Abstract
As population and consumption grow, so does crop production and its residue. Crop residue is traditionally burned in developing countries, which impacts environment, economy, society and health. Thailand faces similar challenges as it is among the largest producers of rice paddy and sugarcane in the world with 83% of its total burnt residue coming from these crops. To address this problem, the Government of Thailand has implemented some policies (e.g. Alternative Energy Development Plan (AEDP) and zero burning policy for sugarcane) targeting both, the use of residue, and the practice of burning. While these policies appear to control residue burning to some extent, there are still challenges, especially for poorer farmers, who rely on manual harvesting practices. The paper looks into the current status of rice and sugarcane residue burning, its impacts on the environment, existing policies, current challenges, and future solutions through sustainable management practices. To achieve reduction in residue burning, the best possible solution is to use residue for alternative purposes. Some sustainable management practices include use of residue for energy production, green harvesting to improve soil nutrients, biochar production and composting. Thailand can also learn from solutions implemented in other countries, to reduce some of the impacts of crop residue burning.
