What are the causes of desertification in California?

In this article, we enumerate the various causes of desertification in the State of California, USA. Furthermore, we also discuss how desertification is linked with anthropogenic activities, and what steps can be taken in order to impede the spread.

What are the causes of desertification in California?

The following issues are the causes of desertification in California:

  • Overgrazing
  • Overuse of Pesticide
  • Urbanisation
  • Deforestation
  • Forest fires and other natural disasters
  • Excessive farming

What is Desertification?

Desertification refers to the deterioration of land in arid and semi-arid climates across the world. Climate change processes such as drought and wildfires, as well as human actions such as deforestation and agriculture, are to blame. 

Finally, in many nations across the world, complex interplay between physical, biological, social, cultural, and economic elements create desertification. 

Excessive farming and California’s drought crisis have resulted in a significant loss of livable land, paving the path for a desertified state. 

Desertification destroys 12 hectares of land every year throughout the world, rendering such regions unusable.

Nations all across the globe are working to tackle the phenomena of desertification, with worldwide measures planned – mostly through the United Nations – to halt the ever-worsening process of land degradation.

Desertification in the USA

While deserts naturally extend and decrease, it is vital to note that desertification is not the same as this natural cycle. 

Desertification is also far from being a new global crisis: it wreaked havoc on ancient empires such as Sumeria, Babylon, and Rome. 

Unfortunately, there is no single cause of desertification that we can point to; rather, it is a combination of climate and our own mistakes, ignorance, and behaviours.

Desertification is mostly caused by land misuse and unsustainable agricultural practices (overcropping, overgrazing, inadequate irrigation, and deforestation), which result in the loss of natural flora and good soil. 

A growing human population and urban dwelling area, as well as a low priority given to environmental preservation initiatives, all play a role.

The world’s five major deserts, including the: 

  • Sonoran Desert in northwest Mexico and the Southwest United States,
  • Atacama Desert in South America, the Kalahari Desert in Southern Africa, 
  • most of Australia, and, 
  • The Sahara, Arabian, Great Indian, Taklimakan, Gobi, and the deserts of Iran and the former Soviet Union, are currently the most endangered regions.

Based on climate and soil type, seventeen states in the Western United States can be classified as arid, semi-arid, or dry sub humid, making them subject to desertification. 

New Mexico, Texas, and the Navajo Indian reservation in New Mexico and Arizona are the most severely impacted places in the United States. 

Overgrazing, which has resulted in wind and water erosion, and inadequate irrigation are the major causes of desertification in the United States, and scientists estimate that the damage will not be repaired naturally in the next 100 years.

The United States recognised desertification as a national concern with the founding of the Soil Conservation Service during the devastating 1930s dust bowl, and the government began providing financial assistance and resources to put suitable agricultural practices in place. 

State and federal authorities, as well as non-profit groups, collaborate with private ranchers, farmers, and developers to create technology that decrease soil loss, increase irrigation, and utilise renewable energy sources.

What are the causes of desertification in California?

The following issues are the causes of desertification in California:

  • Overgrazing
  • Overuse of Pesticide
  • Urbanisation
  • Deforestation
  • Forest fires and other natural disasters
  • Excessive farming

WE shall discuss these in more detail below.

Overgrazing

Animal grazing is a major issue in many locations that are transitioning to desert biomes. 

Overgrazing by too many animals in specific areas makes it harder for plants to recover, which harms the biome and causes it to lose its previous green splendour.

Overuse of Pesticide

Excessive use of fertilisers and pesticides to increase crop yields in the near term frequently results in substantial soil degradation.

In the long run, this area may transition from arable to desert, and after a few years of intensive farming, it will no longer be viable for farming since the soil has been harmed too much.

Urbanisation

People may be compelled to go through and harm plant life as a result of development. It can also affect the soil by introducing chemicals and other potentially harmful substances. 

Desertification occurs when there are fewer places for plants to grow as areas become increasingly urbanised.

Deforestation

When people seek to settle in a particular region or require trees to build houses or do other chores, they are contributing to the problem of desertification. The remainder of the biome cannot exist without the presence of plants (particularly trees).

Forest fires and other natural disasters

Wildfire has been a major issue in California, making it one of the most significant causes of desertification. Until now, 4 million acres of land in California have been burnt due to wildfires.

Natural calamities, such as drought, can cause harm to the land in some situations. There is not much individuals can do in those situations besides labour to assist rebuild the land once it has been harmed by nature.

Excessive farming

Some farmers are not sure how to make the most use of their property. Before going on to another area of land, they may virtually strip the land of everything it possesses. 

