Many people already used up all these fuel wood resources through out these years and now there is not enough for people to use. The gathering of a lot of fuel wood had contributed greatly to deforestation, desertification and other soil erosions. One area that has been decertified is the Sahara desert. Over many years of deforestation and taking of fuel wood, this once a rain forest has become an arid land for heat. When people gather the wood or cut down the tress this leads to soil erosion.
Some of these areas include surrounding parts of the Sahara Desert in Africa has well as much of China. The causes for desertification are the same throughout the world but may be more damaging in these areas. These causes include intensive agriculture, overgrazing of animals and lack of water resources. In agriculture, “row crops […] leave soil exposed for... ... middle of paper ... ...e should not consider it a local problem. To reiterate, this area has suffered from drought for much of the past decade.
Agricultural Problems facing the African Nations Africa is a nation hit by many agricultural problems. As a majority, Africa is a desert type climate. Rainfall is heavy and quick, leaving soil deeply engraved by the pounding of the rain. It falls for such a short period of time, not allowing the ground to soak up the moisture before it is evaporated into the air because of the heat. Droughts attack the nations often never providing enough food to sustain the rising population of the nations.
In addition, wells are drying up. In some areas wells are the only source of water. Pastoralists across the continent are losing cattle, with nothing to provide for them, due to the arid conditions. Along with the wells, natural springs are disappearing. Sand erosion is also causing wells to vanish.
The fertile landscape dried up and the desert widened, creating the form that appears today. As conditions gradually became drier, however, and desertification set in, farmers abandoned their land and the animals migrated to other areas. The Sahara’s climate is very hot and dry. Although it is very hot during the day, it does become cold at night. On average, it only has 8 inches of rainfall per year.
There are different types of deserts. What makes a desert a desert? Deserts are deserts because they lack water. It rains so rarely in a desert that some deserts even go two years without a drop of rain. The soil is so dry and hot that sometimes when rain comes, the rain evaporates before it reaches the ground.
During the Great Depression, or the “dirty thirties”, the land had changed and definitely not for the better seeing that “severe drought and high winds degraded [the] farmland” (Gale, 2008). Although it was not nature’s fault for the Dust Bowl; the “years of overproduction and poor farming techniques had stripped the land of protective topsoil and left it vulnerable” to all patterns of western weather (Gale, 2008). These conditions did not come swiftly and technically started during the 1800’s, when pioneers first started to settle there. Their “cattle overgrazed the land, stripping it of the shrubby grasses that had held the soil in place for centuries” and they “used growing methods common to the more humid eastern United States” because that’s all the pioneers knew about farming (Gale,
Poor agricultural practices and years of drought caused the Dust Bowl, planting the same crop on the same area of land year after year caused the topsoil to become dusty, wind storms eroded the soil lifting dust into the air, thus creating the Dust Bowl ("The Dust Bowl” & “The Era of Arid Air"). By growing the same crop on the same land the soil became depleted in nutrients creating a dusty top layer. Despite their best efforts, farmers were unable to grow crops for there was no topsoil and no water because of the drought. Unable to grow crops, consequently many farmers could not afford to pay rent and without an income a “...quarter of the farmers fled the area, ...toward California, where they believed they would find plentiful work and better conditions.” ("The Dust Bowl” &” The Era of Arid Air"). This meant that a quarter of the farmers who supplied food for the U.S. fled the area resulting in a lack of food, therefore affecting the economy as well as those who depended on the food supplied by these farmers.
Even so, life in Egypt hadits risks. When the Nile? flood waters were just a few feet lower than normal, the amount of fresh silt and water for crops was greatly reduced. Thousands of people starved. When flood waters were a few feet higher than usual, the unwanted water destroyed houses, granaries, and the precious seeds that farmers needed for planting.The vast and forbidding deserts on either side of the Nile acted as natural barriers between Egypt and other lands.
There was already very little water, so the cattle started dying off by the thousands. Country that used to look like an ocean of grass turned into a dried out, wind blasted desert. During this same time, the railroads were being put in across the country and cattle were starting to be shipped on trains. (This meant higher transportation costs when cattle prices were starting to go down.) Some of the worst parts of Arizona's history was caused by the Hashknife Outfit and its cutthroat hired help.
