农业在加纳具有重要的社会经济地位。这一部门约占劳动力的65%，约占国内生产总值的40%，约占通过出口获得的外汇的40%。虽然农业是该国经济的重要组成部分，但该部门的结构很脆弱，因为它在大约六个月的雨季中依赖农业。干旱和其他不合季节的天气给农民带来风险。在这些条件下，灌溉发展通过确保全年农业生产，为更大的粮食安全和农村地区发展提供了希望。
Agriculture has a central socioeconomic position in Ghana. This sector accounts for about 65 percent of the work force, about 40 percent of the gross domestic product, and about 40 percent of foreign currencies acquired through exports. Although agriculture is a key part of the country’s economy, the structure of the sector is vulnerable because it relies on rainfed agriculture during a roughly six-month rainy season. Droughts and other types of unseasonable weather pose risks for farmers. Under these conditions, irrigation development offers the promise of greater food security and the rural-area development by ensuring yearlong agricultural production.
