Women's participation in small-scale aquaculture is growing, but women producers remain in a disadvantaged position compared to men. Reducing gender gaps is at the core of many development programs, but little is known regarding the source of these differences. This paper investigates the main drivers of gender gaps in seaweed small-scale aquaculture by focusing on the analysis of differences between male and women, and across a series of psychological traits.

Abstract

We study the development of aquaculture activities in Chile and the impacts of regulatory changes on location decision for aquaculture production centers. Our study considers a descriptive analysis on the spatial and temporal development of aquaculture production centers. Next, using a panel data we estimate a site selection model to explore determinant factors of site choices for aquaculture production. Our results suggest a clear pattern for the spatial-temporal development of Chilean aquaculture.

This study uses a choice experiment to characterize market segments (consumer preferences heterogeneity) based on three attributes of seafood (mussels) that are affected by ocean acidification: shell appearance, meat color, and nutritional composition. Using a sample of 1,257 individuals from two main cities in Chile, we estimate both the Mixed Logit model and the Latent Class model. We use the individual-specific posterior (ISP) parameters’ distribution to categorize consumers’ heterogeneity based on the signs and intensity (i.e., like or dislike dimension) of these ISPs.

The experiences of aquacultural firms regarding past environmental events and their present risk perceptions of environmental and social threats are key factors in understanding their adaptive response. This study aims to understand marine aquaculture firms' adaptive behavior considering firms' heterogeneity and the relationship between past experiences, present perceptions, and willingness to invest in adaptation.

This study investigates the effectiveness of sustainability labels, environmental attitudes, food safety concerns, and knowledge on Vietnamese consumer preferences for sustainably farmed shrimp. Mixed logit and latent class models were applied to estimate utility functions based on 459 samples collected using a choice experiment. The results indicate that Vietnamese consumers prefer sustainably farmed shrimp to conventionally farmed shrimp. Also, both food safety concerns and consumer knowledge vigorously promote sustainably farmed shrimp choices.
