Global warming‚ and how much of it can be put down to natural causes. Nonetheless‚ there are clear pieces of evidence provided that suggests global warming is down to anthropogenic causes‚ and that of economic activity. Firstly‚ the mass amount of deforestation that takes place across the world today can have drastic effects on global temperatures. For example‚ vegetation works in harmony with human life as they help to keep the balance of carbon dioxide in the atmosphere by absorbing it‚ with the growing

has caused conflict in the 7 states the river cater too. Urbanisation in the river basin in Bangladesh‚ one of the poorest countries in the world‚ has increased the flood risk enormously and has meant that the local people have to learn to diversify their livelihoods in order to survive. One of the major needs for management in areas with river basins is to reduce the flood risk‚ especially in LICs such as Bangladesh where urbanisation and global warming has increased the flood risk exponentially

Isles can be found in the Northern Hemisphere where deciduous forest is the main biome. Here physical and human factors have accounted for changes to the vegetation for many years. Human factors can include tourism‚ agriculture‚ urbanisation‚ interception and deforestation. Physical factors can be such things as natural disasters‚ succession and diseases. The human factor of interception can vary between many situations. For example‚ humans can intercept and alter the vegetation through predator

Population growth was found as main cause of deforestation which is a land use change practiced worldwide. Meyer and Turner (1992) asserted that population growth

droughts. These problems have been compounded by decades of unregulated deforestation‚ which has had a telling effect on the country’s forestry resources. In 1947‚ at the time of independence‚ nearly 25 per cent of Pakistan was covered by forest. Today‚ due to the rapid increase in unplanned urbanisation and agriculture‚ only around five per cent of Pakistan is forest-clad. The consequences of such rapid deforestation have serious environmental implications‚ leading to soil erosion‚ rising

The tradition concept of development has for a considerable period of time been driven by economic considerations. Exploitation of natural resources which leads to environmental degradation motivated by targets of maximum profits has been the norm and little regard has been granted to the side effects of development initiatives. Gradual escalation of awareness and realisation of the range as well as the magnitude of environmental effects of development initiatives led to worldwide discussions on

In Bangladesh‚ mass deforestation occurred to populate the increasing number of people. This means less interception from vegetation‚ increasing the amount of water entering the rivers. In contrast to this‚ urbanisation of Boscastle increased the likelihood of flooding. Before the flooding occurred‚ they were allowed to develop on a narrow flood plain where rainfall was
