摘要:This Campbell systematic review examines the effect of interventions to strengthen land property rights on outcomes such as investment, agricultural productivity and farmer incomes in rural areas in low and middle‐income countries. The review summarises evidence from 20 quantitative studies (quasi‐experimental studies with statistical adjustment for bias) and nine qualitative studies. Land property rights improve productivity, consumption expenditure and income. However, caution is needed in interpreting this finding as there are few high‐quality studies available. The studies suggest that land property rights interventions contribute to welfare through improved perceived security and resulting long‐term investment. No studies showed that land property rights interventions improve access to credit.
