    Assessment of Parabolic Solar Cooker as Alternative Cooking Fuel and Users’ Perception towards it in Beldangi Refugee Camp, Damak
    (Faculty of Environmental Science, 2016) Nepal, Khyam Raj
    This study was carried out to assess the effectiveness of Solar Cooker (SK-14) in Beldangi Refugee camp, Damak, Nepal and its contribution towards the sustainability. A questionnaire survey in user’s household was conducted to assess the user’s attitudes and field sample survey was conducted for the assessment of the saved amount of biomass and fuel related CO2emission compare to baseline cooking technology. Solar cooker has been used for cooking purpose along with solid biomass as briquette coal and fuel wood. According to the survey data the average numbers of hours using solar cooker is about 4 hour (3.95) per day,663 hrs in a year as average number of days using solar cooker is 46 days in per 100 days. Among these facts 74 % of respondent’s family uses daily, 22% respondent’s family uses occasionally and rest 4% are not using due to partial damage or lack of space. The user’s expressed their satisfactions regarding the operation of SK-14, found to have 11% excellent, 55% goods, 17% satisfactory, 11% poor and 6% very poor performance. The amount of heat energy contributed by the SK- 14 throughout the year is 1068.1 MJ for the cooking (average 663 hrs as effective operating hours in a year) with average power of 430watt. Again the amount of CO2 emission reduction by one solar cooker in one year is found to be 3.906 tons if baseline cooking technology is traditional cook, which is equivalent to 1065.95 kg of fuelwood. Similarly, the amount of CO2 emission reduction when improved cook stove is found to be 1.953 tons per year per solar cooker and this is equivalent to 532.75kg of fuel wood.

    Ethnobotanical Study of Muchu Vdc in Humla District
    (Faculty of Environmental Science, 2012) Prajapati, Meena
    Humla is one of the remote mountainous districts situated in the northwest corner of Nepal bordering with China. The main objective of research is to assess the ethnobotanical study of Muchu VDC and to know the similarity of ethnobotanical and conservation knowledge of different age people. Research was carried out in 9 wards of Muchu VDC Humla. Data collection with other required information was collected on June 2010. Semi structured questionnaire was conducted randomly in Muchu VDC. Likewise, the questionnaire survey was supplemented with the interviews, group discussions, different informal interaction, and direct field observation. The data of consensus analysis were analyzed through PAST software. This study documented the traditional ethnobotanical knowledge of Lama Community of upper Humla. The study could identified and documented 148 species of plants, out of which 17% are cultivated in the fields, 72% are available in nearby forest and lekh and remaining 11 % are found both in wild and cultivated form. Among them maximum 71% of plants are herbs and least 1% of them are Creeper. In lama community there have a wide range of knowledge on the use of plants for various purposes here 69% plants are reported to be of single use, 23% with double use and 8% with triple use. Especially old age people have very good knowledge of plant species and their uses. This is one of the best technologies in such remote area where there are no facilities of healthcare center. However, the consensus analysis shows no agreement of ethnobotanical and conservation knowledge of different age people. It is possibly due to the attraction of new generation towards allopathic medicine, commercialization of medicinal herbs and influences of modernization cause the traditional ethnobotanical knowledge diminishing slowly. Therefore, the traditional ethnobotanical knowledge should be preserved, promoted and disseminated.

    Population and Ecology of Sarus Crane (Grus antigone, Linnaeus 1758) in Northern Region of Rupandehi District
    (Faculty of Environmental Science, 2015) Gyawali, Bigya
    The present study was carried out on Sarus Crane (Grus antigone antigone) to estimate population of Sarus crane in the Northern region of Rupandehi district, to know breeding success and nest ecology of Sarus in the study area. This survey was carried out in August to October, 2013.Village road was taken as transect. Field observation and informal discussion was conducted to assess population status to know breeding success and assess nest ecology. Nests were visited and measured with a tape without disturbing eggs. Survey was carried out in 18 VDCs. 95 individuals of Sarus crane were found among which 29 were breeding pairs, 11 were observed in flock and 3 as single individuals and 23 were juveniles. Mean encounter rate of the Sarus was about 9 individuals per 7 sq. km. The maximum flock size was 11 individuals. Hatching success rate was 63.88 chicks per 100 laid eggs and 127.77 individuals per 100 nests. Among the active nests monitored, at least one egg was found in 18 out of 19 nests. So nesting success was 94.73 %. Among the 19 nests, 42.10 % were observed in wetland and 5.26 % in agricultural land and 52.6 % were in the interface of wetland and agricultural land. Average area of nest was 2.76 m 2 (n=19).
