Mariculture, a type of aquaculture where marine organisms are cultivated in open ocean or brackish waters, is thought to contribute to “blue growth” for the sustainable development of island and coastal states in the West Indian Ocean. Small-scale community-based mariculture projects have increasingly gained popularity and attention from governments, the private sector, social entrepreneurs, as well as conservation and development agencies.
While mariculture has had a positive impact when it comes to supporting local livelihoods, many questions still remain when it comes to its development impact and scalability. A new report, co-authored by centre researcher Max Troell, outlines a diagnostic framework that is designed to assist decision-making for assessment and planning around sustainable and equitable mariculture.
A new publication, co-authored by GEDB researcher Max Troell and published by The Australian Centre for International Agricultural Research (ACIAR), outlines a diagnostic framework that is designed to assist decision-making for assessment and planning around sustainable and equitable mariculture.
Mariculture as an equitable approach
Livelihoods through mariculture farming mainly come from commodity species, meaning they are often meant for an international market with high market prices instead of local consumption. The report points out that effective implementation of mariculture in the West Indian Ocean has potential for creation of new local employment and livelihood opportunities for coastal and island communities.
However, the report also highlights that mariculture must operate sustainably and based on equitable sharing of the benefits. This means being in line with the Sustainable Development Goals (SDG). Cecile Brugere, a co-author of the study explains, “’Benefit sharing’ is both a way of thinking and a practical process to distribute the monetary and non-monetary benefits of resource utilization across the economy and its stakeholders, generating broad-based growth and progress towards social equity outcomes.” She also points out that benefit sharing is in line SDGs, and moves away from ‘business as usual’ economic development.
To help decide if a potential mariculture operation would be equitable and sustainable, the authors developed a diagnostic framework that outlines aspirational outcomes – a benchmark of what each mariculture initiative should aim to achieve.
The diagnostic framework
The framework is broken down into six outcomes:
1. Space – mariculture area will be located maintains environment and supports livelihoods
2. Habitats – use coastal habitats that support ecosystem services
3. Biosecurity – functional integrity of ecosystem is not compromised
4. Incomes and livelihoods – livelihood opportunities and benefits for community residents
5. Economic growth – financially viable and promotes socially responsible national growth
6. Gender and youth – equitable access to opportunities and benefits
Under each outcome there is a diagnostic question, and criteria to answer that question, which tests if a potential mariculture operation would be able to achieve the outcome. If the answer is no, then the framework also provides guidance on what actions should be taken to achieve the outcome.
For example, in outcome three, biosecurity, the diagnostic question is: “Will there be negligible risk of mariculture introducing invasive species or pathogens that could undermine current or future livelihoods?”. The framework then provides a number of steps to finding the answer. In this case, one example of a step is to “Check compliance with legislation on the introduction and management of non-indigenous species.” Finally, the framework provides suggestions if the answer is “no” or unknown. In the case of the biosecurity outcome, it advises that the mariculture must comply with better management and legislation.
While this tool can help decide if mariculture is the right option in that area, Troell warns that it is not failsafe. “It is important to note that this diagnostic framework will not solve all the potential problems or capture all the opportunities that may come with mariculture development, but it will help guide and structure how to carry out assessments of such activities.”
