Pollution to Solution: Can We Get Rid of Plastics in Our Oceans?

The issue of marine plastic pollution has become a pressing, global concern. A few organizations have been created over the past few decades that have tried to address the threat of marine pollution, but none have been solely dedicated to the issue. This has led to a lack of dedication towards the issue at the international scale, and only recently have increased measures been taken to address marine plastic pollution. The 2030 Agenda for Sustainable Development was created by world leaders in 2015, and since then a number of conferences and independent initiatives have taken place across the globe to promote ocean health. Gatherings like the United Nation’s Oceans Conference and statewide bans on plastic bags can provide the groundwork to evolve these agreements and engage governments and communities to work to reduce marine plastic pollution.

What counts as evidence? Local vs. research knowledge in the evidence-based policymaking movement

While evidence-based decision- and policy-making have become quite the buzzwords in recent decades, what constitutes ‘evidence’ in evidence-based is less straightforward. In this paper, Persson and colleagues help unpack the term evidence in the context of sustainability studies, discuss how scientific evidence sits at the top of the evidence hierarchy, and why ignoring local knowledge can be detrimental to sound decision- and policy-making. Additionally, they suggest an alternate model for considering both local and research knowledge to obtain a more holistic understanding of the subject matter at hand, which they argue may ultimately lead to more applicable and suitable decision- and policy-making.

Preserving Culturally-Important Xochimilco Wetlands Requires Policy and Personal Change

Created by the Aztecs in 500 CE for agriculture, Xochimilco is an area of culturally important wetlands in southern Mexico City. Despite its cultural and economic importance, this area is experiencing wetland degradation and loss due to urban development and water quality issues. Even with a high level of local concern about wetland degradation, little effort will be made toward conservation without a change in public policies regarding local infrastructure and development.

Certified coffee farmers are environmentally friendly and compensated for their efforts: Imagination or reality?

Do you go to the grocery store and look for the Fair Trade™ or Rainforest Alliance™ certified coffee? Many consumers prefer to buy certified coffee because they believe there is an economic benefit to the farmer, environmental benefits, or both. However, do these certifications actually improve farmer income and/or protect important environmental services? A recent study conducted in Uganda suggests that farms that are double or triple certified for coffee production suffer trade-offs between economic and environmental benefits.

Building Barriers to Stop Sea Level Rise, What’s at Stake?

Anticipated growth of coastal communities is expected in the ensuing future. As these communities expand so will the issue of coastal protection. Currently 14% of the continental US has armored shorelines to protect infrastructure and people from storm surges and consequent flooding. However, the biological impact of these barriers is under scrutiny. Research conducted by Gehman and colleagues at the University of Georgia investigated how armored coastlines impact both biotic and abiotic features of coastal-upland boundaries along coastal Georgia compared unarmored and forested locations.
