Summary: Globally, illegal fishing is a major factor contributing to declines in fisheries. This study compares different restoration interventions for promoting compliance and finds that all proposed interventions can fully restore fish stocks and bring substantial economic benefits. The model suggests that the Post Keynesian and Institutional model has the highest net returns over 80 years, but all the models have merit in different contexts. The findings of this study are likely applicable to various fishery restoration scenarios.

Summary: Ecological restoration has become a preferred development intervention at the global level, and the United Nations declared the UN decade of restoration in 2021 to recognize its importance. A study on the costs and benefits of restoration in South Africa revealed that, except for a few ecosystems, the benefits of restoration likely exceed the costs by a considerable margin. It is recommended to conduct more research and estimate a wider range of benefits to implement a country-wide restoration program for the benefit of current and future generations.

Summary: Understanding the costs involved in restoration projects is crucial for efficient allocation of funds, setting priorities, minimizing waste, and establishing realistic objectives. Costs for grassland restoration can vary significantly due to the context-dependent nature of ecological restoration.

Summary: The study shows that the mass vaccination campaign against COVID is cost-saving, with significant savings coming from the monetization of the reduction in mortality and cases with sequelae from a social perspective. The intervention is widely cost-effective from the health system perspective as well due to the reduction in the use of resources. From an economic perspective, the vaccination campaign has high social returns.

Summary: Farming systems provide ecosystem and cultural services in addition to food, but the value of these services may conceal large costs often ignored by scholars. A complete assessment of the costs and benefits of farmland is crucial for sustainable and economically efficient land-use planning.

Summary: Restoration is considered an effective strategy for accelerating the recovery of local biological communities, but its effects in marine ecosystems remain unpredictable. The majority of restoration initiatives are concentrated in the northern hemisphere, with studies often experimental and covering small spatial and temporal scales.

Summary: Cost-benefit analysis is crucial for evaluating the welfare gains or losses of investments and should consider environmental impacts. The choice of time horizon can have a significant impact on results, potentially more than discount rates. For projects with long-term environmental effects, timescales of 100+ years are recommended for economic evaluation to avoid bias towards more carbon-intensive or environmentally damaging projects.

Summary: This study evaluated the cost-effectiveness of E-claims and found that electronic processing of claims is more efficient compared with manual processing. The results showed that both providers and purchasers benefited from processing claims electronically. This suggests that scaling up electronic claims can provide economic support and cover more healthcare facilities and NHIS CPCs.

Summary: This scoping review examines the current knowledge and identifies gaps in the knowledge base for cost-benefit analysis and safety evaluation of community paramedicine in rural areas. Three articles were included in the review for cost-benefit analysis, with two of them showing positive cost-effectiveness. However, no articles met the inclusion criteria for safety evaluation.

Summary: Given the need for cost estimating data and tools for dam removal prioritization, planning, and execution in the United States, this study compiled reported costs from 455 unique sources for 668 dams removed from 1965 to 2020. The total cost of these projects was $1.522 billion, with the median cost for dam removals being $157k, $823k, and $6.2M for dams of different heights. Factors such as dam height, annual average discharge, and project complexity were found to be important drivers of removal cost.

Summary: An anonymous survey was conducted to assess the awareness of Irish ophthalmologists regarding the cost of commonly utilized clinical items. The results showed that despite the majority agreeing on the importance of cost in item usage, the average estimation error was 124% and less than 50% of responses were within 50% of the true cost. The study demonstrates variable and limited levels of cost awareness among ophthalmologists, with seniority and self-perceived knowledge not necessarily associated with better estimation accuracy.

Summary: Studies on the economic impacts of invasive alien species often focus on ex-post assessments of control options, but ex-ante assessments are also necessary. This study developed a simulation model to assess the potential impact of the polyphagous shot hole borer on South Africa, taking into account the dynamic mutualistic relations between the beetle and its symbiotic fungus. The model predicted a steady growth in beetle populations and their negative effect on various industries and ecosystems, highlighting the importance of ex-ante economic assessments in invasive species management.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: The Everglades Stormwater Treatment Areas (STAs) are constructed wetlands built to remove phosphorus (P) from agricultural and urban runoff in support of Everglades restoration. Research shows that the levels of calcium (Ca) and alkalinity (Alk) have an impact on phosphorus removal in these wetlands.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
