In this relation is the disposal of the Hungarian National Climate Change Strategy (Nemzeti Éghajlatváltozási Stratégia), which emphasizes the avoidance of any action that may lower the level of water table (Chapter IV. This correlation is stated among others by the report of the European Environmental Agency titled Groundwater quality and quantity in Europe: „Changes in river flow characteristics, such as surface water abstractions, river channelization and dredging of river channels for various purposes, may lead to decreasing groundwater recharge.” And, dredging of the riverbed may decrease the level of water table of the whole area. Still, it is only a temporary solution and is definitely found demanding. In 2018, River Danube showed the lowest ever level of water, which it held for months - virtually completely impossible for navigation.Īn actual policy paper worded that “recently the number of navigable days went under 250 days a year.” But how about the future? The Strategy on Adaption on Climate Change of the ICPDR (International Commission for the Protection of the Danube River) in 2013 (page 14) stated that („The tendency for drier summers strengthens during the course of the century…”ĭredging of the riverbed may give answers for the low level water discharge. One of the great advantages of inland navigation is that there is no need for any construction here, as "water is there already, we only have to sail it.” The facts of recent years seem to contradict this. “Because the water is already there, we only have to sail it.” Many do not even doubt its reality, however data shows the opposite. It is a wildly distributed opinion that navigation is environment friendly, kind of green. The sentence is supposed to be said by Pompeius to his sailors when they had to transport grain from Sicily to Rome in the stormy see. But the original statement was longer, it was “Navigare necesse est, vivere non est necesse” (Navigation is necessary, living is not necessary). “Navigation is necessary” (Navigare necesse est), we quote often the old romans, mostly to support all plans for navigation developments.

I just love to cook and bake on-board and I'm lucky I don’t get seasick below deck as many people unfortunately do, the only problem when cooking on-board is when it is leaning too much to one side and if we are going on the wrong tack. Although I'm sometimes the Captain of the boat and enjoys it I think I am more than willingly to spend a lot of time down in the galley. Our boat is not that big at all but you never know one day perhaps I really need it. The Coastal Skipper Certificate is compulsory for the sailing of boats larger than 12 x 4 meters. I love night navigation and has an in-depth knowledge of both day and night navigation, 'close to shore' as well as offshore. I have the Coastal Skipper Certificate and this Coastal Skipper Certificate is the second level of the official Swedish nautical training courses for recreational boat drivers. About me: I, Tyra the author of this blog live on a rather small island near the town Vaxholm. The archipelago around Stockholm has over 20.000 islands and islets and it is very dear to me and it is among these I have my home harbor. It is about cruising among all the islands of the Baltic sea and the archipelago of Stockholm especially. Navigare Necesse Est! Hop on-board – Welcome to the blog Navigare necesse est, a blog about sailing and food & drink on-board.
