A Case Control Study of Bovine Viral Diarrhea Virus (BVDV) Persistent Infection (PI) in Betsukai, Hokkaido, Japan OAK
KADOHIRA, Mutsuyo; TAJIMA, Motoshi; 門平, 睦代.
The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not...

A new biosecurity investment decision framework to promote more efficient biosecurity policy AgEcon
Smith, Harley; Webster, Stewart.
Australian governments spend millions of dollars each year on pre border, border and post border biosecurity programs. While the resourcing of some of these programs is determined by existing deeds of agreement, others, particularly in relation to environmental and social pests and diseases, fall outside of existing decision frameworks. This paper presents a new biosecurity investment decision framework based on economic principles that aims to produce more objectively determined decisions. It determines whether a role for government exists in relation to a specific problem through the application of market failure tests and then guides the user to the most efficient cost recovery mechanism. The framework is presently under active consideration for use by...

A Rule of Thumb for Controlling Invasive Weeds: An Application to Hawkweed in Australia AgEcon
Kompas, Tom; Chu, Long.
We use a bang-bang optimal control model to derive a rule of thumb for an optimal management of invasive weeds, in terms of the marginal benefits and costs of various control actions. Instead of determining the size of infestation under an optimal surveillance measure, the rule specifies the types of land where an invasive weed should be first prevented from establishment, and under what conditions control should be initiated. The types of land are modeled via the heterogeneous vulnerability of land to the weed and likely infestation. This easy-to-use rule is applied to determine how hawkweed should be controlled in Australia, across three potential control strategies: containment, eradication and no action. We investigate this rule-of-thumb in both...

Allocating Vote: Biosecurity - Towards an "Economics-Based" Approach for Setting Priorities for the Importation of Risk Goods AgEcon
Ryan, Michael.
The New Zealand government (through its agency the Ministry of Agriculture and Forestry, MAF) seeks to mitigate the potential negative impacts of importation through requiring commodities that may pose a risk to New Zealand's primary production systems, human health, indigenous flora, fauna or biodiversity to have an import health standard. Given, potential import opportunities exist in a wide variety of commodities from many different countries, the demand for import health standards far outweighs MAF's available resources to develop them. Therefore MAF must have a framework that prioritises which import health standards will be developed. This paper briefly presents the framework MAF is currently using to undertake the prioritisation of import health...

Animal Disease and the Industrialization of Agriculture AgEcon
Hennessy, David A.; Wang, Tong.
The industrialization of animal agriculture has fundamentally transformed animal health markets while animal health innovations have promoted this industrialization. The subtlety of these interactions shows how little we know about agricultural industrialization. To illustrate, we consider three stylized features of industrialized animal agriculture. These are the closing off of production activities from external effects, emphasis on control, and use of biosecurity measures. We find that animal disease externalities should lead to higher stocking on any given farm, and also to deficient entry into animal production. Eradicating the disease in a region increases both the stocking rate per farm and the number of farms. We show that antibiotics as a control...

Area-Wide Management of Fruit-Flies: What are the Costs and the Benefits? AgEcon
Florec, Veronique; Sadler, Rohan; White, Benedict.
Increasing volumes and speed of agricultural trade and the opening of new markets for agricultural products create greater challenges to systems established to protect countries from invasive organisms that can be harmful to human and animal health, crops and natural environments. In reaction to the threat of exotic pests and diseases, the World Trade Organization recognises the right of country members to protect themselves from the risks posed by exotic pests and diseases through the application of Sanitary and Phytosanitary (SPS) measures. One possible response from exporting countries facing SPS trade barriers is to obtain pest-free area (PFA) certification. While large benefits can potentially be achieved from greater access to world markets through...

Assessing the marginal dollar value losses to an estuarine ecosystem from an aggressive alien invasive crab AgEcon
Bell, Brian A.; Menzies, Sharon; Yap, Michael; Kerr, Geoffrey N..
This paper reports on a case study to establish dollar values for loss of biodiversity in the New Zealand coastal marine environment. The study uses the European Shore Crab (Carcinas maenas) as the example alien invasive species and the Pauatahanui Inlet, Wellington, New Zealand, as the ecosystem representative of the coastal marine environment. Choice modelling is the stated preference tool used to elicit marginal dollar values for these various attributes of the inlet. Reallocation of existing government expenditure is used as the payment mechanism. Results indicate a wide range of dollar values for the marginal losses to the environment, with no clear trend on a distance-decay relationship. The probability distributions of the dollar values of the...

