De doelen, zoals vastgelegd in de KaderRichtlijn water, zijn nog lang niet binnen bereik. Geldende normen voor onder andere nitraatgehaltes en residuen van gewasbeschermingsmiddelen worden plaatselijk overschreden. De vereniging van waterbedrijven, Vewin, vraagt om meer maatregelen om de kwaliteit van het ruwe water te verbeteren.
A recent study concludes that the birds of Canada and the United States have taken a substantial hit in the last 49 years. Researchers from several institutions in the U.S. and Canada, including the American Bird Conservancy, the Bird Conservancy of the Rockies, the Cornell Laboratory of Ornithology, and Environment and Climate Change Canada, joined forces for the study.
Der Klimawandel und der Einsatz von Pestiziden wirkt sich auf die Käfer in der Lüneburger Heide aus. Das hat eine Langzeitstudie der Leuphana Universität ergeben. Der Wissenschaftler Thorsten Aßmann hat zusammen mit seinem Team 25 Jahre lang Laufkäfer im Naturschutzgebiet beobachtet. Sein Fazit: Es gibt zwar noch viele Käfer in der Heide, aber weniger Arten. Das ist für Aßmann ein eindeutiges Warnsignal. Die Artenvielfalt sei um fast ein Drittel zurückgegangen, so der Ökologie-Professor, der Käferarten auch in Zukunft in Gefahr sieht.
Stoffe aus der Landwirtschaft beeinträchtigen das Grundwasser «verbreitet und nachhaltig». Dies stellt der Bund in einer nationalen Untersuchung fest. Der Bericht hat politische Brisanz.
It's been well known for quite some time that the human population has been booming like never before. Thanks to advances in technology, medicine and science, people are living longer lives and creating bigger families to follow in their footsteps.
While it's always a benefit for people to have an improved length and quality of life, it also puts a strain on natural resources. Specifically, as more people are born, more food has to be produced. This need for food has created an opening for pesticides, which have been used to minimize pests and help crops flourish.
The French government is preparing to fix a 5m or 10m pesticide-free buffer zone around housing areas, after several local mayors defied the government by banning weed killers like glyphosate in their towns. But environmentalists say such distances fall short of the mark. The government will begin discussing legislation to introduce pesticide-free buffer zones on Monday, an Agriculture Ministry spokesperson told AFP.
America’s agricultural landscape is now 48 times more toxic to honeybees, and likely other insects, than it was 25 years ago, almost entirely due to widespread use of so-called neonicotinoid pesticides, according to a new study published today in the journal PLOS One. This enormous rise in toxicity matches the sharp declines in bees, butterflies, and other pollinators as well as birds, says co-author Kendra Klein, senior staff scientist at Friends of the Earth US. “This is the second Silent Spring.
Expenditure for discovery and development of a new crop protection product is now approaching the $ 300 million mark, while at the same time underpinning critical information gaps in environmental safety assessment. Large information gaps also exist for the safety of a vast number of existing chemicals in commerce. The catastrophy in the insect world inflicted by time-reinforced toxicity of neonicotinoids is a case in point. We are on the brink of an ecological Armageddon as a result of pitfalls in pesticide regulation that fail to identify critical aspects of chemical toxicity.
De uitgaven voor de ontdekking en ontwikkeling van een nieuw gewasbeschermingsmiddel naderen nu de grens van 300 miljoen dollar, terwijl tegelijkertijd kritische leemten in de informatie inzake milieu veiligheid duidelijk zijn geworden. Er zijn ook grote hiaten in de informatie voor de veiligheid van een groot aantal bestaande chemicaliën. De catastrofe in de insectenwereld, die wordt aangetast door de extreme toxiciteit van neonicotinoïden, is hiervan een goed voorbeeld.
Damselfly populations are being harmed by insecticides as researchers find the wildlife scourge of neonicotinoids continues to grow. Some chemicals in this group have already been banned by the EU but thiacloprid is still in widespread use. Similar chemicals in the neonicotinoid family have already been tied to severe decline in bee populations and now it appears the damage is more widespread.
