Helping Managers Understand Land-to-Sea Connections
Working Group Goals
1. Enhance and synthesize information about land-use impacts on fisheries by conducting analyses of existing data to quantify the relationship between land-use change, river run-off, habitat loss and fishery production.
2. Develop a model that can predict how and where river run-off affects coral reef fisheries, ensuring that the model is flexible so it can be adapted to consider a variety of land uses and fisheries, especially in data-poor regions.
3. Develop an approach that prioritizes management decisions, ensuring that any such decisions take into account connections between land and sea.
- What is the impact of different land-uses on fisheries and coastal livelihoods?
- Where are the most cost-effective priorities for management intervention —on the land and sea — to secure fisheries and livelihoods?
- Can the positive impacts of traditional fisheries management actions offset the negative impacts from land-based activities under different climate change and socio-economic scenarios?
- What is the consequence of land- and sea-based policy change on coastal fisheries?
1. Conduct a meta-analysis of land-use impacts
- Synthesize disparate data sources on individual processes that address impacts from land and sea.
- Develop multiple data-based models that link climate and weather, land-use change, water quality, habitat quality and fisheries production.
- Integrate existing data sets with new data from field experiments.
2. Conduct field experiments, which may include:
- Completing a study demonstrating how poor land-based practices affect bumphead parrotfish — an important food species — in the Kia District of the Solomon Islands.
- Measuring the differences in vulnerability on coastal fisheries and social factors based on a variety of land-based influences on Fiji.
- Completing a study on the impacts of palm oil on fisheries on Papua New Guinea.
3. Develop a model for predicting land-based impacts to fisheries.
- Develop the model based on the habitat dependency of different fish species and information on land-based impacts to habitats to estimate fishery catch potential.
4. Develop a “return on investment” framework to identify priority management actions (land or sea) to achieve a planning goal.
- The return will be measured based on the benefits of managing land to fisheries relative to converting it to a proposed land use.
The researchers will evaluate a range of current and future land-use scenarios to determine trade-offs between economic development, conservation, fisheries and livelihoods.
