Conceptualizing a Sustainable Food System in an Automated World: Toward a “Eudaimonian” Future

The industrialized world has entered a new era of widespread automation, and although this may create long-term gains in economic productivity and wealth accumulation, many professions are expected to disappear during the ensuing shift, leading to potentially significant disruptions in labor markets and associated socioeconomic difficulties. Food production, like many other industrial sectors, has also undergone a century of mechanization, having moved toward increasingly large-scale…

Shift in Fish Assemblage Structure Due to Loss of Seagrass Zostera marina Habitats in Sweden

The areal extent of Zostera marina in the archipelago of the Swedish Skagerrak has decreased by 60% over two decades. To investigate the effects of Z. marina loss on the local fish assemblages, the fish fauna was compared between existing seagrass beds and sites where seagrass had vanished. A field study was carried out at four shallow locations in the outer archipelago of the coast…

Loss of avian phylogenetic diversity in neotropical agricultural systems

Habitat conversion is the primary driver of biodiversity loss, yet little is known about how it is restructuring the tree of life by favoring some lineages over others. We combined a complete avian phylogeny with 12 years of Costa Rican bird surveys (118,127 detections across 487 species) sampled in three land uses: forest reserves, diversified agricultural systems, and intensive monocultures. Diversified agricultural systems supported 600…

The Sixth Extinction Crisis Loss of Animal Populations and Species

Today the number of species is the largest in the history of life; however a considerable proportion of that biodiversity is endangered and many species have suffered anthropogenic extinctions. Species and population extinctions are natural phenomena, and massive biodiversity declines have occurred five times in the remote geological past. However, the current extinction episode, the “sixth extinction wave,” may prove to be the most rapid…

Framing the Problem of Biodiversity Loss & Unanswered Questions

Untangling social-ecological interactions: A methods portfolio approach to tackling contemporary sustainability challenges in fisheries

Meeting the objectives of sustainable fisheries management requires attention to the complex interactions between humans, institutions and ecosystems that give rise to fishery outcomes. Traditional approaches to studying fisheries often do not fully capture, nor focus on these complex interactions between people and ecosystems. Despite advances in the scope and scale of interactions encompassed by more holistic methods, for example ecosystem-based fisheries management approaches, no…

Green Certificate Trading, Renewable Portfolio Standard and Tax Burden Reductions

The article is in Chinese with an English summary: The national-wide issuance and trading of green certificates has been initiated to improve the renewable energy integration and reduce the tax burden in the feed-in tariff scheme. To test the latter effects in green certificate trading, we construct the certificate pricing model to analyze the market equilibrium with or without renewable portfolio standard requirements, and compare…

Automated framing of climate change? The role of social bots in the Twitter climate change discourse during the 2019/2020 Australia bushfires

Extreme weather-related events like wildfires have been increasing in frequency and severity due to climate change. Public online conversations that reflect on these events as climate emergencies can create awareness and build support for climate action but are also used to spread misinformation and climate change denial. To what extent automated social media accounts—“social bots”—amplify different perspectives of such events and influence climate change discourses,…

Life cycle assessment of Indonesian canned crab (Portunus pelagicus)

Indonesia is an archipelagic country with abundant marine wealth that makes it the world’s second largest producer of fish after China. While most of Indonesia’s capture marine fisheries (80%) are consumed domestically, around 90% of blue swimming crab (BSC) products are exported, mainly in cans. This makes up almost half of all BSC products on the global market, with the United States and the European…
