An economic analysis of farm forestry as a means of controlling dryland salinity AgEcon
Cacho, Oscar J.; Greiner, Romy; Fulloon, Lachlan.
Large areas of agricultural land under conventional crops and pastures are at risk of dryland salinisation in Australia. The salinisation problem can be controlled by strategic and large‐scale planting of trees; however, farm forestry enterprises evaluated with conventional discounting techniques do not generally rank as an attractive alternative to annual crops on productive land. In this article, an optimal control model that explicitly accounts for decline or improvement in land quality over a period of 40 years is presented. The optimal area planted to trees and the optimal groundwater‐table trajectory through time are determined under a variety of scenarios. Implications of the results for policy design are discussed.

AN ECONOMIC ANALYSIS OF FARM FORESTRY AS A MEANS OF CONTROLLING SOIL SALINISATION AgEcon
Cacho, Oscar J.; Fulloon, Lachlan; Greiner, Romy.
Dryland salinity emergence is an important land degradation problem in Australia. Large areas of agricultural land where conventional crops and pastures are produced are at risk. The salinisation problem can be controlled by planting trees in conjunction with crops, but a disadvantage of growing trees as a farm enterprise is the long lag between planting and harvest. When farm forestry enterprises are evaluated with conventional discounting techniques they do not generally rank as an attractive alternative to annual crops on productive land. In this paper, a dynamic model that explicitly accounts for decline or improvement in land quality over a period of 40 years is presented. The model is solved for a hypothetical farm on the Liverpool Plains of NSW. The...

Conservation impediments and incentives – progressing the understanding of linkages between the adoption of conservation practices and the motivational orientation of graziers in the tropical savannas AgEcon
Gregg, Daniel; Greiner, Romy.
The adoption of conservation practices is a complex matter – rural landholders consider a wide variety of factors and characteristics when deciding whether to adopt a conservation practice. To confound the issue, recent research has suggested that the goals of landholders affect the adoption of conservation practices by creating a subjective consideration of the relative importance of impediments and effectiveness of incentives in the adoption decision. In this research we describe an empirical link between graziers’ goals and their perceptions of the relative importance of impediments and the effectiveness of incentives in the adoption of conservation practices. The research was carried out in the tropical savannas region of Australia where pastoral...

Estimating community benefits from tourism: The case of Carpentaria Shire AgEcon
Greiner, Romy; Stoeckl, Natalie; Schweigert, Roman.
The small rural communities in Australia's tropical savanna landscapes depend upon the region's natural resources for income and employment. Historically primary industries - including mining, grazing and, in the case of coastal communities, fishing - have been the pillars of economic activity in those regions. More recently, tourism has emerged as an additional nature-based industry, which offers new development and employment opportunities for populations in remote regions. Net benefits from tourism accrue from the balance of economic, social and environmental interactions of tourists with a destination. This paper presents a model of tourism impact in the Carpentaria shire of North West Queensland. A methodology is developed for tracking and quantifying...

Estimating consumer surplus and elasticity of demand of tourist visitation to a region in North Queensland using contingent valuation AgEcon
Greiner, Romy; Rolfe, John.
The Daintree Rainforest is a prime attraction for Tropical North Queensland as a tourist destination. Visitation of the rainforest, specifically the Cape Tribulation section, has increased rapidly as impediments to self-drive access have been removed. This paper examines the potential for the local council to manage the volume of self-drive access to the Cape Tribulation region by price mechanisms. The assessment is based on estimates of willingness to pay from a contingent valuation survey of self-drive tourists to the region, from which estimates of consumer surplus and demand elasticity are derived. A comprehensive discussion of the social and economic implications and transaction costs of price-based mechanisms is offered.

On-farm Costs of Soil Salinisation: a Case Study for the Liverpool Plains in New South Wales AgEcon
Greiner, Romy.
Land affected by a high water table displays waterlogging and salinity effects. This causes costs to farmers through additional land management problems, loss of soil productivity and results in a decline of the farm's capital value. A multi-period mathematical model is developed to investigate best land and financial management strategies for such farms. Water tables rise mainly due to ground water import caused by high recharge in the surrounding parts of the catchment. The hydrological connection between model farm and catchment is established through the variable "condition of the upper aquifer". This paper analyses the effects of different levels of ground water import in terms of progress of soil salinisation, associated farm management responses and...

The Northern Myth revisited: A resource economics research response to renewed interest in the agricultural development of the Kimberley region AgEcon
Greiner, Romy.
The proposal for a 64,000 hectare expansion of the Ord River Irrigation Area is one example of the renewed interest in agricultural development in the tropical north of the Australian continent. Thirty five years ago Bruce Davidson provided conclusive ‘evidence’ that agricultural development in this region was not financially sustainable unless supported by ongoing government subsidies. He argued that this conclusion was unlikely to change in the future. This paper outlines the controversy over past and proposed agricultural developments and explains the role of agriculture in the Kimberley economy today and in relation to other natural resource based industries. In a time when the paradigm of sustainable development recognises ‘quality of life’ and...

The role of grazier motivations and risk attitudes in the adoption of grazing best management practices AgEcon
Greiner, Romy; Miller, Owen; Patterson, Louisa.
The onus on landholders in relation to environmental performance is ever increasing. One tool for achieving environmental improvements is the design and promotion of region-specific ‘best management practices’ (BMPs). These are conservation practices aimed at reducing diffuse source pollution from agricultural lands and thus improving end-of-catchment water quality. A suite of grazing BMPs were developed for the Burdekin Dry Tropics region in a consultative fashion but without explicit consideration of knowledge of adoption processes. It is known from the literature that farmers’ goals and risk perceptions in particular influence adoption decisions. This paper utilises the data from an earlier grazier survey to explore to what extent grazier motivations...
