Abstract


Increasing agriculture production and development demands agriculture innovations that enhance agriculture sustainability to reduce food insecurity. Agroecological cocoa agroforestry provide land sustainability benefits. Using cross sectional data from 400 cocoa farmers in Ashanti and Western regions of Southern Ghana, the present study analyses Agroecological impact of agroforestry technologies on cocoa farmers’ yield and household income in Ghana.
A propensity score matching model was employed to check unobservable factors for both adopting the technology and outcomes such as yield and household income. The results indicated that 37.0, 24.8 and 10.5 percent respectively adopted low, medium and heavy shade. The paper addresses heterogeneity by providing different computations for low shade adopters, medium shade adopters and heavy shade adopters respectively.
The results of the perception statements indicated that farmers have a positive perception on the agroecological cocoa farming which reflected in their mean perception index of 0.40 which indicates that in general farmers agree to various perception statements
The results of the Kendall’s coefficient of concordance test concluded that there is a reasonable degree of agreement among the respondents in the ranking of constraints to agroecological cocoa agroforestry at the three levels (low, medium and heavy).
Results of the propensity score matching indicated that the adoption of the agroecological cocoa agroforestry technology has positive and statistically significant impact on farmers’ cocoa yield and household income.
The study also revealed that gender, years of education, household head, farming experience, farmers based organisation and land tenure positively influence cocoa agroforestry technology. In addition sustainable yield, multiple revenue, fertility improvement, erosion control , weed control and biodiversity improvement positively influence cocoa agroforestry technologies.
The study recommends that shaded cocoa is the most sustainable form agroecological cocoa technology for a long term period hence Government should resource the extension agents to educate farmers on the proper management of agroecological cocoa agroforestry technology to increase yield since improper management of the shade levels can adversely affect yield.
