Rice farming warning: Scientists say the world's most important food is pushing Earth beyond safe environmental limits

For billions of people, rice is more than a daily meal; it is the foundation of food security, culture and livelihoods.

Every grain harvested represents centuries of agricultural knowledge and feeds communities across Asia, Africa and beyond.

Yet the crop that sustains more than half of humanity is now at the centre of a growing environmental concern.

A new international study has found that modern rice production is placing mounting pressure on Earth's climate, freshwater resources and nutrient cycles, raising questions about whether today's farming practices can continue without destabilising the natural systems they depend upon.

Rather than questioning rice itself, scientists argue that the findings highlight an urgent need to rethink how this indispensable crop is cultivated for a rapidly growing world.Why rice farming is becoming a major challenge for climate, water and food securityRice occupies a unique place in global agriculture.
