Diseased Corn due to Drought

Diseased Corn due to Drought | The Impacts of Droughts | Scoop.it

Crops have been suffereing due to the drought, not only because they need water to survive, but because they are more succeptable to disease in droughts. The drying and cracking of the corn kernels allows fungus to intrude and infect the corn. This fungus is toxic and not edible.

2012 drought: Pick your poison

2012 drought: Pick your poison | The Impacts of Droughts | Scoop.it

Droughts can cause certain fungus and bacteria to infect plants such as corn. Nitrate, which is usually absorbed by plants and converted in photosynthesis, cannot be useful unless there is water. Therefore there is high concentrations of nitrate in the soils and plants in drought areas. Fungus can get into the cracks formed in corn kernels during a drought which is toxic for humans and animals. Cows have been getting sick from the infected crops.

Climate change could cripple southwestern U.S. forests: Trees face rising drought stress and mortality as climate warms

Climate change could cripple southwestern U.S. forests: Trees face rising drought stress and mortality as climate warms | The Impacts of Droughts | Scoop.it

The new Forest Drought-Stress Index will help scientist be able to more realistically predict the effects of droughts on different ecosystems. The atmospheric demand of water is directly related to the temperature. This literally sucks all of the moisture out of the plants and soil, causing a drought in severe high temperatures.

My Scoop on the Impact of Droughts

My Scoop on the Impact of Droughts | The Impacts of Droughts | Scoop.it

     There are both positives and negatives associated with droughts. The lack of water obviously can kill plants but the dead plants can also be beneficial. The negative thoughts related to droughts are sometimes misleading because droughts can actually cause an influx of organic matter into the soil. 

     The negatives associated with droughts include plant loss, nutrient depletetion, infection of plants and humans by fungus and disease. Plants need the water and nutrients supplied in moist soils to survive. Even though the nutrients are accessible, the lack of water makes it impossible for these nutrients to be converted to sugars and necessary nutrients for thriving plants. Humans cannot consume these plants that contain the nonconverted nitrates making the plants inedible. Besides the lack of conversion of nutrients, droughts also attribute to drying out the kernals of corn, allowing fungus to grow inside. Drought contributes to many negative effects not only on the plants but the entire ecosystem.

     Despite the negative conotation associated with drought, it has some positive environmental effects. When trees and other plants die due to drought, they decompose into organic matter. Plants can benefit from this influx of organic matter. As well as contributing organic matter to the soil, these dead trees can provide habitats for birds, insects, and small animals. Their structure also helps to prevent erosion.

Over 300 Million Trees Killed By the Texas Drought

Over 300 Million Trees Killed By the Texas Drought | The Impacts of Droughts | Scoop.it

A severe drought in Texas caused over 300 million trees to die in rural areas. One region, "Brazos Valley region being the hardest hit" (Henry). They lost nearly 10 percent of their trees; but these dead trees can be beneficial because they provide habitats for birds, insects, and other wildlife. The trees also provide nutrients to the soil and help prevent erosion. The downside to all of the dead trees is the release of carbon which can be fuel for wildfires.
