"AT THE TROUGH." A VIDEO THAT NEEDS TO BE SEEN AGAIN.

Many well-informed, dedicated and concerned individuals produced this video in 2008. Sadly, their warnings about the dirty and dangerous consequences of unregulated factory "farming" in Manitoba have not been heeded. The industry has been given free-rein and continues to expand with few, if any checks and balances. The video is less than an hour long. I implore you to take the time to watch! If you did see it before, perhaps it will remind you again of just how grave these issues really are. If you have not, I know it will concern you, too - perhaps even inspire you to take action of your own. Thank you!

The migratory routes used by the peregrine falcon have been shaped by environmental changes since the last Ice Age, reports a study published in Nature. The paper also presents evidence that the distance travelled during migration is influenced by a genetic factor.

Millions of migratory birds have seasonally favourable breeding grounds in the Arctic, but spend their winters in different locations across Eurasia. However, little is known about the formation, maintenance and future of their migration routes or the genetic determinants of migratory distance.

Xiangjiang Zhan and colleagues combined satellite-tracking data from 56 peregrine falcons from Eurasian Arctic populations with genome data from 35 peregrines to study the migrations of this species. The authors found that five migratory routes were used across Eurasia, which have been shaped by environmental changes since the Last Glacial Maximum (around 20,000–30,000 years ago). Peregrines that migrated longer distances were also found to have a dominant genotype of the gene ADCY8 that — the authors suggest — may be associated with the development of long-term memory.

The authors propose that, in a changing global climate, peregrines in western Eurasia may suffer the highest probability of population declines, move to new wintering areas or perhaps stop migrating altogether. They conclude that using ecological interactions and evolutionary processes to study climate-driven changes in migration could help to facilitate the conservation of migratory birds.

Long-distance movement of microplastics

Microplastics, detected in southern France, could have been transported over 4,500 km from their source, including over continents and oceans, suggests a study published in Nature Communications. The findings suggest that microplastic pollution can spread globally from its sources to remote regions.

Plastic pollution has been documented at high elevations and latitudes, and in regions with little local plastic use. The transportation of microplastics through the atmosphere has been suggested as occurring on regional scales. However, it is unclear how widespread this phenomenon is and, if like mercury and other pollutants, there is free transport of microplastics through the atmosphere that enables trans-continental movement.

Steve Allen and colleagues collected atmospheric microplastics at the high-elevation Pic du Midi Observatory in the French Pyrenees, southern France, and used atmospheric transport modelling to understand the potential sources and paths of these particles. Air masses containing microplastic' particles were found to have moved around 4,550 km on average in the week before arriving at the observatory, and were projected to mainly have arrived from the west and south, over the Atlantic Ocean and Mediterranean Sea. The authors suggest that the potential sources of the microplastics may include North America, western Europe and North Africa, indicating trans-continental and trans-oceanic transport through the free troposphere (the layer of atmosphere above the clouds).

The findings suggest that regions with little local plastic usage could be impacted by microplastic source regions located far away

Record profits for foreign-owned pig conglomerate, recently "gifted" with major grant from Canadian taxpayers to help with its Manitoba operations.

 

Below is a financial statement posted on the company website.

It was recently announced that the governments of Canada and Manitoba were "investing" $2.2 million in three agricultural research projects, to be conducted by the Dutch-based conglomerate, Topigs Norsvin Canada (TN), that will "enhance the competitiveness of Manitoba pork producers."

(And TN, too, no doubt!)

The announcement came despite opposition to a recently approved TN project to build major pig barns near the southern Manitoba community of Plumas. It drew the outrage of many of those residents, along with the citizen group, Hogwatch Manitoba. 

Flooding caused by rapidly expanding hydroelectric dams in the tropics is pushing many jaguars and tigers to the brink of extinction

New research just published, finds hydropower development to satisfy the growing human demand for energy has become one of the major drivers of habitat loss, fragmentation, and degradation everywhere. The dams create massive reservoirs, which drown out the homes of many creatures, including these top predators.

