A Farm Level Evaluation of a New Twinning Technology in Beef Cattle AgEcon
Farquharson, Robert J..
This article describes a farm level case study evaluation of a new beef production technology. The evaluation was undertaken as input into a technical research project aimed at developing farm level management strategies to facilitate use of the twinning technology when it becomes commercially available. The evaluation includes budgeting methods and a Linear Programming analysis. A risk analysis was also conducted in which key factors are varied stochastically and the resulting distributions of activity gross margins compared. The analysis shows that twinning could potentially improve the returns to intensive beef production systems, depending importantly on the level and variability of weaning percentage.

Agricultural response analysis in a longer term framework AgEcon
Farquharson, Robert J.; Cacho, Oscar J.; Turpin, J.E..
Issues of long term soil fertility decline and sustainability are becoming more important for cropping industries in Australia. Helping to manage the level of soil fertility in this context is an aim of economic response analysis. This paper reviews the theory and methods used by economists to derive the optimal level of an input to be used in a production process. In particular, response functions generated by a crop simulation model are used as a basis for the analysis. The use of such models is becoming widespread in the research and extension community. A variety of methods are presented, in increasing order of complexity, to account for the real world characteristics of the production environment in this context.

An Assessment of the Economic Impacts of NSW Agriculture Research and Extension - Conservation Farming and Reduced Tillage in Northern NSW AgEcon
Scott, J. Fiona; Farquharson, Robert J..
This assessment of research and extension in conservation farming in northern NSW was done as part of a systematic process of evaluating the economic, social and environmental impacts of major research, extension and education programs. The conservation farming program was a key area of investment by NSW Agriculture and an evaluation process fulfils accountability and resource allocation requirements. This analysis evaluates the investments by the former NSW Agriculture in conservation farming and reduced tillage programs from the late 1970s to 2002. The benefit-cost ratios (BCR) for no till only and no till plus reduced tillage practices up to 2002 were 4.1:1 and 9:1, respectively. The net present values (NPV) of the benefits from these efforts up to 2002...

An economic assessment of Insecticide Resistance Management strategies in the Australian Cotton Industry AgEcon
Hoque, Ziaul; Farquharson, Robert J.; Dillon, Martin; Kauter, Greg.
Cotton production in Australia is a high-value industry with about 90% of fibre produced being exported to Asia, primarily to Indonesia. One aspect of modern cotton production is the heavy usage of insecticide sprays to combat Helicoverpa insects. The high cost of sprays and the public view of the industry regarding its perceived impact on the environment have led to the development of integrated pest management strategies. The measurement of insecticide resistance within insect populations has also prompted the development of insecticide resistance management (IRM) strategies. The aim of the work reported here is to improve the understanding and adoption of IRM strategies by cotton growers. This is pursued by conducting an economic assessment of...

An economic evaluation of the osmoregulation gene technology to the Australian wheat industry AgEcon
Farquharson, Robert J.; Morgan, J.M.; Brennan, John P..
Episodes of rainfall irregularity and soil moisture deficit have focused attention on the widespread limitation of water supply on winter cereal crop production in Australia. This has motivated a number of efforts at breeding for improved drought tolerance. A recent example involves a cellular adaptation which mitigates water loss through solute accumulation (osmoregulation or osmotic adjustment). An assessment of the performance of osmoregulation yield response in the presence of climate change found that wheat cultivars with this gene are unlikely to be adversely affected by hotter and drier conditions across the wheat belt. The results of an economic evaluation of potential future innovations (wheat cultivars) from the osmoregulation gene technology are...

Analysis of Farming Systems Issues in the Northern Cropping Region of NSW AgEcon
Farquharson, Robert J.; Scott, J. Fiona.
A number of farming systems projects are currently being conducted in the north eastern cropping region of Australia. These are jointly funded by the grains industry and state government R&D agencies, and conducted by the latter with some involvement of private industry. The issues which were the genesis of these projects are basically technological (ie productivity-enhancement) to maintain or improve farm income over time, and environmental to redress natural resource degradation associated with the current system. This paper is concerned with the analysis of results from these projects to provide information which helps grain growers in making decisions. In particular, we aim to consider the issues to be analysed and the characteristics of the...

