The comparative performance of land sharing, land sparing type interventions on place‐based human well‐being

open access: yesPeople and Nature, Volume 5, Issue 6, Page 1804-1821, December 2023., 2023
Abstract Environment‐facing interventions impact the distribution, use of and access of natural resources and have important implications for all dimensions (material, relational, quality of life) of human well‐being (HWB). Yet conventional impact metrics routinely surpass the non‐material impacts which may be particularly salient in rural contexts ...
