A Technical Guide for Assessing Nature-Based Mitigation Opportunities in Countries.
Even as the world looks to step up efforts to cut greenhouse gas emissions, the need to adapt to the impacts of climate change already locked in are just as important. The sixth edition of the UNEP Adaptation Gap Report: The Gathering Storm looks at how the world is doing in adapting to these intensifying impacts.
The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.
This report identifies ways to overcome key barriers to private sector investment in adaptation and resilience, laying out a coordinated and data-driven Blueprint for Action to help governments and their development partners to close the adaptation finance gap. Although climate adaptation finance flows have increased by 35% in recent years, they still fall short of what is needed to avoid severe economic and human impacts from climate change. The urgent need for boosting investment in climate adaptation and resilience cannot be overstated. The blueprint provides five entry points to enable private investment. The Blueprint for action we propose in the report represents a novel coordinated framework for action for governments to develop, finance, and implement priority adaptation and resilience investments – driven by countries’ goals and national investment plans that can help accelerate and scale up investment to address the climate resilience needs of the world’s most climate-vulnerable communities and economies.
Water supply and sanitation (WSS) utilities are expected to become increasingly susceptible to the expected impacts of climate change. WSS utility planners and engineers have dealt with natural climate variances and disaster planning as part of the design process for many years. However, the traditional methods for these plans have not considered the deep uncertainty surrounding many future conditions, which are further exacerbated by climate change. To help utilities incorporate resilience and robustness in their choices, this road map proposes a process in three phases that can inform the design of strategies necessary to WSS services provision. The road map builds on the understanding that climate change is most often an amplifier of existing uncertainties (many of which are threats), and, as such, should not be evaluated as a stand-alone impact. The approach reveals the strengths and vulnerabilities of investment plans concisely and helps utilities invest robustly by identifying near-term, no-regret projects that can be undertaken now, while maintaining flexibility in pursuing additional actions adaptively as future conditions evolve. These results can be achieved both with a qualitative exploration and a quantitative assessment, depending on the context and the resources available.
The purpose of the Resilient Water Infrastructure Design Brief is to guide users on how resilience can be built into the engineering design of their project. With a focus on the three natural hazards most likely to affect water and sanitation infrastructure (droughts, floods, and high winds from storms), the document provides a six-step process to help users address weather and climate related challenges that are most likely to affect an infrastructure component at some point in its operational lifetime. In order to achieve both systems level resilience and infrastructure level resilience, this design brief should be used in tandem with other World Bank publications, such as the 2018 guidance document “Building the Resilience of WSS Utilities to Climate Change and Other Threats: A Road Map,” which emphasizes systems level resilience and analysis. The design brief highlights the relationship between these two documents and the unique function that each serves in improving overall resilience in the water sector. It also includes guidance for users to incorporate resilience design principles into projects’ appraisal documents and a sample module/task description for applying the two documents to an engineering design or feasibility study terms of reference.
