This study aims to explore the risk level of pufferfish and lionfish by comparing them among Turkish marines. In addition, this study focuses on comparing pufferfish with lionfish to determine which one is more dangerous for marine economics in Türkiye.

This study employs descriptive content analysis to give some qualitative evidence for the related literature. As a sample case, Türkiye was selected in the context of being a country in the Mediterranean Basin. By reviewing recent news, reports and publications, this study firstly will conclude how invasive alien marine species affect Turkish marines. Then, pufferfish and lionfish will be compared together to determine the risk level of these species for Turkish marine economics.

As a result of descriptive findings, it is seen that captured fishery has been declined in Turkey recently due to many factors including climate change, global warming, overfishing, environmental pollution and attack of invasive alien species. Pufferfish and lionfish are seen as the most spread marine species in Turkish marines. When comparing pufferfish with lionfish, it is seen that pufferfish is more dangerous than lionfish for Turkish marine economics.

This study provides descriptive and original findings as a result of comparison of pufferfish and lionfish due to their impact on Turkish marine economy. It is thought to give useful importation for the fight against invasive alien marine species in the Mediterranean Basin. Future studies can investigate different invasive alien marine species and their impacts on marine economics in the Mediterranean Basin.

Based on the Turkish cases, it is determined that there should be different policies for fight against invasive alien marine species in the Mediterranean Sea. Each marine species has different impacts on seafood market. Some of marine species can be consumed as a seafood product but some of them can't be consumed that policy makers should develop other strategies such as catching them to reduce their population in the local marines.

The spread of invasive alien marine species is still continuing in the Mediterranean Basin. Each country has been affected by the attack of invasive alien marine species. To keep sustainable seafood market and marine economics, countries should both implement common policies and develop policies specific to threats in their own countries.

This study reveals key points in the rise of invasive alien marine species in Turkish marines at first. The main contribution of this study is to be a recent sample for a country which is under attack by invasive alien marine species by giving a comparison of pufferfish and lionfish.

The purpose of the paper is to analyze the different modes of species dispersal and the various types of alien species dispersed in the Indian peninsular region and its impact on the eco system and livelihoods.

The paper portrays the various identified alien species, the scale of invasion thereby resulting in biological disaster caused by mankind.

The paper lists the invasive alien species (IAS) are those that are transmitted from their own ecological niche and to a new niche due to human influence, which causes the biodiversity disaster. International boundaries are indeed porous to the intentional and unintentional movement of species from various eco systems in the country.

It is felt that few initiatives are being taken by International Union for Conservation of Nature (IUCN) and governance of eco system from IAS is a necessity. Sustainable eco system governance (SESG) from invasive alien species should be emphasized to avoid biodiversity disasters that will have an impact on food security and nutrition of human beings.

Ballast water of merchant ship is a source of introduction of invasive species around the globe. The purpose of this paper is to present a quantitative risk assessment applied to a model port, the Port of Arzew in Algeria, and based on an analysis of this port’s shipping traffic.

The risk assessment for introduction of invasive species is interpreted in the form of a probabilistic process, with a combination of two probabilities. The first probability is related to the ability of a species to arrive to the destination (recipient port), depending on the quantity of water ballast discharged and the duration of voyage. The second one is based on the species ability to survive in their new environment, which depends on the environmental similarity between donor port and Arzew port.

This assessment’s outcome consists on a classification of scenarios regarding their acceptability. Consequently, it helped to classify donor ports according to a risk scale, from low risk to high-risk donor ports.

The phenomenon of invasion of aquatic species is a complex process. Factors such as adaptation and tolerance of species, the attendance or absence of predators, were not taken into account in this study.

This study could be used by the maritime administration as a decision-making tool regarding the issue of exemptions under the IMO International Convention on the Management of Ballast Water and Sediments 2004.

This is one of the first known studies in Algeria and dealing with ballast water management. The results of this assessment provide useful information to policy makers, in order to develop a national strategy to reduce the impact of shipping pollution on the marine environment.

This chapter examines the Netherlands’ challenges in safeguarding its low-lying coastline against rising sea levels and the consequences of coastal defense strategies on marine life, particularly in relation to SDG14. Sea-level rise necessitates increased soft coastal defense strategies, affecting seafloor areas and marine biodiversity through sand extraction and sand nourishments. The use of hard structures for coastal defense contributes to the loss of natural coastal habitats, raising biodiversity concerns. The chapter explores the potential benefits of artificial hard surfaces as marine habitats, emphasising the need for careful design to prevent ecological problems caused by invasive species. Strategies for enhancing biodiversity on human-made hard substrate structures, including material variations, hole drilling, and adaptations, are discussed. The ecological impact of marine sand extraction is examined, detailing its effects on benthic fauna, sediment characteristics, primary production, and fish and shrimp populations. Solutions proposed include improved design for mining areas, ecosystem-based rules for extraction sites, and ecologically enriched extraction areas. The ecosystem effects of marine sand nourishments are also analysed, considering the impact on habitat suitability for various species. The chemical effects of anaerobic sediment and recovery challenges are addressed. Mitigation measures, such as strategic nourishment location and timing, adherence to local morphology, and technical solutions, are suggested. The chapter underscores the importance of education in Nature-based Solutions and announces the launch of a new BSc programme in Marine Sciences at Wageningen University & Research, integrating social and ecological knowledge to address challenges in seas, oceans, and coastal regions and support SDG14 goals.