The scientists found no less than 164 dams intruding on more than 25 thousand square kilometres of jaguar range in Latin America. Sadly, plans show that number could well triple into the future.

Four hundred and twenty-one dams we’re found to be ruining or damaging almost 14 thousand square kilometres of tiger habitat in Asia.

While only forty-one dams are planned in the territorial range of tigers, they will still infringe on conservation areas considered important for their conservation.

Researchers conclude that, even though the risks such projects pose to both land habitat and freshwater biodiversity are already known, they’re rarely taken into account.

As a result of their findings, just published in the journal “Communications Biology,” they call for “a more cautious pursuit of hydropower in topographically flat regions, to avoid extensive habitat loss and degradation.”

Melting glaciers could create new habitats for Pacific salmon

Nature Communications

Melting glaciers in western North America could create new habitats for Pacific salmon over the next century, a modelling study in Nature Communications suggests. 

Migratory Pacific salmon are one group of species whose abundances have dramatically shifted in response to changing climate patterns, however, the warming of Arctic and subarctic streams, in combination with glacier retreat, could create potential new habitats for salmon. Previous work has observed the colonization of newly de-glaciated streams by salmon, but predicting future shifts in salmon habitat across regions has been difficult. 

Kara Pitman and colleagues modelled glacier retreat under different climate change scenarios for a 623,000 km2 region of western North America. They quantified emerging streams created by glacier retreat, which they combined with stream gradient-based salmon habitat models. 

By 2100, the authors project that approximately 6,000 km of new streams will be accessible to Pacific salmon and, of this newly accessible habitat, nearly 2,000 km will be suitable for spawning and juvenile rearing. 

The authors note that glacier retreat is only one consequence of climate change and other climate-induced effects such as ocean heat waves, sea-level rise and extreme flood events could all cause widespread declines in salmon abundance. 

Glacier retreat also creates new prospects for industries such as mining, which can degrade salmon habitat. Understanding the timing and location of emerging salmon habitat is critical to informing conservation planning and to avoid degradation of future salmon habitat, the authors conclude.

Hog Watch Manitoba decries $2.2 million government subsidies to Topigs Norsvin - a foreign company, despite community concerns and opposition.

Winnipeg (December 2, 2021) – Hog Watch Manitoba shares the anger and frustration felt by many Plumas area residents who fought the approval of two large hog facilities in their municipality this past summer. Not only are they angered by the decision to go ahead with these two huge barns in the face of so much local opposition but now to find that their tax dollars are going to pay for it, is outrageous.  

They dispute the company’s claim this is being built in an isolated area as there are 8 homes in less than a 3 km circumference of one barn and the other is in close range to the Big Grass River and marshland, environmentally sensitive areas. 

There were 52 letters of opposition to the proposal and numerous presentations made expressing legitimate concerns about health impacts from toxic emissions from barns and open manure lagoons, and water consumption of 44,000 gallons a day depleting local water resources.

Hog Watch Manitoba is calling on both the provincial and federal governments to review their decision and if it cannot be reversed, provide local residents with assurances that toxic odour problems and water shortages will not be allowed. Mitigation such as air scrubbers on barns and water rights being enshrined should be imposed.

Arctic rainfall predicted to increase faster than expected

The amount of rainfall in the Arctic may increase at a faster rate than previously thought, according to a modelling study published in Nature Communications. The research suggests that total rainfall will supersede snowfall in the Arctic decades earlier than previously thought, and could have various climatic, ecosystem and socio-economic impacts.

The Arctic is known to be warming faster than most other parts of the world, leading to substantial environmental changes in this region. Research suggests that there will be more rainfall than snowfall in the Arctic at some stage of the 21st century, but it is not yet clear when this shift will occur.

Michelle McCrystall and colleagues used the latest projections from the Coupled Model Intercomparison Project (CMIP6) to assess the changes in the Arctic water cycle by the year 2100. The authors found that precipitation, such as rainfall and snowfall, is projected to increase in all seasons. Rainfall is projected to become the dominant form of precipitation one to two decades earlier than previous models suggested, depending on the season and region, linked to increased warming and a faster decline of sea ice. For example, previous models projected the central Arctic to transition to a rainfall-dominated region in 2090, but it is now predicted to transition in 2060/2070. The authors suggest that a transition to a rainfall-dominated Arctic could occur at lower temperature thresholds than previous models projected, even at 1.5°C warming in some regions, such as Greenland.

