Europe’s crisis of collapsing bird and insect numbers will worsen further over the next decade because the EU is in a “state of denial” over destructive farming practices, environmental groups are warning. European agriculture ministers are pushing for a new common agriculture policy (CAP) from 2021 to 2028 which maintains generous subsidies for big farmers and ineffectual or even “fake” environmental or “greening” measures, they say.
There has been a steep decline in bird populations in Balochistan (one of the four provinces of Pakistan. Its provincial capital and largest city is Quetta), said conservator of forests and wildlife Balochistan Sharifuddin on Wednesday. The official confirmed that there has been a decline in the overall population of sparrows among other birds in Quetta and other parts of Balochistan. The revelation comes just a day after bird lovers marked the World Sparrow Day on Tuesday (March 20). “Even crow, which was a common bird, has decreased in number,” he remarked.
Bird populations across the French countryside have fallen by a third over the last fifteen years, researchers have said. Dozens of species have seen their numbers decline, in some cases by two-thirds, the scientists said in a pair of studies – one national in scope and the other covering a large agricultural region in central France.
"You are what you eat" is the guiding principle behind a new study comparing the diet of birds today with that of birds dead for more than a century. The results show large changes in the diets of aerial insectivores, or birds such as swallows, swifts, martins and whip-poor-wills that consume insects while in mid-flight. Today, the bulk of the birds' diet is made up of small insects at the lower end of the food web, or at a lower "trophic" level, the researchers say.
Neonicotinoid use has increased rapidly in recent years, with a global shift toward insecticide applications as seed coatings rather than aerial spraying. While the use of seed coatings can lessen the amount of overspray and drift, the near universal and prophylactic use of neonicotinoid seed coatings on major agricultural crops has led to widespread detections in the environment (pollen, soil, water, honey).
Over the past 15 years, neonicotinoid seed treatments have been adopted worldwide and are used on a large proportion of U.S. field crops. Although neonicotinoids are used widely, little is known about how large-scale deployment affects pest populations over long periods. Here, we report a positive relationship between the deployment of neonicotinoid seed-dressings on multiple crops and the emergence of insecticide resistance in tobacco thrips (Frankliniella fusca), a polyphagous insect herbivore that is an important pest of seedling cotton but not soybean or maize.
The State of the Nations Butterfly report which is published every five years shows long term and ten year trends – and it’s waving a danger flag. The most recent report published in 2015 indicates that overall a staggering 76 percent of our butterflies declined in abundance and occurrence over the past 40 years.
Four species of butterfly have become extinct over the past 150 years and the rest face an uncertain future. Our moths are doing no better as the total number over the past 40 years has declined overall by 28 percent, even as low as 40 percent in southern areas.
Over five years in the making, The State of South Africa’s Birds 2018 report used national survey and monitoring data to create a picture of the conservation status of the country’s birds and their habitats. Unfortunately, the study outlines several troubling tends. Overall, it found that 132 of the 856 species in the country were threatened or near-threatened in the country, with 13 Critically Endangered – just one step away from being extinct in South Africa.
Denmark is facing a historic pollution case as it has been revealed that every tenth test sample taken from almost 1,700 wells reveals a level of pesticide residue that is considered too high. As a result, a number of wells have been closed due to the concerns. In its report on the issue, the Geological Survey of Denmark and Greenland (GEUS) found unusually high concentrations and a broad geographic occurrence, establishing that the pesticide residue Desphenylchloridazone is prevalent in the groundwater – in open land and in drinking water wells.
