Many temperate crops require winter chilling to initiate flowering or fruit ripening, and orchards may need to shift to colder areas.

New Zealand is a net exporter of many fruit and vegetables. While climate-change induced food shortages are not an imminent risk, some crops may be affected by rising temperatures and extreme weather.
The development of an industry in edible insects such as these mopane caterpillars has been slow.

As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
A new IPCC report has called for radical changes in food production to avoid catastrophic climate change. Rice-fish farming and mixed crops could help.
