Economic benefits that arise from conservation farming practices need to be assessed over several years to account for improvements in soil structure and nutrient levels. A gross margin model was used to assess benefits over the eight-year period 1999-2006 for 12 regions in the central west of...

In this paper, we assess the potential for rehabilitation of comparative analysis under its new guise of benchmarking. After a brief description of comparative analysis, we discuss the deficiencies that surrounded its fall in reputation: neglect of economic principles, limited scope for action,...

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 10,...

This paper presents a participatory approach being used to monitor the changes in economic and social indicators within the Water Sharing Plan areas in NSW. The approach entails close cooperation and input from the stakeholders comprising engagement and scoping; profiling, literature review and...

This paper examines the issue of incentive-compatibility within environmental stewardship schemes where incentive payments to farmers to provide environmental goods and services are based on foregone agricultural income. The particular focus of the paper is on the role of land heterogeneity,...

Irrigation enterprises can be evaluated from a perspective of technical and environmental efficiency. This study determines the technical and environmental efficiency in irrigated cotton enterprises. This is achieved by investigating efficiency at cotton enterprise in the case study area of the...

The paper discusses the level of water trading within the NSW Irrigation Industry along with water prices, reasons, attitudes and knowledge of both permanent and temporary water trading. It is based on the results of a survey of 1,115 irrigators representing over 10% of the total irrigators'...

The net present value (NPV) of downstream economic benefits of changes in water-yield (W) and salt-load (S) of mean annual river flow received by a lower catchment from an upper catchment are described as a 3-dimensional (NPV,W, S) surface, where dNPV/dW 0 and dNPV/d(S/W) 0. Upstream changes...

A lack of information on economic values, especially non-market values, has contributed to wetland degradation in the Mekong River Delta. To fill this information gap, this study uses choice modelling to estimate biodiversity values of Tram Chim National Park in Vietnam. It is found that...
