Prof. D.A.C. Suranga Silva has spent three decades advancing a vision of tourism that restores ecosystems, empowers communities, and accelerates the UN's Sustainable Development Goals across South and Southeast Asia.
UN Sustainable Development Goals at the Core of This Work
The Philosophy
Prof. Suranga Silva argues that conventional tourism has treated the natural world as an inexhaustible resource. His scholarship inverts this premise: destinations are living ecosystems, and every visitor interaction is an opportunity to restore rather than extract.
Drawing on three decades of field research across Sri Lanka, the Maldives, Thailand, and beyond, his framework integrates ecological carrying capacity, community economic sovereignty, and cultural integrity into a unified model for regenerative tourism governance.
This is not romanticism — it is rigorous, evidence-based policy science aligned directly with the United Nations' 2030 Agenda for Sustainable Development.
Sustainable tourism is not a compromise between growth and conservation — it is the only path to both. When we protect what makes a place extraordinary, we protect the future of travel itself.
— Prof. D.A.C. Suranga Silva
Framework
Planet
Establishing science-based carrying capacity thresholds, protecting biodiversity corridors, and embedding regenerative land-use principles into national tourism policy. Tourism footprints must be measured, managed, and ultimately reversed.
People
Designing community-based tourism models that keep revenue local, respect indigenous knowledge systems, and position residents as architects of their own destination futures — not passive recipients of outside investment.
Prosperity
Building transparent value chains that distribute benefit equitably across gender, age, and social strata. Sustainable prosperity is measured not by aggregate GDP growth but by the breadth of who shares in tourism's economic dividends.
2030 Agenda Alignment
Measured Impact
Scholarship Focus
Ecology × Tourism
Investigating how wildlife-based tourism can fund habitat protection and create economic incentives for communities to become conservation stewards in Sri Lanka's dry-zone national parks.
Coastal Governance
Developing integrated coastal zone management frameworks that balance tourism receipts with coral reef preservation, fisher community livelihoods, and blue economy principles.
Rural Development
Pioneering participatory design methodologies that position rural communities as destination managers — connecting grassroots enterprise to national tourism policy and international certification schemes.
Climate Resilience
Modelling the vulnerability of tourism infrastructure and visitor patterns to climate change in island and coastal destinations, with adaptive policy recommendations for the SIDS and South Asian context.
Policy & Governance
As Resource Person for Sri Lanka's National Tourism Policy and ADB Tourism Education Expert, translating academic sustainability science into implementable regulatory frameworks across the Asia-Pacific.
Heritage × Sustainability
Quantifying the economic and social return-on-investment of heritage conservation investment, and designing tourism revenue mechanisms that fund ongoing cultural preservation in UNESCO-listed sites.
Guiding Framework
Visitor numbers must be scientifically constrained to the biological and social absorptive capacity of every destination. Growth beyond threshold is not success — it is asset destruction.
Tourism revenue must circulate within host communities before flowing outward. Leakage to multinational chains represents a structural failure of sustainable tourism economics.
Living cultures are not spectacles for visitor consumption. Tourism design must protect intangible heritage and ensure communities retain authority over how their traditions are shared.
Sustainability claims without rigorous baseline data and longitudinal monitoring are marketing, not governance. Every policy prescription must be grounded in verifiable impact evidence.
Women constitute the backbone of hospitality labour while holding marginal ownership stakes. Sustainable tourism governance must actively redress this structural inequity through policy and finance mechanisms.
Every tourism decision must be evaluated against its impact on the next generation's ability to enjoy the same natural and cultural assets. Present gain at future cost is an ethical failure, not a development strategy.

A Scholar's Commitment
"The most powerful intervention we can make for the planet is to prove that tourism, done well, makes conservation economically inevitable."
