ghana climate change vulnerability and adaptation assessment

epresentss a doubling of effective engine power over the past three decades (Finegold et al. ., 2010). Similarly, smallcanoes arenow often equipped with small (generally 8 hp) engines, again increasing effective range.Figure 6.7 Relativee time takenfor fisherss to reach their fishing groundsChange innet systems: Effort measured in terms of fishing tripss does not account for changes in net type, netconstruction, or net size, all of whichh enormously impact fishingg power. Detailed data on gear changes over timein Ghana are unavailable; however, field observations, interviews with fishers, and a few reports point tosignificantchanges (Finegold et al., 2010).To effectively double fishing effort, a fisher could double the length of net deployed. Dataa on changes in netlength are unavailable for Ghana, butare available for a Côte d’Ivoire canoe fishery for large pelagic species(targeting billfish, sharks, and tuna; Bard and Goran, 2001). Between 1984 and 2000, the average length of gillnets doubled and the fishery data system reported an increase inn fishing trips from low levels in 1984 (
