Land Use, Land-Use Change, and Forestry Sector Emissions and Sequestration
The Land Use, Land-Use Change, and Forestry (LULUCF) sector plays a dual role in climate change, acting both as a source of greenhouse gas emissions and as a significant carbon sink. Emissions from this sector arise primarily from deforestation, land clearing for agriculture, and other changes in land use. These activities release large amounts of carbon dioxide (CO2) stored in trees and soil into the atmosphere, contributing to global warming.
Deforestation, especially in tropical regions, is a major driver of CO2 emissions. When forests are cleared or burned, the carbon stored in trees is released, and the land often becomes a source of emissions if it is converted to agriculture or other non-forest uses. Additionally, practices such as peatland drainage and soil disturbance further exacerbate the release of greenhouse gases, including methane (CH4) and nitrous oxide (N2O).
Conversely, the LULUCF sector also has a critical role in carbon sequestration—the process of capturing and storing atmospheric CO2. Forests, wetlands, grasslands, and other ecosystems absorb CO2 through photosynthesis, acting as carbon sinks. Effective forest management, reforestation, afforestation, and the restoration of degraded lands can enhance this natural sequestration capacity.
To mitigate emissions and enhance sequestration, several strategies can be employed. Protecting existing forests from deforestation and degradation is paramount. Implementing sustainable land management practices, such as agroforestry and conservation agriculture, can reduce emissions from land-use changes while improving soil health and productivity. Reforestation and afforestation efforts, along with the restoration of wetlands and other carbon-rich ecosystems, can significantly increase the amount of carbon sequestered.
Policy measures, including stronger enforcement of land protection laws, incentives for sustainable land use, and support for conservation projects, are essential for achieving these goals.
