Armstrong","doi":"10.1080/13657305.2023.2273483","DOIUrl":"https://doi.org/10.1080/13657305.2023.2273483","url":null,"abstract":"AbstractExtreme climate events challenge the livelihoods of shrimp farmers worldwide. A comprehensive analysis of farmers’ choices of adaptive measures is essential for developing approaches that can lessen the effects of these climate risks. This study presents the determinants that influence the choice of adaptive measures in response to two climate risks, drought, and irregular weather, using a survey of 437 shrimp farmers in the Vietnamese Mekong region and applying a multinomial logit model. Five adaptation choices identified include changing feeding schedules/stocking densities, changing water exchange schedules, water conservation, water treatments, and early harvesting. The results revealed that education, training, extension services, credit access, farm size, pond numbers, and the farmers’ perception of drought and irregular weather are the main factors influencing farmers’ choices of adaptive measures. Intensive and extensive farmers chose different adaptations to climate risks, with the former applying a variety of measures while the latter chose to change water exchange schedules. The conclusions bring policy implications concerning how to cope with climate risks.Keywords: Adaptationclimate risksmultinomial logit modelshrimp aquacultureVietnam AcknowledgmentsThe authors are very grateful to local officials, shrimp technicians, and farmers who participated in the research interviews.

Khan et al. (Citation2018) examined production risk in pangas fish farming, Theodorou et al. (Citation2020) studied the risk level of harmful algal blooms related to mussel site closures, and Moor et al. (Citation2022) discussed the environmental risk of Mexico clam aquaculture.

Saiful Islam","doi":"10.1080/13657305.2023.2268054","DOIUrl":"https://doi.org/10.1080/13657305.2023.2268054","url":null,"abstract":"AbstractThis study examines the impact of integrated aquaculture-agriculture (IAA) value chain participation dynamics on the welfare of indigenous households using a three-wave household panel dataset from Bangladesh. An innovation of this study is that distributional effects of IAA value chain participation dynamics is investigated by examining economic impacts on all actors across the IAA value chains. We applied random-effects, standard fixed-effects, Heckit panel, and control function approaches to control for endogeneity of IAA value chain participation and unobserved heterogeneity. We found that IAA value chain participation is positively associated with household income and diet quality depicted by the consumption frequency of certain foods, especially fish consumption, and the benefits do not continue to accrue after discontinuing participation. The results also reveal that IAA value chain participation has higher impacts on the welfare of households who were involved in production related IAA value chain activities than upstream and downstream IAA value chain activities.Keywords: Integrated aquaculture-agriculture (IAA)welfare impactfixed effects modelcontrol functionindigenous householdsBangladesh AcknowledgementsThis article is part of the author doctoral dissertation, for which he was awarded the Joseph G.

This technique is referred to as co-location and can result in economic and environmental benefits. Using data from a choice experiment and random utility modeling, this research quantifies public preferences for various co-location options within the lease area of a developing wind farm off Virginia’s coastline. Our estimates show that the average Virginia public household is willing-to-pay upwards of $20 per 1,000 acres for co-location activities. By comparing our results to estimated implementation and management costs of each activity, there is a strong indication that the benefits of co-location exceed the costs. The experimental design of this study can be applied to other offshore wind installments around the U.S. and abroad.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135734526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
