Rice is a widely grown crop in Asia. China (30%) and India (21%) contribute to about half of the world's total rice production. In this study, three major rice-producing countries in Asia are considered, India, Thailand and the Philippines (the later two contributing 4% and 2% of the world's rice production). Rice straw is one of the main field based residues produced along with this commodity and its applications vary widely in the region. Although rice production practises vary from one country to another, open burning of straw is a common practice in these countries. In this study, an approach was followed aiming at (a) determining the quantity of rice straw being subject to open field burning in those countries, (b) congregating pollutant specific emissions factors for rice straw burning, and (c) quantifying the resulting air pollutant emissions. Uncertainties in the results obtained as compared to a global approach are also discussed.
水稻是亚洲广泛种植的作物。中国（30%）和印度（21%）的水稻产量约占世界水稻总产量的一半。本研究考虑了亚洲三个主要水稻生产国，即印度、泰国和菲律宾（后两者的水稻产量分别占世界水稻产量的4%和2%）。稻草是与这种农产品一起产生的主要田间残留物之一，其在该地区的应用差异很大。尽管各国的水稻生产方式各不相同，但露天焚烧稻草在这些国家却是常见的做法。在本研究中，采用了一种方法，旨在（a）确定这些国家露天焚烧的稻草数量，（b）汇总稻草焚烧的污染物特定排放因子，以及（c）量化由此产生的空气污染物排放。还讨论了与全球方法相比所得结果的不确定性。
