   The production of ${\Lambda }_c^{+}$ baryons produced directly at the interacting point is studied in proton-lead collisions collected with the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of $1.58{\mathrm{nb}}^{-1}$ recorded at a nucleon-nucleon centre-of-mass energy of $\sqrt{s_{NN}}=5.02$ TeV. Measurements of the differential cross-section and the forward-backward production ratio are reported for ${\Lambda }_c^{+}$ baryons with transverse momenta in the range $2<p_T<10$GeV/$c$ and rapidities in the ranges $1.5<y^{\ast }<4.0$ and $-4.5<y^{\ast }<-2.5$ in the nucleon-nucleon centre-of-mass system. The ratio of cross-sections of ${\Lambda }_c^{+}$ baryons and $D^0$ mesons is also reported. The results are compared with next-to-leading order calculations that use nuclear parton distribution functions.
