Cyanobacterial harmful algal blooms (CyanoHABs) are increasingly being reported worldwide owing to several reasons, including widespread eutrophication and enhanced scientific monitoring. Catchment and water management, organisations, industry, farmers and local governments are all confronting the effects of climate change, which stimulate the growth of cyanobacteria and affect the efficacy of adaptation measures in water systems. To tackle climate change and CyanoHABs growth, actors at different levels require both ‘top-down’ and ‘bottom-up’ assessments to help them in formulating and implementing adaptation measures. Potential solutions must also be assessed locally to limit associated adverse effects, in particular, negative effects on water quality. Thus, having a better understanding of the synergies, conflicts and trade-offs between adaptation practices and climate-change effects on CyanoHABs makes a valuable contribution to a more integrated climate policy and the effective climate-proofing of our water bodies. This article examines adaptation practices focused on tackling CyanoHABs occurrence in a changing climate. It fills an important gap between a major environmental problem and potential solutions. The practices and measures advanced as a result of the analysis can be used by persons with different expertise and skill levels for improving the relevant institutional frameworks and policies to protect their local water bodies.
