The presence of wild edible plants and determinants influencing their harvest, consumption, and conservation in south eastern Bhutan.

DEFINITION: Wild edible plants (WEPs) grow naturally in self-maintaining ecosystems. WEPs are harvested for consumption, sale, and medicinal uses. We hypothesize that WEPs play a major role in supplying food and generating income for the rural people in a world that is increasingly recognising its emerging conservation issues. We tested this hypothesis by identifying the reasons for harvest, consumption, and conservation of WEPs using focus group discussion, field observations and questionnaire surveys in south eastern Bhutan in late 2019. METHODS: Focused group discussions were held with the local people to identify reasons for harvest and consumption of WEPs. Data on the identified reasons for harvest, consumption, and conserving WEPs were determined using a questionnaire survey with ranking scales for a set of 76 randomly selected households. Representative field-observations and questionnaire surveys were carried out in villages close to forests. Parts of the plant used, how these were consumed, harvest season, and plant (life form) were recorded. The data was subjected to a Kruskal-Wallis rank sum test and weighted averages calculated. RESULT AND CONCLUSION: A total of 120 WEPs belonging to 63 families (including Agaricaceae) were reported. Most of the WEPs recorded were trees (45.0%) then herbs (25.8%), vines (13.3%) and shrubs (10.8%). The commonly consumed plant parts were the fruit (43.3%), shoots (28.3%) and leaves (20.8%). The purposes for harvesting and consumption, conservation of WEPs were significantly (P<0.001) different, while the motivations for collecting WEPs were not. The motivation for collecting WEPs were family consumption > sale > medicinal uses > preservation for future use > insufficient food from cultivated source's. The two most important strategies for conservation were to domesticate the WEPs and cultivate in forests. The findings reveal valuable lessons and insights about the reasons for harvesting, collection, consumption, and conservation of WEPs.

Determinants Influencing Selection of Potato Varietal Technology and the Role of Gender in Farm Decisions in Bhutan.

Potato is a primary food and cash crop in Bhutan. The adoption of new varieties has faced some challenges. To address this situation, farmers' needs and priorities were investigated through varietal demonstration and a field survey in seven of the main potato-growing districts of Bhutan. The role of gender in farm decisions and operations in relation to potato farming was also assessed. Nine quality determinants significantly (χ 2 = 376.54, P < 0.001) influenced farmers' selection of potato varieties. These determinants, in order of their relative preference, were as follows: high productivity (15.5% by weight of mean rank), high market value (13.4%), red-skinned (12.7%), marketability (11.6%), large tubers (11.3%), late-blight resistant (11.3%), micronutrient content (8.8%), short-duration (8.3%) and good taste (7.2%). Potato productivity (yield) and preference vote data were significantly correlated (R = 0.395, P < 0.01) for female farmers but not for male farmers. Similarly, the involvement of female farmers in farm decision-making processes was significantly (P < 0.001) higher than when compared with their male counterparts. However, both genders were equally involved in physical farm operations. Bhutanese potato cropping is highly driven by commercially driven (market) preferences such as yield, colour and size as opposed to subsistence preferences such as micronutrient content. Understanding farmers' priorities during the development of new potato variety is critical for varietal selection for adoption. Furthermore, understanding the role of women in farm decision-making processes is crucial for adoption of new varietal technology in potato production. These findings may serve as an evidence-based insight to guide research and policy interventions in Bhutan and in similar agroecologies.
