Abstract: The study investigated the Impact of Deforestation on the Achievement of Sustainable Development Goal-13 in selected local government areas of Rivers State. Two research questions guided the study. The study adopted a descriptive survey design. The population comprised 250 members of CBOs drawn from five local government areas- 50 from each LGA, namely: Etche, Ahoada West, Khana, Gokana and Opobo/Nkoro LGAs. The entire population was studied as sample due to its small and manageable size. A questionnaire titled “Deforestation on the Achievement of Sustainable Development Goal 13 Questionnaire” was used for data collection. Cronbach Alpha method was used to test the internal consistency of the instrument which yielded reliability indexes of 0.84 and 0.82. The research questions were answered using mean statistics. The study found out that respondents agreed that deforestation has serious environmental and socio-economic impacts on sustainable rural community development in Rivers State. The study also found out that community members have considerable level of awareness on the impact of deforestation. Based on the findings, it was recommended amongst others that government and its agencies as well as non-governmental organizations should collaborate with rural community leaders in organizing awareness campaigns on the importance of afforestation, reforestation and forest conservation as well the need to observe sustainable environmental practices in rural communities in Rivers State.
