Carbon sequestration opportunities in soils in Latin America and the Caribbean
"Carbon sequestration" is defined as the removal of CO2 from the atmosphere and its storage in ecological sinks, such as soil organic matter. In this case, carbon sequestration will be quantified, as changes in the soil organic carbon (SOC) pool. That can occur in response to changes in land management, such as increased use of fertilization, irrigation, or in response to changes in land use, that is, the conversion of crops to afforestation.
LAC soils could have a relevant role in SOC carbon sequestration since, depending on their management, pastures and agricultural soils have potential as large SOC sinks. Therefore, management strategies such as the inclusion of service crops in agricultural sequences, the integration of agricultural and livestock systems, the increase in the availability of water and nutrients (irrigation, fertilization, amendments), and the restoration of sown pastures and degraded natural pastures. In each country, the most effective strategy to increase the national stock of COS will depend on the expected sequestration rates and the area covered by such systems in LAC.
The objective of this project is to contribute to the design of land uses and management with a high potential for SOC sequestration in the agricultural production systems of LAC and to generate capacities in LAC for the quantification and monitoring of the SOC stock. This objective will be achieved, through the development of a multi-agency platform that provides LAC countries with information to report their SOC inventories in TIER2.
The technological solution
Identification, and evaluation of strategies, to intensify agricultural production systems in LAC with the potential for mitigating and adapting to climate change.
The results of this project are:
1. Generated references for the agencies in charge of reporting the national GHG inventories in each country and for those agencies involved in the generation of NDCs and NAMAs.
2. An opportunity identified for the sequestration of COS will be obtained, with potential for implementation as a NAMA evaluated in its potential economic and environmental impact for the five LAC countries participating in the project.
3. Traine staff to update their SOC stock reports and stock changes with the necessary quality in the time required by international agreements in the five participating countries in this project and have the reference material developed in the published component for subsequent consultations.
The direct beneficiaries of the project will be the national entities of Uruguay, Argentina, Chile, Costa Rica, and Colombia in charge of reporting greenhouse gas inventories, especially COS stocks, in the different participating LAC countries. Indirect beneficiaries are neighboring LAC countries with similar agroecosystems to those of the five participating countries will also benefit from the products of this project.
