Impact of traditional agroforestry systems on biomass and carbon stock for climate change mitigation in the North-Western Indian Himalayas
摘要
In the wet temperate zone of India, planting trees and rearing of livestock on agricultural land is a widespread, traditional practice. This type of land-use system plays a crucial role in climate change mitigation by sequestering carbon. The socioeconomic and ecological benefits of these systems are widely adopted spanning tropical and temperate regions worldwide, addressing community needs and conferring environmental advantages. However, soil quality along with carbon (C) stock within traditional agroforestry systems (TAFS) are minimally covered. Thus, current research highlights the status and future potential of sustaining biomass and accumulating carbon across different components of TAFS in Himachal Pradesh. This research was carried out in three elevation zone classes: E1 (1800–2100 m), E2 (2100–2400 m), and E3 (>2400 m) and examined biomass, carbon stock, and soil properties across five AFS, including Agri-silviculture, Horti-agriculture, Horti-agri-silviculture, Horti-silvo-pasture, and Silvo-pasture. Total biomass, carbon stock, and soil properties such as pH, electrical conductivity, and soil bulk density differed by elevation zone (p<0.01). It provides valuable insights for optimizing AFS to enhance carbon sequestration, mitigate the effects of global climate change, and reduce greenhouse gas emissions in other vulnerable Himalayan ecosystems.
