DESCRIPTION:How people respond to environmental decline can reduce pressure
  on ecosystems or intensify it. We examine factors leading some fishers to
  respond to declining reef fish abundance by fishing harder\, focusing on 
 how they perceive the cause of decline and how they are connected to other
  fishers and marine resources. We do so by drawing on comprehensive struct
 ured survey and network data from 656 reef fishers across five co-managed 
 coastal communities in Kenya. Among fishers who perceived declining abunda
 nce\, we distinguished between endogenous causes arising within the fisher
 y\, such as overfishing and illegal gears\, and exogenous causes originati
 ng outside it or beyond local control\, such as pollution and climate chan
 ge. Most fishers (571/656) perceived a decline in reef fish abundance betw
 een 2015 and 2019\, and nearly half of those (282/571) reported fishing ha
 rder in response – amplifying the declining reef fish abundance. Fishers
  who attributed resource declines to endogenous causes were more likely to
  fish harder than those who attributed it to exogenous causes\, contrary t
 o expectations that recognizing local causes should encourage restraint. S
 ocial relationships among fishers  were unrelated to perceptions of\, and 
 responses to\, decline\, yet the overlap between social relationships and 
 resource dependence mattered. Specifically\, fishers connected to others t
 argeting the same resources were less likely overall to attribute decline 
 to local causes but were more likely to do so when those connected fishers
  shared that interpretation. These shared-resource relationships\, and dep
 endence on multiple ecologically connected resources\, were also associate
 d with fishing harder. Our findings show that relationships among people a
 nd resources can shape both how environmental change is understood and how
  people respond. Structures that could support coordination may also inten
 sify competition when confidence in community-wide restraint is limited\, 
 creating feedbacks that further threaten fisheries sustainability.
