Cordelia Moore and colleagues write in The Conversation (25.8.16) about more effective ways that governments can manage marine reserves, in tandem with economic interests and resource exploration.
‘When it comes to conserving the world’s oceans, bigger isn’t necessarily better. Globally, there has been an increasing trend towards placing very large marine reserves in remote regions. While these reserves help to meet some conservation targets, we don’t know if they are achieving their ultimate goal of protecting the diversity of life.
‘In 2002, the Convention on Biological Diversity called for at least 10% of each of the world’s land and marine habitats to be effectively conserved by 2010. Protected areas currently cover 14% of the land, but less than 3.4% of the marine environment.
‘Australia’s marine reserve system covers more than a third of our oceans. This system was based on the best available information and a commitment to minimising the effects of the new protected areas on existing users. However, since its release the system has been strongly criticised for doing little to protect biodiversity, and it is currently under review.
‘In a new study published in Scientific Reports, we looked at the current and proposed marine reserves off northwest Australia – an area that is also home to significant oil and gas resources. Our findings show how conservation objectives could be met more efficiently. Using technical advances, including the latest spatial modelling software, we were able to fill major gaps in biodiversity representation, with minimal losses to industry.’
