Drinking water shortage in Germany

Scarce drinking water

Drinking water shortages are no longer a far-fetched scenario in the wake of climate change. Read here to find out how serious the situation really is.

In an interview with Redaktionsnetzwerk Deutschland, Armin Schuster, President of the Federal Office of Civil Protection and Disaster Assistance (BBK), warned of drinking water shortages as a result of climate change. Read on to findout how this will come about, how scarce drinking water could be a possible scenario in the future and how serious the situation really is.

As a rule, drinking water of very good quality flows from German taps. It is closely meshed in this country and is the most strictly controlled foodstuff. And it can be taken for granted at any time within your own four walls. However, climate change has already shown in some municipalities in the past that scarce drinking water in our latitudes could no longer be a far-fetched scenario in the future.

Prominent example: Lauenau. The municipality in Lower Saxony with around 4,000 inhabitants ran out of drinking water for a short time in August 2020. On the one hand, because the rainfall was too low. On the other hand, because the residents used more water during the coronavirus pandemic, for example to water their gardens and fill their pools. As a result, the administration called on its citizens to save water. The fire department also distributed service water from tankers at public collection points. In 2020, there were also municipalities in Hesse where suppliers warned of drinking water shortages and even water reservoirs ran empty.

German water consumption in figures

The average person needs between two and three liters of drinking water. This is the amount they should drink to ensure their survival. The average person in Germany actually consumes around 125 liters of water per day. Around 5 liters are used for drinking and preparing food. The lion’s share of over 100 liters is accounted for by personal hygiene and toilet flushing. However, if we also include total consumption from the industrial and agricultural sectors, we arrive at a figure of around 4,000 liters of water per capita per day. In other words, more than 30 times the direct, personal consumption.

While flood disasters have immediately visible and noticeable effects, drought disasters occur gradually over years and are hardly noticed at first. The subjective perception of the weather can also obscure the actual development of the quantities of drinking water available in the groundwater reservoirs. While rain did not seem to be a scarce commodity in many regions in spring 2021, Germany is currently in the fourth year of drought in a row.

In 2018 and 2019, the heat and lack of rain began to drastically reduce the annually usable and renewable quantities of groundwater and surface water, known as the water supply. According to the Federal Environment Agency, Germany’s water supply averaged over 30 years is 188 billion square meters per year. In 2018, however, it was only 119 billion square meters. There was also a rain deficit in the following years. Like the last seven springs, spring 2021 was drier than the long-term average.

If a soil is too dry for a long period of time and thus also dries out in deeper layers, a vicious circle begins. The short and medium-term water absorption capacity of the soil decreases. Rainwater that falls on dry soil runs off faster than it can wet deeper layers of soil.

This is a particular problem for agriculture and can lead to competition with the public water supply for the amount of water available – so far temporarily and locally limited. And not only that. If adequate amounts of rain fail to fall, as has been the case over the past three years, soils can compress more quickly and be eroded by wind. In addition, plants may no longer be able to fully absorb the fertilizers applied. In addition to crop failures, this can also result in the leaching of accumulated nitrogen and phosphorus salts into the underlying groundwater and thus a reduction in the quality of drinking water in a municipality.

The already suffering forest is also put under additional pressure by dry years and falling groundwater levels. Early leaf fall, branch breakage and reduced resistance to fungal infestation and bark beetles are the result.

Panic not indicated

However, there is no need to panic. In all probability, Germany will not become a desert for many years to come. But a rethink is needed. More mindfulness and perhaps a little gratitude for something that is not a matter of course for almost every second person on earth: running water from the tap. Armin Schuster from BBK summed it up for Redaktionsnetzwerk Deutschland as follows: “I don’t want to sound the alarm, it’s still too early for that. But a resource-conserving, sustainable use of water and an increased ability of the population to protect themselves and help themselves in extreme weather conditions is already highly advisable today”.

The State Academy of Fine Arts: ABK Stuttgart traditionally invites visitors to a campus tour at the end of the summer. A long weekend offers visitors an insight behind the scenes. The academy’s studios and exhibition spaces are on display. This year, students of architecture, design, art, art teaching, art studies and restoration will be presenting their current work and projects online on an interactive platform due to coronavirus: rundgang.abk.live

Among them is the contribution by Chiara Schweizer, a student specializing in the conservation and restoration of paintings and painted sculptures. Her video entitled “Restoration in 90 seconds” is currently going viral on the internet. She created a poetry slam and shows how creative conservators can be. In 90 seconds, she explains what is important in restoration. It is important to put your own creativity in the background in the restoration profession. However, free thought is important in order to break new ground and discuss possibilities from all sides. Her message: science never means standing still.

