There’s not much scope for exaggeration in the story of how climate variation and change undermine the livelihoods of the world’s millions of fisherfolk (most of whom live in the tropics), because the truth is already pretty astonishing.

This is at least part of the message one gleans from a study published recently in Marine Policy, which traces the multiple pressures by which punishing climatic conditions wear away at the assets of fishing communities, leaving them ever more vulnerable to poverty.
Some of the impacts are fairly direct, like the effect of changing water temperatures and more frequent storms on coral bleaching and fish stocks. But others are somewhat insidious, resulting from actions taken outside the fisheries sector altogether. Measures to curb the impacts of flooding on agriculture, for example, may drastically reduce fish production in river basins.
Unlike much previous research, the Marine Policy study (whose authors are from the WorldFish Center and partner institutions in Canada, Germany and the UK) extends the analysis of climate change beyond direct effects on fish stocks – the “natural capital” of fishing communities – to catalogue the damage to their physical, financial, human and social capital as well.
For example, more frequent and severe storms destroy fishing communities’ boats and gear, while disrupting market channels as well as education and other services. Extreme weather also takes lives – killing twice as many women as men at some locations, because traditional roles restrict females largely to the home, where they are more vulnerable.
Tempering the bad news with good, the authors point to a “diverse portfolio” of measures that can strengthen the assets of fisherfolk in the face of climate change. Some of these build on the large “stock of knowledge and experience” that fishing communities have gained from constantly coping with uncertainty. But given the unprecedented pace and degree of the changes now unfolding, the study argues that new approaches are needed as well, such as insurance schemes; forecasting and early warning systems; and more supportive policies and institutions.
Investing in those and other measures, the researchers argue, is a win-win proposition, which will protect critical economic interests (including the US$86 billion worth of fish products traded annually), while reducing the poverty and vulnerability of the people engaged in small-scale fisheries.
