Which states in the United States are at very high risk for desertification?

More than 30 percent of North America is comprised of arid or semi-arid lands, with about 40 percent of the continental United States at risk for desertification [source: U.N.]. The most severely affected areas in the U.S. are in New Mexico, Texas and on the Navajo Indian reservation in New Mexico and Arizona.

Where is desertification most likely to occur?

Africa is the continent most affected by desertification, and one of the most obvious natural borders on the landmass is the southern edge of the Sahara desert. The countries that lie on the edge of the Sahara are among the poorest in the world, and they are subject to periodic droughts that devastate their peoples.

How does climate change affect desertification?

Climate change may exacerbate desertification through alteration of spatial and temporal patterns in temperature, rainfall, solar radiation and winds. In Southern Europe, higher temperatures and more frequent drought are expected to reduce water availability, hydropower potential, and, in general, crop productivity.

How does climate change affect cattle?

The direct effects are due primarily to increased temperatures and frequency and intensity of heat waves. These environmental conditions can affect livestock health by causing metabolic disruptions, oxidative stress, and immune suppression causing infections and death.

What states will survive climate change?

The five best states for climate change

• Michigan.
• Vermont.
• Pennsylvania.
• Colorado.
• Minnesota.
• Florida.
• Mississippi.
• Louisiana.

What states will be affected by global warming?

California, Florida, Georgia, North Carolina, Oregon, Texas and Washington are expected to experience all five major climate change categories over the next few decades. Not surprisingly, all of those states also have Climate Change Risk Index scores higher than the overall U.S. average.

What are the main causes of desertification?

‘Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification. removal of the natural vegetation cover（by taking too much fuel wood）, agricultural activities in the vulnerable ecosystems of arid and semi-arid areas, which are thus strained beyond their capacity.

What are the causes and effects of desertification?

Desertification is the degradation process by which a fertile land changes itself into a desert by losing its flora and fauna this can be caused by drought, deforestation, climate change, human activities or improper agriculture. Desertification is a process of degradation of the land.

What is global warming mention its causes?

Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.

How does global warming affect livestock?

Climate change impacts livestock directly (for example through heat stress and increased morbidity and mortality) and indirectly (for example through quality and availability of feed and forages, and animal diseases). At the same time, the livestock sector contributes significantly to climate change.
