What problems might you infer or identify in using this type of photography?

Color would likely be problem for beginner's using CIR. While the contrast is certainly better than traditional color photographs, traditional color is also easier to understand for the layman. CIR, on the other hand, can aid it discerning vegetation growth and health, industry compared to agriculture, and land use, it does take some training to fully understand. When I first looked at the photos, I had no idea that red would mean vegetation.
