Ongoing Research and Projects

Participation of University of Peradeniya in Technical Training of Erasmus + CBHE project UN4DRR at Maldives National University.

. Technical Training and Monitoring Meeting at Maldives National University, 29 Jan 2023 - 2 Feb 2023

Participated for UN4DRR Technical Training and Curriculum Development Evaluation Workshop

2 May – 6 May, 2023 Vrije Universiteit Brussel Brussels, Belgium.

University Network for Disaster Risk Reduction in Indian Ocean Rim (UN4DRR) Project ERASMUS+: Capacity Building in Higher Education (CBHE) Postgraduate Institute of Humanities and Social Sciences (PGIHS), University of Peradeniya

The overall aim of the UN4DRR project is to modernize the courses related to Disaster Risk Reduction and Management (DRRM) integrating Geographic Information Systems (GIS) / Remote Sensing (RS) applications as a significant part of the course content. The long-term effect will be to educate future experts for prevention and management of natural and human-induced disasters in the Indian Ocean Rim supporting national and EU policies. The project encourages cooperation with national authorities, the public and private sector offering joint DRRM initiatives, and access to short courses for use of GIS/RS via online/offline mode. The project also motivates a more proactive cross-regional dialogue in DRRM related educational programs in the realization of capacity building and internationalization. The project which is funded by the EU is coordinated by the Vrije Universiteit Brussels, Belgium. The consortium has 8 other partner Universities; 3 from Europe (Polytechnic University of Valencia, Spain; University of Nicosia, Cyprus; University of Zagreb, Croatia), 5 from Asia (University of Peradeniya; University of Colombo; The Maldives National University; IPB University, Indonesia; University of Syiah Kuala, Indonesia). The project partnership of the University of Peradeniya is carried out through the PGIHS and coordinated by Professor Rekha Nianthi, Department of Geography. The partnership with the project was initiated by Professor Rekha Nianthi through her association with the Erasmus Mundus EXPERTS-SUSTAIN programme. Under the project, she developed a new study programme on disaster risk reduction and GIS+RS. The programme will be introduced with innovative teaching/learning methodologies in DRRM and GIS/Remote sensing techniques. A team of staff members from the Department of Geography (Prof. Rekha Nianthi, Dr. Kumuduni Kumarihamy, Dr. S.I.S. Subasinghe, Mr. Ashvin Wickramasooriya, Ms. B. Arularasi, and Dr. Pushpika Masakorala) is in the process of developing an Advanced Certificate/Diploma in Geospatial Technologies for Disaster Risk Reduction. It is also expected to reach out to public/private groups through joint DRRM initiatives and access to distance courses (online/offline) and to establish links between national authorities responsible for DRRM and academic institutions. The team members of the Erasmus+ CBHE project, University Network for Disaster Risk Reduction in Indian Ocean Rim (UN4DRR) visited the University of Peradeniya on 17 December 2021 during the Capacity Building Training Workshops for Researchers of the project at the University of Colombo and the University of Peradeniya. Another purpose of the visit was to follow up on project implementation activities and raise project awareness with University administrators. The delegates met the Vice-Chancellor, Prof. M. D. Lamawansa, and the Director/PGIHS, Prof. Suresh De Mel during the visit.
