Conservation of the wild Coffea arabica populations in situ6.3.3 Reserve suitability and zonesThe areas suitable for a reserve around Yayu and their degree of suitability are mapped(Figure 6.5). The summary of the results of zoning and reserve suitability classification arepresented in Tables 6.5 and 6.6. From all possible solutions of the order-weighted average(OWA), the result obtained by using order weights 0.6, 0.25, 0.15 was used for the finalzoning of the reserve, as the resulting suitability map included much of the undisturbed forestand was nearly a risk-averse solution with an ANDness of 0.725 (Figure 6.5; Table 6.4).The OWA2 (without constraint) option of reserve suitability (Figure 6.5a) showsthe potential forest areas that could fall within the three suitability classes. However, mostareas in the landscape are currently used by the local people for coffee production, farmingand settlement (Figure 6.4). Using such areas as constraint resulted in the suitability mapOWA1 in Figure 6.5b. Exclusion of such areas reduced the areas in different suitabilityclasses available for the reserve (Table 6.5).Table 6.5. Areas (in ha) in different reserve suitability classes.

The highly and moderately suitable areascover almost the entire undisturbed forest, which is about 28% of the total landscapeconsidered in this study (Table 6.5). The local people currently use about 72% of the area,either as managed forests for coffee production (26%) or as farmland and settlement areas(46%).117
