Não há dúvida de que a água é um dos fatores de produção mais importantes na agricultura do Gana, a par da mão-de-obra. Mais importante ainda, quase toda a produção agrÃcola depende da precipitação natural. Por conseguinte, os rendimentos das culturas são invariavelmente baixos, uma vez que as chuvas são muito irregulares. O aproveitamento das águas subterrâneas para irrigação deve, portanto, ser seriamente considerado, uma vez que estas constituem cerca de 30,1% da água doce disponÃvel na Terra. A utilização potencial das águas subterrâneas de profundidade reduzida para a irrigação em pequena escala durante a estação seca é uma questão fundamental para o desenvolvimento da irrigação na zona árida do Gana. Os agricultores da sub-bacia de Atankwidi, na Bacia do Volta Branco, estão a recorrer cada vez mais à s águas subterrâneas como fonte de irrigação devido à indisponibilidade de águas superficiais na estação seca, daà a necessidade de investigar a sua disponibilidade e adequação, a fim de garantir a sustentabilidade da sua aplicação e uma possÃvel expansão na área. A geometria do aquÃfero na sub-bacia de Atankwidi foi, por conseguinte, delineada com sucesso utilizando técnicas geofÃsicas (VES e EM). A qualidade (adequação) das águas subterrâneas para irrigação também foi determinada com sucesso.
