Abstract
The study examined the fish farmers‟ perceived environmental effects of dam operation and coping strategies among fish farmers in Ikere George dam, Iseyin Oyo state. Multi stage sampling technique was used to select 102 respondents in the study area. Data were collected through the use of interview schedule and were analysed using descriptive statistics such as percentage and frequency, while chi-square and PPMC were used to analyse hypotheses at p < 0.05. The result revealed that majority (54%) of the respondents below 40 years, with males predominantly higher than females. Also, 71.6% were married and 58.8% had educational attainment below secondary school. Challenges identified were disruption of movement of aquatic animals (137), blockage of migrations of aquatic species (135) and problem of overcrowding in the community (129) were prominent perceived effects of dam operation. The result further showed that migration (99) and planting of trees (146) were the most commonly used coping strategies. Chi-square showed that there was significant relationship between socio-economic characteristics of the respondents and perceived effects of dam operation except religion which was not significant (p>0.05). PPMC analysis revealed that there was significant relationship between coping strategies used (r=0.687, p=0.000). It is therefore recommended that proper training and adequate facilities should be given to fish farmers to ensure sustainability of the dam.
Highlights
Dams have made important contributions to human development, and the benefits derived from them have been considerable (World Commission on Dams, 2000)
There is a great deal of uncertainty about the consequences of dam removal (Aspen Institute, 2002; Hart et al, 2002), the unknowns related to the extent, magnitude, and timing of physical and ecological outcomes (Heinz center, 2001; Hart et al, 2002)
The general objective of this study is to examine fish farmers‟ perceived environmental effects of Dam operation and coping strategies used in Ikere Dam Oyo state
Summary
Dams have made important contributions to human development, and the benefits derived from them have been considerable (World Commission on Dams, 2000). There is a great deal of uncertainty about the consequences of dam removal (Aspen Institute, 2002; Hart et al, 2002), the unknowns related to the extent, magnitude, and timing of physical and ecological outcomes (Heinz center, 2001; Hart et al, 2002).
