Adaptation to Climate Change in Marine Capture Fisheries AgEcon
Grafton, R. Quentin.
This Research Report responds to the challenge for marine capture fisheries of how and when to adapt to climate change. The report presents: (1) a set of fisheries climate change policy options (2) a risk and vulnerability assessment tool and management decision-making framework; and (3) ex ante and ex post climate adaptation possibilities in the marine environment. The report also includes: (1) a discussion of how management objectives and instruments influence resilience and adaptation; (2) a decision-making process to assess vulnerabilities to climate change and to manage adaptation responses; (3) an inter-temporal framework to help decision-makers know when to adapt; (4) a risk and simulation approach to confront the uncertainties of the possible...

Capacity reduction, quota trading and productivity: the case of a fishery AgEcon
Fox, Kevin J.; Grafton, R. Quentin; Kompas, Tom; Che, Tuong Nhu.
We present the first ex post study that quantitatively analyses the effects of a licence buyback and enhanced quota trading on the profitability and productivity of individual vessels in a fishery. Using firm-level data and a profit index decomposition method, we find that small and large vessels and three different trawler fleets all experienced substantial productivity gains in the year immediately following a licence buy-back and the establishment of a quota brokerage service. The apparent ongoing benefits of the buy-back and increased quota trading over the sample period are in stark contrast to the generally unfavourable long-term outcomes commonly associated with vessel buy-backs in input-controlled fisheries.

Cod today and none tomorrow: The Economic Value of a Marine Reserve AgEcon
Grafton, R. Quentin; Kompas, Tom.
The northern cod fishery was once one of the world’s largest capture fisheries. Using data from the fishery, this research calculated the economic value of a marine reserve using a stochastic optimal control model with a jump-diffusion process. The analysis shows that, an optimal-sized marine reserve in this fishery would have prevented the fishery’s collapse and generated a triple payoff. Even if harvesting had been ‘optimal’ the profits from fishing would have been raised. The recovery time would also have decreased for the biomass to return to its former state and smoothed fishers’ harvests and profits. Following a negative shock, the chance of a catastrophic collapse would have been lowered.

Confronting Uncertainty and Missing Values in Species Conservation Investment with Environmental Value Transfer AgEcon
Akter, Sonia; Grafton, R. Quentin.
Decision tools for species conservation, such as benefit cost analysis (BCA) and project prioritization protocol (PPP) use monetary values to measure benefits or to assign priorities across species. Non-use (or passive) values are an important, yet difficult to quantify, category of benefits. When not estimated they may be assigned a zero value by decision makers. This results in the under-provision of conservation dollars to substantial non-use values generating projects and actions. To overcome the problem, we provide a guide to environmental value transfer (EVT) that allows decision makers to derive indirect estimates of non-use values. Environmental value transfer, together with consideration of estimated benefits uncertainty, promise better decision...

Guide to the Ex-Ante Socio-Economic Evaluation of Marine Protected Areas AgEcon
Grafton, R. Quentin; Akter, Sonia; Kompas, Tom.
Marine protected areas (MPA) potentially offer a wide range of use and non-use benefits. These include critical habitat protection, conservation of marine biodiversity, recovery of threatened and endangered marine species, and increased biomass of targeted marine species. To assess whether such benefits exceed the potential costs, we provide the first-ever comprehensive ex-ante, socio-economic guide to MPA evaluation. Our framework shows how to quantify four key values of MPAs: consumptive, non-consumptive, indirect, and non-use values. The framework also shows how to use decision tools to determine the desirability of establishing MPAs. Overall, the guide offers the promise of improved information and better decision making for marine protected areas.

Non-Market Values and Optimal Marine Reserve Switching AgEcon
Yamazaki, Satoshi; Grafton, R. Quentin; Kompas, Tom.
A stochastic bio-economic model is constructed to analyse the effects of marine reserve ‘switching’ between a ‘no take’ area and a harvested area. The model accounts for both market and non-market values of the fishery. Estimated parameters from the red throat emperor fishery from the Great Barrier Reef are used. Simulations show that an optimal switching strategy is, under a range of scenarios, preferred to fixed reserve and no reserve strategies. An important outcome is that the non-market values associated with the size of the fishery substantially affect both the returns from switching and the closure time.

Residential Water Consumption: A Cross Country Analysis AgEcon
Grafton, R. Quentin; Kompas, Tom; To, Hang; Ward, Michael B..
Survey data from over 1,600 households in ten countries were used to analyse the determinants of residential water demand. Results show that in every country the price elasticity is negative and statistically significant. Households that do not have to pay for the water they use (volumetric water charges) consume about a third more water than similar households that do have to pay such charges. Consumers’ attitudes do not have a statistically significant effect on total water use, although they do increase the probability of households using some water saving behaviours. Volumetric water charges also have an impact on the adoption of water saving actions. Full-cost water pricing appears to be a highly effective instrument to manage residential water...

Water Markets and Scarcity: Australia’s Murray Darling Basin and the US Southwest AgEcon
Grafton, R. Quentin; Landry, Clay; Libecap, Gary D.; O’Brien, R.J. (Bob).
Australia’s Murray-Darling Basin and south western United States share: (1) climate variability resulting in the need for large water storage investment; (2) the need for internal and cross-border (state) water management; (3) an historical over-allocation of water to irrigators; and (4) increasing competition between agricultural and urban demand and in situ environmental and recreational uses. The ability of water markets in these two regions to mitigate water scarcity is compared in this report. The evaluation suggests that on-going water market reform, along with processes to account for the public interest, can promote equity, environmental sustainability and economic efficiency.
