Regardless of any error in the BIA's adverse rulings on credibility and corroborating evidence, the BIA — crediting Ndiaye and his evidence of past persecution — further denied him asylum because conditions in Mauritania have changed since his departure. See 8 C.F.R. § 208.13(b)(1)(i)(A); Ly v. Holder, 396 Fed.Appx. 304, 307-09 (6th Cir. 2010) (explaining that proof of past persecution raises a presumption of a well-founded fear of future persecution, a presumption the government may rebut with evidence of changed country conditions). Ndiaye does not contest this changed-country-conditions finding on appeal, and, as explained below, substantial evidence supports it.

The IJ's holding aligns with our decisions in several recent cases upholding "findings . . . that the changed country conditions in Mauritania reduce any objective fear of future persecution." Ly v. Holder, 396 Fed.Appx. 304, 310 (6th Cir. 2010) (collecting cases). Resisting this conclusion, Ly notes that the Country Reports also contain some evidence supporting his fear.
