The Sustainable Development Strategy for the conservation of wild sturgeons in the Lower Danube in the context of climate change and the European Green Pact
part of
Romania's sustainable development in the European context from vision to action (ISBN 978-606-95687-2-9)
Summary
Aquatic ecosystems face habitat changes caused by the amplification of the climate change phenomenon. The adaptive capacity of river ecosystems and associated biota is reduced, reason for which concrete measures are needed. The European Green Deal represents the main signal related to increasingly intense concerns regarding the development of European policies tackling climate and environmental-related challenges. The paper aims to substantiate the application of sustainable solutions for the conservation of sturgeon species in the Lower Danube basin. This is based on the information volume owned by the National Institute for Research and Development in Environment Protection of Bucharest, as a result of the monitoring activity of these species undertaken between 2011 - 2018. Both the distribution maps of the sturgeon species and the numerical evolution of the specimens captured for monitoring between 2011-2018 are presented, along with the distribution of the captures by species.

At the same time, the impact of climate change on sturgeon populations was analysed and quantified, based on the assessment of the main climatic parameters' variability in the area of interest, with the aim of substantiating the conservation measures proposed for the future. Finally, the measures for improving the state of conservation of sturgeon populations are presented, taking as well into account the need to correlate the national and community regulations.
