    WW-I-6: Low water

    The bar chart WW-I-6 ‘Low water* shows – for the years of 1961 to 2021 – the number of low-water days in the water-balance related winter half-year (1st October of the previous year to 31st March) and in the water-balance related summer half-year (1st April to 30th September) respectively, prevailing in Germany’s river basins. The structure of the indicator is characterised by individual pronounced low-water events which occurred latterly in the period from 2018 to 2020.

    WW-I-3: Mean discharge

    The bar chart WW-I-3 ’Mean discharge’ shows the mean runoff depth for all river basins in Germany in the hydrological winter half-year (1st November of the previous year till 30th April) and in the hydrological summer half-year (1st May till 31st October) in the years of 1961 to 2021 in millimetres. The runoff depth in the hydrological summer half-year of 2021 decreased significantly during the period of observation, in the amount of slightly more than 100 millimetres.

    WW-R-2: GAK funds for flood protection

    The stacked columns chart WW-R-2 ‘GAK funds for flood protection’ shows the amount of public expenditure on investments made in flood protection measures in million Euros from Federal Government funding, Länder funding, and from additional national funding as well as EU funding during the time series 2007 to 2021. The expenditure has increased significantly since 2013 reaching its highest point in 2018 with just under 400 million Euros. It was possible to reach the same level in 2021.

    WW-R-1: Water use index

    The XY scatter chart WW-R-1 ’Water use index’ shows the development of the water use index between 1991 and 2021. Two time series show the water use index as a percentual proportion of water use compared to the available water supply in the amount of 188 billion cubic metres, which is the mean of available water resources in the years of 1961 to 1990, and as a percentual proportion of water use compared to the available water supply in the amount of 176 billion cubic metres.

    HUE-1: Manageability of climate change impacts

    The illustration ’HUE-1 ’Manageability of Climate Change Impacts’ contains a stacked columns chart which shows the percentual proportion of respondents who were convinced / not convinced that in Germany the problems resulting from climate change would be manageable. For the period from 2002 to 2016, the time series contains data at two-year intervals as well as data for 2021. The categories are as follows: fully convinced, fairly convinced, hardly convinced, not at all convinced.

    BAU-R-2: Green roofs in cities

    The illustration shows a biaxial diagram. For 2020 the green roof area in 15 cities with a population in excess of 500,000 inhabitants per square metre per inhabitant is illustrated by a bar chart. In addition, the percentage of green roof area in respect of the overall roof area examined is illustrated in dot form. In 2020 the green roof area amounted to 0.8 square metres per inhabitant and to approximately 10 per cent of the overall roof area examined.

    BAU-I-1: Heat stress in urban areas – case study

    The illustration BAU-I-1 ’Heat stress in urban areas – case study’ (Wärmebelastung in Städten – Fallstudie) shows three lines representing the number of hot days in the cities of Berlin, Frankfurt am Main and Munich during the period of 1986 until 2021. Apart from Munich, there are a few data gaps in these time series. In addition, a dotted line shows the areal mean for Germany as a whole. All lines show an increase, with fluctuations from year to year.

    BD-I-2: Temperature index for bird species communities

    The illustration BD-I-2 ’Temperature index for bird species communities’ is a line chart with two lines. The first line shows the annual temperature index of frequently occurring breeding bird species for the period 1990 to 2021. The index value shows a significantly rising trend and has increased from 12.14 degrees Celsius in 1990 to 12.40 degrees Celsius in 2021. The second line illustrates the moving 5-year average. Here too the trend is rising significantly.
