Study Regarding to Aggressions on the Ecosystem Danube Delta – Black Sea and Protective Measures

Summary/Abstract: Danube Delta has suffered damages of habitat and species loss caused by factors, including: construction of dams upstream have degraded obviously flooding regime; creation of agricultural and fishing enclosures which decreased the natural and original surfaces; extending artificial navigation channels that negatively affected the hydrological regime and water quality of lakes; increase of nutrients in the water, industrial pollution and accumulate effluents that led to the reduction of plant and bird species; attempt to exploit quartz sand, very pure and fine, the sea levees, although they were protected as nature reserves because of the specific morphology and sub-Mediterranean vegetation covering them; tourism and illegal fishing; mismanagement of resources of reed and fish. The fact is that there was a slight improvement for the marine ecosystem, reported since the early 90s. At present, the area of the Danube Delta - Black Sea is developing sustainable, in terms of medium and economic perspective. In my study I used comparative methods, investigations, direct observations, measurements, calculations and actual data, obtained from surveys and direct observations, from prestigious, specialized and authorized institutions.
