Deserts are the driest regions of the earth, where rainfall is extremely low and life is very difficult. Yet deserts are not empty wastelands. They are home to hardy plants, specially adapted animals, and people who have learned to survive and prosper in the most challenging environments on earth. This chapter studies life in two great deserts of the world: the Sahara desert in Africa and the Ladakh desert in India.
The Sahara is a hot desert, one of the hottest regions of the earth, while Ladakh is a cold desert in the high mountains of the Himalaya. By comparing these two deserts, we learn how different environments shape the lives of the people who inhabit them, and how human beings adapt to even the harshest conditions.
A desert is a region that receives very little rainfall, less than about 25 centimetres a year. Because of the low rainfall, deserts have little vegetation and few permanent streams or rivers. Deserts can be hot, like the Sahara, or cold, like Ladakh and the Antarctic desert.
Deserts cover about one-seventh of the earth's land surface. The plants and animals of the deserts have developed special adaptations to survive the lack of water and the extreme temperatures. The people of the deserts have also adapted their way of life - their homes, clothing, food, and occupations - to the desert environment.
The Sahara desert is the world's largest hot desert. It is located in Africa, and it covers about 8.5 million square kilometres, almost the whole of North Africa. The Sahara is bounded by the Atlantic Ocean in the west, the Mediterranean Sea in the north, and the Red Sea and the Nile river in the east.
The climate of the Sahara is extremely dry and hot. The days are scorching hot, and the nights can be freezing cold because the desert air holds very little moisture. The rainfall is very low, and in some parts of the desert, it may not rain for years. Because of the extreme conditions, the population of the Sahara is small, but it is growing.
The Sahara is not an empty land. About 4 million people live in the desert, mostly in the oases and the areas near the rivers. The people of the Sahara belong to different groups, including the Bedouins and the Tuaregs, who are nomadic pastoralists, and the tribes that live near the oases.
The Bedouins and Tuaregs are camel herders who move from place to place in search of pasture and water for their herds of camels, sheep, and goats. They live in tents made of animal skins, and their camels are called "ships of the desert" because they can travel long distances without water. The people near the oases grow date palms and other crops, and they trade in dates, fruits, and crafts.
The life of the people of the Sahara is closely connected to the desert environment. The camel is the most important animal, providing transport, milk, meat, and wool. The nomads move their herds according to the seasons, following the grazing grounds. The oases, with their water and date palms, are the centres of settled life.
In recent times, the discovery of oil in the Sahara has changed the life of the region. The oil revenues have brought wealth, and roads, houses, and schools have been built. However, the traditional way of life of the nomads is gradually changing, as many are settling down in the towns and oases.
Ladakh is a cold desert in the eastern part of Jammu and Kashmir, surrounded by the Karakoram range in the north and the Zanskar mountains in the south. It is at a very high altitude, and the city of Leh is the main settlement. The rivers that flow through Ladakh, including the Indus, provide water for the valleys.
The climate of Ladakh is extremely cold and dry. The altitude makes the air very thin, and the temperatures can fall below -40 degrees Celsius in winter. Because of the high altitude, the sun's rays are very strong, and there is very little rainfall. The growing season is very short, and agriculture is difficult.
The people of Ladakh include both Muslims and Buddhists, and their culture is a blend of Buddhist and Islamic traditions. The Buddhist monasteries (gompas) are the centres of religious life, and the people are known for their hospitality. The main occupation of the people is animal husbandry, and they keep yaks, sheep, goats, and cattle.
The yak is the most important animal of Ladakh. It provides milk, meat, wool, and leather, and it is used as a beast of burden to carry goods through the mountain passes. The wool of the sheep is used to make warm clothes and carpets, and the famous pashmina wool comes from the pashmina goat.
Because of the cold climate, the people of Ladakh grow only limited crops, like barley, potatoes, peas, beans, and turnips, in the short summer season. The houses are made of stones, and the flat roofs are used to dry the grains. The people depend on their animals for food, clothing, and transport.
The barren mountains and the difficult terrain make transport difficult, and the passes remain closed in winter. However, in recent years, the development of roads and tourism has brought change to Ladakh. The beautiful landscape attracts tourists, and the people have begun to develop new occupations in tourism, trade, and services.
The Sahara and Ladakh are both deserts, but they are very different. The Sahara is a hot desert, lying at a low altitude, while Ladakh is a cold desert at a high altitude in the mountains. The Sahara is the largest hot desert in the world, while Ladakh is a high-altitude cold desert.
Despite their differences, both deserts show how humans adapt to extreme environments. In both deserts, the people depend on their animals - the camel in the Sahara and the yak in Ladakh. Both regions are also experiencing change, as oil wealth transforms the Sahara and tourism transforms Ladakh.

The deserts of the world, from the burning sands of the Sahara to the frozen heights of Ladakh, are among the harshest environments on earth. Yet even here, life finds a way. Hardy plants, adapted animals like the camel and the yak, and resourceful people have all learned to survive on the edge of possibility. The Bedouins and Tuaregs move with their camels across the Sahara, while the Buddhists and Muslims of Ladakh tend their yaks and grow their few crops in the short summer. Both deserts are changing - oil has brought wealth to the Sahara, and tourism has opened up Ladakh. The study of deserts teaches us the remarkable ability of human beings to adapt to and live in harmony with their environment.
