The potential for soil carbon sequestration in three tropical
dryland farming systems of Africa and Latin America: A modelling
approach Publikation/Tidskrift/Serie: Soil & Tillage Research
Historically, agriculturally induced CO2 release from soils has
contributed to rising levels in the atmosphere. However, by
using appropriate management, soils can be turned into carbon
sinks. Many of the dryland regions of the world are
characterised by degraded soils, a high incidence of poverty and
a low capacity to invest in agriculture. Two well-proven soil
organic matter models (CENTURY 4.0 and RothC-26 3) were used two
explore the effects of modifying agricultural practices to
increase soil carbon stocks. The changes to land management were
chosen to avoid any significant increase in energy input whilst
using technologies that would be available without radically
altering the current agricultural methodology. Case studies were
selected from dryland farming systems in Nigeria, Sudan and
Argentina. Modelling showed tha
