How can a farmland become desertified?
Farmland can become desertified due to unsustainable agricultural practices such as overgrazing, deforestation, and excessive use of fertilizers and pesticides. These practices can lead to soil erosion, depletion of nutrients, and loss of vegetation cover, ultimately transforming the farmland into a desert-like environment.
How farmland may become desertified?
Farmland may become desertified due to unsustainable agricultural practices such as overgrazing, deforestation, and excessive irrigation depleting soil nutrients and water, leaving the land vulnerable to erosion and degradation. Climate change, such as prolonged droughts or erratic rainfall patterns, can also contribute to desertification by making it harder for vegetation to grow and thrive.
What if the world had no trees How would it be different?
The earth would not be able to support life as we know it, and much of the currently fertile land would become desertified quite quickly through erosion. It would soon end up looking vaguely like Mars (except in more of a yellowish colour).
How are droughts causing desert problems?
Deserts are under a perpetual drought and have no additional adaptation to make. Deserts are patient and can wait out a long term without rainfall and then suddenly spring back to life when the rains do come. Most plants and animals in the desert are adapted to life without an abundance of water. However, areas on the fringes of a desert, such as savannahs, may become desertified and end up enlarging a desert.
What is savannization technique?
The aim of this three-year project has been to create a demonstration station for Israeli and overseas students, scientists, and management personnel. The station shows how ecological understanding of desert landscapes can be applied for reforestation of degraded areas. The project is based on research that shows that biological diversity and productivity in the desert are controlled by factors affecting the flow of water, soil and nutrients. Four sites have been established in Sayeret Shaked Park to show how natural and human activities in the area affect distribution of resources and biological diversity, and to provide evidence of how management activities restore desertified landscapes.
How deforestation and desertification are related each other?
Roots of trees hold the soil particles together so the soil particles are binded together but when deforestation is done in a place no other support is left for the soil particles to be binded so when rain water
How does desertification impact the people in Africa?
Basically there is very little evidence. All too common is the confusion between degredation and desertification. Because Africa's environment is so variable actual desertification can be vary hard to prove due to the seasonal rains and periods of drought. Some areas have actually been classed as desertified but then 3 rainy seasons later have burst back into life. Check out this article: Binns, T. (1990) 'Is Desertification a Myth?', geography 75 (2), pp. 106-113
What are the water problems in the middle east?
There are serious problems and challenges facing the Arab world today. They require immediate attention: 1. Global weather change and its impact on the Middle East and North African regions, such as the decreasing rainfall and the problem of desertification. 2. Insufficient food production in all Arab states. They all rely on food import to meet their basic needs. 3. Shortage of fresh water which caused the Middle East to be among the driest regions in the world. More than 2/3 of Arab countries are classified as water poverty stricken.
How would the temperature on earth be affected if the amount of greenhouse gases in the atmosphere changed?
It would make the greenhouse effect stronger.
What is the dominat religion for hindus?
hey! you gotta know your history well! Let me tell what Africa has contributed to the history of the world. Primarily the first humans originated in Africa, then spread to other parts of the globe gradually, thus Africa is the cradle of humankind. Secondarily the first civilizations even older than that of Egypt, originated in Africa such as nubian-cush and the much older recently discovered zingh empire of north and west Africa before the Sahara was fully dried-up or desertified, the European colonists who much later came to Africa discovered many things among the africans, but didn't want to recognise because they were there to mistreat and degrade anything that was non-European. Even the origin of mathematics is now being traced back to Africa, tropical Africa, in 1950 a belgian researcher named jean de heinzelin De Braucourt discovered a peculiar bone on the Ishango site 15km from the equator on the shore of king edward's river, 10 cm long peculiar bone with a high-level scientifically dating from 20000BC. the bone reveals a mastered arithmetics series, also used to count lunar phases and this is well before the egypto-nubian civilization! There were other great civilizations in Africa, the Great Zimbabwe, Songhai, etc... Central Africa has also greatly contributed to the world in terms of arts, music, everybody knows about African music supremacy. The ancient Greeks who brought civilization to Europe, spoke well of Africa, because they borrowed a lot of their civilization from Egypt. By the way Egypt means "black soil", so does Sudan etc... The desertification of the Sahara has hidden a lot of the African glory. the so-called civilized europeans brought to Africa misery, slavery, political strifes and divisions which did not exist in Africa. Africans had their own cultures,religions,kingdoms,empires,tribes organized in their own way, all this was destroyed by the evils of slavery and colonization which tore people from their roots. despite the turmoil africans wherever they were at, continued to contribute to the world in culture, arts and most of all music which is part of a man soul. Though they were forced and discouraged to progress in many other fields. Even in Roman days, some great Roman soldiers and generals were black, saint Augustus of hippo was black, as well as Simon of cyraene who helped the Christ carry the cross to the place of the skull(GOLGOTHA) was black or quite dark-skinned. The great Nubian pharaoh known as Taharqua was black as midnight, invaded parts of the middle-east well. Many of the pharaohs were quite black too. Moses, Solomon of the bible days had black wives. Did you know the ancient empires of Zingh,Egypt had a technology quite different from ours but well advanced in sciences such as astronomy. So if you wanna know what Africa has contributed to the world history, search! In America, Africans or blacks what you call them there, have been seen as inferior, because of that evil history of slavery, that created a powerful stereotype. Africans were not always slaves,others were kings or just simple folks. Actually for the ignorant ones, the Kingdom of Portugal in the 15th century had a perfect diplomatic ties with a central African kingdom called the Kongo, the Kongo noble children went to portuguese royal court often even learn to speak portuguese. I, myself am a descendant of an African royal line on my paternal side, but was disrupted by evil colonization. Even democracy existed in Africa as well, in my tribe, the luba, people were ruled by a council of elders representing various clans rather than by a king who acted as a judge. So Africa did contribute greatly to history of the world. I hope this answer will enlighten many people who have no clue about Africa except for the pictures of warn torn areas with starving chilren!
