Alpine pastures, Trans-Himalayan zones, and Himalayan forest grazing grounds support significant populations of:
Show answer Hide answer
Answer: D. All of the above
Explanation
Alpine pastures and Himalayan forest grazing grounds support vital water resources. Rivers, perennial springs, and seepage water provide essential hydration for livestock. High-altitude ecosystems act as natural water towers supplying downstream agricultural valleys. Mountain hydrology depends on snowmelt and glacial runoff feeding numerous perennial streams. Grazing livestock in alpine zones require reliable water sources during seasonal transhumance. Forest soils retain moisture and release it slowly through underground seepage mechanisms.
Pastoralist communities rely on high-altitude water points to sustain herds during summer months. Watershed protection in the Himalayas is critical for downstream agricultural irrigation security. Climate change threatens mountain water supplies, impacting both livestock and human populations. Rivers represent only one component of the diverse water resources found in mountain pastures. Perennial springs provide localized water without capturing the broader river and seepage systems. Seepage water alone does not encompass surface rivers and flowing mountain spring networks.
