Agri-environmental conservation – the case for an environmental levy AgEcon
Crean, Jason.
Recent environmental assessments have highlighted the extent of land degradation in Australia and the significant costs involved in addressing it. With projected investment costs running into tens of billions of dollars, it is not surprising that greater attention is now being focussed on who should pay. One idea gathering significant momentum has been the imposition of an environmental levy. Such a levy would raise public funds to be spent on resource degradation issues and has been proposed to work through the taxation system in a similar fashion to the Medicare levy, albeit for a more limited 10 year period. The paper assesses the arguments behind the imposition of an environmental levy and considers some of the issues associated with its effective...

An Assessment of the Economic, Environmental and Social Impacts of NSW Agriculture's Advisory Programs in Water Use Efficiency AgEcon
Crean, Jason; Shaw, Anna; Singh, Rajinder Pal; Mullen, John D..
An assessment of the economic, environmental and social impacts of extension activities by NSW Agriculture related to water use efficiency is reported. The main vehicle for these extension activities has been a four day vocational course delivered to about 4,400 irrigators under the auspices of the WaterWise on the Farm Initiative (WWF). We focused on four industry/regional complexes - the cotton industry in northern NSW, the lucerne industry in central and northern NSW, the cherry industry and the viticulture industry in southern NSW - where WWF was known to have had an impact. Generally the impact of WWF was to advance the adoption of water use efficient technologies by several years. The investment by NSW Agriculture in year 2002 dollars is likely to be...

ASSESSING THE ON-FARM IMPACTS OF GROUNDWATER REALLOCATION POLICIES IN THE NAMOI VALLEY AgEcon
Carter, A.; Crean, Jason; Young, R.T..
NSW is in the process of implementing major reforms to the management of water resources. One of the key components of these reforms is that “Groundwater management policies should employ the principles of ecologically sustainable development and should be directed at achieving sustainable use of the resource”. The implications of this recommendation vary significantly across NSW according to the level of irrigation development and the environmental conditions of aquifers. The Namoi Valley is one region where groundwater has been identified as suffering from both over allocation and over use. Without change, groundwater dependant ecosystems, irrigators and other users face further declines in groundwater quality and quantity with potential aquifer...

BALANCING TRADE-OFFS IN THE PROVISION OF ENVIRONMENTAL FLOWS IN THE SNOWY RIVER AgEcon
Crean, Jason; Davenport, Scott V..
The NSW, Victorian and Commonwealth Governments are in the process of corporatising the Snowy Mountains Hydro-electric Scheme. As part of this process a water inquiry was established to assist in the determination of the environmental operating conditions of the new business, Snowy Hydro Ltd. The Inquiry’s principal task was to examine the range of environmental issues arising from the current pattern of water flows caused by the Scheme and to develop a comprehensive range of costed options to address these issues. Central to the Inquiry’s deliberations is the re-allocation of water from irrigated agriculture and electricity generation to the Snowy River catchment. This paper focuses on trade-off issues associated with such a re-allocation and the...

Early indicators of the extent of climate change on Australian farms AgEcon
Crean, Jason; Parton, Kevin A.; Hayman, Peter; Mullen, John D..
More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be made of some early indicators. First, the severity of the recent drought was compared with earlier droughts. Second, the trend in rainfall was examined. Third, projections of climate change were reviewed to assess the likely course of climate variability, and hence provide a picture of the severity of future droughts. Although further research is warranted, the indications are that even if rainfall is no lower in future droughts, they may seem more severe because rising temperatures will tend to increase evaporation and reduce runoff.

Economic cost of environmental flows in an unregulated river system AgEcon
Jones, Randall E.; Crean, Jason; Aluwihare, Parakrama B.; Letcher, Rebecca A..
This paper applies a stochastic dynamic programming framework, incorporating links to hydrological and biophysical models, to assess the economic costs of environmental flows in an unregulated river system in the Namoi Valley of northern New South Wales, Australia. Structural adjustment decisions are included in the model to account for farmer responses to changes in environmental flows through the introduction of a water sharing plan. The results of the analysis indicate that the proposed level of environmental flows reduces water extractions by around 6 per cent, and imposes an opportunity cost of less than 1 per cent in terms of reduced net income over a 20-year period.

SOME OBSERVATIONS ON THE NATURE OF GOVERNMENT INTERVENTION IN NATURAL RESOURCE MANAGEMENT AgEcon
Crean, Jason; Pagan, Phil; Curthoys, Catherine.
The objectives of government in relation to natural resource management in agriculture have changed significantly over time. Similarly, the process that government employs to develop natural resource management policy has also evolved. In the past, policy has been developed centrally, while more recently there has been greater effort to involve the community in this process. There are clear linkages between changes in natural resource management objectives and changes in the policy development process. The implementation of the NSW Government’s Water Reforms is used as a case study to consider these linkages and to examine the advantages and disadvantages of moving to a more community based approach to natural resource management. The implications of this...

The implications of policy settings on land use and agricultural technology adoption in North-West India AgEcon
Millham, Nick; Crean, Jason; Singh, Rajinder Pal.
The irrigated rice-wheat cropping system is the predominant and most profitable farming system in north-west India, especially in Punjab. However, there are growing concerns about the environmental effects of the system, particularly with the practice of burning rice stubbles, due to its adverse effects on human health and air pollution. In this paper we consider the wide array of policy settings that tend to favour current land uses and management practices and their impact on the farming system over time. As part of an ACIAR-funded project, we assess the significance of these policies with a view to considering what additional or alternative policies could be put in place to encourage the adoption of approaches or technologies directly concerned with...

Trends in Research, Productivity Growth and Competitiveness in Agriculture in New Zealand and Australia AgEcon
Mullen, John D.; Scobie, Grant M.; Crean, Jason.
Investment in R&D has long been regarded as an important source of productivity growth in New Zealand and Australian agriculture. Perhaps because research lags are long, current investment in R&D is monitored closely. In this paper trends in public investment in R&D and in productivity growth are reviewed. Investment in R&D has been flat in both countries although in recent years investment in New Zealand has increased. Nevertheless research intensity in Australia has been significantly higher than that in New Zealand. Productivity growth is also likely to have been higher. Econometric evidence about the sources of productivity growth is rarely clear. We develop some scenarios about the importance of domestic and foreign R&D and other...
