Digital Technology for Preserving Cultural Heritage in Tonga
Part 2: ICT4D for the Indigenous, by the Indigenous and of the IndigenousInternational audienceCultural heritage embodies and carries the stories and values of our ancestors that define our understanding of who we are today. A societyâs heritage serves an important purpose for educating people about their own culture and aiding in understanding their traditional values. In Tonga, where this research has been conducted, the historical knowledge and cultural values have been usually transferred orally from generation to generation. However, due to the pressures of globalisation, westernisation and migration, cultural heritage is under threat. These threats can potentially impede the transferring of societiesâ idiosyncratic identity to future generations and erode cultural life. ICT as an option to preserve cultural heritage offers opportunities to not only capture and immortalise tangible and intangible cultural artefacts but also enables the accessibility of those artefacts to a wider audience through the internet. It is against this background that we explore how digital technologies are utilised in the process of preserving cultural heritage

Genetic and Genomic Approaches for Adaptation of Grapevine to Climate Change
The necessity to adapt to climate change is even stronger for grapevine than for other crops, because grape berry compositionâa key determinant of fruit and wine quality, typicity and market valueâ highly depends on âterroirâ (complete natural environment), on vintage (annual climate variability), and on their interactions. In the same time, there is a strong demand to reduce the use of pesticides. Thus, the equation that breeders and grape growers must solve has three entries that cannot be dissociated: adaptation to climate change, reduction of pesticides, and maintenance of wine typicity. Although vineyard management may cope to some extent to the shortâmedium-term effects of climate change, genetic improvement is necessary to provide long-term sustainable solutions to these problems. Most vineyards over the world are planted using vines that harbor two grafted plantsâ genomes. Although this makes the range of interactions (scion-atmosphere, rootstock-soil, scion-rootstock) more complex, it also opens up wider possibilities for the genetic improvement of either or both the grafted genotypes. Positive aspects related to grapevine breeding are as follows: (a) a wide genetic diversity of rootstocks and scions that has not been thoroughly explored yet; (b) progress in sequencing technologies that allows high-throughput sequencing of entire genomes, faster mapping of targeted traits and easier determination of genetic relationships; (c) progress in new breeding technologies that potentially permit precise modifications on resident genes; (d) automation of phenotyping that allows faster and more complete monitoring of many traits on relatively large plant populations; (e) functional characterization of an increasing number of genes involved in the control of development, berry metabolism, disease resistance, and adaptation to environment. Difficulties involve: (a) the perennial nature and the large size of the plant that makes field testing long and demanding in manpower; (b) the low efficiency of transformation, regeneration and small size of breeding populations; (c) the complexity of the adaptive traits and the need to define more clearly future ideotypes; (d) the lack of shared and integrative platforms allowing a complete appraisal of the genotype-phenotype-environmental links; (e) legal, market and consumer acceptance of new genotypes. The present chapter provides an overview of suitable strategies and challenges linked to the adaptation of viticulture to a changing environment
