1
The spatio-temporal dynamics of fishing behaviour and its determinants in poor fishing communities Nick Hill 1,2 EJ Milner-Gulland 1, Marcus Rowcliffe 2, Guy Cowlishaw 2 1 Imperial College London. 2 Institute of Zoology, Zoological Society of London
2
Outline East Africa and small-scale fisheries Introduction to study site Livelihoods Effects on fishing behaviour
3
East Africa East Africa coastal population 22 million – 5-6% increase per annum Dependence on marine resources. Degradation: serious concern for livelihoods Failure to reduce degradation and poverty – Why?
4
Failure of fisheries management Why the failure? Behaviour poorly understood. Data aggregated spatially Data aggregated across fleet Consequence: Unable to predict response to management Policies and management unsuitable What is needed? Understanding of behaviour and its drivers
5
Study site Vamizi and Rongui Islands
6
Study site Tourism supports conservation and community development The only local development organization
7
Study site The marine resources are in excellent condition.
8
Vamizi Island communities Two community types: –Locals –Transients Each have different livelihoods
9
Hypothesis Livelihoods Fishing behaviour The role of fishing in livelihoods... …spatio-temporal dynamics of fishing: where, when and how much...effects... Fishing behaviour is driven by livelihoods: A livelihood: the capabilities, assets (including social and material resources) and activities required for a means of living. Objectives of fishing
10
Livelihoods Potential roles of fishing in livelihoods:
11
Livelihoods Livelihoods of transient communities? Livelihoods of local communities
12
Effect on fishing behaviour Temporal behaviour: – Frequency of fishing – Length of fishing trips – Investment in gear – Seasonality of fishing
13
Effect on fishing behaviour Environment Travel time Habitat Resource distribution Fishing location Landing sites Spatial behaviour Method: weighted suitability modelling Comparison of weightings for fishermen with different livelihoods Verification with fishing tracks
14
Effect on catch rates p < 0.05 n=22 n=35 n=28
15
Effect on catch rates
16
Conclusion Are spatio-temporal dynamics of fishing behaviour driven by livelihoods? Linking individual fishing behaviour to livelihoods may help us predict the effects of interventions.
