The paper contributes to the social-ecological systems literature by adapting and using Elinor Ostrom's Social-Ecological System (SES) framework in the context of a coastal ecosystem. We modified the SES framework in the case of the Ciénaga Grande de Santa Marta (CGSM), an estuarine lagoon in the Caribbean coast of Colombia. The ecological importance of CGSM and its species is undeniable. This paper aims to understand why collective action for a sustainable use of CGSM's fishery resources has not taken place. In order to respond to that question, we created new variables within the social, economic, and political settings of the SES framework. The results show that the fishers' fear of the indiscriminate and strong violence that illegal armed groups have inflicted on them since the 1960s and the economic development in the Colombian Caribbean region help explain the lack of collective action.

We investigate the ecological impact caused by fishing grounds and the fishing gear/methods used by fishers in Ciénaga Grande de Santa Marta (CGSM), an estuarine lagoon located on the Caribbean coast of Colombia. To do so, we build individual and composite ecological sustainable indicators based on the opinions of a group of experienced fishers and a group of scientists. Additionally, we use those indicators to examine the influence of socioeconomic and perceptional factors on fishers’ fishing behaviors and how those behaviors may be affecting CGSM fishery resources. Our results suggest that fishers and scientists differ in their opinions about the impact of fishing on CGSM. Additionally, we found that having a higher level of education, sharing household expenses with other family members and spending more hours fishing lead to ecologically-sustainable fishing behavior, while the perception that the government is responsible for CGSM conservation leads to ecologically unsustainable fishing behavior.

This paper analyzes motivations for coffee roasters to source directly from farmers and how roasters decide whether to use the Direct Trade sustainability label. Direct Trade is an uncertified label connoting an approach wherein roasters negotiate coffee price and quality with farmers without intermediaries, with purported farmer income benefits. We examine semi-structured interviews with 11 US roasters and three coffee stakeholders to identify motivations to source directly, provide customers sourcing information, and use or reject the Direct Trade label. We find that roasters directly source coffee primarily for quality reasons and communicate about sourcing because they believe customers would value coffee more if they understood their sustainable sourcing practices. However, the lack of a clear definition for the Direct Trade label, coffee roaster concerns about the label’s utility, and the threat of “free riders” disincentivizes label use. Without a shared label, customers face high costs for information about directly sourced coffee, which may limit the expansion of a sourcing practice that could benefit farmers.
