Nicodemus) Foreword The substantial socio-economic importance of casuarinas (several members of the family Casuarinaceae) has ensured ongoing international interest in research and development of this group of nitrogen fixing trees. Plantings are invariably associated with agricultural systems and there are more than two million hectares planted in the tropics and sub-tropics, offering stability to fragile sandy coastal ecosystems and offering services of protection, soil organic matter, poles, fuelwood and commercial wood fibre. Following the previous five international casuarina meetings, the most recent one in Chennai, India in 2014, Kasetsart University is pleased to host the Sixth International Casuarina Workshop in Krabi province, Thailand during 21-25 October 2019 in collaboration with the IUFRO Working Party–Improvement and Culture of Nitrogen Fixing Trees, and the IUFRO Taskforce–Forest Biomass Network. The theme of this sixth workshop, Casuarinas for Green Economy and Environmental Sustainability, reflects in the current relevance of casuarina trees in the world. A total of 79 participants from ten countries attended the Workshop and delivered 43 oral presentations under six sessions. Outputs from the Sixth International Casuarina Workshop are synthesized in these proceedings. I hope this publication is valuable for all stakeholders involved in casuarina research and development. Dr Chongrak Wachrinrat President Kasetsart University i Preface Extensive plantings of casuarinas have been developed throughout the tropics, including highlands, humid and semi-arid zones, by smallholders and Governments and increasingly by private forestry corporations. The continued successful development of casuarina forests and agroforests is dependent on research and development to provide improved and diverse germplasm, including for improved agroforestry systems, integrated pest and disease management, understanding of their tolerance to physiological stresses and climate change, and their wood properties including for pulpwood, in biorefineries and as biofuels. International meetings of casuarina scientists are vital to develop a strong network of researchers in order to share ideas, information, germplasm and new technologies. Previous and highly successful international casuarina meetings have been held in Canberra, Australia in 1981; Cairo, Egypt in 1990; Danang, Vietnam in 1996; Hainan, China in 2010 and Chennai, India in 2014. These proceedings report on the sixth international casuarina workshop held at Krabi, Thailand during 21-25 October 2019. In line with the theme of the Workshop, ‘Casuarinas for green economy and environmental sustainability’ the papers and discussions during the meeting were focused on assessing the impact of casuarina planting in meeting the industrial biomass raw material demand and improving edaphic and climatic conditions. In particular the additional benefits derived due to the research and development work carried out so far and increasing the accessibility of such new findings to all those involved in casuarina planting were reviewed. The workshop was supported by Kasetsart University and the International Union of Forest Research Organizations (IUFRO), with crucial organizational support provided by the Kasetsart Agricultural and Agro-Industrial Product Improvement Institute (KAPI). Key international partners were the CSIRO (Australia) and IRD (France), and key national partners in Thailand were the Department of Marine and Coastal Resources, Royal Forest Department, and Forest Industry Organization. Regional and international collaborations were proposed to share the expertise and germplasm from countries that have already made substantial genetic and economic gains through long-term research programmes with those that are beginning or in early stages of improving the species. Strategies for conservation of available genetic resources in the natural range and broadening of the genetic base and overcoming the biotic and climate change induced threats in the cultivated stands were proposed for long term securing of casuarina utilization.
