How do forests contribute to carbon sequestration and how is this measure used in land-use planning?

• A. Forests store carbon in biomass and soils; sequestration data inform climate mitigation strategies, carbon credits, and land-use policy decisions.
• B. Forests only release carbon during decomposition; sequestration data are irrelevant.
• C. Forest carbon sequestration measures are used solely for academic research with no policy use.
• D. Forests create carbon emissions net through combustion.

Answer: (A)

Forests act as carbon sinks because they pull CO2 from the atmosphere through photosynthesis and store it in living biomass (trunks, branches, leaves) and in soils. The amount of carbon absorbed and accumulated over time—carbon sequestration—can be measured as carbon stocks and fluxes, providing a clear picture of how much climate-regulating value a forest landscape offers. In land-use planning, these measurements guide where to protect existing forests, where to restore or expand forest cover, and how forest management practices (like thinning, fire control, or selecting tree species) influence future carbon uptake. The data are used in climate mitigation efforts, support carbon-credit markets, and shape policies about land-use decisions, tenure, and incentives for conservation or reforestation. To apply this well, planners use tools that estimate carbon in aboveground and soil pools, track changes over time, and account for factors like disturbances and permanence, often combining field inventories with remote sensing. Some statements miss the core point by saying forests only release carbon, or that sequestration data have no policy use; in reality, forests both store carbon and, when managed well, contribute to policy-relevant climate goals.
