“Unveiling the Impact of Rising Ocean Temperatures on Indonesia’s Fisheries: A Comprehensive Analysis”

New Report Highlights Climate Change Impact on Indonesia’s Fisheries

A recent report co-authored by a team of experts from the World Bank, MMAF, UBC, UNIBE, and BRIN sheds light on the significant challenges that rising ocean temperatures pose to Indonesia’s fisheries sector. The report, which provides a detailed analysis of the current and projected impacts of climate change on Indonesia’s marine ecosystems, highlights the urgent need for action to ensure the resilience of the country’s ocean economy.

Indonesia, with its 17,504 islands and extensive coastline, relies heavily on its oceans for economic prosperity, food security, and employment. The fisheries sector, in particular, plays a crucial role in the country’s economy, contributing $26.9 billion annually and supporting over 7 million jobs. However, the sector is facing increasing threats from climate change, including rising water temperatures, more severe storms, and sea level rise.

According to the report, Indonesia’s sea surface temperatures have already warmed by 0.18°C per decade over the past 30 years, with further increases projected in the coming decades. Under a high emissions scenario, sea surface temperatures could rise by as much as 3.68°C by the end of the century, leading to significant changes in marine ecosystems and fish stocks.

The report uses advanced modeling techniques to assess the potential impact of these temperature rises on 54 key fish species in Indonesia’s waters. The analysis reveals that some species, particularly demersal and pelagic species, are likely to be most vulnerable to the changing ocean conditions. Maximum catch potential is projected to decline by 20-30% under a high emissions scenario by 2050, with significant implications for both artisanal and industrial-scale fisheries.

In response to these challenges, the Indonesian government has recognized the importance of building a climate-resilient marine and coastal economy. The report highlights the government’s efforts to invest in infrastructure, technology, capacity-building, and governance to support a sustainable fisheries sector. However, the authors stress the need for further research to guide policy and investment decisions, particularly at the sub-national and species-specific levels.

Overall, the report underscores the urgent need for coordinated action to address the impacts of climate change on Indonesia’s fisheries. By investing in research, planning, and sustainable management practices, Indonesia can work towards a more resilient ocean economy that supports both the environment and the livelihoods of its people.
