Zusammenfassung |
Rice is produced in more than 95 countries worldwide and is a staple food
for over half of the world's population. Rice is also a major food crop of
Taiwan. There are numerous rice crops planted on the western
plains of Taiwan, and, after the harvest season, the left-over straw is often
burned on-site. The air pollutants from the burning emissions include
CO2, CO, CH4 and other suspended particles, most of these being
the greenhouse gases which cause global climate change. In this study
FORMOSAT-2 satellite images and ground-truth data from 2008 and 2009 are
used to conduct supervised classification and calculate the extent of the
straw burning areas. It was found that 10% of the paddies in the study
area were burned after harvest during this 2-yr period. On this pro rata
basis, we calculated the overall carbon emissions from the burning of the
straw. The findings showed that these few farmers produced up to 34 000 tons
of carbon emissions in 2008, and 40 000 tons in 2009. The study results
indicate that remotely sensed images can be used to efficiently evaluate the
important characteristics for carbon emission detection. It also provides
quantitative results that are relevant to tracking sources of transport
pollution, postharvest burning, and Asian dust in Taiwan. |
