4/n
3. Asia continues to dominate rice emissions globally, but the fastest growth in emissions comes from Africa, albeit starting from a low baseline.
5/n
4. There are effective mitigation strategies to reduce GHG emissions: replace continuous flooding with intermittent flooding; reduce chemical fertilizers and straw additions to a level not affecting crop yield; no-tillage.
6/n
5. Yet effective, these straightforward and well-known mitigation strategies can only reduce GHG emissions by about 10%, leaving most of the emissions unabated.
3/n
2. The growth comes from more land under rice cultivation, more chemical (70% increase since 2000) and organic inputs per hectare, and more crops per year (up to three in some countries).
