The potency of coffee plants in agroforestry system in Baringin Village, Agam Regency, West Sumatra to support social forestry program and its contribution to mitigate climate change

Abstract

Abstract This study investigates the viability of coffee agroforestry systems in supporting Indonesia’s Social Forestry Program and contributing to climate change mitigation efforts. Conducted in the KUPS Kopi Data Baringin management area of West Sumatra, this research assesses the potential of coffee cultivation within an agroforestry system in Baringin Village, Agam District. Data collection encompassed a comprehensive census for social and economic aspects and purposive sampling for vegetation analysis. Findings revealed a diverse range of 29 tree species from 16 families, alongside eight types of agricultural crops from five families. Tree species exhibited lower diversity and abundance indices, while herbaceous and shrub categories demonstrated moderate diversity. Notably, Coffea canephora, the coffee species, exhibited a carbon content of 3.49 tons per hectare, contributing to climate change mitigation efforts and functioning as a valuable CO2 equivalent sink estimated at approximately 13 tons per hectare. Furthermore, the adoption of coffee agroforestry systems resulted in a notable increase in monthly income for KUPS members. These findings underscore the potential of coffee agroforestry systems as a sustainable land-use practice, supporting the Social Forestry Program objectives and making substantial contributions to climate change mitigation in Indonesia’s forest and land management strategies.
