Cost-benefit analysis, sustainability

The simulations revealed that the sustainability of a control program mainly depends on the duration of application of a particular control scheme (Figure 8.5). Thus, a minimum number of years is needed to eradicate the disease. Obviously, the higher the frequency of baiting, the faster eradication can be achieved, but a higher frequency is also more expensive. A detailed cost-benefit analysis of different control schemes is included in Hansen et al. (2001, 2003). The strategy applied in the field trial, which was based on the conceptual model described earlier, never was sustainable, no matter how long it was run. 

A wide range of sustainability-assessment methods have been developed in recent years. Some well-known and commonly used tools for sustainability assessment are Criteria and Indicators (C I), Life-Cycle Assessment (LCA), Environmental Impact Assessment (EIA), and Cost—Benefit Analysis (CB A) (Buytaert et al., 2011). This section focuses on LCA, aiming to present its basic stages.
