Adaptation
Explanation #
Adaptation refers to the process of adjusting natural or human systems in response to actual or expected climate impacts, aiming to reduce harm or exploit beneficial opportunities. It involves modifications to infrastructure, practices, and policies to cope with changes such as sea‑level rise, heat waves, or altered precipitation patterns.
Example #
Raising the elevation of coastal roads to remain functional during higher tides.
Practical applications #
Designing flood‑resilient housing, altering crop calendars, implementing early‑warning systems.
Challenges #
Limited financial resources, uncertainty about future climate trajectories, and the need for coordinated action across sectors and jurisdictions.
Biodiversity #
Biodiversity
Explanation #
Biodiversity encompasses the variety of life at genetic, species, and ecosystem levels. In the context of sustainable development, it underpins ecosystem resilience, supports food security, and provides raw materials for medicines and industry.
Example #
Diverse pollinator populations enhancing crop yields in agricultural landscapes.
Practical applications #
Establishing protected areas, restoring degraded wetlands, and promoting agroforestry.
Challenges #
Habitat fragmentation, climate‑induced shifts in species distributions, and insufficient integration of biodiversity considerations into development planning.
Carbon Pricing #
Carbon Pricing
Explanation #
Carbon pricing assigns a monetary cost to greenhouse‑gas emissions, incentivizing emitters to reduce their carbon footprint. Two main mechanisms are cap‑and‑trade systems and carbon taxes. By internalising the external cost of emissions, it drives investment in low‑carbon technologies.
Example #
A national carbon tax that charges $50 per tonne of CO₂ emitted by power plants.
Practical applications #
Funding renewable‑energy projects, encouraging energy efficiency upgrades, and supporting climate‑friendly innovation.
Challenges #
Setting an appropriate price level, preventing carbon leakage, and ensuring equity for low‑income households and vulnerable communities.
Decarbonisation #
Decarbonisation
Explanation #
Decarbonisation is the systematic reduction of carbon dioxide and other greenhouse‑gas emissions across the economy, aiming to limit global warming. It involves shifting from fossil‑fuel‑based energy to renewable sources, improving energy efficiency, and adopting carbon‑capture technologies.
Example #
Replacing coal‑fired power plants with wind farms and solar arrays.
Practical applications #

Challenges #
High upfront capital costs, grid integration issues, and the need for skilled workforce development.
Ecosystem Services #
Ecosystem Services
Explanation #
Ecosystem services are the benefits that humans obtain from natural ecosystems, including provisioning (food, water), regulating (climate, flood control), cultural (recreation), and supporting (nutrient cycling) services. Recognising their value is essential for sustainable development and climate‑risk management.
Example #
Mangrove forests absorbing storm surge energy, protecting coastal communities.
Practical applications #
Incorporating ecosystem‑service valuation in cost‑benefit analyses, incentivising conservation through payment‑for‑ecosystem‑service schemes.
Challenges #
Quantifying services in monetary terms, integrating them into policy frameworks, and addressing trade‑offs between development and conservation.

Resilience #
Resilience
Explanation #
Resilience is the capacity of a system—be it ecological, social, or economic—to absorb disturbances, reorganise, and continue functioning in the face of climate‑related shocks. It emphasizes flexibility and learning, rather than simply resisting change.
Example #
A coastal community that diversifies livelihoods between fishing and tourism, reducing dependence on a single climate‑sensitive sector.
Practical applications #
Building modular infrastructure, fostering community‑based disaster risk management, and promoting diversified agricultural practices.
Challenges #
Measuring resilience across diverse contexts, preventing “resilience‑washing” where superficial actions mask deeper vulnerabilities, and securing long‑term investment.
