Abstract Bengkulu is one of 10 provinces in Indonesia, which became a center of oil palm production. The aim of the study is to define how the determinant factors influence the oil palm smallholder farmer’s adaptation strategies on climate change in Bengkulu Province, Indonesia. Binary logistic regression method was employed to clarify the independent variables that influence farmers’ strategy adapted to climate change. Farmer experience and their household expenditure have the positive and significant effect on cropping diversification, while oil palm price has a positive influence in using land clearing without slash and burning. The factors that most influence the farmers' adaptation to climate change are farmer’s cooperation membership and membership of farmer group for agricultural extension. Because of their education and experience, they are not an important determinant on strategies adapted to climate change, but the farmer’s group for agricultural extension was very important in the adoption of comprehensive adaptation strategies to climate change, thus the understanding and skill of implementing strategies adapted to climate change among smallholder farmers needs improving by government extension agency. Therefore, ensuring access to information on climate change through extension agents is believed to create awareness and favorable conditions to adopt farming practices suited to climate change. It also means that improving the knowledge and skills of extension service personnel about climate change and adaptation strategies, and making the extension services more accessible to farmers is strongly recommended. For future work, new research involving more area with diversified ownership can be performed, not only smallholder farmer ownership but also private and state corporation ones. Moreover, the study about government action and policy for accelerating farmer's adaptation is important to be executed in the future.

As tecnologias de Agricultura de Precisão (AP) já são adotadas nas lavouras do Brasil, com técnicas cada vez mais produtivas, indispensáveis para garantir a liderança do País na produção agrícola. No entanto, ainda não existem estudos sobre a intensidade do uso das tecnologias de AP no País e dos condicionantes de sua adoção. O desafio central deste trabalho foi, então, investigar o processo de adoção e uso das tecnologias de AP alcançado pela indústria sucroalcooleira no estado de São Paulo. Para tanto, foram utilizados dados primários, a partir de encaminhamento de questionário a todas as empresas do setor sucroalcooleiro paulista, com o objetivo de conhecer não só o grau de adoção e uso das tecnologias de AP, mas também de verificar a influência das variáveis estudadas na probabilidade de adoção dessas tecnologias. As conclusões deste trabalho sugerem não apenas que o percentual de adoção das tecnologias de AP é elevado na indústria sucroalcooleira paulista, mas também que a probabilidade de adotar tais tecnologias é maior em ordem decrescente de importância, em usinas/destilarias de capital nacional, que fazem parte de um grupo empresarial, de orientação exportadora, de gestão profissional, e que utilizam maior percentual de recursos próprios para investimentos na empresa.<br>Technologies of Precision Agriculture (PA) are already a reality in crops throughout Brazil, using more and more productive techniques, crucial to ensure the country as the world leader in agriculture. However, studies on the intensity of the use of PA technologies in Brazil and the determiners of their adoption do not exist yet. The main focus of this study was, therefore, to investigate the adoption process and the use of PA technologies in the sugarcane industry in São Paulo state. For that purpose, it used primary data based upon a questionnaire submitted to all enterprises of the sugarcane sector in the state, aiming to figure out not only the adoption level and use of PA technologies in the sugarcane industry, but also to verify the influence of the variables studied on the probability for the adoption of the PA technologies. The conclusions of this study suggest that the percentage for the PA adoption is high in the sugarcane industry of São Paulo and also that the probability to adopt PA technologies is higher in decrescent order of importance in mills/distilleries of national capital, which are part of an export-driven group, of professional management and that use higher percentage of their own resources.
