Hundreds of bird populations in India are collapsing, according to a major new report. Researchers using data collected by more than 15,000 birdwatchers examined trends over a 25-year period, and also over the last five years, and in both cases found numbers had declined overall. Over the last quarter of a century there is data available for 261 species – 52 per cent of which were found to be decreasing in number. And over the past five years, data available for 146 species revealed almost 80 per cent of them were declining.
Neonicotinoid insecticides, also known as neonics, are doing more than killing bees and other insects in record numbers, according to a report issued last month by the Natural Resources Defense Council, an international environmental advocacy group. Neonics, the council says, are contaminating New York State’s soil and water and “hollowing out ecosystems from the bottom up.”
The breeding bird population in Germany declined by around 14 million or eight percent over the period between 1992 and 2016, the Federal Agency for Nature Conservation (BfN) said on Wednesday. The "significant decline" in the number of native birds in meadows, pastures and fields has been continuing, according to an evaluation of thousands of data sets by the agency. "In the open agricultural landscapes, the population of breeding pairs has declined by about two million over a quarter of a century," BfN President Beate Jessel said.
Steve Gillam, Starved Rock volunteer Tom Williams and Starved Rock State Park natural resource coordinator Lisa Sons exchanged jokes and friendly chitchat as they trudged over a muddy path along a field edge, wetland and woods at Matthiessen State Park. They were not seeing many birds, despite sunny, breezy conditions and diverse habitat, during their after-lunch hike over their territory in the Starved Rock Audubon Society Christmas bird count. And they said they had not seen many birds in the morning among the oak trees and canyons in the Matthiessen Dells area.
A decline in bird populations is the first indication that something is ecologically amiss, according to an expert from a wildlife organization. "Birds are the first stimulus of degradation in an area. If there is a decrease in the bird populations somewhere, it indicates that something is wrong there," Ahmet Emre Kutukcu, a wildlife expert from World Wildlife Fund (WWF) Turkey, told Anadolu Agency (AA).
Laut Industrieverband Agrar (IVA) hat das Insektensterben viele Gründe. Problematisch sei, dass es in der heutigen Landschaft weniger Ruderalstandorte gebe, weniger extensive Wiesen und Weiden, weniger Blütenpflanzen, weniger Feuchtgebiete, Hecken, Feldränder und Rohböden.
Auch in einer intensiven Landwirtschaft gebe es viele Möglichkeiten, die Artenvielfalt zu erhöhen. Dazu brauche es Nahrungs- und Nisthabitate, erprobte Hilfen, wie Lerchenfenster, oder größere Abstände bei Saatreihen auf Teilflächen im Getreide. Vor allem aber seien die Hilfen zu planen und zu managen.
The renowned author and whistleblower Evaggelos Vallianatos describes British environmentalist and campaigner Dr Rosemary Mason as a “defender of the natural world and public health.” I first came across her work a few years ago. It was in the form of an open letter she had sent to an official about the devastating environmental and human health impacts of glyphosate-based weed killers. What had impressed me was the document she had sent to accompany the letter.
Als er niets verandert, zijn binnen honderd jaar alle insecten uitgestorven. Dat heeft desastreuze gevolgen voor het ecosysteem. Daarvoor waarschuwen wetenschappers, zo schrijft The Guardian.
De afgelopen 25 tot 30 jaar nam het aantal insecten jaarlijks met 2,5 procent af. Als het in dit tempo doorgaat is er binnen een eeuw geen levend insect meer te vinden. Dat blijkt uit een overzichtsstudie die in vakblad Biological Conservation verscheen. Oorzaken zijn volgens de wetenschappers de intensieve landbouw, verstedelijking, pesticiden en klimaatverandering.
