Although the environmental benefit seems clear, this harvesting practice’s social implications are yet unknown. This study assessed social performances of green and burnt manual sugarcane harvesting in North-Eastern Thailand, the region hosting the largest sugarcane plantation area, using the Social Life Cycle Assessment technique. Data collection was undertaken by surveys. The performance reference points method was applied to assess the different stakeholder’s social performances. Key stakeholder groups examined were workers, local community, and farm owners. The main social issues included in this study are fair wages, working conditions, health and safety, local employment, economic development, social responsibility, and satisfaction of occupation. The results showed that the social per...

In one of them, the human demand for water explicitly includes environmental water as one of the components (WSIe1), whereas in the other, environmental water is explicitly reserved by subtracting it from the water availability (WSIe2). The results obtained from using the two approaches in the case of Bang Pakong watershed correspondingly contribute to the explanation of the existing stress situation, especially in the dry season. The stressful results were noticed during December to February for both approaches as a result of less available water and higher environmental water requirement. The assessment of environmental water requirement (EWR) in this study was quantified according to low and high flow periods. The two approaches perform well for assessing water scarcity in the Bang Pakong watershed; however, the result int...
