As natural resources decrease, competition between humans and large
endangered wildlife increases, hindering the sustainability of animal
conservation and human development. Despite the multi-dimensional nature of
such interactions, proactive assessments that consider both the biosphere
and anthroposphere remain limited. In this study, we proposed a human
elephant conflict risk assessment framework and analyzed the spatial
distribution of risk at the baseline (2000–2019) and in the near future
(2025–2044) for Thailand, so that it may address the multifaceted
characteristics and impending effects of climate change. Future scenarios
were based on the combination of RCP45/SSP2 or RCP85/SSP5 and spatial
policy, with or without elephant buffer zones. The composite risk index,
comprised of hazard, exposure, and vulnerability, was constructed using the
geometric mean, and validation was performed with the area under the curve
(AUC). Our results projected a shift with increasing future risk toward
higher latitudes and altitudes. Increasing future risk (average +1.7% to
+7.4%) in the four forest complexes (FCs) in northwestern regions was a
result of higher hazard and vulnerability from more favorable habitat
conditions and increasing drought probability, respectively. Reduction in
future risk (average −3.1% to −57.9%) in other FCs in lower regions was
mainly due to decreasing hazard because of decreasing habitat suitability.
Our results also highlight geographically explicit strategies to support
long-term planning of conservation resources. Areas with increasing future
risk are currently facing low conflict; hence it is recommended that future
strategies should enhance adaptive capacity and coexistence awareness.
Conversely, areas with lowering future risk from a decrease in habitat
quality are recommended to identify buffer strategies around protected
areas to support existing large elephant populations.
