“…Yet the size of the non-use values for protecting the GBR, as identified by Rolfe and Windle (2012a,b) and Deloitte Access Economics (2017), confirm that protection of the GBR is largely a public good. Given that Australia is a developed country, public funding can only be expected to be allocated from within the country, where the ongoing challenges are to improve the efficiency in the way that it is prioritised and allocated (Star et al 2018).…”

“…The Australian and Queensland Governments have developed a number of plans to improve protection of the GBR, together with significant public investment over multiple programs to help achieve targets (DEHP, 2016). As more evidence becomes available about what benefits can be achieved in different programs it has become possible to identify the extent to which existing investments have been cost-effective , and what should be the priorities for further investment (Star et al, 2018). Allied with this has been growing interest in innovative forms of financing, partly to help augment commitments of public funds with private capital 2 .…”

“…Beher et al (2016) and Rolfe et al (2018) have identified that these grant programs are not very efficient, recommending that better ways to prioritise and allocate funding be identified. The use of water quality tenders and other auction mechanisms to allocate public funds are one approach to improving cost effectiveness (Rolfe and Windle, 2011b), as are efforts to prioritise where public funds are best invested (Star et al, 2018).…”

The Great Barrier Reef (GBR) is a World-known, iconic environmental asset whose complex functioning is largely ascribed to its outstanding biodiversity, ranging from genes to plants, animals and entire ecosystems. Biodiversity has been key to its resilience over the past millennia. However, the combined effects of climate change, water quality degradation and coastal development are threatening the GBR's resilience. There is a crucial need to better understand the value of biodiversity in that region to encourage sustainable policy-making.Different approaches have been suggested in the literature to value biodiversity. First, we review the use of a Total Economic Value framework to look into all dimensions of biodiversity values. Second, we describe an approach relying on ecosystem services. The suitability of these two approaches to value biodiversity in the GBR is assessed. Next, we review 23 finance mechanisms and discuss the possibility to use them to alleviate pressures on ecosystems and biodiversity in the GBR. We conclude by stressing the importance of biodiversity valuation in the GBR, highlight some of the remaining challenges and provide recommendations for future research avenues.

“…A large body of research focuses on agricultural impacts on the Great Barrier Reef, where some watersheds are covered by ∼95% agriculture (Fabricius et al, 2005;Hunter and Walton, 2008;Drewry et al, 2009;Bartley et al, 2014;Star et al, 2018). Studies across 35 river basins show that higherrainfall basins with intensive cropland (sugar cane, bananas, and horticulture) are primarily responsible for dissolved nutrient and pesticide/herbicide runoff into the Great Barrier Reef, while drier savanna/woodland catchments with heavy grazing contribute the majority of sediment and particulate nutrients, though sources vary by watershed (Lewis et al, 2009;Kroon et al, 2012;Waterhouse et al, 2012;Thorburn and Wilkinson, 2013;Bainbridge et al, 2018).…”

Land Use Impacts on Coral Reef Health: A Ridge-to-Reef Perspective

Over 60% of the world's reefs experience damage from local activities such as overfishing, coastal development, and watershed pollution. Land-based sources of pollution are a critical threat to coral reefs, and understanding "ridge-to-reef" changes is urgently needed to improve management and coral survival in the Anthropocene. We review existing literature on spatial-ecological connections between land use and coral health, specifically examining vegetative, agricultural, urban, and other land-use types. In general, forested land use is positively related to metrics of coral condition, while anthropogenic land uses like urban development and agriculture drive a decline in coral cover, diversity, colony size, and structural complexity. However, land-use and land-cover impacts vary across time and space, and small portions of the landscape (e.g., discrete segments of unpaved roads, grazed and scalded hillsides) may have an outsized effect on reef pollution, presenting opportunities for targeted conservation. Some coral species show resilience under land-use and land-cover change, and the impact of land use on coral recovery from bleaching remains an active area of research. Finally, a spatial bibliography of existing literature reveals that most ridge-to-reef studies focus on a handful of regional hotspots, surface water, and watershed-scale dynamics; more research is needed to address groundwater connectivity and to compare land-use impacts across multiple regions and scales. Approaches from landscape ecology that assess spatial patterns of, and synergies between, interlocking land cover may assist conservation managers in designing more resilient reefscapes.

“…Examples of A-class practices are reduced nitrogen application rates, legume fallow management and zero tillage. Although, the industry focus is to improve best practice management for water quality, in particular for DIN reductions, across the Wet Tropics only 26.7% of sugarcane land is currently managed for best practice (Star et al, 2018;Australian and Queensland Government, 2019a). The FGMs for C-Class were therefore adopted for the NPV analysis, however we conducted a sensitivity analysis to assess how a higher Bclass FGM changes the NPV.…”
