In Vivo Screening of Salinity Tolerance in Giant Swamp Taro (Cyrtosperma Merkusii)
CSIRO PUBLISHING The South Pacific Journal of Natural and Applied Sciences, 32, 33-36, 2014 www.publish.csiro.au/journals/spjnas 10.1071/SP14005 In vivo screening of salinity tolerance in Giant Swamp Taro (Cyrtosperma merkusii) Shiwangni Rao1, Mary Taylor2 and Anjeela Jokhan1 1Faculty of Science, Technology & Environment, The University of the South Pacific, Suva, Fiji. 2Centre for Pacific Crops & Trees, Secretariat of the Pacific Community, Suva, Fiji. Abstract Giant Swamp Taro (Cyrtosperma merkusii) is a staple food crop in the Pacific, especially in the low lying atoll islands such as Tuvalu and Kiribati. This is owing to its ability to survive under poor soil conditions and harsh environments. However, as a result of the effects of climate change such as sea water inundation and intrusion into the fresh ground water lens, this crop is now under threat. To address this issue an adaption approach was taken whereby, Cyrtosperma merkusii was screened in vivo for salt tolerance. The epistemology followed random selection of two cultivars Ikaraoi and Katutu. These two cultivars were subjected to 0% (0 parts per trillion), 0.5% (5 ppt), 1% (10 ppt), 1.5% (15 ppt) and 2% (20 ppt) of salt in Yates’s advance seedling common potting mix. Both cultivars were able to tolerate salinity levels up-to 5ppt which is significantly more than the salt tolerance in glycophytes of 2.83 ppt. This research provides an insight into the variation of salt tolerance that may exist in C.merkusii gene pool, which can be used to adapt to natural disasters and buffer its impacts. -

Nutritious Leafy Vegetables to Improve Nutrition Security on Pacific Atolls
FACTSHEET NUTRITIOUS NO: LEAFY VEGETABLES FOR ATOLLS 01 Tackling NCDs from the ground up: Nutritious leafy vegetables to improve nutrition security on Pacific atolls Introduction Epidemic of non-communicable diseases (NCDs) Since the 1940s the consumption of high-energy, low-nutrient foods, including white flour, sugar, polished rice, turkey tails and mutton rib flaps by Pacific Islanders and indigenous Australians, combined with reduced exercise, has resulted in alarming rates of obesity, heart disease, diabetes and certain cancers. Indeed, around 70% of deaths in Pacific Island countries (PICs) are due to NCDs. Apart from the tragic personal cost, premature death and disability undermines national economic productivity. These conditions were not present when traditional diets and lifestyles predominated. In addition, many PICs are affected by the “double burden” of NCDs and undernutrition; for example, high rates of iron deficiency anaemia in PNG, Fiji, Solomon Islands and Tuvalu. This project, funded by the Australian Centre for International Agricultural Research (ACIAR) and titled Improving soil health, agricultural productivity and food security on atolls (ACIAR SMCN2014/089) builds on the project Feasibility study on increasing the consumption of nutritionally-rich leafy vegetables by indigenous communities in Samoa, Solomon Islands and Northern Australia (ACIAR PC/2010/063): www.aciar.gov.au/publication/fr2014-15 The project included a GxE study in which single leafy vegetable species were sampled across different sites/different soils and multiple species growing at the same site were sampled, then analysed for mineral nutrients and carotenoids, including beta-carotene (pro-vitamin A). This approach enabled partitioning of the effects of environment (mostly soil type) and genetics (plant species). -

Root and Tuber Crops of the Pacific: a Resource for Meeting the Challenges of the 21St Century
Root and tuber crops of the Pacific: A resource for meeting the challenges of the 21st century Mary Taylor1, Valerie Tuia1, Rosa Kambuou2 and Tevita Kete1 Secretariat of the Pacific Community, Private Mail Bag, Suva, Fiji1 [email protected]; National Agriculture Research Institute, Papua New Guinea2 Abstract The Pacific Island Countries and Territories, home to an estimated 9.5 million people, are geographically, ecologically, sociologically and economically diverse. This region faces numerous social and physical challenges simply by nature of the size of the islands, and their geographical isolation. The 21st century, however, has brought new challenges from climate change to increasing food prices to the alarming increase in lifestyle- related diseases, which is strongly associated with the over-consumption of nutritionally poor foods, often imported. The response to the increasing food prices has been to strengthen local food production. Increasing local food production and promoting local food consumption provides an excellent opportunity to address the nutrition-related health problems. However, local food production has to be sustained in the light of climate change. This paper describes the work of the Secretariat of the Pacific Community (SPC) in promoting and supporting the conservation and utilization of root and tuber diversity, as one of the solutions to manage these many challenges. For example, the SPC Centre for Pacific Crops and Trees (CePaCT), which houses a unique collection of over 850 accessions of taro (Colocasia esculenta), as well as other crops and trees of importance to the region, is building a “climate-ready” collection, consisting of local crops and varieties selected because such diversity will provide the farmers in this region with the traits, such as drought and salt tolerance. -

Water is obtained directly from rivers, lakes, and other watercourses. At present, Papua New Guinea is undergoing rapid economic growth in forestry, agroforestry, mining, and petroleum development activities. Most (if not all) of these natural resources development activities are conducted on customary land and in and around the environment in which the majority of the indigenous peoples live and on which they rely for their subsistence way of life. -

Only 2% of this area is land, of course, but this is home to about 8 million people, speaking 50% of the world's languages, over 800 in PNG alone. Most of these people live in rural areas and rely on agriculture, together with fishing and forest products, for their livelihoods. The Pacific is a centre of diversity and/or origin for a small cumber of crops, but in general, due to its history of human colonization, crop genetic diversity in the mostly vegetatively propagated crops of the region declines markedly from west to east. -

Observation and sociolinguistic interviews were used to investigate language vitality and speakers’ attitudes toward neighbouring languages. Additionally, interviews with community leadership were used to investigate interest in language development It was found that the Abadi language is currently vital, although indicators suggest that vitality may decrease in coming years. Abadi speakers hold a positive attitude toward their language and community leaders are interested in language development. 2 Contents Abstract 1. Introduction 2.
