Abstract:
This study assesses the effectiveness of electric fences in reducing conflict between
wild elephants and the farming communities that reside in the adjoining areas of natural
habitats of wildlife in Sri Lanka. A household survey was undertaken by covering the
entire beneficiary farming families of an electric fence established with the support of
UNDP/GEF/SGP in Buddangala in Ampara District. Our analysis revealed how electric
fencing was significantly effective in reducing crop damage by 88% and livestock
depredation by 90% and property damage by 80%. Further 86% of householders state
that after the installation of the fence, their food security levels are somewhat secure to
very well secure and the home garden extent has increased from 2%-26%. About 85%
state that the cropping pattern has significantly increased where farmers now grow
different types of crops including perennials and certain cash crops. The time spent on
chasing away wildlife has reduced significantly, as much as from 55% to 14% after the
installation of the electric fence. More than 80% say the fence is effective and 92% say
their tolerance level for tribal elephants have improved as a result and 93% say that they
are appreciative of the value of the elephants in the area and aware of the importance
they have for bio diversity, ecological, historical, cultural and religious values. About
70% say that their quality of life ha? improved. Respondents state that they are willing
to pay for establishing a suitable mechanism to pay for the damage and conservation of
elephants. Our analysis suggests that the total net present value of the cost of electric
fence in this area was much less than the net benefit of it by the community. The overall
findings reveal that there is significant improvement in social wellbeing and the
livelihood of the farming communities in the study area. However, we observed that
mere presence of electricity did not minimize fence breakage by elephants and entering
into fenced areas. Thus, it is suggested that, location of fences in relation to landscape
factors, maintenance of effective non-electrified fences and proximity of fences to areas
of high elephant concentration are significant determinants of fence performance in
mitigating human-elephant conflicts.
