Woodfuel is not a new form of fuel; historically wood has been used as fuel for millennia with many civilisations relying on it as a source of energy. Even today the global south still use wood to produce heat. At the turn of the 19th century wood in the UK was no longer the main source of energy, but instead fossil fuel, which now outlines and dominates the way we live today. Furthermore with a growing population since World War II, much of the UK agricultural land has been used for conservation schemes and agricultural harvest only. Nevertheless with the rising concern of climate change, woodlands are now emerging to be used again for the use of renewable energy. Woodfuel in the UK is available as sawdust, pellets, sheets, charcoal chips, and firewood. The particular type used depends upon factors such as application, quality, quantity and source. When we view the geography of woodfuel in the UK we can view it from a broader perspective that reflects the discipline of geography. Sustainability is a way which tries to combine earth landscapes, environments and people together. We view sustainability “through the so called ‘three pillars’, namely economic, social and environmental or ecological” (Gregory et al 2009: 738) and it is these pillars which are to “be used as a benchmark for goals in which we must achieve” (O’ Riordan 2004: 245) so that we can use todays resources without compromising future generations supplies. Due to greater awareness of climate change and the need to use low carbon, renewable source of energy, this essay will predominately focus on the sustainability of woodfuel in the UK.

...roductive agricultural land into biomass production for woodfuel. Even with economic incentives farmers still view this business as a risk to their livelihood. If managed in an appropriate way woodfuel can be rewarding by lowering the UK carbon emissions by 2050 and boost the economy. However to make sure that the woodfuel system is considered sustainable the production system must not impact on local or regional ecosystems, societies and economies. Organisations such as the Forest Stewardship Council and the Forestry Commission can ensure that sustainable practices are in place to manage our woodlands; however this is only one part of the woodfuel system. Both local and regional business and farmers must interact with other to ensure that other systems such as conversion, transportation and waste management are also sustainably managed within the woodfuel system.
The Industrial Revolution was not only a turning point in the progress of human history, but the start of a great change in the Earth’s environment. Technological advances in industry and mass migration into urban areas led to a rising demand for energy sources, a demand met by fossil fuels. Casper, J. (2010) describes coal as ‘symbolic of the beginning of the Industrial Revolution’, the increased combustion of these ‘dirty’ fossil fuels further polluted the air and enhanced the volume of Carbon Dioxide (CO2) in the atmosphere. Changes in land use attributed to population rise, reduced the amount of photosynthesising biomass on Earth, diminished an important ‘carbon sink’ and concluded to enhance the Greenhouse Effect.

“All Biofuels Are Not Created Equal” is a very informative article that everyone should be aware of. The authors of this article show how biofuels can be made to benefit Earth. Our ecological footprint is so big that everyone requires 2.5 Earths to maintain the same lifestyle. What does this reveal? It reveals that Earth’s resources are being diminished. This means that the world needs to do something to prevent this so Earth can last for future generations. The way that biofuels are being made is not very effective in helping this problem. This is because it either requires deforestation or the burning of fossil fuels, which the world is trying to stop. Instead of using corn or sugar cane as ethanol, alternative crops should be used because it will benefit our environment the most.
Taking wood from rainforests and old-growth forests is detrimental to the environment and society. However, it is possible for us to have sustainable wood if we make an effort.
Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).
The gathering of a lot of fuel wood had contributed greatly to deforestation, desertification and other soil erosions. One area that has been decertified is the Sahara desert. Over many years of deforestation and taking of fuel wood, this once a rain forest has become an arid land for heat. When people gather the wood or cut down the tress this leads to soil erosion. The roots from the trees help soil stay in place when there are floods and heavy rain falls. Also trees can help decrease wind speed and not cause sandstorms. In many cases through out Africa, which has low fuel, wood resources there are a lot of sandstorms. The greatly reduce these problems, people should start planting more trees to take the place of all the trees that have been cut down. Trees help us in many ways. With more trees air qualities can be much better. Also by using other resources for fuel can be a good idea to lessen the amount of trees used and cut down.
Global Warming, much of what does or does not happen forty years from now, rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate, there are other environmental problems; “we now face a global crisis in land use and agriculture that could undermine the health, security, and sustainability of our civilization”. Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought-resistant crops. We cannot dispute that automobiles, factories, and power plants, displace an unprecedented twenty tons of carbon monoxide per person per year.
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
Phasing out animal agriculture and replacing it with stronger, safer plant cultivation would greatly reduce pollution released into the environment as animal waste, burning fossil fuels, and contaminated water runoff. The animal waste produced in factory farms is dumped into immense open-air lago...
The 21st century is heavily reliant on burning of fossil fuels, from fueling airplanes, to cars, all the way down to factories. Although the burning of these fuels is helping us advance, it is also harming the planet in ways that no one can imagine. With the planet using over 82.4 million barrels of fossil fuels being used each and every day, there is a need for change, fast. Society must adapt and change in order to successfully preserve the planet, because as of now it is our only home. You might be thinking how one might solve the issue at hand, this is quite simple actually.
Global heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising of sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007). Even though global climate change presents a massive problem there are many proposed solutions to fix or delay it. These theories range from creating a giant sun shield in space to the simple practice of “reduce, reuse, and recycle” (Gray, 2009). However the most effective solution is to find different sources of fuel to power our day to day lives. The earth is in need of renewable, effective, and long lasting fuels. Global warming can be slowed through the use of renewable energy as it is versatile, clean, a good investment, and can easily be put into place in several different climates and environments.
The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).
Through C&I, it is also possible to monitor, assess and report progress on sustainable forest management at regional and national levels. The six Pan-European criteria that best describes the different aspects of sustainable forest management in Europe are listed
More farmers are now planting crops for biofuel, resulting to an intense drop in food production. According to experts this promising alternative energy source is seemingly causing a global decrease of food supply. As the demand for biofuels increases, more industrialized countries are offering encouragements and subsidizing farmers to grow crops for fuel rather than for food. The biofuel production method was also anticipated to be carbon neutral, as the crops would absorb the carbon dioxide released when the biofuel was burned. However crops for fuel are now grown at such a rate that they need more energy to cultivate, grow and harvest. By the time it reaches households, it would have consumed more energy and released more greenhouse causing substances than the feared fossil fuels would have. The fact that emissions are released during production, processing, fertilizer application and as a result of land use change is highly ignored. Somehow biofuels can sidetrack less harmful and clean resources like renewable energies such as solar and wind energy. Large scale cultivation of biofuel crops, unlike small scale, locally produced and biofuel owned farms are commonly challenged by problems such as severe use of water, chemicals, fertilizers and pesticides. These also often lead to pollution, depleting and degrading available water resources which can cause famines. According to contrary believe of analysts, it has also shown that there is not enough farming land on earth to produce biofuel crops to meet the huge energy needs encouraged by our current and unmaintainable ways of living. http://www.greenerideal.com/science/0516-biofuels/ &
