Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar’s …

Climate change is affecting social and environmental determinants of health through access to safe drinking water, safely managed sanitation systems, and access to health care services and the ability for individuals to break free from unsuitable circumstances. Ecological disturbances such as those caused by climate change can cause a shift in host vectors or a change in habitat that results in a greater likelihood of the pathogen coming in contact with humans. Water, sanitation, and hygiene (WASH) services and their accessibility to populations can directly impact a community’s vulnerability to diseases and limiting factors to increase economic growth. If rural …

Development In Alaska/British Columbia Transboundary Watersheds: A Campaign For International Joint Commission Involvement, Elizabeth Purdy
Capstone Collection
This case study in policy advocacy examines a campaign based in Southeast Alaska known as “Salmon Beyond Borders.” Run by a regional coalition of environmental organizations, indigenous tribes, local municipalities, commercial and sport fishing groups, policy experts, scientists, and concerned citizens, the Salmon Beyond Borders (SBB) campaign seeks a formal referral for International Joint Commission (IJC) involvement from the U.S. Department of State and the Canadian Department of Foreign Affairs. SBB would like the IJC to study the cumulative impacts of mining development in the region’s transboundary watersheds and offer non-binding recommendations from which the U.S. and Canada can negotiate …
