Politicians are notoriously wary of talking about food.

Nervous that anything they say publicly about changing the system will be construed as hiking prices of, or affecting access to, the basic human right that is food.

The main party manifestos are not promising enough. This means the vital questions on how policies must help farmers in climate adaptation and protecting nature - crucial for food production, wildlife, and our well-being - too often get weak responses or receive too poor a debate.

Yet there is no greater challenge. Over the next decade, as climate extremes multiply resulting in increased droughts and floods, governments must ensure a transformation to resilient farming everywhere. We need to be sure our future politicians and government get this.
