The fuel wood crises, is the consumption of wood more than the amount of trees that are growing back. In the 1970’s there was much talk about an rising amounts of fuel being used due to the rising amount of poor people, and that the way they are dependant entirely on wood for cooking and heating, would devastate forests result in deforestation. Certain agencies and governments decided to save the amount of trees. They often failed, because farmers showed little interest in planting low-value wood crops. Afterwards, it seemed that the predictions were wrong, because fuel wood consumption and the excessive use of wood, died down and less research was done about it. Approximately 2.4 billion people currently use wood and other forms of biomass for cooking and heating. However, global consumption of fuel wood apparently peaked in the mid-1990’s and is now begging to decline. The demand for fuel wood is leading deforestation in a limited number of areas that concentrated on producing fuel wood and charcoal, particularly in Africa, but in most places it has not gone to significant deforestation. Indeed, most of the fuel wood used today comes not from forests , but form scrub, bush fallow and the pruning of farmland trees. And much of the fuel wood which does come from forests is coming from forests being cleared for agriculture. In urban areas, wood tends to be the fuel of necessity rather than choice. As people become wealthier they shift to fossil fuels such as kerosene and electricity, although in many African cities charcoal has become the main substitute for wood. Where this is happening, demand for charcoal has been growing extremely. One of the reasons why many of the 1970’s predictions were wrong is because researchers failed to expect how quickly fuel wood would be replaced by other fuels. The consumption of fuel wood is declining over much of Asia, and almost the same in Latin America, but in Africa it continues to rise. The pressure comes not so much from rural dwellers, as it does from rapid population growth in the cities, compounded by poverty. In 2000 an estimated 583 million people in Africa relied on fuel wood, charcoal and other biomass for cooking and heating. By 2030, the number will have risen to some 820 million people. Even though the man problems seem to die down, the fuel wood crisis still continues and nobody knows when it will strike up again. It can be regarded as a sleeping giant that only we can awaken or permanently put to rest. With that view in mind, it may be better to find alternatives as opposed to causing such catastrophic results and a lack of the medium. Renewable Energy Sources are still the best manner to obtain energy, and are the best way to step into the future.
The world’s forests are being destroyed at unprecedented rates. The major threats to forest genetic resources are atmospheric pollution and deforestation. A big threat is the narrowing of the genetic base of tree species as a result of commercial forest operations. More then 400 temperate and tropical species of trees were endangered in whole or in significant parts of their gene pools in 1985. One of the causes of genetic erosion of forest tree species is the breeding of a few economically important species in the absence of conversation programs.
The cause of tropical deforestation varies from region to region. The main activities associated with deforestation are as follows; the permanent conversion of forest land to agricultural use; harvesting of fuel wood and charcoal; commercial logging; dams; oil and mining projects; shifting cultivation; expansion of urban and industrial areas; overgrazing and fodder collection.
The loss of forest genetic resources is not confined to the tropics. Temperate and boreal forests count for almost half of global forest cover, but because they contain less biological diversity than tropical forests, they usually receive less attention. This means that they in fact have to suffer more due to the fact that they do not have many trees. Temperate and boreal forests may be stable, but they are still disappearing. They are in some cases being destroyed at a higher rate then that of deforestation in many countries. With the endless decline in trees, global warming will start to come up a lot quicker.
The effects of global warming could be disastrous for forests, especially those in higher altitudes. According to the WWF International, even a 10C of temperature would lead 25% of the world’s boreal forests being wiped out.
Scientists predict that higher temperatures and drought caused by global warming will trigger forest fires and invasions of pests and diseases, thus accelerating the loss of forest biodiversity.
Fuel wood crisis is the use of wood more than the amount of wood that is being made, so it will eventually result in deforestation, a problem that will speed up global warming. Although the fuel wood crisis may seem uncontrollable, there are a number of ways in which you can stop the fuel wood crisis or at least bring the numbers down. A few of them are: making fuel wood consumptions. This involves making of what is almost like a farm where trees are grown to make sure that there is always enough wood, so there is little chance of there being a fuel wood crisis. However, charcoal is becoming popular instead of using wood as it retains heat longer, which is good for the fuel wood crisis. But coal is not a very healthy thing for the environment, due to the fact that when it is burnt carbon dioxide is released into atmosphere, resulting in an excess of the greenhouse effect, which therefore results in an increase the rate of global warming. There are many more solutions in stopping the fuel wood crisis, and they each have their own pros and cons, but some have more pros then cons.
