This paper presents a literature review on the economic valuation of Harmful Algal Bloom (HAB) impacts, identifying methodological challenges, policy implications, and gaps. Unlike previous literature reviews, we are particularly interested in determining whether the economic valuations of HABs have included a policy analysis.
We conducted a discrete choice experiment to explore whether providing information about a lesser-known issue related to climate change, ocean acidification (OA), affects consumers’ preferences for seafood products in a middle-income country in the southern hemisphere.
We use the Aquaculture Performance Indicators (APIs) methodology to collect data for three aquaculture production systems in Chile, and we also provide a framework to evaluate to what extent the input dimensions explain the outputs using a production function approach. Our analysis considers the production of mussels, algae, and northern scallops. We measured all API categories (outcomes and input metrics) and then grouped the metrics into different dimensions suitable for analysis. We compared the results for each production system and tested the equality of matched pairs of observations.
Aquaculture’s vulnerability to climate change demands urgent, practical adaptation strategies. Strengthening the sector’s resilience requires coordinated efforts across multiple levels, from farms and communities to research systems and governance. Studies have highlighted the need for more climate-resilient practices and clearer guidance on identifying effective technologies and innovations. To address this, FAO developed the Aquaculture Adaptation Framework for Climate Change (Aqua-Adapt). This tool supports the design and implementation of strategies to enhance resilience.

Risk is an inherent characteristic of aquaculture production. For a holistic understanding of risk, the risk assessment process must account for both subjective and objective dimensions of risk. This paper empirically studies the role of risk perception and the risk properties of inputs used in aquaculture to explain the low adoption rates of seaweed farming in Chile. We propose a risk production estimation framework with selectivity to explore the role of risk, given that many aquaculture concessions remain totally or partially unexploited.
The rapid expansion of production in the aquaculture sector could generate various impacts on nearby communities, creating concerns among key stakeholders regarding its consequences in the domains of health, environment, and economic wellbeing. This paper identifies and analyzes stakeholders’ perceptions regarding the impacts of the mussel industry in Los Lagos Region, Chile. Special attention is devoted to identifying convergence and divergence between expert knowledge and stakeholders’ perceptions in the territory in the dimensions of interest.
