Landscape-based conservation approaches in the developing world: The case for Managed Elephant Ranges in Sri Lanka Sanjay Kalpage A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy Institute of Environmental Studies School of Arts & Social Sciences October 2013 THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Kalpage First name: Sanjay Other name/s: Rajnish Perera Abbreviation for degree as given in the University calendar: PhD School: Arts & Social Sciences Faculty: Institute of Environmental Studies Title: Landscape-based conservation approaches in the developing world: the case for Managed Elephant Ranges in Sri Lanka Abstract 350 words maximum: (PLEASE TYPE) While establishing protected areas (PAs) has helped conserve the Earth’s diminishing biodiversity, the ‘traditional’ view of conservation underlying this approach—perceiving nature as static, and considering people apart from nature—has compromised PA effectiveness. Moreover, competing land uses often hamper new PA establishment. Consequently, landscape-based approaches could better achieve conservation objectives while catering to human needs. Unfortunately, these approaches have often proved difficult to implement, especially in developing countries. This thesis explores how a landscape-based approach could address Sri Lanka’s most pressing conservation issue: human-elephant conflict resulting in the deaths of about 75 people and 200 elephants annually, and causing substantial property damage. Government policy makers are under tremendous pressure to resolve this conflict—as the endangered Asian elephant is a national icon—but their efforts have largely proved ineffective. Some conservation biologists have proposed a unique conflict-mitigation approach based on research showing that traditional ‘shifting agriculture’ creates optimal elephant habitat, and that differences in timing of land-use by farmers and elephants enables resource-sharing with minimal conflict (irrigated agriculture has been the conflict’s main driver). They recommend establishing ‘Managed Elephant Ranges’ (MERs) outside, but mostly adjacent to, PAs. My thesis focuses on implementing this approach within a particular landscape in southeast Sri Lanka. Given the problem’s complexity, I adopted an interdisciplinary approach—incorporating GIS-based spatial analysis, stakeholder analysis and economic modelling—to demarcate potential MERs, identify stakeholder needs (e.g. of farmers, government officials, NGOs, business-people), and estimate sources of economic value within the landscape (e.g. from nature tourism, carbon credits). Combining my results with lessons from other countries, I have developed a sustainable, economically viable MER implementation plan that meets key stakeholder needs. My approach constitutes a blueprint for implementing MERs in Sri Lanka’s human-elephant conflict areas, while my overall methodology has wider applications in areas of human-wildlife conflict worldwide. Ultimately, my research provides practical applications of natural capital valuation and sustainable natural resource use in a developing country context.
