How Weather affects Agriculture
Have you ever noticed that prices on dairy, fruits and vegetables seem to skyrocket sometimes during the year? This is because of the weather changes we experience everyday. Do you ever think about how weather is affecting your food or the clothes you will buy? Weather affects where and how your food is grown and how the products grown that are used to make the clothes we wear everyday. Hello I am Mason Wilson and I am from the River Valley FFA and I am doing my speech on weather and how it affects agriculture.
Farmers need certain weather to grow their crops. They need a place where they can
have the sunlight the crop fields need and rain to help the plants grow. And there can be
many problems resulting from bad weather conditions such as droughts, storms,
tornadoes and many more. If a farmer’s field suffers from a drought the plants will
become extremely brittle and they will break very easily and the plants will eventually die from not having any water and the longer a drought the
more chance of a fire breaking out. Last year in 2009 northern California lost 272,000
acres of land because of 82 fires. By the end of 2009 there were a total of 77,315 fires
having burned 5,914,821 acres.
Rain has a lot of influence on the crops: too much rain can damage the crops, not
enough rain can make the crops dry, different crops need more or less water and if they
didn’t get them they fail to grow and we don’t get crops and the prices of what is left will
go up.
Did you know that 18 percent of Texas is under cloud-seeded skies because local
farmers and businesses want more rain? Cloud seeding is when scientists put little
particles of silver iodide in a cloud, water droplets form around them, and drop out of the
cloud as rain. It works in a lab, but there is almost no way to tell how much it works in
the outdoors. This was extremely popular until the 1970 when it was found out the US
was using this technology against the Vietnamese.
“There are basically several brands of weather modification.
Hurricane mitigation technology has been proposed but not yet attempted, like putting oil
slicks on the ocean to reduce evaporation or putting a giant gel in the ocean that sucks up
moisture from the atmosphere and adds it to the ocean.
Bill Gates has patented a hurricane modification technology which pumps cold water up
from the bottom of the ocean, because hurricanes are fuelled by warm water.
Geo engineering is the really large scale, sci-fi projects like putting 16 trillion tiny discs
in space to reflect about 2 percent of sunlight back into space.
The most popular idea is that of the so-called “man-made volcano.” It means spraying
sulfur dioxide up into the sky and that would mimic what happens when big volcanoes
erupt and sulfur dioxide acts like a thin sheet in the atmosphere that could block two to
four percent of sunlight. When big volcanoes erupt, the world cools by 2 to 4 degrees.
But this could also damage the Ozone layer and what happens if a volcano erupts after
you have sprayed sulfur dioxide? Are you then looking at a new ice age?” - Allianz.com
The high winds of a tornado will easily snap the crops and rip them right out of the ground destroying many acres of farm land. It is almost guaranteed that the prices on tomatoes, strawberries, may go up a little bit as a result of some crop loss they’ve had in Florida. The Florida orange companies haven’t fully recovered from the hurricane damage in 2004 and 2005.
Weather is both good and bad when it comes to the prices of food. If there is normal
weather all year than the prices will be lower because there will be more crops that
survived and the producers won’t have to charge more to make up for lost profit. If there
is bad weather prices will go up because the producers won’t be able to make enough
money to replace all the crops they may have lost due to the bad weather. Australia has
seen bad droughts six years running, and last year there was major flooding in Argentina.
Since both of these countries are major dairy exporters, milk and butter the prices are
much higher than they used to be. In China prices of vegetables are really high because
of really bad snowstorms. In Beijing prices of vegetables like cabbage, egg plant, and
cucumber have risen 30%. "Since Jan 3, some vegetable growers started to complain that
the plants in their green houses have withered and rotted due to the weather," said Sun
Zhigang, director of the agriculture information center in Shouguang. Prices will hopefully go down so that people can afford the food. If bad weather stays away farmers will have better crop growth and there will be a lot of products when they are ready to be sold and the prices will be low because there is enough food to go around.
