A água e os alimentos são as duas substâncias mais essenciais para a sobrevivência da humanidade. No entanto, especialmente nas regiões áridas e semi-áridas, optou-se por importar os alimentos consumidos em vez de os produzir localmente, a fim de proteger os recursos hídricos disponíveis para outras utilizações domésticas, o que se designa por comércio virtual de água. Este estudo centrou-se nas regiões semi-áridas da Nigéria como um país de estudo de caso. A Nigéria é um dos principais países produtores de alimentos em África; no entanto, algumas regiões tendem a sofrer de escassez de água quando o clima é semi-árido. Neste contexto, o estudo considerou uma avaliação de (1) água virtual das culturas, que inclui as necessidades de água das culturas, produções, importações e exportações (2) pegada hídrica, que inclui as importações líquidas e a procura de água virtual. (3) Análise dos custos-benefícios, que inclui a avaliação do impacto do comércio de água virtual na economia das regiões através da análise dos custos-benefícios das importações-exportações. Todas as três secções deste livro são combinadas para fornecer uma compreensão abrangente da pegada hídrica e dos termos a ela associados, o que servirá como uma informação valiosa e significativa que poderá ser de grande importância para muitos cientistas.
