Aquaculture is the fastest-growing food sector globally.

Nature-based solutions (NbS) in aquaculture have the potential to address these challenges while delivering livelihood and biodiversity co-benefits. Yet, more knowledge, policies, and incentives are needed to enable access and adoption, particularly for small and medium-scale aquafarms.

What are nature-based solutions in aquaculture?

NbS in aquaculture are actions to protect, conserve, restore, and sustainably manage natural or modified aquatic ecosystems while supporting the cultivation of species for food security and livelihoods.

NbS have been recognized globally for their critical role as a climate solution. Yet, NbS in aquaculture is relatively new and not well understood. Through AQUADAPT, IDRC aims to build a critical evidence base and shared vision of and commitment to socially inclusive NbS in aquaculture.

Rising demand for aquatic foods requires a massive increase in production, specifically in Asia, where the majority of the world’s aquaculture is concentrated.

While aquaculture’s contributions to food security and incomes are essential, the sector’s rapid growth in AsiaPacific risks deepening climate change vulnerabilities and exacerbating environmental degradation and social inequality.

How is AQUADAPT advancing nature-based solutions in aquaculture?

AQUADAPT’s Overall Objective To enable more resilient and sustainable aquaculture food systems by harnessing the potential of NbS for climate-vulnerable communities, including people of all genders and marginalized groups, in Asia-Pacific.

AQUADAPT’s Specific Objectives Build Knowledge To generate new knowledge on how socially inclusive NbS in aquaculture can contribute to climate change adaptation, biodiversity conservation, and food and nutrition security.

Enable Access To enhance equitable access to the benefits of socially inclusive NbS in aquaculture for all genders and marginalized groups (e.g., youth, Indigenous Peoples) through inclusive technologies, policies, markets, and finance.

Develop a Shared Vision To inform public and private stakeholders on socially inclusive NbS innovations in aquaculture, how to implement and enable them, and how to assess their benefits and trade-offs.

Nature-based practices and aquaculture adaptation to climate change in Thailand and Vietnam

Making the monitoring of nature-based climate solutions in aquaculture in Southeast Asia more gender-responsive: What gets measured, gets done

Lead Institution: Chiang Mai University, Thailand Countries of focus: Thailand and Vietnam The Unit for Social and Environmental Research (USER) at Chiang Mai University and partners seek to increase the available sustainable options for small and medium-scale aquaculture farms facing climate change challenges in Thailand and Vietnam. They will enhance the resilience of aquaculture stakeholders by supporting the innovation, evaluation, and adoption of inclusive, nature-based practices. The project members are assessing NbS’ potential to address climate change challenges under different ecological, market, and social conditions, as well as obstacles and incentives to innovation and adoption at different scales. They especially seek to understand how NbS may promote more just and inclusive development for women, migrant labourers, Indigenous Peoples, and other marginalized stakeholders. In this way, the project will contribute to making aquaculture development both people-centred and nature-based.

Lead Institution: Asian Institute of Technology (AIT) Countries of focus: Philippines, Thailand, and Cambodia Led by the Gender in Aquaculture and Fisheries Section (GAFS) of the Asian Fisheries Society and administered at AIT, this project challenges how monitoring is being conceptualized and carried out, developing a gender monitoring schema to ensure the integration of gender equity and social inclusion in NbS in aquaculture systems and projects. Taking women’s and men’s specific needs into account, the monitoring schema aims to capture the nuanced and intersectional processes in which women’s empowerment is realized and show how gender responsive monitoring schema can prove effective for environmental outcomes. The project will pilot the monitoring schema in three locations: Philippines (seaweed), Thailand, and Cambodia (rice fish).

Leveraging climate-smart shrimp aquaculture as an inclusive nature-based climate solution for smallscale farmers in coastal Indonesia Lead Institution: World Resources Institute (WRI) Indonesia Country of focus: Indonesia WRI Indonesia and partners are building resilience by integrating mangrove restoration with shrimp aquaculture as an alternative to conventional shrimp farming, which degrades these valuable ecosystems. Mangroves, combined with supportive infrastructure, help reduce contamination from shrimp ponds by filtering water and can protect against storms and floods. This project seeks to identify and improve the most cost-effective, gender-responsive, and naturefriendly strategies while building the capacity of small-scale aquafarmers to help enhance coastal community resilience.

multitrophic aquaculture systems (IMTA). In multitrophic systems, one species’ waste (e.g., shrimp) feeds others (e.g., seaweed or “macroalgae”), reducing water contamination and enhancing productivity. Not only will algae-based products supply additional income opportunities, but researchers will also test heat-sensitive algae as a climate change adaptation and alternative to antibiotic overuse.

Algae can interfere with the communication of pathogenic bacteria (“quorum sensing”), potentially controlling diseases and reducing antimicrobial resistance.

Climate-Adaptive, Inclusive, Nature-based Aquaculture (CAINA) in Malaysia and Solomon Islands Lead Institution: WorldFish Countries of focus: Malaysia and Solomon Islands WorldFish and partners are developing clear standards for NbS in aquaculture and tools to measure their environmental, social, and economic performance, including their contribution to climate adaptation. This will help ensure that the benefits of NbS are maximized while addressing potential trade-offs. Definitions and standards will be tested and refined through case studies in Malaysia and the Solomon Islands. The team will also develop a comprehensive survey of current aquaculture activities in these countries and assess their current and future vulnerabilities to climate change. Overall, the project will identify and develop pathways for scaling NbS in Southeast Asia and the Pacific (SEAPAC).

Building an evidence base for inclusive naturebased climate solutions in small-scale aquaculture for sustainable aquatic food systems in the Philippines and Cambodia

Lead institution: James Cook University (JCU) Country of focus: Vietnam JCU and the Research Institutes for Aquaculture No. 1, 2, and 3 are examining the ecological and economic potential of circular approaches to fish feeding for grouper and other marine species. Specifically formulated fish feeds decrease risks of disease and eutrophication inherent to feeding wildcaught whole fish. By utilizing byproducts from aquaculture and other industries, a circular economy approach can further enhance nutrient capture in the human food chain and decrease the environmental footprint of fish farming.

By optimizing feeding techniques and developing nutrient dense pellet formulas, research will enable small farmers to reduce costs, increase yields, and improve water quality while creating new opportunities for the local private sector.
