Abstract
The primary objective is to determine whether strengthening a farmer's perceptions of the security of land tenure makes her more likely to make short-term and long-term investments in her land. The overarching policy question of interest is: “How do changes in property rights that strengthen a farmer’s perception of long term security over farmland affect a farmer’s decision to make investments---in particular, a long-term investment like agroforestry---on their own farms?” The evaluation breaks this into two key research questions for hypothesis testing. First, does the intervention strengthen farmer's perception of tenure security? And assuming it does, does it make the farmer more willing to make investments?

Interventions

Intervention(s)
Land Tenure Treatment: Activities under the land tenure intervention consisted of establishing Village Land Committees (VLCs), conducting participatory mapping, and facilitating the issuance of customary land certificates.

Agroforestry: Activities under the agroforestry intervention consisted of establishing Farmer Groups in treatment villages, establishing nurseries and distributing seedlings, and providing training and agricultural extension support services about agroforestry to farmer groups.

Experimental Design

Experimental Design
The study uses a four-arm village-level RCT. The groups are: control, agroforestry extension, tenure-security strengthening activities, both. Villages were randomized into these four treatments across four chiefdoms: Mnukwa, Mkanda, Mshawa, and Maguya. A comparison of findings in agroforestry villages versus control and land tenure versus control provides the average program impact on each of these components. The comparison of the average outcomes in the group receiving both program components provides evidence about synergy between agricultural extension and land tenure security.
