    Marine harmful algal blooms, human health and wellbeing : challenges and opportunities in the 21st century

    Microalgal blooms are a natural part of the seasonal cycle of photosynthetic organisms in marine ecosystems. They are key components of the structure and dynamics of the oceans and thus sustain the benefits that humans obtain from these aquatic environments. However, some microalgal blooms can cause harm to humans and other organisms. These harmful algal blooms (HABs) have direct impacts on human health and negative influences on human wellbeing, mainly through their consequences to coastal ecosystem services (valued fisheries, tourism and recreation) and other marine organisms and environments. HABs are natural phenomena, but these events can be favoured by anthropogenic pressures in coastal areas. Global warming and associated changes in the oceans could affect HAB occurrences and toxicity as well, although forecasting the possible trends is still speculative and requires intensive multidisciplinary research. At the beginning of the 21st century, with expanding human populations, particularly in coastal and developing countries, there is an urgent need to prevent and mitigate HABs’ impacts on human health and wellbeing. The available tools to address this global challenge include maintaining intensive, multidisciplinary and collaborative scientific research, and strengthening the coordination with stakeholders, policymakers and the general public. Here we provide an overview of different aspects to understand the relevance of the HABs phenomena, an important element of the intrinsic links between oceans and human health and wellbeing.

    The IOC International Harmful Bloom Program : history and science impacts
    (Oceanography Society, 2010-09) Anderson, Donald M. ; Reguera, Beatriz ; Pitcher, Grant C. ; Enevoldsen, Henrik O.
    Harmful algal blooms (HABs) have become an important subdiscipline within oceanography. Heightened attention to this topic as well as significant research advances reflect the global nature of the problem and the development of strong national and international programs for HAB research and management. The planning, communication, coordination, and capacity-building activities of the Intergovernmental Oceanographic Commission (IOC) have been a key factor in this growth. Here, we highlight selected advances in science and management capacity for HABs and document the impressive growth of the field in the context of activities supported directly or indirectly by IOC. As we look to the future, the field has significant momentum and stability. Nevertheless, it will require scientific guidance and coordination going forward. With an appropriate commitment of resources from member states, the IOC HAB program can continue to be a major factor in the sustained growth of this important scientific discipline and its delivery of improved observation and management systems.
