Desertification In Ghana



In Ghana desertification is a strong issue that needs to be coped with. Most of Ghana's land are dry lands considered as deserts. Almost three quarters of Ghana's land are already degraded to some degree. Its seems as if the drought over time is making the situation worse. Crops and vegetables that people in Ghana usually grow has declined for the most part. Most African countries are landlocked and are suffering from poverty. They are really depending on their natural resources. Some people say that 35 percent of Ghana's land is said to be under the threat of desertification. The soil fertilization is on a decline on behalf of desertification. In the Graph above it shows how Ghana and most of Africa has been affected by desertification it shows the Soil Degradation .

Ghana has been suffering from desertification for some time now. Some of the major issues are shown the map above. The red shows the very degraded areas. The orange shows the degraded soil. The tan shows the stable soil and it only shows small areas compared to the others. The gray shows the areas that are being dried out the most and that are suffering without vegetation.
What is being done about desertification in Ghana. A program was made to help the drought in Ghana. This program is helping the poverty issue and the vegetation issue. Its helping pay for seeds to be planted in the stable soil areas. Making so that Ghana's vegetation issue will be on the up rise.

Desertification in Tanzania

          In Tanzania desertification is being found as a big problem. Tanzania is a very under-developed country, and it has been found that the least developed countries need assistance. They need to be getting the assistance from the developed world if they want their country to be okay. Recently in Tanzania; droughts, floods, windstorms, and desertification are more frequent than ever before. Another huge impact is food security is increasingly threatened because of failed harvests.
          Africa is been effected greatly by desertification, and not in a good way. In the image below it shows what areas have been hit by desertification. It's hard to read the key but it says that the darkest areas are now true desert. The middle color areas have an acute risk of desertification, and last the lightest color has a moderate to great risk or desertification. This image is a great way to see how desertification is growing and spreading throughout the continent.



          Some of Tanzania's major environmental issues include: soil degradation; deforestation; desertification; destruction of coral reefs threatens marine habitats; recent droughts affected marginal agriculture; and, wildlife threatened by illegal hunting and trade, especially for ivory. It is susceptible to flooding on the central plateau during the rainy season; and to drought. You can see in the satellite image below that parts of the country are very dry and brown, and lacking any vegetation. This country and other poor countries like Tanzania really need help basically saving their agriculture and land. Desertification only spreads, and it won't go away without a lot of help.
