“…It is divided into five physiographic zones -high mountains, middle mountains, hills, Siwalik and Terai (Fig. 1b), and administratively into 75 districts and 4057 village development committees (VDCs), which are grouped into five development regions -far western, mid-western, western, central and eastern (Uddin et al 2015). Nepal predominantly exhibits mountainous terrain with elevation ranging from 58 m above mean sea level (amsl) in the southern plains to 8848 m amsl at Mount Everest in the north (Fig.…”

“…The Intergovernmental Panel on Climate Change (IPCC) has recognised the HKH region as a 'data deficit area ' (IPCC 2007). In the last few decades, the HKH region has undergone rapid economic, social and environmental changes (Uddin et al 2015). Under such transitions, the land use and land cover are experiencing changes due to natural and anthropogenic causes.…”

Abstract. Forest fire is one of the key drivers of forest degradation in Nepal. Most of the forest fires are human-induced and occur during the dry season, with ,89% occurring in March, April and May. The inaccessible mountainous terrain and narrow time window of occurrence complicate suppression efforts. In this paper, forest fire patterns are analysed based on historical fire incidence data to explore the spatial and temporal patterns of forest fires in Nepal. Three main factors are involved in the ignition and spread of forest fires, namely fuel availability, temperature and ignition potential. Using these factors a spatially distributed fire risk index was calculated for Nepal based on a linear model using weights and ratings. The input parameters for the risk assessment model were generated using remote sensing based land cover, temperature and active fire data, and topographic data. A relative risk ranking was also calculated for districts and village development committees (VDCs). In total, 18 out of 75 districts were found with high risk of forest fires. The district and VDC level fire risk ranking could be utilised by the Department of Forest for prioritisation, preparedness and resource allocation for fire control and mitigation.Additional keywords: fire behaviour, fire danger, fire management, fire risk.

“…In ancient times, there were many instances of harmful human activity affecting the Earth's landscape (Marsh 1864), and recent decades have provided valuable ideas, methods, tools and techniques to minimize impacts caused by LULC changes. Some researchers have conducted excellent work, documenting these historical changes globally (Ramankutty and Foley 1999;Pongratz et al 2008) or nationally (LRMP 1986;Uddin et al 2015). The process of land use and land cover change (LUCC) is very complex and takes different forms, with differences in magnitude and rate.…”

“…According to the theory of Himalayan Environmental Degradation, high population growth rate, economic activities based on natural resources and poverty have caused mass forest degradation and have had an adverse effect on the environment (Ives and Messerli 1989); this relates directly to LUCC issues in Nepal. There are a number of studies on the causes, pathways and pace of LUCC, as regards cropland, forest, grassland, snow/glacier cover and urban land in various areas of Nepal (Bajracharya 1983;Mahat 1985;Mahat et al 1986;Virgo and Subba 1994;Shrestha and Brown 1995;Khanal 2002;Sharma 2003;Khanal and Watanabe 2006;Bajracharya et al 2014;Uddin et al 2015). Forms of land use such as grazing, shifting cultivation, deforestation, urbanization and land degradation have also been major players in LUCC in the past.…”

Novice efforts have been made in order to study the regional distribution of land surface heat fluxes on the southern side of the central Himalayas utilizing high‐resolution remotely sensed products, but these have been on instantaneous scale. In this study the Surface Energy Balance System model is used to obtain annual averaged maps of the land surface heat fluxes for 11 years (2003–2013) and study their annual trends on the central Himalayan region. The maps were derived at 5 km resolution using monthly input products ranging from satellite derived to Global Land Data Assimilation System meteorological data. It was found that the net radiation flux is increasing as a result of decreasing precipitation (drier environment). The sensible heat flux did not change much except for the northwestern High Himalaya and High Mountains. In northwestern High Himalaya sensible heat flux is decreasing because of decrease in wind speed, ground‐air temperature difference, and increase in winter precipitation, whereas in High Mountains it is increasing due to increase in ground‐air temperature difference and high rate of deforestation. The latent heat flux has an overall increasing trend with increase more pronounced in the lower regions compared to high elevated regions. It has been reported that precipitation is decreasing with altitude in this region. Therefore, the increasing trend in latent heat flux can be attributed to increase in net radiation flux under persistent forest cover and irrigation land used for agriculture.
