Abstract:
Human-elephant conflict (HEC) is recognised as a common problem across the entire area in
which the Asian elephant (Elephas maximus) ranges. Mitigating this conflict has become a
major challenge in conserving this endangered species which has been listed on Appendix 1
by the Convention on International Trade in Endangered Species of Wild Fauna and Flora
(CITES) since 1973. Fragmentation and loss of natural habitat are considered to be the
major factors contributing to HEC in Asia. The example of Sri Lanka is illustrative. There
has been a loss of nearly 50 percent of its dense forest cover during the last five decades.
This massive loss of forest cover, with concomitant fragmentation of the remaining elephant
habitat, has exacerbated HEC across the entire elephant range in Sri Lanka. Although
several policies have been implemented in response, they show no sign of resolving the
HEC-related issues satisfactorily. Thus, the issues involved with conservation of elephants
and mitigation of HEC in Sri Lanka call for new strategies.
The main objective of this thesis is to examine the economic issues involved in conservation
of the Asian elephant and mitigation of HEC in Sri Lanka in order to suggest effective
economic management strategies to ensure the long-term survival of this species of wildlife.
This study builds on the view that Sri Lanka's basic constraint in conserving elephants is that
confinement of elephants to the existing protected area network is incompatible with the
long-term survival of its wild elephant populations. Their survival depends on some access
to farmlands in the vicinity of the protected areas, for instance access to move across
farmland from one isolated habitat to another. However, utilisation of such private lands
inevitably results in conflicts with farmers. Furthermore, such a policy can also have an
adverse effect on elephants unless farmers are compensated adequately and promptly for the
damage caused by elephants to encourage farmers to allow elephants some access to their
farming lands. This thesis examines specifically whether by establishing a scheme financed
by those who regard the elephant as an asset, it is possible to obtain a Paretian improvement
in this situation. It also explores whether farmers in the areas where wild elephants interfere
with agriculture would be willing to contribute to such an insurance scheme and to what
extent.

The analyses presented in this thesis are based on the results from two sets of contingent
valuation surveys. One involved a sample of urban residents in three selected major housing
estates in the vicinity of Colombo city. The survey elicited their willingness to pay (WTP)
for the conservation of the elephant and to contribute to a publicly funded insurance scheme
to compensate farmers for the economic losses caused by this species. The other survey was
conducted by taking a sample of HEC-affected farmers chosen from six selected villages in
the Northwestern province of Sri Lanka. It elicited their WTP for the above scheme. It also
assessed the farmers' attitude towards an integrated economic approach aimed at raising
their tolerance of the presence of elephants on their farming lands. Together with the other
fundamental statistical tools, both logit and probit regression models were estimated to
analyse the respondents' responses to the payment principal questions and to identify factors
that influenced their responses and value judgments.
The findings of this thesis indicate that there is a strong economic case for the conservation
of wild elephants in Sri Lanka. It is argued that extinction of the current elephant population
in Sri Lanka would result in a Kaldor-Hicks social loss. This implies that compared to the
absence of wild elephants in Sri Lanka, the current situation involves a Kaldor-Hicks
benefit. The results obtained from two major empirical analyses show that elephants in Sri
Lanka are a net asset and not a net pest: the financial support of the urban residents to
maintain the present population of elephants in Sri Lanka exceeds the estimated costs that
elephants impose on farmers in the HEC-affected areas; the possible public support of
farmers plus urban dwellers significantly exceeds the financial requirement of the insurance
scheme proposed in this study for perpetuity. These results suggest that the community as a
whole will experience a net economic benefit from ensuring the survival of wild elephants in
Sri Lanka. Consequently, the results of these analyses also indicate that the nation will suffer
a net economic loss i f wild elephants become extinct in Sri Lanka. The overall findings of
this study provide an improved economic assessment of the value of the elephant in Sri
Lanka and a basis for wildlife authorities to explore new strategies and formulate
appropriate policies for conserving this endangered species.
