Climate adaptation can be effectively mainstreamed within global development policy objectives by adopting an integrated, systematic approach that explicitly links climate impacts and adaptation measures to core development goals, prioritizes equity, and ensures coherent policy and financial support across multiple sectors and levels of governance.
The foundation of effective mainstreaming is the recognition that climate change critically influences key goals related to poverty reduction, water, food, energy, education, and health in developing countries, necessitating that adaptation measures be addressed directly in the context of development policies.
1. Implementing the Stepwise Mainstreaming Approach
A core methodological approach for mainstreaming is the "climate change approach," where vulnerability and adaptation measures are assessed within the context of general development policy objectives. This approach utilizes a limited set of indicators representing focal development policy objectives and follows a stepwise process:
1. Element 1: Climate Conditions, Variability, and Future Changes The initial step involves establishing detailed data on the present climate, its variability, and potential changes over time, ensuring the geographical resolution is sufficient for sectoral and local assessments.
2. Element 2: Selection of Development Indicators Identify and select a limited set of indicators that reflect key economic, social, and environmental policy objectives and are sensitive to climate impacts. These indicators allow climate-development linkages to be addressed. Examples of measurement standards for these indicators include:
◦ Economic: Costs, employment, and investments.
◦ Social: Income generation and distribution, time available for education, and the number of people with different diseases.
◦ Environmental: Greenhouse gas (GHG) emissions, local pollutants, and ecosystem degradation.
3. Element 3: Assessing the Relationship between Climate Variables and Development Indicators Combine climate data (Element 1) and development indicators (Element 2) to understand how sensitive development policies are to the climate. Ideally, this step uses statistical data to provide a basis for projecting future climate change impacts.
4. Element 4: Adaptation Options Identify concrete adaptation options designed to make current and future development states better adapted to the climate. This final step includes measuring the costs and development impacts associated with implementing these options.
The core aim of this mainstreaming assessment is to ensure that current and future development policies are adequately adapted to the climate. Case studies confirm that climate risks can often be reduced at relatively low costs.
2. Adopting Integrated and Inclusive Strategies
Effective mainstreaming relies on integrating adaptation into broader policy goals, particularly achieving "climate resilient development," which integrates adaptation and mitigation to advance sustainable development for all.
A. Policy and Sectoral Integration:
• Treat Climate Change as a Development Problem: Mainstreaming requires framing climate change as a development issue, linking human welfare and social dimensions to environmental issues.
• Multi-Sectoral Engagement: The issue must move into the domain of multiple sectors, including agriculture, water, health, energy, and infrastructure. For example, green infrastructure in cities serves both mitigation (carbon sequestration) and adaptation (reducing heat, managing stormwater).
• Integrated Planning: Effective climate governance requires coordination across multiple policy domains and governance levels. Planning should be flexible, multi-sectoral, inclusive, and long-term to avoid maladaptation (actions that focus only on short-term gains or isolated sectors and worsen existing inequities over time).
• Harnessing Synergies with SDGs: Mitigation and adaptation actions have more synergies than trade-offs with Sustainable Development Goals (SDGs). Implementing both together supports co-benefits, such as improved agricultural productivity, innovation, and health. For instance, improved energy access benefits health, especially for women and children, while also enhancing air quality.
B. Prioritizing Equity and Inclusion:
• Focus on Vulnerable Populations: Prioritizing equity, social justice, and inclusion can enable ambitious adaptation actions and climate resilient development. Adaptation outcomes are enhanced by increased support to regions and people with the highest vulnerability to climatic hazards, such as the 3.3 to 3.6 billion people currently living in highly vulnerable contexts.
• Integrating Social Protection: Integrating climate adaptation into social protection programs, such as cash transfers and public works, is highly feasible and increases resilience, particularly when supported by basic services and infrastructure.
• Inclusive Governance: Effective multilevel governance is enabled by inclusive decision processes that prioritize equity and justice in planning and implementation, addressing context-specific inequities related to gender, ethnicity, disability, age, location, and income. Drawing on diverse knowledge systems, including Indigenous knowledge, local knowledge, and scientific knowledge, also facilitates climate resilient development.
3. Securing Finance and Operational Support
Despite documented progress in adaptation, current global financial flows are insufficient and constrain the implementation of adaptation options, especially in developing countries. Effective mainstreaming requires enhanced financial support and institutional capacity.
• Increase Financial Flows: If climate goals are to be achieved, financing for both adaptation and mitigation needs to increase many-fold. Accelerated financial support for developing countries from developed countries and other sources is a critical enabler.
• Leveraging Public Finance: Public finance is important for adaptation and mitigation, and can be used to leverage private finance.
• Institutional Alignment: Effective climate action requires well-aligned multilevel governance, institutional frameworks, laws, policies, and strategies. It is vital to engage urban infrastructure specialists and country counterparts early in the project preparation process and demonstrate that climate change mitigation generates local co-benefits that contribute to general sector objectives.
• Capacity Building: Mainstreaming requires accelerating knowledge management efforts (e.g., developing handbooks on indicative climate change mitigation measures) and undertaking analytic work to match climate change mitigation modalities with specific urban sector priorities. Training and capacity building, particularly for urban officials and planners, are essential to enhance adaptation and ensure the adoption of low-emission technologies, which currently lags in most developing countries.
