Primary Outcomes (End Points)
|
Before
(1) Number of forest trees and fruit trees planted in the game
(2) Number of forest trees signed up for in the Green Ghana Program 2023
(3) Perceived cocoa yield under different weather conditions in the game
(4) Beliefs about climate change risks, including the likelihood of abnormal weather, and the impact of abnormal weather on yield
(5) Beliefs about benefits of shade trees, measured by the marginal impact of shade trees on yield

Experimental Design (Public)
|
Before
Baseline surveys took place from February to March 2023 in Nkawkaw and from February to March 2024 for Sefwi Bekwai, right after the cocoa main harvest season. The interventions (described in the Intervention section) using a lab-in-the-field design were rolled out in March to May 2023 in Nkawkaw and will be rolled out in March - April 2024 in Sefwi Bekwai. Fewer days are scheduled for Sefwi Bekwai due to a smaller sample size compared to Nkawkaw.
Data collection on the GPS coordinates of shade trees on each farmer's plots will be conducted separately pending logistics details. A follow-up survey is planned. We will track attrition along the process and use Lee bounds if attrition is imbalanced across treatment groups.

To validate the key outcomes measured in the lab-in-the-field, we plan to distribute real tree seedlings to lab participants according to the amount they signed up for during the Green Ghana Day 2024 in Sefwi Bekwai from the end of May to early June 2024. The seedlings are free of cost and will be distributed to each community assembly place. All sign-ups are voluntary. The tree distribution is in collaboration with the Forestry Commission of Ghana, which has generously supported us with forest tree seedlings.
