Promoting local community participation in recognition of their indigenous knowledge is important for effective resource conservation. The aims of this study were to evaluate local community willingness and drivers of participation in mangrove conservation activities in the Rufiji Delta. Data were collected through focus group discussions, key informant interviews, semi-structured household interviews and participant and non-participant observations, across three designated management blocks - Northern delta (ND), Central delta (CD) and Southern delta (SD). Qualitative data were analysed using content analysis while quantitative data were analysed for descriptive and inferential statistics. Overall, the majority of respondents (88 %) agreed that it was important for the community to participate in mangrove conservation activities and 50 % of them expressed immediate readiness to participate if called upon. Zone wise, 50 % of respondents in ND and CD, and 42 % in SD indicated a moderate level of community willingness to participate in conservation. Age of household head, education level, source of income and awareness of mangrove governing laws were the most significant drivers positively associated with community willingness to participate in conservation activities. These findings suggest that for long-term management of mangroves, local communities should be adequately recognized as partners rather than as foes.
