The Extent of Adoption of Agroforestry Systems and Practices and Conservation Implications in Kilombero District, Tanzania

Abstract

Agroforestry systems and practices are perceived to improve livelihood and sustainable management of natural resources. However, factors influencing their adoption in various regions require further investigation as they differ in biophysical conditions and societal characteristics.  This study was conducted in Kilombero district to investigate factors influencing the adoption of different agroforestry systems and practices in agro-ecosystems and farming systems. Household surveys, key informant interviews and focus group discussions were used in data collection. Descriptive statistics and Multinomial Regression Analysis in SPSS were used for data analysis. Results show that Agrosilvopasture and Agrosilviculture systems were the dominant agroforestry systems while the home garden and Mixed Intercropping were the dominant agroforestry practice. There is a potential in agroforestry systems and practices in terms of product diversification and biodiversity conservation though their adoption differed given the influence of different factors. Different factors were statistically significant as predictors of the adoption of agroforestry systems and practices. Residence period, availability of extension education/services, residence type and gender were the dominant factors influencing the adoption of agroforestry systems and practices. Farmers' oriented factors were critical in the adoption of agroforestry systems and practices. The study concludes that the practice of agroforestry will be more successful if the local priorities including socio-economic characteristics of the society are considered in designing systems and practices. Socio-economic characteristics of the communities that factor in conservation priorities should be addressed in the process of expanding the adoption of agroforestry systems and practices. Study recommends that productive systems and practices that contribute to household food and income are better adopted.
