Allometric equations for estimating timber volume of Populus deltoides in plantation trial of Populus deltoides were developed. Direct measurement of 60 trees in western Nepal was done for this purpose. Six models were tested with simple linear regression analysis technique. The best fit equation for volume was quadratic (0.1500 - 0.0205DBH + 0.00105*DBH2) with diameter at breast height as an...
The study on ‘effects of pre-sowing treatments on germination of Sapindus mukorossi Gaertn,’ was carried out in Jhanjhatpur nursery, Kailali district in April 2004. About 15-months old healthy seeds were treated in one of thirty ways before sowing and sown from 1 to 7 April 2004 in drills in a nursery bed at a spacing of 5 cm x 10 cm. The analysis revealed that thirty pre-...
A long-term growth monitoring experiment on Uttis (Alnus nepalensis) was conducted in the permanent sample plots of the Agricultural Research Station (ARS) Pakhribas, Dhankuta for 10 years (1992-2001). The average annual increment in diameter at breast height was 2.14 cm in the 8th year, and was 0.13 cm in the 16th year of planting. The trees grew 44 cm to 130 cm per year irrespective of the...
The Xylarium is mainly intended to display the wood collections for scientific research, teaching, environmental education and other xylarium programmes. This activity is useful for forest utilisation research and education. Nevertheless, it is not a new activity of the Department because wood samples of some 32 species are already existed in the library. Most of these species are of lowland...
Biodiversity is an important consideration in maintaining natural environmental balance in a particular habitat. This becomes particularly important in areas, where due to the encroachment of natural forests, biodiversity is depleting causing a potential loss in the natural habitat. In such a situation, biodiversity in the farmland becomes an important consideration. Biodiversity is measured...
There are growing concerns about the impact melting glaciers in the Himalayas will have on about 1.5 billion people of vulnerable densely populated communities in downstream river basins. Yet there is huge uncertainty about how snow and glacial melting in the Himalayan region will continue to respond to climate change, and how such change will affect ecosystems and human well-being. There is a...
Intensification of crop production in the mountains has long been perceived as unsustainable. However, since the late 1980s it has become increasingly evident that decline and collapse are not always inevitable. The present article provides examples from the highlands of northern Thailand to show that local food security can be improved while impacts on the resource base and the environment...
In many developing countries, literacy has been seen as the key to 'women's development' resulting in a proliferation of women's literacy programmes run by both Governments and Non Governmental Organisations. Nepal is one such example of a country where literacy programmes have been used extensively as an entry point for involving women in development activities. The author's experience of...
The human dimension of development processes in high mountain regions regularly escapes appropriate assessment due to a lack of applicable methods. Comparative data are lacking, and it is difficult to substantiate the position of mountain societies within nation-states. In view of the International Year of Mountains, consideration should be given to the focus of research and the need for...
MRD asked Susanne Wymann von Dach, geographer and MRD Assistant Editor, to interview Engelbert Ruoss, a biologist and museologist who is project manager of the Entlebuch Biosphere Reserve (Projekt Biosphärenreservat Entlebuch, Chlosterbüel, 6170 Schüpfheim, Switzerland) and lectures at the Institute for Environmental Research (NLU), University of Basle. The interview was...
