Soil is a finite resource. The growing rate of land take and increasing loss of high-quality soil pose a threat for the intactness of ecosystems and our food security. Land sealing and soil degradation are resulting in a shortage of this resource and to harmful changes in soils. It prevents groundwater recharge and has a negative impact on biodiversity in soils. Climate change factors including rising temperatures and different precipitation levels affect soil quality. We must protect soils and safeguard them for future generations.
The German Environment Agency (UBA) reports positive environmental performance 30 years after German reunification. Air, water and soil much cleaner – climate change remains greatest challenge.
Children and adolescents between the ages of 3 and 17 in Germany have too many persistent chemicals from the per- and polyfluoroalkyl substance group, or PFAS, in their blood. These are the findings of an evaluation of the representative German Environmental Survey for Children and Adolescents, GerES V.
5 December is World Soil Day, an initiative by the United Nations to focus attention on the importance of natural resources. Germany has named a Soil of the Year every year since 2005. Intertidal flat soils are Soil of the Year 2020.
Heavy metals, residues of pharmaceutical drugs and plastic: just a few of the many pollutants contained in sewage sludge. Until recently most of the sludges were used as agricultural fertiliser. Nowadays more than half of it is used and combusted for energy purposes. A new UBA brochure has information on disposal practices and on the current status in sludge treatment and recycling.
The Position paper begins by discussing options on how to further develop EU soil protection law. Compared to the status-quo, strengthening the existing soil protection legislation at EU level would preserve transboundary ecosystem services of soils and also help to effectively implement the ‘land degradation neutrality’ objective.
The Federal Ministry for Environment has presented a plan for the gradual phase-out of the use of the broadband herbicide glyphosate. The Use of Pesticides Ordinance will be amended for this purpose. The German Environment Agency as competent body for the authorisation procedure seeks to make the authorisation of products which harm biodiversity contingent upon certain conditions of their use.
The reuse of treated waste water can help to reduce water shortages. Reused water can contain pathogens and harmful substances, however. On 28 May 2018, the EU Commission proposed a regulation, on minimum requirements concerning the reuse of water. It aims to protect health and the environment. The UBA considers there to be a need for improvement.
CAP reform offers chance for more environmentally friendly agriculture on a broad scale
More than half of Germany's surface area is used for agriculture. Agriculture thus is the largest land user in Germany and a significant contributor to environmental stress. On the other hand, agriculture is also affected, for example, by the effects of climate change. In the flyer "Environment and agriculture 2018" UBA presents key facts about agriculture and environment.
Assessing and managing the effects of glyphosate on diversity and abundance of non-target species fully complies with European and national laws. Glyphosate is expected to have a particularly strong impact on non-target organisms by disrupting food webs in agricultural areas.
An area of 66 hectares of new land is consumed every day in Germany, with severe negative effects on the environment. UBA recommends a fixed quota regime for land and a certificate trading system.
Soil organic carbon (SOC) is associated with many critical soil-derived ecosystem services. But what happens if the SOC content is decreasing? A decline in SOC stock may indicate degradation or even loss of land and soil. Therefore, it is currently discussed whether the SOC stock might play an important role in the realisation of the global Sustainable Development Goals.
