In this section, the impacts on desertification of integrated response options based on value chain management are assessed.

''Integrated response options based on value chain management through demand management''

Dietary change and waste reduction both result in decreased cropland and pasture extent (Bajželj et al. 2014a <sup>[[#fn:r531|531]]</sup> ; Stehfest et al. 2009 <sup>[[#fn:r532|532]]</sup> ; Tilman and Clark 2014 <sup>[[#fn:r533|533]]</sup> ), reducing the pressure for desertification (Table 6.34).

Reduced post-harvest losses could spare 1.98 Mkm2 of cropland globally (Kummu et al. 2012 <sup>[[#fn:r534|534]]</sup> ). Not all of this land could be subject to desertification pressure, so this represents the maximum area that could be relieved from desertification pressure by reduction of post- harvest losses. No studies were found linking material substitution to desertification.

Table 6.34 summarises the impacts on desertification of demand management options, with confidence estimates based on the thresholds outlined in Table 6.53 in Section 6.3.6, and indicative (not exhaustive) references upon which the evidence in based.

''Integrated response options based on value chain management through supply management''

There are no global estimates of the impact on desertification of sustainable sourcing, management of supply chains, enhanced urban food systems, improved food processing, or improved energy use in agriculture.

Table 6.35 summarises the impacts on desertification of supply management options, with confidence estimates based on the thresholds outlined in Table 6.53 in Section 6.3.6, and indicative (not exhaustive) references upon which the evidence in based.
