The Sargassum spp. inundations across the Atlantic and Caribbean that began in 2011 have continued unabated, and new uses for the biomass are being continuously explored. Mangroves protect shorelines, store carbon, enhance water quality, and promote biodiversity. Their restoration can be hindered by poor soils associated with urbanized coastlines. Sargassum spp. application in the form of mulch, compost, and plant tonics has yielded positive results in a range of plants. As part of transforming the inundations to benefit communities, Sargassum spp. compost (SC) was assessed in mangrove seedling production for restoration. Pure SC was mixed with soil/sand medium, as different treatments, for the production of Rhizophora mangle seedlings in “wet” and “dry” nurseries. Plants in the “wet” nursery performed poorly, with 90–100% of plants in 50 and 100% SC, respectively, dying after 6 weeks. Seedlings in all SC treatments in the “dry” nursery survived with obvious and statistically significant treatment differences. Height and number of leaves indicated the best growth in the 75% SC treatment, while the control (0% SC) had the poorest growth. Seedling health, greatest in the control, was poorest in 50 and 100% SC. Elemental analysis of SC, seedlings, and soil/sand medium indicated that several elements (Na, K, Ca, As, and Se) found in high concentrations in the SC were low in the plants. Overall, low sequestration of elements by mangrove seedlings and the reported ability of mangrove soils to reduce element mobilization through chelation indicate the potential use of Sargassum spp. in soil amelioration for mangrove restoration without proportional contamination of the ecosystem. We see the potential use of nuisance Sargassum spp. blooms to support mangrove restoration, leading to increased benefits to coastal communities being affected by the inundations.
This chapter presents a fresh perspective on youth apprenticeships by outlining a proposed vocational placement program based on assessing students to discover their career interests before placing them in vocational settings. The expectation is that, by engaging youth in vocational training that is specifically based on what they enjoy, what they do often and what they can potentially excel in, they are being provided with more favorable opportunities to succeed. Though proactive vocational placement (PVP) is in its embryonic stage, and has not been formally implemented, the chapter covers the proposed steps for implementation as well as a few success stories where strengths-based vocational placement has helped young people to thrive in community organizations and schools in the Bahamas.
Deteriorating water quality of Kingston Harbour, due primarily to sewage discharge and its effect on nearby Hellshire Coast, has been an issue since the 1970s. The implementation of a new sewage treatment facility in 2007 to receive the harbour's waste at Soapberry was expected to make a positive difference. Physico-chemical and biological parameters were used to assess water quality to determine the effect of the facility. Eleven stations used in earlier studies (1990 to 1998) were re-sampled to represent Kingston, Hunts Bay and North East Hellshire coastline over a four week sampling regime between May and June 2011. While temperature, salinity, turbidity, dissolved oxygen and pH remained unchanged between the 1990's and 2011, BOD 5 , faecal coliform and nitrate concentrations indicated that the water quality had improved minimally in Kinsgton and Hellshire,and deteriorated significantly in Hunts. Phytoplankton biomass decreased in Kingston
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
