Why Science? | Centre for Nature-based Climate Solutions

Photosynthesis, respiration, decomposition, water movement and species interactions influence how ecosystems store carbon and respond to disturbance. A climate intervention must identify the process it expects to change.

A nature-based climate solution is both an ecological intervention and a climate claim. Carbon, biodiversity, water, livelihoods and governance need separate measures before they can be discussed together. The practical capability is ecosystem-process literacy. Keep the question, source, method, observation, uncertainty, review and next decision together in one dated evidence receipt. That trail lets another reader see what the work establishes and where the claim must stop. CNCS, NUS and research partners control current projects and released findings; land managers, communities and responsible authorities control access, safeguards, policy and implementation.

Put this into practice by turning the idea into a small, reviewable action: Create a one-page evidence card for “Nature-based solutions begin with ecosystem processes” with the question, source or sample, method, observation, limitation and next check. Then ask what the resulting note or artefact actually demonstrates. A useful record names context, source or instruction, action, observation, interpretation and uncertainty. It also preserves this limit: A green appearance is not a measurement of climate benefit.

An evidence check keeps confidence proportional to what the work can show. Separate the original observation or official statement from the learner’s explanation. Record feedback and any revision. If information is missing, write “not shown” or “not yet known” rather than guessing. That honest gap can become the next question.

Mitigation reduces emissions or increases removals; adaptation reduces harm from climate impacts. One ecosystem action may contribute to both, but each outcome needs its own indicator and baseline.

Tropical landscapes change across space and time. Field plots, remote sensing, historical records and models become useful when their scales, assumptions and uncertainties are aligned.