Changes in Management Can Improve Returns from Cambodian Upland Crops AgEcon
Farquharson, Robert J.; Sareth, Chea; Somrangchittra, Chapho; Martin, Robert J.; Haigh, Bruce M; Scott, J. Fiona; Sopheap, Ung.
Farming systems research for wet-season non-rice upland crops in Cambodia is being conducted with the overall aim of poverty reduction and food security for farmers in the Provinces of Battambang and Kampong Cham. Some of these cash crops exhibit low and variable incomes, especially when grown in the early wet season. Cambodian farmers may borrow money to buy crop inputs and often sell their produce to companies and traders from neighbouring countries, hence they are price takers. Some new crop technologies are evaluated which relate to soil and crop fertility management interacting with climatic factors. The DSSAT crop simulation model is used to predict outcomes from alternative management strategies. Bio-economic analyses are conducted to assess the...

Effect of a Carbon Price on Farm Profitability on Rainfed Dairy Farms in South West Victoria: A First-Look AgEcon
Ozkan, Seyda; Farquharson, Robert J.; Hill, Julian; Malcolm, Bill.
In this study, the possible impacts of different prices of carbon on farm profitability in two dairy farm businesses with different feeding systems operated over five years were analysed. The feeding systems were a ryegrass pasture-based system (RM) and a complementary forage-based system (CF). Data were obtained from a five year farmlet trial which was applied to a scaled up representative farm model. As a first look, a carbon charge was imposed on the systems as they currently operate to gauge the order of magnitude of a carbon charge on dairy systems if they were to continue to operate essentially the same system following the impost of a cost of carbon. The main finding of this study was that overall net present value (NPV) of five years of annual...

Environmental economics and valuation: towards a practical investment framework for Catchment Management Authorities in New South Wales AgEcon
Farquharson, Robert J.; Hill, Christine M.; Bennett, Jeffrey W.; Tracey, Jacqueline.
The Catchment Management Authorities in New South Wales have programs that are collectively investing $436 million over four years to achieve catchment-wide natural resource/environmental improvements. In this paper, we consider the question of how to best allocate these resources so as to increase the well-being of the public within catchments and the state. We consider the current approaches used by CMAs and make a case for Benefit-Cost Analysis as an alternative means of assessing ex ante questions of priority setting at the catchment level and for project appraisal. A major issue for BCA is the estimation of potential benefits from project investments, particularly the estimation of values that catchment communities and those living outside the...

ESTIMATING RETURNS FROM PAST INVESTMENTS INTO BEEF CATTLE GENETICS RD&E IN AUSTRALIA AgEcon
Griffith, Garry R.; Farquharson, Robert J.; Barwick, Steve; Banks, Rob; Holmes, Bill.
This study aimed at estimating the costs and benefits of all beef cattle genetic improvement activity, across Australia, over the period 1970 to the present. The total cumulative Present Value (PV) of investments by industry, government and other agencies into selection, crossbreeding and grading up since 1963, and of imported genetics, was estimated to be $340m (in $2001 at a 7% discount rate). Using a suite of genetic evaluation models, farming systems models and an industry-level model, the cumulative PV of industry returns were estimated. Within-breed selection generated $944m; crossbreeding in southern Australia $255m; changing breed composition in southern Australia $62m; and changing breed composition in northern Australia $8.1bn. The benefit/cost...

Issues of scale and scope in bio-physical modelling for natural resource management decision making in New South Wales AgEcon
Hill, Christine M.; Farquharson, Robert J.; Ferrier, Simon; Grieve, Alastair.
Natural resource management decision making by Catchment Management Authorities in NSW is being aided by a project involving bio-physical modelling and the development of an alternative decision-making framework. The objective of the bio-physical modelling process is to generate predictions of environmental or natural resource outcomes rather than project outputs. These outcomes can then be used in an investment framework to help priority setting and project decision making. Questions that arise in bio-physical modelling include those relating to scale and scope. Scale issues include how to address the landscape impacts of particular (or a series of local) on-ground works proposals. Scope issues include assessment of multiple-attribute responses to...