The authors argue that more stringent climate mitigation policies are required, as a rainfall-dominant Arctic would have impacts on ice sheet melting, rivers and wild animal populations, and have important social-ecological, cultural and economic implications.

THE HIGH-MAINTENANCE POLLUTING PORK INDUSTRY BELLIES UP to THE TAXPAYER TROUGH ONCE AGAIN.

 Manitoba/Canada News Release

GOVERNMENTS INVEST IN "INNOVATION" TO "HELP INCREASE COMPETITIVENESS AND SUSTAINABILITY OF PORK PRODUCERS"

The governments of Canada and Manitoba are investing $2.2 million in three agricultural research projects, to be conducted by Topigs Norsvin Canada (TN), that will enhance the competitiveness of Manitoba pork producers by improving the precision feeding of sows and promoting higher animal welfare standards, Federal Agriculture and Agri-Food Minister Marie-Claude Bibeau and Manitoba Agriculture and Resource Development Minister Ralph Eichler announced today.

"These innovative projects will give the pork industry more tools in their sustainability toolbox," said Bibeau. "They will help to improve feeding and housing for the pigs, which leads to better resource efficiency and a reduced environmental footprint for producers. Topigs Norsvin plays a big role in making Canada a global leader in swine genetics, and we are proud to support their work."

"Our government is pleased to support the work of our producers through these innovative projects that will accelerate agricultural innovation, promote knowledge transfer to producers, advance value-added opportunities, strengthen competitiveness and support sustainable agricultural development in our provincial pork industry," said Eichler. "The results of these projects will be valuable in our continuing efforts to strengthen the sustainability of our provincial pork industry."

The three research projects, which will help the pork industry be more environmentally and economically sustainable, will focus on:

improving competitiveness and sustainability of pork production through increased feed efficiency, improved carcass quality and higher animal welfare standards by innovative application of microbiome profiling, computer tomography and genomics;

advancing sow reproductive knowledge and management practices for optimal lifetime productivity and embryo transfer success; and innovative application of artificial intelligence, machine learning, behavioural science and genomics to enhance resource efficiency for environmental sustainability of sow farms in Manitoba using welfare friendly production.

Funding is provided by the Ag Action Manitoba Program-Research and Innovation, through the Canadian Agricultural Partnership. The funded research will be beneficial to the province's first-of-its-kind sustainable protein strategy, ensuring Manitoba producers are well-positioned to remain leaders in plant and animal protein development in the face of increased global demand for high-quality protein, the minister added.

A key element of the strategy includes using innovation to grow livestock herds for animal protein and new acres for plant protein, while ensuring Manitoba remains a strong environment for investment and is responsive to the needs of producers.

TN is establishing an over $30-million new research and development facility in Plumas, Manitoba. It is to be completed by the end of 2022 and is aimed at sow management, where the funded projects will be conducted and results shared with industry stakeholders. The first of its kind in the world, these projects will utilize leading-edge artificial intelligence, computer vision, behavioural research, and precision feeding to generate a database comprised of important animal health and welfare data.

"Topigs Norsvin continuously monitors international developments in the pork industry and prides itself as a leader in the sector," said Hans Olislagers, Chief Technical Officer, Topigs Norsvin. "Implementation of loose housing of sows during farrowing is already legislated in several countries and we recognize our responsibility to breed and select pigs while maintaining the integrity of animal welfare. This assures our customers that our genetics will fit the housing systems and market demands of the future."

The Canadian Agricultural Partnership is a five-year, $3-billion investment by Canada's federal, provincial and territorial governments to strengthen and grow Canada's agriculture, agri-food and agri-products sectors. This commitment includes $2 billion for programs cost-shared by the federal, provincial and territorial governments that are designed and delivered by provinces and territories.
