mixed systems & SLPwww.vslp.org Mixed systems = 2/3 population + food +
> ½ area is tilled by animal; but also hand or tractor (not shown)Scarce legumes; market distortion & farming systems
results show that:
CR are short-term resources: feed & Co.
CR to mulch with lower pressure (very ↑ production; or ↑ production + ↓ demand), but practices need to change. With higher pressure: increase of production is needed.
Each region has its own potential, challenges & options for more sustainable agriculture = no silver-bullet exists
