River Murray and Lower Lakes catchment risk assessment for water quality: Results and management options 3.5 Options for management of risks, BB & LB LAP areas Several current and future potential options to manage risks identified in the BB & LB LAP areas are shown in Table 3.7 in the categories of: capital and on-ground works, capacity building, monitoring, compliance, policy planning, and research and development. The suggestions as to which stakeholders may take responsibility for undertaking management options do not imply that they should, or will, be performed by those parties. Management options and stakeholder responsibilities will be examined in much more detail in Stage III of this project, following further consultation and more in-depth examination of priority risks. Funding would be required for some strategies and funding sources are yet to be determined. Uncertainties in risk assessment rankings may also need to be addressed before management decisions can be made. 78
