Sector-wise midpoint characterization factors for impact assessment of regional consumptive and degradative water use.

摘要: Water availability, resulting from either a lack of water or poor quality is key factor contributing to regional stress. This study proposes set sector-wise characterization factors (CFs), namely consumptive and degradative stresses, assess the impact withdrawals with life cycle assessment approach. These CFs consider quality, competition for between domestic, agricultural industrial sectors ecosystem at watershed level. were applied case management in Taiwan show that both seasonal decrease availability contributes high stress, whereas scarcity due degraded not meeting sector standards has little influence on increased Degradative stress was observed more than sector, which implies agriculture may have concerns. Reducing intensity alleviating scale stresses watersheds are suggested as approaches use. The results this enable detailed analysis resource policies.
