Abstract

Background: Seaweed cultivation in marine environments offers ecological and economic benefits, but the increasing presence of microplastics poses risks. This review explores cultivation techniques and the impact of microplastic pollution on seaweed growth, nutrient absorption, and health. Methods: Literature was sourced from Google Scholar and academic databases using keywords related to seaweed cultivation and microplastic pollution, focusing on peer-reviewed articles, books, and credible reports from the past decade. Studies were selected based on methodological rigor, relevance, and source credibility. The literature was synthesized to highlight key patterns, trends, and knowledge gaps on the impact of microplastic pollution on seaweed farming. Results:  Seaweed aquaculture provides food, biofuel, pharmaceuticals, and environmental benefits, varying cultivation methods by species, environment, and product. Despite growing demand, microplastic pollution threatens seaweed farming and marine ecosystems. This study explores seaweed’s role in microplastic retention, its potential as a bioindicator, and its broader impact on marine health. Urgent action is needed to address plastic and microplastic emissions and mitigate long-term environmental and health risks. Conclusions: Seaweed aquaculture provides food, biofuel, and ecological benefits. However, microplastic pollution threatens its sustainability. Immediate action is required to address plastic pollution, as it poses long-term risks to marine ecosystems and human health. Governments are increasingly focusing on mitigation measures to address these pressing issues.

Abstract

The strategic development of the Blue Economy (BE) is central to Tanzania’s national and regional aspirations for inclusive growth and poverty reduction, with small and medium-sized enterprises (SMEs) constituting its operational backbone. However, the transformative potential of BE sectors fisheries, aquaculture, coastal tourism, and maritime services is critically constrained by a persistent financing gap. This systematic review synthesizes current evidence to diagnose the binding financial constraints faced by BE-SMEs in Tanzania and to evaluate viable pathways for intervention. Employing a structured methodology, the review critically analyzes peer-reviewed literature, policy documents, and institutional reports from 2006 to 2025. The synthesis identifies a consistent quartet of barriers: stringent collateral requirements underpinned by information asymmetry, elevated lender risk perceptions due to sectoral volatility and climate exposure, pervasive deficiencies in SME financial records and business planning, and cumbersome loan application procedures. Concurrently, the analysis surfaces converging opportunity domains, including the adaptation of group-based and credit-guarantee mechanisms, the deployment of digital and alternative data for risk assessment, and the design of financial products tailored to seasonal cash flows. The review concludes that bridging the finance chasm requires a systemic shift towards blended financial instruments, policy-driven credit infrastructure improvements, and lender innovations in underwriting technology. By aligning financial systems with the distinct realities of BE-SMEs, Tanzania can unlock sustainable, equitable growth within its ocean-based economy.
