Towards a liveable future
Humans have influenced nature since as early as the Ice Age, and over the past century man’s impact has become even greater with our many new technologies and a growing world population. Leiden researchers study this impact and how we can keep it within reasonable limits so that nature can be preserved. Read about it in the new research dossier 'Keeping the planet liveable'.
Man and nature: a complex relationship
Humans were probably already deliberately burning down forest areas at the end of the Ice Age, in order to create a more variable landscape. Since then the world population has grown exponentially, and will continue to do so, which means that man’s impact on the planet will also increase. Natural systems and cycles are becoming disrupted leading to such problems as pollution, depletion of resources and climate change. There is evidence that biodiversity plays a major role in stable ecosystems, and, besides this, nature is a valuable asset for humans because of the peace and relaxation that it can offer. The way we use the planet does not always reflect our desire to create – and maintain - a healthy living environment. In Leiden researchers investigate how we can bridge this gap and how we can provide a good life for ourselves without harming the planet and future generations.

What works for us?
Leiden researchers from different disciplines conduct research on nature and biodiversity, investigating such questions as what man’s impact is in farmland areas, for instance. ‘The Netherlands is a small country with a super-intensive agrarian culture,’ Gert de Snoo explains. De Snoo, Professor of Conservation Biology, and his colleagues discovered that maintaining small areas of nature on farmland, such as wild flowers along the borders of fields, can have a positive effect on biodiversity. Ecotoxicologists conduct research on the effects of biodiversity, exploring the influence of pesticides on local biodiversity. We can also learn from the past. Archaeologists study how man influenced his living environment in the past and what the consequences were. This could be something like the erosion of areas of loess in South Limburg, a process that was started by the Romans, but that only in the 20th century led to extensive mudslides, making the land permanently unsuitable for agriculture. All these insights generate knowledge about how we can best approach our need for food while at the same time preserving the planet.
Don’t exhaust nature: use it wisely
We all want so much today: we want to live in nice houses, fly all over the world and have the newest and best smartphones. All this is possible, but at the same time we are exhausting the planet because all these products and services need raw materials. Over the years Leiden has collected enormous amounts of data on raw material supplies. How do physical flows of raw materials move across the world? Where can they be found? Leiden has the world’s biggest database on this issue, which makes it possible for our researchers to chart the metabolism of society. This offers insights into the best ways of using and reusing sustainable materials so we are better able to create a circular economy.
