Unknown effectiveness (limited evidence)

Implement a ‘no-feeding of wild primates’ policy

1A controlled before-and-after study in Japan found that reducing food provisioning of macaques progressively reduced productivity and reversed population increases and crop and forest damage. Assessment: unknown effectiveness — limited evidence (effectiveness 40 %; certainty 20 %; harms 0 %).


Put up signs to warn people about not feeding primates

3One review study in Japan found that after macaque feeding by tourists was banned and advertised, the number of aggressive incidents between people and macaques decreased as well as the number of road collisions with macaques that used to be fed from cars. Assessment: unknown effectiveness — limited evidence (effectiveness 30 %; certainty 10 %; harms 0 %).


Resettle illegal human communities (i.e. in a protected area) to another location

5One review on gorillas in Uganda found that no more gorillas were killed after human settlers were relocated outside the protected area, alongside other interventions. One before-and-after study in the Republic of Congo found that most reintroduced chimpanzees survived over five years after human communities were resettled, alongside other interventions. Assessment: unknown effectiveness — limited evidence (effectiveness 65 %; certainty 15 %; harms 0 %).


No evidence found (no assessment)

7We have captured no evidence for the following interventions:

  • Build fences to keep humans out
  • Restrict number of people that are allowed access to the site
  • Install ‘primate-proof’ garbage bins
  • Do not allow people to consume food within natural areas where primates can view them.
