The rapid and extensive loss of biodiversity globally has resulted in an increased urgency to capture and conserve the diversity which is present, including genetic diversity within species. However, for many species there is currently no detailed genetic data available to inform the collection and use of material held in ex situ collections and this can hamper the consideration of genetic issues and reduce the likelihood collection represent the diversity present. Even in the absence of direct genetic data, however, it is possible to consider genetic issues using the existing theoretical and empirical evidence-based and biological, ecological and demographic data for a given species. Here a framework to facilitate the consideration of genetic diversity and genetic issues, even where genetic data is lacking, is presented.

AbstractConservation practices during the first decade of the millennium predominantly focused on resisting changes and maintaining historical or current conditions, but ever-increasing impacts from climate change have highlighted the need for transformative action. However, little empirical evidence exists on what kinds of conservation actions aimed specifically at climate change adaptation are being implemented in practice, let alone how transformative these actions are. In response, we propose and trial a novel typology—the R–R–T scale, which improves on existing concepts of Resistance, Resilience, and Transformation—that enables the practical application of contested terms and the empirical assessment of whether and to what extent a shift toward transformative action is occurring. When applying the R–R–T scale to a case study of 104 adaptation projects funded since 2011, we find a trend towards transformation that varies across ecosystems. Our results reveal that perceptions about the acceptance of novel interventions in principle are beginning to be expressed in practice.

AbstractConservation programmes are always limited by available resources. Careful planning is therefore required to increase the efficiency of conservation and gap analysis can be used for this purpose. This method was used to assess the representativeness of current ex situ and in situ conservation actions of 234 priority crop wild relatives (CWR) in Indonesia. This analysis also included species distribution modelling, the creation of an ecogeographical land characterization map, and a complementarity analysis to identify priorities area for in situ conservation and for further collecting of ex situ conservation programmes. The results show that both current ex situ and in situ conservation actions are insufficient. Sixty-six percent of priority CWRs have no recorded ex situ collections. Eighty CWRs with ex situ collections are still under-represented in the national genebanks and 65 CWRs have no presence records within the existing protected area network although 60 are predicted to exist in several protected areas according to their potential distribution models. The complementarity analysis shows that a minimum of 61 complementary grid areas (complementary based on grid cells) are required to conserve all priority taxa and 40 complementary protected areas (complementary based on existing protected areas) are required to conserve those with known populations within the existing in situ protected area network. The top ten of complementary protected areas are proposed as the initial areas for the development of CWR genetic reserves network in Indonesia. It is recommended to enhanced coordination between ex situ and in situ conservation stakeholders for sustaining the long term conservation of CWR in Indonesia. Implementation of the research recommendations will provide for the first time an effective conservation planning of Indonesia’s CWR diversity and will significantly enhance the country’s food and nutritional security.

Abstract Background: Fig trees are ecological keystone species in many tropical regions and play important roles in the spirituality, nutrition and health for many rural communities. Although the tropical forests in Myanmar contain many fig species, little ethnobotanical knowledge on their uses has been recorded.Information about the uses and conservation related actions of figswould be helpful in development ofstrategic policy for sustainable use and biodiversity conservation of the country. We showcase the rich ethnobotanical knowledge as well as the variety of collection and conservation practices related to figs among five ethnic groups in Southern Shan State. Methods: We performed both key informant and semi-structured interviews with 114 informants from five ethnic groups. Their uses for figs were categorized according to local practices and recipes. Informants were asked about trends in conservation status over the past 10 years and any conservation related customs and practices. Data were analyzed quantitatively by use report (UR) and use value (UV). Results: Informants reported the uses of eight fig species (Ficusauricularta，F.concinna, F. geniculata，F. hispida, F. racemosa, F. religiosa，F. semicordata, and F. virens).F. geniculata and F. virens were most useful (UR = 228) and were used by all five ethnic groups, corresponding to a high use value (UV = 2). Treatments for 16 diseases were reported from seven species. Household consumption, economic, and sacred uses were accompanied by sustainable practices of harvest and protection. Traditional taboos, in situ and ex situ conservation were practiced especially for highly demanded species (F. geniculata and F. virens), and the sacred fig F. religiosa.Conclusion: Findings suggest that figs are useful for nutrition (all informants) and medicine (13.16% of the informants) in the study area. Traditional taboos, in situ and ex situ conservation practices help to maintain sustainable utilization of locally important figs. This is an early contribution to the traditional knowledge of edible figs. Although similar uses have been reported in neighboring countries for seven of the fig species, the ethnobotanical use of F. concinna is novel.

The Impact

This chapter reviews the key issues and challenges facing genebanks in preserving crop genetic diversity ex situ. Local crop genetic diversity is challenged with changes in land use, urbanization, land degradation, changes in agricultural practises, availability of improved varieties, changes in market preference, and the impact of climate change. Efforts have been made to secure plant genetic resources ex situ for future use but there are significant issues related to cost effective, efficient, secure, rational, and sustainable long-term ex situ conservation. It begins by addressing issues for the composition of ex situ collections and moves on to discuss issues for routine operations for conservation. The chapter also highlights issues for the use of conserved genetic resources, before concluding with a summary of why the development of sustainable genebank systems is so important.

Abstract The study analysed the conservation gaps of the priority crop wild relatives (CWR) taxa for Malawi in order to contribute to the development of a harmonized conservation strategy that helps secure the priority CWR under in situ and ex situ. We used taxa distribution modelling, complementarity analysis and ecogeographic land characterization map to analyse spatial diversity and distribution of 123 priority taxa across different adaptive scenarios. We identified areas of observed and predicted richness, the minimum number of protected areas (PAs) that conserve the broadest ecogeographic diversity in situ and the minimum number of grid cells that capture highest diversity outside PAs to recommend the establishment of genetic reserves. We then analysed the representativeness of the conserved ecogeographic diversity of target taxa in ex situ collections to identify ex situ conservation gaps and advise for priority areas for ex situ collections. For the 123 taxa, 70.7% of the total diversity occurs in 36 PAs with 66.8% of the diversity captured in only 10 complementary PAs. Outside PAs, the broadest diversity was conserved in three grid cells of size 5 × 5 km. Fifty-three of 123 taxa have ex situ collections with only three taxa having ex situ collections at the Malawi Plant Genetic Resources Centre. The findings of this study will guide formulation of conservation actions for the priority taxa as well as lobbying for active conservation of the same under in situ and ex situ.
