Drought in the Sahel Belt

Extracts from this document...

Introduction

Drought in the Sahel Belt ACTIVITY 5: The Sahel belt is a region in western Africa, forming a transition zone between the arid Sahara on the north and the wetter tropical areas of the south. The Sahel belt runs from Mauritania in the west to Chad in the east. The video which I watched, focused on the Sahel belt in a part of Burkino Faso. A relatively sparse Savanna vegetation of grasses and shrubs predominates. Rainfall averages between 102 and 203mm (4 and 8inches) a year and falls mostly from June to September; periods of low rainfall and drought are common, however. An extended drought in the Sahel, lasting from the late 1960's until the early 1980's the worst in 150 years, suggested and increasingly arid regional climate. ...read more.

Middle

Whereas in January the moist south-westerlie winds do not reach the Sahel belt, as the dry north-easterlie winds are much stronger and therefore converge with the moist south-westerlie winds south of the Sahel. The rains may sometimes fail as well, this is due to the moist south-westerlie winds getting caught over the Ethiopian Highlands, and not reaching the Sahel. The effects of the drought on the Sahel are a lot more disastrous than those we rarely experience in England and Wales. They last a lot longer in the Sahel and they are also much worse, as the areas which are affected are much poorer than those which would be effected in both England and Wales. ...read more.

Conclusion

The Sahel drought was also aggrevated by nonclimatic determiants such as overcropping, as well as by political and milatary conflicts. Human activity has resulted in the drought effects worsening by the increase of children being born, which means more food is required to live up to the demand. The effects of the drought in Africa could be reduced by coppicing, this is where trees are not completely cut down, but only shortened, this would allow branches to continue growing, as there is not enough time to be growing new trees. Dams could also be built to create reservoirs, which would keep any existing water in one place and not from flowing away or infiltrating into the dry soil. Some villages often put rows of stones on the hillsides to improve the farmland, this is called water harvesting. ...read more.

  1. The aim of this project was to investigate what differences exist in temperatures in ...

    However, I have my reservations as to whether this relationship, although positively confirmed by the graph, is actually a true reflection of the relationship between altitude and temperature. One would normally expect that, as the atmosphere becomes thinner at higher altitude, the temperature would be lower.

  2. Peri-glacial areas

    The Loess plateau is yet another prime example of what challenges a peri-glacial environments poses and how we can overcome them. This region experiences the most rapid soil loss in the world, whereby Arctic Winds transport large amounts of loess and deposit this fine, yellow material

  1. Acid rain study

    e) "Acid rain is the creation of human activity." I agree that most forms of acid depositions are man-made from polluters such as road transport and the burning of fossil fuels. These gases are released into the atmosphere and can have horrendous effects of plant, water, fish and buildings.

  2. 'Analyse the measurements of desertification'

    - which again shadows desertification and land degradation. Also the presence of humans and the land-uses that they impose on dryland ecosystems can also encourage desertification. Less economically developed countries (LEDCs) are found within most desert areas across the globe: appendix 1B shows that all but the Great basin desert

  1. WHO IS TO BLAME FOR DESERTIFICATION?

    that one of the most serious cause of desertification in this respect is the fuel-wood crises. The collection of fuel-wood form urban hinterlands in the Sahel, the most severely affected region, has resulted in the almost total loss of trees around major cities.

  2. The Sahel and the ITCZ

    These seasonal shifts have a comparatively minor impact on rainfall patterns in equatorial and desert regions. The mid-Sahara receives little rain, even in summer, because the ITCZ seldom advances that far north.

  1. Geography: Desertification.

    There were antelope, elephants, buffaloes etc." "Villagers used to hunt many wild animals such antelope, monkey, fox, squirrel, rabbit. And even elephant" says Malam Garba, aged 77 from Dali. Malam Garba and his brother harvested 700 baskets of millet from their field 40 years ago which provided a surplus for both their families.

  2. Sahelian Drought Investigation

    Global warming is another cause of drought as it means there are less clouds produced from condensation due to the global temperatures increasing.
