One of the most challenging global issue facing today’s society is climate change, it is affecting all regions across the globe, with some areas experiencing extreme weather events and heavy rainfall, whereas other regions are hit with droughts and heat waves. Climate change can be defined as a “large-scale, long-term shift in the planet's weather patterns or average temperatures.” (metoffice). Consequently, a range of challenges are occurring to not only human settlements, but more importantly to
From 2000 until 2030 the urbanized areas will be nearly tripled1 because of the demographic transition from rural to urban. The use of dark building materials, such as asphalt and concrete, leads to a lower albedo in urbanized areas than in natural environment2, fostering local and global warming. In turn, the increase in urban albedo might support climate stabilization efforts3. Here, we investigate the potential effect of the increase in albedo in a representative set of European cities relying
mostly urban planet. In 2030 the urbanized areas will be nearly tripled compared to 2000 (Seto et al. 2012). The use of dark building materials, such as asphalt and concrete, leads to a lower albedo in urbanized areas than in natural environment. Lower albedo increases ambient and global temperature. Inversely, the substitution of rooftops’ membranes and pavements’ traditional materials with bright ones and a wise planning of future urban development can increase albedo and support climate stabilization
warming but also the Urban Heat Island (UHI) effect. Apart from causing the rise of temperature in urban areas, UHI effect also induces some undesirable impacts to Hong Kong citizens who are living in the urban areas. We shall never underestimate the potential dangers caused by the UHI effect and we should treat it more seriously. This paper will give a brief introduction on UHI effect, its influence and the possible measures that can deal with it. Urban Heat Island (UHI) effect describes predominately

decline in rural population. The effects of Urbanisation can be both positive and negative, whether it is on the peoples, the society or the environment. The practice of urbanisation has brought with it, many arguments as to whether it is a positive or negative phenomena. Throughout the course of this discussion we will look deeper in to what urbanisation really is. We will also analyse the arguments, and we will begin to unpack how urbanisation positively effects the environment as well
There is no doubt that climate change is happening around the world. Climate change is occurring everywhere, but not everyone can see it. Some people fail to realize that climate change is happening because they aren’t aware of what it is. According to the Oxford Dictionary, it is “the change in global climate patterns are attributed largely to the increased levels of atmospheric carbon dioxide.” Carbon dioxide is accumulating in the air, which captures the sun’s heat. In return, the earth is
Economic states of Bangladesh are very typical to any of the most Penetrable countries to Natural Disasters in the world . The total land area is 147,570 sq. km. consists mostly of Floodplains (almost 80%) leaving major part of the country (with the exception of the north-western highlands) prone to flooding in the rainy season. Moreover, the adverse affects of Climate Change – especially High Temperature, Cyclones and Sea-level Rise, Storm Surges, Salinity Intrusion, Heavy Monsoon Downpours etc. has aggravated
At a meeting of the Mayors' Task Force on Climate Change, Disaster Risk and the Urban Poor in April 2010 in Copenhagen, participating mayors and the World Bank agreed to undertake case studies in four cities – Dar es Salaam, Jakarta, Mexico City and São Paulo. The main aim of these case studies was to take stock and learn from what is happening with regard to urban poverty, climate change and disaster risk management in these cities. The key findings from this report are summarised below: • Strong
The term ‘urban heat island’ refers to the localized increase in temperature associated with an urban area. The UHI is an example of unintentional climate modification when urbanization changes the characteristics of the earth’s surface and atmosphere. It was observed that the UHI effect might result in minimum urban temperatures being 5-6° greater than the surrounding countryside. In the case of London, mean annual temperature was 11°C, while the surrounding countryside was 9.6°C and the suburbs
