Deforestation releases carbon dioxide, methane, and nitrous oxide, all of which are greenhouse gases. Oxygen is not a greenhouse gas.

Deforestation is estimated to contribute 10-20% of global greenhouse gas emissions.

Forests provide numerous benefits in climate change mitigation, including carbon sequestration, evapotranspiration, and the albedo effect. Aerosol emissions are not a benefit of forests.

Afforestation refers to the planting of trees in areas that were not previously forested. Reforestation refers to the planting of trees in areas that were previously forested but have been cleared.

Agroforestry, which involves the integration of trees into agricultural systems, is an effective land use practice for reducing greenhouse gas emissions.

Land use mitigation refers to the practices and strategies employed to reduce greenhouse gas emissions from land use activities.

While competing land use demands, lack of financial resources, and political will are challenges in implementing land use mitigation strategies, technical constraints are not a significant barrier.

Carbon forestry refers to the management of forests specifically for the purpose of increasing carbon sequestration and mitigating climate change.

Sustainable forest management provides numerous benefits, including reduced deforestation, increased carbon sequestration, and enhanced biodiversity. It does not lead to increased water pollution.

REDD+ (Reducing Emissions from Deforestation and Forest Degradation) is a framework that aims to reduce emissions from deforestation and forest degradation, and promote sustainable forest management.

REDD+ includes reducing emissions from deforestation, reducing emissions from forest degradation, and conserving forest carbon stocks. Increasing forest carbon stocks is not a specific component of REDD+.

Land restoration refers to the process of converting degraded or unproductive land into productive land, often through practices such as reforestation, afforestation, and agroforestry.

Land restoration provides numerous benefits, including increased carbon sequestration, reduced soil erosion, and improved water quality. It does not lead to increased greenhouse gas emissions.

Land use management refers to the process of managing land to achieve specific objectives, such as minimizing greenhouse gas emissions and enhancing carbon sequestration.

Sustainable land use management principles include minimizing land use change, promoting efficient land use, and conserving biodiversity. Maximizing land use intensity is not a principle of sustainable land use management.
