The land use, land-use change and forestry (LULUCF) sector, as a source and a sink of greenhouse gas (GHG) emissions, is critical for achieving carbon neutrality. Many academic journals have published papers on land use carbon emission or sink (LUCES), but LUCES reviews are relatively rare, which poses great challenges in accurately understanding t...

Incidences of failure of sustainable ecosystem management policies, especially in the developing world are partly attributable due to a lack of political will and inadequate understanding of ecosystem dynamics (ED) at the local levels. In this study, we endeavor to comprehend the dynamics of two ecosystems-forest and agriculture-by employing a reso...

The efficient use of forest goods and services is crucial for sustainable forest management (SFM). The selective logging (SL) is one of the dominant forest harvesting practices and contributes nearly 15% of global timber need. However, there are contrasting views and opinions about its environmental and economic impacts. This chapter assesses the p...

Globally, small-scale agricultural systems form the main livelihood option for billion plus people and play an important role in food security. However, such agricultural systems have been undergoing unprecedented changes due to multiple change stressors. Previous studies have indicated that the transhumance systems in northern mountainous areas of...

Environmental impact assessment (EIA) has evolved as an environmental management and sustainability tool. Despite common principles shared by EIA globally, there are considerable variations in EIA processes across countries. In this paper, we reviewed and compared EIA processes of China, Queensland State of Australia and Nepal considering five key...

Despite broad scientific consensus on climate change, public views may not always correspond with scientific findings. Understanding public perceptions of climate change is thus crucial to both identifying problems and delivering solutions. Investigations of climate change that integrate instrumental records and people’s perceptions in the Himalaya...

Knowledge of the long-term frequency and intensity of drought events in an area is crucial since drought has adverse effects on natural ecosystems, food security, economy, society, and civilization. We developed a 405-year long (1611–2015C.E.) tree-ring chronology of Pinus wallichiana (Blue pine) from the Dolpo area of the trans–Himalayan region in...

The theme of global sustainable development has changed from environmental management to climate governance, and relevant policies on climate governance urgently need to be implemented by the public. The public understanding of climate change has become the prerequisite and basis for implementing various climate change policies. In order to explore...

Grazing-based livestock production, named pastoralism, is classified into nomadism, transhumance and agro-pastoralism. Transhumance is characterised by the seasonal and recurring movement of livestock whereby seasonal grazing areas and routes for livestock movement are fixed. All grazing based livestock production systems including transhumance are...

Several forest management and conservation models exist throughout the world and Nepal is one of the pioneering countries to implement a community forestry programme. Studying the relationship between carbon stocks and biodiversity is important in understanding the trade-off between two major benefits of forest ecosystems, and working towards achie...

The people living in the agrarian societies develop different strategies in response to climatic variability and environmental uncertainties. Transhumant pastoralists in the Himalayas are among those who follow nature's rhythm of seasonality. The traditional practices built in group's experience might be useful to adapt with climate variability and...

Both climatic and non-climatic factors affect surface water quality. Similar to its effect across various sectors and areas, climate change has potential to affect surface water quality directly and indirectly. On the one hand, the rise in temperature enhances the microbial activity and decomposition of organic matter in the river system and change...

p>Climate change has emerged as a global concern despite its differential impacts across geographical, social and economic gradients. Understanding perceptions of local communities towards climate change is important as it advances the knowledge, and is the driver of autonomous adaptation and behavioral responses. The livelihood of the agro-pastora...

Abstract: Climate change has emerged as one of the pressing problems of the world. The people living in the agrarian societies whose subsistence livelihood depends upon the direct utilisation of natural resources historically develop different strategies in response to climatic variability and environmental uncertainties. Transhumant pastoralists i...

Climatic treelines act as bio-monitors for impacts of climate change on high altitude biota. This dendroecological and dendroclimatological study was carried out at the treeline ecotone of two high mountain protected areas of the Nepal Himalayas: Annapurna Conservation Area and Shey-Phoksundo National Park, to assess the impact of climate change on...

Climate change vulnerability depends upon various factors and differs between places, sectors and communities. People in developing countries whose subsistence livelihood depends mainly upon agriculture and livestock production are identified as particularly vulnerable. Nepal, where the majority of people are in a mixed agro-livestock system, is id...

Indigenous people whose subsistence livelihoods depend upon the direct utilization of natural resources are vulnerable to the impacts of climate change, and can yet be unaware of actual and possible change. Changes in seasonality, temperatures and rainfall could undermine traditional systems built in group's experience. In one such system in the Hi...

Landslides, floods, and droughts are recurring natural disasters in Nepal related to too much or too little water. The summer monsoon contributes more than 80% of annual rainfall, and rainfall spatial and inter-annual variation is very high. The Gandaki River, one of the three major rivers of Nepal and one of the major tributaries of the Ganges Riv...

Grazing systems in the high Himalayas are changing in response to socioeconomic factors and policy decisions. As well as effects on livelihood of herders, such changes may have significant impacts on plant species richness and composition. The objectives of this study were to explore how plant species richness and composition respond to livestock g...

The climate of the Himalayan region is changing rapidly. Decreasing glacier and snow cover are the visible evidences of the change in temperature and precipitation pattern in the Himalayan region. Nepal is considered the fourth most vulnerable country to the impacts of climate change , partly due to the reliance of most of the population on croppin...

Climate change vulnerability depends on who you are, where you are and what you do. The indigenous communities who primarily depend on natural resources for subsistence livelihoods are among the first and most affected by climate change. Climate models have predicted pronounced warming in high altitude regions of the Himalayas. The transhumant comm...

The decline or loss of traditional social-ecological systems may induce adverse effects to the societies and ecosystems. Transhumance, the recurring and seasonal movement of grazing livestock, is increasingly constrained by a numbers of factors including policy, land use and socio-economic changes in Nepal. To explore how these changes have affecte...

One of the major policies in response to global climate change is reduction of green house gases emission. Community forests of Nepal are acting as major sources and sink of green house gases, in spite of providing socioeconomic benefits to the user groups. There is a lack of information on whether community forests address the socioeconomic dispar...

Forests play an important role in the global carbon cycle as both a source and sink of carbon. The carbon stock in a forest is affected by climate, tree species and forest management. The community forestry program of Nepal has been successful in reviving degraded forest patches in the Mid-hills but there is a lack of information whether mixed or p...

Forest can capture and retain large amount of carbon over long periods. To estimate the climate change mitigation potential from carbon stock of the forest, the study was conducted in Ghwangkhola Sapaude Babiyabhir Community Forest (GSBCF) in SyangjaDistrict of Nepal. The total carbon stock of forest was measured from April 1-25, 2011 by following...
