“…More stringent environmental regulations being proposed and ratified and individual States adopting nationally stringent standards are not without precedent in the industry. 49 Also, Regulation C-1 of the BWM Convention explicitly acknowledges that a party of the BWM may propose more stringent amendments individually or together with other Parties, consistent with international law. In the legal and policy analysis toward potential invasion reduction from ballast water introduction, Firestone and Corbett (2005) think a more stringent discharge standard, presumably, could be included as an additional measure according to Section C. 50 Other than the BWM Convention, certain areas may decide to take action to regulate foreign-flag ships to address a particular concern regionally.…”

This work evaluates efficacies of plausible ballast water management strategies and standards by integrating a global species spread risk assessment with a policy cost-effectiveness analysis. Specifically, we consider species spread risks and costs of port-and vessel-based strategies under both current organism concentration standards and stricter standards proposed by California. For each scenario, we estimate species spread risks and patterns using a higher-order analysis of a global ship-borne species spread model and estimate fleet costs for vessel-and barge-based ballast water treatment systems for each standard. We find that stricter standards may reduce species spread risk by a factor of 17 globally and would greatly simplify the complex network of shipborne species spread. The current policy of IMO standards is most cost-effectively achieved through ship-based treatment, and that any additional risk reduction will be most cost-effectively achieved by port-based (or barge-based) technologies, particularly if these are strategically implemented at the top ports within the largest clusters. Bargebased ballast water management would require a shift in governance, and we suggest that this next level of policymaking could be feasible for special areas designated by the IMO, by State or multistate authorities, or by voluntary port applications.

“…Overall, our work suggests that route-specific management may be a feasible and more effective approach to manage ship-based species invasion risks than then current global "one-size-fits-all" management (Molnar et al, 2008;Wang et al, 2020). While the effect of biogeography and the most appropriate shipping risk metric remain uncertain, shipping clearly homogenizes biodiversity in predictable ways.…”

Spread of nonindigenous organisms by shipping is one of the largest threats to coastal ecosystems. Limited monitoring and understanding of this phenomenon currently hinder development of effective prevention policies. Surveying ports in North America, South America, Europe, Southeast Asia, and Australia we explored environmental DNA community profiles evident of ship-born species spread. We found that community similarities between ports increased with the number of ship voyages, particularly if the ports had similar environments, and when indirect stepping-stone connections were considered. We also found 57 known non-indigenous taxa, some in hitherto unreported locations. We demonstrate the usefulness of eDNA-based tools for global biodiversity surveys, and highlight that shipping homogenizes biodiversity in predictable that could inform policy and management.

“…Based on fuzzy granulation and deep learning, this paper evaluates and estimates the exchange rate transaction risk of international trade goods through qualitative or quantitative methods. e international trade goods exchange rate transaction risk evaluation index system is to establish relevant indicators to evaluate the international trade goods exchange rate transaction risk according to the requirements of evaluation contents and evaluation objectives [20][21][22]. Following the principle of risk assessment index system, the risk assessment index of international trade goods exchange rate transaction is embodied in a hierarchical model [23,24].…”

The change of international trade goods exchange rate transaction has an impact on economic operations and economic stability. Therefore, an international trade goods exchange rate transaction based on fuzzy granulation and in-depth learning is proposed. Based on fuzzy information granulation and BP neural network, this paper analyzes the interest rate evaluation theory. For the future expectation of currency exchange rate, portfolio equilibrium determines the proportional relationship of each component in the portfolio and analyzes the impact of asset price and exchange rate change according to this relationship. Then, it points out the risk evaluation index system, calculates the risk degree of exchange rate transaction of international trade goods, and then evaluates the risk of exchange rate transaction of international trade goods. It completes the research on exchange rate transactions of international trade goods based on fuzzy granulation and in-depth learning. The experimental results show that excessive exchange rate fluctuation will bring the same proportion fluctuation to the asset price in the financial market, and the coordination between exchange rates and the coordination of exchange rate and asset price can promote the steady growth of national economy.
