Great Barrier Reef
The Great Barrier Reef is rare in that most of its threats come in the form of onshore industry. Before the recent push to expand coal ports, the main industry in the firing line was agriculture. Rainwater falls inland, travels across farms picking up pesticides, dirt and fertiliser and washes down the rivers, through deltas and out onto the barrier reef where it leads to increased pollution and nitrogen levels in the water.
Increased nitrogen in the water is not good for the reef. Amongst other things it has catalysed the spawning cycles of Crown of Thorns Starfish (COTS). Traditionally COTS would spawn on the north of the reef, around Cairns, once every 20 years or so. But in recent years the dramatically increased numbers of these starfish, whose primary food source is coral, have been significantly damaging the reef. Boats are now patrolling the reef specifically tasked with eradicating them using a toxic injection but can only address a small percent of the starfish outbreaks.
UNESCO’s concerns however are now also focused on the issue of industrial development along the reef. Queensland has one of the largest deposits of coal, and with developed markets slowly turning their back on dirty energy, there’s huge momentum to dig it up and ship it out as fast as possible before falling prices make it no longer viable. To do this requires unprecedented amounts of dredging, both to expand existing coal ports and create new ones, many inside the Barrier Reef World Heritage Area.
Dredging is problematic for a few reasons. Firstly it digs up seagrass meadows, removing valuable grazing areas for dugongs and turtles; secondly it can stir up a toxic soup of heavy metals which threaten the health of marine life. And lastly, the dredge spoils are then dumped back out onto Barrier Reef waters and can travel for miles up the coast clogging coral polyps and smothering reef systems.
Agriculture, however, has taken huge strides forward in both accepting its responsibility for deteriorating water quality and in trying to do something about it. Project Catalyst is one example where Farmers like Gerry Deguara (pictured), government agencies, the Coca-Cola Foundation and WWF, have been working together to develop new farming methods that limit the run-off from farms in order to protect the reef with the added benefit of increase farm productivity. This makes both good ecological sense for the reef and good business sense for Gerry and many others like him.
Responsible and sustainable ecological stewardship of the reef makes sense for more than just those that rely upon agriculture for their livelihoods too. The tourism industry, one of the largest employers in Queensland, brings in $6 billion annually and is also actively engaged in trying to protect the reef. For every tourist who visits the reef, tour operators pay an environmental management charge which ostensibly goes to ensure the reef is protected. Understandably, both tourism operators and farmers feel there’s a real equity issue on the reef. They are making significant efforts to protect the reef’s natural capital and the sustainability of their businesses whilst the dredging and dumping for ports has the potential to negate the benefits of their efforts and harm the reef. We can and should be making better business choices for our energy needs too.
WWF’s Living Planet Report 2014 echoes the voices of people we met on the Great Barrier Reef. Government policy moves too slowly, with the pressure of climate change also threatening this natural wonder, industry stewardship and Reef safe development standards are the only positive and practical solutions to the securing its future. The Great Barrier Reef, as with many other unique and special places on our planet, is more than capable of generating enormous annual revenue and livelihoods for those who live and work alongside it in a sustainable way. But the Great Barrier Reef is just one example. What is at stake is not just the World Heritage status of this very special place and not just the livelihoods of the many that depend upon its good health.
We all depend upon a healthy planet for our survival. It provides every single one of us with the food, water and energy we need to be able to live and thrive after all. Like Gerry, we can make better choices that recognise the real value of our planet’s natural capital. Choices that are good for us, good for the planet ...and good for business too.
catchment run-off is one of the biggest threats
Water running off catchments collects farm fertilizer, pesticides and soil, and flushes these pollutants out onto the Reef. The impact on corals and seagrass, and the species that rely on them, is immense.
If stuff that runs off our farm is affecting the Reef we need to do what we can to reduce it. And that’s the idea of this, to get proactive and show what can be done. Hopefully that will lead to change within the industry.
