The use of Geographical Information Systems can help us measure the state of our forests and ensure that agreed changes are taking place. The information gained can inform decision makers for the conservation of these environments, and alert them to which areas may need protection.
Deforestation and subsequent land-use change are a significant problem. The loss of our tropical forests is resulting in a number of problems including the loss of biological diversity, natural resources, and climate change (through the release of carbon stored).
The continuous monitoring of theses endangered environments is critical for their future protections, and the use of satellite imagery has greatly improved the ease with which this is done. The availability of continuous global data, such as MODIS data (Moderate Resolution Imaging Spectroradiometer) has allowed the systematic monitoring of Earth processes.
Once product available from MODIS is NDVI (Normalised Differential Vegetation Index), and this is been shown in numerous studies to be an accurate measure of vegetation on the ground, and can therefore be used for forest/deforestation studies.
The use of Geographical Information Systems can take these datasets and analyse them to provide analysis across time for the assessment of the state of our forests and the changes that have, and are occurring.
The information gained can inform decision makers for the conservation of these environments, and alert them to which areas may need protection.
