Abstract
The aim of this study was to examine the influence of Relative User Satisfaction (RUS) on the sustainability of Climate Change
Adaptation (CCA) practices in egro-ecological zones of Tanzania. Supported by the Technology Acceptance Model (TAM), this
study focus on determining the influence of self-efficacy, subjective norms, usage experience, perceived risks, output quality, results
demonstrability, perceived image, compatibility, usability and relevance, on sustainability of CCA practices. The study employed a
cross sectional research design , involving 295 respondents who are households heads adopted CCA practices in Chamwino and
Igunga districts, with data collected through household questionnaires, Focus group discussions (FGDs), and key informant
interviews (KIIs). Statistical analyses, including Descriptive statistics, Multiple Correspondence Analysis (MCA) and Multivariate
Ordered Probit model (MOVP) were performed. Results from the descriptive analysis indicated high preference of practices
including Trees Planting and use of Farmyard manure after funding, reasons being their simplicity, immediate benefits and
alignment with local knowledge. The findings from inferential analysis revealed that self-efficacy, perceived image, subjective
norms, usability and usage experience were positively and statistically influencing the sustainability of CCA practices after funding
period. Results from Multivariate Ordered Probit revealed Self-efficacy to have significant influence on soil water conservation
practices (β = 1.07, p < 0.001), Trees planting (β = 1.02, p < 0.001) and the use of farmyard manure (β = 0.99, p < 0.001). Perceived
image was also found statistical significant in influencing practices, with statistical significance p-value of 0.001. Subjective norms
was found crucial in influencing Ox-drain tillage practices (β = 0.99, p < 0.001), while usage experience and usability showed
moderate effects with statistical significance p-value of 0.01 and 0.05 respectively. The study finds that Self-efficacy, Perceived
image, Subjective norms and Usage experience serves as essential RUS factors in influencing the sustainability of CCA practices
after funding period. The study concludes that, ensuring sustainability of the practices require enhancing community participation,
simplicity of the practices and consideration of socio-economic factors. The study proposes establishment of targeted training, role
models system, incentive systems, monitoring frameworks and user-friendly guidelines to enhance self-efficacy, social influence,
and Usability for long-term implementation
