| Outline of Final Research Achievements |
Ambiguous and contested land rights in Africa is theoretically hypothesized to cause disincentive against potentially productive investment in agriculture but evidence varies across studies. We assess such disincentives across different land acquisition modes and find that it applies only to land with matrilineal origin but not to other acquisition modes. Variation in empirical studies is possibly explained by the difference in the share of lineage ownership across study areas.
Interventions in land tenure rearrangement and land registration are found to significantly enhance long-term investment and productivity after tree planting, while it is only tenure rearrangement that enhances the productivity. No gender bias is found for tree planting investment or productivity. However, the impact of land registration under female names is negative. Nominal use of female names in registration lead to lower productivity.
