Snake Gourds, Parasites and Mother Roasting : Medicinal plants, plant repellents, and Trichosanthes (Cucurbitaceae) in Lao PDR
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background. Traditional plant use was studied in Lao PDR. Research focused on medicinal plant use by the Brou, Saek and Kry ethnic groups, traditional plant repellents against parasitic arthropods and leeches, and the phylogeny and biogeography of the medicinally-important snake gourd genus (Trichosanthes, Cucurbitaceae). Methods. The ethnobiology research used a combination of structured interviews, village surveys, botanical collecting, hydro-distillation, GC-MS analysis, literature studies, and laboratory experiments. The plant systematics research used a combination of morphological studies, molecular biology laboratory work, and phylogenetic, dating and biogeographical analysis. Results. Informants reported the use of close to 100 species to repel arthropods and leeches, many of which have constituents with documented efficacy. Brou, Saek and Kry informants use over 75 plant species for women’s healthcare, mainly during the postpartum period for steam sauna, steam bath, hotbed, mother roasting, medicinal decoctions and infusions, and postpartum diet. A molecular phylogeny of Trichosanthes and Gymnopetalum using a broad sampling of ~60% of their species and 4756 nucleotides of nuclear and plastid DNA shows that Gymnopetalum is nested within Trichosanthes. Fossil-calibrated Bayesian molecular dating of the Trichosanthes phylogeny reveals an early Oligocene origin of the genus, and many of the extant sections originating and diversifying during the Miocene. Biogeographical analysis shows a likely East or South Asian origin of Trichosanthes, with lineages diversifying and spreading throughout Australasia from the early Pliocene to the Pleistocene. Discussion. Traditional plant use in Lao PDR is common and widespread. The presence among the repellent species of economical alternatives to costly synthetic repellents is tenable, and the subject of ongoing studies. Postpartum traditions and medicinal plant use are essential parts of childbirth and postpartum recovery in these ethnic groups, and many other groups in Lao PDR. Efforts to improve maternal healthcare and reduce maternal and infant mortality need to integrate these traditions with modern notions of healthcare to achieve wider adoption. Documenting all possible uses of commonly used medicinal plant species shows that similarity in use between these ethnic groups is relatively low considering that they share, and have shared for many generations, the same environment and resources. A lack of effective cures leads to a process of continuous innovation, where effective cures are shared between cultures, but remedies of only cultural importance, or those under evaluation are culture-specific. The Trichosanthes phylogeny implies the merging of Gymnopetalum into Trichosanthes, and this is done using available names or new combinations. A synopsis of Trichosanthes, the new combinations, and a revision of the species in Australia, are made and presented. Conclusions. Traditional plant use is widespread in Lao PDR, and of significance to many people as a source of primary healthcare and inexpensive repellents. The important medicinal plant genus Trichosanthes includes Gymnopetalum, and has a complex biogeographic history with multiple colonization events of Australasia.

Bokkapitel (refereegranskat)abstract
- Over recent decades, Indigenous knowledge (IK) systems, people, and territories have increasingly been recognized in mainstream conservation practice. However, recognition of the value of IK by governing bodies varies and is often a result of colonial and “development” history and the strength of hegemonic attitudes. Through regional case studies, this chapter explores the progress and challenges of integrating IK in conservation action which is key to narrowing the knowledge-implementation gap in this discipline. Key enabling factors allow IK integration into conservation action at national levels including: recognition of Indigenous land ownership; development and acceptance of cross-cultural or Indigenous methods; devolution of power to include Indigenous People in decision-making processes; acknowledgment of Indigenous groups and their rights; and acknowledgment of the benefits of using IK in biodiversity conservation. The regional case studies presented in this chapter suggest that the recognition of IK systems in conservation programs is greatly facilitated by adopting three pillars of Indigenous empowerment (Indigenous land ownership, acknowledgment of Indigenous peoples and their rights, and acknowledgment of the value of Indigenous knowledge systems) with concomitant benefit to narrow the knowledge-implementation gap in conservation science.

Traditional ecological knowledge and community resilience to environmental extremes : a case study in Donana, SW Spain

Tidskriftsartikel (refereegranskat)abstract
- Research in the last decade has emphasised the potential contribution of traditional ecological knowledge to cope with challenges from global environmental change. This research examines the role of traditional ecological knowledge and shared systems of beliefs in building long-term social-ecological resilience to environmental extremes. Data were collected from 13 villages of the Donana region, southwestern Spain, through interviews, focus groups, and systematic reviews of historical archives. First, we assess adaptive practices to cope with environmental change. Then, we use historical records of religious ceremonies (1577-1956) to reconstruct collective responses to environmental extremes. Our results (1) show how environmental extremes could induce social and economic crises through declines in ecosystem services and (2) identify practices to cope with recurrent disturbance and institutional devices developed in response to environmental extremes. We conclude that traditional ecological knowledge and shared systems of beliefs can facilitate collective responses to crises and contribute to the maintenance of long-term resilience of social-ecological systems.

Tidskriftsartikel (refereegranskat)abstract
- Mainstream discourses frame anthropogenic climate change as a biophysical apolitical problem, thus privileging Western science and silencing other worldviews. Through a case study among the Bassari, an ethnic group in South-Eastern Senegal, we assess the local, embodied, and situated understandings of climate change and the tensions that arise when the apolitical global climate change discourse interacts with situated understandings. Drawing on data from 47 semi-structured interviews and 176 surveys, we find that while the global climate change discourse has not permeated into the Bassari, they experience climate change through its many impacts on the biophysical and socio-economic systems. Results also highlight that climate is not considered the main or only driver of change, but that changes in elements of the climate system are inextricably linked with political and economic dynamics and environmental degradation. Finally, our results point toward the importance of values and supernatural forces in defining situated ways of conceptualizing, interpreting, and responding to change. By including situated worldviews in theoretical understandings of climate and environmental change, we contribute to the claims about the need to reframe how climate change is conceptualized. Our research emphasizes the importance of a relational view of climate change, which requires moving beyond understanding isolated climate change impacts towards defining climate change as a systemic problem. Building on feminist and decolonial literature, we argue for the need for more plural and democratic ways of thinking about climate change, crossing epistemological and ontological boundaries and including local communities and their knowledge and understandings.
