Abstract In Ghana, the Pwalugu Dam in the Upper East is in the final planning stage. Whereas promoters of Ghana's first dams emphasized the need for generating electricity to modernize and industrialize the new nation, the planners of Pwalugu have focused on water issues. Due to climate change, droughts have had a devastating impact on local agriculture. The dam's primary purpose is an irrigation scheme and flood control. This essay historicizes these concerns by revisiting the Akosombo Dam, Ghana's largest hydroelectric dam, completed in 1965. The discussion juxtaposes personal recollections of dam-affected communities with reports by administrators, biologists, and social scientists. The essay draws on government records, scientific studies about Volta Lake, and oral histories. Ultimately, it argues, builders and administrators of the Akosombo Dam failed to address most water issues, despite ample knowledge about their existence. One hopes that these shortcomings will not be repeated in the Pwalugu project.

加纳的阿科松博大坝、沃尔特湖渔业和气候变化

摘要 在加纳，上东区的 Pwalugu 大坝正处于最后的规划阶段。加纳第一座大坝的发起人强调需要发电以实现新国家的现代化和工业化，而普瓦卢古的规划者则专注于水问题。由于气候变化，干旱对当地农业造成了毁灭性影响。大坝的主要目的是灌溉计划和防洪。本文通过重新审视 1965 年完工的加纳最大的水力发电大坝 Akosombo 大坝，将这些担忧历史化。讨论将受大坝影响社区的个人回忆与管理人员、生物学家和社会科学家的报告并列。这篇文章借鉴了政府记录、关于沃尔特湖的科学研究和口述历史。最终，它认为，阿科松博大坝的建造者和管理者未能解决大多数水问题，尽管他们对它们的存在有充分的了解。人们希望这些缺点不会在 Pwalugu 项目中重演。
