In this paper we conduct an analysis of the implementation of HACCP/RMP in the NZ Meat Industry based on the data collected from our recent survey. Nonparametric methods are used to measure the association between plant characteristics such as size, age, activities, and food safety management practices and HACCP/RMP adoption motivations, implementation problems, benefits, and costs. Results give insights into the ongoing process of mandatory RMP in New Zealand.

In contrast with what we perceive is the conventional wisdom about setting emissions taxes under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes will deviate from expected marginal damage if there is uncertainty about the slopes of the marginal abatement costs of regulated firms. Moreover, efficient emissions tax rates will vary across firms if a regulator can use observable firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary.

The opening of a new site for the production of aggregates has both direct and indirect impacts on the environment. The indirect impacts include changes in the environmental costs of hauling aggregates and possible changes in the level of construction activity. In this note, we show that the most likely effect of a new aggregate site is to reduce the truck miles used for aggregate hauling, which is an environmental benefit. We also show that the change in construction activity induced by a new site is likely to be extremely small.

We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

A regulator with a fixed budget to spend on securing environmental benefits from farmed land has to choose between how many acres to enroll and the extent of benefits to require of each enrolled acre. Here we consider, given heterogeneous land, what properties of the environmental benefit-to-cost ratio imply for the choice of optimal program as the available budget varies. Conditions are found such that a program of high benefits on few acres is preferred for any budget level. It is also possible that a program delivering low benefits per acre at low cost is preferred on each land type, and yet a high benefit program is optimal policy, a variant of Simpson’s paradox.

This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates the effects of animal welfare changes on the pig production systems (pig meat) and further on trade flows (trade in pig meat) and environment (water and air pollution). We consider two animal welfare simulation scenarios, namely the status quo – no animal welfare change as regards pig neonatal mortality (baseline scenario) and the case of improving pig neonatal survival (alternative scenario) and compare the impacts on trade and environment between the two...

Ceccato, Lucia; Giannini, Valentina; Giupponi, Carlo.

This work illustrates the preliminary findings of a participatory research process aimed at identifying responses for sustainable water management in a climate change perspective, in two river basins in Europe and Asia. The paper describes the methodology implemented through local workshops, aimed at eliciting and evaluating possible responses to flood risk. Participatory workshops allowed for the identification of four categories of possible responses and a set of nine evaluation criteria, three for each of the three pillars of sustainable development. The main outcome of such activities consists in the ranking of broad response categories instrumental to the objective of the Brahmatwinn research project, i.e. the identification of Integrated Water...

This paper summarizes a pilot project to disseminate site specific weather information that has been processed to estimate field runoff potential of land applied manure. Preliminary feedback indicate the program has value but that additional information is needed to understand how farmers use weather information to make decisions within the regulatory constraints they face.

This paper describes preliminary work on establishing a pilot project for carbon sequestration. The project is intended to simulate the structure of the Permanent Forest Sinks Initiative, a program that may extend to the national level under the supervision of the Ministry of Agriculture and Forestry. In the process of establishing the project, we will identify opportunities and barriers for landowners to engage in the management system of “carbon farming”. We will also use the results of the process to inform policymakers of potential improvements to the Permanent Forest Sinks Initiative and to demonstrate to landowners the benefits of this management system.

Across the country many people engage in recreational boating. In 2008 there were over 12 million registered recreational boats in the United States, and nearly 8% of these were in Florida (US Coast Guard, 2008). Launching boats from publically available ramps is one of the primary methods of marine access. Within Florida, nearly 25% of all boating related trips in 2007 involved launching a trailered boat from a publically available ramp (Florida Fish and Wildlife Conservation [FWC], 2009). With hundreds of thousands of boating trips from dozens of publically accessible ramps, Lee County planners need analytical tools to understand demand and consumer surplus to assist them in evaluating new and enhanced launch facilities. To accomplish this, we...

The goal of watershed scale analysis is to assign to each field unit the best set of agricultural practices in order to achieve a maximum outcome from both environmental and economic perspectives. Watershed physically based models linked to multiobjective optimization models can overcome the high dimensionality of watershed pollution problem. Market based instruments such as permit trading settings which consider abatement measures’ cost heterogeneity have been regarded as being superior to command and control programs. Empirical analysis reveals that when local environmental authority and farmers have different cost information, a permit trading program has the potential to offer cost savings.

Marine species are reproducible resource. Maintaining the stock level of marine species and the sustainability of fisheries development become critical issues in current scientific research areas due to the explosion of human population and exacerbation of natural environment. The traditional method that protects the marine species is the single species approach which set maximum sustainable yield (MSY) to prevent over-harvest. However, with the development of technology and comprehension of marine science, the single species approach has been found obsolete and incapable of dealing with problems of severe depletion of fish stocks and escalation of fisheries confliction. Studies show that when regulations are species specific and species are part of a...

Frisvold, George B.; Bicknell, Kathryn; Bicknell, Ross.

The objective of this research is to undertake an ex ante economic analysis of basic scientific research that aims to identify the gene(s) that control apomictic reproduction, with the ultimate aim of transferring the characteristic into commercially important crops. This paper reports very preliminary results, using the introduction of apomixis into rice as a case study. Apomixis is a natural, asexual method of plant reproduction resulting in offspring that are genetically identical to the mother plant. Apomixis promises to revolutionize plant breeding by providing a system for crop improvement that allows any desired variety, including hybrids, to breed true. This ability will make both breeding and seed production more efficient. It offers the...

A Proposal for the Design of the Successor to the Kyoto Protocol

Karp, Larry S.; Zhao, Jinhua.

The successor to the Kyoto Protocol should impose national ceilings on rich countries’ greenhouse gas emissions and promote voluntary abatement by developing countries. Our proposal gives signatories the option of exercising an escape clause that relaxes their requirement to abate. This feature helps to solve the participation and compliance problems that have weakened the Protocol. We support the use of carefully circumscribed trade restrictions in order to reduce the real or perceived problem of carbon leakage.

The paper presents a concept for a digital platform model for the biomass logistics network for local communities. This concept refers to the strategy for the development of renewable power engineering in Poland to the year 2020, adopted by the Polish government. The status and prospects for biomass production are presented, from which it results that plant production for energy purposes may in the nearest future constitute an important alternative to food production. In turn, main problems connected with the organization of biomass market at the local and regional levels are also discussed. In the proposed model the digital platform would be available on the Internet for all links of the logistics chain, starting from producers and ending with buyers...

A reform to the Kyoto Protocol that allows signatories to pay a fine instead of meeting the target level of abatement would achieve three goals. First, it would defuse one U.S. objection to the agreement: the concern that the cost of achieving the target might turn out to be extremely high. Second, unlike other cost-reducing measures (such as trade in pollution permits) it would increase the equilibrium number of signatories in a non-cooperative participation game. Third, it would make it easier to force signatories to comply with their obligations. We study the participation game under an escape clause using both a Nash Equilibrium and the concept of a stable set when nations are “farsighted”. We compare our results to a prominent model of International...
