As the 2023 bleaching season comes to an end, the Western Indian Ocean (WIO) region can breathe a sigh of relief. Over the past three years, the WIO has experienced lower occurrences of coral bleaching, thanks to cooler seasons that have contributed to a positive trend in coral reef health. This encouraging development has brought hope to those dedicated to preserving and protecting these vital ecosystems. However, looming climate predictions indicate potential challenges ahead. In this blog post, we will explore the changing landscape of the WIO and discuss the importance of remaining proactive in our conservation efforts.
The current predictions point towards significant changes in climatic conditions in the WIO region. Both the El Niño-Southern Oscillation (ENSO, left) and the Indian Ocean Dipole (IOD, right) are expected to turn positive in the coming months, indicating the likelihood of warmer summers and widescale bleaching events. This projection raises concerns about the future health of coral reefs in the region.
While we cannot accurately predict the timing or severity of future bleaching events, these forecasts serve as a wake-up call to remain vigilant and proactive in our conservation endeavors. It is crucial that we take steps to mitigate the impact of bleaching events and secure the long-term survival of coral reefs and the rich marine biodiversity they support.
To address these challenges, CORDIO, along with its partners, is actively engaging in the Global Monitoring of Environment and Security in Africa (GMES and Africa) project. Through this collaboration, CORDIO will review and enhance coral bleaching predictors, ensuring improved accuracy and precision in predicting these events. By strengthening our understanding of the factors contributing to coral bleaching and knowledge management and sharing, we can better prepare for and mitigate its impact.
In addition to predictive measures, early engagement and training on coral bleaching observations are essential to empower our ground partners. By equipping them with the knowledge and skills necessary to identify and respond to bleaching events, we can ensure a timely and effective response in the years to come. Together, we can minimize the damage caused by bleaching and protect these vulnerable ecosystems.
While the predicted changes pose significant challenges, they also present an opportunity to renew our commitment to coral reef conservation. By acting collectively, we can make a meaningful difference in safeguarding the future of these fragile ecosystems. Let us embrace this chance to redouble our efforts and work towards a sustainable future for coral reefs in the WIO region.
From 17 to 18 June 2025, the CSIR, which anchors the Marine and Coastal Operations for Southern Africa (MarCOSIO) project under the auspices of the GMES and Africa, co-hosted the Southern African Regional Stakeholder Workshop at the CSIR International Convention Centre in Pretoria, South Africa.
The Marine and Coastal Observations for Southern Africa and the Indian Ocean (MarCOSIO) programme, part of the Global Monitoring for Environment and Security (GMES) and Africa initiative, supports the development of local capabilities, institutional capacity and access to technical resources to deliver Earth observation (EO)-based services for sustainable development in Africa.
In a landmark moment for continental space development, the Global Monitoring for Environment and Security (GMES) and Africa programme, which is the flagship Earth Observation (EO) initiative, has officially become an initiative under the African Space Agency (AfSA). This strategic integration marks a new chapter in Africa’s journey towards harnessing space science and technology for sustainable development, environmental resilience and policy innovation.
The MarCOSIO Team was excited to participate in Ocean Innovation Africa 2025, which took place from February 24-28, 2025, in Dar es Salaam, Tanzania, along with various partners from WIOMSA, CSIR, TAFIRI and ABALOBI.
Marine and Coastal Operations for Southern Africa and the Indian Ocean (MarCOSIO) through the generous funding of the African Union Commission (AUC) and the European Commission under the Global Monitoring for Environment and Security and Africa (GMES & Africa) project, sponsored Raisha to pursue 101-SA Ocean Governance Training Course in Cape Town, South Africa
Africa Marine and Coastal Operations for Southern Africa and Indian Ocean (MarCOSIO) consortium has acquired another able partner- Reef Conservation – in the second phase of the Global Monitoring for Environment and Security in Africa (GMES & Africa) project.
The GMES and Africa Marine and Coastal Operations (MarCOSIO) project (https://marcosio.org/) is the result of collaborative partnerships (Council for Scientific and Industrial Research (CSIR), ABALOBI, Benguela Current Convention, Coastal Oceans Research and Development Indian Ocean – East Africa, Institut Halieutique et des Sciences Marines, University of Dar es Salaam – Institute for Marine Science, Kenya Marine Fisheries Research Institute, Mauritius Oceanography Institute, National Sea Rescue Institute, National Sea Rescue Institute, Tanzania Fisheries and Research Institute, University of Eduardo Mondlane, West Indian Ocean Marine Science Association). MarCOSIO is funded through the African Union’s GMES and Africa programme and forms part of its Marine and Coastal Operations thematic area.
