Monitoring

Community-based approaches to conservation and natural resource management are considered essential to meeting global conservation targets. Despite widespread adoption, there is little understanding about successful and unsuccessful community-based practices because of the challenges of designing robust evaluations to estimate impacts and analyse the underlying mechanisms to impact. Here we present findings from a national scale evaluation of the ‘locally managed marine areas’ network in Fiji, a marine community-based management initiative.

In 2016 a partnership was developed between the Tongan Ministry of Fisheries and James Cook University in Townsville, Australia. Its aim was to implement the first stage of a Tongan national coral reef monitoring project, and to provide an overview of the current status of Tonga’s Special Management Area (SMA) program. Since 2002 the Ministry of Fisheries has been heavily focused on expanding the SMA program, and communities throughout Tonga have been enthusiastic about introducing local marine management. As a result of this momentum, the Ministry has focused primarily on implementation.

Our global analysis of nearly 1,800 tropical reefs reveals how the intensity of human impacts in the surrounding seascape, measured as a function of human population size and accessibility to reefs (“gravity”), diminishes the effectiveness of marine reserves at sustaining reef fish biomass and the presence of top predators, even where compliance with reserve rules is high. Critically, fish biomass in high-compliance marine reserves located where human impacts were intensive tended to be less than a quarter that of reserves where human impacts were low.

This report was a collaboration Science and Conservation of Fish Aggregations, University of Hong Kong, Fiji Ministry of Fisheries, Wildlife Conservation Society, and the University of British Columbia (Canada).We conducted a seafood VCA for the coral reef grouper (Epinephelidae) fishery in Fiji with the goal of understanding the distribution of value gained from grouper along the trade chain, from fisher to consumer.

A hopeful vision of the future is a world in which both people and nature thrive, but there is little evidence to support the feasibility of such a vision. We used a global, spatially explicit, systems modeling approach to explore the possibility of meeting the demands of increased populations and economic growth in 2050 while simultaneously advancing multiple conservation goals.
