Waste production and regional growth of marine activities an econometric model. Bramati Maria Caterina Marine pollution bulletin Coastal regions are characterized by intense human activity and climatic pressures, often intensified by competing interests in the use of marine waters. To assess the effect of public spending on the regional economy, an econometric model is here proposed. Not only are the regional investment and the climatic risks included in the model, but also variables related to the anthropogenic pressure, such as population, economic activities and waste production. Feedback effects of economic and demographic expansion on the pollution of coastal areas are also considered. It is found that dangerous waste increases with growing shipping and transportation activities and with growing population density in non-touristic coastal areas. On the other hand, the amount of non-dangerous wastes increases with marine mining, defense and offshore energy production activities. However, lower waste production occurs in areas where aquaculture and touristic industry are more exploited, and accompanied by increasing regional investment in waste disposal. 10.1016/j.marpolbul.2016.08.025

Does marine financial policy affect total factor productivity of marine enterprises? An empirical evidence based on Chinese first guidance on strengthening finance for marine economy. Marine pollution bulletin In order to accelerate the marine economic transformation, and promote the development of marine finance, the Chinese government has promulgated the first "Guidance on Improving and Strengthening Financial Services for the Development of the Marine Economy" in 2018. This paper constructs a quasi-natural experiment and explores the impact of this policy on the total factor productivity (TFP) of marine enterprises using the difference-in-differences method. The results show that the policy has consolidated the micro foundation of marine finance to accurately serve the high-quality development of the marine economy, and is mainly achieved by reducing financing constraints and optimizing resource allocation efficiency. The promotion effect of TFP is more evident in marine enterprises with secondary industry, tertiary industry, and low government subsidies. In addition, the policy can affect the financing structure of marine enterprises, which can reduce the financing cost of enterprises and increase the number of equity financing of enterprises. 10.1016/j.marpolbul.2023.115493

Archaeology meets marine ecology: the antiquity of maritime cultures and human impacts on marine fisheries and ecosystems. Erlandson Jon M,Rick Torben C Annual review of marine science Interdisciplinary study of coastal archaeological sites provides a wealth of information on the ecology and evolution of ancient marine animal populations, the structure of past marine ecosystems, and the history of human impacts on coastal fisheries. In this paper, we review recent methodological developments in the archaeology and historical ecology of coastal regions around the world. Using two case studies, we examine (a) a deep history of anthropogenic effects on the marine ecosystems of California's Channel Islands through the past 12,000 years and (b) geographic variation in the effects of human fishing on Pacific Island peoples who spread through Oceania during the late Holocene. These case studies--the first focused on hunter-gatherers, the second on maritime horticulturalists-provide evidence for shifting baselines and timelines, documenting a much deeper anthropogenic influence on many coastal ecosystems and fisheries than considered by most ecologists, conservation biologists, and fisheries managers. 10.1146/annurev.marine.010908.163749