Do we need professional title protection? A debate

The job title “restorer” is still not protected in most federal states and therefore offers plenty of room for interpretation. Anyone can still call themselves a restorer.

Restauro wanted to know how important a protected professional title is and whether restorers, like architects for example, should organize themselves into chambers.Here you can read the answers from those working in the field of conservation and restoration.
Rainer W. Leonhardt
Head of the Berlin/Brandenburg regional group of the Association of Restorers in the Craft Trades e.V.

There is a protected professional title, the Diplomrestaurator/in and the Restaurator/in im Handwerk. Both professions have undergone thorough training.If this is repeatedly disseminated on all channels in future, together with the information that the term restorer is a worthless designation, a lot could be gained. A joint large-scale publicity campaign would be a good idea here.However, a protected professional title of restorer would not protect us from the fact that the cheapest bidder is still often awarded the contract for restoration work, even though the client is aware that the work required cannot be carried out at the price offered. This often leads to undeclared work and undercutting of minimum wages.A further help would be the consistent demand for references, which would then also have to be randomly checked. A phone call to the architect in charge of the project, the responsible monument conservator or even the client would often be helpful. An organization in a chamber, similar to architects, could solve some problems (Chamber of Crafts?), but even for many architects, the HOAI is repeatedly undermined by clients. We do not believe that it is politically feasible at present to establish a chamber for restorers and that it would also entail further financial burdens and even more bureaucracy for the members.

It would be a great benefit for the restoration profession and for the objects! – Because the milieu of unqualified or semi-qualified providers would be pushed back. Because the public, both institutional and private, would at least be provided with a conceptual criterion that would make it easier to distinguish between professionals and – in fact – amateurs. Because monument authorities would achieve a much more efficient steering effect than before (“… is to be carried out by holders of the title Dipl.-Restaurator…”) with the binding conditions on their already modest subsidies, which would benefit the cultural asset. These positive consequences for the private sector and private clients should not be overestimated. In the existing market order, they can continue to award contracts to anyone and everyone. This is essential, whether we consider it harmful or not at this point, because it is free contract law. However, it would of course have an enormous binding effect on the awarding of public contracts controlled by budgetary law. Nevertheless, a massive confusion would remain, which consists of the fact that in addition to us, the academically trained restorers, there are also “restorers in the trade”. The art of explaining the underlying – for us, of course, essential! – The art of briefly and plausibly explaining the underlying differences to a wider public has not yet been invented. Chambers are administratively complex and expensive for the individual. They are structures that evolved in the 19th century. I, too, am unsure how these should be evaluated after weighing up all the advantages and disadvantages for our profession. Regional professional registers, a building block of chambers, based on those of chambered professions are just being created by the VDR.

Arnulf von Ulmann
Former head of the Institute for Art Technology and Conservation at the Germanisches Nationalmuseum in Nuremberg

One should realize that any activity in this matter is wasted energy. In Mecklenburg-Western Pomerania, the law was repealed due to lack of demand! You shouldn’t wish for something you obviously don’t need and can’t get. In professional reality, it is no longer necessary to maintain standards.Activities here would be just as pointless. There will be no more new chambers in today’s EU! Likewise, new professions will no longer be recognized there (see new “master craftsman” regulation). The organizational form is too expensive for restorers. Recognition within the VDR has already failed for cost reasons. The registration activities within the VDR have led to resignations.If a chamber were to contribute to safeguarding standards, we would only have good architects and doctors. The development of a quality management system in accordance with DIN would probably be more successful for issues relating to a chamber of restorers, the fee structure and professional recognition. This should be submitted to the CEN mirror committee of the EU. Restorers are members of this committee.

Roland Vogel
Chairman of the Bavarian regional group of the VDR and freelance restorer

A protected professional title is very important, as it allows the professional group legitimized to work on art and cultural assets to be clearly defined. By maintaining lists of restorers, the activities of an unqualified group of people and thus the irresponsible handling of cultural assets can be prevented, at least in the public sphere of monument conservation. As the political landscape continues to support a general deregulation process, and has done so since the European Union came together, it will not be possible to implement statutory protection of professional or occupational titles at state level in the medium term.The only professional title protection laws for restorers enforced by the VDR to date exist in the federal states of Mecklenburg-Western Pomerania and Saxony-Anhalt. Nevertheless, efforts to introduce such a law in other federal states are continuing. In my opinion, the only alternative at present is to place the preservation of our art and cultural assets on a legal basis exclusively in the hands of a specially trained and responsible professional group. However, the creation of regional chambers could also solve the problems mentioned above; fee regulations, quality assurance, training standards, but also professional sociological issues such as the establishment of a pension fund, etc.