IUCN ‐ The World Conservation Union defines a protected area as an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity, and of natural and associated cultural resources, and managed through legal or other effective means. The Convention on Biological Diversity (1992) describes a protected area as a geographically defined area, which is designated or regulated and managed to achieve specific conservation objective. Protected areas‐national parks, wildlife reserves, wilderness areas, etc. ‐ are the cornerstones of national and international conservation strategies. They act as refuges for species and help maintain critical ecological processes and ecosystem services that intensely managed landscapes and seascapes cannot provide. These places provide space for natural evolution and future ecological restoration. In recent years there has been growing recognition of the benefits that protected areas provide for people: genetic resources for pharmaceuticals and agriculture, traditional medicines; recreational opportunities and ecotourism revenues; sustainable sources of goods such as non‐timber forest products; and refuge for traditional and vulnerable human societies (Dudley et al. 2005). A wide range of management objectives, approaches and types of governance are used within protected areas in different countries. In terms of management objectives, these range from strict protection and exclusion of humans to broad‐scale approaches that include cultural landscapes such as farms and managed forests. IUCN‐The World Conservation Union subdivides protected areas into six categories based on management objectives: Ia: strict nature reserve/wilderness protection area; Ib: wilderness area; II:national park; III:natural monument; IV:habitat/species management area; V:protected landscape/seascape; and VI:managed resource protected area. In terms of governance types, protected areas may be managed directly by a government, co‐managed with other actors such as nongovernmental organizations, or even declared and managed collectively by indigenous peoples and local communities or by the relevant individual or corporate landowner. Today, there are more than 100,000 designated protected areas in the World Database on Protected Areas covering around 11.4 per cent of Earth’s land surface, along with more than 1,300 marine protected areas covering less than 0.5 per cent of the oceans (Dudley et all. 2005).

This paper aims to respond to recent calls by Jones (2014) and Jones and Solomon (Accounting, Auditing & Accountability Journal, 2013) for more studies on biodiversity accounting and reporting. In particular, this paper explores biodiversity reporting of the Murray-Darling Basin Authority (MDBA), an Australian public sector enterprise.

The paper uses content analysis of MDBA’s published annual reports over the period of 15 years (1998-2012). Archival data (from different government departments) are also used to prepare natural inventory model.

The paper finds that although specific species, such as flora and fauna, and habitats-related disclosures have increased over the time, such information still allows only a partial construction of an inventory of natural assets, using Jones’ (1996, 2003) model. However, unlike prior studies that find lack of data availability to be the main impediment for operationalising biodiversity accounting, the abundance of biodiversity data in Australia makes it comparatively easier to produce such a statement.

Informed by the environmental stewardship framework, the results of this paper suggest that the disclosures made by MDBA are constrained potentially due to its use of traditional accounting mechanisms of reporting that only allow tradable items to be reported to stakeholders. An alternative reporting format would be more relevant to stakeholder groups who are more interested in information regarding quality and availability of water, and loss of biodiversity in the basin area rather than the financial performance of the MDBA.

Although there are a growing number of studies exploring biodiversity reporting in Australia, this paper is one of the earlier attempts to operationalise biodiversity (particularly habitats, flora and fauna) within the context of an Australian public sector enterprise.

Will Florida’s agriculture adapt to climate change? Climate disruptions to agriculture and natural resources in Florida are projected to increase in the future. These impacts will be increasingly negative because critical thresholds are being exceeded. This chapter discusses how Florida’s agriculture and natural resources may be affected by climate change in the coming decades.

Agriculture will be affected by invasive alien species, sea-level-rise flooding, and storm surges. A warmer, drier climate will place agriculture in competition with other users for limited water resources. A serious concern for agriculture is that rising sea level will cause coastal groundwater to become more saline and groundwater levels to rise. The loss of coastal wetlands increases the risk of catastrophic damage due to extreme weather events. Degradation of soil and water assets due to increasing extremes in precipitation will challenge both rainfed and irrigated agriculture without the implementation of innovative conservation methods. High night-time temperatures can reduce grain yields and animal-sourced production. Climate change also increases the vulnerability of forests to ecosystem changes due to decreased soil moisture and increased evapotranspiration. The practical implications are that increased innovation will be needed to ensure the adaptation of agriculture and the associated socioeconomic system can keep pace with climate change. Given the difficulties in predicting our future climate, we must develop new risk-transfer innovations that will facilitate damage recovery. Changes in agricultural yields and food prices could have important implications for food security.
