  1. Desertification – Climate Change or Human Influences?

    This leads to several problems that put increased strain on the land. Some of these difficulties include a decline in the fertility of the soil, therefore each time crops are grown they become less successful until they will no longer grow and the land becomes useless, a desert. Also, the topsoil will become crusty by the evaporation of the little rain, which will then increase surface run-off for when it does rain, eroding the soil by gullying. In the 1960s a large-scale development of groundnuts in the Sahel is said to be significantly responsible for the drought of the early 1970s, as thought by Richard Franke and Barbara Chasin (Montclair State College, New Jersey, USA).

  2. Flooding in Bangladesh.

    > Silt, deposited at the mouth of the Ganges and Brahmaputra, has formed a large delta. This eventually created many flat islands. They attracted large numbers of farmers for rice growing. Further deposition of silt blocks the main channels and increases the flood risk by raising the beds of the rivers. Flooding is most likely to occur in late summer following the seasonal monsoon rains. > Water is pushed northwards by tropical cyclones up the Bay of Bengal. Silt deposits cause the Bay of Bengal to become narrower and the sea shallower.

  3. Is the international ban on the trade of ivory consistent with the principles of sustainable development?

    Of the 37 countries that house elephants all have at least 50% of their population living below the poverty line (CIA World Factbook, 2011), which suggests that the ivory ban is not in accordance with sustainable ideals as it curtails the ability of those currently in poverty to meet their own needs. With regard to intragenerational equity, if it is accepted that people must profit from a resource in order to conserve it (Moore, 2011) then it can be argued that there are other methods of commodifying elephants that are far more in line with the ethos of sustainable development than harvesting them for ivory, such as eco tourism.
