摘要

The poor management resources, lack of adequate technology, literacy, and policies that limit land restoration practices, have become a great challenge in the tropics, especially in sub-Sahara Africa and Asia. The increase in CO2 and other greenhouse gas emissions, coupled with several human activities, has degraded arable land in the tropics. Better understanding and management of soil quality and soil health is pivotal in restoring land to optimum production levels. The native and dynamic soil quality parameters (which are two broad aspects of soil resources) require more attention in our effort to restore land for food security. Regenerative management practices for climate change mitigation are practices that increase soil C pools, soil quality, and soil health conditions. These practices aim at increasing the amounts of biomass to the soil, increasing soil carbon sequestration (SOC) content, minimizing soil disturbance, conserving soil and water, improving soil structure, enhancing activity and species diversity of soil fauna, and strengthening mechanisms of nutrient cycling. Some traditional techniques adopted by smallholder farmers in eastern Nigeria for combating the effects of climate change have been efficient and can be adopted for use in other parts of the tropics. Researchers and policy makers need to invest in soil C sequestration, and these techniques employed by these farmers in this region for optimal food production and soil functions especially in the tropics which bears the bulk of the impact of climate change.
