing to debates over how to realise sustainable... |

| Integrated Catchment Management (ICM) can be viewed as an institutional instrument designed to ameliorate losses of economic efficiency that have arisen due to incomplete specification of the privileges and restrictions attached to property rights. If applied appropriately ICM can facilitate the emergence of a market in which parties disadvantaged by incomplete specification attempt to bribe those advantaged, with the aim of obtaining the latter's agreement to more complete specification. The instrument provides potential for transactions costs of bargaining to be reduced substantially by reducing the number of parties eligible to participate in, and installing the state as broker and arbiter of, the bargaining process. Participation by sub-catchment... |

| Use of benefit‐cost analysis for economic comparison of agricultural research projects remains confounded, by lack of rigour in specifying the without‐project scenario and how benefits from an innovation endure after its adoption declines. Failure to account for the without‐project scenario favours projects to the extent that more benefits are foregone than costs avoided. Moreover, it is unreasonable to assume generally that aggregate benefits from an innovation continue at the peak level until the end of a 30–40 year planning horizon. A general BCA model for agricultural research projects is presented to enable flexible handling of these issues. |

| Soil salinisation and waterlogging are significant problems in the Irrigation Areas and Districts of southern New South Wales. Various actions can be taken at either a regional or farm level to alleviate these problems. District surface drainage, sub-surface drainage, pumping from deep aquifers and changes to water pricing policies are regional options, while possible on-farm options include laser controlled landforming, pumping groundwater from shallow aquifers, recycling drainage water, changes to crops and rotations and the adoption of improved irrigation systems. The purpose of this study was to analyse the agricultural benefits of a surface drainage scheme proposed for an Irrigation District in the Murrumbidgee Valley. The objective of the analysis... |

| The whole farm financial effects of laser land forming were analysed using a two stage modelling procedure. In the first stage, linear programming models of representative Murrumbidgee Irrigation Area (MIA) rice farms were used to predict the profit-maximising activity mixes with and without successive increments of land forming. In the second stage, the profit-maximising activity mixes with and without an increment became inputs into a spreadsheet model designed to undertake discounted cash flow analysis of investment in the increment. The transition over time of yields to the achievable levels for land formed layouts was accounted for in the spreadsheet model, as were the effects of taxation (including taxation concessions for land forming) and access to... |

| The value of a seasonal forecasting system based on phases of the Southern Oscillation was estimated for a representative dryland wheat grower in the vicinity of Goondiwindi. In particular the effects on this estimate of risk attitude and planting conditions were examined. A recursive stochastic programming approach was used to identify the grower's utility-maximising action set in the event of each of the climate patterns over the period 1894-1991 recurring in the imminent season. The approach was repeated with and without use of the forecasts. The choices examined were, at planting, nitrogen application rate and cultivar and, later in the season, choices of proceeding with or abandoning each wheat activity. The value of the forecasting system was... |

| When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub‐optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. |

| The Land and Water Management Plans (LWMPs) developed for the irrigation districts in the Murray region of NSW are said to be at the forefront of institutional innovation for integrated resource management. Farmers have been strongly involved both in the development of the Plans (for which cost-sharing arrangements with the NSW Government were agreed in 1996) and in deliberations regarding their implementation. Governance of LWMP implementation has been substantially devolved to Murray Irrigation Limited (MIL) which has operated the irrigation schemes since their privatisation in 1994. Since MIL is owned by its irrigator customers, its role as LWMP implementation authority has effectively shifted the rising watertables of the region (which, due to their... |
