Is it possible to reduce the amount of phosphorus being released from agricultural land and into waterways, such as Lake Winnipeg, during the spring melt? It’s a question UWinnipeg Professor Dr. Darshani Kumaragamage, Department of Environmental Studies and Sciences, and her research team are trying to answer. In most parts of the world, erosion, and rain-driven runoff are the major pathways by which phosphorus from agricultural fields enter waterbodies. However, in cold climates like the Canadian prairies, flooding-induced phosphorus loss during the snowmelt period is the dominant transport mechanism of phosphorus from agricultural lands to water bodies.
Spanish farmers protest against plans to curb water supply for irrigation
Thousands of farmers protested in Madrid on Wednesday over Spain's plan to reduce the amount of water taken from the Tagus river to irrigate agricultural land in the country's southeast. Spain experienced its hottest year on record in 2022. The heat, accompanied by a long drought throughout most of the year, caused reservoirs to fall to critical levels. Environment Minister Teresa Ribera said on Tuesday the curbs were necessary to prepare the country for the effects of climate change.
BLOG: An Ontario problem, a prairie concern
In the spring of 2018, Health Canada proposed a ban on all agricultural uses of two insecticides, thiamethoxam and clothianidin. Health Canada scientists said the insecticides, known as neonics, were accumulating in ponds, creeks and other water bodies near agricultural land. The concentrations were harmful to midges and mayflies and therefore posed a threat to birds and other animals that rely on the insects for food.
Water Security Agency Holds Open House Events For Lake Diefenbaker Irrigation Projects
The public is invited to take part in a couple of open house events this week to learn more about the Lake Diefenbaker Irrigation Projects. The 10 year multi-project is expected to provide a major boost for the Province's agriculture sector. Once completed, the Lake Diefenbaker Projects will provide over 500,000 acres of agricultural land in southern and central Saskatchewan with water. Patrick Boyle, the Executive Director of Communications with the Water Security Agency, says they are holding a couple of open house events this week so that people have a better understanding of the work that is being planned and the impact it will have for the areas.
