Chapter 1: Point of Departure and Key Concepts

Executive Summary

The concepts of adaptation, vulnerability, resilience and risk provide overlapping, alternative entry points for the climate change challenge (high confidence). Vulnerability is a component of risk, but also an important focus independently, improving understanding of the differential impacts of climate change on people of different gender, race, wealth, social status and other attributes.

1.1 The Current Urgent Moment

1.1.1 A Changing Climate in a Changing World

These include species and ecosystems loss due to land and sea use change and pollution (IPBES, 2019a); a growing and urbanising world population (Gerten et  al., 2019; van Vliet et  al., 2017); technology reshaping the workplace through automation (Schwab, 2017) and information dissemination through social media (Mavrodieva et  al., 2019; Pearce et al., 2019); and increasing inequalities due to gender, poverty, age, race and ethnicity (Cross-Chapter Box GENDER in Chapter 18). 

1.2 Different Entry Points for Understanding Climate Change Impacts, Adaptation and Vulnerability

1.2.1 Overlapping, Complementary Entry Points

The concept of vulnerability can provide a unique window into the effects of climate change on different communities, individuals and ecosystems, in particular as human systems are affected by race, gender, wealth inequalities and other attributes (Section 1.2.1.2).

1.3 Understanding and Evaluating Climate Risks

1.3.1 Nature of Climate Risk

1.3.1.2 The Complexities of Climate Risk

As a result, risks vary at fine scale across communities and societies and also among people within societies, depending, for example, on intersecting inequalities and context-specific factors such as culture, gender, religion, ability and disability, or ethnicity (Kuruppu, 2009; Jones and Boyd, 2011; Carr and Thompson, 2014; also Section 16.1.4).

Fundamental questions about equity and justice in adaptation include gender and intersectionality (see Cross-Chapter Box GENDER in Chapter 18; Section 1.4.1.1; Chapter 18;) and broader critiques of who participates in processes of adaptation planning and implementation, who receives investments, who and what benefits from them, who makes key decisions regarding adjustments through time (Taylor et al., 2014; Boeckmann and Zeeb, 2016; Nightingale et al., 2019; Pelling and Garschagen, 2019; Byskov et al., 2021; Eriksen et al., 2021) and how climate justice intersects with other justice agendas.

Chapter 1: Point of Departure and Key Concepts

Executive Summary

 The concepts of adaptation, vulnerability, resilience and risk provide overlapping, alternative entry points for the climate change challenge (high confidence). Vulnerability is a component of risk, but also an important focus independently, improving understanding of the differential impacts of climate change on people of different gender, race, wealth, social status and other attributes. Vulnerability also provides an important link between climate adaptation and disaster risk reduction. Resilience, which can refer to either a process or outcome, encompasses not just the concept of maintaining essential function, identity and structure, but also maintaining a capacity for transformation. Such transformations bring forth questions of justice, power and politics. {1.2.1; 1.4.1}

1.1 The Current Urgent Moment

1.1.1 A Changing Climate in a Changing World

This report addresses the challenges of climate action in the context of sustainable development. Climate action takes place in a world already undergoing some of the most rapid and significant societal and environmental change in decades (IPCC, 2018b; Box 1.1). These include species and ecosystems loss due to land and sea use change and pollution (IPBES, 2019a); a growing and urbanising world population (Gerten et  al., 2019; van Vliet et  al., 2017); technology reshaping the workplace through automation (Schwab, 2017) and information dissemination through social media (Mavrodieva et  al., 2019; Pearce et al., 2019); and increasing inequalities due to gender, poverty, age, race and ethnicity (Cross-Chapter Box GENDER in Chapter 18). Economic inequality grows within nations even as it has narrowed among them (UN Department of Economic and Social Affairs, 2020). International polycentric governance and non-state actors play an important role (Beck and Mahony, 2018; Sections 1.4.2 and 17.1.2.1). In 2020 and 2021, a global pandemic dramatically affected the lives of most of the world’s population, likely accelerating many of the changes already underway (Cross-Chapter Box COVID in Chapter 7). 

1.2 Different Entry Points for Understanding Climate Change Impacts, Adaptation and Vulnerability

1.2.1 Overlapping, Complementary Entry Points

The concept of vulnerability can provide a unique window into the effects of climate change on different communities, individuals and ecosystems, in particular as human systems are affected by race, gender, wealth inequalities and other attributes (Section 1.2.1.2). The concept of adaptation can provide a unique window into the process of adjustment to climate change by human and natural systems (Section  1.2.1.3). Resilience (Section  1.3.1.4) is a broad concept, encompassing both outcomes and processes, an ability to maintain essential function and an ability to transform.

