Energy demand is placing increasing pressure on the economy and the environment. Global economic growth has caused irreversible damage to the environment along with the risk of not being able to meet the future energy demand. The conservation of energy in Ireland and around the world is therefore of extreme importance. There are numerous reasons why energy is important in businesses and in the home. Energy costs are one of the main worries for businesses and therefore reducing these costs would...
This report provides an insight into the current and future situation of the energy sources for powering vehicles in Chile. The country could benefit if special emphasis were put on alternative transport fuels. The analysis of these fuels is structured as follows: the first section discusses issues related to natural gas, followed by biofuels and lastly technological changes to the traditional powered vehicles. Fossil fuels are responsible for 60% of the total energy generated in Chile and only...
Excessive exploitation of ground water led to sea water intrusion in coastal areas all over the world. This is undesirable as this water is unpotable and unsuitable for agricultural and industrial uses. This paper deals with various possible causes and ill effects of sea water intrusion in coastal areas. Also the hydrology of the sea water intrusion phenomenon is discussed. Finally various methods of controlling or reducing the sea water intrusion are presented. Water is vital to life. With...
Climate change is affecting the planet including coastal and ocean environments in a number of ways. The impacts are not only related to increasing temperatures but also due to for example decrease in PH, sea level rise and altered patterns of and intensity of winds and storms.These phenomena have impacts on the ecosystem and a number of economic activities including the maritime industry. The Oceans cover almost 72% of the earth surface and provides a great and varied living space for...
In conclusion, taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world .Taxonomic knowledge is a key input in the management of all types of ecosystems. We need taxonomy because there are many more species that remain unidentified in Malaysia thus we need to use taxonomy to catch up the pace that we have lose far behind. Taxonomy is consider as a sciences because it involve the discipline of scientific method which...
Introduction Strategic spatial planning is arguably an approach which rails against the discourse of the scientific rational comprehensive models of planning which has and still does hold a large influence in current modes of planning. This short essay will hopefully explain to planners why a strategic spatial planning approach is more conducive in the current context which we find ourselves in. This will be done through answering a set of questions which will clarify the approach, its purpose...
This palaeo-environmental reconstruction is based upon using a multi-proxy approach to analyse lake sediments. The lake of Wuxu-hai lies in the Province of Yunnan, southwest China (figures 1 and 2) and consists of a single basin measuring 1.7km2 situated at an altitude of 3630m a.s.l. It is thought that Wuxu-hai Lake was formed by glacial processes during the Last Glacial Maximum (LGM). At present, the catchment lies in a sub-alpine vegetation belt situated at 250m below the current treeline....
There is ample evidence to demonstrate that Carbon Dioxide (CO2) is the main driver of climate change and Greenhouse Gases (GHGs) contribute to radiative forcing and the enhanced greenhouse effect; due to man-made emissions, mostly CO2, the earth presently has an energy imbalance which contributes additional warming of the surface (Meunier, 2007). This makes reducing and controlling the levels of atmospheric CO2 by enhancing sinks and reducing sources a growing concern, particularly as...
1. Introduction Nowadays, a constant growth of carbon emissions into the atmosphere has been observed, possibly leading to earth's climate change. Transportation contributes to the aforementioned phenomenon through emissions of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HCs) and other types of pollutants occurring from the combustion of fossil fuels. In this paper modes of sea and air transport will be compared in regards with their energy use and carbon emissions. Moreover, some...
World Food Day, 16 October, highlights the need to ensure that all people have physical and economic access at all times to enough nutritious, safe food to lead healthy and active lives. More than half the world's population lives in low-income, food-deficit countries that are unable to produce or import enough food to feed their people. More than one-third of all children are malnourished and 6 million children a year die of causes related to malnutrition. Most of the world's hungry people are...
