河湖健康评估-澳大利亚累达令盆地水管理计划概述

Commonwealth Water Act 2007



Provides for integrated management of water resources Enable Commonwealth in conjunction with States to manage Basin’s water resources Optimise economic, social and environmental outcomes
Concluding Remarks




Water is a scarce, finite, valuable resource Strong governance and clear decision making are important but difficult The best decisions are underpinned by best available knowledge and information including R&D Aim for transparency of and ‘whole of basin’ collaborative approaches to planning and management processes Pursue active stakeholder involvement and understanding

Identify Key Environmental Assets (KEA)
Based on Five Criteria: 1. Recognised significance; 2. Natural, near natural, rare, unique; 3. Critical habitat (drought refuges, breeding sites); 4. Threatened species; 5. Sites of high biodiversity (total 2,442 KEA across MDB) Key large representative floodplains, wetlands – total 18 hydrologic indicator sites for 18 IA (a subset of 2,442 KEA across MDB) Location, flow, duration, frequency, spells, intervals – sets environmental demands in hydrologic models Focus on ‘in-channel’ functions and processes (total 88 hydrologic indicator sites for KEF across MDB) Flow indicators examined as indication of KEF – sets environmental demands in hydrologic models
The Murray Darling Basin
Water management challenges

Overallocation Groundwater use impact on surface water systems Serious environmental degradation; reduced environmental flows & water quality Loss of productivity & economic activity Risks to community water supply Severe & prolonged drought & conversely floods Significant water related impacts due to climate change Large and naturally variable basin Multiple jurisdictions
Murray-Darling Basin Authority (MDBA)
• Role/Functions
• • • • • Preparing the Basin Plan for Commonwealth Minister’s approval Accreditation of state water resource plans Measure, monitor and enforce compliance on water resources Engaging the community Some water system operations and natural resources management

What does the Basin Plan Mean for Water Planning in Queensland?
The Basin Plan binds - Basin State Agencies - Infrastructure operators - Holders of water access entitlements (industry)
Water Planning - Qld will continue to plan, allocate and manage water resources within its borders but… - Qld Water Resource Plans for MDB catchments will need to be accredited by the Commonwealth Minister responsible for water (with advice to be provided by the MDBA) - Must comply with the Basin Plan
Commonwealth Environmental Water Holder (CEWH)

Manages the water entitlements purchased by the Commonwealth for the environment Water purchased through the Water For the Future Program should reduce the impact of new limits on diversions set by the basin plan on existing water users

Concluding Remarks (cont’d)



Test for consistency and coherence of policy (e.g. institutional, entitlement, pricing, planning) Remember principles of Ecologically Sustainable Development and Triple Bottom Line Include adaptive management including requirements for monitoring, reviewing and reporting Consider linking reform milestones with incentives and sanctions