1.3.1.2 The Complexities of Climate Risk

The dynamic nature of risk and its determinants is one important dimension of complexity. The risk of climate change impacts can be usefully understood as resulting from dynamic interactions among climate-related hazards, the exposure and vulnerability of affected human and ecological systems, and also responses (see Section 1.2.1; AR6 Glossary, IPCC, 2021b; WGI AR6 Cross-Chapter Box 2 in Chapter 1, Chen et al., 2021; Oppenheimer et al., 2014). The determinants of risk all can vary and change through space and time in response to socioeconomic development and decision making (Figures  1.4; 1.5; Section  16.1). Hazards are affected by current and future changes in climate, including altered climate variability and shifts in frequency and intensity of extreme events (WGI AR6 Chapter 12, Ranasinghe et al., 2021). Such hazards can be sudden, for example, a heat wave or heavy rain event, or slower onset, for example, land loss, degradation and erosion linked to multiple climate hazards compounding. The severity of climate change impacts will depend strongly on vulnerability, which is also dynamic and includes the sensitivity and adaptive capacity of affected human and ecological systems (McDowell et al., 2016; Jurgilevich et al., 2017; Ford et al., 2018; Viner et al., 2020). As a result, risks vary at fine scale across communities and societies and also among people within societies, depending, for example, on intersecting inequalities and context-specific factors such as culture, gender, religion, ability and disability, or ethnicity (Kuruppu, 2009; Jones and Boyd, 2011; Carr and Thompson, 2014; also Section 16.1.4). The dynamic social distribution of impacts is the subject of increasing attention within climate assessment and responses, including the role of adaptation, iterative risk management and climate resilient sustainable development (Section 16.1).

Increasingly reflective adaptation research

Another characteristic of recent adaptation research is a stronger focus on ethics, justice and power (Byskov et al., 2021; Coggins et al., 2021; Eriksen et al., 2021; Singh et al., 2021). Researchers and practitioners are increasingly impatient to address the root causes of vulnerability and use inclusive climate adaptation processes to generate effective adaptation responses for marginalised and misrecognised groups (Tschakert et al., 2013; Eriksen et al., 2015; Scoones et al., 2015; Gillard et al., 2016; Wisner, 2016). Increasingly ambitious, normative adaptation research often challenges technological solutions that simply reinforce the existing status quo (Nightingale et al., 2019, p. 2) and calls for ‘socially just pathways for change’. Here work on adaptation overlaps with mitigation, transitions and other large-scale social change, encouraging the move towards more systemic, integrated approaches that discern between options according to multiple criteria (Goldman et al., 2018).

Fundamental questions about equity and justice in adaptation include gender and intersectionality (see Cross-Chapter Box GENDER in Chapter 18; Section 1.4.1.1; Chapter 18;) and broader critiques of who participates in processes of adaptation planning and implementation, who receives investments, who and what benefits from them, who makes key decisions regarding adjustments through time (Taylor et al., 2014; Boeckmann and Zeeb, 2016; Nightingale et al., 2019; Pelling and Garschagen, 2019; Byskov et al., 2021; Eriksen et al., 2021) and how climate justice intersects with other justice agendas. Attention is also turning to relations and tensions between different adaptation approaches, scales, constraints, limits, losses, enablers and outcomes (Barnett et al., 2015; Pelling et al., 2015; Mechler and Schinko, 2016; Crichton and Esteban, 2017; Gharbaoui and Blocher, 2017; Deshpande et al., 2018; McNamara and Jackson, 2019). Evident here is an ongoing, serious knowledge gap around the long-term repercussions of adaptation interventions. There is growing awareness of the need to address the potential for maladaptation (Sections 1.4.2.4; 5.13.3; 15.5.1; 17.5.2; Chapter 4). Concerns about maladaptation have led to renewed calls to open the ‘black box’ of decision making to examine the influence of power relationships, politics and institutional culture (Biesbroek et al., 2013; Eriksen et al., 2015; Goldman et al., 2018), including the power–adaptation linkage itself (Woroniecki et al., 2019), external factors outside the decision-making process (Eisenack et al., 2014) and the influence of leadership on adaptation processes and outcomes (Meijerink et al., 2014; Vignola et al., 2017).

All of these developments indicate that adaptation research is not only more reflexive about some of its central assumptions, methodologies and tools (Biesbroek et al., 2013; Conway and Mustelin, 2014; Nalau et al., 2015; Nightingale, 2015a; Porter et al., 2015; Eriksen et al., 2015; Lubell and Niles, 2019; Woroniecki et  al., 2019; Singh et  al., 2021), but also cognisant of the need to critically consider its underpinning goals, purpose and impact in the world.
