Greetings And Salam Sejahtera!
It’s less than 3 days before COP21.
Three of our colleagues are attending the 11th Conference of Youth (COY11) in Japan
while 6 of our Malaysian Young Delegates are already taking their positions in Paris
for the grand meeting.
Here’s Jolene with her cheerful countdown post =)
Let’s read up about LULUCF to enrich our knowledge on climate change =)
Land use, Land Use Change and Forest (LULUCF) is one of the important climate mitigation actions. It is defined by United Nations Framework Convention of Climate Change (UNFCCC) as “A greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use, land use change and forestry activities”.
Land is divided into managed land and unmanaged land. Land is considered managed if it has been affected by direct human intervene whereas unmanaged for all other lands which is largely inaccessible by human. With the increase in human population and development, the demand of land is getting higher. We are converting land faster than the ecosystem can recover by itself. Most lands are converted into human settlements, agricultural and industry.
LULUCF is responsible for the source and sink of greenhouse gases in the atmosphere. Forest helps to remove GHG and it is a cost effective ways to combat climate change. However, GHG will be released if the sink damaged and act as a source of GHG instead. Scientist reported Amazon forest losing carbon-storing ability as the increasing high temperature has caused death of millions of trees than growth. “Tree mortality rates have increased by more than a third since the mid-1980, and this is affecting the Amazon’s capacity to store carbon” said Roel Brienen of the University of Leeds. Furthermore, 40% of the land today has converted to agricultural land to meet the food demand. We are developing lands in an unsustainable way and caused irreversible damage to ecosystem such as habitat loss, extinction of terrestrial species, altered land surface and release of carbon soil. From research study estimated that CO2 emission from land use change and forestry is 10-15% of total human induced emission.
Many countries are adopting good management practices in LULUCF but it is difficult to estimate GHS removals and emissions. In order to obtain accurate information, the data collected must be adequate, consistent, complete and transparent. With the emergence of technology, remote sensing techniques have been introduced to obtain map of land use of all areas in a country. This can be done through sensors on board satellites or by camera equipped with optical or infrared films which installed in aircraft. The collected data help to estimate the land area and cover, follow by ground survey data to ensure accuracy in image classification. Among the most important types of Remote Sensing data are aerial photographs, satellite imagery using visible and/or near-infrared bands, and satellite or airborne radar imagery.
We are uncertain about how much carbon can be restored from LULUCF in future, depending on the commitment given by world leaders who manage to walk the talks and also influence from climate change. I believe sustainable management of LULUCF is a way forward to conserve the carbon stock for present without compromising the needs for future.
