It is enshrined in the constitution of the kingdom of Bhutan that every Bhutanese is a trustee of the Kingdom’s natural resources and environment for the benefit of the present and future generations and that the government shall protect, conserve and improve the pristine environment and safeguard the biodiversity of the country. Despite such a colossal commitment, Bhutan is still considered highly vulnerable to the impacts of climate change. The vulnerability to the impacts of climate change largely emanates from its rugged mountainous ecosystem, steep geo-physical setting due to its location in the Himalayas with altitudes ranging from 150 to 7,500 meters (m) above sea level (asl), and its weak economic structure as a least developed country. Over 69% of the population dwell in rural areas and are largely dependent on agriculture for their livelihood. It is a landlocked country and surface transport is the most reliable form of connectivity in the country. In the recent years Bhutan has been confronted with varying magnitudes of the impacts of climate change on the sources of rural livelihoods and biodiversity. The country has been struggling to reduce and adapt to these impacts in order to sustainably improve the resilience of the rural communities and conservation of the biodiversity. The future climate change projections for Bhutan indicate that as compared to the 1980-2009 periods the mean annual temperature is projected to increase by 0.8°C to 1.0°C by 2010- 2039 and further by 2.0°C -2.4°Cfor the period 2040-2069. The summer temperatures are projected to increase by 0.8°C in 2010-2039 and further increase by 2.1 °C by 2040-2069. The winter temperature is projected to increase by much higher range of 1.2°C rise for 2010- 2039 time slice and by 2.8°C for the period 2040-2069.With
