• Colonial Narratives and the Ruined Cities of Ceylon: Exploring the Earliest Architectural and Archaeological Documentation during the Colonial Period

  Colonial-era documentation efforts under British rule (1806–1948) laid the foundation for modern architectural and archaeological study of Sri Lanka’s ancient cities, including Polonnaruwa, Anuradhapura, and Sigiriya. These ruins, rediscovered in the mid-19th century by colonial administrators and professionals, were systematically recorded through archival, cartographical, and iconographical research. This systematic approach culminated in the establishment of the Archaeological Survey of Ceylon, shaping the preservation and recognition of these sites as UNESCO World Heritage Sites.

• An Investigative Study of the Theories Surrounding the Standing Buddha Statue at the Polonnaruwa Rock Temple

  The standing Buddha statue at Polonnaruwa Rock Temple, Sri Lanka, embodies multiple symbolic interpretations rooted in Buddhist iconography. Research reveals that the statue's unique mudra—variously identified as Paradukkha Dukkhitha, Animisa Lochana, Swastika, or Avadhana—represents pivotal moments in Buddha's life, including the second week of his enlightenment and the Great Passing Away (Parinirvana). Additionally, its posture suggests a compassionate gaze toward beings, while theories propose it may depict Ananda Thero. The study analyzes these interpretations through secondary sources, leveraging Buddhist literature to explore their historical and symbolic significance. This approach highlights the statue's cultural and religious importance during the Polonnaruwa period (post-Anuradhapura), cementing its status as a peak in Sri Lankan Buddha statue art.

• Feasibility study of micro-scale wind power generation for rural electrification in Polonnaruwa area

  A feasibility study of micro-scale wind power generation for rural electrification in the Polonnaruwa area reveals that installing a 500 W turbine at a 10-meter hub height is optimal, offering superior annual energy production, capacity factor, and carbon savings. The research analyzed wind speed data from two years (2019–2020) using Weibull probability distribution to assess the region's wind power potential. Findings indicate that micro-scale turbines with low cut-in wind speeds (2 m/s) are highly suitable for standalone power generation in this UNESCO World Heritage Site, addressing both energy demand and environmental concerns while avoiding reliance on fossil fuels.

• Human-elephant conflict: challenges in agriculture Sector in Polonnaruwa district; A study based on literature review

  Human-elephant conflict in the Polonnaruwa district, Sri Lanka, poses significant threats to both elephants and agricultural sectors. The study reveals that such conflicts are a major socio-environmental issue, with 42% of incidents occurring in high-risk areas like the North Central Province. Key challenges include crop damage, property destruction, human fatalities, and elephant deaths, often exacerbated by inadequate compensation methods and limited local mitigation strategies. The research highlights the ineffectiveness of current measures such as bio-fences and electric fences while emphasizing the need for inter-cooperation to minimize conflicts. Through a systematic literature review, the study identifies gaps in conflict resolution and calls for methodological improvements to address these pressing issues.

• Shields on Electric Posts Prevent Primate Deaths: A Case Study at Polonnaruwa, Sri Lanka

  A case study at the UNESCO World Heritage Site of Polonnaruwa, Sri Lanka, demonstrates that shields mounted on electrical posts significantly reduced electrocution deaths among toque macaques (Macaca sinica). Over a 12-year period post-installation, no electrocutions were recorded, compared to 18 incidents in the preceding 12 years. The study highlights the effectiveness of simple interventions like shields and insulated PVC pipes in mitigating risks for primates and other arboreal mammals near human habitats. While not all electrocution hotspots could be addressed, the findings suggest broader applications for such measures in power distribution planning to protect wildlife.
