The objective of this work was to assess the effects of integrated crop-livestock systems, associated
with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four
Soil microbial biomass is considered as an important early indicator of changes that may occur
in the long term with regard to soil fertility and constitutes an important source and sink of nutrients. In
Land degradation through extensification of agriculture and overgrazing is an increasing problem across large expanses of the Ethiopian highlands that give rise to a loss in a range of ecosystem services.
In the West African drylands, SOC sequestration is seen as one of the prominent strategies to both enhance the resilience of agro-ecosystems and mitigate global greenhouse effects.
