The pion-nucleon sigma term ($\sigma_{\pi N}$) is an observable offundamental importance because embodies information about the internal scalarstructure of the nucleon. Nowadays this quantity has triggered renewed interestbecause it is a key input for a reliable estimation of the dark matter-nucleonspin independent elastic scattering cross section. In this proceeding wepresent how this quantity can be reliably extracted by employing onlyexperimental information with the use covariant baryon chiral perturbationtheory. We also contrast our extraction with updated phenomenology related to$\sigma_{\pi N}$ and show how this phenomenology favours a relatively largevalue of $\sigma_{\pi N}$. Finally, we extract a value of $\sigma_{\piN}=59(7)$ MeV from modern partial wave analyses data.
