California is an epitome of Modern Agriculture practices. Farming started in the mid 19th century and by the early 21st century, doomed.Desert everywhere.

Desertification is defined as the deterioration of land in typically arid areas due to changes in climate and human activities. In the United States, desertification is typically caused by poor farming practices and the conversion of grazing areas to cropland.

In order to salvage lands affected by desertification, farmers begin to invest more in irrigation, which in turn diminishes groundwater resources and is the beginning of long-term impacts such as drought and famine. Additionally, as the topsoil becomes less nutrient rich from desertification plants become less productive and many of the ecosystem services they were providing are diminished.

Bharat is still alive after 40 years of mindless farming for two reasons:

1) Gau (Cow)
2) Traditions

Now both are diminishing rapdily. Are we expecting Sahara here? The California way!

California Desertification: How do we keep California the Golden Coast?

California has always been seen as the Golden Coast.  It is a land of plenty that supports millions of people and has an immense and productive agricultural industry, producing almost 15% of the nation’s annual crops.

But the productiveness of California has a limit, and both its climate and human overuse can distress the land beyond repair.  Desertification is the process of the loss of nutrients (top soil) to drylands, resulting in infertile land that can be easily eroded due to the lack of vegetation that would normally provide soils with the structural component to combat erosion.  Vegetation is vital to dry soils, prominent in much of the California climate, because the soils can easily be carried away by wind, or on the rare occasion of rain in Southern California, water.  Overfarming, which depletes the soils nutrients, or overgrazing, which physically strips the soil of vegetation, are two of the most common triggers of desertification.

Desertification can be a natural process too.  The United Nations Conference to Combat Desertification identifies that desertification is also due to climactic changes, where extended periods of drought or dryness can harm vegetation and leave soil dry and exposed to the elements, although some may argue that these may be anthropogenic as because of the link between global climate change and greenhouse gas emissions.

But while desertification can be a natural process, these natural processes and tendencies of Southern California are only augmented by the anthropogenic abuse of the land such as over farming and overgrazing.
