We always hear about the future of our planet! What will it be?
One of the topics that you often hear about is the global level of water on the planet! Do you think that in Europe each of us uses from 3,000 to 5,000 liters of water a day: an impressive amount, surprising, well hidden in our food. The vast part of this waterfall is in fact used for the production of food, from agriculture to breeding to the food industry: an immense consumption of water that takes place far from our eyes. At the same time, limited water resources are increasingly a worrying problem considering also the growth of the world population and climate change – which cause lasting droughts to the north and south of the planet.
Research and studies that highlight the situation and suggest how to reduce water consumption are numerous, and too often unheard.
AN ATLAS FOR ALL. A group of researchers from Aalto University (Finland) has perhaps found a simple way to better communicate the issues related to water: the Water Scarcity Atlas, an interactive website that, better than other initiatives, allows us to understand the extent of the problem posed by the scarcity of water in the various regions of the world and what could be done.Joseph Guillaume, one of the researchers, emphasizes a truth as obvious as ignored: “The choices that the populations of the north of the planet do daily have important repercussions on the other part of the world. Understanding how the impact of everyone’s actions on water scarcity is the first fundamental step to shape the future. We wanted to create an instrument that would allow everyone, and not just scientists, to understand if the choices that are made from day to day are “sustainable”: we believe we have succeeded ».
WHAT TO DO? The atlas shows how the trend of water availability / scarcity in the last hundred years and potential scenarios for the rest of this century. Playing with the various choices available you can explore different scenarios and check how the different diet can significantly affect the water resources of the entire planet.
“Eating less meat and reducing food waste to zero can greatly reduce per capita daily water consumption,” explains the researcher, referring to those 3,000-5,000 liters a day. “If you do not understand this, it is difficult to find a balance between environmental and human needs, especially in regions of the world where there is greater water scarcity. The task of each of us is also to direct farmers and farmers towards more sustainable choices, including through our consumption: the first step can be made by each of us and is perhaps the most important “.
