Ahh the Pacific Islands...white sand, warm water, sun shining down....it sounds wonderful (especially for me - I'm having a 'year of winter' with my moving about). But things are changing, and perhaps nothing is quite changing on a global scale quite like the climate. If your a Pacific Islander, climate change is likely to be a huge problem. It all comes down to reliance on local resources, and in many cases these resources come from local marine waters. From a food perspective, Dr Johann Bell of the Secretariat of the Pacific Community and colleagues from around the globe predict things are going to change a fair bit....here's some highlights from the paper:
- Coral reef fisheries could decrease by 20% by 2050 - Skipjack tuna is may become more abundant in eastern Polynesia...but only because they have moved away from the western Islands where they currently support livelihoods
- Coastal aquaculture may become less efficient, but for the Islands with larger land mass, predicted increases in rain (and thus larger lakes, rivers, etc) freshwater aquaculture may become a more viable option.
Couple this with expected changes in sea level rise, adaptation will most certainly be needed if many of the Pacific Islanders are to face the challenges ahead.
