A positive relationship between average\u0000annual rainfall, and environmental factors (water availability, species diversity, etc.), is often assumed for areas\u0000with an average annual rainfall of 100-300 mm. However, the global climatological models fail to address an\u0000important issue. The above assumption disregards the fact that a climate change in some dry-land areas is not\u0000limited to climatic factors. It is often accompanied by a pronounced variability in surface properties, such as the\u0000deposition of loess in a wet climatic phase, and of sand during a dry climatic phase. Needless to say, the spatial\u0000variability of the new surface properties may have variable effects on water resources and related\u0000environmental variables. In addition, the climatic models, based on average annual rainfall, disregard the rainfall\u0000characteristics at the rain-shower level, which greatly influence the degree to which rainwater will percolate, or\u0000will be transformed into runoff, thereby significantly affecting the spatial redistribution of water resources. In\u0000other words, a climate change in dryland areas would be expected to have differential hydrological effects in a\u0000sandy area, a rocky area, or in a loess covered area. Differential spatial hydrological effects would be also\u0000expected within each of the areas listed above. The present manuscript deals with the complex relationships\u0000between average annual rainfall, and environmental variables in sandy areas, at three research sites, along a\u0000rainfall gradient of 90-450 mm, in the south eastern Mediterranean area, Israel. Data obtained clearly show that\u0000average annual rainfall is not a good indicator of water resources, and ecosystem structure, in each of the sites;\u0000and the controlling factors vary from one site to another.","PeriodicalId":339110,"journal":{"name":"Journal of Earth Science and Climatic Change","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130403385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also important to reduce the adverse effects of climate changes upon the marine and freshwater\u0000environments, fish, and other animals, and the need to manage other human activities taking place in the sea, to\u0000improve the marine environment and protect the wildlife and the fishing activities. Forms of pollution, including\u0000plastics, and also noise and substrate vibration, from industrial and other activities may affect both the abundance\u0000and quality of fish and other marine animals. This paper deals with fisheries management, and environmental\u0000protection, and concludes that fishermen, fisheries scientists, fisheries managers and environmental interests\u0000must work closely together, if fish are to be adequately protected, and fisheries are to be better managed. It\u0000describes current systems of management. It especially draws attention to the importance of moving towards an\u0000ecosystem-based approach to fisheries management. Such an approach aims to manage all those human activities\u0000that have an impact upon the marine environment and its life forms.\u0000\u0000Keywords: Fish; Fisheries; Environments; Ecosystems; Management; Scientists","PeriodicalId":339110,"journal":{"name":"Journal of Earth Science and Climatic Change","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134218391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