On the Impact Assessment of ACIAR (Australian Centre for International Agricultural Research) Projects AgEcon
Spriggs, John; Farquharson, Robert J.; Martin, Bob.
The current ACIAR (Australian Centre for International Agricultural Research) guidelines for impact assessment of agricultural development projects see impact assessment as being useful for both accountability to stakeholders and as a learning tool to find out what works, what doesn’t work and why. The methodology involves the use of conventional economic evaluation and the estimation of a money metric based on measuring outcomes in terms of economic surplus changes attributable to directed actions and activities. On the question of accountability to stakeholders, this paper suggests that the money metric may not be the best outcomes-based measure of performance against development goals and that other performance indicators ought to be considered. The...

Policy responses to invasive native species: issues of social and private benefits and costs AgEcon
Farquharson, Robert J.; Kelly, Jason A.; Welsh, Pam; Mazur, Kasia; Bennett, Jeffrey W..
Farm and catchment managers in Australia face decisions about controlling invasive native species (or scrub) which may infest agricultural land. The treatment of this land to remove the infestation and re-establish native pastures is likely to be expensive for landholders. Yet there are potential social benefits from such remediation and so a policy question arises of what to do to about facilitating such change. New South Wales state government legislation addresses this issue through regulations, and the Catchment Management Authorities are responsible for administering public funds to achieve associated natural resource improvements. However, the extent of the private costs and social benefits associated with such changes are not known, which precludes...

Profitability and risk evaluation of novel perennial pasture systems for livestock producers in the high rainfall zone: Context, Approach and Preliminary Results AgEcon
Lewis, Claire; Malcolm, Bill; Farquharson, Robert J.; Leury, Brian; Behrendt, Ralph; Clark, Steve.
The decision to invest in pasture improvement raises various questions for the livestock grazier, with the most pertinent being about the potential returns and risks. In the high rainfall zone of south-west Victoria, researchers have trialled novel perennial pasture systems with the aim of substantially increasing on-farm profits whilst simultaneously improving environmental outcomes. Results from the Hamilton EverGraze® proof site have shown potential to greatly improve livestock production. Promotion of the pasture technology is the next step. Key to this process is developing information about profitability and risk regarding the decision to invest in the new pasture. To help meet this need a model of a representative mixed livestock farm system for the...

The economic cost of weeds in dryland cotton production systems of Australia AgEcon
Hoque, Ziaul; Farquharson, Robert J.; Taylor, Ian; Walker, Steve; Osten, Vikki; Jones, Randall E..
Economic losses and costs associated with weeds in dryland cotton production are important, both for growers and for industry bodies when making decisions about research priorities and research and development funding. A survey was conducted to provide information on weed types, control strategies and estimated costs to growers. We used information from the survey to estimate conventional financial losses due to weeds, and as a basis for evaluating aggregate economic (society) impacts. An economic surplus model was used to estimate the aggregate societal impact of weeds for three production regions in north-eastern Australia. The annual economic costs associated with weeds were estimated to be $41 million, and the on-farm financial costs were $25 million....

Understanding rural life - assessing the social dimensions when encouraging land-use changes in rural areas AgEcon
Race, Digby; Farquharson, Robert J.; Birckhead, Jim; Vernon, Don; Bathgate, Andrew D..
Meshed with the bio-physical and economic dimensions of rural land-use is a social dimension. Understanding the social and economic dimension of rural communities is critical if agencies are to develop effective policies and programs to improve natural resource outcomes. In this paper, we draw on research of the Boorowa community, located in the south-west slopes of New South Wales, to help understand how social changes in rural communities are impacting natural resource management in the Boorowa district. This included: • *Identifying the catalysts for changing land-use in the Boorowa catchment, • *Presenting an effective and efficient methodology for assessing the social and economic impacts of changes in land use at the catchment scale, • *Identifying...

Upland crop technologies in Cambodia: economic evaluations and some adoption issues AgEcon
Farquharson, Robert J.; Scott, J. Fiona; Sareth, Chea.
Agricultural research and development (R&D) has being conducted in the upland districts of Cambodia to develop new farming systems and crop management technologies. Levels of farm income in these areas are relatively low due to small farm sizes and low crop productivity. Work is also planned to encourage the process of adoption of these technologies, and here we investigate how this process can be facilitated. A literature review identifies two important technology characteristics, ‘relative advantage’ and ‘trialability’, for successful adoption. Minimum or target rates of return on investment in new technologies are discussed as a means of investigating how much improvement in relative advantage might be enough to encourage successful adoption of the...