Desertification becomes more of a reality for the region that is utilised for farming when the soil is stripped of its nutrients.

Combating Desertification

Since desertification is a serious issue, it is important to take the right steps in order to prevent it from becoming an unmanageable issue.

Some of the ways to combat desertification are:

  • Policy Changes Related to How People can Farm
  • Policy Changes to Other Types of Land Use
  • Education
  • Technology Advances
  • Restricting Mining Practices
  • Putting Together Rehabilitation Efforts
  • Reforestation
  • Sustainable Practices to Prevent Desertification From Happening

We shall discuss these in more detail below.

Policy Changes Related to How People can Farm

Policy changes relating to how frequently individuals may farm and how much they can farm on particular areas might be implemented.

This should be done in nations where policy change will really be imposed on persons in the country to assist lessen the difficulties that are typically connected with farming and desertification.

Policy Changes to Other Types of Land Use

If people are utilising land to acquire natural resources or to develop it for people to live on, the regulations that regulate them should assist the land thrive rather than permitting them to further hurt the land. 

The policy modifications might be broad or specific to the sort of land use in question.

Education

Education is an extremely vital tool in developing nations for helping people learn the best ways to utilise the land they are farming on. More land will be protected from becoming desert by teaching people on sustainable practises.

Technology Advances

Most of our environmental issues may be solved via research, and this holds true for desertification as well. Attempting to avoid desertification might be challenging in some instances. 

In some circumstances, study and use of cutting-edge technologies are required to push the boundaries of what we now know about the causes of desertification. 

We may be able to find additional strategies to prevent the problem from becoming an epidemic as technology advances.

Restricting Mining Practices

Mining frequently entails the abolition of big swaths of land. As a result, governments should control it in order to preserve nature reserves and protect the natural habitats of many animals and plants. 

As a result, less area will remain arid, and the problem of desertification will be addressed to some extent.

Putting Together Rehabilitation Efforts

There are certain steps we can take to repair land that has already been driven into desertification; it simply requires some time and money. 

By putting these together, we can prevent the issue from becoming even more widespread in the areas that have already been affected.

Reforestation

Reforestation should be explored in regions that have previously been subjected to deforestation. 

Planting trees in those locations is critical because they act as natural carbon dioxide storage spaces, slowing global warming and contributing to the preservation of natural equilibrium.

Using those lands for other uses, on the other hand, may eventually transform them into arid terrain. As a result, planting trees in impacted regions not only prevents desertification, but also combats other environmental challenges.

Sustainable Practices to Prevent Desertification From Happening

There are several sustainable practices that may be used to address activities that may be contributing to desertification. We can avoid turning the entire globe into a desert by incorporating these into what we should be doing with land.

Desertification is a major issue that must be handled immediately, and if we do so now, we can avoid worse issues in the future. We now have the tools we need to properly navigate the processes of desertification by taking a critical look at them.

Conclusion

In this article, we covered the various reasons that are responsible for the progression of desertification in the state of California, USA.

Furthermore, we also discussed the various changes that should be made in desertification-sensitive areas that will help to impede and prevent any further spread.

FAQs

What are the effects of Desertification?

  • If a region becomes a desert, it becomes very hard to cultivate significant crops there without the use of specific technology.

    Due to the high cost of attempting to do so, many farmers will be forced to sell their property and leave the desert areas.
  • Crop yields are one of the most significant effects of desertification. When terrain transitions from arable to desert, it is frequently no longer suited for cultivation.

    As a result, many farmers’ livelihoods may be jeopardised, as farming is frequently their primary source of income. If their land gets parched, they may no longer be able to produce enough food harvests to support themselves.
  • Without farms in these locations, the food that these farms provide will become much scarcer, and the people who live in these areas will be much more inclined to resort to desperate measures to alleviate hunger.

    Animals will become hungry as well, causing an even worse food deficit.
  • Flooding is far more likely when there is not any plant life in the region. Not all deserts are dry; those that are moist might see a lot of floods since there is nothing to keep the water from accumulating and spreading everywhere.

    Flooding may also have a detrimental impact on the water supply, which we shall talk about next.
  • When a region becomes a desert, the water quality deteriorates far more than it would otherwise.

    This is because plant life serves an important part in keeping the water clean and clear; without it, keeping the water clean and clear becomes much more difficult.
  • Animals and humans will migrate to other locations where they can survive if areas begin to become desert.

    This leads to overcrowding and overpopulation, which will, in turn, perpetuate the cycle of desertification that began it all in the first place.
