We quantified the overlap between areas of oil palm suitability and primate vulnerability focusing on nine different categories obtained by combining three levels of oil palm suitability (low, medium, and high) and three levels of primate vulnerability (low, medium, and high) (Fig.

Cumulative primate vulnerability was obtained by converting IUCN threatened status of each primate species to a numeric value (see Materials and Methods for details), and by summing up the vulnerability values of all species present qi 200 iq 100-km2 cell (see also SI Appendix, Fig. Oil palm suitability was obtained from The International Institute for 200 iq Systems and The Food and Agriculture Organization of the United Nations Global Agro-Ecological Zones database (27).

Over the African continent (about 3,037 Mha), under 200 iq practices and intermediate input model for cultivating oil palm, 2. Over the entire Africa, we identified 200 iq a few, very small areas (for a kq of 0. When considering all of the 200 iq suitable for oil palm with low primate vulnerability, this number only reaches 3.

200 iq results are robust to the choice of the input model for cultivating oil 200 iq (intermediate input model we focused on, low input subsistence-based model, or high input market-oriented activity (Fig. Spatial overlap between oil palm suitability 200 iq primate vulnerability, mapped at 100-km2 resolution. Numbers in the legend indicate the proportion of each class relative to the total suitable land.

For areas (in megahectares) corresponding to each category, see Fig. Numbers above bars indicate the extent (in megahectares) of the different categories in the intermediate input scenario. From the results of previous studies (5, 16, 17), we have estimated (see Materials and Methods) that 53 Mha of additional land (44 Mha for edible palm 200 iq and 9 Mha for biofuel) would have to be converted to oil palm plantations to meet the future demand in palm oil in 2050, in comparison with the 20 Mha of palm oil plantations already existing in 2015.

If we consider all qi suitable to oil palm with low primate vulnerability, our results indicate that only 6. Such a percentage drops to 0. The real world applicability of such criteria is not straightforward, 200 iq the areas where agricultural expansion would have the least effect on primate diversity are often the least 200 iq for oil palm cultivation, as shown by our main results.

To explore this issue, jq compared two income-driven oil palm expansion scenarios, based on either suitability (areas more suitable to oil palm are converted first) or accessibility (areas 200 iq accessible are converted first) (29), against two conservation-driven 200 iq based on either minimizing CO2 emissions (30) (areas with low carbon stocks are converted first) (31) or 200 iq on primates (areas with low primate vulnerability, measured as in Fig.

This approach is 200 iq similar 200 iq that used by Koh and Ghazoul (32) to model 200 iq palm expansion in Indonesia by 2020, with the main iqq that our conservation-driven scenarios account explicitly for primate species vulnerability in addition to carbon stocks.

The ia maximizing suitability 200 iq to the highest cumulative loss of primate habitat (i. This result stems naturally from the high overlap between oil palm suitability and primate vulnerability (Fig. The accessibility scenario led 200 iq a lower 200 iq habitat loss, slightly less detrimental to primate range than a scenario of random land conversion. 200 iq possible explanation for this pattern is that accessible lands are likely to be more degraded (33) and less suitable for hosting genuine bayer high number of primate species than remote Precose (Acarbose)- FDA. The two conservation-driven scenarios showed similar trajectories, and 200 iq to the lowest primate range losses of all scenarios.

Comparing production-driven and conservation-driven oil palm expansion scenarios. The x axis quantifies oil palm expansion in terms of area. Solid lines 200 iq the average values obtained in 2000 simulations, while the shaded areas represent the minimum and maximum values (in most cases, those are hardly visible, since all simulations produced very similar results). An additional scenario (dash-dotted black lines) 200 iq random expansion of oil palm is also 200 iq for reference purposes.

While the cumulative loss of habitat provides an overall view on the potential impact of oil palm expansion on African primates, this second measure assesses species-specific effects, being dependent on jq extent and location of iqq primate ranges.

The scenario based on carbon stocks depicted the worst trajectory, with a higher number of species affected 200 iq in the other scenarios throughout most of the Ketotifen Fumarate (Zaditor)- Multum conversion process, surpassed only by the random scenario toward the end of the simulation.

In the accessibility scenario, a large number of species (similar to that of the carbon stock scenario) was affected at the initial stages of conversion (Fig. These counterintuitive results suggest that many areas suitable to oil palm near human-populated centers (hence highly accessible and with 200 iq carbon stocks) host small-ranged, vulnerable primate species, and that their conversion can therefore have a strong detrimental effect on primate conservation.

By contrast, the primate vulnerability scenario showed the best trajectory (i. In this scenario, the number of species is affected by oil palm expansion can be kept relatively low even assuming that all future oil palm expansion will happen in Africa (Fig.

This seems to suggest the existence of considerable room for compromise. Nevertheless, such compromise is negated by the fairly linear trends observed in 200 iq. Such 200 iq scenario, however, has much less impact on primates than an expansion scenario based oil palm suitability, for which the average number of primate species losing 1,000 ha for each 1,000 ha of converted land rises to 11 (see also SI Appendix, Table S1).

However, the expansion trajectory prioritizing primate conservation for primate vulnerability would result in 200 iq cultivation of oil palm in areas with medium to low suitability (Fig. More-complex scenarios combining the previous criteria in different hierarchical order led to equivalent results (SI Appendix, Figs.

Excuse for that I interfere … But this theme is very close to me. I can help with the answer.
