Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the assessment of soil organic carbon (SOC) sequestration potential in agroforestry systems. Agroforestry systems, which integrate trees with crops or livestock, have gained recognition for their potential to enhance soil health, biodiversity, and ecosystem services. The focus of this study is to evaluate the role of agroforestry systems in sequestering soil organic carbon, a critical component for mitigating climate change and improving soil fertility. The research begins with a thorough review of existing literature on soil organic carbon dynamics, agroforestry practices, and their combined impact on carbon sequestration. The literature review highlights the importance of understanding the interactions between tree species, agricultural crops, and soil properties in influencing SOC sequestration rates. Methodologically, a combination of field measurements, laboratory analyses, and modeling approaches are employed to assess SOC sequestration potential in different agroforestry systems. The research methodology involves soil sampling at various depths, carbon content analysis, tree species identification, and data collection on agricultural practices and management strategies. The findings from this study reveal significant variations in soil organic carbon levels across different agroforestry systems, with certain tree-crop combinations showing higher carbon sequestration rates compared to monoculture systems. Factors such as tree species selection, tree density, land management practices, and soil type are identified as key determinants of SOC sequestration potential. In the discussion section, the implications of the research findings are examined in relation to climate change mitigation, soil fertility improvement, and sustainable land management practices. The results underscore the importance of promoting agroforestry systems as a viable strategy for enhancing soil carbon sequestration and overall ecosystem resilience. In conclusion, this thesis provides valuable insights into the assessment of soil organic carbon sequestration potential in agroforestry systems. The research highlights the multifaceted benefits of integrating trees with agricultural practices and underscores the importance of adopting sustainable land management approaches to enhance soil health and mitigate climate change. The findings of this study contribute to the growing body of knowledge on agroforestry systems and their role in promoting carbon sequestration and sustainable agriculture practices.

Thesis Overview

The project titled "Assessment of Soil Organic Carbon Sequestration Potential in Agroforestry Systems" aims to investigate and evaluate the capacity of agroforestry systems to sequester soil organic carbon. This research overview provides a detailed explanation of the project, highlighting its significance, objectives, methodology, and expected outcomes. **Significance of the Study:** The global climate crisis has heightened the urgency to explore sustainable agricultural practices that can mitigate greenhouse gas emissions and enhance carbon sequestration. Agroforestry systems, which integrate trees and crops on the same land, have shown promising potential in promoting soil health and increasing carbon storage. Understanding the specific mechanisms through which agroforestry systems enhance soil organic carbon sequestration is crucial for informing policy decisions and agricultural practices aimed at achieving climate resilience. **Objectives of the Study:** The primary objective of this research is to assess the soil organic carbon sequestration potential of agroforestry systems. Specific objectives include: 1. To investigate the impact of different agroforestry practices on soil organic carbon levels. 2. To quantify the amount of soil organic carbon stored in agroforestry systems compared to conventional agricultural systems. 3. To analyze the factors influencing soil organic carbon sequestration in agroforestry systems. 4. To assess the long-term sustainability of soil organic carbon sequestration in agroforestry systems. **Methodology:** The research will employ a combination of field surveys, soil sampling, laboratory analyses, and data modeling to achieve the research objectives. Field surveys will be conducted in selected agroforestry sites to assess the types of agroforestry practices in place and their spatial distribution. Soil samples will be collected from different depths and locations within agroforestry systems and adjacent conventional agricultural fields for analysis of soil organic carbon content. Laboratory analyses will include soil carbon fractionation to determine the stability and composition of soil organic carbon pools. Data modeling will be used to extrapolate the findings to assess the overall carbon sequestration potential of agroforestry systems. **Expected Outcomes:** The research is expected to provide valuable insights into the role of agroforestry systems in enhancing soil organic carbon sequestration. The findings will contribute to the existing knowledge on sustainable agricultural practices and their potential to mitigate climate change. By quantifying the soil organic carbon storage capacity of agroforestry systems, this research aims to inform policy-makers, farmers, and stakeholders on the benefits of adopting agroforestry practices for climate resilience and sustainable land management. In conclusion, the project "Assessment of Soil Organic Carbon Sequestration Potential in Agroforestry Systems" seeks to bridge the gap in understanding the contribution of agroforestry systems to soil organic carbon sequestration. Through a comprehensive assessment of soil carbon dynamics in agroforestry settings, this research aims to promote the adoption of practices that enhance carbon storage in agricultural landscapes, contributing to climate change mitigation and sustainable land management.
