The search for renewable energy sources is one of today's most pressing challenges, and biofuels have emerged as a viable solution to meet demand and reduce dependence on fossil fuels. Brazil presents the necessary conditions to stand out as a producer and exporter of biofuels worldwide, due to the country's great biodiversity and favorable climate. Among its biomass sources, microalgae stands out for presenting several advantages, such as high productivity and possibility of cultivation anywhere. This work aims to address the advantages and disadvantages of biofuel production from microalgae focused on the genus Botryococcus, known for the formation of liquid hydrocarbons and high lipid content. The species of the genus have great biotechnological potential, but are little studied, especially B. terribilis, which has diverse distribution and is generally found in alkaline reservoirs, not only in Brazil, but in other tropical climate regions.

The crisis caused by COVID-19 has profoundly affected human activities around the globe, and the Galapagos Islands are no exception. The impacts on this archipelago include the impairment of tourism and the loss of linkages with the Ecuadorian mainland, which has greatly impacted the local economy. The collapse of the local economy jeopardized livelihoods and food security, given that many impacts affected the food supply chain. During the crisis, the artisanal fishers of the Galapagos showed a high capacity to adapt to the diminishing demand for fish caused by the drastic drop in tourism. We observed that fishers developed strategies and initiatives by shifting roles, from being mainly tourism-oriented providers to becoming local-household food suppliers. This new role of fishers has triggered an important shift in the perception of fishers and fisheries in Galapagos by the local community. The community shifted from perceiving fisheries as a sector opposed to conservation and in conflict with the tourism sector to perceiving fisheries as the protagonist sector, which was securing fresh, high-quality protein for the human community. This study explores the socio-economic impacts and adaptations of COVID-19 on Galapagos’ artisanal fisheries based on a mixed methods approach, including the analysis of fisheries datasets, interviews, surveys, and participant observation conducted during and after the lockdown. We illustrate the adaptive mechanisms developed by the sector and explore the changes, including societal perceptions regarding small-scale fisheries in the Galapagos. The research proposes strategies to enhance the Galapagos’ economic recovery based on behaviors and traits shown by fishers which are considered potential assets to build-up resilience.
