How do practitioners characterize land tenure security? por Masuda, Y.J., Kelly, A.C., Robinson, B.E., Holland, M.B., Bedford, C., Childress, M., Game, E.T., Ginsburg, C., Hilhorst, T., Lawry, S., Miteva, D.A., Musengezi, J., Naughton-Treves, L., Sunderlin, W.D., Velt, P.

“…Yet, incongruent characterizations of LTS (identifying the key components of LTS) by practitioners and researchers can limit collaboration and information flows necessary for research and effective policymaking. While there are systematic reviews of how LTS is characterized in the academic literature, no prior study has assessed how practitioners characterize LTS. …”
