Forests play a crucial role in mitigating climate change by absorbing and storing carbon dioxide (CO₂) through photosynthesis and other biophysical processes. This review highlights the importance of afforestation and reforestation in reducing global CO₂ emissions and enhancing climate resilience. Forests act as significant carbon sinks, with their capacity to sequester carbon influenced by factors such as tree species, age, and local climate conditions. However, deforestation, wildfires, and other disturbances threaten forest ecosystems and their ability to store carbon. The Paris Agreement aims to limit global warming to below 2°C, with afforestation and reforestation being key strategies to achieve this goal. Despite their potential, the effectiveness of these actions depends on strategic planning, implementation, and local conditions. Integrating afforestation with other carbon removal technologies can enhance long-term carbon storage. The review also emphasizes the need for sustainable forest management, biodiversity conservation, and community involvement to ensure the success of climate change mitigation efforts. Overall, forests are vital for climate stability, but their role is increasingly at risk due to natural and human-induced pressures. Effective climate change mitigation requires restoring and establishing forests, reducing greenhouse gas emissions, and adopting sustainable practices that balance environmental, social, and economic needs.Forests play a crucial role in mitigating climate change by absorbing and storing carbon dioxide (CO₂) through photosynthesis and other biophysical processes.
