Editing IPCC:AR6/SRCCL/Chapter-6 (section)

=== 6.1.1 Context of this chapter ===

<div id="section-6-1-1-context-of-this-chapter-block-1"></div>

This chapter focuses on the interlinkages between response options <sup>[[#fn:1|1]]</sup> to deliver climate mitigation and adaptation, to address desertification and land degradation, and to enhance food security. It also assesses reported impacts on Nature’s Contributions to People (NCP) and contributions to the UN Sustainable Development Goals (SDGs). By identifying which options provide the most co-benefits with the fewest adverse side effects, this chapter aims to provide ''integrated response options'' that could co-deliver across the range of challenges. This chapter ''does not consider response'' options that affect only one aspect of climate mitigation, adaptation, desertification, land degradation, or food security in isolation, since these are the subjects of Chapters 2–5; this chapter ''considers only'' interlinkages between response options, and two or more of these challenges in the land sector.

Since the aim is to assess and provide guidance on integrated response options, each response option is first described and categorised, drawing on previous chapters 2–5 (Section 6.2), and their impact on climate mitigation/adaptation, desertification, land degradation, and food security is quantified (Section 6.3). The feasibility of each response option, respect to costs, barriers, saturation and reversibility is then assessed (Section 6.4.1), before considering their sensitivity to future climate change (Section 6.4.2).

The ''co-benefits'' ''and adverse side effects'' <sup>[[#fn:2|2]]</sup> of each integrated response option across the five land challenges, and their impacts on the NCP and the SDGs, are then assessed in Section 6.4.3. In section 6.4.4, the spatial applicability of these integrated response options is assessed in relation to the location of the challenges, with the aim of identifying which options have the greatest potential to co-deliver across the challenges, and the contexts and circumstances in which they do so. Interlinkages among response options and challenges in future scenarios are also assessed in Section 6.4.4. Finally, Section 6.4.5 discusses the potential consequences of delayed action.

In providing this evidence-based assessment, drawing on the relevant literature, this chapter does not assess the merits of policies to deliver these integrated response options – Chapter 7 assesses the various policy options currently available to deliver these interventions. Rather, this chapter provides an assessment of the integrated response options and their ability to co-deliver across the multiple challenges addressed in this Special Report.
