Explained: Why is this season’s forest fires in Uttarakhand worrisome?
May 19, · Natural Causes. Lightning is the biggest natural cause of forest fires. The different lightning strokes of varied electric voltages cause fire through directly igniting vegetation with high currents. Lightning fires are always more common immediately after dry seasons when vegetation is . Dec 05, · The other 85 to 90 percent result from human causes, including unattended camp and debris fires, discarded cigarettes, and arson. Naturally .
One of the most prevalent causes of global deforestation and destruction of wildlife is fire. In the United States in particular, fire has ravaged many areas of both forest and countryside. Forest or wildlife fires spread at different speeds depending on vegetation, weather conditions, and physical features.
Discovered fossil charcoal indicate that forest fires are not new to modern history as some date back to over one hundred million years ago. The Earth is said to be a fundamentally flammable planet because of the causss of vegetation rich in carbon, dry climates, oxygen in the atmosphere, lightning, and volcanic activities among others.
Human activities near or within forested areas are the number one cause of forest fires. Smoking near vegetation can cause a widespread fire when a smoker throws a cigarette into vegetation without completely extinguishing its burning butt. While most smokers throw lit cigarettes innocently, their actions have caused several forest fires throughout history.
Some fires may take a few hours before being noticed as the fire starts small and spreads slowly at first before gaining momentum. Equipment such as machinery used in logging and hunting can also cause fires. Bullets hitting on some dry vegetation may result in fires. Petroleum products used in logging equipment can cause fires when there is a leak onto the vegetation.
Other causes include campfires that are not well monitored or put off entirely. Electric faults from facilities or electricity plants near forests can also cause fires. In some extreme cases, people have deliberately caused fires how to get on anti anxiety medications hunting to corner wild animals while others burn forests to clear the way for agriculture or development activities.
Lastly, some people just start fires without any reason arson. Lightning is the biggest natural cause of forest fires. The different lightning strokes of varied electric voltages cause fire through directly igniting vegetation with high currents. Lightning fires are always natudal common immediately after dry seasons when vegetation is still dry.
Lightning fires destroy more vegetation than human-caused fires. This is because lighting fires occur in remote areas far from human presence and are not notice in time, unlike fires caused by human activities. Lightning caused fires also occur in rough terrains and dangerous places which makes it hard for fire suppression equipment and personnel to reach the fire on time.
In rare occurrences, volcanic activities such as eruptions and lava flow can cause fires which are difficult to put out because of the lava flow and other associated risks.
In most cases, firefighters try to foerst a buffer zone where they can manage the fires. Fauses combustion of dry leaves and vegetation may also be responsible for some fire outbreaks.
Most natural fires are usually monitored and allowed to burn, with the aim of balancing a forest's ecology. Vegetation may also be burned occasionally in order to balance species. Authorities have how long to broil tilapia fillets awareness campaigns on the causes of fires to reduce human fire fire incidences.
In some cases, firefighters burn sections of forest vegetation to control possible fires in the future by creating buffer zones. Wildfire suppression can be done in various ways. Simple techniques such as throwing layers of soil can be used. In some cases, unmanned aerial planes can be used to natjral water and fire retardants. Bushfires are often incredibly destructive.

Nov 27, · *Source: data based on Wildland Fire Management Information (WFMI) and U.S. Forest Service Research Data Archive. Lightning is one of the two natural causes of fires. Nature and Wildfire. Lightning is described as having two components—leaders and strokes. The leader is the probing feeler sent from the cloud. Apr 09, · Fires in the Sakha Republic, August Pierre Markuse / Wikimedia Commons / CC BY Fires are a natural part of wild nicefreedatingall.com and white spruce trees in . Feb 27, · Forest fires can help wildlife return to the forest. When the forest floor becomes littered with debris, then it can drive some animals away from their natural habitat. The difficulty in moving along the undergrowth causes them to look for alternative options, which can disrupt other sensitive ecosystems that are not used to the presence of the.
Due to this expected growth, there is pressure throughout the world for higher agricultural production and reliable crop status information. To achieve these objectives, improved management of the world's agricultural resources are required, especially in developing countries. To make this happen it is first necessary to obtain reliable crop status information on not only the types, health status, quality, quantity and location of these resources.
Geographic Information Systems GIS tools and online web resources can help farmers to conduct crop forecasting and manage their agriculture production by utilizing multispectral imagery collected by Satellites, fix wing Aircraft or Unmanned Aerial Vehicles UAV's and processed to provide NDVI and other vegetation soil indices, to identify crop stress. The ability of GIS to analyze and visualize agricultural environments and workflows has proven to be very beneficial to those involved in the farming industry.
Pansharpened vegetation indices can be delivered with a resolution of 30cm, 40cm or 50cm, providing greater details for analysis. Because the Sentinel-2 Satellite Imagery, provided by the European Space Agency ESA , can be downloaded for free and requires only vegetation and soil index image processing, providing a cost effective Ag solution, covering large areas around the globe, were 10m resolution is acceptable or desired due to limited financial resources.
The vegetation indices provided will cover multispectral reflectance values from 0. For areas throughout Africa and other regions around the World, experiencing agriculture production problems in quality or quantity, the Sentinel-2 Satellite sensor can support the regional farmers and farm cooperatives and other organizations, with timely and critical information. The agriculture, forestry and environmental industry are using the standard NDVI index for many years but with the availability of hyperspectral sensors and high resolution Satellite sensors, such as WorldView-2 and WorldView-3 , utilizing an expanded Multispectral reflectance range, SIC can provide a variety of vegetation indices to filter the correct band combinations for vegetation, soil and environmental analysis to support crop, forest and environmental project management.
