Efficiently reducing pollution from the seafood industry requires differentiated environmental fees
EfD Authors:
The seafood processing industry plays a vital role in job creation and economic growth, particularly in regions like the Mekong River Delta of Vietnam. However, this industry also generates a significant amount of organic pollutants, predominantly discharged into riverside and seashore areas.
Scuba divers, coral reefs, and knowledge of ocean acidification
EfD Authors:
Ocean acidification (OA) poses a threat to coral reefs by increasing the fragility of susceptible corals to physical damage. As such, the impacts of dive tourism are likely to be exacerbated under acidified conditions. While evidence exists on the impacts of OA, research is scant on scuba divers’ knowledge of OA.
The endogenous formation of common pool resource coalitions
We present the results of framed field (lab-in-field) experiments designed to investigate the endogenous formation of common pool resource (CPR) coalitions when the resource is co-defended with costly monitoring by coalition members and sanctions for encroachment imposed by the government. The experiments were conducted with fishers who were members of Chile's territorial use rights fisheries (TURFs) and in the lab with Chilean university students. Consistent with theoretical predictions, the fishers frequently formed CPR coalitions, even when they could not deter outsider poaching.
Ghost fishing gear and their effect on ecosystem services – Identification and knowledge gaps
EfD Authors:
Abandoned, lost, and discarded fishing gear (ALDFG) is claimed to be a global problem with impacts on marine animals and ecosystems, posing considerable ecological and socioeconomic challenges. Nonetheless, insufficient understanding regarding how marine ecosystem services are affected by ALDFG creates a knowledge gap that challenges a holistic estimation of the long-term economic impacts of using non-degradable fishing gear.
Abundance of Resources and Incentives for Collusion in Fisheries
EfD Authors:
The aim of this study is to explore theoretically the circumstances in which collusion can emerge between artisanal organizations and external agents. We also analyze theoretically how collusion can alter the sustainability equilibria of marine resources. In situations of incomplete information where external agents are not aware of the initial stock of resources, we observe how those agents decide whether to accept or reject offers of collusion from artisanal organizations.
Women engagement, psychological traits, and gender gaps in the small‐scale seaweed aquaculture in Chile
EfD Authors:
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.
