- Sparse vegetation ( very little vegetation ) and
- Limited population of people and animals.
- Agriculture and
- Survival is very difficult.
- North Africa
- In Asia like India ( Rajasthan where Thar desert is present ).
GENERAL CHARACTERISTICS OF DESERTIFICATION
- American southwest
- North and South Africa
- South Asia
- 20% of Earth’s surface.
- The percentage is increasing day by day.
- Very dry , extreme cold and hot on daily basis
- Precipitation is less than 25 cm in a year.
- Temperature and
- Precipitation is unpredictable each year.
# Soil : – Exposed
- Very sparse plant cover.
- Cactus is usually found
- Plants shed leaves which grow only in the short rainy season.
# Fauna : –
They are small in size like : –
- Desert tortoise rodents
- Camels are large
- They all have a special feature that they can conserve water.
Given below are the causes and effects of desertification.
CAUSES OF DESERTIFICATION
Natural and Anthropogenic activities are the main causes of desertification.
There are 2 types of causes and they are : –
- direct and
- indirect causes.
DIRECT CAUSES : –
- Includes climate and human activities like: –
- Inappropriate use of irrigation technology.
INDIRECT CAUSES : –
- Includes population pressure
- Inequitable sharing of resources i.e no sustainable development control.
- Over-Population due to migration.
- Loss of Habitat.
- Loss of life and property.
- No agriculture is possible.
- Barren land and water scarcity.
- Loss of biodiversity
- Exploitation of natural resources.
- Change in climate due to increased pressure and temperature in that particular area.
WHAT ARE THE GLOBAL MEASURES BEING TAKEN TO PREVENT DESERTIFICATION ?
Since you know the causes and effects of desertification then you must know the measures taken to prevent desertification and they are : –
- Improved early warning system.
- Prevention of soil erosion
- Water resource management.
- Sustainable forest and livestock management.
