A high biological diversity in our immediate vicinity is as important for life satisfaction as our income. These are the findings that scientists from Senckenberg, the German Centre for Integrative Biodiversity Research (iDiv), and the University of Kiel recently published in the journal \u201cEcological Economics.\u201d For the first time, the researchers were able to show that all across Europe, the individual enjoyment of life is correlated to the number of bird species in one\u2019s surroundings. An additional ten percent of bird species in the vicinity therefore increases the life satisfaction of Europeans at least as much as a comparable increase in income. Nature conservation thus constitutes an investment in human well-being, according to the researchers.<\/p>\n\n\n\n
Under the current pandemic conditions, activities out in nature are a popular pastime. The beneficial effects of a diverse nature on people\u2019s mental health have already been documented by studies on a smaller scale. Scientists of the Senckenberg Gesellschaft f\u00fcr Naturforschung, the iDiv, and the University of Kiel now examined for the first time whether a diverse nature also increases human well-being on a Europe- wide scale.<\/p>\n\n\n\n
To this end, the researchers used the data from the \u201c2012 European quality of Life Survey\u201d to study the connection between the species diversity in their surroundings and the life satisfaction in more than 26,000 adults from 26 European countries. Species diversity was measured based on the diversity of avian species, as documented in the European breeding bird atlas.<\/p>\n\n\n\n
\u201cEuropeans are particularly satisfied with their lives if their immediate surroundings host a high species diversity,\u201d explains the study\u2019s lead author, Joel Methorst, a Ph.D. student at the Senckenberg Biodiversity and Climate Research Centre, the iDiv, and the Goethe University in Frankfurt, and he continues, \u201cAccording to our findings, the happiest Europeans are those who can experience numerous different bird species in their daily life, or who live in near-natural surroundings that are home to many species.\u201d<\/p>\n\n\n\n
Birds are well-suited as indicators of biological diversity, since they are among the most visible elements of the animate nature \u2013 particularly in urban areas. Moreover, their song can often be heard even if the bird itself is not visible, and most birds are popular and people like to watch them. But there is also a second aspect that affects life satisfaction: the surroundings. A particularly high number of bird species can be found in areas with a high proportion of near-natural and diverse landscapes that hold numerous greenspaces and bodies of water.<\/p>\n\n\n\n
\u201cWe also examined the socio-economic data of the people that were surveyed, and, much to our surprise, we found that avian diversity is as important for their life satisfaction as is their income,\u201d explains Prof. Dr. Katrin B\u00f6hning-Gaese, director of the Senckenberg Biodiversity and Climate Research Centre, professor at the Goethe University in Frankfurt am Main, and member of the iDiv. This result becomes particularly obvious when both values increase by ten percent. Fourteen additional bird species in the vicinity raise the level of life satisfaction at least as much as an extra 124 Euros per month in the household account, based on an average income of 1,237 Euro per month in Europe.<\/p>\n\n\n\n
According to the study, a diverse nature therefore plays an important role for human well-being across Europe \u2013 even beyond its material services. At the same time, the researchers draw attention to impending health-related problems. \u201cThe Global Assessment 2019 by the World Biodiversity Council IPBES and studies of avian species in agricultural landscapes in Europe clearly show that the biological diversity is currently undergoing a dramatic decline. This poses the risk that human well-being will also suffer from an impoverished nature. Nature conservation therefore not only ensures our material basis of life, but it also constitutes an investment in the well-being of us all,\u201d adds Methorst in conclusion.<\/p>\n\n\n\n
