own massive advances in recent years. Remote sensing in and of itself is obviously not a new idea though, it can be said to have its origins in the use of cameras and balloons in the nineteenth century. The most common remote sensing technology used in forestry is conducted using optical or infrared sensors; and by far the most common method of delivery is the aerial camera. Future technological developments in this field will be in the area of microwave, thermal and ultraviolet portions of the electromagnetic spectrum.
Applications of remote sensing data to sustainable forest development are usually presented in 4 classification areas:-
Forest cover type.
Forest structure.
Change detection.
Forest modelling.
Each of these categories would be further subdivided into separate individual issues. The analysis of the data from remote sensing sources relies upon an understanding of these 4 categories and the role each plays in sustainable forest development.
Context within sustainable development.
It is vital, or course, (as alluded to earlier), that the battle for trees should be seen within the context of wider social, economic, demographic and green issues. If there is a sudden change in world political thinking in the major nations, then planting more trees simply wont be enough. More efficient power generation methods need to be achieved, whether this is through power stations, hydro electric power, wind or solar power. Industry needs to become more efficient in its power usage and we desperately need to address the domestic transportation issue, including greener cars and a reduction in cheap air travel and we need, as individuals, to consume less; particularly in the west were obesity is becoming a very significant issue.
Advice for the future.
It is imperative that the governments of the world, particularly in the west, come to realise the scale of the problem. It is no longer acceptable for leaders like George W. Bush to say that he will do nothing to harm the US economy as an excuse for not implementing the Kyoto protocols. Private citizens also need to become more aware of what they can do to reduce their carbon emissions, and become aware that they can plant trees in order that they become carbon neutral. A massive government investment program need to begin immediately to plant trees and to formulate a genuine sustainable development policy, this would best be done internationally as every country will be affected by global warming. Politicians also need to make difficult decisions; a massive tax on airline fuel would be extremely unpopular with voters, but absolutely necessary in order to reduce the CO2 emissions from air travel, which is set to become the single biggest source or carbon pollution over the next few years. Finally, industry, particularly the automotive industry, needs to put more effort into creating energy efficient products, be they cars, televisions etc. There is no doubt that difficult choices face all of us over the coming decades, avoiding difficult solutions is simply no longer acceptable.
