The percentage composition of carbon in CH₄ is: (a) 25% (b) 50% (c) 78% (d) 100%

In 2023, which of the following is a significant challenge to sustainable agriculture in Nepal’s mountainous regions? (a) Overabundance of agricultural land and labor. (b) Increasing frequency of glacial lake outburst floods (GLOFs) impacting farmland. (c) The complete absence of drought conditions throughout the year. (d) A lack of interest from farmers in adopting modern farming techniques.
सही उत्तर: ख) (b) Increasing frequency of glacial lake outburst floods (GLOFs) impacting farmland

(b) Snowmelt from high-altitude glaciers and rivers. (c) Groundwater reserves within alluvial plains. (d) Rainfall patterns across the Terai region.
सही उत्तर: ख) (b) Snowmelt from high-altitude glaciers and rivers
The Kusum scheme is centrally based on diverting water from Himalayan glacial meltwater. This represents a key strategy to address Nepal’s water resource needs, while volcanic activity doesn't drive this particular project and groundwater reserves are regional rather than national-scale projects.
