Land Policies

Cattle and yaks in Bhutan are mainly managed in a transhumance system, grazing common pooled resources. This is, however, changing due mainly to policy changes and development pressure. The unequal land policies now restrict mobility for cattle-based transhumance by agro-pastoralists although it is expected to remain the same for the yak-based pastoralists. Essential public infrastructures also are being built in the common pooled resources, thus reducing the grazing areas for cattle and yaks alike. This study uses qualitative interview and focus group discussions in conjunction with administrative data and policy documents to understand the forces that increasingly lead to the decline of transhumance and see how it might change the grazing landscape and socialscape in the future. The study finds that grazing in the future will likely transform from an extensive to a semi-intensive system with smaller herd sizes for cattle-based agro-pastoralists. This is being achieved through interventions implemented by the livestock department, promoting crossbreeding with European dairy breeds. Transhumant herder turned sedentary smallholder farmers are fast adopting a sedentary lifestyle. This is changing not only the landscapes from grazing in large expanses of forest and open meadows to restricted semi-intensively managed smallholder farms with a possible impact on biodiversity. Crossbreds of European dairy cattle are fast replacing indigenous siri cattle of the Bos indicus type. Yak-based transhumance is expected to continue with favorable policies and other opportunities, including collection of the highly priced caterpillar fungus, Cordyceps sinensis. The socialscapes are fast changing for both highlanders as well as mid and lowland herders. Many of these places inhabited by herders are now connected by motorable roads, shortening their travel time to the nearest health facilities or shops from days to hours.

Abstract Ophiocordyceps sinensis (syn. Cordyceps sinensis) is a peculiar caterpillar fungus. It is not only known for its extraordinary medicinal values, which cover a wide spectrum of illnesses ranging from fatigue to cancer, but also for its fascinating life-story (Yeh & Lama 2013). Unlike many medicinal products, advertisements for “Cordyceps” do not solely promote its medicinal value, but also the origin of its production. Retailers often employ snowy mountains, Tibetan script, Tibetan people, blue sky and green meadows to advertise their products. Te imagined geography delivers a message to consumers that it is a natural wonder that comes from a Xanadu, a distant, exotic, untouched and unpolluted place. Te description of its production site is not meant to deceive the consumers, but it is only one piece of the story. Behind the veil of Ophiocordyceps commodification, we see missing pieces from a personal experience during a two-month-long field research in the eastern Tibetan region in summer 2018: Tibetan harvesters, a harsh climate, the declining Ophiocordyceps populations, plastic packaging and aluminum cans loitering the meadows. All these are also part of the production story.

This study comprises report on mycological exploration in 2006 at the most remote and highland district, Dolpa of Western Nepal. The study area was virgin for mushrooms study. Forty four species were collected, out of which 40 are new to the area. The collected species are parasitic, saprophytic and mycorrhizal associates' in habitat. Locally 22 and five species were used for culinary and medicinal values respectively. Cordyceps sinensis, Morchella conica, M. esculenta, Laetiporus sulphureus, Agaricus bisporus, Termitomyces clypeatus and Cantharellus cibarius are most popular and potential resources from the study sites.Key words: Caterpillar fungus; Dolpa; macrofungi; morels mushrooms; NepalJournal of Natural History Museum Vol. 23, 2008 Page 51-59

Antitumour Effects

Abstract Cordyceps sinensis, a species of the genus Ascomycetes, is recognised as the most famous tonic herb and natural remedy in traditional Chinese medicine for centuries. Various pharmacological actions of the chemical constituents of C. sinensis have been reported, including: antitumour effects, hepatoprotective and anti-inflammatory effects, and antioxidant, nephroprotective and anti-apoptotic properties. In this study we tested the antioxidant activity of extracts of the fungus C. sinensis grown on two subspecies of rice, Oryza sativa var. Indica and Oryza sativa var. Japonica. The extracts were prepared with methanol by two different extraction procedures (reflux and ultrasound). The antioxidant activity of the extracts was determined by the DPPH assay. Our investigations showed that the sample 1 (grown on Oryza sativa var. Japonica) exhibited higher antioxidant activity than the sample 2 (grown on Oryza sativa var. Indica). The higher antioxidant activity of the sample 1 was observed with both extraction procedures.

Prior Administration

The effect of prior administration of haematoporphyrin derivative on the uptake in tumours of 67Ga, 59Fe and 65Zn has been studied in tumour-bearing rats and mice. An approximately two-fold increase in the uptake of 67Ga was observed in the August 15 rat tumour when the nuclide was administered 17 to 24 hr after haematoporphyrin. No increase in the uptake of 67Ga occurred in three mouse tumours. Haematoporphyrin administration did not affect the uptake of 65Zn and 59Fe in any of the tumour systems. It is concluded that the presence of haematoporphyrin does not markedly increase the ability of tumours to accummulate metallic radionuclides.
