In the Canary Islands, forest location in the western islands caters to meteorological, ecological and hydrological factors, as the water availability, orography and the presence of trade winds among them. From a forestry perspective, vegetation of volcanic islands acts as a buffering as it boosts precipitation from fog condensation mainly in western islands with higher altitudes. Besides, it is also remarkable the role of the forest on the planning process of island watersheds, including water-related natural hazards management by its study, flood prediction, hillslope stability estimation, etc. due to the torrential rainfall regime. At last, forest also affects the erosion processes and soil conservation as it promotes infiltration and due to the protection of the canopy and the forest floor against the raindrop impact, one of the main issues of oceanic islands which affect directly and indirectly their hydrological cycle. Different study cases related to the role of forest in volcanic islands are reviewed throughout this work.</p></div>","PeriodicalId":100649,"journal":{"name":"IERI Procedia","volume":"9 ","pages":"Pages 129-134"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ieri.2014.09.052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86794699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estrogenic compounds (Estrone[E1], 17b-Estradiol[E2], Estriol[E3], 17a-Ethinylestradiol[EE2] and Bisphenol A [BPA]) in rivers of southern Jiangsu, China were investigated to realize their distributions and risks. The results showed E1, E2, E3 and BPA ranged from 1.96 to 143.29ng/L in rivers, with the detection rates from 12.5% to 100%. These estrogenic compounds in waters showed higher contents in winter than in spring and autumn. Levels of E1, E2 and E3 were higher in rivers nearby livestock breeding areas, while the concentrations of BPA were higher in the rivers nearby industrial areas. The risk assessment of estrogenic compounds were performed by the calculation of risk quotient (RQ) based on the predicted no effect concentration (PNEC), which was deduced through a species sensitivity distribution (SSD) model. The RQ values of E1, E2, E3 and BPA were 0.02∼1.87, 1.28∼23.22, 0.01∼0.80 and 0.03∼0.44 respectively. These results imply that harmful ecological effects might happen in some rivers.

It is easy to understand why the water cycle is one of the most environmental drivers affected by climate change. Global warming, leaded last century by the climate change, has involved alterations in the temperature, precipitation and evaporation patters. From the point of view of the water resources, these changes include an increase in the freshwater losses from terrestrial sources (glaciers, ice and snow, lakes, soil moisture, swamps, groundwater, marches and rivers) by evaporation and sublimation from fresh water deposits and transpiration from the vegetation, but also change in the rainfall quantity and patterns.