Australia’s biosecurity: future challenges for animal industries AgEcon
Nunn, Mike J..
Australia’s very good animal health status faces a wide range of biosecurity challenges that will arise during the next decade from changes in disease risk, ecosystems, technology and the policy environment in which animal producers operate. An understanding of these challenges should help enable producers to adopt management strategies to make their enterprises more resilient, as well as help policy-makers make better-informed choices to maintain and improve the health of Australia’s animals and animal industries.

Behavioral Incentives, Equilibrium Endemic Disease, and Health Management Policy for Farmed Animals AgEcon
Hennessy, David A..
We develop a dynamic capital valuation model in which each farm can take an action with farm-varying cost to increase the probability of not contracting a disease. In the presence of infection externalities, circumstances are identified under which multiple equilibria exist and where the one involving the most extensive set of action takers is socially optimal. It is suggested that costly capital markets are one factor in determining the extent of endemic disease in a region. The introduction of frictions, such as dealing with a cumbersome veterinary public health bureaucracy, can enhance social welfare by encouraging precautionary biosecurity actions. Some technical innovations can reduce social welfare. The model is also extended to study a voluntary...

Contracts for Grain Biosecurity and Grain Quality AgEcon
Abougamos, Hoda; White, Benedict; Sadler, Rohan.
The export of grain from Western Australia depends upon a grain supply network that takes grain from farm to port through Cooperative Bulk Handling receival and storage sites. The ability of the network to deliver pest free grain to the port and onto ship depends upon the quality of grain delivered by farmers and the efficacy of phosphine based fumigation in controlling stored grain pests. Phosphine fumigation is critical to the grain supply network because it is the cheapest effective fumigant. In addition, it is also residue free. Unfortunately, over time, common stored-grain pests have evolved to develop resistance to phosphine and there is a risk that phosphine will become less effective and may need to be replaced with more expensive alternative...

Coordinating to Eradicate Animal Disease, and the Role of Insurance Markets AgEcon
Hennessy, David A..
Farmed animal production has traditionally been a dispersed sector. Biosecurity actions relevant to eradicating infectious diseases are generally non-contractible, and might involve inordinately high transactions costs if they were contractible. If an endemic disease is to be eradicated within a region, synchronized actions need to be taken to reduce incidence below a critical mass so that spread can be contained. Using a global game model of coordination under public and private information concerning the critical mass required, this paper characterizes the success probability in an eradication campaign. As is standard in global games, heterogeneity in private signals can support a unique equilibrium. Partly because of strategic interactions, concentrated...

Development of the shrimp industry in the Western Indian Ocean - a holistic approach of vertical integration, from domestication and biosecurity to product certification ArchiMer
Le Groumellec, Marc; Rigolet, Vincent; Panchayuthapani, Duraisamy; Vandeputte, Marc; Rao, Vemulapalli Manavendra.
The shrimp farming industry in the western Indian Ocean started with Aqualma’s project in 1989, and now several companies farm shrimp in the Mozambique Channel. Despite the remoteness of these projects and their high investment and operating costs, they compete in the global marketplace by efficiently producing high value quality products. To address sustainability and biosecurity issues, Aqualma developed domesticated specific pathogenfree (SPF) broodstock of Penaeus monodon from western Indian Ocean stocks, which have been its exclusive source of post-larvae since 2003. Specific molecular diagnostic tools have been developed for each endemic pathogen detected since 1996, and these are used for routine surveillance of Aqualma’s shrimp stocks along with...

Economic Aspects of Agricultural and Food Biosecurity in the United States AgEcon
Hennessy, David A..
Concerns about biosecurity in the food system raise a variety of issues about how the system is presently organized, why it might be vulnerable, what one could reasonably do to better secure it, and the costs of doing so. After presenting some facts about US agriculture and food, this paper considers three economic aspects of the general problem. One is the global problem, or the way biosecurity measures can affect how countries relate to each other and the global consequences that result. Another is how to best manage the immediate aftermath of a realized threat in order to minimize damage. The third is how to seek to prevent realization of the threat. Some policy alternatives are also presented.
