“…Because of its contribution to the employment and economic development of coastal communities, small‐scale aquaculture is an important driver of this industry 2 . In particular, seaweed farming has been highlighted because of its potential to help fulfilling several sustainable development goals (SDGs), such as reducing hunger (SDG 2), improving water quality (SDG 6), mitigating climate change (SGD 13) and protecting the ocean (SDG 14), emphasizing the higher ecological relevance of seaweed farming 3 . It also contributes to generating positive impacts on the community towards achieving decent work and economic growth (SDG 8), industry, innovation and infrastructure (SDG 9), and life on land (SDG 15) 4 .…”

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. We use data from a sample of 152 seaweed producers from central‐southern Chile and perform a matching procedure to generate a balanced sample of male and female producers in the dimensions determining their performance in the sector. Our results show that female producers may exhibit more positive psychological traits such as patience and interpersonal trust. However, women's choices in seaweed farming may be incongruent with these characteristics, as expecting more immediate returns than males, and may not be able to exploit the advantages of collaboration in selling in the sector. This supports the notion that opportunity costs (e.g., other activities in the marine area) and outside options (e.g., fishing versus trade) may be one of the major drivers of gender gaps and suggests that there are barriers keeping women from exploiting their potentially advantageous individual characteristics. Results provide important insights for the design of support instruments aimed at reducing these barriers faced by women in the sector.

Brown algae blooms and invasions have affected 29% of the Earth’s coast, yet there is sparse evidence of the impacts and adaptations of these events. Through a systematic review of empirical literature on these blooms and invasions, we explore the prevalence of conventional analyses of environmental, economic, and social impacts, as well as opportunities for adaptation and valorisation. The study reveals crucial inconsistencies in the current evidence base on algae impacts: fragmented metrics for quantifying blooms and their effects; inconsistent application and testing of prevention measures (e.g. forecasting, early warning systems); reliance on removal as a management approach with limited evidence of associated costs; and scant evidence of the effectiveness of impact mitigation or adaptation strategies. With a focus on economic and societal dimensions of algae events, we introduce emerging opportunities within the blue economy for bloom utilization. The findings highlight the crucial need for harmonized monitoring protocols, robust cost-benefit analysis of management and adaptation options, and evidence of pathways to valorisation of algae biomass.

“…Science-based policies are required to support sustainable global development as the world's population grows. It is crucial to protect the environment, restore it, and assist human society in overcoming the dangers of industrialization and unsustainable exponential expansion 6 . Within this context, many studies have shown that macroalgae are an important marine resource for ecological and sustainable living, aiding in the resolution of today's global issues such as water pollution, ocean acidification, and global warming.…”

This research aims to use eco-friendly Corallina officinalis as an adsorbent for removing harmful malachite green dye streams from industrial effluent, promoting sustainable living and effective microbial growth inhibition. Corallina officinalis biomass was tested for textile dye biosorption, as well as its antibacterial, antioxidant, and cytotoxic properties. The effects of certain parameters, involving pH solution, initial dye concentration, algae dose, and contact time, were investigated on the sorption of dye. Fourier transform infrared spectroscopy and scanning electron microscopy were also used and, the results showed that the functional groups on the surface of algae played an important part in the biosorption process. It was noted that the kinetic data were significantly prominent by the Pseudo-second-order model with regression correlation coefficient $${r}_{2}^{2}$$ r 2 2 values with an average of 0.95232. The biosorption was compatible with both the Freundlich (R2 = 0.9843), and Langmuir (R2 = 0.9653) isotherms, and the maximum removal efficiency for dye reached up to 99.9% in 2 h, 27 °C, stirring speed 120 rpm, pH 6, initial dye concentration 20 mg L−1, and biomass dose 0.03 g L−1. Corallina officinalis had higher antimicrobial activity, with values of minimum inhibitory concentrations ranging from 0.156 to 5 mg mL−1. Corallina officinalis exerted significant radical scavenging activity against tested free radicals. The extract was examined for cytotoxic activity using nine cancer cell lines, which exhibited high cytotoxicity for colon adenocarcinoma with an IC50 value of 25.895 µg mL−1.
