Investigations of local representations about the environment allow for the elucidation of historical landscape transformation and the elaboration of strategies for environmental conservation. Thus, this study aimed to answer the following questions. How does the local population represent the possible changes in riparian vegetation over time? What historical events were responsible for these possible changes? How does the local population represent concerns related to the use andmaintenance of riparian vegetation? This study was carried out with 87 informants from three communities: two rural ex-settlement communities and one quilombo in Northeastern Brazil. According to the informants, therewere changes in the riparian vegetation. Themain causes of these changes include the type of agriculture practiced in the region and the building of a large dam to provide water to the city of Sobradinho in the state of Bahia. However, there was no significant difference between the number of informants who said that the changes were for the worse and those who said that they were for the better. In addition, the respondents reported an increase in the abundance of exotic species and a decrease in the abundance of native species. Thus, the importance of including this group of people in the process of the forest restoration that will occur in the region is emphasized because they possess information about the past vegetation changes and their causes. They can also indicatewhich species should be prioritized for replanting according to their usage needs and they understand the importance of conserving riparian vegetation.

0 consumo de água, assumido como sendo igual à Evapotranspiração Máxima (ETm) e o Coeficiente de Cultura (Kc) do sorgo sacarino foram estimados com base nas medidas de Etin realizadas em evapotranspirômetro de nível de água constante e da Evapotranspiraçáo de Referência (ETo) calculada pelos métodos de Penman, Classe A e Radiação. A ETm no cicio de 130 dias foi da ordem de 460 min. Os valores de Kc, correspondentes aos estágios iniciais do desenvolvimento da cultura e aos valores máximos, foram semelhantes aos recomendados pela FAO. No final do ciclo os valores estimados de Kc foram superiores aos da FAO em cerca de 30%. Foi observada estreita correlação entre a ETm (mm/dia) e o índice de Área Foliar (IAF) da cultura. A eficiência de uso de água foi da ordem de 56,7 Mg/ha/dia. |
