Canada Hundreds of people representing fire management agencies across the country are in Kelowna this week for the Wildland Fire Conference.
The conference brings together researchers, practitioners, managers, and firefighters all under one roof to discuss and explore issues within wildfire fighting.
Fire Research Coordinator with BC Wildfire Service and Co-Chair of the conference, Daniel Perrakis says presentations and sessions cover the whole broad scope of wildland fire management.
Including suppression, suppression equipment, techniques, as well as fire ecology, fire effects on the community, and planning, from the scientific to the social to the economic aspects
Kendrick Brown, Research Scientist with Natural Resources Canada and Co-Chair of the conference says this year’s theme is Building Resilience.
We have changes in climate, changes in forest conditions, we have increased public expectations and as things change, wildfire has the potential to change likewise, he said So its very important that communities and individuals are able to position themselves to proactively respond to and cope with this change
One session earlier today focused on the Fort McMurray wildfire, including the wind and drought conditions that contributed to it, the community response, where the community is now and any lessons to be taken away.
Tomorrow, a firefighting aircraft will hold a demonstration in the skies above West Kelowna, dropping water on a hillside in the Smith Creek area. Public lectures are also being held at the downtown Kelowna public library throughout the week.
The conference happens every two years.
Winters have started approaching the northern region of India that also includes Delhi-NCR along with Punjab and Haryana. Due to this, minimums have also started dropping in many parts of North India including Delhi and NCR. In fact, as per the temperatures recorded on October 15 and October 17, the minimums ofDelhi and NCR went down to 17°C.
As per experts, an increase in the pollution level normally occurs during the winter months. However, there are a few reasons that could enhance the pollution level in Delhi and the adjoining areas. The very first reason that can be attributed to an increase in pollution level in the national capital is crop fires in the neighboring state ofHaryana andPunjab.
These two states lie in northwest proximity of Delhi and normal pattern of winds during this season is northwesterly. These winds drag the smoke and fine particles of the burnt crop and mix them with Delhis atmosphere. Moreover, the temperatures also start dipping, therefore, the air near the earths surface tends to condense leading to formation of haze.
Whenever the winds are light or calm, these air pollutants get mixed with the haze or mist and forms a blanket of smoke haze which remains suspended for few hours in the mornings. Thereafter, the haze disappears as the sun rises and temperatures increases during the day.
But as the winter progresses in the month of December and January, the duration of haze, mist or fog gets extended and these pollutants remain suspended in the atmosphere for longer duration of time. Other factors including the smoke emitting from vehicles and factories and dust from construction sites also add to the rising pollution levels.
Sometimes this situation can continue for days altogether. However, relief is expected only when a strong Western Disturbance gives rain over the region. It is then that these pollutants settle down for a few days.
Another criterion which reduces the pollution levels is the strong and moderate dry winds from northwest or west which carry away these pollution particles. In a nutshell, it can be said that in October, intensity and duration of pollution remain less though increases in November as winters sets in.
