CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Layanan lingkungan agroforestri berbasis kopi: cadangan karbon dalam biomasa pohon dan bahan organik tanah (studi kasus dari Sumberjaya, Lampung Barat)

Export citation

Loss of carbon (C) stocks from terrestrial ecosystems continues to be a significant contributor to the increasing concentrations of greenhouse gases in the atmosphere. Forest conversion to intensive agricultural systems leads to a reduction of ecosystem C stocks, mainly due to removal aboveground biomass as harvest and loss of C asCO2 through farm activity such as burning and decomposition of organic materials. We estimated the C sequestered by vegetation derived initially by complete land clearing, based on C stored in the biomass, necromass and in the soil as soil organic matter (SOM). This research was conducted in 1998 and 2001/2002 in agroforestry gardens in Sumberjaya (West Lampung). The purpose of this research was (1) to estimate the C stock in agroforestry coffee based system, (2) to measure the C stock of shade trees in coffee based agroforestry systems, (3) To measure the soil C stock. The measurements were done along Way Besai catchment covering five type of land uses i.e. Remnant forest, coffee based agroforestry system (multistrata coffee system), shaded- coffee system, and monoculture (sun) coffee system. Agroforestry systems in Sumberjaya maintain above-ground C stocks of about 18 21 Mg ha-1 compared to 10 Mg ha-1 for sun coffee, and 195 Mg ha-1 for remnant forest. The soil C stock in the agricultural system was 50% lower than that in the forest (64 Mg ha-1). The annual C accumulation rate of the coffee-based systems was about 0.9 Mg C ha-1 yr-1, and 0.6 Mg ha-1 for shaded coffee systems. As a part of Clean Development Mechanism, further activity on identification of tree diversity and C stock of different of agroforestry types inIndonesia is still needed..
