� Expected benefits and overall length of time for expected benefits from gully works; � Up-front costs, on-going maintenance payments( if required) or other public costs required to maintain benefits; and � A discount rate if the incentive is staged over time.
Calculators are not a new concept- QDAF is currently developing calculators to estimate the cost: benefit of grant-funded water quality projects in the cane, grains, banana and grazing industries. A similar riparian benefit: cost calculator( simple spreadsheet with user manual) has been developed and used successfully in Victoria). A gully calculator would codify emerging knowledge about the costs and benefits of gully remediation projects, which would improve the effectiveness of grants for gully remediation, and any future incentive systems such as reef credits.
4.2 Recommendations for the LDC project for the management of large gullies and the improvement of ongoing land management
4.2.1 Recommendation 2: Consolidate and improve data about land and landholders
As discussed in previous sections of this report, there is great heterogeneity of landholder types, motivations, capacity to change and history of engagement, as well as land condition, management practices and presence of gullies( that may be a legacy of previous land condition and practices). A greater understanding of the BBB enterprises, including social and economic characteristics, would enable LDC to better target incentives. This more nuanced understanding of how landholders engage with incentives offers a learning opportunity that could have significant legacy value to water quality programs across the GBR grazing lands. It is recommended that the LDC consolidate their understanding of BBB grazing enterprises by collecting, collating and using spatial data and information about:
� Current land condition and land management practices; � Presence and characterisation of gullies; � Social and economic characteristics of landholders and enterprises; and � History of engagement with extension services or water quality programs.
4.2.2 Recommendation 3: Implement a suite of complementary incentives to support landholders in ongoing land management for water quality benefits.
It is recommended that the LDC project should provide a complementary mix of incentives to engage and support BBB graziers to improve water quality across the spectrum of land management practices as per
Figure 6. It is recommended that, in addition to existing regulation, the LDC offers a complementary mix of incentives including:
� Working positively with existing and proposed regulations; � Providing ongoing access to information( such as property management planning, financial planning etc); � Providing ongoing assistance to engage with and / or achieve BMP accreditation;
