Impacts possible change may also negatively interfere productive processes, health conditions, quality life availability. this context, non-convention low cost technologies, with easy assimilation by communities, must be an approach deal problem supply diffused population. present paper, some these alternative importance for river basin integration transport across long distances are discussed, highlighting role management conservation sustainable use.
